ITEM 9.8      SF1391            190810         Response from Political Parties to Funding Request

 

AUTHOR/ENQUIRIES:     Rhonda Hoban, Councillor         

 

Summary:

 

In the run up to the election, Council has had some success in securing funding promises from both the Coalition and Labor.  These relate to the off stream dam and also the repair of Riverside Drive.  So with most bases covered I look forward to either Labor or the Coalition making good on their promises.

 

 

Recommendation:

 

That the information concerning funding promises by the Coalition and Labor be received.

 

 

 

Background

 

At the last meeting in response to my Mayoral Minute it was resolved:

 

“That as the cost of securing our water supply will be a major issue for Nambucca Shire’s voting residents, Council write to all major political parties and ask who will commit to matching the State Government’s funding for the Off Stream storage dam, to achieve a three way partnership between State, Federal and Local Government for what is a major infrastructure project”.

 

Council has now received responses from all three major parties.

 

The Greens advised:

 

“…This is a complex issue and we agree that secure water supplies need to be ensured before further development takes place.  As we don't know the full details of your request that was denied, we cannot give it unconditional support and sadly, time does not permit for us to study the documentation prior to the election.

 

We would like to assure you that this is an issue that Dominic would address should he be elected.  We understand the difficulties under which local Governments must work, with rate capping and so forth and would work with you to find a solution.”

 

The Coalition, through Cowper MP Luke Hartsuyker advised:

 

Last week, The Leader of The Nationals Warren Truss and I met with the Nambucca Shire Council to discuss the details of this project.

 

The Coalition has a $500 million water security fund which will target areas where water supply is a real issue for local communities.

 

Nambucca Shire Council has indicated they will apply for the full $18 million if the Coalition is elected to Government.

 

This is a vital piece of the infrastructure for the Nambucca Valley. It is essential to the sustainability of the shire and the future development of the region.

 

Only the Coalition has the capacity to deliver the total amount required for this project. The project has my full support.”

 

Yesterday, on behalf of the Labor Party, Senator Michael Forshaw and Labor Candidate for Cowper Paul Sekfy announced a re-elected Gillard Labor Government would,

 

“…provide $10 million to Council for the construction of the off river water storage”

 

The Federal funding is dependent on the Nambucca Shire Council submitting a detailed project plan, and on relevant planning and environmental approvals.

 

I should also say that the Luke Hartsuyker on behalf of the Coalition pledged $5.5m for the repair of Riverside Drive being the work identified by GHD to stabilise the road and prevent it from slipping into the river and secondly the stabilisation of the “top side” land slips.

 

So with most bases covered I look forward to either Labor or the Coalition making good on their promises.

General Manager's Report

ITEM 9.9      RF275              190810         Repair of Bellingen Road

 

AUTHOR/ENQUIRIES:     Michael Coulter, General Manager         

 

Summary:

 

The RTA considers that the engagement of a consultant by Council to complete the survey and detailed design for the restoration of the northern section of the Bellingen Road should be undertaken immediately and that a Value Management process be utilised to make a recommendation concerning the southern damaged section of the road.

 

The proposed approach by the RTA is agreed.

 

In relation to the proposed Value Management process to determine a preferred option for the southern section of the road, it is recommended that Council be represented by at least the Mayor and Acting Director Engineering Services.

 

Coffey and Partners are recommended to complete the detailed survey and design at a cost of $66,590.90 excluding GST.  This needs to be confirmed by the issue of a schedule of works by the RTA.

 

Given the involvement of GHD in the investigations and options report, it is recommended that they be offered the role of facilitator for the Value Management Workshop and that it be convened within 2 months.

 

 

Recommendation:

 

1        That Council advise the RTA that it agrees with the engagement of a consultant to complete the survey and detailed design for the restoration of the northern section of the road and for a Value Management process to be undertaken in relation to the southern damaged section.

 

2        That Council recommend to the RTA that Coffey and Partners be appointed to undertake the detailed survey and design for the repair of the northern section of damaged road at a cost of $66,590.90 excluding GST.

 

3        That the RTA be advised that the Council will be represented at the Value Management workshop by at least the Mayor and Acting Director Engineering Services with the final composition of the workshop group to be determined by the RTA.

 

4        That Council recommend to the RTA that GHD be offered the role of facilitator for the Value Management process and that it be convened within 2 months.  In the event that GHD are unavailable that the RTA appoint another facilitator.

