Refer Appendix (State Highways) 2.1.1.

2.1.2 Objectives

The performance framework will support achievement of the aspirations and goals of the

contract in the following Key Result Areas:

• Safety

• Customer

• Assurance and Value

• Network Performance

2.1.3 Levels of Reporting

There are two main levels of reporting. This is designed so that each team member‟s role,

at each level will have maximum effect on the areas they are accountable for.

2.1.5 Key Performance Indicators

The tables presented in Appendix (WBoPDC Local Roads) 2.1.8 indicate the Key

Performance Iindicators and measures aligned to each of the four KRAs, and the

weighting of each. The weightings may change if the Principal determines that other

business priorities need a higher level of focus.

Each KPI and its associated KPI measure will be scored in one of the performance bands

indicated in Appendix (WBoPDC Local Roads) Table 2.13.

2.1.6 Scoring

Each KRA is broken down into one or more KPIs, which are specifically assigned to one

KRA only; the KPIs are used to determine a KRA score.

Each KRA is made up of one or more KPI measures that demonstrate the Contractor‟s

level of performance achievement for that specific KPI. The measures will be evaluated

against condition criteria such as Network data, asset condition measures, customer

responses or stakeholder survey results. The Contractor must develop a mechanism for

recording and reporting their achievement against each stated measure that can withstand

Principal or independent scrutiny.

Each KPI will be one of the following:

• Aggregation of a number of measures that then add up to a clear quantitative range to

categorise the performance level

• Individual KPI measure that has a clear quantitative range to categorise the

performance level

Once a KPI performance level has been derived, it is assigned a normalised score as

detailed in Table 2.1.3.

Each individual KPI can have a different weight assigned in relation to other KPIs within

a specific KRA, depending on its importance or focus.



Page 7 of 157

2 A KRA score is derived from the individual KPI normalised score and then the sum of all

the KPIs for that KRA is averaged.

The assigned performance level for a KRA will be based on where the resulting KRA

score falls within the score range stated in the Measure Scoring Table 2.1.3. Once a KRA

performance level has been identified, it will then be assigned the normalised score.

Reporting to the CB should detail the KRA performance level, the KRA normalised score

and corresponding KPI normalised scores.

Once a year, an annual overall performance KRA score for the contract is to be developed.

The outcome of the overall performance KRA score will confirm what level of entitlement

and reward the Contractor has earned for the year, as stated in the Measure Scoring Table

2.1.3. Note the Contractor can earn both additional tenure and financial reward; however,

the additional tenure is limited to a maximum term as set out in the Conditions of

Contract.

Each individual KRA can have a different weight assigned in relation to other KRAs

depending on its importance or focus.

The annual overall performance KRA score is derived from the weighted sum of all the

KRA results for the year.

The annual overall performance KRA score is categorised according to the score range in

Table 2.1.3 and assigned a performance level. It is this final performance level which will

confirm the level of entitlement and reward the Contractor has earned.

There are four overriding exceptions to the scoring system outlined above:

• If the performance level is Poor for any KPI measure relating to pavement condition

in three or more consecutive years, the annual overall performance KRA score shall

be Poor

• If the performance level is Poor for three or more KPI measures in any one year, the

annual overall performance KRA score shall be Poor

• If the Contractor fails to collect the data required to report KPM or OPM compliance,

the annual overall performance KRA score shall be Poor

• If the Contractor fails to deliver a KPM Compliance Report, or demonstrates a pattern

of failure to produce monthly OPM compliance reports, the annual overall

performance KRA score shall be Poor

An example of a KRA calculation score is represented in Appendix (WBoPDC Local

Roads) 2.1.10.

The Principal and Contractor may provide additional information in their CB performance

report on extenuating circumstances which may have affected the Contractor‟s ability to

achieve a higher performance level. Additional information in no way allows the

performance level to be changed.

The Contractor and Engineer‟s Representative will work together to develop a

specification for each KPI that indicates:

• What is being measured, how and when it is measured, and by whom

• The performance targets for each individual measure and the measurement band it

relates to: Poor, Minimum Condition of Satisfaction, Best Practice and Outstanding

• The business rules for the provision of the KPI information

• The data sets, data specifications, data calculation and data delivery for each measure

• The supporting information the Contractor must provide and retain on record to

support the KPI score given

Table 2.1.4: Performance Levels and Descriptions

Level of Performance Description of Performance

Poor Significant performance failures and serious gaps in service delivery

Minimum condition of satisfaction An adequate standard of performance with improvement required

Best practice Results reflecting consistent performance achievement underpinned by constructive behaviours that enhance the relationship and deliver innovative solutions for both parties

Outstanding The Contractor is exceeding the Principal’s expectation of performance and has consistently delivered results at a level not previously achieved by suppliers.



Page 9 of 157

2 2.1.7 Performance Evaluation and Monitoring

The results obtained from the monitoring of the KPIs and KRAs will be evaluated to:

• Measure performance and ascertain a score for each KPI for the year under

consideration, in accordance with the performance framework guidelines

• Identify the reasons for poor performance and jointly learn from them

• Create an environment where the behaviours and results associated with poor

performance are considered unacceptable by both the Contractor and the Principal

• Address the potential likelihood of future poor performance and reaffirm the

Principal‟s expectations of performance

• Determine the contract tenure and financial impact outcomes annually

Performance will be measured by each of the operational tiers as specified in the reporting

intervals in Appendix (WBoPDC Local Roads) Table 2.11. It is expected that there will be

a grace period (between three to six months dependent on contract commencement date)

from the time of contract commencement so that the Contractor can complete the

implementation of the system that scores Contractor performance. This will enable the

Principal and the Contractor to ensure there are systems and processes in place that

support the collection and verification of the data and information required for effective

evaluation of performance.

