Engineering supervision of an off-plan sales project shares inspection and acceptance with ordinary supervision, but adds direct regulatory responsibilities to the Real Estate General Authority (REGA). The supervisor here does not answer to the owner alone; it signs off the release of buyers' money, submits public reports, and must report violations within a set period. Anyone who misses this difference may treat a Wafi project like any ordinary project, and disbursements are delayed or liability is called into question. This guide compares ordinary supervision with supervision in Wafi, explains what this means for the developer, and how to build a supervision system that meets the requirements.
Comparison
| Item | Ordinary supervision | Supervision in Wafi |
|---|---|---|
| Relationship | With the owner | With the developer, with obligations to the authority and buyers |
| Payments | Approves the contractor's invoices | Certifies escrow disbursement documents with the accountant |
| Reports | To the owner | Project progress reports to the authority monthly or quarterly depending on size |
| Violations | Informs the owner | Notifies the authority within 5 working days of becoming aware |
| Disclosure | Internal | Its reports are public in the projects database |
| Qualification | The office's licence | Article 6 conditions: a qualification programme and classification for large projects |
| Defects | Under the contract | Defects found prevent release of the amount retained in the escrow account |
What Does This Mean for the Developer?
Choosing a strong, independent consultant is not a burden but a guarantee of smooth disbursements and buyer confidence, because its reports are public. A project whose reports show steady progress earns market trust and makes it easier to sell the remaining units.

Frequently Asked Questions
Can the consultant be changed during the project?
This is subject to the authority's rules and the project agreements; in handling a troubled project, the authority's committee may require the developer to replace those responsible.
Does the consultant bear liability?
The regulations state that permission to withdraw the surplus does not relieve the developer, the consulting office or the accountant of liability at any stage.
Does a Wafi project need a resident engineer?
It depends on the project's size; large projects usually need one to ensure accurate measurement and documentation. Read: When is a resident engineer necessary?.
What if the developer and consultant disagree on the progress percentage?
Documented site measurement is the reference, and the consultant is bound by its regulatory obligations to the authority.
Does the consultant review material quality?
Yes, as part of inspection and acceptance, because defects prevent release of the retained amount.
