1.1 Contract Description

This PSMC is for network management and maintenance of Length km (Lane length lane.km) of state highway within Transit New Zealand’s Region Region No., including list of SH included in network.

PSMC’s consist of a single contract for the provision of all products and services associated with state highway network maintenance, and replacing the traditional two tier multiple contract system predominantly in use elsewhere in the state highway network. It seeks to maximise the skills, expertise, innovation and systems of the roading industry to provide better outcomes and thus better value for money.

Fundamental to the PSMC concept is the need for a cooperative approach by the contracting parties. The conditions of contract seeks to remove the traditional adversarial relationship between Principal, consultant and contractor.

The PSMC is a lump sum contract. The tendered lump sum includes all costs to:

a) bring the Assets up to the contracted standard;

b) ensure the Assets comply with safety standards as they may change;

c) manage the integrity of the Assets through a cost effective long term network management and maintenance strategy; and

d) provide all inspection, identification, programming, prioritization and delivery of maintenance services necessary to achieve and demonstrate compliance with the Performance Criteria.

Monthly payments will be made to the Contractor for the Services throughout the term of the Contract, in accordance with the Basis of Payment. Payment is independent of actual works and services provided but may vary subject to adjustments provided for in the Contract Documents.

The Contractor is required to implement a system to monitor its performance and to demonstrate compliance with the Performance Criteria throughout the term of the Contract sufficient to stand scrutiny under review by the Superintendent or those nominated by the Superintendent. The Superintendent will also review the Contractor’s systems, procedures and records and may inspect the Assets to ensure the Performance Criteria are achieved. The Principal, at its cost, may contract with an independent party to conduct formal audits of the Contractor’s performance, annually or as otherwise required by the Superintendent.

Innovation is strongly encouraged under PSMC. The Contractor is expected to develop innovative ways of providing the Services and achieving the Performance Criteria.




A risk is an uncertain event which when it occurs, may have a material effect on the extent of the Services to be performed by the Contractor or on the cost to the Contractor of performing the Services. The Principal is seeking to achieve price certainty with regard to the PSMC. In this regard the Principal seeks to allocate risks to the party best able to manage it. Except where explicitly stated to the contrary in Appendix 1.1, the Contractor bears all risk in the lump sum tendered price.

1.1.3 Contract Outcomes

The Principal’s overall objective to provide a safe and efficient state highway network with the highest level of availability to road users and which satisfies stakeholder expectations is underpinned by eight outcomes.

The outcomes are:

a) Safety – Foster a network for road users and to support innovation in the development of techniques that: • manage traffic safely • provide road users with realistic perceptions of danger • provide consistent, safe and forgiving road environment with no surprises for

road users • provide a safe working environment for maintenance and construction activities

b) State Highway Protection - <<Monitor>> or <<Limit and rationalise>> accessways to protect the efficiency of the state highway network and control signs, glare/lighting and vegetation

c) Environment and Aesthetics - To avoid, remedy or mitigate, as far as possible, the adverse effects of highway maintenance and construction activities and road use on the environment

d) Asset Management - Optimise long term road maintenance to achieve desirable long term condition

e) Preventive Maintenance - Protect the long term reliability of the highway by proactive and innovative preventive maintenance




f) Contract Delivery - Use a systems approach to deliver the core needs of Transit New Zealand within the lump sum

g) Culture - Encourage a co-operative environment for all parties involved in the Contract to achieve the necessary outcomes

h) Services - Improve reliability of travel, minimise travel disruptions and keep customers informed of Transit New Zealand’s business.

1.1.4 Specific Requirements

The Performance Criteria which underpin the outcomes are described in Maintenance Specification, Sections 2 – 5 inclusive. They include the:

a) Management Performance Measures, (see Maintenance Specification, Section 2)

b) Key Performance Measures, (see Maintenance Specification, Section 3)

c) Operational Performance Measures, (see Maintenance Specification, Section 4)

d) Compliance Monitoring, (see Maintenance Specification, Section 5)

1.2 Limit of Works

Appendix 1.2 defines the Limit of Works in tabular and graphical form.

The Limit of Works consists of No. of sub-networks sub-networks. Service levels for Key Performance Measures and Response Times for Operational Performance Measures vary for each of the No. of sub-networks sub-networks.

Guidance Note: Generally three or four sub-networks will provide the right balance between describing the different needs of the sub-network and administrative burden. Five sub-networks may be required for networks with extremely diverse characteristics.

The Principal has Memoranda of Understanding with each of the territorial authorities prescribing limits of responsibility. In the event that there is no Memorandum of Understanding or a Memorandum of Understanding exists but does not cover a particular thing or Service then the limits of responsibility shall be specify principles or reference document. The Contractor is responsible for fulfilling all of the obligations assigned to Transit New Zealand in these documents.

Notwithstanding the above, the Limit of Works is further described by the following:

a) where the existing state highway is located only partly within the legal road reserve, the Limit of Works shall be defined by the existing fence line, the top of a cut batter or




toe of a fill batter, whichever is of greater offset from the road centreline but extending to the inlet or outlet structures of any culverts under the road

b) the Limit of Works with respect to carriageway lighting shall extend to the back of the montrose box

c) Consultant to list other specific Limit of Works definition

To avoid implying Transit New Zealand acceptance of unofficial or illegal crossings, the Contractor must not surface for any distance down a vehicle access or crossing intersecting with the state highway, unless that vehicle access is a local road or minor side road constructed specifically for the use of the general public.

Appendix 1.3 lists the known and current land entry agreements that have been made for access into adjoining properties to complete routine maintenance work. The Contractor must comply with the specific requirements of each agreement.

1.3 Handover and Handback

The existing network maintenance and management contracts include provision for total responsibility to be transferred to the Contractor on the Commencement Date with a requirement for one calendar months notice to the incumbent consultants and contractors.