It is expected that the Principal and Contractor will work collaboratively to fully

implement the system in the allocated time frame.

Each KPI within a given KRA will be formally reported in the CB annual report. The

format of the report will be developed jointly between the Contractor and the Principal to

ensure visibility to all, and to enable the provision of clear assessment of performance

over the Contract Period.

2 2.1.9 Safety Triangle

The safety triangle is a combination of several of the safety elements measures to give an

overall score. It has both positive and negative elements combined. The aggregated safety

triangle formula represents the safety score. Within the overall score is the opportunity to

recognise positive performance as represented in the triangle and an incentive to minimise

negative performance.

Total Recordable Injuries (TRI)

Total Recordable Injury includes Serious Harm Injury, Lost Time Injury, Medical

Treatment Injury and employees on restricted work duties. It excludes First Aid Injury.

The Contractor maintains records of all TRIs for each year. For the year measured, the

score is calculated based on the number of TRIs reported multiplied by (-20) to give the

overall TRI score for that year.

Safety non-compliances

The Contractor maintains records of all safety non-compliances for each year. For the year

measured, the score is calculated based on the number of safety non-compliances reported

multiplied by (-10) to give the overall safety non-compliance score for that year.

Close out of Safety non-compliances

The Contractor maintains records of all safety non-compliances closed out for each year

and the number of safety non-compliances still open. For the year measured, the score is

calculated based on the number of safety non-compliances closed out multiplied by (+20)

plus the number of safety non-compliances still open multiplied by (+0.5) to give the

overall safety non-compliance close-out score for that year.

2 Safety training, workshops, presentations

The Contractor maintains records of all safety training, workshops, and presentations for

each year multiplied by the number of FTEs attended. For the year measured, the score is

calculated based on the number of safety training, workshops, and presentations multiplied

by FTE attendance multiplied by (+1) to give the overall safety training, workshops, and

presentations score for that year.

Near-miss reporting

The Contractor maintains records of all near-miss reports for each year multiplied by the

number of different FTEs who provided near misses. For the year measured the score is

calculated based on the number of near misses reported multiplied by number of different

FTEs who provided near-miss reports multiplied by (+0.5) to give the overall near-miss

report score for that year.



Page 18 of 157

2 2.1.10 Example Calculation of KRA Score

There are 4 Key Result Areas (KRAs). Each KRA is evaluated annually. The annual

overall performance level determines the contract‟s outcome, for example additional

tenure and financial reward.

KPI

Each Key Performance Indicator (KPI) can have more than one measure. Each measure

has a different weighting. The KPI performance level is dependent on the relevant KPI

measures performance levels. In this example, KPI 1 has three relevant measures

(Measure 1, Measure 2 and Measure 3). The KPI measure performance level has been pre-

determined for this example.

Weighting Performance Level Normalised Score

2 2.2 OPM Monthly Evaluation Example

Part A: Establishing the At-Risk Payment Value for the Contract Period

Monthly At-Risk Payment

Tendered lump sum for Schedule Item 1

$109.2M

Annual tendered lump sum for Schedule Item 1

$109.2M / 7 years = $15.6M

Monthly tendered lump sum for Schedule Item 1

(1/12) * $15.6M =$1.3M

Maximum monthly at-risk payment

$109.2M / 2,500

= $43,680

For further information on payment, see Basis of Payment (WBoPDC Local Roads),

Section 1.

The value of the monthly at-risk payment is vulnerable to change dependent on the level

of non-conformance.

Part B: Monthly Network Compliance Evaluation

Occurrences

The OPM non-compliances for the full Network length are summarised. All these OPMs

evaluate non-compliant response times for a calendar month.

Page 22 of 157

2 In this example the MNCS is less than 7; therefore no financial penalty is imposed

assuming an equivalent high level of performance on the State Highway network. If the

MNCS was between 7 and 25 a variable financial penalty would result assuming an

equivalent level of performance on the State Highway OPM evaluation. If MNCS was

over 25, or if the %Non-Compliance for any OPM Category was over 35%, then 100%

financial penalty would be imposed.

If the overall monthly score was 21

The following equation determines the proportion of payment that is adjusted, where x =

21, which is the MNCS:

Proportion adjustment = −0.2865x2 + 3.804x + 87.414

Proportion adjustment (%) = 100 − (−0.2865 21 2 + 3.804 21 + 87.414)

= 100 − ( −126.3 + 79.9 + 87.414)

= 59.0

Maximum monthly at-risk payment: $43,680

Proportion adjustment: 59.0%

Monthly at-risk payment post-

adjustment:

$43,680 * 59.0%

= $25,771

Payment for month post-adjustment: = $(1,300,000-25,771)

width determined in accordance with Table 3.2.3. The objective of the additional width is

to take into account environment factors associated with the Carriageway Section

including terrain, width, and road group and speed zone. The repair is to be completed at

grade with the existing seal.

For the derivation of the additional width the terrain type, existing width, road group and

speed zone are taken from the RAMM carriageway table current at the time of the

underslip. The number of metres underwidth are determined as the difference between the

required width, determined in accordance with the WBoPDC Development Code, and the

existing width.

The additional repair width is determined as the maximum width from Table 3.2.2 from

the four environmental factors.

The following example is provided for the avoidance of doubt. Where an underslip has

occurred at a road segment categorised as:

Mountainous terrain

0.5m underwidth

Road group 4

80km/hr speed zone

From Table 3.2.2, the additional width is determined as 0.5m required as a result of the

mountainous terrain being greater than the 0m required for the 0.5m underwidth, the 0.3m

for the road group 4 and the 0.3m for the 80km/hr speed zone. The total repair width

required from the outside edge of the original seal or carriageway (prior to the slip) is

therefore the minimum 0.3m plus the additional 0.5m (total 0.8m).

