Executive summary
This report identifies the range of current methods and techniques of construction logistics being used, both
traditional and alternative, and the role they can play in reducing material waste. It shows what is driving their
use and what the barriers are to their increased uptake. The report will inform WRAP’s work in this sector to
ensure efforts are focused on the logistics methods where immediate and long-term gains can be made.
The context is WRAP’s 2006 – 2008 business plan, which is to:
� Divert 1.7m tonnes of construction waste from landfill or avoided primary extraction
� Influence the procurement of £10bn value of projects so that requirements are set for waste minimisation, recycling or recycled content
� Assist the construction sector to realise £50m savings by minimising site waste and recycling more.
The research included a desk study, logistics conference, interviews and workshops with logistics suppliers,
constructors and manufacturers, an online industry survey and a survey of CO2 generated by various logistics
methods.
Waste and logistics
There is compelling evidence that on a typical construction project about 15% of the material supplied to the site
(by value) is not incorporated in the construction and is therefore wasted. The interviews, workshops and online
survey show that there is wide agreement that better logistics would have a substantial effect on minimising
waste before it arises from the construction process.
The reasons found for waste arising in construction are:
Reasons Estimated impact by percentage of value of materials received
Over-ordering 5-10%
Damage 3-25%
Off-cuts 5-20%
Packaging (both
inappropriate and poor)
1-5%
Design Change 1-5%
Programming and Planning 1-10%
The drivers for improving construction logistics are the traditional drivers of time and cost, but a new driver has
emerged – the environment.
Methods and techniques of logistics
There are four basic methods of logistics used in the construction industry:
Method Which is Used by
Traditional
Method 1: The business goes to the supplier to pick up materials About 10% of the industry
Method 2: The business has materials delivered to site About 50% of the industry
Method 3: The business uses portfolio analysis to segment ordering
processes and call off arrangements
About 35% of the industry
Alternative
Method 4: The business co-ordinates a start-to-end process and tags
information, people and materials flows.
About 5% of the industry
An assessment of the potential impact on waste arisings and CO2 emissions shows that the greatest potential
benefits lie in moving the large constructors using method 3 to method 4.
Efficient Construction Logistics 2
In the alternative method there are seven main techniques:
Logistics planning across
full supply chain
Constructors have professionally trained logisticians who can plan across the
ranging, procurement, storage, distribution and back loading activities
Consolidation centre A distribution facility for materials that receives materials, equipment and plant
and delivers to the sites in consolidated loads
Just-in-time delivery to
work place
A service of frequent deliveries in work packs, 'pulled' just in time for the trade to
perform the next task
4th party logistics (4PL) A service to co-ordinate other logistics providers where there is more than one
supply chain
Logistics specialist on site A service to receive deliveries and distribute materials, equipment and plant - just
in time - so that operatives handle materials only when assembling or installing
Demand smoothing A service to enable the peaks and troughs in demand to be evened out over a
period of time
Integrated ICT system
across full supply chain
An interoperable information system that tags and tracks materials through take
off, manufacture, distribution, assembly and installation.
Conclusions and recommendations emerge from analysing the potential impact and timeframes of the techniques
and assessing the potential for change in various sectors and segments of the construction industry.
Recommendations The prime objective should be to influence procurement so that the tonnage diverted from landfill and money
savings can be achieved.
As a general rule, civil engineering is less wasteful than building because it already practices JIT (concrete,
aggregates, cabling, etc) and it has become adept at recycling waste either within the project or elsewhere.
Therefore the recommendations refer mainly to building.
The over-arching principles are:
� Make the business case for minimising waste
� Make logistics planning the norm
� Set up start-to-end information systems that include tag and track
� Understand the construction process and apply ‘lean’ principles.
Actions to see results within a year
The business case and logistics planning are the guiding principles for short-term gains.
In order to influence at least £10bn of procurement, WRAP should focus on new-build and refurbishment projects
in the following sectors and segments:
� Public – housing, schools, health, and central government and agencies including defence, prisons and police
� Private – housing and retail.
WRAP should focus on reducing the waste arising from over-ordering, damage, design change, and planning and
programming by encouraging take up of these alternative logistics techniques:
� Logistics planning across the full supply chain
� Consolidation centres
� Logistics specialist on site
� JIT delivery to the workplace.
Of these, logistics planning is the top priority because the need for consolidation and logistics specialist on site
will emerge from this action. JIT will follow as a consequence but this must be specified in the logistics plans.
Constructing Excellence is preparing a template for logistics planning and aims to have this ready for consultation
by the end of March 2007.
A two-pronged approach is needed to:
� Convince clients about the business case and to demand change from their main contractors
� Educate the main contractors (and their supply chain) about the business case and techniques that will deliver.
Efficient Construction Logistics 3
The risk of delay is a big driver to over-ordering. Therefore part of the solution is to ease penalties on trade
contractors (which some informed developers are already doing).
Unlike existing contracts with hauliers, contracts with logistics contractors need to reflect their involvement in the
risks of delivering the whole project.
Actions to see longer-term results
WRAP’s second strand of actions should focus on the long term. It should commence immediately and run
concurrently with the short term programme. Integrated ICT systems and lean processes are the guiding
principles for long-term gains. The work should also roll out gains pioneered in the short-term campaign.
The extra alternative techniques that should be encouraged in the medium/long term are:
� Integrated ICT.
� Demand smoothing
� 4th Party Logistics
� Off-site construction. Integrated ICT and off-site construction will alleviate the remaining reason for waste – off cuts – as well as over-
ordering, damage, design change, and planning and programming.
The recommended actions are all aimed at minimising waste. None of these actions (except perhaps
consolidation and onsite logistics team) will have any appreciable effect on the level of packaging. Evidence from
the workshops shows that the level of packaging is already finely balanced between the minimum needed to
ensure safe delivery and what is needed to survive the abuse suffered on site. Hence, although there have been
some advances in making packaging reusable (such as stillages for delivering windows), minimising packaging
waste will be difficult. Therefore WRAP needs to influence regulations and incentives that will encourage
suppliers to take responsibility for reusing and recycling packaging.

1.0 Introduction
1.1 Brief WRAP’s Tender Invitation dated July 2006 outlines the scope of work as follows:
The aim of this work is to identify the range of current methods of construction logistics being used, both
traditional and alternative, and the role they can play in reducing material wastage. The project should identify
what is driving their use and what the barriers are to their increased uptake. The project deliverable will be used
to inform WRAP’s work in this sector to ensure efforts are focused on the logistic methods where the largest
gains can be made.
The project will also be used to start building a sound evidence base, which can be used to advocate the use of
these techniques to reduce construction material wastage. The project will, as a minimum, provide the
information outlined below:
� Overview of the traditional and alternate methods of construction logistics market to include the level of usage, the situations when these services are most appropriate, who is providing the service, which
construction sectors are utilising these techniques, the benefits of and drivers for use and the barriers to greater uptake.
� Identify the key grouping of stakeholders in construction logistics, representing industry bodies, manufacturers, contractors, logistic providers and provide key contact details.
� Identify and categorise the various logistic options which are currently used in the UK construction industry and provide a description of each and examples from typical sectors.
� For each of the logistic categories identified above define:
• the current level of usage as a proportion of the overall market share
• the construction sectors they are used in (for example housing, leisure, retail, health etc.), with the
relevant market share of this sector
• the providers of these services including contact details
• the specific benefits of and drivers for their use
• the specific barriers to further uptake
• indicative effect on material wastage levels (for bench marking against traditional practices), and how
this varies from sector to sector
• the potential to apply to other construction sectors where not currently used
• whether it is likely to have an increased or reduced level of impact on CO2 impact due to transport
mileage.
� Identify logistics methods which could be used as exemplars of the benefits of their use in minimising material wastage.
� Analyses of the collated data and recommendations for the key areas where WRAP should target to deliver a decrease in material wastage in the construction sector through the use of alternate logistics methods.
WRAP’s business objectives
In its 2006 – 2008 business plan, WRAP intends to:
� Divert 1.7m tonnes of construction waste from landfill or avoided primary extraction
� Influence the procurement of £10bn value of projects so that requirements are set for waste minimisation, recycling or recycled content
� Assist the construction sector to realise £50m savings by minimising site waste and recycling more.

