BP 2

iv. Measurement

Payment for all work completed will be based on the quantities stated on the agreed Programme. No payment will be made for any work completed by the Contractor that was:

a) not agreed with the Engineer

b) not on an agreed Programme

c) deleted by the Engineer from any Programme d) not fully complete at the time of measurement. No additional payment will be made for any increase in the extent of work required to complete Task(s) if this happened only because the Task(s) were not completed by the date shown on the agreed Programme.

v. Engineer's Assessment and Measurement

If the Engineer's reviews and inspections of the Contract Works show:

a) the quality assurance records are incomplete and/or

b) some aspects of the Contract Works are non-complying, the Engineer may:

value the works according to General Conditions, Clause 12.1.3

instruct the Contractor to identify and rectify all non-complying work

arrange for the work to be completed by any such means the Engineer considers appropriate. If time permits, the Contractor will be advised of the Engineer's intentions and given the opportunity to complete the work within the time frame agreed with the Engineer.

All costs of initiating, managing and completing any such work may be deducted from the Contractor's payments. These costs will be based on the rates stated under Conditions of Contract, First Schedule, Clause 6.4.6. If the remedial work is completed, the Engineer may: i) reassess and value the work ii) instruct the Contractor to complete further remedial work. No additional payment will be made for any increase in the extent of work required to complete Task(s) if this happened only because the Task(s) were not completed by the date shown on the agreed Programme.

Basis of Payment

1 Preamble


BP 3

v.1 Payment Valuation

Further to General Conditions, Clause 12.1, the Engineer's valuation of the Contractor's claims will be based on the inspection and assessment of: a) a sample or samples of the claimed unit rate tasks to determine unit rate task's compliance b) a sample or samples of at least 10% of the network's length, selected on a random basis, to

determine cyclic maintenance task's compliance. The Engineer will: i) invite the Contractor to participate in the sampling, inspection and assessment of the first

payment claim ii) make available all records and documentation that support each claim's valuation. Any reduction in payment in accordance with these provisions shall be without prejudice to the provisions of Section 14 of the General Conditions.

v.1.1 Sampling

Unit Rate Tasks The unit rate task sample will include: a) all unit rate tasks greater than 20m² in total area or 10m in total length as appropriate b) all unit rate tasks greater than $5,000.00 in value c) a random sample of the remaining unit rate tasks so:

the total sample size is at least 10% of the total number of unit rate tasks claimed and

the total sample value is at least 10% of the total value of unit rate tasks claimed. These inspections will be completed between the date the claim is received and the date the claim is certified for payment. Cyclic Maintenance The assessment of cyclic maintenance task compliance will be based on an inspection and assessment of at least 10% of the total length of highway and/or total number of areas, as appropriate, within the network each month.

Basis of Payment

1 Preamble


BP 4

The Engineer will: a) split the network into discrete kilometre sections and/or areas

b) provide a copy of this list to the Contractor at the start of the contract

c) select on a random basis a sample or samples comprising at least 10% of the total number of sections and/or areas each month.

These inspections will be completed at any time during the period the claim applies to.

v.1.2 Sample Assessment

Unit Rate Tasks For each selected task, the Engineer will determine whether it complies with the Contract Documents. The percentage compliance will be: a) calculated using the following formula. If the Engineer includes any other unit rate tasks, not

selected in the original sample, in the assessment, then the sample size used in the calculation will be the total number of unit rate tasks claimed.

b) expressed as a percentage and rounded to the nearest whole number.

The results will be used to help value the Contractor's claim according to General Conditions, Clause 12.1 Contractor's payment claims. Unit Rate Compliance (%) = (Total Number of Tasks Inspected - Number of Non-complying Tasks Identified) Total Number of Tasks Inspected Cyclic Maintenance Tasks For each cyclic maintenance task, the Engineer will: a) inspect each selected section and determine whether it complies with the Contract Documents.