The Principal has implemented pavement deterioration modelling to supplement treatment

intelligence currently limited to the RAMM Treatment Selection Algorithm and data

analysis, as detailed in the NZTA State Highway Asset Management Manual. It is

expected that the outputs of these models will form a significant input into the

development of the Forward Work Programme.

In order to achieve the above outputs, the Contractor is required to:

Purchase and maintain the appropriate New Zealand dTIMS software license through

Infrastructure Decision Support (IDS)

Agree the modelling procedure with the Principal on an annual basis prior to the

commencement of the annual planning cycle

Implement the latest IDS NZ dTIMs CT template and calibrate this for local

conditions prior to the first modelling run

Recalibrate the model annually following each Forward Works Programme cycle

Reporting Requirements

Input Parameters

Comments are required on any significant changes made to the default input parameters.

Outputs

Outputs from the predictive modelling should include:

Forecasting of maintenance needs; and

Prediction of future Network condition

Utilisation of Outputs



Page 39 of 157

4 Interpretation and/or explanation must support all graphical outputs and should highlight:

The message illustrated with the figure (e.g. the roughness prediction suggests that the

current maintenance effort will maintain the current roughness across the Network);

Whether the graph supports actual expectations of the Network performance in the

opinion of the Contractor‟s expert asset managers.

Commercial Interest

Similar to the recording of maintenance cost in RAMM, actual unit cost rates to the

Contractor do not have to be used in the dTIMS modelling process. For this purpose the

Contractor is allowed to use typical unit rates expected of such a Network, which

realistically reflect cost differences between treatment types. The Principal is only

interested in global quantities of work and the impact of maintenance on the future

condition.

4.1.10 KPM Compliance Reports

The Contractor shall supply an annual KPM Compliance Report. The report shall

compare actual performance against relevant Contract Standards in both tabular and

graphical form using the most recent condition data gathered in the year of the report.

4.2.4 Environmental Protection Plan

The purpose of the Environmental Protection Plan (EPP) is to foster an environmentally

responsible attitude on the part of the Contractor and its subcontractors and employees,

and to ensure compliance with relevant environmental protection laws and especially the

Resource Management Act 1991.

Because of the nature of the Services, the Contractor may from time to time be exposed to

environmentally sensitive situations which could involve contamination of air, soil, and/or

water systems. Situations will arise when there is a need to use appropriate environmental

protection measures. In these cases, the provisions of the Resource Management Act 1991

and other similar Acts or Regulations must be strictly observed. The Contractor needs to

be aware of environmental laws and regulations and to understand the requirements

therein.

In undertaking work which involves environmental risks, emphasis should be on the

fundamentals such as how to avoid offences of:

Air and water pollution (by screening, filtering, channelling and washing at approved

sites)

Unlawful hazardous waste disposal, by containment, storage and dumping by

approved methods at approved sites

Chemical spills (by appropriate maintenance of suitable equipment)

Contamination (by cleaning equipment at an approved site after each job)

The EPP must:

a) Identify all obligations with respect to environmental matters in accordance with the

BoPRC and legislative requirements

b) Detail systems, work practices and actions to manage environmental outcomes

c) Identify the hazards to which the environment may be exposed in the process of

carrying out work

The requirement for the Contractor to locate the presence of any horticultural or

other susceptible crops within the vicinity of the work site.

iii) Sediment and stormwater control

iv) Noise control

v) Pest control

vi) Control of application of herbicides

vii) Storage of hazardous substances

viii) Refuelling of plant

The EPP must ensure reporting and recording of environmental incidents. It is a

requirement of this Contract that any such incident be advised promptly to the Engineer‟s

Representative.

The Delivery Time for the initial EPP shall be prior to commencement of Services and for

reviews, as required by the plan.

Resource consents held in respect of the Services are identified in Appendix (WBoPDC

Local Roads) 3.6

4 4.2.5 Customer Care Plan

Introduction

The following is a summary of the way we do things at WBoPBC.

WBoPDC‟s Customer Focus Approach aims to provide an environment where:

Customer needs are understood

Information is accurate and user-friendly

Advice and services are provided in a timely and professional manner

WBoPDC‟s customers and communities do not necessarily make a distinction between

service provided by a contractor or service provider, and services provided directly by

WBoPDC. Consequently customer care and service provided through a contractor or

service provider should display the same values and care that WBoPDC would provide.

How we do it

The customer is our first and most important priority at WBoPDC. We try very hard to

provide outstanding customer service every time. This is done by meeting clearly stated

customer service performance levels that encourage us to:

Be easy to contact

Listen and learn from customers

Work with customers to find solutions

Explain our decisions

Respond and update customers accurately and promptly

Give consistent and reliable service

Keep our promises

Learn from our mistakes

Continuously improve our services

Be friendly and professional

What will the Contractor need to know and do, to meet our Customer Focus

requirements?

Have knowledge of and a commitment to, our Customer Focus Charter

http://www.westernbay.govt.nz/Documents/CustomerFocusCharter.pdf. Be prepared

to participate in Customer Focus training where appropriate

Be supportive of actions required to be taken to improve processes (by WBoPDC), as

a result of customer feedback

http://www.westernbay.govt.nz/Documents/CustomerFocusCharter.pdf



Page 45 of 157

4 As an agent of WBoPDC we expect the Contractor to provide a similar level of customer

service. It is essential that the community can rely on consistent performance from

WBoPDC and anyone acting on our behalf.

