WAIKANAE DUPLICATE RISING MAIN CONSTRUCTION ADVANCEMENT

PURPOSE OF REPORT

1 This report seeks approval to sign the Memorandum of Understanding with the NZ Transport Agency (NZTA) to accelerate the construction of Waikanae Duplicate Rising Main (WDRM).

DELEGATION

2 Council has the authority to consider this matter.

BACKGROUND

3 The Waikanae terminal wastewater pumping station 009 transfers all wastewater effluent generated by Waikanae to the Paraparaumu Wastewater treatment plant (WWTP) for treatment.

4 The wastewater is pumped along a single 5km long “rising main” pipe to the treatment plant and there is no redundancy for the pipe.

5 The capacity of the existing pumping station is limited by firstly the power supply to the station and the pressure rating and size of the existing rising main. The existing pumping station has a pumping capacity of 137 litres per second (‘l/s’).

6 A three stage approach to upgrading the pumping station was developed with the first two stages now completed.

7 Stage one included the construction of 200m3 of emergency storage at the pumping station to provide buffering of flows during wet weather or pump station outage.

8 Stage two included the construction of a second wet well with new pumps, refurbishment of the existing wet well and associated pipework and odour control for the station. The redundancy and additional capacity provide by the second stage can’t be fully utilised until all upgrades are complete.

9 Stage three includes the installation of a duplicate rising main along the MacKays to Peka Peka (M2PP) Expressway designation, connection to the pumping station along Te Moana Road, connection to the Wastewater treatment Plant at Paraparaumu and upgrading of the power supply at the station. These complete the proposed upgrades to the pumping station providing additional capacity for future growth in Waikanae to 2061. In the 2012 Long Term Plan (LTP) this work was originally proposed to commence in 2016/2017.

10 With the development of the M2PP Alliance (a formed entity between NZTA, The Fletcher Construction Company Limited, Higgins Contractors Limited and Beca Limited) Council identified potential construction synergies/savings and advanced early stages of the rising main construction in the 2015 LTP with the programme information available at the time.

11 Working closely with the M2PP Alliance significant benefits were identified in advancing further sections of the duplicate rising main while the Expressway is under construction before the road is open to traffic. These include crossing the Waikanae Bridge and the section along the Cycleway Walkway and Bridleway (CWB) north of the Waikanae Bridge adjacent to the 510 Retaining Wall.

12 In November 2015 the Corporate Business Committee considered report IS-15-1748 (copy in appendix 1) and resolved to advance construction of these sections of the WDRM in 2015/2016 in conjunction with the construction of the M2PP Expressway. Funding was achieved within the existing annual 2015 Long Term Plan (LTP) Wastewater capital budgets through reprioritisation of three existing wastewater capital projects. The existing $4.05m was redistributed across years 2015-19 as follows: $1.75m, $200k, $100k, $2.0m.

13 Any further advancement of stage three upgrades would require increases in funding in early years in excess of that provided in the 2015 LTP. Discussions with the M2PP Alliance and NZTA have identified a mechanism to provide the required funding to complete the balance of the duplicate rising main in the expressway designation by the end of 2016/17 rather than returning at a later date to complete the sections along the CWB and local roads.

14 The DRAFT Memorandum of Understanding – Wastewater Pump Station WSP009 Rising Main (MoU) attached in appendix 2 has been prepared and allows the M2PP alliance to deliver the rising main installation and provides a funding mechanism to complete the rising main within the expressway designation without further movement of the 2015 LTP budget timings. Final legal reviews are required before it is signed.

15 The sections of rising main outside of the designation, along Te Moana Road to the pumping station and to the WWTP at Paraparaumu and the power supply upgrade are not covered under the MoU and can be delivered within the current four year LTP programme in 2017-19 to complete stage three of the upgrade. Construction of the WDRM along Te Moana Road would occur after the completion of the interchange reducing total disruption in this area and the connection to the WWTP can be made from the duct already in the expressway without impacting CWB users.

ISSUES AND OPTIONS

Issues

Project Funding and Scheduling

16 The re-prioritisation of wastewater budgets in November last year has allowed the Waikanae Bridge crossing and the section along the CWB north of the Waikanae Bridge adjacent to the 510 Retaining Wall to be included in the 2015/16 capital works with significant benefits.

17 The Council has continued to work with M2PP to refine the design, construction budgets and timing to identify further synergies and savings in the construction

of the WDRM. To improve the accuracy of costings and work estimates the M2PP Alliance recently tendered all the remaining WDRM sections needed to be completed along the expressway designation. This has resulted in a revised project cost estimate of $4.0 million if undertaken in conjunction with the construction of the expressway.

