Notice of Motion

ITEM 5 .1     SF1714            300812         Signage at Southern Entrance to Macksville

 

AUTHOR/ENQUIRIES:     Elaine South, Councillor         

 

Summary:

 

I would like to submit a late notice of motion re signage at the southern approach to Macksville, preferable in the vicinity of the golf course in the 50 klm zone to indicate the Macksville town/shopping centre/ Central Business District (whatever the distance is), is the centre of town and the gateway to the Nambucca Valley. I have had discussions with businesses in town who have genuine concerns as to loss of business due to the north travelling public not being aware of the Macksville shopping centre, thus not bringing business and people into the town area. We now have a beautiful riverside park area, that the travelling public can use, unique small businesses and country hospitality. All of which needs to be promoted to encourage travellers and holidayers into the town centre. I have noticed other towns have signage, quite large and obvious, to draw attention to travellers. As the tourist dollar is a very large component of local income I would like this to be put forward for recommendation.

 

 

Recommendation:

 

That Council seek to establish signage at the southern approach to Macksville facing north, to advise the travelling public that the Macksville Town Centre is further north (whatever distance), and to seek funding/costings for appropriate signage.

General Manager's Report

ITEM 9 .10   RF275              300812         Bellingen-Bowraville Road

 

AUTHOR/ENQUIRIES:     Michael Coulter, General Manager         

 

Summary:

 

Roads and Maritime Services has advised Council that the restoration of the southern section of Bellingen - Bowraville Road Road is not supported by Roads and Maritime Services (RMS) unless work is undertaken to mitigate the risk of future land slips simultaneously.

 

The funding which Council would need to source to undertake the specified mitigation work would run to many millions of dollars.  The Roads and Maritime Services are aware that the cost of the mitigation works is well beyond Council’s budget.  The only potential funding source would seem to be grant funding from the Commonwealth Government.  There are no known Commonwealth grant programs available for such mitigation work.

 

The response is unsatisfactory as it is contrary to the adopted Natural Disaster funding arrangements and is also contrary to the findings of a Value Management Workshop conducted on 14 December 2010.  The determination of the Value Management Workshop that the road should be reinstated was also supported by the Member for Oxley (then in opposition) in a media release issued in January 2011 (attached).

 

 

Recommendation:

 

1        That Council forward the letter from the Roads and Maritime Services to the Bowraville and District Chamber of Commerce; the Bellingen Chamber of Commerce; Bellingen Shire Council; the Bellingen (Coffs Coast) Tourism Association; Nambucca Valley Tourism; as well as the residents of the Spicketts Creek area located with the Shire of Nambucca seeking their comments and suggestions.

 

2        That the matter be reported to a Council meeting in October 2012 including any comments and suggestions received from the groups and people listed in recommendation 1.

 

 

OPTIONS:

 

There are a range of options available to Council.  It could accept the proposal put by Roads and Maritime Services.  It could make representations to its local State member and/or to the Minister for Roads and Maritime Services.  Council has already many representations seeking the reinstatement of the road.

 

DISCUSSION:

 

The Bellingen to Bowraville Road was originally constructed as a bridle trail in the 1880’s to link the two towns.  It became a road around 1901.  The road was originally constructed for horse traffic and was progressively widened in the 1900s to cater for larger motor vehicle traffic.

 

During major rain events in February and March 2009, two zones of the Bellingen-Bowraville Road suffered major damage due to landslides and related scouring of embankments.  The road has been closed to traffic ever since these events.  The southern section of the landslide damage in the Shire of Nambucca encompassed Bowra Mountain and Bowraville Nature Reserve and was impacted by 32 landslides within 3.5km.  The road is either buried or completely blocked at many locations.

 

The northern zone of landslide damage occurred near Dyers Mountain above the southern section of Spicketts Creek where up to 10 landslides occurred within a 0.8km.  Roads and Maritime Services are spending $10m on the repair and restoration of this section of road.

 

In between the two landslide damage zones (northern and southern) in the Spicketts Creek Valley are a number of properties within the Shire of Nambucca.  However their only access is from the Bellingen Shire.

