FTMA Australia March 2013

In the last edition I touched on the benefits of being a member, however following the article we had a few enquiries for members who had forgotten their website access code and therefore we decided to send all members a new membership Folder for which we have received positive feedback.

The idea is to continue to build resources for members to add to their folders ensuring they have the information they need at their fingertips. This year we have already designed a new employment Contract for members to use as a template which recognises the Award requirements as well as a few policies which will be distributed to members shortly. Give us a call if you want access to these great resources.

National ConferenceRecently we completed a survey of fabricators in Australia to seek input in to what YOu want the 2103 FTmA Australia National Conference to focus on and we got great results.

Issues which will be on the program include; Housing Forecast by Harley Dale including a focus on the sustainability of the Australian Frame and Truss industry, Prefabricated Ground Floor systems, What’s new in the european market, Quality of information on plans, Delivery to top plate and issues focus on standards such as the new Timber Roof Truss Design standard and timber standards plus many other issues still being finalised.

The program is being locked in and will be distributed with the registration form shortly and if the survey is anything to

22nd July kindly sponsored by Hyne and Pryda. Delegates who choose to arrive early can spend the day networking over a game of golf or testing their skills in the Holden Racing Challenge before the official welcome at the Ice-Breaker BBQ. This event will be held at the Carlton united Brewery in Yatala in a relaxed atmosphere with beer tasting stations and matching finger foods as well as a state vs. state Beer Pulling Competition which will ensure plenty of laughs.

QT Gold Coast the outstanding venue for the conference is located at 7 staghorn Avenue, surfers Paradise, providing 5 star accommodation at affordable prices, and we guarantee all delegates will find the restaurants, bar and facilities unique and inviting.

The National Conference Dinner sponsored by multinail will be held in the exciting QT Gold Coasts Bazaar Restaurant where your plate is your passport and there are no rules on

I would like to begin this article by thanking the three new Multinail fabricators; Fortruss Frame and Truss (QLD), The Truss People (VIC) and Glencoe Group (VIC) for becoming members of FTMA Australia since the last edition of Multimail. These three members now have access to outstanding representation as well as access to the Members Only resources including the new Credit Application Form which saves their company over $3,000.

go by we are positive it will be a well attended event.

I am sure many of you have attended conferences before but there is one huge difference between other industry conferences and the FTmA Australia National Conference and that is ‘every topic and every presentation is to benefit the fabricator as the program is designed specifically for the frame and truss industry’. sure cross laminated timber and panelised houses are interesting but these issues do not affect a fabricators day to day business and therefore you won’t see it on our program. 100% of the conference will be of interest to fabricators and that is something FTmA Australia guarantees.

Another guarantee I am happy to make is the fact that unlike other events, the FTmA Australia Conference is organised to ensure delegate comfortability and plenty of time for networking. Conference sessions are short and quick allowing time for questions and discussions after each presentation and food breaks will be served amongst the static displays maximising delegates chance to view the displays and talk to sponsors.

All events are organised to maximise networking opportunities including the Red specials Activity Day on monday

which destinations to explore. up to seven chefs will prepare a mosaic of dishes to choose from providing a unique experience whilst allowing plenty of time to mingle.

Finally to finish off the conference, multinail will host a machinery expo at their stapylton Plant on Wednesday 24th July ensuring delegates make the most of their time away viewing the latest machinery on offer.

All in all this will be an event not to miss and we encourage you to book the 22nd – 24th July in your diaries now.

For companies wishing to be part of this exciting event we encourage you to contact FTmA Australia for the sponsorship packages which like the registration fee will be the most affordable going around whilst guaranteeing great exposure.

The User Defined Take-offThe user Defined Take Off (uDT) is a module in Multinail's current suite of software that enables the fabricator to automatically calculate dimensions, areas, intersections, bracketry, wall areas and more..

The user Defined Take-off (uDT) is a powerful, easy to use estimation tool that currently provides the user with the ability to;

1. Create any item for take-off, based on information in the stock file and the job, utilising existing database entries or you are able to request new ones to be added in order that you may create a formula to estimate quantities accurately and quickly.

2. use and edit pre-defined generic take-off lists provided in the software, The lists include trusses, battens, roof lining to name but a few.

3. Create and populate lists that contain individual items required for take-off, each Fabricator will have different, unique lists of ancillary and building items, that they use in order to estimate/supply trusses, wall frames, floor trusses, or general material to site.

4. Create and populate take-off groups that define a collection of items, The groups could be defined by item type, or taking it a step further by assembly components; making it easy to define and understand the take-off process.

5. Develop, define and edit your own equations to accurately calculate materials required for a job, Creating variables and constants as part of the equation building process, enables the user to quantify, and therefore estimate any item required for their kit assembly.

6. use pre-defined equations and variables for calculating values and items, existing system equations can be used as is or modified to suit the needs of the user.

7. save take-off lists and groups Create combined take-off lists that can be utilized to generate Bills of materials.