The Principal will be responsible for negotiating with all incumbent contractors and consultants regarding handover of the Assets to the Contractor.

The following lengths of state highway have unresolved liability issues with respect to pavement design life:

a) Consultant to list by SH and RP

b) Consultant to list by SH and RP

c) …

Each of these sections will be separately handed over to the Contractor once the relevant outstanding liability issues have been resolved. At the time of handover, these sections will have a 25 year pavement design life.

The incumbent network maintenance contractor utilises various equipment and material including:

a) temporary signs and signals;

b) fencing; and




c) miscellaneous tools and materials.

Any equipment or material that is the property of the Principal will be made available to the Contractor within two weeks of the Commencement Date at no charge.

The Contractor shall ensure continuity of all temporary works that are provided to mitigate a safety hazard.

All temporary signs, signals and fencing in the Contractors possession, that are being used to provide the Services at the completion of the Contract, shall become the property of the Principal. No payment for such equipment and materials will be made to the Contractor.

1.4 Ownership

Although ownership of the Assets remains with the Principal, the Contractor is encouraged to develop a sense of ‘ownership’.

The Contractor is expected to proactively assume responsibility on the Principal’s behalf for the implementation of Transit New Zealand policies, particularly in the areas of information management, network controls and safety.

The Contractor shall pursue a strategy of proactive routine preventive maintenance to minimize potential capital works needs due to lack of maintenance. The Contractor shall pursue a strategy of proactive routine minor safety work to minimize safety hazards.

The Contractor shall maintain a responsibility for ensuring safety, good public relations and compliance with the Principal’s standards in areas of the network where other consultants are concurrently working. Generally, the Contractor will raise any concerns initially with the other consultant, but, in urgent situations, the Contractor shall take immediate action to ensure public safety or protect the Principal’s interests. The Principal will enter into separate professional services contracts for services which do not fall within the Services, some management related professional services, and for the implementation of some aspects of the National Roading Programme. Those contracts may include, but are not limited to the activities excluded from the Services as described in Maintenance Specification, Clause 1.1.1.

1.5 Cost Recovery

The Contractor is responsible for the day to day management of network control as described in Maintenance Specification, Clause 2.8. The cost of these activities is included in the lump sum.

Where the Principal would normally be entitled to recover its costs in respect of any network control activity, the Contractor may attempt to recover its costs for performing




these activities from parties other than the Principal. The Principal shall be under no obligation to assist in such cost recovery other than to provide the Contractor with delegated authority to seek recovery.

Cost recovery for damage to Assets shall be in accordance with Conditions of Contract, Clause 1.5.12.

1.6 Pro-active Preventive Maintenance and Minor Safety Works

Pro-active preventive maintenance and minor safety works are considered to be in the best interests of both the Principal and the Contractor.

Where responsibility for a particular item of preventive maintenance or minor safety work has not been clearly established prior to award of the Contract, responsibility shall be allocated in keeping with the intent of the agreements established for other items of preventive maintenance or minor safety works as appropriate.

Completed preventive maintenance and minor safety works (both routine and non-routine) shall form part of the Assets and be maintained as part of the Services.

1.6.1 Routine Work

Routine preventive maintenance works are timely effective measures performed as part of the Services, focused on minimizing consequential damage, inconvenience to motorists and future costs. Such preventive maintenance works are strongly encouraged by the Principal. It is envisaged such work may include clearing culvert inlets and outlets, diverting of surface water away from areas of instability, grassing down and like measures.

Routine minor safety works are timely effective measures performed as part of the Services, focused on minimizing safety hazards. They include, but are not limited to, all safety maintenance recommendations identified by crash reduction studies and minor safety works recommendations identified by crash reduction studies, to the extent that they are included within the Services as described by the Variation Benchmarking Guidelines in Appendix 1.13. Such minor safety works are strongly encouraged by the Principal. It is envisaged such work may include relocating or adding new regulatory, warning and advisory speed signs and chevron markers, relocation of obstructions, addition of new pavement markings and like measures.

1.6.2 Non-routine Work

Non-routine preventive maintenance are those works defined as Work Category 20 in Transfund New Zealand’s Programme and Funding Manual. They are required to protect the serviceability of the roading network and to minimise the threat of road closure. It is envisaged such work may include gravity retention walls, horizontal drainage of slips, toe




weighting, soil conservation planting, the use of geogrid and geotextiles, rip rap protection and in stream channel works and like measures.

The Contractor shall maintain a comprehensive list of all non-routine preventive maintenance opportunities within the Limit of Works, not included within the Services as described by the Variation Benchmarking Guidelines in Appendix 1.13. Reports justifying each such preventive maintenance opportunity as eligible for funding additional to the lump sum, shall periodically be referred to the Principal for a decision.

Non-routine minor safety works are those works defined as Work Category 60 in Transfund New Zealand’s Programme and Funding Manual, Clause 2.2.3. They consist of all capital works recommendations identified by crash reduction studies and minor safety works recommendations identified by crash reduction studies, to the extent that they are excluded from the Services as described by the Variation Benchmarking Guidelines in Appendix 1.13. It is envisaged such work may include easement of curves and backdrop planting to curves and like measures.

The Contractor shall maintain a database providing the most complete representation possible of crashes within the Limit of Works. The Contractor shall include in the Safety Management Intervention Plan a comprehensive list of non-routine minor safety works. Reports justifying each such minor safety work opportunity as eligible for funding additional to the lump sum, shall periodically be referred to the Principal for a decision.

1.7 Incident Response

The Contractor is required to provide a 24 hour, seven day a week timely incident response service.

Emergency Work, as defined in the Transfund New Zealand Programme and Funding Manual, other than Incident Response and to the extent that it is a risk allocated to the Principal in Appendix 1.1, shall be treated as additional works in accordance with Maintenance Specification, Clause 1.9.