 

Council has now received the attached letter from Roads and Maritime Services advising that the restoration of the southern section of road is not supported by Roads and Maritime Services (RMS) unless work is undertaken to mitigate the risk of future land slips simultaneously.  Council would need to source the funding for this mitigation work which would need to consider:

 

·      Drainage upgrades at all gullies, including engineered “causeways” to better control the flow of water over the road.

·      Drainage capacity upgrades with improved down slope scour protection arrangements.

·      All drains near gullies would need to be lined.

·      Road shoulders in locations prone to scour would need to be “armoured”.

·      Undertaking upslope improvement works including tree cleaning and a range of rock bolting, soil nailing and shotcrete works.

 

The funding which Council would need to source to undertake the specified mitigation work would run to many millions of dollars.  The Roads and Maritime Services are aware that the cost of the mitigation works is well beyond Council’s budget.  The only potential funding source would seem to be grant funding from the Commonwealth Government.  There are no known Commonwealth grant programs available for such mitigation work.

 

The response is unsatisfactory as it is contrary to the adopted Natural Disaster funding arrangements and is also contrary to the findings of a Value Management Workshop conducted on 14 December 2010.  The determination of the Value Management Workshop that the road should be reinstated was also supported by the Member for Oxley (then in Opposition) in a media release issued in January 2011 (attached).

 

The Natural Disaster funding arrangements are set out on the RMS website.

 

The flood/storm event which caused the damage to the Bellingen/Bowraville Road was a declared Natural Disaster.

 

The funding arrangements provide that for a Natural Disaster assistance will be provided for the reinstatement of local roads and bridges at 75% of the assessed cost up to $116,000 and 100% thereafter.

 

The funding arrangements state that;

 

“The fundamental principle is the restoration or replacement of roads and bridges, damaged as a direct result of an eligible event, to the equivalent of their pre-damage standard or service level”.

 

Given the cost of reinstating the road, the Council also agreed to the conduct of a Value Management Workshop organised by Roads and Maritime Services.  This was held on 14 December 2010.  The Value Management Workshop determined that the best option was to restore both the Northern and Southern zones of damage to the road (Option 1).  The advantages and disadvantages of this option were listed as:

 

“Advantages

·      All weather road is re-opened for residents and through traffic

·      Emergency access and escape for residents in both directions

·      Restores links to key fire trails

·      Provides the previous connectivity links (cultural, social, economic etc)

·      Provides future development, growth and tourism potential

·      Preferred option of the community (community questionnaires)

·      Greater economic advantage to the region than Options 2, 3 and 4.

 

Disadvantages

·      Technically difficult

·      Long time to carry out works

·      Major disruptions to traffic in the northern zone during construction

·      Expensive”

 

A copy of the Value Management Workshop report is circularised for the information of Councillors.

It is proposed that the RMS letter (attached) be circulated to all interested stakeholders and Spicketts Creek residents for comment and following receipt of those comments Council then formally consider its response to the RMS.

The stakeholder groups to be consulted will be the Bowraville and District Chamber of Commerce; the Bellingen Chamber of Commerce; Bellingen Shire Council; the Bellingen (Coffs Coast) Tourism Association; and Nambucca Valley Tourism.

 

 

CONSULTATION:

 

There has been consultation with the Mayor who has had an integral role in lobbying for the reinstatement of the Bellingen/Bowraville Road.

 

 

SUSTAINABILITY ASSESSMENT:

 

Environment

 

Regardless of whether the road is replaced or not, environmental works need to be undertaken to control siltation and weeds.  The commitment from the RMS for an expenditure of “up to $1 million is of concern.  Besides being ill defined it also suggests that nearly two (2) years after the Value Management Workshop was conducted, there is no costed program of works for environmental rehabilitation.

 

Social

 

The social implications of the removal of this access between the Nambucca and Bellingen communities is been well documented in the Value Management report.

 

Economic

 

The economic implications, particularly for tourism, in the removal of this road are well documented in the Value Management Workshop report.

 

Risk

 

There are risks in both opening the road and also in not reinstating the road.  These are addressed in the Value Management report.