1.2 The project The following research activities and outcomes are summarised in Appendix 1:
� Desk study
� Logistics conference
� Workshops
� Industry survey
� CO2 survey.
Efficient Construction Logistics 7
2.0 Methods of logistics
Constructing Excellence established, through interviews and workshops, that constructors use four basic methods of logistics:
Table 1: Methods of logistics
Traditional
Method 1: The business goes to the supplier to pick up materials
Method 2: The business has materials delivered to site
Method 3: The business uses portfolio analysis to segment ordering processes and call off arrangements
Alternative
Method 4: The business co-ordinates a start-to-end process and tags information, people and materials
flows.
Method 1:
This is used by a business that takes orders on a jobbing basis and will then visits trade outlets to procure
materials piecemeal.
Method 2:
This is used by a business that has materials delivered to the site, typically larger projects with a bulk delivery
requirement supplied by trade outlets.
Method 3:
This is used by a larger business with a multi-project programme that can procure materials on a company basis.
Companies may have consolidated accounts or supply bases to improve/reduce administration costs and/or
materials costs through preferential volume discount. Materials will be delivered to site, however the
differentiator between methods 2 and 3 is that waste is reduced by improved processes.
Method 4:
This is used by a business that co-ordinates a start-to-end process and tags information, people and material
flows. Logistics for this type of organisation will include bills of materials produced by software linked to design
and they will most likely provide multiparty procurement deals for projects and apply volume discounts to total
project/programme turnover. Software is in place to share information and co-ordinate activities such as
ordering, warehousing, deliveries and invoicing.
Methods 1-3 are deemed traditional and method 4 is an alternative arrangement not commonly seen. Typically
methods 1-3 will use hauliers to provide transport between each step. Method four will use a logistics contractor
that will aid the application of timely resources.
Many companies, large and small, will use several of these methods on a project. From the main contractor’s
point of view, looking along the tiers in the supply chain the methods revert to lower order models. The caveat is
that the supply chain is a diamond and the levels of sophistication can rise again near the primary industry.
The drivers and barriers to a constructor adopting these methods are:
Table 2: Methods - drivers and barriers

No barriers – this is the entry level
Method 2: The business

segment ordering
processes and call off
arrangements
Potential to save money by strategic
buying and simplified administration
Inability or reluctance to plan ahead
Lack of critical mass

Method 4: The business
co-ordinates a start-to-end
process and tags
information, people and
materials flows.
Understand process and hidden costs in
traditional methods
Increasing environmental constraints
Clients’ expectations
Potential saving in materials (up to
15%)
Set-up costs
Unaware of business case
Relationships that do not encourage
shared risk, open book, etc.
Alternative techniques
Constructing Excellence established, through interviews and workshops, that there are seven techniques which
characterise the alternative method 4:
Table 3: Alternative logistics techniques
Logistics planning across
full supply chain
Constructors have professionally trained logisticians who can plan across the
ranging, procurement, storage, distribution and back loading activities
Consolidation centre A distribution facility for materials that receives materials, equipment and plant
and delivers to the sites in consolidated loads
Just-in-time delivery to

A service of frequent deliveries in work packs, 'pulled' just in time for the trade to
perform the next task
4th party logistics (4PL) A service to co-ordinate other logistics providers where there is more than one
supply chain
Logistics specialist on site A service to receive deliveries and distribute materials, equipment and plant - just
in time - so that operatives handle materials only when assembling or installing
Demand smoothing A service to enable the peaks and troughs in demand to be evened out over a
period of time
Integrated ICT system
across full supply chain
An interoperable1 information system that tags and tracks materials through take
off, manufacture, distribution, assembly and installation.
The logistics providers and manufacturers often used these terms but with significant differences and maturity
compared to the constructors:

3.0 Logistics providers Constructing Excellence identified 31 logistics providers with a declared interest in the construction industry. These are listed in Appendix 3. Having established the scope of alternative methods of logistics, Constructing Excellence surveyed those logistics
contractors with a declared interest in construction to see which companies offered these techniques. The results
are in Table 7. Gaps indicate no response. In this table,
Logistics means "we plan, co-ordinate and operate the complete logistics service"
Haulier means "we are mainly involved in moving goods. Others do the planning and co-ordination"
1 means “we do this in construction”
2 means “we do this in another industry but not yet in construction”
3 means “we do not offer this service”.
It is important to recognise that some of the companies claiming to offer certain alternative techniques may not
have grasped the full implications of this claim (for example, a small company that claims to offer an integrated
ICT system across the full supply chain). Also, large companies that claim to offer these services in other
industries may be a valuable resource for transferring tried and proven techniques to construction. However, the
learning curve for such transfers may be steep; what works in say retailing may not be readily transferable to
construction due to either different processes or ingrained resistance to change.

4.0 Analysis 4.1 Methods by sector and segment Constructing Excellence used the sector analysis from the desk study to create a matrix that shows the distribution of the four methods of logistics across the sectors and segments. The segments are sub-divided into new-build,
refurbishment, and repair and maintenance. The workshops considered initial estimates of the distribution of the methods shown in Table 8. Delegates
questioned and challenged the assumptions. Their most significant criticism was that the incidence of Method 1
was underestimated. This observation reveals that, in even the most sophisticated projects, there is a significant
proportion of small trade contractors still using this entry-level method of logistics when a higher level method is
not (or cannot be) imposed on them by the main contractor.
The estimated use of logistics methods is by proportion. For example the estimated use of method 1 in new-
build public housing is 25% (0.25). The values of construction in each segment are taken from Construction
Industry Segmentation and Analysis, AMA Research Ltd, 2006. The value of construction in each segment is the
product of the proportion by method and the value of the segment. For example the value of method 1 new-
build public housing is £2.6bn x 0.25 = £0.65bn. Constructing Excellence estimated the levels of waste shown
thus “x” and where the survey (Q16) suggested a different level this is shown thus “(x)”.

4.2 Potential to reduce waste and carbon dioxide emissions Constructing Excellence assessed the impact on CO2 and waste reduction to compare the potential gains from migrating to a higher method of logistics. Assumptions: CO2 level is derived from the CO2 survey, see Appendix 2. Waste indices are anecdotal as no
reliable measurements exist.

In terms of both CO2 reduction and waste reduction, moving from method 3 to 4 offers the best overall result.
In terms of CO2 reduction, there is no advantage in moving from method 2 to 3. And the potential to reduce
waste is small.
In terms of waste reduction, there is no advantage in moving from method 1 to 2. This therefore eliminates the
small contractors (a difficult group to influence) from the change focus.
In summary, this analysis indicates the focus should be on moving the major projects and contractors from
logistics method 3 to method 4. This is also the smallest and easiest group to influence.
Efficient Construction Logistics 16
4.3 Potential impacts of techniques and time frames Constructing Excellence assessed the potential impact of the various alternative techniques in method 4 and the timeframes needed to see results. By the third workshop, the list of alternatives was fixed and delegates were asked their views on the potential
impacts and timescales. There were no significant criticisms of the assessment offered by the researchers.
In this table, the potential impact on waste is assessed as high, medium or low. Timescales are assessed as
short (< 1 year), medium (< 3 years> and long (> 3 years).
Although not a logistics technique, off-site construction is included in this table because it was frequently
mentioned in the workshops and the survey, and because it would demand a change in logistics.
The techniques in this table are ranked starting with the greater potential impact and shorter timescales.

5.0 Conclusions
5.1 Focus on industry sectors and segments Applying selection criteria to the analysis of sectors and segments (see 4.1) indicates which industry sectors and segments offer the most potential for minimising construction waste.
The selection criteria used in this analysis are:
� Segments with a significant value of construction using method 3 logistics
� Segments that produce ~15% or more waste
� Segments where there is a relatively small number of major constructors that could (as a group) be more easily influenced than segments with a large number of smaller constructors (this will exclude repair and
maintenance work).
Table 11 shows the results. For example the potential value of procurement that could be influenced in public
housing is £0.65bn (new build) + £0.3bn (refurb) = £0.95bn annually.

