Priced to WA Authority Specs
Civil works estimating in WA requires knowledge of local authority specifications, current WA plant rates and the specific material standards that apply to roads and drainage in the Perth metropolitan area. An estimate built on interstate civil rates or generic national specifications will be wrong on a Perth local government job.
We estimate civil works for Perth civil contractors, covering road construction, stormwater drainage, kerb and gutter, footpath and shared-path construction, carpark development and subdivision civil works. WA rates, local specifications, properly measured quantities.
Civil Works We Estimate in Perth
| Civil Element | What We Measure | WA-Specific Notes |
|---|---|---|
| Road base and subbase | m3 by compacted depth and area | MRWA or local authority specification applied |
| Asphaltic concrete | Tonnes by compacted depth and m2 | Mix type by traffic loading classification |
| Kerb and gutter | LM by kerb type, standard, barrier, roll-top | MRWA or local authority standard drawings |
| Stormwater drainage | LM of pipe by diameter, pit item counts | WSUD requirements for post-2012 Perth subdivisions |
| Footpath and shared paths | m2 by width and surface type | DPI and ARUP path standards for cycling routes |
| Culverts | Item by type, size and inlet/outlet treatment | Inlet protection and headwall included |
| Line marking | LM by line type and width | Retroreflective vs standard specification |
| Street furniture and signs | Item count by type | AS 1742 specification references |
WA Civil Engineering Standards
Civil works in Perth must comply with MRWA (Main Roads WA) specifications for road construction, and individual local government authority standard drawings for drainage, kerbing and footpaths. Standards differ between City of Swan, City of Joondalup, City of Fremantle and others. We reference the correct authority specification for each project before any quantity is priced.
Every Layer Is a Separate Number
A road is not one item. It is a stack of layers, each with its own compacted thickness, its own material rate and its own compaction and testing requirement.
Price the pavement as a single square metre rate and the first thing that moves on site, a deeper subgrade box, an extra base layer, a change in mix type, has nowhere to go except your margin.
What We Separate Out
- Subgrade box out and spoil disposal volumes
- Geotextile area where sand subgrade needs it
- Subbase and base course by compacted depth
- Asphalt tonnage by mix type and compacted thickness
- Kerb by profile and linear metre
- Drainage pipe by diameter, plus pit and lintel counts
- Compaction testing and proof roll hold points
- Traffic management and staging where the road stays live

The Specification Decides the Price
Two councils can want the same looking road and specify it completely differently. Different base depth, different mix, different kerb profile, different testing frequency.
That is the part interstate rate cards and generic estimating software cannot carry. The quantity is only half the answer, the specification behind it is what turns the quantity into a real cost.
We check which authority the job sits under and price it to that standard drawing before anything else happens. If the documents are silent, we tell you what we have assumed instead of hiding it in a rate.
Road Construction Estimating
Road construction in Perth typically involves subgrade preparation, geotextile fabric in problematic sand areas, granular subbase, road base, and asphaltic concrete surface course. Each layer has a compacted thickness specification and a different material rate.
- Subgrade preparation: scarify, compact and proof roll
- Geotextile fabric supply and installation
- Granular subbase: crushed limestone or CMDG by specification
- Road base: CMDG20 or DG40 to MRWA specification
- Asphaltic concrete: AC10 or AC14 surface course by traffic loading
- Primerseal or primecoat to MRWA specification
- Heavy duty pavement for industrial hardstands

Stormwater Drainage Estimating
Stormwater drainage estimating involves pipe quantities by diameter, pit item counts by type, trench excavation volumes, bedding and backfill quantities, and all the connections, bends and junctions in the drainage system. Each of those items is a real cost on a civil job.
- 01
Civil Drawings Received
Road design plans, drainage design, utility plans and any local authority or MRWA specification applicable to the project.
- 02
Quantities Calculated
Pavement areas and volumes, drainage pipe lengths, pit counts, kerb runs and footpath areas measured from calibrated drawings.
- 03
Specification Referenced
MRWA or local authority specification applied to each element. Variation from standard specification noted as a cost difference.
- 04
WA Rates Applied
Current Perth plant hire, material supply and labour rates applied. WA-specific rates for asphaltic concrete, crushed limestone and drainage materials.
- 05
Estimate Delivered
Structured by element type (earthworks, pavement, drainage, kerbing and footpath) so you can compare subcontractor prices on each package.
Common Questions
Straight answers on how we price civil estimating in Perth. If yours is not here, send your plans and just ask.
Yes. Subdivision civil works are a common estimating package, covering lot clearing, earthworks, roads, drainage, kerbing, footpaths, reticulation trenching and service conduits. We can estimate the full civil scope or individual trade packages.
Yes. Road works within the MRWA network, or works adopting MRWA specifications, are estimated with reference to the current MRWA specification suite and standard drawings. Local government works reference the relevant local authority specifications.
Yes. Carpark civil works include earthworks, subbase, road base and asphaltic concrete or concrete pavement, drainage, kerbing, line marking and signage, all estimated as a complete scope or by trade package.
Yes. On commercial developments that include both building works and site civil, we can estimate the civil and building trades together. Civil packages typically include earthworks, pavements, drainage and services infrastructure.