18 NZTA and M2PP Alliance have prepared a MoU that allows the construction of works within the expressway designation to be undertaken by the M2PP Alliance. Funding would be provided in the short term by NZTA, through an increase of $2.1m to the forecast NZTA subsidy. This funding would be recovered by NZTA in 2018/19 through reduced NZTA roading subsidies.

Procurement and resourcing

19 The construction of the rising main is a substantial project requiring contract management and administrative support processes and resources. The original staging of the construction also allowed the commitment required from the Council to be managed within the existing contract delivery processes and resources related to the M2PP project.

20 Advancing the works increases the resource commitment required by Council in the short term. This can be mitigated by working with the M2PP design and procurement teams to take advantage of the Alliances resourcing, while maintaining value for money by procurement through competitive tendering. This also brings the benefit of improved coordination of individual works areas with the M2PP programme and mitigates contractual claims from delays or coordination costs.

21 This model where Alliance teams manage the procurement and construction of Council infrastructure, under Council guidance, has worked successfully on other works. The Council then reimburse the Alliance for the costs to complete the works.

Memorandum of Understanding – Wastewater Pump Station WSP009 Rising Main (MoU)

22 The DRAFT MoU between NZTA and Council and provides for the M2PP alliance to deliver the construction of the WDRM along the expressway designation in conjunction with the current construction programme and eliminate future disruption for CWB users and road users at Te Moana interchange.

23 The MoU works have been separated into two parts separable portion A and B. These portions reflect the works that have already been agreed for advancing in portion A and the balance of works to complete the WDRM along the expressway designation in portion B. The scope of the WDRM M2PP advanced works is shown in the plans in appendix 3.

24 The MoU sets out the desired outcome to accelerate the design and installation of the WDRM within the expressway designation to avoid unnecessary costs or disruption to both parties. It sets out the respective responsibilities, risks, joint control group governance model and commercial approach and funding to meeting the outcome.

Options

Option one – Continue with current scope of advanced works

25 This option maintains the existing advanced works programme and project re-prioritisation approval by the CBC in November last year. This takes advantage of the construction efficiencies at the Waikanae Bridge and 510 Retaining Wall sections where retrospective installation would attract additional costs to manage traffic and alternative construction techniques.

26 It also eliminates the need to excavate the local road surfaces at Otaihanga and completes the crossing of the Te Moana Interchange.

27 The completion of the rising main along the balance of the cycle, walk and bridle pathway adjacent to the Expressway and along Te Moana Road to the pumping station would still need to be completed at a later date. This would require the disruption of the use of these locations.

28 The current budget schedule is set out below:

Year 2015/16 2016/17 2017/18 2018/19 Total

Budget (,000)

1,750 200 100 2,000 4,050

Option two – Accelerate the completion of the WDRM

29 This option accelerates the completion of the WDRM along the expressway designation and eliminates the need to disturb these sections again to complete the stage three upgrades.

30 It provides a funding option through utilising increased subsidy funding from NZTA for roading in 2016/17 to offset the increased costs of the WDRM installation with no impact to the LTP budgets.

31 Competitive pricing is achieved through the use of tendering through the M2PP Alliance procurement model.

32 This leaves the rising main sections outside of the designation, along Te Moana Road to the pumping station and to the (WWTP) at Paraparaumu and the power supply upgrade remaining to complete stage three in 2017-19. These could be completed within the current four year LTP programme

Preferred Option

34 Option two is the preferred option where the WDRM completion is accelerated along the expressway designation through the signing of the MoU.

CONSIDERATIONS

Policy considerations

SIGNIFICANCE & ENGAGEMENT POLICY

35 The signing of the MoU on behalf of Council was reviewed against the significance policy and considered to have a low level of significance.

Legal considerations

36 There are no statutory requirements related to this proposal.

Financial considerations

37 The preferred option is considered to be prudent management of capital investment funding that:

Minimises the cost of the project by coordinating works with the construction of the M2PP Expressway at critical sections along the alignment and staging completion of the balance of the rising main over four years;

Manages the advancement within the 2015 Long Term Plan wastewater capital budgets by using advanced funding through the NZTA roading subsidy to fund advance works;

Delivers the required upgrade to meet the projected growth.

Tāngata whenua considerations

38 There are no known issues for consideration relating to Iwi with the signing of the MoU to accelerate the construction of the project.

