Civil engineering links the proposed development to its site: levels, access, drainage, earthworks, retaining and infrastructure interfaces may all need to be resolved in the context of an approval pathway. AHD provides project-specific engineering support and coordination across WA, including regional and remote sites, and Victoria. The service can support development and infrastructure questions across WA, including regional and remote sites, and Victoria. AHD’s role is to help define and coordinate the civil engineering issues for the actual site and project stage, not to promise a fixed design package, statutory result or in-house delivery of every specialist discipline.
Build the brief from site information
A useful civil brief identifies the proposed works, jurisdiction, title or cadastral information, available feature survey, existing services, levels, planning material and authority correspondence. That information helps determine whether earthworks, vehicle access, drainage, retaining, verge, road or public-asset interfaces need to be considered. Conditions such as groundwater, contamination, flood exposure and soil type must be established for the particular site, not assumed from its address. A feature survey, cadastral or title information, service information and planning material can help establish constraints before engineering documentation is developed. The required depth of review depends on the proposed works and authority pathway. Surveying can establish measured site information, while geotechnical advice can inform ground assumptions; AHD coordinates those external specialist inputs where engaged, and their deliverables remain separately scoped.
Drainage and earthworks need coordinated decisions
Stormwater, groundwater, site levels and overland flow can influence development planning and engineering documentation. WA guidance provides resources for subdivision and development drainage, while local governments can have their own supporting-information requirements. Earthworks may include fill, excavation, backfilling, retaining and re-compaction; a published Serpentine Jarrahdale process illustrates why the actual local-government pathway must be checked rather than generalised across WA or Victoria. WA Government resources address stormwater-management decisions, urban water management plans, groundwater control and floodplain mapping for subdivision and development planning. Those resources point to the importance of coordinating runoff, water and levels with the site and authority requirements, but they do not establish groundwater, flood or drainage conditions at an individual property. The appropriate investigation must be selected for the actual proposal.
Authorities and external specialists have distinct roles
For WA subdivision, WAPC approval and local-government engineering review or clearance can sit alongside one another. Planning authorities and local governments make statutory decisions; AHD’s documents can support the agreed technical scope but do not guarantee an approval. AHD coordinates third-party geotechnical, surveying and drafting specialists where required, with each discipline separately scoped rather than supplied as an in-house service. For WA subdivision, the WAPC is the approval authority, while local-government engineering review or clearance can sit alongside that process. Roads, drainage, pathways, earthworks and public-open-space interfaces may be relevant at different stages. A Serpentine Jarrahdale earthworks process and the Mandogalup West Stage 18 LDP are local, plan-specific examples only; neither should be applied to every WA, Victorian or Mandogalup site.
Discuss your project
Start with the information you have.
Send the project address, a short description of the work or concern, and any plans, photographs or authority correspondence. AHD can then discuss the appropriate next step for the agreed scope.
