Draper Aden Associates believes that construction quality control and quality assurance (QC/QA) is not just a regulatory requirement, but perhaps the most vital component of a project.  It is through quality control that our clients’ investment dollars are protected, and projects are assured of being implemented in the manner intended.  Quality control is a very specific goal in the construction environment and should meet or exceed stated requirements - the first time and in every phase or construction event.  Therefore, our commitment is to provide construction QC services in a manner that ensures contract requirements are met initially, not eventually.

Draper Aden Associates' team of certified field technicians are experienced in all aspects of construction management.  Draper Aden Associates has developed an outstanding reputation for responsive and high quality technical service, using state-of-the-art procedures to investigate, analyze and develop recommendations relating to soil, rock and groundwater.   Because our technicians thoroughly understand construction techniques, construction materials and testing methods, they can accurately represent construction documents, minimize construction delays and enhance project efficiency, all of which minimize construction costs. 

Draper Aden Associates’  geotechnical engineers are supported by our soils laboratory - one of the largest of its kind in the region.  We have provided laboratory services for over 100 different landfill construction projects with over 1,500 acres of landfill liner and cap tested.  Our state-of-the-art permeability testing equipment allows rapid turnaround time, which is essential for large, fast-paced construction projects.