1.8 Additional Works

Additional works shall be Directed in accordance with Conditions of Contract, Clause 1.7.2.4 such that nothing in the Contract prevents the Principal from engaging another contractor to perform work or services, which if carried out by the Contractor, would require a variation of the Services.

The Contract provides discretion to the Superintendent with respect to the execution of additional works by the Contractor up to a total cost of $<<400,000>> in respect of each discreet project involving additional works. To this extent where the Superintendent assesses a benefit exists to the Principal, which may take the form of:




a) expedited work;

b) increased efficiency; and/or

c) reduced administration costs,

the Superintendent may at his sole discretion Direct additional works which do not form part of the Services.

1.9.2 Maintenance Responsibility

The Contractor is required to manage all activities within the Limit of Works to the extent that it is necessary to ensure the safe and efficient movement of traffic at all times, and that the quality of the Assets are not compromised by the activity or inactivity of others.

The presence of other contractors does not relieve the Contractor of its obligations to maintain the Assets according to the Contract Documents, unless the presence of other contractors directly affects the Services.

The Contractor will not be responsible for:

a) maintenance of those Assets included within the limits of a capital works project being undertaken within the Limit of Works under another contract between the date of possession of site and the date of practical completion of those other contracts.




b) maintenance arising from defective workmanship or materials of any Assets which have been upgraded as a capital work under other contracts and, for the time being, are the maintenance responsibility of another contractor between the date of practical completion and the end of the defects liability period of those other contracts.

A joint inspection, conducted by the Superintendent and the Contractor on practical completion of other contracts, will identify any particular maintenance or omission responsibilities of the other contractor that may exist at the date of practical completion. The Contractor will be responsible for ongoing day to day and periodic maintenance to any assets that lie within the limit of works of other contracts between the date of practical completion and the end of the defects liability period of those other contracts.

If invited, the Contractor must participate in a Stage 4 Safety Audit conducted on practical completion of other contracts, to identify any particular safety-related responsibilities of the other contractor that may exist at the date of practical completion. This Safety Audit may be performed in parallel to the above joint inspection conducted by the Superintendent and the Contractor.

A joint inspection, conducted by the Superintendent and the Contractor at the end of the defects liability of other contracts, will identify any particular maintenance or omission responsibilities of the other contractor that may exist at the end of the defects liability period.

3 Key Performance Measures


3 Key Performance Reports

3.1 Definition

Key Performance Measures reflect the overall condition of the primary Asset, the pavement. The Contractor must comply with the following Key Performance Measures.

Contract Standard, in respect of Key Performance Measures, means the minimum standard the Contractor is required to comply with at the end of each year of the Contract. Unless stated otherwise within the Contract Documents, all data required to demonstrate compliance shall have been collected and reported in accordance with Table 3.3.1.

Table 3.1.1: Key Performance Measure Data Collection and Reporting Data Collection Due Report Due

Benchmarking Date Month Year Date Month Year

Compliance (Year 1) 31 March Year 30 June Year









Compliance (Year 10) Date Month Year Date Month Year

Guidance Note: The Consultant should specify the date for Benchmarking data collection giving due consideration to the Commencement Date and the climatic limitations of the equipment. The Consultant should specify the date for Year 10 data collection giving due consideration to the Termination Date and the climatic limitations of the equipment. Reporting dates should be a maximum of three months from the completion of data collection. The Year 10 report should be delivered prior to the Termination Date.

3.2 Key Performance Measure Year 0 Benchmark

The Contract Standards for Maximum Percent with Roughness > Threshold, Maximum Percent with Mean Texture Depth < Threshold (MPD), Maximum Percent with Mean Texture Depth > Threshold (MPD) and Skid Resistance, as specified in Maintenance Specification, Tables 3.3.2, 3.4.3, 3.4.4, 3.4.5, 3.4.6, 3.5.1, 3.5.2, 3.5.3, 3.5.4 and 3.5.5




respectively, are fixed criteria and are not subject to adjustment based on the results of any benchmark survey.

The Contract Standard for Surfacing Life Index, as specified in Maintenance Specification, Table 3.7.1, shall be benchmarked by recalculation as at the Commencement Date to reflect the full extent of all resurfacing completed up to that date.

The Contract Standards for Roughness – Mean NAASRA, Texture – Minimum Mean Texture Depth and Rutting, as specified in Maintenance Specification, Tables 3.3.1, 3.4.1, 3.4.2 and 3.6.1 respectively, are subject to adjustment based on the results of the high speed data collection survey performed to benchmark the condition of the Assets in accordance with Maintenance Specification, Clause 5.2.2. The Contract Standard for Structural Condition Index, as specified in Maintenance Specification, Table 3.8.1, is subject to adjustment based on the results of the falling weight deflectometer survey performed to benchmark the condition of the Assets in accordance with Maintenance Specification, Clause 5.2.2. The adjustment for each Key Performance Measure in each sub-network shall be determined as follows:

a) the Management Board agree the benchmark value

b) the benchmark value shall replace the Year 0 value

c) the Year 1 to 10 values shall be adjusted so as to maintain the same numerical difference in value from the Year 0 value

This same benchmark process shall apply whether the Contract Standards were those specified in the Tender Documents or alternative values specified in the Contractor’s Tender and subsequently accepted.

The following examples are provided for the avoidance of doubt:

3.2.1 Example 1: Tender Documents

The Contract Standard for Roughness – Mean NAASRA Key Performance Measure for sub-network 1 is defined in the Tender Documents as Value.

The Roughness – Mean NAASRA Key Performance Measure is subject to benchmarking adjustment and a value of <<Value + 0.9>> is determined through the benchmark high speed data collection and accepted by the Management Board. In this event the Contract Standard would become <<Value + 0.9>>.

3.2.2 Example 2: Contractor’s Tender

The Contractor’s Tender offers to reduce the Roughness – Mean NAASRA Key Performance Measure in sub-network 1 to <<Value – 2.4>> by Year 10 based on the initial Year 0 value of Value.




