As part of the quality control procedure, as built surveys verify the sub contractor has carried out his work to the specified tolerances. Often a request by main contractors as an independent check before follow on trades commence without delay.

Lift Shaft Verticality

ASES employ the use of Leica and Faro 3D laser scanning technology to carry out all as built surveys, the speed and accuracy of data translate into a cost effective solution without the need for return site visits, an advantage over traditional, EDM as built methods.

Measurements are translated into 2DCAD drawings that allow us to compare the as built structure to proposed drawings. Discrepancies are identified and reported to the client.

As Builts are vital for lift shafts, prior to the installation of the mechanisms, allowing installers to verify the verticality and opening size.