 

 

OPTIONS:

 

The seven potential options for the road are identified in the GHD report and in the discussion.  About 17 months have already elapsed since the destruction of the two sections of the road in cyclonic wind and rain in late March 2009.  If an alternative option is preferred, consideration needs to be given to the time it will take to implement as further damage to the road will leave residents and businesses isolated and will also further damage the environment.

 

 

DISCUSSION:

 

In September 2009 Council received funding from the Roads and Traffic Authority under Natural Disaster Funding for the preparation of an options report on the repair of the Bellingen Road.  In December 2009 geotechnical consultants GHD were commissioned to undertake an investigation and prepare an options report.  The draft report was completed in April 2010 and there was a briefing of Mayors and Council staff at Bellingen Shire Council on 29 April 2010.  A further briefing of the most affected residents from the Spicketts Creek valley was held at the Brierfield Hall on 27 May 2010.  A briefing for the general community was conducted at the Bowraville Theatre on 4 August 2010.

 

The GHD report outlined 7 options for the future of the road as follows:

 

1        Repair and restore both the northern and southern damaged sections

2        Repair and restore only the northern section and close the southern section after rehabilitating the damage

3        As per option 2 but maintain the southern section of road for service vehicles only (NPWS, RFS,    Forestry etc)

4        Close both sections and compulsorily acquire Spicketts Creek properties (plus rehabilitation of       damage)

5        Build an alternative route being Kenniacle Creek, Blairs Road, Rickerbys Road to Kalang Road

6        Build an alternative route for the southern section being Tombstone trail through the nature   reserve to Valley Valley trail

7.       Build an alternative route for the southern section through the nature reserve to Noonanie southern  access track.

 

Following the two workshops and advice from the consultants, the realistic options were reduced to options 1 to 4.

 

The RTA now advise that the cost of acquiring the affected properties in option 4 would be similar to repairing and restoring the northern section of the road ($8m) and hence believe that option 4 can be deleted as a viable option.

 

This leaves options 1 to 3 which the RTA believes should be the subject of a Value Management assessment to identify a preferred option.  As the restoration of the northern section is a common requirement for all three remaining options then, with the Councils’ agreement, the RTA considers that the engagement of a consultant by Council to complete the survey and detailed design for the restoration of the northern section of the road should be undertaken immediately.

 

This will facilitate the earliest delivery of the restoration of the northern section and restore reliable access to the residents of Spicketts Valley.  The Value Management process can then continue to further refine and identify the final preferred option for the southern section.

 

The proposed approach by the RTA is agreed.  With the elimination of the compulsory acquisition of the Spicketts Creek properties, the repair and restoration of the northern damaged section is a common factor in the three remaining options.

 

There is also some urgency in attending to the repair of the northern section.  It is currently unsafe to move a large grader or truck over the damaged northern section of road to undertake maintenance grading in Spicketts Creek.  Of greater concern is that a severe weather event may result in additional land slips rendering the road completely impassable.  This would leave residents and in some cases businesses, isolated without any road access.

 

In relation to the proposed Value Management process to determine a preferred option for the southern section of the road, it is recommended that Council be represented by at least the Mayor and Acting Director Engineering Services, with the final composition of the workshop group to be determined by the Roads and Traffic Authority.  Given the involvement of GHD in the investigations and options report, it should also be recommended to the RTA that GHD be offered the role of facilitator for the Value Management Workshop and that it be convened within 2 months.

 

Council has sought quotations from three reputable and local consultancies for the detailed survey and design to repair the northern section of the Bellingen Road.  Subsequently one of the three consultancies declined to provide a quotation.  A confidential circularised document providing a comparison of the two consultancies which submitted prices is attached.  On the basis of the comparison it is recommended that Coffey and Partners be recommended to the RTA for the issue of a schedule of works so that the design can proceed.  The quotation from Coffey and Partners to complete the detailed survey and design is $66,590.90 excluding GST.

 

 

CONSULTATION:

 

There has been consultation with Council’s Acting Director Engineering Services, the Mayor, the RTA, Bellingen Shire Council and some property owners.

 

 

SUSTAINABILITY ASSESSMENT:

 

Environment

 

The destruction of the road is resulting in additional downstream sedimentation.  Access into the area is also important for management of the Nature Reserve and bushfire control.

