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.

 Trustindex verifies that the original source of the review is Google. Very professional people. I was dealing with Melik, I thought it would be impossible to get the survey plans ready within a week, he assured me it would be ready and before a week it was ready and perfect. I highly recommend c and a Surveyers.

 Trustindex verifies that the original source of the review is Google. What an experience. From start to finish. Building and developing can be stressful enough as it is but using a company like C&A definitely can reduce that stress. Can’t speak highly enough of the whole team at C&A.. They were very professional and on time every time and were extremely helpful through the entire process. Special thanks to Celso who was awesome to deal with on site