Consultation already undertaken

39 No formal consultation has been undertaken to date.

Engagement planning

40 The staging of the construction of the WDRM was set out in the 2015 LTP and was consulted on prior to adoption.

41 The acceleration of the WDRM through the MoU does not impact on the level of service to the community and it is considered an engagement plan is not needed to implement this decision. A media release to advise the community of the results achieved by working with the Alliance to deliver this project may assist in “informing the community” about progress on the long term plan.

Publicity

42 The approach to managing the staging of the construction of the WDRM was publicised in the 2015 LTP.

Purpose of Report: For Decision

WAIKANAE DUPLICATE RISING MAIN CONSTRUCTION ADVANCEMENT

PURPOSE OF REPORT

1 To seek approval for the reprioritisation of the 2015-2018 wastewater capital budgets to advance the construction of Waikanae Duplicate Rising Main (‘WDRM’).

DELEGATION

2 The Corporate Business Committee has delegated authority to consider this report under the following delegation in the Governance Structure:

Section B.3.7 Annual Planning

7.2 Authority to re-allocate funding already approved by the Council as part of the Annual Budget process provided that the re-allocation of funds does not increase the overall monies committed in the budget and is consistent with the existing LTP strategic and policy framework.

BACKGROUND

3 The Rauparaha wastewater pumping station transfers all wastewater effluent generated by Waikanae to the Paraparaumu Wastewater treatment plant for treatment.

4 The wastewater is pumped along a single 5km long “rising main” pipe to the

treatment plant and there is no redundancy for the pipe. 5 The capacity of the existing pumping station is limited by firstly the power supply

to the station and the pressure rating and size of the existing rising main. The existing pumping station has a pumping capacity of 137 litres per second (‘l/s’).

6 A three stage approach to upgrading the pumping station was developed with

the first two stages now completed. 7 Stage one included the construction of 200m3 of emergency storage at the

pumping station to provide buffering of flows during wet weather or pump station outage.

8 Stage two included the construction of a second wet well with new pumps,

refurbishment of the existing wet well and associated pipework and odour control for the station. This upgrade provides redundancy for the existing pumps and additional pumping capacity in preparation for the installation of the duplicate rising main in stage three. The additional capacity provide by the second stage

of the Rauparaha pumping station upgrades can not be fully utilised until the duplicate rising main is constructed.

9 Stage three includes the installation of a duplicate rising main and upgrading of

the power supply to the station that allows the additional capacity in stage 2 to be fully utilised. Stage three was designed to provide additional capacity for future growth in Waikanae to 2061 and was originally planned for commencing in 2016/2017 in the 2012 Long Term Plan.

10 With the development of the Mackays to Peka Peka (‘M2PP’) Expressway

programme, the opportunity to coordinate with construction activities to take advantage of potential synergies/savings was identified. The rising main installation was advanced in the 2015 Long Term Plan with the programme information available at the time.

11 This was split into two stages with stage one providing limited advanced works at

existing roads crossings at Otaihanga Road and the Te Moana Interchange in years one and two of the 2015 Long Term Plan. This sought to minimise future traffic disruption with the completion of intermediate lengths along the services corridor and Cycleways/Walkways/Bridleways (‘CWB’) adjacent to the Expressway planned for years three and four.

12 Limited early works were undertaken in 2014/2015 using surplus funds from

Te Roto Wastewater Pumping Station upgrade project. This allowed a duct to be constructed under the Expressway at the wastewater treatment plant with the main Expressway earthworks in preparation for the installation of the duplicate rising main.

ISSUES AND OPTIONS

Issues

13 The Council have been working closely with M2PP Expressway Alliance as they have refined their construction programme. It has become evident following the adoption of the 2015 Long Term Plan that significant benefits exist for advancing further sections of the duplicate rising main while the Expressway is under construction before the road is open to traffic. These include crossing the Waikanae Bridge and the section along the CWB north of the Waikanae Bridge adjacent to the 510 Retaining Wall.

14 Discussions are also underway with New Zealand Transport Agency (‘NZTA’) to

assist with funding to complete the balance of the duplicate rising main as a matter of urgency rather than returning at a later date to complete the sections along the CWB and local roads. To date, no formal offer to provide advanced funding has been made.

Existing Project Funding

15 The current budget for the duplication of the rising main is $4,082,000 and is spread out over four years as shown below:

16 This budget provided for limited advanced works in years one and two followed by the completion of the remaining length of the rising main in years three and four. The advanced works included the road crossings at Otaihanga Road and through the Te Moana Expressway interchange.