Again a value of <<Value + 0.9>> is determined by the benchmark high speed data collection and accepted by the Management Board. In this event the Year 0 value becomes <<Value + 0.9>> and the Year 10 value becomes <<Value – 1.5>>. All other values offered in the Contractor’s Tender for Years 1 to 9 would be similarly adjusted.

3.3 Roughness

Roughness information is collected by the Contractor’s annual high speed data survey. Details of the calculation methods for roughness Key Performance Measures are included in Appendix 3.1.

3.4.4 Requirement to Treat Surface Texture

Contract Standard – Where the texture values generated from the high speed data for:

• chipseal surfaces, or any surface where steady reduction of the macro texture is a normal consequence of the aging of the surface, are less than the threshold level of <<0.5>>mm (MPD); and/or

• asphaltic surfaces where the macro texture remains essentially constant, are less than the threshold level of <<0.5>>mm (MPD) and have a site crash history,

the length shall be treated such that;

• it shall be made safe; and

• within 2 months of delivery of the high speed data the Minimum Mean Texture Depth (see Appendix 3.2.1) of the length is above <<0.7>>mm (MPD) for urban roads and <<0.9>>mm (MPD) for rural roads.

Treatments to the road surface texture should generally be long term repairs. Where a treatment is not expected to last for at least 12 months, a monitoring programme shall be implemented by the Contractor to ensure additional maintenance is carried out as soon as the surfacing falls below the threshold levels of <<0.5>>mm (MPD). Where a new surfacing layer is placed the aggregate shall have a Polished Stone Value as required by Transit New Zealand’s T/10:1999 Standard Specification.

Where the road cannot be successfully repaired due to weather constraints, a sign shall be erected to make the road safe. In this event, the surfacing must be repaired and the sign removed by the following first of November.

3.5 Skid Resistance

Skid resistance information is collected by the Contractor’s annual high speed data survey. Details of the calculation methods for skid resistance Key Performance Measures are included in Appendix 3.3.

The Site Categories are in terms of Transit New Zealand’s T/10:1999 Standard Specification. They define the types of locations applying to each Site Category and the minimum sideways coefficient for the location.

It may be necessary to source chip from outside the Limit of Works in order to obtain a Polished Stone Value and Aggregate Crushing Value adequate to achieve compliance with this Key Performance Measure.

• it shall be made safe; and

• within two months of delivery of the high speed data survey the skid resistance of the length is above the Investigatory Level specified in Transit New Zealand’s T/10:1999 Standard Specification.

Treatments to the road surface should generally be long term repairs. Where a treatment is not expected to last for at least 12 months, a monitoring programme shall be implemented by the Contractor to ensure additional maintenance is carried out as soon as the surfacing falls below the Investigatory Level specified in Transit New Zealand’s T/10:1999 Standard Specification. Where a new surfacing layer is placed the aggregate shall have a Polished Stone Value as required by Transit New Zealand’s T/10:1999 Standard Specification.

Where the road cannot be successfully repaired due to weather constraints, a sign shall be erected to make the road safe. In this event, the surfacing must be repaired and the sign removed by the following first of November.

4 Operational Performance Measures



4.1 Definition

Operational Performance Measures reflect the road users expectation about the network’s day to day serviceability. For each Operational Performance Measure the Contractor must comply with both the Contract Standard and Response Time separately, as defined below. The Contractor is required to develop and implement a compliance monitoring system in accordance with Maintenance Specification, Clause 5.3.1 to demonstrate that both Contract Standards and Response Times are being achieved.

Section means the width from the state highway centreline to the Limit of Works over the specified length, irrespective of the width of the carriageway. The centreline itself shall be included in the direction of increasing route position e.g. a 1km Section in the direction of decreasing route position is the width from the state highway centreline (excluding the centreline itself) to the Limit of Works over a 1km length of highway. For the purposes of determining compliance with the Contract Standard, Sections shall not overlap and shall be consecutive. The length of a Section is specified by individual Operational Performance Measure in Maintenance Specification, Clauses 4.2 to 4.18.

Contract Standard, in respect of Operational Performance Measures, means the minimum standard the Contractor is required to comply and report compliance with at all times, regardless of whether defects have been programmed for repair within the Response Time or not. Where compliance is based on a percentage of Sections, multiple non-compliances with a single Operational Performance Measure within a single Section shall only count as one non-compliant Section. Compliance with the Contract Standard is required in each and every separate sub-network. The Management Board’s approval of an inspection procedure, in accordance with Maintenance Specification, Clause 5.3.5, will be a key component in the demonstration of compliance with the Contract Standards.

Response Time means the time in which the Contractor must rectify any particular instance of a defect, regardless of whether or not compliance is being achieved with the Contract Standard. Unless specifically requested otherwise by the Superintendent, the Contractor is required to report compliance with Response Times only for Incident Response.

The Superintendent may choose to review the Contractor’s compliance with Response Times, for example, by recording the route positions of potholes and repeating the inspection later to determine if those specific potholes have been repaired within the Response Time.

Notwithstanding any of the Response Times specified below, if any defect or problem arises that, in the opinion of the Superintendent or the Contractor’s qualified traffic safety personnel, constitutes a potential safety hazard, the defect or problem shall be rectified as soon as possible but within 24 hours.




4.2 Pavement

Pavement faults are generally described in Transit New Zealand’s C Series Standard Specifications.

Consistent texture is defined as:

• having an Average Least Dimension within 0.5mm for Grade 1 to Grade 4 chip

• the same grade for Grade 5 and Grade 6 chip

Shoves and heaves are defined in Appendix 4.1.1

Edgebreak is defined as seal loss greater than 100mm from nominal seal edge or encroaching onto the painted edge line

4.5 Bridges

Bridges are defined as any structure with a waterway over 3.4m2. Any structure with a waterway up to 3.4m2 is defined as a stormwater structure and is maintained in accordance with Maintenance Specification, Clause 4.4. Bridges also include some underpasses and overbridges.

