A structure is only as sound as its individual materials. DDS performs testing and inspection services at project sites and at our in-house laboratory to verify that those materials meet project specifications.  

Our staff is comprised of certified technicians and inspectors experienced in earthwork, foundations, paving, structural concrete, reinforced masonry, and structural steel construction. DDS performs Special Inspections as outlined in Chapter 17 of the International Building Code (IBC), published by the International Code Council (ICC).  DDS’s commitment to provide certified inspectors gives you, the owner, the comfort of knowing that your inspector is competent in verifying that code requirements are being met on your project. 

DDS has over forty years of experience performing construction inspection and, with this experience, we have learned that communication and coordination within the project team is the key to a successful project.  It is absolutely essential to have an open line of communication between the contractor, design professionals, public officials, and the inspectors.  This strategy is implemented on every project to ensure a high quality finished product.  

Additionally, Our 1,400 square foot geotechnical and construction materials testing laboratory is equipped to perform numerous soils, rock, concrete, masonry, aggregate, and asphalt testing procedures. Tests are performed in general accordance to applicable ASTM or AASHTO standard test methods. DDS’s laboratory has received accreditation through the AASHTO Accreditation Program (AAP), validation through the United States Army Corps of Engineers (USACE) Validation Process, and

has been certified by the Kentucky Transportation Cabinet Laboratory Qualification Program to perform concrete acceptance testing services on KYTC projects.
