Sunroc was recently awarded the Associated General Contractor (AGC) of Utah’s Top Highway Transportation Utility Division Project of the Year for its work on the SR-18 South Bluff St Pedestrian Tunnel.
The St. George, Utah, project consisted of two phases. During Phase 1, Sunroc excavated and placed precast box culverts that were 18′ by 13′ with a total length of 188’ to form a pedestrian tunnel under Bluff Street. Each concrete precast section weighed 56,000 pounds.
Phase 2 of the project included the trail system connection and pedestrian tunnel structural concrete. 14,500 cubic yards of dirt were excavated, along with grading, storm drain pipe, road base placement, and asphalt paving all taking place. Additionally, 120 cubic yards of structural concrete headwalls were poured, and electrical and fencing was installed.
Traffic was detoured throughout the duration of the project in order to meet the 15-day timeline set by the city. Vehicles were redirected away from the construction zone which helped keep the installation on schedule.
Challenges on the project included the coordination between working with suppliers, subcontractors, and the owner to make sure deadlines were met. Sunroc was able to problem solve quickly to help complete the project on time.
Congratulations to all involved on this prestigious award!
