Part 2: Developing cost estimate using benchmarks
10 Guide for councils
10.5 Worked examples of applying the benchmarks
10.5.1 Infrastructure Cost Template
Figure 10.3 is a sample Infrastructure Cost Template that councils could use to estimate the cost of infrastructure items. It is not necessary for councils to use this template, however we suggest that councils provide the level of information outlined in the template as a minimum. Adopting a common approach to estimating and provide information in a similar way will encourage consistency and transparency in the preparation of local infrastructure plans by councils across the state.

Local Infrastructure Benchmark Summary Tables Contents
Item Name: Item Number: Functional Description: Key Scope Assumptions: Sub Item: Pricing Methodology: Standards: Values Table: Contractor's Indirect Costs: Margin: Council "On-Costs":
Displays the benchmark base cost for each Benchmark Item / Sub Item. The benchmark base cost includes an estimate of Direct Cost, with a fixed percentage mark-up applied for Contractor's Indirect Costs, Margin and Council On-Costs. The fixed percentages are detailed in the Assumptions table.
Benchmark Summary Tables
There are 58 Benchmark Summary Tables - one for each Benchmark Infrastructure Item from the Infrastructure List for Benchmarking (Benchmark List).
Each Summary Table contains the following fields:
Name of the item included under one of the four categories on the Benchmark List.
Number unique to each Benchmark Item.
Detailed description of the Benchmark Item.
Key assumptions made in the estimation of cost for the Benchmark Item.
A variant of a Benchmark Item with differing configuration, arrangement, size, material or performance.
Refers to the approach taken in estimating the cost benchmark for the Benchmark Item / Sub Item.
Refers to industry accepted design standards or guidance relevant to a Benchmark Item / Sub Item.
Assumptions
Consisting of the Contractor's preliminaries, management & supervision and design (if applicable).
Consisting of the Contractor's overheads and profit.
Council On-costs include: - Council's internal staff costs - Project management and design fees - Land costs, levies and other charges
The Assumptions table contains the percentage mark-ups applied to the estimate of Direct Cost costs for Contractor's Indirect Costs, Margin and Council On-Costs. The percentage mark-ups may vary depending on the specific Benchmark List infrastructure type (transport, stormwater, open space embellishment and community facilities).