 

It is also of concern that the RMS have determined that the southern section of the road is, “not considered an essential public asset” and therefore not eligible for federal natural disaster assistance.  This is a new criterion, not mentioned in the published Natural Disaster funding arrangements.  Other Councils should be concerned that the RMS may, depending on replacement cost, deem that a public asset is not “essential”.

 

FINANCIAL IMPLICATIONS:

 

Direct and indirect impact on current and future budgets

 

Council cannot afford the cost of the nominated mitigation works.  A voluntary local government boundary adjustment to locate the “isolated” Spickett’s Creek property owners with the Shire of Bellingen will result in the loss of rate revenue.  The loss of rate revenue would be offset to some extent by a reduction in expenses associated with road grading and any other costs incurred in the residents’ use of Shire facilities.


 

Source of fund and any variance to working funds

 

There are no implications for working funds.

General Manager's Report

ITEM 9 .12   SF600              300812         Gateway Determination - Reclassification of Community Land Bowraville Race Course

 

AUTHOR/ENQUIRIES:     Grant Nelson, Strategic Planner         

 

Summary:

 

The purpose of this report is to advise Council of the recent gateway determination for the proposed reclassification of Community Land at Bowraville.

 

 

Recommendation:

 

1          That Council note the gateway determination to proceed with the reclassification of Lot 3 DP 593774 and Lot 4 DP593774, Rodeo Drive, Bowraville from community to operational land.

 

2          That Council retain the RE1 Public Recreation Zone on Lot 3 DP 593774 and Lot 4 DP593774, Rodeo Drive, Bowraville at this point in time. An amendment to the zone can be considered as part of a future housekeeping amendment.

 

OPTIONS:

 

NIL

 

 

DISCUSSION:

 

Council resolved to proceed with the reclassification of land at Bowraville on the 11 April 2012. A significant history exists in relation to the matter and Council report on the 11 April 2012 best summarises the background to the proposed reclassification. Nevertheless a brief overview is provided in the following:

 

·              Council is the registered proprietor of Lot 3 and 4 in DP 593774 being the land upon which the Nambucca River Jockey Club has its clubhouse and racing facilities (Lot 3) and land forming the starting run to the racecourse proper (Lot 4).  The land is classified as community land.

 

·              Both Lots 3 & 4 in DP 593774 and the adjoining Crown Reserve (actual racecourse) are leased to the Nambucca River Jockey Club until September 2013.  The leases are interdependent.  The rental on each lease is set at the minimum statutory rent of $396.00 per annum.

 

·              Racing NSW is in the process of establishing a minimum venue standard for every racing and training venue in NSW.  The Club has advised that they are committed to achieving minimum standards to ensure the ongoing operation of the racecourse. It is not ideal for the club to place significant investment in land it does not own, therefore Council resolved to sell the land to the club subject to the successful reclassification (11 April 2012).

 

Since this resolution a planning proposal requesting the reclassification of the land was prepared and forwarded to the Department of Planning and Infrastructure for consideration and a gateway determination. Council received a determination from the Director General of the Department dated the 22 August 2012 (copy attached).

 

Among other general requirements the Gateway Panel determined that Council must consider rezoning Lot 3 and 4 in DP 593774 from RE1 Public Recreation to RE2 Private Recreation. In regards to this it is recommended Council retain the RE1 Public Recreation zone on all the land associated with the racecourse until such time the ownership and trustee responsibilities have been determined. At which time the zone amendments could be efficiently incorporated into a house keeping amendment.

 


CONSULTATION:

 

General Manager

 

 

SUSTAINABILITY ASSESSMENT:

 

Environment

 

No changes are proposed to the zoning of the land at this point in time. There are no environmental impacts associated with this report.

 

Social

 

No changes are proposed to the zoning of the land at this point in time. There are no social impacts associated with this report.

 

Economic

 

No changes are proposed to the zoning of the land at this point in time. There are no economic impacts associated with this report.

 

Risk

 

The zoning of the racecourse should be either RE1 or RE2 in full, the land should not be split between the RE1 and RE2 zones. Should Council resolve to amend the zone over the whole racecourse, an amendment to the gateway determination would be required to add Lot 75 DP755549 (Racecourse proper) and should the trustee responsibilities not be transferred to the Jockey Club a further amendment back to RE1 Public Recreation would be required.