5.2 Focus on logistics methods and alternative techniques Having concluded that moving from method 3 to method 4 offers the greatest impact on both waste arisings and CO2 emissions (see 4.2), the focus moves to deciding which alternative techniques offer the best potential gains, with particular emphasis on the short timescale.
Table 13 shows the six reasons why materials are wasted in construction, from Appendix 1.
Table 13: Reasons waste arises on construction
Reasons Estimated impact by percentage of value of materials received
Over-ordering 5-10%
Damage 3-25%
Off-cuts 5-20%
Packaging (both
inappropriate and poor)

Note that the impact of logistics methods to minimise waste from packaging is generally low because the balance
between the minimum needed for delivery and survival on site is already finely balanced. The manufacturers are
already subject to the Packaging and Waste Regulations. However, the ‘disconnection’ seems to be what
happens after delivery. It would therefore be better to focus on reuse and recycling of packaging.
Actions that should achieve results within a year
From table 10, consider:

It is universally accepted that the more effort put into planning, the better the outcomes. Logistics is based on
rigorous assessment of the need for materials, co-ordinating the manufacture and distribution. In essence,
logistics planning is the number one solution, as borne out in the workshops and industry survey. However, it is
not an easy discipline to impose in an industry that excels in fire fighting today’s problems.
When rigorously applied, JIT logistics is the most effective technique because, by definition, it permits delivery of
only those materials that are immediately required for construction. This simultaneously attacks four of the
Efficient Construction Logistics 21
reasons: over-ordering, damage, design change and programming and planning. But if considered in its own
right, there is a lack of tools and incentives to make it happen. That is why (on its own) it is assessed as a
medium timescale.
Case studies of Heathrow and Mid City Place show that the use of consolidation or logistics team on site has a
significant impact on JIT delivery. And when used together (such as at Stanhope’s central London sites that are
served by the London Construction Consolidation Centre (LCCC) they have a compounding effect on JIT and
therefore on waste. This is because consolidation and the onsite logistics team both employ Kanban systems to
‘pull’ materials when required and therefore enforce discipline and planning on a somewhat chaotic process.
The working exemplars that exist in the industry now offer springboards to implementing these techniques more
widely within a year.
Actions for longer term results
From table 10, consider:
Demand smoothing High impact Medium timeframe
4th party logistics Medium impact Medium timeframe
Off-site construction Medium impact Medium timeframe
Integrated ICT system across full
supply chain
High impact Long timeframe
These techniques all offer significant benefits and their practical implications will arise from a well executed
logistics plan. But none is likely to achieve results within a year.
Efficient Construction Logistics 22
5.3 Focus on stakeholders Following the conference, Constructing Excellence concluded that the main streams of activity needed to increase the impact of logistics on waste are:
� Making the business case for minimising waste
� Making logistics planning the norm
� Setting up start-to-end information systems that include tag and track
� Understanding the construction process and applying ‘lean’ principles.
Of these presenting the business case is essential to encourage greater take up of logistics planning. The
information and lean processes, although part of the business case and planning, will need a longer term to yield
results.
The construction industry is realising the benefits of integration because the change in thinking, as promoted in
the seminal reports Constructing the Team (Latham) and Rethinking Construction (Egan), have taken root. Many
key players have changed mindsets and are ready to ‘rethink’ logistics.
The business case is that up to 15% of the cost of materials could be saved if constructors could stop these
materials entering the value chain. The corollary is that of the 275 million tonnes of materials entering into built
environment per annum, the potentials saving in resources would be up to 40 million tonnes.
With better use of planning for logistics at the front end of the construction process and the associated
information flows and systems, waste could be minimised. This is because more accurate information regarding
quantities would indeed stop materials coming to site needlessly. To achieve this dividend the industry needs a
tipping point, led by the clients, to do the following:
� Produce a project logistics plan before any key appointment and ensure it reflects the client’s strategy and how information, materials and people will flow through processes. The plan will embrace alternative logistics
techniques that will respond to the client’s requirements and benefit the businesses in the supply chain and
the project.
� Move constructors from method 3 logistics (currently about 35% of industry) to method 4.
� Embrace the industry as an integrated supply chain.
� Measure the value in processes.
� Publicise and promote exemplars of alternative logistics.
� Use open book, target costs and risk and reward strategies in procurement. Extend to tier 1 and 2 suppliers and manufacturers to achieve the transparency needed to reward innovation and best practice.
The use of alternative logistics in the construction industry and its configuration will depend on client types and
project.
The unnecessary-cost drivers in the construction process could also be valued and reduce further the costs of
delivery. The unnecessary-cost drivers found in this research are the result of broken processes or lack of
evidenced-based management decisions. These are summarised below, together with the main causes of waste
and solutions discovered:

6.0 Recommendations
Given the short timescale of WRAP’s 2006-2008 business plan, Constructing Excellence recommends a clear focus on those actions that will achieve short-term results and those that will take longer to payback. The prime objective should be to influence procurement to reduce over-ordering so that the tonnage diverted from landfill and money savings can be achieved.
As a general rule, civil engineering is less wasteful than building because it already practices JIT (concrete,
aggregates, cabling, etc) and it has become adept at recycling waste either within the project or elsewhere.
Therefore the recommendations refer mainly to building.
The over-arching principles are:
� Make the business case for minimising waste
� Make logistics planning the norm
� Set up start-to-end information systems that include tag and track
� Understand the construction process and apply ‘lean’ principles.
Actions to see results within a year
The business case and logistics planning are the guiding principles for short-term gains.
In order to influence at least £10bn of procurement, WRAP should focus on new-build and refurbishment projects
in the following sectors and segments (see 5.1: Focus on industry sectors and segments):
� Public – housing, schools, health, and central government and agencies including defence, prisons and police
� Private – housing and retail.
WRAP should focus on reducing the waste arising from over-ordering, damage, design change, and planning and
programming by encouraging take up of these alternative logistics techniques (see 5.2: Focus on logistics
methods and alternative techniques):
� Logistics planning across the full supply chain
� Consolidation centres
� Logistics specialist on site
� JIT delivery to the workplace.
Of these, logistics planning is the top priority because the need for consolidation and logistics specialist on site
will emerge from this action. JIT will follow as a consequence but this must be specified in the logistics plans.
Constructing Excellence is preparing a template for logistics planning and aims to have this ready for consultation
by the end of March 2007.
Section 5.3: Focus on stakeholders shows who must be engaged in this process. A two-pronged approach is
needed to:
� Convince clients about the business case and to demand change from their main contractors
� Educate the main contractors (and their supply chain) about the business case and techniques that will deliver.
In most cases, the recommended entry channel is via the major main constructors who are working in the target
sectors and segments. This is because they are relatively few in number compared to the other stakeholder
groups and they lead established supply chains. The top players are listed in AMA’s report Construction Industry
Segmentation and Analysis. Once contact is made with these major players and they are convinced of the
business case, the next channel is via their clients.
Dialogue with clients and main contractors must include contractual terms offered to trade and logistics
contractors. The research revealed:
� Contracts that penalise trade contractors for delays are probably the biggest single cause of over-ordering because the risk of having insufficient materials weighs heavily on trade contractors who build it into tenders.
� Contracts with hauliers usually bear no relation to project risks. When stepping up from hauliers to logistics contractors, the terms of contract should reflect their vital role in delivering projects.
Efficient Construction Logistics 26
Housing
Entry to housing will be easier in the public sector than the private sector (which is three times as large) because
the public sector is already adopting change en masse via the Housing Corporation and the Housing Forum,
which is part of Constructing Excellence. Once a start is made in public housing, it will be a matter of transferring
the improvements to the private sector where there is a much larger potential gain.
Schools, health and central government
These segments are increasingly managed under framework agreements which have led to some consolidation
and integration of supply chains. These agreements are usually governed by key performance indicators that are
periodically changed to accommodate emerging business drivers (such as minimising waste).
Retail
This segment is dominated by a relatively small number of clients who have already caused big changes in their
supply chains, mainly driven by retail thinking. This is the only segment where the entry channel should be via
the clients. Again, the top players are listed in AMA’s report. But be aware that some of these commercial
relationships will make it difficult to realise the potential of waste minimisation, for example sharing the
dividends.
Logistics providers
There appears to be logistics providers ready to offer alternative logistics techniques (see 3.0: Logistics
providers). While the number with hands-on construction experience is limited there is an abundance of
expertise already providing similar services in other industries. These companies are well organised to manage
logistics planning, warehousing and distribution. But these cannot be relied upon in the short term because they
will have a learning curve to adapt to construction. So in the meantime it will be necessary to nurture the
emerging construction logistics specialists listed as ‘not ranked’ in the top 100 logistics companies.
Other agencies
The key agencies that WRAP should work with include:
� Transport for London (TfL)
� Greater London Authority (GLA)
� Chartered Institute of Logistics and Transport (CILT)
� Chartered Institute of Builders (CIOB)
� Construction Products Association
� Housing Corporation
� Constructing Excellence.
Actions to see longer-term results
WRAP’s second strand of actions should focus on the long term. It should commence immediately and run
concurrently with the short term programme. Integrated ICT systems and lean processes are the guiding
principles for long-term gains. The work should also roll out gains pioneered in the short-term campaign.
The extra alternative techniques that should be encouraged in the medium/long term (see 5.2: Focus on logistics
methods and alternative techniques) are:
� Integrated ICT.
� Demand smoothing
� 4th Party Logistics
� Off-site construction.
Integrated ICT and off-site construction will alleviate the remaining reason for waste – off cuts – as well as over-
ordering, damage, design change, and planning and programming.
Integrated ICT
Of these, the most important is Integrated ICT because it has the power to open communication along and
between supply chains. Experience in the retail and automotive industries show the importance of ICT in supply
chain integration, JIT delivery and traceability of components from design through manufacture, distribution,
assembly, installation, commissioning, operation, refurbishment and eventual demolition. This research has not
discovered any full systems in construction but there are partial systems operated by manufacturers and
constructors in isolation from each other. Therefore Constructing Excellence recommends that the entry channel
should be via those logistics suppliers who claim to offer such systems.
Efficient Construction Logistics 27
Demand smoothing
The construction industry is notorious for its irregular demand cycles. Demand smoothing (including forecasting)
is widely practised in the retail and automotive industries, but the patterns of demand are different. Hence,
Constructing Excellence recommends WRAP would derive the most benefit from demand smoothing via the
framework agreements that are consolidating demand in the public and private sectors. Funding cycles in public
sector procurement will also be important.
4th Party Logistics
4PL is a niche specialist logistics service that co-ordinates various supply chains for one customer (or main
contractor). In principle, it is transferable to any major construction project and the need should be apparent in
the logistic plan. WRAP should look to the logistics specialists with the know-how and technology needed to run
a 4PL service.
Off-site construction
Also known as pre-assembly and off-site assembly, this is not rated in the short-term actions because the
decision to construct offsite must start with outline planning and it takes some time to percolate down the supply
chain. Nevertheless, results should be expected in large procurements within a couple of years. This is a rapidly
emerging ‘sub’ industry and the recommended entry channel is via BuildOffSite, which is managed by CIRIA.
Packaging
None of the actions mentioned so far (except perhaps consolidation and onsite logistics team) will have any
appreciable effect on the level of packaging. Evidence from the workshops shows that the level of packaging is
already finely balanced between the minimum needed to ensure safe delivery and what is needed to survive the
abuse suffered on site. Hence, although there have been some advances in making packaging reusable (such as
stillages for delivering windows), minimising this waste will be difficult. Therefore WRAP needs to influence
regulations and incentives that will encourage suppliers to take responsibility for reusing and recycling packaging.

Appendix 1: Research activities and
outcomes
The research was done in five stages:
Desk study
Logistics conference Workshops Industry survey
CO2 survey
Desk study – Summary
This desk study is the first stage in the “Efficient Construction Logistics” study commissioned by WRAP.
Subsequent stages are Industry Survey (including CO2), Interviews and Workshops, Logistics Conference and
Technical Report.
The purpose of this report is to:
� assemble the knowledge that Constructing Excellence has obtained by desk study of the current state of
‘logistics’ and ‘waste minimisation’ in the construction industry
� suggest how better deployment of logistics could further reduce the amount of material waste in construction
and increase the proportion of residual waste that can be reused or recycled
� identify next steps in the study.
This report includes primary (factual) research as well as some secondary (interpretative) research based on
tangible and anecdotal evidence. Unless stated otherwise, statistics refer to the whole of the United Kingdom.
The waste investigated in this report is solid waste.
Scope and size of the construction industry
The annual value of the UK construction industry is about £107 million, which is about 9% of GDP.
There is a large proportion of small enterprises which increases the difficulty of implementing change.
The ‘Pearce’ report is the best available summary of how the industry behaves.
The ‘AMA’ report is probably the most up-to-date and extensive collection of industry statistics available.
Next steps:
� Use the extensive ranked lists in the ‘AMA’ report to identify organisations and then find key individuals (from the Constructing Excellence database) to include in surveys, interviews and workshops.
� Use this analysis of sectors and segments to select sites for visits to investigate the relationship between logistics and waste minimisation.
Scope and amount of waste produced in construction
It is apparent from a note provided by WRAP that there is conflicting data on the amounts of waste and the uses
to which it is put.
Although the amounts of waste quoted in the ‘Viridis’ report are probably low, it has been possible to extrapolate
equivalent data from the OPDM report. The conclusions in this section are the best guide available for the
amounts of waste created, recycled and ‘disposed of’.
The industry could work towards a two-stage objective to first eliminate waste sent to landfill then eliminate
waste sent to exempted sites.
Next steps:
� WRAP should review the analysis in this section for errors and omissions.
� Determine the scope of ‘exempted’ sites to see whether there is any valid use for this waste before using this figure in any waste elimination target.
Size and scope of the logistics sector serving construction
The value of distribution only is about £2bn in the construction industry. This does not include modern logistics
services that could reduce the amount of waste produced and increase recycling.
Efficient Construction Logistics 29
Compared with the retail and manufacturing industries (where logistics has already been fine-tuned), the
potential benefits of applying modern logistics in construction remain largely untapped. The biggest single barrier
to changing this is the inappropriate ownership of the logistics processes by the suppliers.
Next steps:
� Investigate the distribution of the four models of who ‘does logistics’.
� Investigate what main and trade contractors mean by logistics and how much they believe they are paying for that service.
Distribution channels
Distribution channels in construction are numerous.
The potential for both process and material waste is high.
Responsibility for logistics is fragmented.
Logistics methods used in construction
The methods of logistics vary according to the sophistication of the constructor and the technology used.
Eight principles of logistics, when applied to construction, show a large gap between best practice in construction
and manufacturing or retailing.
Consolidation is an ‘easy win’ which can impose logistical discipline on a chaotic industry.
Although this study focuses on material waste, the broader definition of waste includes energy as well as money
and human resources wasted through inefficient processes.
The Japanese automotive industry has led the way in defining waste (in terms of process and materials) and
designing production systems and managing the whole supply chain to achieve better results more efficiently.
These ideas are now widespread in the UK manufacturing industry. Through this rigorous management of the
supply chain, manufacturing has been transformed into an industry that is much less wasteful.
The construction industry needs to embrace these ideas in order to progress from dealing with the effects of
waste to eliminating the causes.
Next steps:
� Investigate the distribution of the four logistics methods and any other methods.
� Investigate how the methods of logistics vary according to sector and supply-tier arrangements.
� Investigate the take up of modern logistics methods using the eight principles of logistics as a guide.
� Investigate the existence and scope of reverse logistics processes in the construction industry.
Stakeholders in construction logistics
There is a wealth of data on trade associations and institutes with an interest in construction logistics. Following
the 80:20 rule, the approach will be to focus attention on those who are best placed to influence change and
those with the know-how (possibly gained in other industries) to make it happen.
Next steps:
� Obtain contacts from Construction Products Association for the directors responsible for packaging and waste minimisation (may be different people) in the top product manufacturers and distributors. Use this list to
investigate existing methods of logistics and potential to improve logistics processes and offer reverse
logistics.
� Involve members of CILT’s Construction Industry Supply Chain Forum in the surveys, interviews and workshops.
� Use the lists mentioned above to identify persons to represent clients, consultants and contractors in interviews and workshops. The agenda will be to investigate sector and supply tier arrangements, existing
methods of logistics, potential to improve logistics processes and offer reverse logistics.
Market share
The market share is unclear because the extent of logistics services supplied to the construction industry is
largely invisible in accounts and many companies have declined to give this information.
The UK’s top logistics contractors are already providing modern logistics services to the retail and manufacturing
industries. Hence they have much to offer in transferring these best practices to construction. But more work is
needed to establish contacts in the key logistics contractors who have so far “declined to comment”.
Next steps:
� Obtain introductions to those logistics contractors whose construction interests are listed as “unknown” or “declined to comment”. This might be best achieved via CILT.
� Interview the business development directors of logistics contractors mentioned above to determine what opportunities they see in construction and what value they can bring to improve logistics. Explore options to
offer and/or improve reverse logistics services.
Efficient Construction Logistics 30
Studies in logistics and waste minimisation
This work is incomplete.
Next steps:
� Obtain and draw conclusions from those selected references highlighted in Appendix 2 to inform the preparation of surveys, interviews and workshops. In particular, look examples of best practice in logistics
services provided for construction and other industries, and for evidence of successful logistics and reverse
logistics systems that may be transferable to construction.
Demonstration projects
This desk study reviews 25 demonstration projects with themes logistics and/or waste minimisation. This section
lists the benefits and lessons learned. The activities demonstrated were:
� using a specialist logistics contract on site
� using a Consolidation Centre for distribution
� dealing with contaminated soil
� using tag technologies
� logistics problems on congested sites
� recycling generally
� applying logistical solutions
� ideas from manufacturing
� demolition generally
� recycling plasterboard
� recycling aggregates
� analysing waste
� substituting materials
� co-ordinating projects.
Waste minimisation schemes
This desk study has identified potential actions to minimise waste and which stakeholder(s) is responsible. The
actions can be divided into three types:
� Reduce the amount of waste created in the chain of construction processes
� Increase the amount of waste that is recycled.
� Increase the amount of recycled materials and products that are used in new projects.
There is plenty of activity in various networks, approaches and schemes. What seems to be missing is a single
strategy for joining all these initiatives together.
WIN is a portal for accessing those decisionmakers dealing with waste in local authorities. An important caveat is
that most will be primarily involved in municipal waste.
Next steps:
In a survey of construction professionals, determine:
� the extent of use of these schemes and services
� other schemes and services being used to minimise waste.
With permission of WIN, include these decisionmakers in a survey to identify:
� those with an interest in construction waste
� local waste minimisation schemes that address or could be extended to address construction waste.
Impact of logistics on waste levels
Waste arises from five sources: over-ordering, packaging, damage, off cuts and demolition.
Modern logistics can be applied to every source to reduce its volume and/or increase recycling.
Current industry advice is mainly limited to dealing with waste (by recycling).
The industry has a chronic problem of over-ordering. Tackling this problem alone would reduce the volume of
waste enough to achieve the first objective of eliminating waste sent to landfill.
Tools exist (mainly in manufacturing and retailing) to make a radical impact on process and material waste.
Reducing process waste offers the best financial incentives to the stakeholders because it will have an immediate
impact on profits.
Once a culture is established to reduce process waste, the accompanying reduction in material waste will achieve
WRAP’s objectives.