If a defect is identified and a response time is:

stated, the Engineer will re-inspect the section after the specified response time has lapsed. If the defect remains, the section will be non-complying for the month

not stated, the section will be non-complying for the month

b) advise the Contractor of the location of all defects by schedule item, state highway and

reference station within 24 hours of the time each defect is identified. The specific route position of the defect will not be stated

Basis of Payment

1 Preamble


BP 5

c) attach a list detailing the specific location of all non-complying defects to the payment certificate.

The percentage compliance will be: i) calculated using the following formula. If the Engineer includes any other sections, not

selected in the original sample, in the assessment, then the sample size used in the calculation will be the total number of sections within the network.

ii) expressed as a percentage, rounded to the nearest whole number. Cyclic Assessment (%) = (Total Number of Sections Inspected - Number of Non-complying Sections Identified) Total Number of Sections Inspected The percentage compliance will be used to value the Contractor's cyclic maintenance claim according to the following table. If the percentage compliance is less than or equal to 29% the work completed by the Contractor during the month is of no value to the Principal and no payment will be made.

v.1.3 Sample Size

The total sample size will be determined by the discretion of the Engineer, subject to the minimum sample size which must be inspected in respect of each claim. If the claim valuation process results in: a) percentage compliance of greater than 95% for 3 or more consecutive months then the

Engineer may, in consultation with the Principal, reduce the minimum total sample size used in the assessment to 5%. If the percentage compliance then drops below 95% then the minimum total sample size will revert to 10%

b) percentage compliance of less than 90% the Engineer may, in consultation with the Principal,

increase the minimum total sample size used in the assessment to a minimum of 20%. If the percentage compliance increases to greater than or equal to 90% for two consecutive months then the minimum total sample size will revert to 10%.

1. Contract Works

1.1 Scope

This Section describes the extent and location of the Contract Works, the Contractor's and Engineer's obligations and describes performance reviews.

1.2 Contract Works' Description

This Contract is for:

a) providing the cost effective road and associated facilities maintenance within a network and the operation of the network. Cost effective maintenance may cause some performance measures, that monitor the network's condition, to deteriorate.

b) providing appropriate resources to respond to incidents (crashes, spills etc.) that may occur within the network

c) providing appropriate resources to respond to incidents (storm damage, emergency events

etc.) that may occur within the network including:

assisting the Engineer to develop appropriate measures and plans to mitigate and manage emergencies, prior to an emergency event occurring.

providing resources and managing the response to incidents and emergency events affecting the safety or integrity of the network.

the reestablishment and/or reinstatement of network access affected by incidents and emergency events at the discretion of the Engineer. The permanent reinstatement of emergency events may be separately contracted.

This Contract is not for upgrading the network to an as new condition. This means it is appropriate for a section of highway:

i) to deteriorate in anticipation of programmed maintenance and/or rehabilitation and/or reconstruction in future years

ii) to have many small repairs rather than single larger repairs that include treatment of sound pavement

The Operational Requirements detail the specific requirements that apply to this Contract.

This contract requires a high degree of co-operation between the Contractor and the Engineer. The detailed investigations carried out by the Contractor to facilitate the design of the works may necessitate review of the outputs of the treatment selection process. In some cases technical reviews may be necessary to resolve the most effective treatment and such reviews may involve the utilisation of external resources. The treatment selection and design processes, and roles and responsibilities relating to these, are described in Transit's State Highway Asset Management Manual.

MS 2

1.2.1 Extent

The Contract Works (see General Conditions, Clause 1.2) are described in this Maintenance Specification, summarised in the Schedule of Prices and include:

a) implementing a CQP to enable the completion of the Contract Works (see Section 2)

b) providing all labour, plant and materials required to complete the Contract Works.

