Construction Layout Survey for Office Complex

Every Pour, Plumb and Bolt — Verified

Alder & Finch Builders engaged us from excavation to curtain wall for a three-storey office complex: building grid, foundations, anchor bolts, steel lines, façade control and final as-builts.

Across fourteen months and nine phases, not a single concrete pour was delayed by layout — and the bolt survey caught two misalignments before steel arrived on site.

Tight Tolerances, Live Site

Anchor-bolt tolerances under half an inch, a crane-swing corridor crossing the control network, and concrete scheduled in night pours meant layout had to be right, protected and available around the clock.

Control That Survives Construction

We set redundant control outside every work zone, verified bolts the evening before each pour, and kept a 24-hour re-stake promise — two caught misalignments fixed before they became change orders.
