2.1 Guide to the KRA Performance Framework
2.1.1 Introduction
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.

TOTAL 100%
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.
Appendices (WBoPDC Local Roads)
1 Value Management Proposition
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.

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.

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

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.

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)
$1,274,229

3.2.2 Underslip Minimum Repair Standard Specification
The Contractor is required to repair any underslip to a minimum width of 0.3m from the
outside of the original edge of the seal or carriageway (prior to the slip) plus an additional
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.

Speed Zone >80 km/hr 50 to 80 km/hr <50 km/hr
0.5m 0.3m 0.0m
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).

Representative.
4.1.8 Asset Register Data
WBoPDC staff will be given access to view all data and have reporting capability in the
Contractor‟s RAMM database.
4.1.9 Pavement Deterioration Modelling
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
Reporting will be on an as required basis as requested by the Engineer‟s Representative.
Reliability Statement
A statement on the reliability and usefulness of the system shall be included.
Utilisation of Outputs
Appendices (WBoPDC Local Roads)
1 Management Performance Measures
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.
Ongoing performance reporting will be summarised to allow year on year comparison.
The report will also include any relevant commentary.
The Delivery Time shall be 30 June of each year of the Contract.

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
Appendices (WBoPDC Local Roads)
1 Management Performance Measures
Page 43 of 157
4 d) Identify activities for which permission must be obtained before undertaking any
work
e) Identify the appropriate protective measures to be used
f) Identify any standard practices for environmental risk mitigation
g) Identify any emergency procedures for dealing with accidental pollution or imminent
danger.
The EPP shall as a minimum address:
i) Each specific consent requirement and condition
ii) Dust control at work sites including:
Highlighting that one of the most likely causes of dust damage is sweeping before
sealing is carried out
The particular susceptibility of kiwifruit grown within the region to dust damage
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.

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
Appendices (WBoPDC Local Roads)
1 Management Performance Measures

Appendices (WBoPDC Local Roads)
1 Management Performance Measures
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:
Appendices (WBoPDC Local Roads)
1 Management Performance Measures
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.
Appendices (WBoPDC Local Roads)
1 Management Performance Measures
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.
Appendices (WBoPDC Local Roads)
1 Management Performance Measures
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
Appendices (WBoPDC Local Roads)
1 Management Performance Measures
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

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.
Appendices (WBoPDC Local Roads)
1 Management Performance Measures
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.

5 5.5 Network Video
A video of the entire network, both sealed and unsealed shall be collected by the
Contractor each year. The purpose of the video is:
a) To have a historical record of the roading network
b) To have them available for consultants and other interested parties to use for
obtaining further information within the roading corridor
c) Provide evidence of road condition and deterioration
A sample video shall be provided to the Engineer‟s Representative for acceptance prior to
surveys commencing.
5.5.1 General Requirements
Video shall be captured using a minimum of one 3-CCD digital camera with wide angle
lens (60-70° horizontal field of view). All equipment used is to provide high quality colour
recording at normal survey speeds. The camera shall be dipped at 3°- 6° and aligned
parallel to the centre of the vehicle axis. The camera is to be fixed focus, with an
accurately calibrated lens-camera-image combination to allow height/width measurements
to within 0.2 metres). The shutter speed must be sufficient to minimise motion blur.
Particular consideration must be given to the mounting of the camera to minimise
vibration.
The minimum requirements for the network video survey equipment are:
Table 5.5.1 a): Network Video Minimum Requirements
Parameter Minimum Requirement
File format Current technology
Image height 768 pixels
Image width 1360 pixels
Audio recording No
Video interlacing Non-interlaced (i.e. progressive scan with no duplicated lines and no “field motion”)
Video quality High
The images are to be recorded with time stamp capabilities in a separate electronic file.
Images are to be indexed by either frame numbers or time stamp which are stored on the
video and synchronised to the true position data of the vehicle at all times (i.e.
displacement is to be rubberbanded to true network length). The file created shall be an
ASCII file in the following format, with the frequency of record creation agreed with the
Engineer‟s Representative:

3 Direction (I, D or null) char (1)
4 File reference char (25) no nulls
5 Frame number or time stamp no nulls
6 Date of recording ddmmyyy no nulls
All distance measuring equipment must be validated on an odometer calibration test track
in accordance with the NZTA Location Referencing Management System Manual. If an
already established odometer calibration test track is to be used, the Contractor must
supply confirmation from a Registered Surveyor that the calibration test track meets the
dimensional tolerances specified in the NZTA Location Referencing Management System
Manual. The Contractor must then measure the length of the test track at least 5 times
using the distance measuring equipment. The distance measuring equipment is validated
when all the measurements are within ±0.05% of the reference distance.
5.5.2 Survey Requirements
Network videos of all WBoPDC Local Roads must be performed:
a) Once annually on each sealed and unsealed carriageway in road groups 1 to 7
b) In each lane direction as a continuous survey
c) During period of fine weather with light conditions appropriate to provide good
quality video
d) Such that the lane width and roadside furniture are captured
e) Such that no part of the survey vehicle appears in the video
f) To be completed in the final quarter of each period (Mar/Apr/May)
The Contractor must record and report the route position of all network video survey data
to an accuracy of:
±(0.3% x D + 10m), for 100% of roads
±(0.25% x D + 10m), for 95% of roads
where:
D = the distance from the start of the road as defined in the WBoPDC RAMM
database.
The surveys must start at the commencement of the road as defined in the WBoPDC
RAMM database. The start point must be recorded and the distance measuring equipment
set to the start point distance, usually 0. If the distance measurement at the end of the road
Appendices (WBoPDC Local Roads)
1 Key Performance Measures
Page 82 of 157
5 is not within the specified tolerance, the Contractor must resurvey the road. The re-survey
must note any difference in the measurement point locations. If the second survey
confirms the initial survey, the Contractor must notify the Engineer‟s Representative
immediately and develop a remedial proposal for agreement with the Engineer‟s
Representative.
All data collected for each road is to be rubber-banded to adjust for the difference between
the measured length and the true length.
5.5.3 Data Requirements
Three sets of all data for each survey must be provided on media agreed with the
Engineer‟s Representative.
If review of the data by the Engineer‟s Representative reveals discrepancies, quality issues
or other problems in the data, the Contractor must correct the error and redeliver the data
within 5 working days, which may include resurvey if directed by the Engineer‟s
Representative.
5.5.4 Reporting Requirements
All data delivered for each survey must be accompanied by a Survey Data Report
containing the following information:
a) Results of compliance monitoring completed
b) Data quality check sheets
c) Distance measurement discrepancies (i.e. any roads where the measured distance was
outside the allowed tolerance and actions taken to verify true length)
d) Equipment failures or replacements
e) The actions to address the above problems and steps taken to ensure the quality and
reliability of the supplied data
The Survey Data Report must be signed off by the Contractor‟s Representative to confirm
that all survey and data processing has been completed in accordance with this
specification and the Contractor‟s quality assurance procedures.
The Contractor shall prepare a report detailing:
i) Equipment descriptions, specifications and configuration
ii) Distance rubber banding procedures
iii) Format and description of all raw data
iv) Correction procedures that were applied and how

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 5.20 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 5.22 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 𝑆𝑖𝑔𝑡 𝐷𝑖𝑠𝑡𝑎𝑛𝑐𝑒 = 𝐿𝑒𝑛𝑔𝑡 𝑤𝑒𝑟𝑒 𝑆𝑆𝑆𝐷 < 𝐴𝑣𝑎𝑖𝑙𝑎𝑏𝑙𝑒 𝑆𝑖𝑔𝑡 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 –

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.
Appendices (WBoPDC Local Roads)
1 Operational Performance Measures
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
The height of grass must be maintained between a minimum height of 20mm and a
maximum height of 75mm.
Type D
The height of grass must be maintained between a minimum height of 20mm and a
maximum height of 75mm. Grass clippings shall lie where they fall.

1 Operational Performance Measures
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
The height of grass must be maintained between a minimum height of 25mm and a
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
The height of grass must be maintained between a minimum height of 100mm and a
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

built scrub washer that removes surface grime, dirt and dust, via applied water, including
the substantial removal of any applied water and contaminants.
A swept surface is the mechanical and/or hand process that collects and removes loose
detritus, debris, leaves, litter, grit and the like, (but excludes adhesives such as chewing
gum), to ensure the required surfaces are fit for their intended purpose and includes
footpaths and kerb and channel: Note that hand sweeping will be required around blisters
to augment suction cleaning of kerb and channel.
