Client: Metropolitan State University of Denver
Overview: Metropolitan State University of Denver completed a new sports facility in 2015 for their baseball, softball and soccer teams, as well as tennis courts and running paths. The facility is located south of the Colfax Avenue viaduct adjacent to Shoshone Street and east of Interstate 25 in Denver, Colorado.
The project site is a redevelopment of a major Brownfield, with both surface and groundwater contaminants. Due to the environmental issues at this site, typically the area would need to be excavated and the contaminated soils removed and replaced with suitable import fill materials.
Therefore, Deep Dynamic Compaction, almost unheard of in the Denver market, was used to densify soils. Deep Dynamic Compaction is a ground improvement technique that densifies soils and fills in-place by using a drop weight. Full-time air monitoring and daily visual survey of impact craters were performed, in order to determine when localized remediation or additional engineering controls were needed.
Services Provided: On-site environmental inspection services, testing and management of both asbestos and chemical contaminants unearthed during excavation; successfully entered the client into the State of Colorado Voluntary Cleanup Program