The Contract Works may exclude:

i) maintaining private accessways and pedestrian facilities located outside the kerb line and/or edge of seal unless specifically provided for in these Contract Documents

ii) maintaining culverts, sumps and associated stormwater structures within urban areas unless specifically provided for in these Contract Documents

iii) drainage maintenance works and major drainage control. These are described in NZTA’s Planning, programming and funding Manual, Section 2.3 under Work Categories 113 and 213

iv) traffic services maintenance

v) pre-surfacing repairs and pre-surfacing treatments

vi) pavement repairs located within sections of pavement that meet the funding criteria for area wide treatment or smoothing projects (see NZTA’s Planning, programming and funding Manual, Sections 2.3, Work Category 111 and Section 2.4, Work Category 214). In general these sections are:

shown in the Ten Year Programme (see Section 4)

are greater than 100m long.

If the maintenance works proceed, they must be completed as an area treatment and revised rates for the work agreed (see Basis of Payment, Clause ix)

vii) Schedule rates do not apply to repairs greater than 100m² in area

viii)Rehabilitation and Construction Works.

The Contractor shall proactively programme Maintenance Area Wide Pavement Treatments (between 100m2 and 800m2), where numerous patch repairs become uneconomic. The Maintenance Intervention Strategy (MIS) details when these Maintenance Area Wide Pavement Treatments are to be programmed. The Contractor and Engineer are to agree that the implementation of repairs will provide for the lowest maintenance cost option before approval. The Contractor shall be responsible for the pavement investigation and design, and shall demonstrate that the required design life is achievable.


1 Contract Works


MS 3

If the Engineer requests the Contractor to complete maintenance works described in items vi) and/or viii) above, these works shall be undertaken as a variation in accordance with Section 9 of NZS3910: 2003.

1.2.2 Location

The Contract Works are located within the network described in Operational Requirements, Clause 2. The network includes:

a) all carriageway, bridges and other structures, stormwater structures, roadside furniture and road safety barrier systems, and encompasses the road reserve bound by existing fences or road reserve boundaries

b) all established rest areas and roads, bridges and stormwater structures within these areas.

c) If a local road intersects the state highway at grade, the Contractor must maintain the state highway for a distance of 10 metres from the limit line position or to the end of seal, whichever is the lesser. This maintenance includes:

Pavement maintenance Maintenance of regulatory signs associated with the intersection Maintenance of pavement marking related to traffic control of the intersection where

these are appropriate Maintenance of raised traffic islands related to the traffic control of the intersection

The Contractor will continue to maintain the network through lengths affected by other construction projects, unless directed by the Engineer to stop specific activities.

1.3 Obligations 1.3.1 Contractor's Obligations

The Contractor must:

a) ensure that the proposed treatment is appropriate

b) programme and complete all work in accordance with Section 4. Each Programme must be compiled according to the programming constraints and meet the network's needs

c) establish and maintain appropriate systems to monitor and report against specified performance indicators (see Clause 1.5.3).

d) ensure that sufficient resources are maintained to source the needs of the contract, both for programmed and scheduled works and for unscheduled works and emergency works.

This means the Contractor must:

i) proactively manage this Contract

ii) provide appropriate resources to respond to incidents


1 Contract Works


MS 4

iii) intervene so the area and/or type of deterioration does not increase. It is recognised however that the implementation strategies may be necessary, which may result in constraints being placed on maintenance activity and, ultimately, deterioration in the condition of some areas within the network.

iv) programme cost effective repairs. This requires a proactive approach so the first signs of deterioration are addressed. An example of this is completing crack sealing rather than allowing the pavement to fail and completing a digout repair

v) liaise with the other contractors working within the network and in particular the resurfacing and pavement marking contractors.

3.11 Plant and Equipment

All plant and equipment must be selected to minimise damage to the pavement, traffic control devices, roadside facilities and surrounding area. The Contractor may be instructed to remove any excessively weighted or sized plant which may adversely affect the condition of the network.

