As-constructed records ·
Subdivision handover: who gets which records
A checklist for developers in Busselton and Bunbury, built on what Water Corporation publishes and what to ask your council.
Project Prime · Practical checklist

Start with who receives what
A subdivision hands different records to different owners. Water and sewer assets go to Water Corporation. Roads and drainage go to the local government that will receive them. List each receiving authority at the start of construction, and ask each one for its current requirements in writing, because the project conditions decide what applies to your job.
What Water Corporation’s Developers Manual asks for
Version 2.8 of the Developers Manual says as-constructed drawings are certified as-constructed and signed and dated by the Design Engineer, the Superintendent and the responsible Surveyor. The completed plan is submitted through Water Corporation’s website within eight weeks of a successful final takeover inspection. Its drawing standard is the WCX CAD Standard. Check you are using the current version.
Know the information each asset type needs
The manual points water plans to Design Standard 63 and sewer plans to Design Standard 50, and asks for the number of valves, hydrants, maintenance shafts, access chambers and lots served to be shown separately. It also asks for a contour plan where earthworks have changed a contour by 0.5 metre or more. Build your records list from the manual, not memory.
Get through the final inspection
Water Corporation asks the construction engineer to complete and submit the pre-handover checklist before booking the final handover inspection, and an asset inspector then inspects the works. Collect survey records, asset details, drawing revisions and photographs before you book, so gaps are fixed while the crew is still on site.
Plan for what comes after takeover
The manual says the developer remains responsible for rectifying differences between the accepted final design and what was built, and Water Corporation can ask for rectification if the as-constructed drawings show non-compliance. A 12-month warranty period starts at takeover. Accurate records at handover reduce the chance of a rectification request later.
Ask your council what format it wants
Local governments set their own requirements for road and drainage as-constructed data. Some WA councils, the City of Karratha among them, have joined the A-Spec program for digital as-constructed data, with R-Spec for roads and D-Spec for drainage. Ask the council receiving your assets whether it uses A-Spec, which version applies and how the data is submitted.
Keep one issue record
Record what was submitted, to whom, when and what comments remain open. Preparation and acceptance are different steps, and neither authority’s acceptance is something a consultant can promise. A single register stops two versions of a plan reaching two owners. Give each authority only the version meant for it, and keep the transmittal. When a comment comes back, log who raised it, which sheet it affects and who owns the fix. Allow time in the programme for questions and resubmission.
Where Project Prime fits
We prepare as-constructed packages for South West subdivisions, for Water Corporation WCX and for local-government road and drainage records, for developers in Bunbury, Busselton and surrounding towns. We prepare against the requirements the receiving authority nominates for your project. Acceptance stays with the authority. Tell us the job and the handover date and we confirm scope and fee.