Customer Care Plan (CCP) The CCP will as a minimum address the following issues:

External Customer Care Strategy

1. Identification of external customers and their interface with WBoPDC on roading

issues

2. Use of technology to facilitate communication between the customer, Contractor and

WBoPDC on roading issues

3. Integration of WBoPDC‟s service request system in order to provide a seamless

Page 54 of 157

4 4.5 Treatment Design

Pavement design and geometric design standards for pavement renewals (strengthening),

seal extensions, seal widening, and any other new pavement works (e.g. intersection

improvement) shall be undertaken in accordance with the latest Austroads Guide to

Pavement Technology: Parts 2 and 5 together with the N.Z. Supplements to the Austroads

Guides, and the WBoPDC Development Code. Design life is to be 25 years.

4.5.1 Pavement Treatment

A specific design and technical specification shall be produced by the Contractor prior to;

The construction of any seal extension, seal widening, or other capital works

Any maintenance activity or treatment that changes the RAMM carriageway width at

year 0 by more than 300mm on either side of the road

Any pavement Rehabilitation in excess of 100m length

4.5.2 Geometric Standards

Prior to undertaking Rehabilitation works, the Contractor shall identify and seek an

instruction from the Engineer‟s Representative to perform the following and any other

asset improvements:

a) Camber correction above 2

b) Provision of super-elevation from a camber cross-section

c) Overlay above 200mm depth extra to the design overlay thickness to correct shape in

the longitudinal direction

d) Seal widening

e) Flattening of shoulder, berm and side slopes

Consequential works arising from any aspect of Rehabilitation that are not defined as part

of the Services are also to become part of the Services. Consequential works include, but

are not limited to:

a) Earthworks

b) Drain recutting, and consequential scour protection

c) Raising or lowering of service covers, kerbs, sight rails and guardrails

d) Culvert extensions

e) Construction or extension of retaining walls

The Contractor shall take care to ensure that shoulder, berm and side slopes within the

clear zone are not made steeper by the Rehabilitation treatment, and that the width of such

slopes that can safely be traversed by errant vehicles is not reduced.



Page 55 of 157

4 4.5.3 Construction Requirements

Rehabilitation shall not result in more than 1000m of traffic lane (having been sealed prior

to the Rehabilitation works) remaining unsealed for a period exceeding four weeks at any

single project site, unless specific approval has been provided by the Engineer‟s

Representative; such approval shall not be unreasonably withheld.

The Contractor shall ensure, through attention to design and construction methodology,

that:

a) Pavement works do not unravel and that detritus and loose or surplus material does

not create a traffic hazard

b) There is no flushing, bleeding, scabbing or stripping and that binder is not picked up

on any tyres. There must be no accidents associated with surfacing performance

c) In urban areas, detritus and loose or surplus material shall not be tracked into

adjoining properties and businesses.

All pavement markings and raised pavement markers shall be reinstated after completing

resurfacing or Rehabilitation work within one week, and before the removal of temporary

traffic control.

Worksites that affect property frontages must be left in the same or better condition and

berms that are mowable must be reseeded to provide a result that matches the pre-existing

condition. Rural berms must provide for safe cutting of shelter belts where reasonably

possible. Access should be reinstated on a like for like basis. The Contractor needs to

take sufficient photographs before and after construction to demonstrate compliance with

this requirement.

4.5.4 Quality Assurance and Post Construction Demonstration of Pavement Design Life Achievement

The minimum design life of any Rehabilitation (strengthening) carried out by the

Contractor shall be 25 years, unless stipulated otherwise by the Engineer‟s Representative

in writing.

For short pavement repairs having a total length less than 100m, the minimum design life

shall equal or exceed the remaining life of the adjoining pavement.

In order to provide the Principal with assurance that the required design life for both

pavement renewals and new pavements is likely to be achieved the following quality

assurance process is to be followed.

Design Report At least 2 months for capital works including seal extension, seal widening and minor

improvements, and at least 1 month prior to the programmed start date for

renewal/Rehabilitations, a detailed design, and a design report shall be provided to the

Principal which incorporates:



Page 56 of 157

4 The geometric design standards previously approved by the Principal. This may or

may not comply with the current Austroads Guide to Road Design Part 3: Geometric

Design depending on site constraints, and funding provisions, and value for money

considerations

The design report is to document the investigations, predicted failure mechanism, and

is to include a quality plan setting out sampling and testing requirements, and critical

hold points

Risks are to be identified and mitigation measures presented

Communications with adjacent residents, Iwi, road users, and emergency services are

to be noted and taken into account in the design

The Contractor‟s Physical Works Manager is to be responsible for ensuring that all

the quality assurance requirements have been met

A road safety audit waiver (NZTA May 2013 Road Safety Audit Exemption Form)

completed for the Principal acceptance.

Pavement Rehabilitation/New Pavement - Construction Completion Report Within 2 months of the construction of the 1

st coat seal, the Contractor shall supply to the

Principal a Construction Completion Report for each Site which shall include, as a

minimum, the following:

Key original design assumptions

The renewal/new pavement quality plan

Evidence of construction compliance with key original design assumptions as well as

any deviation from the design

All quality assurance results

All compliance results (e.g. NZTA B/2 shape)

Photographs of the Site during treatment and on completion;

Customer engagement, issues , technical or construction challenges and any ongoing

commitments

As-built extracts from RAMM

New Pavement / Pavement Rehabilitation Post Construction Design Assessment

Post-construction design assessment will be used as the tool for verification of value

assurance.

Between 10 and 15 months after construction, the Principal will have undertaken high-

speed data surveys over road groups 1 to 3 and less frequently for other roads groups as

outlined in Appendix (WBoPDC Local Roads) Table 5.1.



Page 57 of 157

4 Within 2 months of receipt of this data, and in conjunction with other Contractor-sourced

inputs, the Contractor shall assess the success of the renewal/new work outcomes and

supply to the Principal a Post-Construction Design Assessment Report. The report shall

include:

Construction Completion Report

Photographs of areas of concern

Roughness condition, see below

Rutting condition, see below

Shape condition, see below.

