Before you buy a development site: civil engineering checks that matter
A Sunshine Coast development site due diligence guide covering access, stormwater, services, easements, slope, overlays and hidden civil costs.
Short answer
Before buying a Sunshine Coast development site, check the civil issues that can affect yield, cost and timing. The most important early checks are access, stormwater, services, easements, overlays, slope and constructability.
These are the issues that often sit outside the real estate brochure but inside the developer's margin.
Start with the site information
Use council's Development.i tools, site report, mapping, planning scheme information and nearby approvals to understand the public record. Then compare that with title documents, registered plans, survey and what is visible on site.
A quick map review is helpful, but civil risk usually becomes clearer when levels, services and access are considered together.
The checks that matter most
Review where vehicles can enter, whether sight distance is practical, how stormwater discharges, whether sewer and water can be connected, whether easements cross the site, how much earthworks may be required, and whether overlays affect the same area needed for access or buildings.
For small developers, focus on constraints that change yield or require expensive works.
How to use the findings
A due diligence review should produce decisions, not just observations. It should tell you what appears workable, what needs more investigation, what could cost money and what assumptions should go into the offer price.
Sometimes the best outcome is confidence. Sometimes it is a renegotiation. Sometimes it is walking away before a bad site becomes your problem.

FAQ
Common question
What should a civil due diligence review cover?
It should consider access, stormwater, levels, earthworks, services, easements, overlays, road frontage, constructability and obvious approval-condition risk.
Can civil due diligence confirm a site will be approved?
No. It is not an approval guarantee. It helps identify practical risks and cost drivers before purchase or major design spend.
When should I do it?
Before going unconditional where possible, or at least before committing to a fixed layout, purchase price or development feasibility model.
