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. Totally satisfied with C&A Surveyors, fully recommend their services. Their professionalism, care, time management, friendliness and knowledge was all in display not matter who I talked to in the process of organising, performing, billing and reporting on the requested survey. Even after I had received the signed Surveyor's report, Melik was more than happy to answer my questions and provide sound advice in matters related to the survey report. Anybody wanting a survey on the property for whatever the reason, they should consider hiring these guys as they are top-notch! Thanks, C&A Surveyors!