The Principal is seeking confirmation and assurance of the original treatment selection and

design through the evaluation of the above inputs, including cross-verification of outputs

and conclusions from these multiple data sources.

Annually thereafter, by 30th

June, the latest source information on roughness, rutting and

shape condition, for each project, shall be provided by the Contractor to the Principal. The

information will ideally be presented in a spreadsheet showing all of the projects involving

pavement renewals and new pavement undertaken under the contract for the duration of

the Contract. This information shall form a critical component for ongoing design

consideration in developing future optimal design solutions.

The post-construction design assessment period will be the lesser of:

5 years from the date of the first coat seal or

Contract Period left to run at the time of the first coat seal plus any additional tenure

reward

Roughness

Roughness will be assessed annually throughout the assessment period based on the

Principal‟s annual HSD survey. Assessment for compliance with the roughness criteria

shall be in terms of the 100m moving average NAASRA. The 100m moving average shall

be calculated from the HSD roughness measurements recorded at 20m intervals in each

lane.

The extent of survey shall include an additional 40m at each end of the treatment Site.

The progression in annual roughness shall be monitored and compared with the Principal‟s

expectation that roughness on new works should not exceed 75 NAASRA in the first 5

years following date of 1st coat seal, and 65 NAASA for asphalt.

Where more than 50% of the calculated moving averages exceed these values, the

Principal may conclude that the work is unlikely to achieve its design life and cannot be

counted as contributing towards meeting of the Contractor‟s nominated quantity

obligations.



Page 58 of 157

4 Rutting

Rutting will be assessed annually throughout the assessment period based on the

Principal‟s annual HSD survey of road groups 1 to 3 and less frequently for other roads

groups as outlined in Appendix (WBoPDC Local Roads) Table 5.1.

Assessment for compliance with the rutting criteria shall be in terms of the 20m mean rut

depth by wheel path.

For each wheel path the characteristic rut value shall be determined as follows:

Rx = ϻx +K □x

Where: Rx = Characteristic rut value for wheel path (e.g. RLWP or RRWP) x (mm)

ϻx = Mean of the 20m wheel path means for wheel path x

K = 1.28

□x = Standard deviation of the 20m wheel path means for wheel path x

x = Either left wheel path (LWP) or the right wheel path (RWP)

Note that the above assessment is based on wheel paths by site not by lane.

The rutting progression shall be assessed annually for projects within road groups 1 to 3,

and at the interval that HSD is collected for projects within the remaining road groups.

Where after 3 years following the first coat seal, the characteristic rut value of any

pavement construction or rehabilitation project exceeds 15mm in any wheel path and is

continuing to increase, the Principal will conclude that the work is unlikely to achieve its

required design life, and that unless major rework approved by the Principal is undertaken,

that particular project cannot be counted as contributing towards provision of the

nominated preservation quantity or the capital work programme.

Surface Shape and Condition

The surface shape requirements outlined in this clause shall be complied with throughout

the pavement assessment period.

Surface shape shall be measured with a straight edge and wedge. Using the methodology

set out in NZTA B/2, NZTA B/5, NZTA M/10 and NZTA P/11 depending on the

pavement type and layer. Surface shape measurements will be performed at transverse

construction joints, service covers and in any other area where the Principal considers the

limits may have been exceeded.

The surface shall meet the requirements of (or as agreed with the Principal):

a) NZTA B/2 for unbound granular pavements with chip seal

b) NZTA B/5 for modified pavements with chip seal

c) NZTA M/10 for Dense Graded Asphalt and Stone Mastic Asphalt layers

d) NZTA P/11 for OGPA layers



Page 59 of 157

4 In addition, the surface shape shall be such that there is no visible cracking or ravelling (or

fretting) within three years of the second coat seal or AC surface.

If any of the annual assessments of roughness, rutting or shape fail to achieve these

criteria, the Contractor shall agree with the Principal an appropriate repair methodology in

order to achieve compliance.

4.5.5 Carriageway Lighting

General Design Principles As a minimum, new and replacement carriageway lighting design must comply with the

requirements of AS/NZS 1158: 1999.

The design of street lighting must also meet the requirements of AS/NZS 1158.3.1: 1999

clause 2.3.3.4 in relation to “Light spilled onto abutting properties”.

Exemptions A large proportion of the existing lighting inventory have been designed in accordance

with the minor road provisions of NZS 6701 that has been superseded by AS/NZS 1158.

There are also a number of subdivisions that have decorative type fixtures. The

replacement of lighting fixtures, brackets, poles or decorative fixtures for the sole purpose

of meeting the AS/NZS1158 standard is not within the scope of the Contract.

In subdivisions, where the use of different installation types would compromise aesthetic

consistency, the Contractor shall make every effort to retain and procure installations

consistent with those existing. This may involve replacement of badly corroded or

discoloured components, minor modifications, painting or strengthening as appropriate.

The Contractor may replace decorative lights with agreed alternative AS/NZS 1158.3.1

category P3 or P4 compliant lighting after consultation with all local residents, including

residents adjacent to the adjacent carriageways 100m beyond the last light to be upgraded

and the Engineer‟s Representative. In such cases residents and the Engineer‟s

Representative shall be given full details of the proposed new installation, including

drawings of the lighting installation and plans of the proposed location of each installation.

The notification shall include the name and contact details of the Contractor‟s

Representative.

The demarcation points between types of lighting installation shall be at appropriate

locations, for example intersections, limit of residential area, or edge of reserve.

Power Network Company Undergrounding In the event of under grounding of any particular area, the ownership of reticulation poles

supporting street light installations will transfer to the Principal when the main power lines

are removed. At that time the condition rating of the lighting installations may change as a

result of the condition of the poles. As soon as notification of an under grounding project

is received, arrangements shall be made with the Engineer‟s Represnetative for the pole

condition to be surveyed.



