Concrete floor slabs have traditionally been cast in long strips, typically 4-to-6 meters wide. These strips are layed alternatively, with infil strips being placed later. This method has several significant drawbacks - it is extremely slow, set up of formwork is critical, the resulting floor has many formed construction joints and consequently, surface tolerances, particularly across the bays, can be inadequate.

Large bay construction methods were developed to overcome these limitations. Manual hand-screeding techniques reduce the number of construction joints but highly skilled crews are required, and even then high level of flatness is not possible.

Mechanised large bay construction using a Somero Laser Screed allows very large areas to be cast as a single continuous pour, thereby eliminating the need for construction joints. Eith constant reference to a laser level, surface tolerances are optimised and are uniform in all directions.
