Laser levels in construction

Published by Strada Imaging on

Have you ever wondered how tall structures, like the one below, stand vertically, I mean, really vertically?

That is because today’s construction engineers use various levelling and distance measurement instruments to keep buildings and structures to their intended form and shape. Imagine using the tech of the olden days to build Skyscrapers; how precarious these 5-storeyed buildings look like!

Modern optical levels (Figure 3) are used in conjunction with a staff (a.k.a a levelling rod) to ensure that floor surfaces are flat and to a given accuracy.

A second staff is used to keep track of everything with respect to a datum point. The precise nature of the calculation is facilitated by a dedicated module in our GroundApp.