Routine bridge maintenance typically involves all work associated with the maintaining the condition and appearance of these structures. It excludes work that affects the load carrying capacity of the structure. Examples of routine bridge maintenance are works arising from Superficial Inspections, as defined in Appendix 13.3 of the Transit New Zealand Bridge Inspection and Maintenance Manual, including but not limited to:

a) keeping all components clean

b) removing detritus from decks, drainage systems, bearings, deck joints etc and maintaining in a serviceable condition

c) repairing damaged guardrails and handrails

d) maintaining: • <<painted parapets at bridge approaches to provide clear delineation>> • waterway and clearing debris from the structure

e) reporting all damage and deterioration which may impact on structural performance to the Principal’s Bridge Consultant.

4.7 Vegetation Control

Appendices 4.4 and 4.5 set out the location and extent of all known vegetation control requirements. The control types referred to in these Appendices are:

a) Type 1 Control – this standard applies to nominated areas shoulders, medians, traffic islands and highway verges within urban areas.

b) Type 2 Control – this standard applies to rest areas.

c) Type 3 Control – this standard applies to rural state highways.

d) Type 4 Control – this standard applies to sight benches on rural state highways and large vegetated areas.

e) Type 5 Control – this standard applies to the control of vegetation around edge marker posts, signs, sign posts, bridge end and culvert markers, culvert ends, headwall, guardrails, sight rails, surface water channels, kerb and channel, weighpits, side drains, culvert waterways, bridge abutments and rest area furniture.

The extent of control is described in Clause 3.6 of Transit New Zealand’s C21:1997 Standard Specification. All sealed surfaces must be vegetation free at all times.

The term near vegetation-free, as used in Transit New Zealand’s C21:1997 Standard Specification, means:

• vegetation does not exceed 100mm in height

• the method of control:

i) does not result in vegetation burn off or the creation of potential burn off;

ii) maintains the free flow of water to discharge points;

iii) prevents mechanical damage to roadside furniture such as signs, marker posts, guardrails, etc; and

iv) enables missing or damaged roadside furniture such as signs, marker posts, etc to be identified.

f) Type 6 Control – this standard applies to the control of all plant pests within the Limit of Works including stockpile sites. Plant pests shall be controlled in accordance with the policy specified in Clause 1.6.6 of the Transit New Zealand State Highway Control Manual.




g) Type 7 Control – this standard applies to vegetation control within planted areas. Planted area maintenance includes:

• weeding of planted areas

• raking areas of bark and gravel chips

• trimming and /or pruning of trees, shrubs and ground cover to maintain:

• all plants in a healthy condition

• sight distances, see Appendix 4.5

• replacing dead plants with similar species.

All planted areas and adjacent pavement to a distance of 0.5m from the kerb face must be maintained frees of weeds and litter so they are neat and tidy at all times.

In cases where flying debris represents a safety hazard to road users, vegetation control must be performed using vertical flail type mowers.

ii) sub-network <<4>> – mobilise within ½ hour, establish and start work on site within 1 hour

4.19 Other Operational Performance Measures

The CQP must state all other Operational Performance Measures that apply.


5 Compliance Monitoring



5.1 Objectives

The objectives of the compliance monitoring system are to:

a) benchmark the initial condition of the Assets at the beginning of the Contract to:

• set the Contract Standards for the Key Performance Measures identified in Maintenance Specification, Clause 3.2

• determine the period within which the Contractor is required to bring the Assets into full compliance with the Operational Performance Measures (see Maintenance Specification, Clause 5.2.3);

b) monitor the achievement of the Performance Criteria. These are:

• Management Performance Measures

• Key Performance Measures

• Operational Performance Measures; and

c) provide the Principal with security that its outcomes are being achieved.

5.2 Benchmark Condition

5.2.1 Management Performance Measures

The Contract Standards for all Management Performance Measures are fixed criteria and shall not be subject to adjustment based on the results of any benchmarking survey.

5.2.2 Key Performance Measures

By the date specified in Maintenance Specification, Clause 3.1, the Contractor shall perform a 100% sample high speed data collection survey in accordance with <<the Data Collection Specification>> (see Appendix 1.7).

By the date specified in Maintenance Specification, Clause 3.1, the Contractor shall perform a 100% sample falling weight deflectometer survey in accordance with <<the Data Collection Specification>> (see Appendix 1.7).

The Principal may, at its discretion, engage others to perform similar parallel surveys.

By the date specified in Maintenance Specification, Clause 3.1, the Contractor shall process, interpret and present the results to the Management Board in the form of a Benchmarking Report in accordance with Appendix 2.1.3. The Management Board shall satisfy itself as to the accuracy and validity of the survey results and shall then decide the




Contract Standards for the relevant Key Performance Measures in accordance with Maintenance Specification, Clause 3.2.

The Contract Standards for all other Key Performance Measures shall be as specified in the Contract Documents.

5.2.3 Operational Performance Measures

By the date nominated in the Contractor’s Tender, the Contractor shall perform a 100% inspection of all Assets associated with Operational Performance Measures within the Limit of Works, to establish the extent to which the Assets comply with the Operational Performance Measures.

The Superintendent may, at his discretion, conduct a similar parallel inspection or engage others to perform a parallel inspection.

Within two months of completion of the Operational Performance Measure benchmarking inspection, the Contractor shall process, interpret and present the results to the Management Board in the form of a Benchmarking Report in accordance with Appendix 2.1.3. The Management Board shall satisfy itself as to the accuracy and validity of the survey results and shall then decide the period within which the Contractor shall bring the condition of the Assets into full compliance with the Operational Performance Measures, and any Contract Standards that apply to any staging in that period. The Management Board shall take note of the Principal’s requirement to limit this period and shall only set it above three months where such a timeframe would be unachievable. Non-compliance notices shall only be issued in this period if the Contractor fails to comply with safety related Response Times or agreed staging requirements (see Maintenance Specification, Clause 5.4).