 

Social

 

There are important social issues for the residents of the Spicketts Creek valley.  They have gone from having access in 2 directions (north and south) to having only one access to the north, with that access having been damaged by land slips.  The northern access is currently unsuited to large trucks and Council’s Overseer has deemed it unsafe for use by Council’s graders and trucks.  There are also broader social issues in relation to the loss of direct access between Bowraville and Bellingen.

 

Economic

 

The Bellingen Road has been a tourist route.  The final decision in relation to the southern section of the road will have economic implications for both the Nambucca and Bellingen communities, particularly in relation to its affect on tourism.

 

Risk

 

There are numerous risks.  The repair of the road will pose construction risks.  There are also significant risks for Council should there be further damage to the northern section of the road and the residents have no road access.

 

 

FINANCIAL IMPLICATIONS:

 

Direct and indirect impact on current and future budgets

 

The design and construction of the road is to be funded under the Natural Disaster funding arrangements.  The repair of the Bellingen Road should have no additional impact on Council’s budget.

 

Source of fund and any variance to working funds

 

There should be no additional impact on Council’s working funds.

Director of Engineering Services Report

ITEM 11.2    SF768              190810         Refurbishment of Congarinni North Bridge

 

AUTHOR/ENQUIRIES:     Noel Chapman, Acting Director Engineering Services         

 

Summary:

 

The contractor has commenced work on refurbishment of Congarinni North Bridge.  The contract provides for replacements of girders on three spans and a new concrete deck on all eight spans. 

 

The majority of the deck has now been removed.  Inspection of the girders on spans four to eight has revealed significant deterioration including splitting and white ant infestation.

 

 

Recommendation:

 

That, with the contract for the refurbishment of the Congarinni North Bridge, Council:

 

1        Replace the girders on spans four to eight with concrete girders

 

2        Approve a variation to the contract

 

3        Allocate the additional $199,650 + GST to incorporate concrete girders.

 

 

OPTIONS:

 

1        Leave the existing girders.  Has potential for failure and increased long term costs.

2        Replace the timber girders with new timber girders.  This leaves the bridge with a mixed service life.

3        Replace the timber girders with concrete as recommended

 

 

DISCUSSION:

 

During removal of the existing timber decking the contractor has expressed concern with the condition of the timber girders on the five spans to remain.  Council’s Bridge Supervisor inspected these girders and found significant splitting and white ant activity.  He reported that he would have concern putting new concrete decking on these girders.

 

A number of options have been considered.

 

Firstly continuing with the project in accordance with the contract as accepted.  This option would increase the static loading on the girders with the possibility of catastrophic failure.  In any event the condition of the girders gives a much shorter service life, expensive replacement and further closure of the bridge.  A lower load limit would be imposed. 

 

The second option is to install new timber girders.  While this option would remove the risk of girder failure the service life would be less than the rest of the bridge with concrete girders.  This would result in future removal of the concrete deck to replace the girders, a very expensive exercise.  The estimated cost of this option is $181,000 (day labour) plus future replacement costs.

 

The third and preferred option is to vary the existing contract to replace the timber with concrete girders.  This would remove all risk with the benefit that the entire bridge would have the same service life.  the contractor has advised that the can incorporate the variation with no delay and has provided a quotation of $199,650 + GST to undertake the additional work.

 

Removal of the load limit would be possible.

 

 


CONSULTATION:

 

·              Bridge Supervisor

·              Senior Overseer

·              General Manager

·              Contractor

·              Manager Assets

 

 

SUSTAINABILITY ASSESSMENT:

 

Environment

 

There are no issues as a result of this report.

 

Social

 

Retention of the existing girders would result in further closure of the bridge and disruption to local traffic.

 

Economic

 

Any further failure or closure would impact on transportation costs.

 

Risk

 

Retaining the existing girders could result in a major failure and serious injury or loss of life.  Council could be deemed negligent knowing the poor condition of the existing girders.

 

 

FINANCIAL IMPLICATIONS:

 

Direct and indirect impact on current and future budgets

 

The cost of the current work being undertaken by the contractor is $506,300.  Options 2 and 3 will add a further and unbudgeted $181,000 or $199,650 + GST respectively.

 

Option 1 will impact on a future budget due to a relatively short service life.  This cost would be inflated due to the need to remove the concrete deck.  There is a possibility of penalties should failure occur.

 

Source of fund and any variance to working funds

 

Additional funds to be allocated from working funds or other adopted deferred projects.