All plant and equipment must be :

a) registered for normal use on the road b) operated on surfaced roads so the turning and/or traction of tyres and/or steel blades and

buckets does not cause displacement of the surfacing materials.

Tracked machinery must not be operated on any surfaced pavement without the Engineer's prior approval.

In addition, the Contractor must ensure

i) the movement of any steel drummed compaction equipment outside the area of the task is minimised

ii) equipment depositing bitumen and emulsion outside the area of the work is removed from site.

If any damage to the network is caused by the Contractor's operation it must be repaired, at the Contractor's cost, to a standard no worse than that existing before the work began.

3.12 Other Contractors

Contractors may be working within the network at various times (see General Conditions, Clause 5.5). This work may include but is not limited to other routine maintenance works, pre-reseal repairs and associated surfacing works, installation of services.

The presence of other contractors does not relieve the Contractor of their obligations to maintain the network according to the Contract Documents, unless the presence of other contractors directly affects the Contract Works.

In this case the Contractor must advise the Engineer within 24 hours.

3.13 Publications and Standards

In addition to this Specification, the following Transit/NZTA publications and standard specifications also form part of but are not reproduced in the Contract Documents.

3.16 Forward Work Programme Field Inspections 3.16.1 Objectives / Requirements

The objectives of involving the Contractor in the Forward Work Programme Field Inspections are as follows:

to increase the awareness of the Contractor concerning the inputs and strategies involved with

the development of the Forward Work Programme (FWP).

to increase the awareness of the Contractor concerning the way the available network information data is used to schedule future treatments.

to increase the understanding of how the actions or inactions of the Contractor can affect the condition of the network, and on the programming of future treatments.

to utilise the Contractor’s network knowledge in any reviews of the FWP.

to ensure that the Contractors knowledge of network performance based on their inputs are taken into account

The Contractor is to make available at least one management staff member to accompany the Engineer during the FWP field inspections required bi-annually each year of the Contract.

It is the NZTA’s expectation that the Contractor’s staff member will be someone who is closely associated with the development of the Contractor’s monthly pavement maintenance programmes, has an in depth understanding of the Maintenance Intervention Strategies that need to be applied, and has a detailed understanding of the network and its characteristics.

The Forward Work Programme (FWP) is a commitment by the NZTA, and therefore can always be used for programming, however it is always subject to change. The risk of change is reduced following the October review one year in advance of when the reseal is due to commence. Pre-reseal repairs should be identified and programmed in the subsequent year reseal lengths as soon as possible following receipt of the October review of the Forward Work Programme.




MS 24

3.17 Removal and/or Recycling of Damaged Components

The Contractor is responsible for dismantling and removal from site of all damaged or broken components. However, where possible the Contractor is encouraged to recycle components which may be damaged but provide additional life without compromising the level of service required or standards.

The Programme must be submitted in both hard copy and electronic format. Appendix 4.1 sets out the electronic format. The Contractor may provide partial programme submissions to the Engineer only if prior approval by the Engineer has been sought.




MS 38

This would permit the Contractor to submit more than one programme per month covering an agreed portion of the state highway network at a time, rather than a single monthly programme covering the entire network within any monthly cycle. The Engineer's approval for the adoption of partial programme submissions would be subject to the Contractor demonstrating an ability to consistently programme the maintenance work effectively and with an error rate well below the 5% threshold. The Engineer may withdraw approval for the continuance of the partial programme submissions at anytime the Contractor fails to maintain the required programming standard.

4.5.1 Programming Constraints

All Programmes must be prepared so they comply with the following constraints: 4.5.1.1. Ten Year Programme

The Engineer maintains the Ten Year Programme (TYP) for the network. The TYP:

a) details all proposed work, by location and type, to be completed within the network

b) states the maintenance strategy that applies to each section of the network

c) is based on the outputs from the NZ Transport Agency's Annual Roading Programme, the Engineer's and Contractor's inspections and financial constraints

d) is formally updated and issued to the Contractor on a six monthly basis. 4.5.1.2. Maintenance Intervention Strategy

The Maintenance Intervention Strategy (MIS):

a) states the type and extent of work permitted under each maintenance strategy

b) is dependent on the highway environment.