The Surveyor The surveyor will build on powerful capabilities within the user Defined Take Off, and using its link to the 3D model will in future provide the ability to;

1. Qualify materials nominated in the structural model,• Create libraries of materials to be estimated,• set default covering / cladding options for all surfaces,• specify all windows, doors, gutters and other components,• specify all structural components to be utilised within the model.

2. Quantify materials used in the structural model,• extract lengths, areas and volumes directly from the 3D model for entire levels,

specific rooms, or buildings;• measure all polygons (surfaces) off the 3D model,• measure all fixings, connections including tie-downs,• measure all bracing items / systems.

3. Cost materials used in the structural model,• Track costs to individual items, components or systems within the structural model,• Track costs of individual items, components or systems within jobs or projects,• Create new, or modify existing preferred default costing methods (margin, mark up).

4. Cost labour for all manufactured components in the structural model,

• Track labour costs of individual items, components or systems within jobs or projects ,• Track labour costs of individual items, components or systems within the structural model,• Create new, or modify existing preferred default labour costing methods for each

manufactured item (Roof truss, Wall frame, Floor joist).

5. Import or export surveyed data to 3rd party applications.• support 3rd party accounting packages,• support 3rd party point of sale systems.

6. Track Materials and Manufacturers,

• Track materials used to structural components,• Track manufacturers, suppliers, pricing and part numbers for detailed reporting.

The surveyor is a new module in The cornerstone suite of software that enables the fabricator to extract limitless information and quantities for the quoting of sundry materials such as plasterboard area, doors, windows, guttering, and more.

Background on production theory: efficient manufacture of Roof, frame and Floor trusses is only successfully achieved by utilising a smooth, continuously flowing production system. In simple terms a production system can be defined as having specific inputs supplied at the correct time, in the correct sequence and in the correct quantities in order to produce a tangible output. It doesn’t matter what the inputs are or how many processes are involved, the output is always composed of all the inputs less waste. The laws of physics stipulate that when matter is converted from one form to another there is no such thing as 100% efficiency and waste is always produced. As a result, waste within the Truss and Frame fabrication industry can be categorised into three specific areas:

• Material waste

• Process waste

• Labour waste

Once we recognise that waste is an inevitable bi-product of production and that 100% efficiency is physically unattainable, we can breathe a little easier and simply concentrate on minimising waste in all our production systems, or simply stated, “waste management directly effects output volume and efficiency.”

A production system within the truss and frame fabrication industry is composed of many seemingly unrelated processes, which interact together to produce the end product output. The more complicated and unrelated the processes are to each other, the less likely the output will be produced efficiently, accurately and cost effectively without extreme amounts of waste being created. However breaking complex processes down and grouping these smaller unrelated processes together in a logical sequence, helps in reducing waste and increases production efficiency.

It is important to remember that “Output Volume” and “Output Efficiency” do not mean the same thing. Output volume relates to the total quantity of output produced irrespective of how much labour and materials were used or how much waste was created. Output efficiency on the

Basics of

other hand relates to how much waste was reduced in order to process a finite amount of output.

An example comparing the differences between output volume and output efficiency is as follows:

1. Output volume is achieved by having each process completed as quickly as possible and is not reliant on the time taken for any other processes either up or down stream in the production system. This production methodology is also commonly called a “push system” of production.

2. Output efficiency on the other hand takes a holistic approach to the production system and groups like processes together in a pre-defined sequence where each process is directly reliant on the previous one. This production methodology is commonly called a “pull system” or “just in time” production.

Within the truss and frame fabrication industry, some fabricators only use the “push system” of manufacturing and believe that output volume more than makes up for increased wastage and other inefficiencies due to a rapid turnover of stock holdings and increased sales, but unfortunately this is not always the case. The primary downside of the “push system” production methodology is that if the business is setup to produce a fixed level of output, then this output quantity must be maintained irrespective of customer requirements and market conditions. An unintended negative consequence can occur if the customer wants to make product changes or puts back a delivery, then the end result can be additional waste generated in the form of wrongly made goods or an increase in product stock holding. This eventuality has now led to all three forms of waste being created. “Material waste” due to the customer changing the product specification, “Process waste” due to having to store the goods in-house for delivery at a later time and “Labour waste” due to making a product which is now not required to be delivered.

A “pull system” on the other hand will wait until the last minute or “just in time” to manufacture the product. This leaves the maximum amount of time between placement of order and manufacture for the customer to either change the product specifications or alter the required delivery date. unfortunately there is no such thing as a free lunch, so the major drawback of a “pull system” is the need to have additional resources up stream of each process in order to minimise labour and process waste due to product changes. However with a “pull system”, only 2 of the 3 waste areas are applicable, those being “Process waste” due to changing jobs around mid-flow and “Labour waste” due to waiting for the changed product to flow through the system. But in reality the labour wastage generated by product changes in the “pull system” can largely be mitigated by having a flexible, multi-skilled workforce that can be redirected up-stream in the production system so that the bottle neck is always the last process.

