Pueblo was picked to house the Professional Bull Riders World Headquarters, a four-story, 48,000 square foot building. The headquarters is being built along the Historic Arkansas Riverwalk of Pueblo (HARP), which is the city's newly constructed 26-acre urban waterfront experience. Terracon provided a variety of environmental engineering, geotechnical engineering, and construction-phase testing/inspection services for the headquarters, the asphalt parking lot, and concrete retaining wall. Environmental services conducted for this project included environmental site assessments, a Health and Safety Plan, and limited groundwater and soil sampling activities for field and laboratory assessments. Geotechnical engineering services included field exploration, laboratory testing as well as Cross-Hole Sonic Logging (CSL) services, a non-destructive test that provides a generalized indication of drilled shaft concrete integrity. Our CSL logging consisted of seven individual mobilizations to the project site as well as a report of the results and recommendations to the integrity of the shafts tested. Terracon also performed construction materials engineering and testing services, which included field observation of drilled pier construction on a full-time basis during installation, field density-compaction testing, and laboratory evaluation of soils for the building, the subgrade backfill, foundation wall backfill, pavement, and site work. Terracon conducted field observations of reinforcing and structural steel, fireproofing, and asphalt pavement. We also performed field and laboratory testing of fresh concrete used during construction for the building, testing for slump, air content, unit weight, and temperature for each set.
