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. C&A Surveyors did work before and after a residential development application and they arrived on time and were efficient, I can recommend their services. The documents provided were compatible with the DA approval system.

 Trustindex verifies that the original source of the review is Google. C&A Surveyors are absolute weapons. I was in a bit of a pickle and they pulled me out like it was nothing. The man turned up cool as ever, sorted the mess and had me back on track before I even finished my coffee. I swear I will never use anyone else. C&A for life.
