St. Anthony Hospital is a 673,000 sqft. 563 bed level 1 trauma facility. The previous hospital named St. Anthony Central Hospital was located in the Colfax area of Denver. The new St. Anthony Hospital was constructed in the Denver Federal Center located in Lakewood, CO. This new location better provides coverage and patient care for the west side the metro area. Building construction began in June 2009 on the 30 acre campus, opening its doors in June of 2011.
This project had several challenges as the accelerated schedule required many crews all working at the same time. During the drilled piers construction, four different drill rigs and crews were performing work simultaneously. As the structure came out of the ground, high strength columns were utilized to support the structure and increase square footage. Floor decks were all poured with a high slump, low shrink concrete mix that was required to be placed with concrete pump trucks. The line on these pump trucks extended out to 400 feet in some cases. The infrastructure and exterior concrete were all placed with Colorado Department of Transportation Class D concrete.
Bestway Concrete worked with the caisson drilling company to coordinate the four different drill rig crews. We dedicated a quality control / site supervisor to this project. We coordinated trucks coming on to the site based on a color code system we devised and shared with the contractor. Each caisson rig was fitted with a specific colored flag that was corresponded to a matching color on our delivery ticket. This allowed for proper concrete utilization and decreased concrete loss. The lightweight mix was specifically designed for the flatwork contractor allowing for a high slump flowable mix, which pumped easily and finished perfectly. In order to supply the high rate of placement, we dedicated a plant to this project on placement days. Utilizing 40 trucks to provide concrete at a rate of 150 cubic yards per hour. Dedicating a quality control person to this project enabled us to make sure all concrete was in specification and workable for all of the contractors on site.