Page 60 of 157

4 The CB may consider a recommendation to the Principal for additional funding for the

new cabling, renewals and capital works involved with replacing the light installations.

Previous condition ratings with the poles excluded will be consulted and where

replacement of brackets and/or luminaires could be expected under the Contract, the CB

will negotiate an appropriate reduction to the Contract Price.

Page 62 of 157

4 4.7 Network Control

In performing all network control activities the Contractor is expected to take ownership

of responses and managing customers‟ reasonable expectations within the bounds of

policies. The Principal is to be consulted where there may be uncertainty in terms of

policy and must be informed immediately of issues likely to be escalated to elected

members or be taken to the media. The Contractor will remain responsible for issues that

may arise unless the Principal advises the Contractor in writing that the Principal has taken

4.7.2 Land Acquisition

Where acquisition of land for roading purposes is necessary to enable the Contractor to

carry out the Services, the Contractor shall initiate and administer the land acquisition

process and recommend compensation in accordance with the WBoPDC procedures

detailed below.

The Delivery Time for the survey plan of the land required for road to be delivered to the

WBoPDC Legal Property Officer shall be 2 months following completion of the physical

works for which land acquisition was required.

The WBoPDC procedure for acquisition of land for roading purposes is as follows:

1. The Contractor shall provide preliminary drawings to the landowner/occupier and the

WBoPDC Legal Property Officer indicating the area required for construction

purposes.

2. The Contractor shall calculate the amount of compensation on a per square metre

basis being offered by WBoPDC for the land required for construction purposes and

advise the WBoPDC Legal Property Officer of the proposed compensation. Once

WBoPDC has approved the compensation the Contractor will advise the

landowner/occupier, and advise them also of the alternatives available if the amount is

not acceptable.

3. The Contractor shall obtain a signed land entry agreement to enter from the

landowner/occupier prior to finalising the design and proceeding with construction.

Once the construction has been completed the Contractor will notify the WBoPDC

Legal Property Officer who will arrange for the works to be surveyed.

4. The WBoPDC Legal Property Officer will on receipt of the approved survey plan

write to all landowners providing a copy of the plan with the final land area required

along with the amount of compensation assessed. At this point landowners will need

to indicate whether they are registered for GST and whether there are any outstanding

issues relating to the construction.

5. The WBoPDC Legal Property Officer will then obtain WBoPDC‟s formal consent to

the acquisition of the land.

6. An agreement to acquire the land will be then sent to landowners for their perusal and

signatures. Landowners are to return the signed document along with an invoice to

WBoPDC for the compensation payable for the land.

7. On receipt of the agreement, WBoPDC will execute the document and subject to

Compensation Certificate being registered against the landowners title will then pay

the compensation to the landowners.



Page 64 of 157

4 8. Once the agreement has been lodged with LINZ, WBoPDC will undertake to

discharge the Compensation Certificate off the landowners‟ title.

9. In the case of multiple owned land where WBoPDC may have to become involved at

an early stage in the complex communication and protracted negotiation commonly

required when dealing with these situations, the Contractor is required to put in a

similar input as would be needed for purchase of land from any cautious, reluctant

landowner and WBoPDC would then provide the rest of the input required.

IMPORTANT NOTE: The Contractor shall advise the owner/occupier that, should at

any time during this process the landowner/occupier seek to on sell all or part of their

land, they must inform the WBoPDC Legal Property Officer of their intent and ensure a

clause is placed in their agreement for sale and purchase that the area to vest in WBoPDC

as road is excluded from the sale.

The WBoPDC procedure for negotiation of compensation follows. Under no

circumstances shall the Contractor offer or provide any form of compensation or payment

whether monetary or otherwise which has the intention or effect of inducing

landowners/occupiers to sign land entry consents other than compensation duly payable in

strict accordance with the procedure below:

1. The Contractor will obtain from the WBoPDC Legal Property Officer all necessary

valuation and GIS information held by WBoPDC, including a calculation of either

100% or 150% of property‟s unimproved land value on a per square metre basis – see

WBoPDC Policy Compensation for Land Acquired for Road.

2. Subject to WBoPDC approval, the Contractor is to supply landowners/occupiers with

an offer of compensation at either 100% or 150% of the unimproved land value per

square metre for the proposed land take area plus GST where the landowner is

registered for GST in respect of land, and subject to final survey.

3. The Contractor will supply to the landowner/occupier the above process summary,

laying out the process for the acquisition and the involvement of the Contractor and

WBoPDC in the process.

4. Should the landowner/occupier accept the above offer of compensation, the

calculation of the amount of compensation per square metre shall be included in the

land entry consent and a copy of the consent provided to the WBoPDC.

5. Should the landowner/occupier not accept the above offer of compensation, the matter

will be referred to the WBoPDC Legal Property Officer.

1. Poles

2. Brackets

3. Lanterns



where:


the three components for each carriageway light, in accordance with the following

documents, during each required structural inspection:

a) WBoPDC Street Lighting Rating Standards and Definitions

Note: Where a reticulation pole owned by the lines network company is used, then the

condition of the pole is not taken into consideration. However the bracket condition

assessment must include the integrity of the fixings to the reticulation pole. Hence if the

pole is in a condition that there is any danger of the bracket falling off the pole, then it

must be rated 5. Responsibility for assessing the strength of a wooden pole rests with the

network company, and any concerns regarding poles should be passed on to them in

writing.

5 5.19 Footpaths

5.19.1 Length for Renewal

The footpath length for renewal is determined directly from the Footpath Deficiency

Rating Survey completed in accordance with Appendix (WBoPDC Local Roads) 5.3.4.

