Type D Desktop Report Survey

Know what's on record before boots hit the ground.

What is a Type D Desktop Report Survey?

A PAS 128 Type D survey gathers existing utility records and statutory plans from utility owners. This desktop study helps identify known infrastructure before any field survey takes place.

Desktop utility records are not enough on their own, but they are an important first control and give the project team a starting point before site investigation begins.

Applications

Typically used at early project stages when assessing constraints or planning design options.
