Caltrans Route 12
Caltrans Route 12
Project Details:
Owner: Caltrans
General Contractor: O.C. Jones & Sons, Inc.
Date of Work: June 2014 - October 2014
Engineer: Caltrans
Approximate Key Quantities: Wick Drains (2,300,000 LF)
Description:
To improve a deteriorating roadway surface and driver safety, the project proposed to replace the existing two-lane freeway with a new roadway section that includes 12-ft travel lanes in each direction, 8-ft outside shoulders and a concrete median barrier.
Ground Conditions:
The near-surface soils consist of an estimated 7 ft of loose/soft peat underlain by 5 ft of loose to very loose silty to clayey sand. To mitigate settlement, Menard and Advanced Geosolutions proposed the installation of wick and strip drains.
Solution:
Menard and Advanced Geosolutions installed a total of 177,300 LF of strip drains and nearly 2.3 million LF of wick drains along the 4-mile segment of SR 12. Facing strict deadlines by the California Department of Transportation, Menard overcame swampy, marshy conditions to complete the project on schedule.
