Construction depends on the survey that puts the design on the ground: setting out foundations, structures, roads and services to the correct position, line and level, then verifying as the work proceeds. Survey House provides this for surface infrastructure on mines and for civil and construction projects generally.
The work spans the full project life — establishing site control, setting out the works from the engineering drawings, monitoring during construction, and capturing accurate as-builts. The group has set out and designed major access roads, so the discipline runs from greenfield earthworks to finished structures.
Where the original design and the as-built must be compared, scanning and conventional survey are combined for a complete quality check. The same rigour applied to shaft steelwork is applied to concrete, structures and earthworks.
Control is established across the site or along the corridor and closed rather than run open. On linear work an unchecked traverse can drift over distance with no indication that it has.
Setting out is checked independently of the person who set it. Constructed work is verified against design and deviations reported with position and magnitude, rather than as a pass or fail.
As-built capture on buried services has a short window. Once a trench is backfilled the only record is what was surveyed while it was open. Recovering that later costs considerably more than capturing it at the time.