Logistics conference
"The Art of Applying Timely Resources"
London, 21st November 2006
Constructing excellence arranged this conference to support three concurrent projects all with a logistics theme:
� London Construction Consolidation Centre - a two-year trial of Consolidation to serve sites in central London, sponsored by Transport for London
� Logistics plan for the construction industry, sponsored by the Department of Trade & Industry
� Efficient construction logistics, sponsored by WRAP.
There were some 50 delegates representing most of the stakeholders in construction logistics.
Welcome: Don Ward, Chief Operating Officer, Constructing Excellence
Chair: Steve Agg, Chief Executive, Chartered Institute of Logistics and Transport
Agg mentioned his background in retail logistics where cost and service have been the big issues. Now, a third
issue is challenging logistics - environment.
Presentation 1: New Drivers for Construction Logistics
Adrian Boughtflower, Freight Co-ordinator, Transport for London (TfL)
This presentation looks at the challenge of how to sustain the growth of London without clogging up the
transportation network. Boughtflower explains the success of the London Construction Consolidation Centre
which is consolidating deliveries to several inner-London sites at a warehouse outside the congestion zone. The
centre is showing substantial reductions in the environmental effects that road transport has on the capital.
Figure A1: London’s transport dilemma:
TfL’s key statistics for logisticians:
� By 2026 London’s population will grow by 1.2 million.
� By 2016 there will be 310,000 new homes and office space will increase by 7-9million m2.
� This work alone represents £10 billion of construction projects.
� TfL is planning for demand for goods and services to rise by 12% -15%, freight movements to increase by 15% as well as increased passenger movements.
� At the same time, road and rail capacity will fall by 10%.
Discussion 1: Drivers, barriers and stakeholders
Drivers: Cost, Quality, Environmental and Delivery for to utilise a holistic logistics approach or not. In other
words what will the drivers need to be to get you embrace logistics from your part of the industry?
Barriers; what is stopping people addressing logistics in their part of the supply chain, are they the relationships
in the in the industry, preventing you from embracing logistics, they have not thought about it, what knowledge
is required for you part of the industry to embrace logistics?
Who are the stakeholders and what do they need to do to drive logistics forward?
SUMMARY
Drivers (in no particular order):
2006 2016 2026 -15% 0 +15%
Rising demand
Falling capacity
Efficient Construction Logistics 32
• concern for the environment
• increased regulation
• how to make construction a sustainable industry
• concern about loss of materials
• concern about security
• logistics can improve KPIs: programme certainty, productivity, cost
• contractor demand for more efficient processes, for example JIT
• need to move deliveries away from peak times to avoid congestion
• potential to use existing fleets for 'reverse' logistics
• site constraints
• limited potential to recycle or reuse waste.
Barriers (in no particular order):
• invisible costs and no way to extract savings from improved methods
• lack of understanding of the problem
• fragmentation of the industry
• lack of leadership and champions
• business case not yet demonstrated
• disconnection between investment and benefit
• disconnection between designers and the supply chain
• ineffective ICT systems
• an immature collaborative culture.
Stakeholders:
• the community - understand the issues and demand change
• regulators - a joined-up regulatory framework that is enforced, monitored and reviewed
• project planners - more work on logistics plans and accounting for waste
• designers - understand the problem and facilitate change via the design and specification
• estimating and procurement - understand the waste component of cost
• manufacturing - innovation and collaboration
• delivery - adapt/adopt successful supply chain management systems from other industries
• installation - demand transparency of cost of supply and delivery
• disposal - maximise reuse and recycling and optimise use of vehicles
• specialists - educate the community and communicate to all stakeholders.
Presentation 2: Logistics centres and construction logistics in the urban environment
Gary Sullivan, Managing Director, and Ian Lister, General Manager, Wilson James
Following on Adrian Boughtflower's explanation of the benefits of consolidation, this impressive video
presentation shows how a consolidation centre works and the impact it has on both the environment and the
efficiency of construction. The video (192MB) can be obtained from Adrian Blumenthal.
Presentation 3: Logistics within BAA, from a tools and people point of view
Tim Brent, Integrated Logistics Leader, BAA
Brent shows how BAA's proposed redevelopment of Heathrow Airport will capture the many lessons learned in
the successful construction of Terminal 5. BAA is in no doubt that logistics has a key role to play and logistics
plans are already well advanced.
Presentation 4: Advanced supply chain optimisation
David Hills, UK Country Manager, Inform
Hills presents what was potentially a 'heavy' technical session in a lively and interesting manner. He
demonstrates how his company uses mathematical optimisation to set up the most effective delivery schedule,
using computer-aided scheduling. He gives examples of the hardware and tools needed and also how to strike
the right balance between customer service and cost efficiency.
Efficient Construction Logistics 33
Presentation 5: National distribution systems and how to save 18% of the cost of materials supply
using logistics
Matt Nicholls, Business Development Director, Wolseley
Nicholls explains how Wolseley embarked on a £100m investment programme three years ago to create a 'world-
class supply chain'. He describes their nationwide distribution system, together with a logistics flow chart along
the whole supply chain. The investment has yielded simultaneous service improvement AND cost reductions.
There is substantial use of consolidation in the supply process. He demonstrates environment benefits and
knock-on improvements in project efficiency.
Discussion 2
In the context of the stakeholders, what is important in relation to logistics?
What is the key Logistics input into the process steps that needs to be considered/developed for this stakeholder
group?
What is the key output into the next stage of the process?
What do you think the unnecessary-cost drivers are?
How can we improve flow between each step of the process?
SUMMARY
The groups, each representing a stakeholder, discussed what their inputs might be to a logistics plan and what
outputs they should expect from the plan.

