Dayton International Airport Multi-Level Parking Structure

Dayton, Ohio

The project consisted of a three-level 360,000 square feet post-tensioned parking structure. This project required testing for each building component including over 1,500 Geopier observations, soils field density tests, significant reinforcing steel observations, concrete field tests, concrete compressive strength tests, post-tension cable measurements, structural steel and welding field tests, fireproofing, and masonry tests. The owner and regulators required a high-quality product. Patriot added around-the-clock testing to accommodate the project to include early compressive strength tests for 5,000 psi concrete, hardened shrinkage tests, and the presence of corrosion inhibitors. Over 4,500 loads of concrete were tested through the course of the project.
