This is an ongoing project that requires intense attention to scheduling and manpower allocations as the flow of the project varies with project phasing. Deck pours requiring full crews are interspersed between constant daily work requiring only a single technician. Also important is the project location. This project is located in the far northwest corner of the state, far removed from the HA main office. This requires additional communication to ensure that technicians have the proper lead times to safety arrive at the project site project fit.

PROFESSIONAL SUMMARY Dwayne Culpepper has worked in the engineering and construction industry for a quarter of a century. His experience spans multiple states as an Engineering Technician. His experience includes construction materials testing and management, which is his current focus. He has worked on various types of projects including roadways, landfills, bridges, and both commercial and residential developments. Prior to joining HA, Mr. Culpepper was an Engineering Specialist IV and the Environmental Coordinator (1997-2005) at the Wellington Area Office and Childress District Office for the Texas Department of Transportation. In his capacity as Environmental Coordinator Mr. Culpepper completed all reports for NEPA and field verified most of the reporting segment of the environmental oversight process. Mr. Culpepper also inspected material batch plants, onsite and permanent laboratories and ensured that all quality control testing was completed in compliance. In order to best fulfill his duties at the Texas Department of Transportation, Mr. Culpepper had to master the performance of field testing on soils, concrete, asphalts, steel and metal structures and inspections for concrete, soil, specialized materials and implement SWPP plans. After joining Hoque & Associates Mr. Culpepper began working almost exclusively on City of Phoenix projects beginning in early 2012. In mid-2013 Mr. Culpepper was transitioned to a full emphasis on the Valley Metro Light Rail Project. Here he completed material testing for subgrade soils, aggregate base course, asphalt, and concrete, reporting, and other efforts vital to Light Rail construction. In 2014 Mr. Culpepper transitioned to a City of Phoenix Contract Consultant and continues working with the City of Phoenix during the conclusion of the 19th Avenue Light Rail Extension.