Presentation 6: Uses of logistics in the UK construction industry and waste minimisation
Phil Wilson, Construction Project Manager, WRAP and Adrian Blumenthal, Special Projects Director, Constructing
Excellence
Wilson explains WRAP's remit in the construction industry and outlines their ambitions to reduce the waste arising
from construction as well as increased recycling. The current two-year business plan has specific measurable
objectives for its sustainability goals. The headline figures show that, on average, 15% of material supplied to
construction sites is wasted; up to 45% for some materials. Blumenthal outlines the results of a desk study
Constructing Excellence has done. He summarises the key reasons for waste arising: over-ordering, packaging,
damage, off cuts and demolition. This presentation sets the scene for the final discussion about how the industry
can prevent waste arising in the first place.
Discussion 3
How can waste can be minimised and prevented to coming onto site in the first place?
What are the broken processes that need to be fixed?
What does each stakeholder in the construction process need to address to fix the processes or stop waste
happening?
What are the key learning points from the day?
SUMMARY
Since this conference, Constructing Excellence has assessed the potential for each idea to minimise waste and the
time frame needed to implement the idea, shown in Table A2.
Short time frame means results within a year, medium time frame means results within three years and long time
frame means results will take more than three years.

The table on the next page summarises the ideas and suggests which stakeholders could act.
Notice how ICT systems will impact on nearly all stakeholders.
Following the conference, Constructing Excellence concluded that the main streams of activity needed to increase
the impact of logistics on waste are:
� Business case
� Planning
� Information (incl. tag and track)
� Process.
Key learning points (in no particular order):
• Industry needs to think through logistics from start-to-end of supply chains
• Industry needs a strong financial driver for change
• Rewards needed to encourage participation
• Regulation and cost (NOT collective ‘will’) will drive change will create the tipping point
• Need to develop and publicise new approach to logistics
• Need for robust ICT systems that enable communication along the supply chain
• Cost of disposal needs to rise further
• Need to invest in education in order to increase awareness of the problem in order to be able to
understand and improve
• Large number of small traders will be a particular issue in educating for change
• Many answers may already be 'out there', especially in best practice transferring from other
industries.

Workshops
Constructing Excellence held three workshops each attended by four to six members of these stakeholder groups:
� logistics contractors and consultants
� construction contractors
� construction product manufacturers.
Separate workshops we held for each stakeholder group in order to gain a clear stakeholder response by reduce
the potential for friction between stakeholders.

It was apparent from the workshops that, while communication was reasonably effective vertically, it was the
horizontal communication and alignment of the process that raised doubts.
Methods of logistics
Constructing Excellence proposed four basic methods of logistics. None of the delegates offered any significant
changes.
Traditional
Method 1 Business that goes to the supplier to pick up materials
Method 2 Business that has materials delivered to site
Method 3 Business that uses portfolio analysis to segment ordering processes and call off arrangements
Alternative
Method 4 Business that co-ordinates a start-to-end process and tags information, people and materials flows.
During the workshops the delegates described various techniques that they would expect in the alternative
method 4:
• Just-in-time delivery to workplace
• Logistics specialist on site
• Consolidation
• Integrated electronic information systems for take-off, manufacture, delivery, installation
• Off-site assembly (is this logistics?)
• Lean processes
• Inter-modal transport
• Synchronised supply chain
• Regional distribution centres
• Empowerment of logistics personnel to intervene in deliveries, common user plant, on-site storage,
wasteful activities
• Managing logistics agent to pull together all logistics operations (4th Party Logistics)
• Detailed logistics plan
• Demand smoothing
• Contracts that engage logistics supplier on project risks and rewards.
Constructing Excellence later divided these into cause and effects and concluded that the delegates had identified
seven alternative techniques:
� Logistics planning across full supply chain
� Consolidation centre
� Just-in-time delivery to work place
� 4th party logistics
� Logistics specialist on site
� Demand smoothing
� Integrated ICT system across full supply chain.
Reasons waste arises
Before the workshops, Constructing Excellence had identified four reasons. Delegates added two more, making
six main reasons why waste arises in construction. There was considerable debate about the percentage
contributions of all the reasons. Although some of the logistics specialists from other industries were quite
surprised by the average 15% waste figure offered by WRAP, none of the construction delegates disputed this
figure.
Over-ordering (5-10%)
Damage (3-25%)
Off-cuts (5-20%)
Packaging (both
inappropriate and poor)
(1-5%)
Design Change (1-5%)
Programming and Planning (1-10%)
Efficient Construction Logistics 39
Underlying causes
Although the delegates offered many causes for each of the reasons, common threads emerge in Table 6.

Barriers to change:

The percentage fee mentality is a disincentive
there is a reluctance to share knowledge
contracts for the inputs do not yet reflect the risk and rewards in construction.
Solutions:
There was general agreement among delegates that the by level methods of logistics were more likely to have
lower levels of waste. As the alternative techniques emerged there was general agreement that these would be
effective in minimising waste. In the last workshop (with the manufacturers) Constructing Excellence offered
Table 7 showing potential impact and timescales. There was no significant disagreement about this assessment.
Note that although off-site assembly is offered as a solution, it is not driven by logistics but would have a
significant knock-on affect on logistics.

The workshops also offered some specific solutions that may or may not have a logistics impact:
Table A8: Solutions
Over-ordering Education - the good news (opportunities) and bad news about waste
The level of waste is affected by decisions made in the early procurement
process
The solution will require more integrated-team thinking
There could be a milestone in the call-off process for the final order to
include in a carefully evaluation of remaining need.
Damage The key is better handling - who, equipment, how, training
Off cuts Design is a two-stage process. The principle of standardisation is
important that the concept stage and the minimisation and reuse of off
cuts is important that the detail stage.
Packaging The amount and method of packaging is already very finely balanced by
the manufacturers. The scope for a big impact here is low.
Other observations from the workshops:
The two logistics professionals who do not work in construction said they were shocked by the apparent degree
of inefficiency and level of waste.
The manufacturers noted unplanned orders typically 2-5% but they expected this to be much higher for
distributors.
There was frequent mention of the need for sites ‘pull’ only the materials needed, rather than permit the supply
chain to 'push' more materials are now needed.
There is a move towards buying clubs and fewer supply chains, which may have a beneficial effect on the level of
waste.
There is a need for logistics personnel on-site to be empowered to:
• control what comes to site
• co-ordinate on-site storage and common user plant
• intervene in wasteful activities.
Contracts need to be redrafted so that logistics suppliers engaged in project risks.
Logistics plan is needed very early in a project. This should become more detailed as it cascades down the
supply chain.
Manufacturers mentioned Materials Resources Planning (MRP) as a technique for forecasting and creating long-
term plans.
To manufacturers confirmed that they are now having conversations with customers about waste, and that this
had only started happening in the last 12 months. The driver for this is apparently the need to know how much
waste is likely to arise so that the trade contractor knows how much disposal will cost. This has led to some
manufacturers offering waste management service. This might be free (such as pallet removal and recycling) or
paid (such as recycling off cuts).
One manufacturer reported that they are investigating switching to plastic pallets with RFID tags to enable
tracking, recovery and reuse. It would require up to two years to get this going and a £1 million investment.
Half the manufacturers were involved in off-site assembly. Although this was a small sample, it was interesting
to note there level of waste was generally less than 5% and about 70% of that is recycled.
The manufacturers offered three issues for dialogue with the construction industry:
• Expose the cost of waste
Efficient Construction Logistics 41
• Those creating the waste must be responsible forgetting would have (although there is some
ambiguity about who is ‘creating’ it
• Designers must take more responsibility the minimising waste.
Consolidation centres could benefit manufacturers by:
• Quicker and easier deliveries
• The delivery time is no longer critical
• Handling after delivery is by ‘experts’, hence fewer disputes about damage
• The selection of vehicles for delivery is less critical.
Efficient Construction Logistics 42
Industry survey
The purpose of the survey was to test various ideas the project team had about waste and also to obtain ‘grass
roots’ opinions about the causes and solutions. The survey was conducted online by broadcasting an invitation to
the Constructing Excellence database of industry contacts. There were 190 valid responses.