17 Any further advancement of works would require additional budget to be

allocated / sourced in early years to meet the costs of such works. 18 The Council has been working with M2PP to further detail the scoping and

construction budgets using detailed estimates and recent tender prices. The result of this work has highlighted that the construction rates for completing the rising main in the current market have increased as indicated in the priority works section below with the cost to complete the project now in excess of $4.5 million. These prices remain estimates of the costs and would need to be confirmed at the time of contract award.

19 Further work is being done to review these budgets and consider options to

mitigate cost increases to delivering the project. This may include reallocating planned pipe renewal budgets to this project to complete the work or deferral of the completion of the project to a later time when the construction market prices are more favourable after the demand for construction resources has eased afterM2PP is complete, although this has not been determined at this time.

Priorities for advancement of remaining works

20 The table below sets out the priorities for remaining works based on the benefits of each type of area the construction is occurring in. The priorities for advancement were set, based on cost and disruption minimisation while balancing the impact on rates and borrowings:

Priority Type Benefit of advancing Locations Estimate $000

21 To advance priorities three to five would require additional funding this year. This

could be achieved through either increasing the capital expenditure in the relevant years and/or deferring works in the early years and completing them in later years.

Sources of funding

22 The total wastewater capital works budget for 2015/2016 is $3.221 million which is made up of renewals and upgrades both reactive and planned across all asset types such as pipe networks, pumping stations, treatment plants and consents.

23 An examination of the 2015/2016 capital works budgets has identified the following planned projects that could be deferred with minimal risk to provide additional funding in 2015/2016 to undertake further advanced works.

24 These would provide an additional $1.5 million of funding in year one giving a total budget for the advanced works of $1.75 million which represent around 54 percent of 2015/2016 wastewater capital works budget. $1.75 million would meet the estimate of costs to complete the Waikanae Bridge approach and crossing and 510 Retaining Wall section. The budgets for the first four years of the Long Term Plan for these projects are shown in the table below:

25 The deferred works could be re programmed for completion in the following years as set out in the table below that was provided at the Council briefing on 22 October 2015.

26 This includes the following funding reprioritisations:

$700k for the Dissolved Air flotation (DAF) renewal in 2015/2016 transferred to 2016/2017 and increased for CPI to $717k

$1.13 million of annual pipe renewals from years 2015-2017 transferred into years 2017/18 and 2018/19 to give a yearly budgets of $1.26m and $818k respectively.

N617011 Page 6 of 11

$300k of wastewater network reconfigurations in 2015/2016 transferred to 2016/2017 and increased for CPI to $313k

The $4.08m funding for the Duplicate rising main redistributed in years 2015-19 as follows: $1.75m, $200k, $0, $2.1m

27 This leaves a balance of the wastewater capital works budget of $1.47 million. The remaining works are generally related to reactive pipe renewals, on-going wastewater pumping station and treatment plant renewals and upgrades and consenting works which carry a high risk should they be deferred.

28 A further $2.8 million would be required to progress priorities 4 and 5. This exceeds the remaining balance of the wastewater capital works budget of $1.47 million. To advance this work in 2015/2016, additional funding would need to be raised. Discussions with NZTA are underway to assist with funding to complete the balance of the duplicate rising main as a matter of urgency, rather than returning at a later date to complete the sections along the CWB and local roads.


29 The construction of the rising main is a substantial project requiring contract management and administrative support processes and resources. The original staging of the construction also allowed the commitment required from the Council to be managed within the existing contract delivery processes and resources related to the M2PP project.

30 Advancing the works increases the resource commitment required by Council in the short term. This can be mitigated by working with the M2PP design and procurement teams to take advantage of the Alliances larger resourcing, while maintaining value for money by procurement through competitive tendering. This also brings the benefit of improved coordination of individual works areas with the M2PP programme and mitigates contractual claims from delays or coordination costs.

31 This model where Alliance teams manage the procurement and construction of Council infrastructure, under Council guidance, has worked successfully on other works. The Council then reimburse the Alliance for the costs to complete the works.

Pumping station and rising main capacity

32 The requirement to duplicate the rising main is driven by the need to transfer additional flows from growth in Waikanae to the Paraparaumu Wastewater Treatment Plant. Failure to provide additional pumping capacity will compromise the ability of the Waikanae wastewater network to cope with wet weather flows and increase the likelihood and frequency of wet weather overflows from the system.

33 The growth projected in the earlier studies has not eventuated as rapidly as projected. In the 2006 census the population of Waikanae was 10,488 and it was projected to reach 13,933 by 2016 and ultimately 18,486 by 2061 which was the 50 year design horizon for the upgrade.

