Denver Broncos Practice Facility Helical Soil Nail Shoring-PPT Presentation

PPT Presentation

Pdf Summary

The Denver Broncos Training Center expansion in Centennial, Colorado, used helical soil nails to shore the practice-field area and helical piles to underpin the project.<br /><br />The soil nails consisted of 1.5-inch square bars, each 10 feet long with four 10-inch helices and a hex-shaped end cap. A high-tensile-strength wire mesh facing supported the shoring wall. Underpinning piles used 3-inch-diameter, 0.25-inch-thick shafts with 8-inch and 12-inch helices, and were approximately 25 feet long. Pile load testing was also conducted.<br /><br />Construction faced delays related to steel erection, coordination with other work, a glycol system beneath the practice field, and rainwater ponding. Despite these challenges, the project stayed on schedule, came in on budget, and was considered successful by all parties.