Key messages from the responses:
� Delivery systems are cost driven, thus in bulk with full loads preferred, but don’t arrive when promised and are constrained by
vehicle use.
� Waste occurs because of lack of planning and co-ordination by all parties concerned.
� There is not enough use of JIT.
� Logistics services aren’t sufficiently geared to the variability of demand for materials (in terms of timing and quantity).
� A lot of construction processes are on a critical path and, if delays occur and co-ordination is lost, sub-contractors start missing their
window.
� There is little co-operation or culture of planning since suppliers just want to sell their goods and don’t have any incentive to programme
and plan for timely positioning of construction materials.
� Deliveries are outsourced to the cheapest man with a van or UPS or DHL who have no commitment to the project or the user.
� Many bread and butter materials are brought on site too early, laid down and have to be manually transferred, leading to damage, bad

The purpose was to see whether the
industry thinks the buyer or the seller
should be responsible for logistics.
Given the high proportion of lorries
either owned by manufacturers or
contracted to manufacturers, it is
surprising to see that respondents
claim about 60% of logistics is
managed by the buyers.
The same pattern exists for input and
output transactions.
Asked who should manage logistics,
the respondents would prefer to see
a move towards in-house
management. This probably reflects
a disenchantment with hauliers who
merely pick up and deliver.

15. On average, 15% of the materials supplied to construction
sites in the UK are not actually used in the project and becomes
waste. Why do you think this happens?
Key messages from the responses:
� Buyers over-order, rounding up ‘just in case’ and trying to avoid minimum delivery charges rather than avoiding waste.
� Damage occurs due to bad handling, poor site management, theft and the culture of people who are motivated only to get the job
done.
� The need for speed and the frequency of client changes make it cheaper to use new materials rather than take time to seek discarded
ones, especially since the 15% is covered in the costs at tender
stage.
� Design teams don’t work with architectural dimensions to reduce off cuts. Most waste is from floor, ceiling and wall finishes.
� The lack of proper communication in the supply chain means the construction process is fragmented and there is a history of
inaccurate estimating so sites become a mass of waste and surplus
material, supposed to be very ‘active’ but actually unsafe and messy.

18. For each of these reasons, what do you think is the root
cause and how can the logistics service reduce the amount of
waste due to this reason?
Over-ordering - root cause
Key messages from the responses:
� Estimators over-order to provide a safety net against damage/theft because they don’t want to pay for non productive labour waiting for
materials or to run short. The cost of delay is enormous compared to
the cost of over-ordering.
Key words and phrases:
Safety net
Enormous cost of delay if short of
materials
Inadequate information/co-ordination
Laziness
Efficient Construction Logistics 52
� Inadequate information or co-ordination, or just mere laziness at the planning stage makes for bad specifications.
� Tendering is a rushed process leading to inaccurate pricing and faulty figures which design teams rely on to their cost.
� Deliveries are not sufficiently well organised or reliable.
� More precision is needed in determining exact requirements of designer and client, plus material suitability – with more
understanding of the basics of lean, together with an assessment of
re-usability of materials.
Rushed, inaccurate tenders
Delivery perceived to be unreliable.
Over-ordering - logistics solution
Key messages from the responses:
� More training is needed at the planning and specification stage, using model-driven scheduling.
� The earlier involvement of the client, contractor and supplier and the sharing of more information are needed to ensure accurate
quantities.
� Planning teams should allow more time for the sub-contractors to have their input
� Call off contracts should be established through multi-project consolidation centres regionally sited and managed by logistic service
providers.
� The earlier logistics companies can be involved, the better, preferably at tender stage.
� There need to be more flexible stockholder and merchant systems allowing smaller quantities to be provided without cost penalty.
Key words and phrases:
Training
Sharing information
More time for trade contractors to
estimate
Call offs from consolidation centres
Logistics company included from
tender onwards
Supply system to be more flexible.
Inappropriate or excessive packaging - root cause
Key messages from the responses:
� Manufacturers and suppliers are the villains here, being highly conservative. They think more packaging is better packaging and
that packs look nice with the company logo. They seek to avoid all
risk.
� Despite their crocodile tears multi-nationals don’t give a damn about the environment.
� There is poor care of materials on site and poor skill levels too. But manufacturers have no incentive to collect piles of unwanted or
reusable packing.
� The practice of over batching on site (for example in bags of repair material) often ruins the planning of materials required.
� Contractors have smaller yards, rely on merchants to deliver and their small batching generates more packaging. Health and safety
requirements to reduce manual handling also lead to smaller
packages.
Key words and phrases
Suppliers avoiding risks
Big business doesn’t care
No incentive to reuse packaging
Small contractors tend to use small
batches, more packagaing
Inappropriate or excessive packaging - logistics solution
Key messages from the responses:
� Suppliers/manufacturers need to take ownership of packaging as well as product, building in principles or re-usability, making package part
of purchase agreements and running better take-back schemes
� Handling technology needs improvement and rationalisation – for
Key words and phrases
Suppliers need to take ownership of
packaging; take back schemes
Consolidation centres
Efficient Construction Logistics 53
example availability of half size pallets, having a system of rigid
cradle and returnable banding and wrapping, and paying more thought to lifting problems on site.
� Regional or central pick up points or consolidation centres could benefit contractors and logistic teams could specify to the supply
chain the requirements for products for particular sites.
� Supply chains need consolidating so products are pulled rather than pushed to the supplier
� Non reusable packing should be taxed.
Pull only products needed
Taxes
Damage - root cause
Key messages from the responses:
� Careless handling by drivers, operatives, site management and untrained workers. There is a lack of ownership of materials
between delivery to site and installation resulting in poor storage,
poor handling and thus more damage.
� Bad site management with a lack of training and supervision, storage being poorly thought out, and items often not dry and having to be moved several times.
� Inappropriate or incorrect use of tools and equipment, for example items are often delivered on large vehicles with appropriate lifting
equipment, but to sites which may be restricted in size, so the
equipment is useless and materials are pushed or dragged around
with what’s available.
� Items are often delivered too soon and/or insecurely on transport and people start opening packing to see what’s inside.
� Poor access to the site and poor skill levels all round.
Key words and phrases
Careless handling
Unsuitable site arrangements
Wrong vehicles and tools
Delivered too soon and then meddled
with.
Damage - logistics solution
Key messages from the responses:
� Sites need to be far better planned and managed, creating defined areas for materials storage for each contractor, protected from
weather and with a hard surface.
� Management on site should be by a logistics company or specially designated persons.
� Increase use of JIT practices and ensure logistic teams are flexible enough to respond.
� More training is needed for handling and the industry needs to develop a culture which values materials properly.
� Tie payments to the reduction of damage or provide some financial incentive to site operators.
Key words and phrases
Better site planning
Logistics specialist on site
JIT
Training in handling and value of
materials
Incentives ton reduce damage.
Unsuitable or faulty materials - root cause
Key messages from the responses:
� In joint top placed are inadequate quality control measures in production and poor specifications. Materials are often not tested for
the purpose intended and there is a lack of dialogue between buyer
and suppliers.
� Poor communication between the varies parties.
� Changes in specifications or design by the client at later stages.
� Whoever is procuring not procuring the right thing according to
Key words and phrases