34 Based on previous flow modelling the Rauparaha pumping station would require a peak pumping capacity of 158 l/s to meet the 2 year annual recurrence interval

PREVIO

N617011 Page 7 of 11

(ARI) storm event without overflowing for the population recorded in the 2006 census.

35 The current 2015 estimate for population served by the Waikanae wastewater network is now around 11,283 and peak wet weather flows are estimated at 170 l/s which exceeds the current pumping capacity of the station.

36 Emergency storage was also constructed at the pumping station during the recent upgrades and along with storage in the network provides some buffering of the peak wet weather flows at the station of just over four hours at current expected flows.

37 An upgrade of the power supply at the Rauparaha pumping station would provide the capacity to run more than one of the four pumps at a time. Running two pumps together would increase flows to around 160 l/s while running three would give 175 l/s. This does however increase the pressure in the rising main significantly, bringing it closer to its maximum rated operating pressure. Running the pumping station in this manner would increase the risk of a failure in the main.

38 Further emergency storage exists at the Waikanae ponds pumping station upstream of the Rauparaha pumping station and is used currently when the Rauparaha station reaches high levels.

39 Future growth will continue to reduce the effectiveness of the emergency storage and the network to buffer wet weather flows and prevent overflowing from the network in the 2 year ARI storm event.

40 The duplication of the rising main and upgrading of the power supply will allow multiple pumps to be used concurrently to increase the flows from the pumping station to the 50 year design population without increasing the pressure in or risk of failure of the existing rising main.

41 Further modelling is currently underway to assess the current performance of the Waikanae wastewater network and the Rauparaha pumping station at its current stage of upgrade and the results are expected by the end of the year.


Option 1 - Maintain existing programme

42 The existing programme would see the completion of Otaihanga Road crossing and Te Moana Interchange in the current year with the installation of other sections of the rising main being undertaken in the future. This would remove the need to excavate recently constructed local road surfaces and the associated traffic disruption.

43 Challenging construction issues would need to be resolved to complete the Waikanae Bridge Crossing across in a live Expressway. The installation of the pipe through the 510 Retaining Wall section north of the Waikanae Bridge would be difficult post Expressway construction because of the constraints in this area. Issues such as significant traffic management, the need for alternative construction methods and the potential for additional consenting would introduce further increases in the procurement, installation methodology and construction costs.

44 The completion of the rising main along the balance of the CWB adjacent to the Expressway and along Te Moana Road to Rauparaha pumping station would still need to be completed at a later date. This would require the disruption at these locations.

45 While there are no changes to current proposed Long Term Plan programme a contingency for additional costs to complete the project within the proposed four year timeframe should be held in reserve until contract prices are confirmed and construction complete. This could be achieved by reallocating deferred pipe renewal budgets to this project or deferral of the completion of the project at a later time when the construction market prices may be more favourable.

Option 2 - Advance the Waikanae Bridge Crossing and the 510 Retaining Wall sections

46 It has become evident that significant benefits exist for advancing the Waikanae Bridge Crossing and the 510 Retaining Wall Sections of the duplicate rising main while the Expressway is under construction and before the road is open to traffic.

47 This advanced programme would see the completion of the Otaihanga Road and

Waikanae crossings, 510 Retaining Wall section and the Te Moana Interchange in the current year with the installation of other sections of the rising main being undertaken in the future.

48 This would take advantage of the construction efficiencies from installing the rising main with the Expressway works. This is particularly relevant at the Waikanae Bridge and 510 Retaining Wall sections where retrospective installation would attract addition costs to manage traffic and alternative construction techniques.

49 Furthermore, it would eliminate the need to excavate recently constructed local road surfaces at Otaihanga and complete the crossing of the Te Moana Interchange.

50 The completion of the rising main along the balance of the CWB adjacent to the Expressway and along Te Moana Road to Rauparaha pumping station would still need to be completed at a later date. This would require the disruption of the use of these locations.

51 This requires the deferral of $1.5 million of existing projects proposed in year one of the Long Term Plan.

52 A contingency for additional costs to complete the project within the proposed 4 year timeframe should be held in reserve until contract prices are confirmed. This could be achieved by reallocating deferred pipe renewal budgets to this project or deferral of the completion of the project at a later time when the construction market prices are more favourable.

Option 3 Defer the installation of the rising main

53 Deferral of the completion of the rising main either in whole or in part will reduce the ability of the wastewater network in Waikanae to cope with wet weather flows increasing the likelihood and frequency of wet weather overflows as the population grows.