 

It is considered best to pursue appropriate zoning on the land when all ownership and management responsibilities are determined.

Assistant General Manager Engineering Services Report

ITEM 11 .3   SF768              300812         Weekes Bridge Reconstruction

 

AUTHOR/ENQUIRIES:     Paul Gallagher, Assistant General Manager - Engineering Services         

 

Summary:

 

Following a delegation from Ms Joan Rossington on the Replacement of Weekes Bridge, South Arm at Council’s Ordinary meeting held 15 August 2012, Council resolved;

 

That the decision on Weekes Bridge be deferred to allow an onsite inspection and consultation with residents.  The inspection to occur at Council’s meeting on 30 August 2012.

 

An onsite inspection with residents is scheduled for Council at 11.30am on Thursday 30 August 2012.

 

 

Recommendation:

 

That Council receive and note the report on the Weekes Bridge reconstruction.

 

 

 

OPTIONS:

 

Under the provisions of Caretaker Mode any decision to vote additional funds towards the bridge would need to be deferred to the incoming Council which may necessitate another site inspection and report to Council on the matter.

 

1        Receive and note the report

2        Reconstruct the bridge as a single lane bridge using ’92 AUSTROADS BRIDGE Design Code

3        Vote an additional $150,000 to build a two lane bridge using Australian Standard AS 5100 (2004) Bridge Design Code

4        Defer the reconstruction of the bridge to the 2012/13 financial year and increase the vote and credit the works order (expenditure incurred to date) and place the bridge components into stock

5        Fund the additional $150,000 via

          a)       $150,000 from 2012/13 general funds (this will have a detrimental effect when it is coupled with the reduction of $191,545 within the FAGS grant (as reported to Council at the ordinary meeting held  26 July 2012)

          b)       $75,000 from 2012/13 general funds (effect similar to “a”) and $75,000 through bringing forward funding from the final year of the roads to recovery grant (R2R) which effectively will delete a rehabilitation project from the final year and will result in a shortened R2R program (moving the issue forward associated with decrease in funding)

6        Reallocate the funding of Weekes bridge to Laverty’s bridge to raise and lengthen the bridge to provide greater flood proofing (Consideration to load limiting the bridge maybe required)

7        Consider trialling the reduction in bridge deck to one lane through traffic barriers, sign posting and road markings and monitor the effect and install traffic counters to update the traffic counts

7        Bring another small bridge to the value of $325,000 forward within the program

8        Undertake extensive maintenance on the bridge and defer the replacement

 

DISCUSSION:

 

Ms Joan Rossington from South Arm Road addressed Council in the public forum on Wednesday 15 August 2012 with respect to the decision to replace Weekes Bridge with a single lane bridge and raised concern around the issue of sight distance onto the bridge as it is located after a blind bend.

 


Community consultation:

 

The first notification to Council in the consideration of reducing the bridge to one lane was provided at the meeting held on 12 May 2011 when Council considered the Draft 2011/12 Management Plan and Budget and the General Manager reported the following:

 

“To present a balanced budget, Council’s management is recommending the deletion or deferral of most new “bids” and some significant reductions and reallocations in existing programs.  It is an austerity budget……..The major changes which are recommended by Council’s management to the initial draft budget are as follows:

 

…..Item 6 The planned replacement of Weekes Bridge on South Arm with a single lane structure instead of a two lane structure (the existing bridge is 2 lane).  This is a reduction in service level and will provide a saving of $150,000”.

 

I advised Council at the meeting held on the 15 August, that I was relatively new to Council at the time of the budget preparation for 2011/12 and that there had been no community consultation leading up to the decision to replace the bridge with a single lane. The decision to reduce the bridge to a single lane emanated when the General Manager sought information from staff as to the cost of a single lane versus that of a two lane bridge to present a balance budget with other worthy competing projects

 

An issue identified with the lack of communication with respect to Weekes Bridge:

 

·            is the timing parameters for the preparation of the 2011/12 budget which did not facilitate any public consultation and the need to present a balanced budget to Council. This is being remedied with the development of the 10 year forward works program and every endeavour is now made to provide adequate consultation across the activities of Council.

