Our design philosophy emphasizes a comprehensive approach with attention to detail. All engineering projects are completed using a design-centric process as opposed to a drafting-centric process by starting from the ground up and employing an intelligent 3-D project model to design the project geometrically in both elevation and plan that concludes with construction documents. This method allows for the complete integration of the proposed improvements with the existing conditions. Advantages include the ability to iteratively design, visualize and optimize the project thereby resulting in a more efficient, economical, and robust design. Additionally, as a result of this method of work, all projects are suitable for use by contractors for construction layout and machine control using electronic data transfer without any additional computations.