The Length for Renewal KPM in each community is calculated using the following

formula:

𝐿𝑒𝑛𝑔𝑡𝑕 𝑓𝑜𝑟 𝑅𝑒𝑛𝑒𝑤𝑎𝑙 = 𝐿𝑒𝑛𝑔𝑡𝑕 𝑡𝑜 𝑏𝑒 𝑅𝑒𝑝𝑙𝑎𝑐𝑒𝑑

recorded against it, and only this length. Where a footpath section has no faults the

Length to be Replaced is 0m.



Page 128 of 157

5 5.20 Safety Performance Index

The Principal will provide Field Input sheets that identify deficiency items to be recorded.

The field inspection procedure is:

1. Each section of road is based on lengths between junctions, surface changes or width

changes and hence each section varies in length. The Field Input sheets can record up

to 1500m. For sections longer than 1500m, several Field Input sheets will be required.

2. Each road section is considered in 300m portions. Each portion of 300m is driven

over slowly in each direction so that the information can be observed as required.

When the section is complete the entire length is driven at normal speed to record the

speed environment and sight distance deficiencies.

3. After inspection of a 300m length is complete, the Field Input sheets are marked with

the number of deficiencies or a percentage of the 300m length as indicated.

4. Intersection deficiencies relate to the approach leg only. Flag lighting deficiencies

apply when dealing with the main road (i.e. head of the tee section) and must only be

recorded once.

5. Some items relate to both directions (such as centreline markings) whilst others deal

with one side of the road only.

The collected information is entered into the Safety Performance Index model to be

provided by the Principal in the format of an electronic spreadsheet.

The model will produce the Safety Performance Index for each road section by:

Converting the individual row deficiencies to a rating between 0 (good) and 5 (bad)

based on the portion of deficient length

Calculating the road section Safety Performance Index using a weighted mean of the

individual row deficiency rating coupled with other influencing factors.

5 5.21 Accidents

The NZTA publication on which this KPM is based also publishes, and is linked to the

„crash reporting rate‟ for the Western Bay of Plenty district, which is based on several

factors such as hospital accident rates. To avoid any penalty to the Contractor for

improving the reporting rate, this measure will be standardised for the reported injury

crashes, through an agreed standard statistical technique.

5.21.1 Percent with Road Related Factors

The Percent with Road Related Factors KPM is calculated using the following formula:

𝑃𝑒𝑟𝑐𝑒𝑛𝑡 𝑤𝑖𝑡𝑕 𝑅𝑜𝑎𝑑 𝑅𝑒𝑙𝑎𝑡𝑒𝑑 𝐹𝑎𝑐𝑡𝑜𝑟𝑠 =𝑁𝑜. 𝑜𝑓 𝐼𝑛𝑗𝑢𝑟𝑦 𝐶𝑟𝑎𝑠𝑕𝑒𝑠 𝑖𝑛 𝑊𝐵𝑜𝑃 × 𝑁𝑜. 𝑜𝑓 𝑇𝐿𝐴𝑠 𝑖𝑛 𝐺𝑟𝑜𝑢𝑝 𝐷

𝑁𝑜. 𝑜𝑓 𝐼𝑛𝑗𝑢𝑟𝑦 𝐶𝑟𝑎𝑠𝑕𝑒𝑠 𝑖𝑛 𝐺𝑟𝑜𝑢𝑝 𝐷× 100

where:

No. of Injury Crashes in WBoP is determined by creating a crash list in the Crash

Analysis System with the following parameters for Western Bay of Plenty district:

1. Latest complete 5 year period

2. Injury crashes only

3. Rural roads only

4. Local roads only

5. Crashes with Road Factors as a contributing factor

6. Exclude Matakana Island roads

7. Exclude crashes where wet surface or wet weather has been coded as a “Road

Factor”.

No. of Injury Crashes in Group D is determined by creating a crash list in the Crash

Analysis System with the above parameters for peer Group D, which as at December

2004 consisted of the following Territorial Local Authorities:

1. Ashburton

2. Far North

3. Franklin

4. Horowhenua

the above crash list for peer Group D, which as at December 2004 was 21.

The method of analysis is described in the Accident KPM Analysis document to be

provided by the Principal.

5.21.2 Social Cost

The Social Cost KPM is calculated using the following formula:

𝑆𝑜𝑐𝑖𝑎𝑙 𝐶𝑜𝑠𝑡 =𝑆𝑜𝑐𝑖𝑎𝑙 𝐶𝑜𝑠𝑡 𝑜𝑓 𝐼𝑛𝑗𝑢𝑟𝑦 𝐶𝑟𝑎𝑠𝑕𝑒𝑠 𝑖𝑛 𝑊𝐵𝑂𝑃 × 𝑉𝐾𝑇 𝑖𝑛 𝑇𝐿𝐴𝑠 𝑖𝑛 𝐺𝑟𝑜𝑢𝑝 𝐷

5 5.22 Visibility

5.22.1 Length with Inadequate Available Sight Distance

The objective of the Length with Inadequate Sight Distance KPM is to drive an

improvement in forward visibility and thus safety over the network by changing the

roading environment (e.g. sight benches, curve easing, land purchase and/or vegetation

control)

The Length with Inadequate Sight Distance KPM is calculated using the following

formula:

𝐿𝑒𝑛𝑔𝑡𝑕 𝑤𝑖𝑡𝑕 𝐼𝑛𝑎𝑑𝑒𝑞𝑢𝑎𝑡𝑒 𝑆𝑖𝑔𝑕𝑡 𝐷𝑖𝑠𝑡𝑎𝑛𝑐𝑒 = 𝐿𝑒𝑛𝑔𝑡𝑕 𝑤𝑕𝑒𝑟𝑒 𝑆𝑆𝑆𝐷 < 𝐴𝑣𝑎𝑖𝑙𝑎𝑏𝑙𝑒 𝑆𝑖𝑔𝑕𝑡 𝐷𝑖𝑠𝑡𝑎𝑛𝑐𝑒

where:

Safe Sight Stopping Distance (SSSD) is determined for each 250m section using the

Mean Free Speed (as recorded in the RAMM database at 250m intervals for rural

sealed roads) less 10km/hr in accordance with AustRoads Rural Road Design – Guide

to the Geometric Design of Rural Roads (1993), Section 6

Available Sight Distance is determined by measuring the distance between targets

1.15m in height from the road surface continuously along the centre of each lane, as

described in the WBoPDC Group 3 Roads – Available Sight Distance Review –

with the relevant OPMs.