This means in some cases, e.g. sections programmed for rehabilitation or reconstruction holding type repair(s) will be preferred to full cost repairs.

The risks associated with the repairs' performance will be carried by the Principal provided the Contractor can demonstrate the repair was completed according to the Contract Documents.

If the Contractor considers the risk of completing holding repairs is too great, the Contractor must advise the Engineer and propose alternative treatment(s)

The MIS is an evolving document and demands both the Contractor's and Engineer's input for its ongoing development and effective implementation.

4.5.1.3. Extent of Finance

All Programmes must be prepared so the value of the Programme approximately equals the value shown on the Contractor's budget forecast for the relevant period (see Clause 4.5.2).




MS 39

4.5.1.4. Other Constraints

The Operational Requirements section details other programming constraints that apply. 4.5.2 Projected Monthly Expenditure 4.5.2.1. Budget Forecast

The Contractor must provide a budget forecast for each payment item number (see Appendix 4.2) and the Contract Works with their initial Programme. The budget forecast must:

a) show the proposed monthly expenditure for each payment item number

b) form the basis of the financial performance indicators, evaluation (see Clause 1.5). 4.5.2.2. Projected Monthly Expenditure

The Contractor must provide the Programmed Monthly Expenditure with each subsequent Programme and Monthly Report. The Programmed Monthly Expenditure:

a) is a financial statement, in accrual terms, of the past, current and projected financial status of the contract for each month of the contract period

b) must state, for each payment item number and the Contract Works, for each month of the financial year:

the value of work certified for payment by the Engineer including all retentions

the value of withheld money that may be returned to the Contractor

any claims the Contractor may submit, including work that has been completed but to date not claimed

the estimated value of work to be completed for each month to the end of the financial year

c) must identify any budget surpluses and/or shortfalls. In these cases the Contractor must recommend appropriate transfers or release of surplus monies.

4.5.3 Detailed Programme

The Detailed Programme must state for each fault, programmed under Unit Rate Items the:

a) fault and activity codes as defined in State Highway Database Operation Manual, SM050, Appendix 4

b) proposed method of treatment and/or repair and description of the work, referenced to the appropriate Item(s) in the Schedule of Prices

c) unique task number. If a proposed task is deleted from the Programme, the task number must not be re assigned to another task

d) task priority (see Clause 4.5.3.1)

e) location of the work by state highway and route position




MS 40

f) side of the carriageway, and, in multi-laned areas, the lane (e.g. left, centre, right)

g) extent of the work including length, width and depth (as appropriate)

h) units of measurement

i) total quantity, tendered rate and total value. 4.5.3.1. Task Priority

Each task must be assigned a priority of 1 to 4:

a) Priority 1 Tasks are for fault repairs that are:

not unsafe but may become so if they are not repaired by the 15th calendar day of the month

expected to increase in size and cost if left for longer than two weeks (from the 1st day of the month the Programme applies to).

b) Priority 2 Tasks are for fault repairs that are:

not unsafe but may become so if they are not repaired by the last day of the month

expected to increase in size and cost if left for longer than 4 weeks.

c) Priority 3 Tasks are for fault repairs that are:

not unsafe but may become so if they are not repaired by the last day of the second month

expected to increase in size and cost if left for longer than 8 weeks.

d) Priority 4 Tasks are for fault repairs that:

may increase in size and cost if left for longer than 12 weeks

can be considered desirable, but if not completed will not result in network's deterioration (i.e. they are not necessary to complete within 12 weeks).