Efficient Construction Logistics 54
specifications or drawings – sometimes they may be trying to
cheapen the job or designers may be specifying the wrong thing in the first place.
� The lowest price culture of clients.
Unsuitable or faulty materials - logistics solution
Key messages from the responses:
� Improve quality control systems at the manufacturer stage and install quality control checks at point of reception on site.
� Ensure specifications are carried out to better standards for purpose required with bench marks standard and inspection systems to avoid
materials needing to be rejected on site.
� Provide better training in design specification logistics and procurement with corrective action reporting systems.
� Have better communications in the supply chain and greater transparency of project requirements.
� Learn lessons from the automotive industry.
Key words and phrases
Quality control at site gate
Specify materials fit for purpose
Corrective reporting systems
Transparency
Automotive industry can do it!
Off cuts that cannot be used in the project - root cause
Key messages from the responses:
� Poor design planning and scheduling.
� Mass production systems, though having cost benefits, mean limited sizes and material loss or wastage. Standard lengths may be ordered
when non-standards would be better suited. Stock sizes will never
suit all industry requirements.
� Poor tradesmen/operative workmanship and perception that ordering more is cheaper.
� Poor design and scheduling, relying on operatives to ‘sort it out’ on site, even though their culture is to think of ease and time rather
than waste and cost.
� Designers may need to design sizes of rooms to reduce the need for cutting and to show awareness, for example of ceramic tile size.
Present dimensions can often be arbitrary.
Key words and phrases
Poor planning and design around
stock sizes
Reluctance to negotiate non-standard
sizes
Cheaper to use new than off cuts
Trades left to ‘sort it out’.
Off cuts that cannot be used in the project - logistics solutions
Key messages from the responses:
� Develop closer co-operation between contractors and sub-contractors and involve them in the design process. This would lead to greater
accuracy and understanding and, with education, to enable them to eliminate many cut-offs.
� Use off-site assembly as much as possible.
� Recognise the problem and form organisations that collect unwanted materials for free and match them to demand from other customers
or building sites.
� Train procurement staff about material sizes and link up with designers to make them aware of the implications of waste when
standard sizes aren’t used.
� Designers should talk to manufacturers to ensure new standards meet their requirements.
� Plan a cascade of recycling on site with high-value reuse systems and
Key words and phrases

19. Are there any reasons we've missed? What are the root
causes and can you suggest logistics solutions?
Key messages from the responses:
Causes Solutions
The negative culture that waste
doesn’t matter, and in any case is
paid for by contingency
Management should be made
properly accountable for waste
generated. Site agents need to
be fired up and given incentives
to reduce waste. Builders could
franchise out waste control to
sub contractors running waste
depots or contractors could
employ specialised individuals
charged with helping save waste.
Buildings are fundamentally over
complex and materials come in
too many finishes and
specifications, added to which ,
materials in mixed packages of
wood, metal, plastic and
cardboard, require a great
amount of time and effort to
separate.
Simplification and standardisation
Complacency and laziness of
many operatives
Education to waste not want not
approach, more sense of
ownership and awareness of
cash, then improvement of site
storage conditions to help them
adopt waste minimisation policies
Changes by client due to bad
briefing at design stage
Better communication and pre-
planning, ideally involving
suppliers, plus more quality
control at the pre-production
stage.
Collaboration and integration
between people and systems in
the building trade is poor with
little appreciation of each others’
roles
More understanding of each
others roles and the constraints
worked under is needed – for
example designers need more
practical knowledge of material
use. A little less haste and better
briefing sessions are needed.
Key words and phrases
Managers held accountable for waste
Standardisation
Education about value of waste

� Provide increased training and awareness of problems and potential solutions
� Standardise packages
� Shorten product ranges so that unused products from one project are suitable for use with the next
� Use more prefabricated products
� Make waste recycling containers mandatory on sites and use the law to change what is defined as waste so that it can be more easily
reused
� Remove VAT from materials made with more than 30% recycled material

22. What do you think would be the single most effective action
the construction industry could take to eliminate material waste
before it arises?
Key messages from the responses:
� Use more prefabricated products
� Disseminate good practice on waste management for small build projects as well as large schemes
� Get clients to understand the cost of going green so that short term thinking doesn’t prevent longer term involvement & get designers
and clients to agree fully on what are the goalposts at the outset
� Improve detail/precision of design so that waste is designed out and less has to be corrected on site
Key words and phrases
Off-site assembly
Publicise best practice
Expose cost of waste and benefits of
change
Design out waste
Managers made accountable
Taxes
Efficient Construction Logistics 58
� Make top level managers more accountable by publicising those who generate most waste
� Use taxes to penalise wasteful practice and/or make waste disposal statutory
� Give incentives to the work force, even have competitions to encourage them to suggest waste avoiding methods
� Ensure more time and commitment is afforded to tightening specifications and materials far ahead of starting on site
� Have localised storage sites to reduce transport costs and to allow trading of material between companies
� Have the building industry set up a waste recycling body
� Make less use of buying consortia that fragment effective long term supply chains and force them to use cheap low spec components.
Incentives
Allow time for planning
Localised distribution facipities.
23. Finally, thinking about your role that you told us in question
1, to what extent do you think you could influence waste
minimisation?

– Between November 2005 and July 2006
• Date. Supplier location, pallet equivalents, vehicle type
• 480 suppliers delivered in to Bermondsey CCC for Unilever, of which 341 had a recognisable address
• The 480 suppliers delivered 7673 pallets
• 341 suppliers used in model delivered 2928 pallets
• 97%delivery reliability
• 5-15% waste in centre at end of project.
• 79% reduction CO2 compared to type 2 and three

Method
� The C02 survey represented above seeks to look at logistics methods in the construction industry and the C02 implications for the various four types captured in our study. Based on the information gained at the LCCC the survey looks at the standard logistics network used in construction and has modelled each method based on loads. The results show that alternative logistics methods do not have a detrimental effect on C0s, as long as the utilisation of the vehicle is used and time delays are minimised. Typically placing a consolidation centre 4=8 miles from site will save 79% of the C02, based on the reduction of vehicles going to site and the reduction of Journey times.
� Method one comprises those contractors, typically jobbing or working in the RMI sectors, these contractors will journey to the local wholesaler using light van up to pick up materials for works lifting a maximum up to 1000KG, 1-3 pallets typically much less. The journey from the business to the wholesaler and site is 10-15 miles on average.
� Method two comprises the wholesaler delivering to a site using LGV vehicles up to 26 tonnes in weight, (average delivering in a multi drop process, this utilisation of trucks and loads is 34% better than method one. Typically 7-9 pallets min.
� Method three as above however 60% or materials delivered to centre direct from wholesaler and 40% from manufacturer, these vehicles travel to site and will spend approximately 1.5 hours weighting and unloading at the site entrance, Again load is 7-9 pallets. C02 as method two.
� Method four comprises tagged information and materials flows using just in time methods, from order, to delivery to centre and delivery to site using consolidated loads, Vehicles into to centre\(as would be delivered to method 2 and three) is 2500 vehicles compared to 730 vehicles out consolidated load, this model saved 79% of the C02 on Final 8 miles., hence .33 factor.
� Information on Inter modal shifts for the delivery of construction materials and its impacts on C02 are negligible and suited to major projects, where materials such as aggregated and steel are consumed at 1300 tones/ 600 tonnes respectively per week and that there is an adjacent rail head., the uses of inland waterway could be used, the loads to be carried on narrow boat is up to 150 tonnes and 350 tonnes.
