Design Applications and Systems

Capitalizing on the latest technology available in civil engineering design, QK has implemented the use of Autodesk, Bentley, ESRI, CartêGraph, and a number of smaller design packages. The implementation of these industry standard applications and systems allows our engineering teams to create accurate three-dimensional models of the existing and proposed infrastructure. In doing so, potential conflicts often not discovered until construction are revealed, allowing for multiple alternatives to quickly be evaluated and visualized in three-dimensions. This can greatly reduce the potential for costly change orders.