4.6 Programme Implementation and Management 4.6.1 Responsibilities 4.6.1.1. Contractor's Responsibilities

When agreed, the Contractor must:

a) provide sufficient resources to complete all works by the dates specified in the Programme

b) with the agreement of the Engineer, adjust the priorities of the work to meet the network's needs. This may mean some tasks included in Months 2 and 3 have to be re-prioritised and accelerated or deferred.




MS 41

The Contractor shall advise the Engineer immediately of any variation required to the dimensions or proposed method of undertaking the programmed treatment or repair, if such variations become apparent after excavation has commenced.

4.6.1.2. Engineer's Responsibilities

If the Engineer's reviews and network inspections (see Sections 2 and 3) show the Contractor is not managing the Programme effectively, the Engineer may re-prioritise the Programme and instruct the Contractor accordingly.

4.6.2 Urgent Work

The Engineer may notify the Contractor that a task is to be completed as urgent work if:

a) the safety of the public or private property may be compromised, or

b) it is likely the area of distress may increase or the method of repair change so the cost of the repair increases, or

c) subsequent work may depend on the task's completion, or

d) it originates from a public complaint. 4.6.3 Variation to Method and/or Dimensions of Repair

If variations to the dimensions or proposed method of repair become apparent once the repair is started, the Contractor must:

a) advise the Engineer immediately of the task number and reasons for the variation

b) write, confirming the extent, value and reasons for the additional work. 4.6.4 Outstanding Work, Work in Progress and Non-complying Work

All Outstanding Work, Work in Progress and Non-complying Work, must be re-programmed for completion during the current month (see Clause 4.5).

If the cumulative number of Tasks that have not been started (Outstanding Work) is greater than 10% of the total number of tasks in the current programme, the Engineer reserves the right to have the work completed by another contractor on behalf of and at the cost of the Contractor (see Basis of Payment, Preamble, Clause v).

23. Drainage Improvements

23.1 Scope

This section sets out the requirement for improving the existing drainage facilities. 23.2 Definitions


23.3 Response Times The Contractor must complete all work required by this Section by the dates shown on the agreed programme.


23.4.1 Extent of Work

The extent of work is as follows: i) shaping of side slopes

ii) cleaning and/or regarding of surface water channels and side drains

iii) disposal of surplus material

iv) provision of traffic control, and quality control testing required to facilitate the work

v) temporary removal and permanent replacement of existing edge marker posts, culvert marker posts, and permanent signs, that are affected by the work

vi) grassing of side slopes.

The intention of the works contained within this contract is to ensure that runoff water from the highway can be readily conveyed through the drainage network, to avoid excessive penetration into the road shoulder. As such the Contractor shall ensure that the required crossfalls and drainage paths are suitably constructed.

The work is not to extend beyond a point 0.5m from existing fence lines, except for ‘drainage cut out’ work. Excavation into banks or batter slopes above 1.5m in height is not required.

23.4.2 Monthly Programming

Further to Section 4 of the maintenance specification, the Contractor shall identify and programme the following: i) side slope shaping sites (cut 1:6)

ii) surface water channels that require cleaning and/or regrading

iii) side drains that require cleaning and/or regrading

iv) subsoil drains that require flushing




MS 118

Unless the drainage deficiency is a safety issue or hazardous to motorists, all drainage work covered by this section of the contract may be programmed with a priority 3 or 4 to allow the Contractor better efficiencies in completing the work. The programme shall be agreed with the Engineer prior to any work commencing on site.

The Contractor shall also identify drainage system deficiencies that arise beyond the boundary of the road reserve. These sites shall be identified as part of the monthly programme and shall include the following:

i) location (i.e. RS, RP, and side of road)

ii) nature of the defect (e.g. blockage)

iii) remedy required (e.g. clean and regrade drain for 20m) 23.4.3 Disposal of Material

No spreading of material within the State Highway road reserve is permitted. All trimmed or excavated material shall be removed from site.