5.3 Compliance Monitoring

5.3.1 Contractor’s Compliance Monitoring System

The Contractor must develop, implement and manage a compliance monitoring system that:

a) objectively assesses their compliance with each of the Performance Criteria;

b) monitors and reports compliance with the Contract Standard specified for each of the Performance Criteria; and

c) ensures appropriate corrective actions are developed, implemented, actioned and verified.




The Contractor’s compliance monitoring system must describe the process for assessing compliance for each of the Performance Criteria. This includes:

a) the personnel responsible for:

• implementing and managing the system

• completing the compliance assessment

b) the inspection methodology to be used to demonstrate compliance with the Operational Performance Measures in accordance with Maintenance Specification, Clause 5.3.5;

c) assessing, determining and demonstrating the percentage compliance with the Contract Standard specified for each of the Performance Criteria, where appropriate;

d) recording and reporting results;

e) developing and implementing appropriate corrective actions; and

f) making all information available for the Superintendent to audit the system.

The Contractor is required to perform its own data collection surveys to demonstrate compliance with the Performance Criteria, independent of any similar surveys performed by the Principal.

Except where otherwise provided in the Contract Documents, the Contractor’s inspections and compliance monitoring system does not provide a direct input into the non-compliance system described in Maintenance Specification, Clause 5.4. As such, a non-conformance identified by the Contractor will not necessarily attract a non-compliance notice in accordance with Maintenance Specification, Clause 5.4, where the Contractor’s non-conformance resolution has effectively addressed any systematic or procedural shortfall.

5.3.2 Superintendent’s Review

The Superintendent will review the Contractor’s systems, procedures and records to determine their effectiveness in ensuring that the Contract Standards, Response Times and Delivery Times are being achieved.

The Superintendent’s reviews do provide a direct input into the non-compliance system described in Maintenance Specification, Clause 5.4.

Superintendent’s reviews may concentrate on areas where the Contractor’s compliance monitoring system has identified a systematic failure. However, the Superintendent may review the Contractor’s procedures and work activities and may conduct specific Asset inspections at any time.




The Superintendent’s reviews will in no way limit the Contractor’s responsibility to develop, implement and manage a Contractor’s compliance monitoring system.

5.3.3 Management Performance Measures

For each Management Performance Measure, the Contractor must demonstrate compliance with the Contract Standards and Delivery Times. Compliance is required in respect of each discreet deliverable.

The Contractor’s compliance monitoring system shall record the timeliness of deliverables for each Management Performance Measure.

The Superintendent, or others engaged by the Superintendent for this purpose, shall review the standard and timeliness of deliverables.

5.3.4 Key Performance Measures

For each Key Performance Measure, the Contractor must demonstrate compliance with the Contract Standards. Compliance is required in respect of each measure in each sub-network. The Compliance Reports do provide a direct input into the non-compliance system described in Maintenance Specification, Clause 5.4.

5.3.5 Operational Performance Measures

For each Operational Performance Measure, the Contractor must demonstrate compliance with the Contract Standards and Response Times. Compliance is required in respect of each measure in each sub-network.

The Contractor’s compliance monitoring system shall record achievement of Contract Standards and Response Times (where required) for each Operational Performance Measure.

Within two months of completion of the Operational Performance Measure benchmarking inspection, in accordance with Maintenance Specification, Clause 5.2.3, the Contractor shall present to the Management Board an inspection procedure for each Operational Performance Measure proposed to demonstrate compliance with Contract Standards at any time throughout the duration of the Contract.

The Management Board shall satisfy itself to the extent that the proposed inspection procedure will satisfactorily demonstrates compliance with Contract Standards for each Operational Performance Measure and shall decide the inspection methodology to be adopted. The following is provided as a guide to the Management Board:

Where an Operational Performance Measure Contract Standard depends on a percentage non-compliance, for example ‘No more than 5% of the number of 100m Sections…’ the inspection methodology for compliance demonstration as part of the Contractor’s




compliance monitoring system or Superintendent’s reviews may be based on any of the following inspection methodologies:

a) 100% Asset inspection of the total population:

Under this inspection methodology the Management Board shall decide the frequency at which a 100% Asset inspection of the total population is undertaken.

Following the 100% inspection of the total population, the requirement for the demonstration of compliance with the specified minimum Contract Standard (CS%) is:

%% CSP ≥ Equation (a) where: Z = the total number of units in the population z = the total number of units inspected that have no defects

P% = total population % compliant = 100×Zz

Guidance Note: The following example should be reworked using data specific to the contract e.g. sub-network length, no. of lanes, etc

The following example is provided for the avoidance of doubt:

For shoulder potholes the Contract Standard is defined as ‘No more than 5% of the number of 100m Sections with one or more defects’ so that CS% = 95%.

Sub-network 2 is 59.2km in length with the total number of 100m Sections in the population Z = 59.2 x 2 x 10 = 1184.

From equation (a) the requirement for the demonstration of compliance becomes:

%951001184

≥×z

and rearranging for z:

1125118495.0 =×≥z

In this case, compliance with the Contract Standard means that at least 1125 of the 1184 - 100m Sections shall have no defects in terms of shoulder potholes at each inspection.

b) Statistically Significant Asset Sample

Under this inspection methodology the Management Board shall decide the size of a randomly selected sample from the total population, which the Management Board




considers will represent satisfactorily the total population. The Management Board shall also decide the frequency at which the inspection of the sample is undertaken.

The requirement for the demonstration of compliance with the specified minimum Contract Standard (CS%) is then determined in accordance with Equation (a) above, by substituting the sample population % properties for the total population properties.