The preferred option is option two

54 The advancement of the construction of the Waikanae Bridge Crossing and the 510 Retaining Wall sections of the WDRM in 2015/2016 in conjunction with the construction of the M2PP Expressway.

55 Funding for option two is from the re-prioritisation of three existing wastewater capital projects:

$700k for the Dissolved Air flotation (DAF) renewal in 2015/2016 to 2016/2017

$1.13 million of annual pipe renewals from years 2015-2017 and spread over 2017-2019

$300k of wastewater network reconfigurations in 2015/2016 to 2016/2017

56 The results of the tendering process are expected by the end of the year and will confirm the projected costs to complete the rising main within the four year programme against the original budget.

57 A contingency for additional costs to complete the project within the proposed four year timeframe should be held reserve until contract prices are confirmed. This could be achieved by holding the deferred pipe renewal budgets or deferral of the completion of the project at a later time when the construction market prices are more favourable.

58 The results of the wastewater modelling will further inform the decision to proceed with the completion of the project in the four year time frame or provide updated evidence to support further deferral of the completion of the project to a later date when potentially construction rates are more favourable.

CONSIDERATIONS

Policy considerations

SIGNIFICANCE & ENGAGEMENT POLICY 2014

59 The re-prioritisation of wastewater capital spending to use $1.5 million of existing budget in 2015/2016 and deferral $1.5 million of existing projects was reviewed against the significance policy and considered to have a low level of significance.

Legal considerations

60 There are no statutory requirements related to this proposal.

Financial considerations

61 The preferred option is considered to be prudent management of capital investment funding that:

Minimises the cost of the project by coordinating works with the construction of the M2PP Expressway at critical sections along the alignment and staging completion of the balance of the rising main over four years;

Manages the advancement within the 2015 Long Term Plan wastewater capital budgets;

Tāngata whenua considerations

62 There are no known issues for consideration relating to Iwi with the re-prioritisation of these projects.

Consultation already undertaken

No formal consultation has been undertaken to date.

Engagement planning

63 The staging of the construction of the WDRM and projects now proposed for deferral were set out in the 2015 Long Term Plan which was consulted on prior to adoption.

64 The re-prioritisation of the wastewater capital budgets in year one of the plan and deferral of projects to later years does not impact of the level of service to the community and it is considered an engagement plan is not needed to implement this decision. A media release to advise of the community of the results achieved by working with the Alliance to deliver the advanced works may assist in “informing the community” about progress on the long term plan.

Publicity

65 The approach to managing the staging of the construction of the WDRM was publicised in the 2015 Long Term Plan.

RECOMMENDATIONS

66 That the Corporate Business Committee accept the recommendation to proceed with option two.

67 Approve the re-prioritisation of wastewater capital projects funding as follows:

$700k for the Dissolved Air flotation (DAF) renewal in 2015/2016 transferred to 2016/2017 and increased for CPI to $717k

$1.13 million of annual pipe renewals from years 2015-2017 transferred into years 2017/18 and 2018/19 to give yearly budgets of $1.26m and $818k respectively.

$300k of wastewater network reconfigurations in 2015/2016 transferred to 2016/2017 and increased for CPI to $313k

The $4.08m funding for the Duplicate rising main redistributed across years 2015-19 as follows: $1.75m, $200k, $100k, $2.0m

Draft NZTA– KCDC MOU Version 01, April 06 2016

Page 1 of 13

APPENDIX 2

Memorandum of Understanding Wastewater Pump Station WSP009 Rising Main

between the

New Zealand Transport Agency (NZTA) and the

Kapiti Coast District Council (KCDC)

(“the Parties”)

1. Purpose

The purpose of this Memorandum of Understanding (“MOU”) is to record the guidelines for collaboration between the Parties for the delivery and resourcing necessary to achieve the shared, common goal of the design and installation of the Wastewater Pump Station WSP009 Rising Main (“the Project”).

2. Background

The Mackays to Peka Peka (M2PP) Alliance is a formed entity between New Zealand Transport Agency, The Fletcher Construction Company Limited, Higgins Contractors Limited and Beca Limited. The M2PP Alliance is responsible for the design and construction of NZTA’s SH1 Mackays to Peka Peka Expressway.

KCDC is a local district council within the meaning of the Local Government Act 2002 (“LGA02”). KCDC is responsible for implementing and managing the Council’s 20 year Long Term Plan

Kapiti Coast District Council have allowed in their Long Term Council Community Plan (LTCCP) for the incremental construction of approximately 3.5km length of sewer rising main over the next 3 years. The new rising main will be provided from the Wastewater Pump Station WSP009 at Te Moana Road to the Paraparaumu Wastewater Treatment Plant (south of Otaihanga Landfill).