·            The reduction in programs are highlighted in the General Managers report on the draft budget to Council which outlines all of the considerations for funding of projects either removed/added or amended from consideration, however the process of advertising the draft  budget may not highlight these changes nor may it reach the all of the public.

 

In the 2012/13 draft budget the General Manager report that the strategy from Council for tackling the financial issues are detailed on pages 12 and 13 of our Operational Plan and Delivery Program as follows:

 

"A balanced budget for 2012/2013 has only been achieved through the non-replacement of staff, additional borrowings and the deferral of required capital expenditure.  This is an unsustainable strategy.

 

The problem exists because Council's General Fund is being "squeezed" on the revenue side by rate pegging and on the cost side by depreciating infrastructure which has to be renewed and replaced in a timely way.  This infrastructure includes 170 bridges, 247km of sealed rural roads, 105km of urban streets and 345km of unsealed rural roads.  Inadequate funding of the depreciation of this infrastructure is the challenge for Council.  If the problem is left unattended, Council will fail in its core function of providing physical access to properties.

 

Cost shifting from the State Government such as through reduced regional road funding and increased contributions to the Rural Fire Service adds to the problem.  Council has to determine how it will reduce its services to a level which is financially sustainable.  In the latter part of 2012, Council will explore a number of measures that may help reduce its expenditure on infrastructure, including:

*  reduce the service level of bridges, with bridges going from two lane to single lane where possible

 

Bridge replacement program:

 

The reconstruction of Weekes Bridge on South Arm Road was identified in Council’s bridge replacement program for the 2011/12 financial year.  Provision of $325,000 was allocated in the 2011/12 budget to build a single lane bridge following Council’s adoption of the budget 

 

The bridge was scheduled for replacement before the end of the 2011/12 financial year through the months of May/June 2012 following the completion of Johns’s Bridge.  Due to the adverse weather experienced across the Shire, the entire bridge construction program was adversely affected and delayed the reconstruction of Weekes Bridge. All of the bridge components were ordered in the 2011/12 budget and stored at the Works Depot with the revote for 2012/13 encompassing labour and machinery only.

 

The weather forecast was favourable for work to commence on 27 August 2012 as a side track is required to be constructed to maintain access, however work has now been deferred pending the decision of Council following the site inspection. In the interim the bridge gang has been redeployed onto bridge maintenance.

 

Supply of bridge components:

 

Due to the production lead time required for the supply of bridge components, orders are now placed with suppliers some six months in advance of the budget and the items placed into store and booked out when works are scheduled to commence.

 

The bridge components for Weekes Bridge were ordered in the 2011/12 budget and stored at the Works Depot with the revote for 2012/13 encompassing labour and machinery only. In the event that the replacement of the bridge is deferred, the components would be credited back to the stores and most probably redirected to other works.

 

Condition of the bridge:

 

Council has about 35 bridges listed in Councils Asset Management Plan that are classified in condition 4 (poor condition requiring close monitoring) and about 10 bridges classified in condition 5 (very poor - failure imminent). Weekes Bridge is one of 45 bridges listed in these condition ratings

 

Council undertook minor maintenance on the bridge approximately 2 years ago with the knowledge that it was on the bridge replacement schedule for 2011/12. Economically it is not a recommended viable or sustainable solution to expend any further funds on the bridge when it is to be replaced.  Whilst the bridge is not in immediate danger of collapsing substantial work and/or a potential load limit on the bridge would need to be considered to ensure that the replacement of the bridge can be deferred.  .

 

Funding:

 

Councils Timber Bridge Replacement Infrastructure Planning Program identified the replacement cost of a two lane bridge for Weekes Bridge at $475,000 funded by external loans. The $150,000 has not been reallocated elsewhere across Council activities and there are also savings attributed on the interest that would have been payable on the loan.  The reduction in service level to that of a single lane bridge is a net reduction in Councils budget by $150,000  

 

There are no Federal or State Government grant programs for bridges on local roads.  The Local Infrastructure Renewal Scheme (LIRS) provides a 4% interest rate discount on approved capital works and Council is utilizing the LIRS funding to replace the Eungai and Laverty's Bridges.