23.4.4 Plant

No tracked construction plant shall be used in the contract works. Construction plant and methodology shall be chosen to enable the following requirements to be met.

i) disruption to traffic flow shall be the minimum possible

ii) surplus material is to be removed within the area of excavation and shall not be dragged or placed onto the seal.

In wet or unstable ground (e.g.. in situ gravel), once the required edge shape has been achieved, construction plant shall not disturb the finished surface.

23.4.5 Cleaning of Sealed Surfaces

Any detritus spilled onto the road as a result of the Contractor’s operations shall be totally removed from the sealed surface as part of the Contractor’s daily operation and before work ceases on site for the day. In wet weather and in circumstances beyond the control of the Contractor which prevent complete removal of all detritus before work ceases on site for the day, the Contractor shall, with the agreement of the Engineer, employ a temporary holding strategy. The temporary holding strategy shall ensure traffic is not exposed to detritus or a greasy sealed carriageway surface during periods of inclement weather, and ensure that the surface remains in a safe and trafficable condition throughout the period of the cleaning operation. If the sealed carriageway surface becomes unsafe, which in this context includes consideration of skid resistance, texture, roughness and detritus, the Contractor shall immediately remove all detritus from the road surface. The




MS 119

Contractor shall ensure that the temporary holding strategy used is not detrimental to the sealed carriageway surface.

23.4.6 Side Slope Shaping (Cut1:6’s)

23.4.6.1. Quality Control Testing The Contractor will be expected to carry out (and may be required to provide to the Engineer records of these) measurements at 20m intervals which confirm that the dimensions and side slope gradient comply with the contract requirements, including:

i) width between edgeline and cut away point

ii) width between cut away point and the outer extremity of the side slope

iii) gradient of the shaped side slope

iv) confirmation that the check with a two metre long straight edge reveals no gaps greater than 25mm on each shaped batter.

23.4.6.2. Location of Sites and Setting Out

The lateral dimension of the cut away point shall commence at a nominal distance of 100mm from the edge of seal. This will be true for all 1:6 sites completed under this contract unless specifically stated otherwise.

23.4.6.3. General Cross Section

The objective is to shape the verges to provide a nominal 1:6 side slope over a minimum of 2.5 metres from the outside edge of the 100mm unsealed shoulder to the invert of the surface water channel. At locations where the shaping of the side slopes creates a high verge beyond the surface water channel, the cut batter sloping away from the channel shall be constructed with a backslope of 1 to 2. However, where there is a side drain or ground shape that is lower than the new surface water channel and within 2 metres of it, then the verge shall be further excavated, shaped and trimmed to provide a crossfall beyond the surface water channel of 1 :12 to shed the runoff into the lower side drain or onto the lower ground. The tolerance for the side slope shall be no steeper than 1:5.75 and no flatter than 1:6.25. However, the Contractor shall undertake additional excavation as necessary to ensure that a positive crossfall of at least 1:12 exists between the edge of seal and the cutaway point at any particular cross section.

23.4.6.4. Special Cross Section At locations where vehicles frequently pull onto or off the carriageway, such as at side roads, entranceways, scenic spots and rest areas which do not have specifically formed or defined access




MS 120

points, the side slopes shall be no steeper than 1:7 and no flatter than 1:9 extending over a minimum width of 3.0 metres at this slope. If there is any uncertainty about the shaping of side slopes at entranceways, the Engineer is to be consulted before construction takes place. Opposite private entranceways where sealed carriageway width is less than 6.2 metres and existing shoulder is within the slope parameters referred to in the paragraph above, then a 10m length of shoulder on the approach side of the entranceway shall be retained. At locations where the side slopes are intercepted by side roads the slope shall be transitioned to the side road over a distance of 30m and at property entranceways over a distance of 5 metres as shown in Appendix 1.4.

