Project Details

Owner: Sacramento Regional County Sanitation District

Contract value: $20,919,999

Description

The project consisted of 15,000 linear ft of 108-in reinforced concrete pipe installation in southeast Sacramento. Installation required an excavation 28 ft to 32 ft deep, with the upper 12-14 ft open cut and a 1:1 slope, while the lower 18 ft received a 36 ft trench shield.

Each individual pipe section weighed more than 75,000 pounds, making it necessary to use a 200 ton crawler crane to install the pipe. Two sections of the project were installed by jack and bore. Approximately every 1,000 ft, a manhole structure was installed, and the southernmost end of the pipeline ties into an existing junction structure.