Guidance Note: The following example should be reworked using data specific to the contract e.g. no. of lanes, etc

The following example is provided for the avoidance of doubt:

Continuing from the example in a) for shoulder potholes the Management Board decides that a randomly selected 10km of sub-network 2 is a statistically significant sample to represent the total population such that the total number of 100m Sections in the sample population Zs = 10 x 2 x 10 = 200.

From Equation (a), the requirement for the demonstration of compliance becomes:

%95100200

≥×sz

and rearranging for zs:

19020095.0 =×≥sz

In this case, compliance with the Contract Standard means that at least 190 of the 200 - 100m Sections shall have no defects in terms of shoulder potholes at each inspection.

c) Statistical Inference from Asset Sample

Using statistical inference the % compliance of the total population (P%) is estimated from the % compliance derived from a randomly selected sample from the total population (Ps%).

Under this methodology the Management Board shall decide the size of a randomly selected sample from the total population, however the sample is not necessarily required to be statistically significant . The Management Board shall also decide the frequency at which the inspection of the sample is undertaken.

As the sample properties generally do not exactly represent the properties of the total population a sampling error is considered. The larger the sample size the smaller the sampling error becomes and subsequently the closer the sample will represent the total population.




Through setting an upper and lower bound confidence limit to Ps%, it is possible to predict to a level of confidence, that P% falls within the bounds of Ps% +/- confidence interval. For the purpose of compliance demonstration an 85% confidence limit shall be used to set the width of the confidence interval.

For the Contractor’s compliance monitoring system to demonstrate that P% is greater than %CS the lower bound of the 85% confidence limit must be shown to be above the % CS such that the criteria for compliance demonstration becomes:

%%85% CSCLPS ≥− Equation (b)

where: ZS = the total number of units in the sample

zS = the total number of units inspected that have no defects

PS% = sample % compliant = 100xZz

and 1.44 is a constant which results from the assumptions of 85% confidence and the normal distribution of defects over the total population.



Continuing from the example in a) for shoulder potholes, a sample of 150 of the 100m Sections (ZS) are randomly selected from the total population of 1184 Sections. As a result it is found that 145 Sections (zS) have no shoulder potholes greater than 100mm in diameter or 50mm deep. From the sample results the % compliant (PS%) is determined as:

%7.96100150145% =×=SP

and the 85% Confidence Level (CL) as:

%11.2150

)7.96100(7.9644.1 =

−××=

From Equation (b), the criteria for the demonstration of compliance:




%95%56.94%11.2%7.96 <=−

is not achieved so that compliance has not been demonstrated in this case.

To illustrate the effect of increasing the sample size to reduce sampling error now consider the a scenario where the sample size is doubled to 300 Sections (XS) and the resulting % compliant (PS%) is as previously at 96.7% due to 290 Sections (xS) found to have no shoulder potholes greater than 100mm in diameter or 50mm deep.

The 85% CL becomes:

%49.1300

)7.96100(7.9644.1 =

−××=

From Equation (b), the criteria for the demonstration of compliance becomes:

%95%17.95%49.1%7.96 >=−

Clearly compliance has been demonstrated in this case.

Where the inspection procedure relies on statistical inference, a sufficient sample to permit the assumption of a normal distribution of defects over the total population is required.

Under the Superintendent’s review to demonstrate non-compliance of the total population from a random sample using statistical inference the upper bound of the 85% CI must be below the % CS such that the criteria for non compliance demonstration becomes:

%%85% CSCLPS ≤+ Equation (c)



Continuing from the example in a) for shoulder potholes, the Superintendent randomly selects 150 of the 100m Sections (ZS) from the total population of 1184 Sections where his review finds that 145 Sections (zS) have no shoulder potholes greater than 100mm in diameter or 50mm deep.

From the sample results the % compliant (PS%) is determined as:

%7.96100150145% =×=SP




and the 85% CL as:

%11.2150

)7.96100(7.9644.1 =

−××=

From Equation (c), the criteria for the demonstration of non-compliance becomes:

%95%81.98%11.2%7.96 >=+

In the previous example (with the same zS and ZS) the Contractor was unable to demonstrate compliance, but the Superintendent’s review has not conclusively demonstrated that the total population is non compliant. In this case a non-compliance notice would not be issued.

Now consider if six months following the previous audit the Superintendent performs another random 150 sample inspection however as a result of this audit only 135 Sections (zS) are found to have no shoulder potholes greater than 100mm in diameter or 50mm deep. From the sample results the % compliant (PS%) is determined as:

%90100150135% =×=SP

and the 85% CL as:

%53.3150

)90100(9044.1 =

−××=

From Equation (c), the criteria for the demonstration of non-compliance becomes:

%95%53.93%53.3%90 <=+

In this case the Superintendent’s review has demonstrated the total population to be non compliant and a non-compliance notice would be issued.

5.4 Non-Compliance System

5.4.1 System Description

The system is based on non-compliance notices which may be issued by the Superintendent in two forms:

a) major non-compliance notice

b) minor non-compliance notice




Prior to issuing a major non-compliance notice the Superintendent must present the circumstances under which the non-compliance notice is to be issued to the Management Board.

Following such presentation the process to be followed defining the requirements for issue of the major non-compliance notice shall be defined by the flowchart in Appendix 5.1.

A non-compliance notice can only be closed by the Superintendent. The Contractor must demonstrate, to the satisfaction of the Superintendent, that the conditions required to close the non-compliance notice have been fulfilled.

The number and status of both types of non-compliance notice shall be reported at every meeting of the Management Board.