23.4.6.5. General Requirements All work shall be carried out to provide adequate disposal of water from the newly formed drainage channels. Ponding of water will not be acceptable. Wherever practicable watertables shall have cut outs at not more than 50 metre intervals and at low points so that water drains away from the pavement. The cut outs shall be sites to avoid risk of damage to roadside structures from washout. Care shall be exercised to avoid damage to the seal edge. The Contractor shall have available on site at all times suitable equipment for ensuring the correct side slopes are achieved and side drains are graded adequately. The shaped and trimmed surfaces shall be even and consistent. For inspection purposes, the surface shall be unacceptable if gaps in excess of 25mm and evident beneath a 2 metre long straight edge placed anywhere on the batter. The finished surface shall be dense and consolidated, and free of large clods of earth or vegetation and large stones which could damage the mowers. Final trimming may not be required provided the surface is not undercut and is left tight and compacted. If the surface is undercut in error beyond the design limits, then the shortfall is to be remade with TNZ M/4 basecourse and shaped and compacted by rolling at the Contractor’s expense.

23.4.6.6. Grass Seeding All areas of the shaped side slopes and verges shall be grassed by spreading seed on the finished surfaces. The seed mix shall be spread at a rate of 12.0g/m2. The seed mix ratio shall be: one third Brown Top (Agrostis Capillaris)

one third White Clover (Trifolium repens)

2. Contractor’s Quality Plan 2.1 Health and Safety Compliance Notice

Health and Safety Compliance Notice 2.1.1. This notice aims to:

foster a responsible attitude towards occupational health and safety on the part of all Contractors (including subcontractors) and their employees (personnel) undertaking work for the Principal (NZTA);

ensure compliance with relevant worksite safety laws especially the Health and Safety

in Employment Act 1992 (as amended from time to time), its regulations and any relevant health and safety codes of practice and guidelines issued by the Department of Labour.

2.1.2 The nature of the work undertaken on behalf of the Principal means that Contractors may

frequently be exposed to hazardous situations which require systems and procedures to eliminate, isolate or minimise the risk of harm to personnel and/or motorists.

2.1.3 All Contractors must observe the provisions of the Health and Safety in Employment Act

1992, its regulations and any relevant codes of practice and guidelines issued by the Department of Labour in accordance with the Act. Contractors must ensure:

a. all practicable steps are taken to provide a safe working environment and facilities for

all personnel (both in terms of the physical work environment and “non-physical” factors such as stress and fatigue);

b. Work procedures do not lead to personnel being exposed to hazards in and around the

place of work; c. procedures are developed for effectively managing emergencies that may arise at the

place of work. This should include both health and safety and environmental contingency plan development;

d. appropriate steps are taken for systematically identifying existing and potential new

hazards and subsequently reassessing those hazards; e. all practicable steps for controlling hazards are taken using the eliminate, isolate and

minimisation hierarchy (including the assessment, control, monitoring and review of existing and any new hazards);

f. adequate information, training, competency and supervision processes are in place to

ensure that personnel are able to work safely – this should include all work process, plant, equipment, and materials and, where appropriate, consideration given to those personnel to whom English is a second language. Training and competency records must be maintained;

g. all workplace accidents and incidents are reported, recorded and investigated to

determine root causes with effective corrective and preventative actions being implemented and monitored;

Appendices

2 2.1 Health and Safety Compliance

h. all Department of Labour requirements for “serious harm” injuries are reported within

the regulated timeframes – these must also be reported to the Principal’s Contract Representative;

i. the Principal’s Contract Representative is advised of any prohibition, improvement or

infringement notices issued by the Department of Labour. 2.1.4 If it is impracticable to eliminate or isolate significant hazards minimisation controls must

be implemented such as:

protective equipment and clothing safety equipment signage inspections, checks, audits and reviews

2.1.5 Contractors must ensure they comply with the NZTA’s Code of Practice for Temporary

Traffic Management. 2.1.6 Where required by the Principal, the Contractor must develop and submit a Contract

Health & Safety Management Plan, Traffic Management Plan and Environmental Management Plan for the contract / project works.