 

If the replacement of the bridge is deferred and replaced with a two lane structure, the additional expenditure will result in something else being pushed back in the bridge replacement program and presumably increasing the risk of an unscheduled bridge failure. 

 

The decision to reduce the bridge to one lane is based on economical savings and presenting a balance budget with other competing programs, rate pegging and state government cost shifting. The replacement cost of a two lane bridge is $475,000 compared to that of a single lane bridge at $325,000. In considering the reduction in allocation, the issue of safety is addressed through the design parameters and appropriate road signage and markings in accordance with the Australian Standards. (Consideration is also being given in the design to battering the embankments on the eastern approach to assist with site distance)

 


Bridge design:

 

Based on the number of aging bridges requiring replacement across the Shire, the economic funding issues associated with rate pegging, working to a balanced budget and external state government funding factors such as the continued increase RFS charges, Council began a review of the levels of service within the bridge program and where feasible considered the construction of single lane bridges.

 

’92 AUSTROADS BRIDGE Design Code and the updated Australian Standard AS 5100 (2004) Bridge Design Code both state that the road bridge carriage way widths are determined by the Authority (Council) based on consistent levels of service along the section of roadway taking into account

a)       Road geometry

b)       Traffic volumes

c)       Bridge locality

The updated Australian Standard AS 5100 (2004) Bridge Design Code has been developed to facilitate design and build contracts and therefore does not comment on the economic considerations of the local Authority, whereas the ’92 AUSTROADS BRIDGE Design Code principles are based on projects administered by the infrastructure owners (Council)

 

With all Council’s activities there is an emphasis placed onto risk management and whether the risk can be mitigated or managed satisfactory. Compliance with the Australian Standards is seen as “best practice” in the industry for products and services in the Australian market, and is normally voluntary unless the products or services are regulated by the Government.

 

The risk when using the ’92 AUSTROADS BRIDGE Design Code  is addressed through the consideration of traffic counts, location of the site and the usage of signage and road markings for one lane bridges in accordance with Australian Standard 1742.2 (2009) Uniform Traffic Control devices.

 

Council use traffic counters to obtain the traffic volume flows across the local road network, these traffic counts are then used as a guide to determine the hierarchy of the road network, frequency of use and consideration of maintenance and construction treatments and designs of the pavement.

 

In determining the reduction to a single lane bridge the utilisation on the road is one of the factors considered, A projected flow of 180 vehicles per day has been assumed for design purposes due to the last traffic count being four years old  Traffic counts for South Arm Road were taken from Menzies Road towards the bridge (166 vehicles per day in 1997) and a count taken later between Williams Hill and Menzies Road (167 vehicles per day in 2008) which indicates little change in traffic movements..

 

At the Council meeting held on 15 August 2012, a traffic comparison was made between Weekes bridge and the newly constructed bridge at Deep Creek. I was advised by the General Manager that the traffic counts referenced for Deep Creek Bridge in discussion prior to the Council meeting were up to 1000 vehicles per day and this was relayed verbally at the meeting. The actual count has been verified and is 431 vehicles per day (over double that of Weekes Bridge) and are 8 years old (taken prior to the bridge being closed and possibly heavy influenced by traffic movements to the local quarry) Council has not taken any recent traffic counts on this road since the bridge was reopened to traffic

 

Council adhere to best practice guidelines when using either the ’92 AUSTROADS BRIDGE Design Code or Australian Standard AS 5100 (2004) Bridge Design Code Both codes in conjunction with Australian Standard 1742.2 (2009) Uniform Traffic Control devices allows the consideration in the reduction of service levels on a case by case basis following consideration of the road geometry, traffic volumes and the bridge locality (using this philosophy consideration of single or double lane bridge replacement within the Shire will be on a case by case basis)

SUSTAINABILITY ASSESSMENT:

 

Environment

 

There are no environmental implications associated with this report.

