Project Details

RAWSO landed the contract for this multifamily residential complex in May 2020. This large project includes four building pads for four-story structures, a maintenance building, an amenity area, and a dog park. RAWSO’s responsibilities on this job include earthwork, storm drainage, sanitary sewer, and water.

We encountered a complicating factor on this project when we discovered existing utility lines that were not marked on the original drawings. This required us to immediately deviate from the plans to work around these unexpected obstacles. We will also need to acquire a lane closure permit to construct the off-site storm drainage facility. Due to the job site’s urban location, safety and efficiency are vital for the successful completion of the project.

The Alta Union project will require our crews to import roughly 8,000 cubic yards of fill. We will also install about 2,500 linear feet of storm drainage with 34 storm structures, along with 535 LF of roof drain with 12 cleanouts and 1,100+ LF of sanitary sewer with eight cleanouts and five manholes. Additionally, RAWSO will install roughly 2,800 combined LF of water main, domestic, and irrigation lines.
