Why Every Developer in Lagos Needs an As Built Survey Before Handover

What an As Built Survey Actually Records

An As-Built Survey documents exactly what was constructed, as it actually exists on site, rather than what the original architectural drawings proposed. Walls, columns, drainage lines, utility routes, and boundary relationships are all measured and recorded after construction is complete.

In practice, this is rarely identical to the original design. Minor adjustments happen during almost every build, whether due to site conditions, contractor decisions, or client changes mid project. An As-Built Survey captures the reality, not the plan.

Why Developers Often Skip It

By the time a project reaches handover stage, budgets are tight and everyone is eager to close out. An As-Built Survey can feel like an unnecessary final cost on a project that already feels finished. This is understandable, but it is also where a lot of future problems quietly begin.

Where As Built Data Becomes Critical Later

• Resolving disputes with neighbouring property owners over boundary encroachment
• Supporting insurance claims where exact structural positions need to be confirmed
• Planning renovations or extensions years after the original build
• Satisfying regulatory or institutional record keeping requirements

What Happens Without One

Without accurate as built records, a developer or property owner is left relying on the original design drawings, which may no longer reflect what is actually on the ground. This becomes a real problem the moment any future work, dispute, or compliance check requires precise, current data rather than the original intention.

How the Process Works

An As-Built Survey is carried out after construction is substantially complete, using the same precision instruments used for the original survey work. The resulting plan documents actual positions and dimensions, which is then kept as part of the permanent project record alongside title and construction documentation.

Building It Into Your Project Timeline

The simplest fix is to plan for it from the start. Treat the As-Built Survey as a standard part of project close out, the same way you would treat final inspections or certificate issuance. Built into the timeline this way, it adds very little delay and protects the value of the completed project for years afterward.