Page 139 of 157

6 6.5 Urban Vegetation Control

Further to Appendix (WBoPDC Local Roads) 6.2, Table 6.2.2, the requirements for

vegetation control in urban areas are detailed below.

6.5.1 Sealed and Paved Areas

The following standards shall be achieved within urban metalled areas, sealed and

concrete areas, vehicle and pedestrian access, pavement and footpath edges and kerbs:

a) Grass shall not encroach more than 100mm onto the paved surface, except isolated

strands of kikuyu may encroach 200mm.

b) All joints and cracks in paved surfaces on roads shall be kept weed free at all times,

including:

The joint between kerb channel and sealed carriageway

The joint between kerb and footpath

Construction joints in footpaths or kerbs

c) The trafficable shoulder on unkerbed roads shall be maintained in a vegetation free

condition.

d) Footpaths, parking areas and hard surfaces in the CBD areas of Te Puke and Katikati

must be vegetation free. Edges around all structures, gardens, footpaths, kerblines

and trees must be maintained and the vegetation shall be trimmed flush with the

edges.

6.5.2 Watertables and Drainage, Culvert Inlets and Outlets

Treatment shall ensure the free flow of water by eliminating rank growth and aquatic

growth in side drains. If any watertable or drain becomes subject to erosion, treatment

shall be modified to minimise instability of the drain.

6.5.3 Roadside Sign Posts, Manholes, Cesspits, Poles, Switchgear Boxes and Transformers

Vegetation around these items (and under structures supported by them) shall be treated

for a clearance of 200mm round each item.

6.5.4 Herbicides and Application of Sprays

Should the Contractor elect to use herbicides for temporary control of vegetation within

recreational reserves, public spaces and along roadsides and drains, the following

standards shall apply:

a) In general, the Contract is restricted to cosmetic spraying, that is spot spraying and

edge spraying using low pressure equipment (less than 3200 kPa or 40 psi). Where

practical, contact weed control should be used.



Page 140 of 157

6 b) Any chemical spraying outside these limits shall be done only by a Registered

Applicator under the Pesticides Act 1979 (and amendments).

c) The Contractor shall not spray more than 100mm behind the edge of kerb, footpath or

pavement.

d) Special care must be exercised to prevent damage to adjoining vegetation through

carrying out operations incorrectly. Damage caused by spray operations must be

reported to the Engineer‟s Representative and shall immediately be made good by the

Contractor at its expense.

e) Special care will be necessary in all landscaped areas and areas adjacent to private

property. Frontages in urban areas that are maintained by private individuals in a neat

and tidy condition shall not be sprayed.

f) In areas which are bounded by grassed or planted batters, any spraying shall be done

in a manner that minimises the risk of creating instability in the batter through loss of

vegetative cover.

g) To reduce the potential for fluvial erosion, herbicides shall not be used on the erodible

volcanic soils bounded within the area east of the Mangorewa River and South of

SH2.

6.5.5 Mowing

Mowing of each area shall conform to one of the following type definitions. The

Contractor shall work within the specified mowing tolerances without causing significant

damage to the ground or reducing grass height to less than 20mm.

Litter including glass shall be removed immediately prior to mowing. Any litter

subsequently shredded as a result of mowing shall be removed by the Contractor.

Type A

The height of grass must be maintained between a minimum height of 20mm and a

maximum height of 75mm. Clippings shall be removed. Grass clippings falling onto

paths, drives and carparks or other such similar areas shall be swept from the surface

before the Contractor leaves the site.

Type B

The height of the grass must be maintained between a minimum height of 20mm and a

maximum height of 75mm. Grass clippings shall lie where they fall except clippings

falling onto paths and drives, roadways and lined surface water channels or other such

similar areas shall be swept from the surface before the Contractor leaves the site.

Type C


maximum height of 75mm.

Type D


maximum height of 75mm. Grass clippings shall lie where they fall.



Page 141 of 157

6 In general, this relates to street berms. Typically these areas are being mown 20-30 times

per year.

Type E


maximum height of 200mm. The Contractor shall use equipment from which grass is

spread evenly over the cut surface, without windrows.

In general this applies to more remote street berms.

Type F


maximum height of 400mm.

In general this applies to large areas of unused reserves where a lesser standard of control

than Type E is required. Typically these areas are mown 1-5 times a year with a flail or

slasher type mower.

Type G Scrub Cutting

The Contractor‟s responsibility is limited to the cutting of light scrub growth and branches

of a nominal trunk diameter of less than 75mm located within the legal road reserve. Any

treatment which is required beyond the scope of this section because of location or size

shall be reported to the Engineer‟s Representative for further investigation.

On completion of a scrub cutting the following clearances shall have been provided:

a) Clear in a horizontal line 5.0m from the left edge of the carriageway for a height of

4.5m

b) Clear of the surface water channel

c) Clear to within 200mm of the bank, where the bank is within 3.0m of the carriageway

d) Clear to within 200mm of any banks, either above or below the carriageway, where

items a), b) and c) do not apply
