TerraFirma Earth Technologies Tackles Complex Dewatering at Revé, Boulder’s Highly Anticipated Mixed-Use Community
BOULDER — TerraFirma Earth Technologies, a Houston-based dewatering firm with offices in Denver, has completed the installation of temporary dewatering and groundwater treatment systems for Revé, Boulder’s highly anticipated mixed-use development. The Revé project is located at 30th and Pearl St., across from the new Google complex. It has been four years in the making, and projected occupancy is January/February of 2021.
Revé is Southern Land Company’s first development in the Boulder market. The Reve Community will offer multiple lifestyle choices including micro, studio, efficiency, one, two, and three-bedroom, town home, and live/work residences. The plan contains 244 residences, 24,500 square feet of retail space, 108,700 square feet of office space, and ample green space and bike paths.
With the dewatering system up and running, the excavation of both the north and south parcels has successfully reached its target subgrade of 26 ft. below ground surface, despite having to perform the work throughout Boulder’s winter months. The estimated eight-month-long maintenance and operation phase of the dewatering continues and is expected to be complete by Summer of 2019.
To install the wells, TerraFirma utilized a Soilmec 312 hydraulic drilling rig to advance the 30” diameter borehole to the designed termination depth of 32 ft, easily excavating the extensive layer of sand, gravel, cobbles, and boulders. “Additionally, by utilizing the powerful Solimec 312, we were able to easily penetrate nearly 10 feet into the underlaying bedrock, creating a ‘sump-effect’ along the entire excavation footprint, which allowed us to draw down the water further,
closer to the bedrock/alluvial interface,” explained Mr. Giles.