The preferred alignment of the Wastewater Pump Station WSP009 Rising Main has been confirmed as along the new Mackays to Peka Peka Expressway alignment, predominately within the Cycleway, Walkway and Bridleway path.

The CWB is approximately 18km long and formed to a width of 3m with a 1m grassed verge for equestrians. In rural parts of the district the CWB is constructed from an unbound “Kapiti Blue” rock.

As well as providing for non-motorised road users, the CWB acts as a utility corridor and provides for maintenance access to landscaping and stormwater assets.


Page 2 of 13

3. WSP009 Sewer Rising Main - Separable Portion A

Separable Portion A includes sections of the sewer rising main that is committed to be installed i.e. below local roads, below expressway, Waikanae River Bridge and 510 retaining wall. KCDC currently have $1.75m budget that has been brought forward from future financial years.

M2PP will deliver the scheme design (including consents) and the installation of four sections of Wastewater Pump Station WSP009 Rising Main during the construction of the Mackays to Peka Peka Expressway.

These sections coincide with the following areas in conjunction with utility diversions and expressway construction:

Delivery of scheme design, drawings & consents

M2PP Preliminary and General including but not limited to tender processing, KCDC liaison, design input & project management/site supervision

Sector 440 - Chainage 700 to 818 - Otaihanga Road crossing. (Completed)

Sectors 460/470/480 - Chainage 1960 to 2680 – Construction of Waikanae River Bridge crossing to minimise cost and disruption post bridge completion. Includes wastewater rising main to be sleeved from bridge abutments to cycleways.

Sectors 480/510 - Chainage 2925 to 3025 - The Sector 510 retaining wall – which is a particularly constrained section of the alignment with sensitive stakeholder relationships.

Sector 510 - Chainage 3310 to 3588 Te Moana Road – Section of wastewater rising main crossing under on and off ramps and bridge.

4. WSP009 Sewer Rising Main - Separable Portion B

Subject to funding from NZTA, M2PP will deliver the remaining sections of Wastewater Pump Station WSP009 Rising Main during the construction of the Mackays to Peka Peka Expressway.

Future sections out with the expressway designation i.e. Connection to WWTP and Pump Station will be designed and delivered at a later stage by KCDC.

Sector 430 - Chainage 0 to 700 – Installation from existing sleeve to Otaihanga Road.

Sectors 460 - Chainage 818 to 1960 – Connecting Otaihanga Road to Waikanae River Bridge (South abutment)

Sectors 480/510 - Chainage 2680 to 2925) – Connecting Waikanae River Bridge (North abutment) to 510 retaining wall

Sector 510 - Chainage 3025 to 3310 – Connecting 510 retaining wall to Ta Moana Rd section.

The Parties have decided to formalise their working relationship by entering into this MOU.


Page 3 of 13

5. Statutory Framework

The parties acknowledge that they each have statutory responsibilities, powers and duties, including under the Government Roading Powers Act 1989, the Resource Management Act 1991, the LTMA and the LGA02. While the parties have committed to work together constructively in relation to the matters addressed by this MOU, it is recognised and agreed that this MOU in no way fetters the parties in relation to those statutory responsibilities, powers and duties.

When any approvals or consents are required under this MOU a party will not be acting unreasonably or arbitrarily if it declines its consent or approval, or imposes conditions on any such consent or approval, on the grounds of its statutory responsibilities, powers and duties, provided such grounds are specified in writing at the time.

The parties will not claim from each other any compensation, loss or damage under this agreement if, as a result of the other party having exercised in good faith, its statutory duties, a party is affected in anyway whatsoever.

6. Desired Outcomes

The Parties seek to accelerate the design and installation of the Wastewater Pump Station WSP009 Rising Main within sections of the Mackays to Peka Peka Expressway alignment, avoiding unnecessary costs or disruption to either party. The parties understand that the delivery will be staged in conjunction with the expressway construction.

7. Understanding

The Parties agree to work constructively and collaboratively in relation to the implementation of this MOU and the Project.

