What is a Work as Executed (OSD) Plan?

A Work as Executed (OSD) plan is a precise survey that measures your drainage system after installation. The details are marked in red ink on a copy of your approved drainage plan, then issued to you for submission to hydraulic and structural engineers for final compliance certification.

This survey ensures:



Your drainage system matches approved designs



Council and regulatory requirements are met 



Engineers can issue compliance certificates without delay

Without it, your project may be stalled, and council approvals delayed.

Why Do You Need a Work as Executed (OSD) Plan?

A mandatory requirement for development consent, this plan is essential before you can:



Register Section 88E documents



Obtain your Occupation Certificate



Prove compliance with council drainage requirements

By ensuring your drainage system is surveyed and documented correctly, you can avoid unnecessary rework, compliance issues, and delays in final approvals.