ProductionRoof, Frame, Floor Trusses In reality, most production processes utilise a “push-pull system” and it is only the degree of push or pull which changes the output quantity and efficiency levels. This is why simply increasing only one factor in the production process e.g. Labour, doesn’t give a true linear increase in output and eventually reaches a point of diminishing return. The theory of diminishing return states that each input added to the production system will result in an increase in output. However at some future point in time the continuous increase of single inputs will start to interfere with the production system. At this point, any

further inputs will actually reduce the volume and efficiency of output.


Consequently it is only when two or more factors in the production system are changed simultaneously that any increase can be mapped in a linear direction. For example:

Company A Company “A” manufactures timber boards with nails hammered in at regular spaces by workers with hand tools. The workers are required to pick up their own timber boards, nail and then stack them away when finished. The company wishes to increase production output so they hire an additional worker, but don’t buy him any tools. As a result, when he is placed into the production line, he has to wait until the worker beside him finishes using his hammer before he can borrow it. When he is finished nailing, he hands the hammer back and the cycle continues. As we can see, simply increasing the amount of available labour doesn’t guarantee an immediate or linear increase in production. In some cases output can actually decrease as the first worker has to wait for his hammer to be returned before he can commence nailing the next board.

Company B Company “B” manufactures the same nailed timber boards as company “A” and similarly the workers are required to pick up their own timber boards, nail and then stack them away when finished. The company wishes to increase production, so they hire a new worker AND buy him a new hammer. As a result, the new worker fits into the existing production line and this additional labour now provides a continuous and tangible output increase immediately. They may have increased their cost per board due to labour and tool purchases, but have offset that by the increase in their output volume. This result may not be entirely linear but is a dramatic improvement over Company “A”

Company CCompany “C” manufactures the same nailed timber boards as both companies “A” and “B”. However when they wish to increase production, they keep the same amount of workers but buy 2/3 of them nail guns. Due to the increased speed on the nailing operation, this company decides to take the last 1/3 of the workers off the nailing production line and devote them to handling material in-feed and material out-feed of the production stream. As a result the workers doing the nailing are no longer required to pick up and stack their own boards. By changing the in-feed and out-feed processes, moving the labour force around AND updating the tools used, the output of the company has increased dramatically and can be mapped in a linear or even exponential fashion. The added benefit now is that Company “C” has the flexibility of reducing labour if required, but can still maintain the same output levels they achieved before the upgrade. They now have increased efficiency and have dramatically reduced their costs per board produced.

Multinail Machinery’s annual catalogue publication is due to be mailed out in April. Packed with information on the latest timber truss machinery built locally for the Australian truss and frame industry. The standard range of equipment can be customised to meet your exact requirements and demands. For more information as it happens www.multinailmachinery.com


Also, the view that “it is not going to hurt” the house/trusses from a lot the house owners who have used the roof space as a storage area. But, is this true that “it is not going to hurt”? What is really considered to be “light weight”. Let’s see the design specs and the loadings of normal timber roof trusses and do an investigation.

some might argue that they don’t need to see designs as we all know that trusses have been built with safety factors. Also people could walk on the trusses without causing any damage. In fact, when you see the load impact on the trusses, this human load will be counted as a live load based on the Australian Timber Design standard. It should be emphasised that all items should be counted as a long-term live load in the roof in terms of the duration of stays.

Tech Torque By: Fox Huo · Design engineer

Many of us have seen people using roof spaces as storage. some people only put in THe empty boxes of home appliances, a few old books or other light weight items. However, some people install platforms on the truss bottom chords and throw tons of junk in the roof space, simply because it is a free extra space to the normal living area.

Let’s investigate with an example:

• An 8m span truss with a normal sheet roof in N2 wind area with 600mm spacing, 25 degree pitch, an A type webbing pattern and 90x35-mGP10 top and bottom chord. The load on the heaviest stressed members is less than 50% of its maximum capacities under dead load, dead load + live load and dead load + wind load.

In conclusion, roof trusses in a lot of cases are strong enough to carry extra weight. However, multinail does not recommend people to use the roof spaces as storage areas without pre-designing trusses for the storage area or having them checked by a multinail engineer.

Finally owners should plan the purpose of the trusses from the beginning instead of believing in what the other people say, for example:

“In my roof cavity I have comfortably stored boxes of books, memorabilia from my children, Christmas tree and decorations, boxes of clothes and odds and ends.” – From a representative of a roof ladder company. This is incorrect.

To interpret this, if additional loads were added to these trusses equal to the amount of weight difference between the sheet roof and the tile roof, the truss will function with extra deflections. But when the extra weight exceeds that, who knows?

The above is just an example as in reality the truss design results vary by many factors such as truss span, pitch, wind speed, webbing etc. No one could easily visibly judge how much extra weight could be applied to existing trusses. It will be good luck, if a truss designs within these capacities to handle extra deflections. It could be unsafe, if extra weight is occupying the inbuilt safety factors with extra deflections; or it could be dangerous, if the trusses are overloaded.

Furthermore, as seen in the highlighted words above, extra weight from roof space will lead to extra deflections of trusses which ends up cracking cornices or ceilings

• While the same truss, when it is loaded with a tile roof the members will nearly be up to 70% of their capacities.