KCDC will be responsible for:

Reviewing the detailed designs with input from Aurecon for the Wastewater Pump Station WSP009 Rising Main within the expressway alignment;

Completion of the wastewater rising main hydraulic analysis from Aurecon and confirmation of the air and scour valve locations;

Approving final design drawings to be issued for construction by January 2016;

In conjunction with M2PP Alliance, securing the necessary resource consents, licences and other approvals necessary to enable construction of the wastewater rising main by March 2016;

Leading the collaborative development of project communications messaging with the the Mackays to Peka Peka (“M2PP”) Alliance (“M2PP ALLIANCE”);

M2PP Alliance will be responsible for:

Design and delivery of drawings, details and sections for the Wastewater Pump Station WSP009 Rising Main within the expressway designation. Excluding from a) the Paraparaumu WWTP to the expressway designation and b) from the Wastewater Pump Station WSP009 to the expressway designation;

Preparation and execution of tender documents for the entire scheme for separable portions A & B but excluding WWTP and Pump Station connections..

Preparation and submissions of all consents and permits required on behalf of KCDC for Osbournes Drain


Page 4 of 13

Any consents/permits required during the physical works for the remainder of the sewer rising main will come under the existing M2PP consents/permits for the expressway project;

Procurement of the 400mm & 630mm PE100 SDR17 pipe including all associated fittings and components;

Management, delivery, and commissioning of physical works associated with the installation of the sewer rising main for separable portions A & B;

Delivery of quality documentation and red-line as-built drawings as identified in the design specifications;

Capturing quality assurance documentation.

Initiating and fronting communication with the media.

The Parties agree that M2PP Alliance is an appropriate mechanism to use for delivery of the physical works on behalf of KCDC. The key risks and opportunities

faster initiation by using the existing contract for mobilisation planning in parallel with seeking sub-contractor prices;

faster procurement of the physical works resulting from use of existing preferred supplier arrangements;

greater flexibility within an Alliance to respond to unforeseen changes associated with consenting delays or archaeological finds during construction; and

availability of established community and Iwi engagement team to respond to day to day queries related to construction activities.

8. Key Risks & Opportunities

Risks

KCDC intend to complete the rising main by the end of the 2017/18 financial year (i.e. July 18) at least 18 months after the CWB is opened. It is expected that construction of the rising main would involve temporary closure of sections of the CWB for several months at a time. There is a risk that path users and the community are critical that this work was not undertaken at the same time as the expressway works. The community are unlikely to distinguish between the Transport Agency, KCDC or the M2PP Alliance and in effect the participants of M2PP Alliance share this reputational risk.

Construction of the rising main after the CWB is opened will be more costly (approx. $500k) for KCDC than if completed beforehand. The additional cost associated with later works would be associated with re-instatement of the CWB and associated landscaping. Traffic management would also be required if the rising main were constructed after opening.

Opportunities

Constructing the rising main during or before the CWB is delivered will avoid the need to reinstate landscaping, reinstate environmental controls (sector 480/510), CWB pavement and surfacing resulting in a cost saving opportunity for the Kapiti Coast District Council and mitigating the above reputational risk.

Procurement of PE pipes by M2PP prior to 10% cost increase early in 2016.

mailto:[email protected]







Page 7 of 13

The Parties acknowledge that the M2PP Alliance will invoice KCDC directly on a monthly basis for works associated with the Wastewater Pump Station WSP009 Rising Main in accordance with the overall commercial approach outlined below.

The basis of the commercial arrangement is outlined as follows and will be finalised via an exchange of letters as part of the scope, risk register, risk allocation and cost finalisation:

a) A Measure & Value approach will be adopted with M2PP Alliance Project

Management and On-costs applied. The basis comprises:

Measure and Value Contract for sub-contract suppliers.

Competitively secured rates from established Alliance sub-contractor suppliers.

Rates developed for any Alliance self-perform scope, e.g. if pavement surfacing, PE welding or trenching is completed via Higgins (on an open book basis)

Preliminary & General costs will be quantified, priced and recoverable for direct project management & site supervision.

A Risk Register will be developed, for agreement by the Control Group that will identify the owner of each risk and will be used to produce a KCDC Contingency sum that will be managed by the Control Group.

An agreed M2PP Alliance Construction margin of 10% is to be applied on the material supply and installation items.

An agreed M2PP Alliance Design margin of 36% is to be applied to all design and consenting items.

A defects liability period of 12 months.

b) The Parties acknowledge that additional cost, or time relating to design, consenting, expressway construction delays or archaeological finds remain the risk of KCDC.

c) The Parties acknowledge that commercial consideration is required around the risks of quality control, defect management, final handover to KCDC and contractor liabilities/insurances

14. Funding

As Part of the LTCCP, KCDC have a staged budget of $4,100,000.

KCDC budget also includes allowance at either end of the pipeline for connecting to the wastewater treatment plant and pump station. These works are outside the designation and away from local roads.