The Principal may, at its sole discretion, terminate the Contract if:

a) three major non-compliance notices are open at any time; or

b) a Key Performance Measure for which a major non-compliance notice has been issued in accordance with Maintenance Specification, Clause 5.4.2 c) is not met within one year of the issue of the major non-compliance notice; or

c) the Contractor fails to perform the annual high speed data collection survey; or

d) the Contractor fails to perform the falling weight deflectometer survey in Years <<3, 6, 8 and 10>>; or

e) as provided for elsewhere in the Contract.

5.4.2 Major Non-Compliance

The following describes the circumstances in which a major non-compliance notice may be issued and closed out:

a) Multiple minor non-compliance notices

• Issued – at any time when a total of <<five>> minor non-compliance notices, whether related or not, are open.

Following the issue of such a major non-compliance notice, any further minor non-compliance notices that are issued shall contribute towards another major non-compliance notice regardless of whether any of the <<five>> minor non-compliance notices making up the preceding major non-compliance notice have been closed out.

• Closed out – when all <<five>> minor non-compliance notices comprising the major non-compliance notice have been closed out and the Performance Criteria to




which those minor non-compliance notices relate have been maintained for one year.

b) Failure to complete surveys

• Issued – when the Contractor has failed to complete the benchmarking surveys within the timeframes specified in Maintenance Specification, Clauses 5.2.2 and 5.2.3 or failed to complete the compliance surveys within the timeframes specified in Maintenance Specification, Clause 3.1.

An additional major non-compliance notice may be issued for every two months a survey has not been completed following the issue of the initial major non-compliance notice.

• Closed out – when the Contractor has presented the survey report to the Management Board and the Management Board has accepted the results.

c) Failure to deliver survey reports

• Issued – when the Contractor has failed to deliver the Benchmarking or Compliance Reports within the timeframes specified in Maintenance Specification, Clause 3.1.

An additional major non-compliance notice may be issued for every two months a report has not been completed following the issue of the initial major non-compliance notice.

• Closed out – when the Contractor has presented the report to the Management Board and the Management Board has accepted the results.

d) Failure to meet Key Performance Measures

• Issued – when the Contractor has failed to meet a Key Performance Measure by a margin greater or equal to that listed in Table 5.4.1.

Separate major non-compliance notices may be issued for every Key Performance Measure not met in each sub-network. For example, if the Roughness – Mean NAASRA Key Performance Measure is not achieved by a margin greater than the specified 2 NAASRA for both sub-networks 1 and 2, the Superintendent may issue two major non-compliance notices following the procedure specified in Maintenance Specification, Clause 5.4.1.




Table 5.4.1: Major Non-Compliance Tolerances for Key Performance Measures Key Performance Measure Tolerance

Roughness – Mean NAASRA <<2>> NAASRA

Roughness – Percent with Roughness > NAASRA Threshold <<1.00>>%

Texture – Minimum Mean Texture Depth <<0.20>>mm

Texture – Percent with Mean Texture Depth < Threshold <<0.20>>%

Texture – Requirement to Treat Surface Texture <<0>>

Skid Resistance – Percent with SFC < Threshold <<1.00>>%

Skid Resistance – Requirement to Treat Surface Skid Resistance <<0>>

Rutting – Percent with depth > 20mm <<0.25>>%

Surfacing – Minimum Annual Resurfacing Length <<10>>%

Structural Condition – Structural Condition m3 Overlay <<3>>%

Structural Condition – Minimum Annual Rehabilitation Length <<10>>%

• Closed out – when the Contractor has demonstrated to the satisfaction of the Superintendent that the Key Performance Measure has been met and, for the avoidance of doubt, not merely brought back within the tolerance specified in Table 5.4.1.

5.4.3 Minor Non-Compliance

A minor non-compliance notice may be issued in the following circumstances:

a) Failure to meet Management Performance Measures

• Issued – when the Superintendent determines that the Contractor has failed to comply with a Management Performance Measure Contract Standard or Delivery Time, other than Benchmarking or Compliance Reports.

Separate non-compliance notices may be issued for each occasion of late delivery and for each instance of non-compliance with the Contract Standards, for any meeting, report, management plan or for any quality control, asset management, resource management planning, network control or communications function.

A separate minor non-compliance notice may be issued for every month the Management Performance Measure remains in non-compliance.




• Closed out – when the Contractor’s compliance monitoring system and any audits performed by the Superintendent indicate that the Management Performance Measure is met.

b) Failure to meet Key Performance Measures

• Issued – when the Contractor has failed to meet a Key Performance Measure by a margin less than that listed in Table 5.4.1. A minor non-compliance Notice may be issued in respect of a Key Performance Measure for which a major non-compliance Notice is already open.

Separate minor non-compliance notices may be issued for every Contract Standard not met in each sub-network and for each year of non-compliance.

• Closed out – when the Contractor has demonstrated to the satisfaction of the Superintendent that the Key Performance Measure has been met.

c) Failure to meet Operational Performance Measures

• Issued – when the Superintendent determines, by inspection of the Assets, that the Contractor has failed to comply with a Contract Standard or Response Time of an Operational Performance Measure.

In the event of continuous non-compliance with respect to a Contract Standard, a separate minor non-compliance notice relating to a particular Operational Performance Measure may be issued every two months the same Operational Performance Measure remains non-compliant.

In the event of continuous non-compliance with respect to a Response Time, a separate minor non-compliance notice relating to a particular Operational Performance Measure may be issued each time the Response Time is again exceeded prior to a particular Defect being rectified.

• Closed out – when the Contractor’s compliance monitoring system and any inspections performed by the Superintendent indicate that the Contractor has complied with the Operational Performance Measure for a continuous period of six months.

d) Failure to rectify system failure

• Issued – when the Superintendent determines, by inspection of the Contractor’s compliance monitoring system that systematic corrective action has not been implemented to rectify self-determined recurring non-compliance with the Performance Criteria.




A separate minor non-compliance notice may be issued for every two months the systematic failure is not rectified.

• Closed out – when the Contractor has rectified the systematic failure.