 

Social

 

There are social implications in the event the bridge is closed as it is to only access to this area.

 

Economic

 

The are economic implications associated with this report attributed to the perceived risk of accidents attributed to the narrowing of the bridge to one lane, The bridge construction and signage will be accordance with Australian Standards (and will consider the battering of the eastern approach batters).

 

Risk

 

The are risk implications associated with the narrowing of the bridge with respect to the sight distance onto the bridge, The vehicle counts for this area are projected at 180 vehicles a day with the majority of traffic movements being in the morning and evening (to and from work and school etc). The approach signage and road markings to denote a narrow bridge will be accordance with the Australian Standards.

 

 

FINANCIAL IMPLICATIONS:

 

Direct and indirect impact on current and future budgets

 

There will be a direct impact on the 2012/13 budget to construct a two lane bridge associated with the additional $150,000 required, and alternatively if the bridge program is amended to defer the reconstruction of Weekes Bridge.

Assistant General Manager Engineering Services Report

ITEM 11 .4   SF741              300812         Paveline Patching Machine - Operation

 

AUTHOR/ENQUIRIES:     Noel Chapman, Manager Civil Works         

 

Summary:

 

Council at its meeting on 16 July 2009 resolved that:

 

"Council receive a report on Paveliner performance in terms of cost per cubic metre and other relevant parameters and including the Director Engineering Services' opinion on efficiency or otherwise of the machine and what is required to improve performance.  Also options for addressing loose stone and the option of a sweeper attachment.  Comparative data is to be provided for a defined period of usage."

 

The report uses data collection from Council Maintenance Management System, Reflect, for the twelve month period July 2011 to June 2012.

 

The table shows a general correlation between the target and actual rates for most criteria.

 

 

Recommendation:

 

1        That the report on the operations of the Paveline for July 2011 to June 2012 be received and noted.

 

 

 

OPTIONS:

 

1        Note the report

2        Request further information.

 

 

DISCUSSION:

 

The statistics show the following average figures:

 

 

JULY 10 – JUNE 11

JULY 11 – JUNE 2012

Square metres patched over 12 months

34124

22481

Square metres per day

196.12

116.48

Cubic metres of aggregate per day

9.81

5.82

Tonne of aggregate per day

6.63

5.25

Cost per square metre of patching

NA

NA

Cost per tonne

NA

NA

 

Note:  These figures include some use of premix and broad area spraying not separately identified.  The broad area spraying results is an under estimation of area treated and an apparent higher cost per square metre.

 

The target or benchmark for comparison is twofold.  The initial report to Council forecasts figures of:

          i)        25,200 square metres per annum

          ii)       120 square metres per day

          iii)      6.0 cubic metres of aggregate per day

          iv)       9.0 tonne of aggregate per day

          v)       $14.50 cost per square metre of patching

          vi)       $193.33 cost per tonne.

 

The other comparison to be made is against the older style of patching using a Flowcon and Pre-mix material.  Those forecast figures are:

 

          a)       10,500 square metres per annum

          b)       50 square metres per day

          c)       2.5 cubic metres per premix per day

          d)       $44.23 cost per square metre of patching

          e)       $368.58 cost per tonne of premix.

 

As a result of the change to the Authority Finance System the costing link to the Maintenance Management System has been lost.  Discussions are being held to establish a link.  In the meantime cost comparisons are not available.

SUSTAINABILITY ASSESSMENT:

 

Environment

 

Raw materials are sourced from quarry/mining operations.  There are no other methods available to reduce environmental impacts.

 

Social

 

There are no issues as a result of this report.

 

Economic

 

Better road surface reduces transport costs.

 

Risk

 

Loose stone can create a traffic hazard.  More experience gained by operators will minimise the impact.  Better quality emulsion is also having a positive impact.  The truck is currently fitted with a broom to enable sweeping as required.

 

 

FINANCIAL IMPLICATIONS:

 

Direct and indirect impact on current and future budgets

 

As the operation improves the road system will benefit which could reduce the budget requirement in future years.

 

Source of fund and any variance to working funds

 

No additional funds are required as the result of this report.
