As-Built Surveys & Utility Mapping
As-built surveys for buildings and utilities for commissioning. Underground utility mapping before trench backfilling.
Service Essence
As-built surveys are a mandatory part of construction documentation, confirming that the structure was built according to the design. We measure and document the actual position of buildings, utilities, and landscaping after construction completion. Underground utility as-built surveys are especially critical — water supply, sewerage, gas, electricity, communication cables. These measurements MUST BE DONE BEFORE trench backfilling, as utilities become invisible afterward. We work promptly and are ready to arrive on site at short notice. As-built survey documentation is required for building authority approval, commissioning, and ongoing utility database maintenance.
Work Process
Request
We receive information about the site and work type. For underground utilities — we coordinate arrival time before backfilling.
Surveying
We perform precise geodetic measurements with total station or GPS. We record coordinates, elevations, depths.
Photo Documentation
We take photographs referenced to measurement points. Especially important for hidden works.
Documentation
We prepare as-built drawings, coordinate lists, and compliance reports for building authority.
