Multi-storey construction setout establishes precise gridlines and vertical datums that are transferred from the ground floor to every level of a building. Accuracy from the foundation up is critical.
In a multi-storey building, every column, wall, and slab must align with the level below and above. A small offset in the setout grid at ground level can grow to a significant mis-alignment several floors up.
We establish a ground level control grid using high precision instruments and verified control points. This grid is transferred to each floor using the same external network of control points as construction progresses. At every level, we mark grid intersections and vertical benchmarks for the structural contractor. We carry out checks after each floor pour confirming alignment is maintained and reporting any deviations to the site engineer while corrections are still straightforward. We remain on call throughout the construction programme: accuracy is not a day one service, it is maintained from foundation to roof.
