South Intermodal Yard Pavement Repairs (98)
This project was for pavement and drainage repairs in the South Intermodal Yard at the Port of Tacoma. This area consists of large paved areas which provide access to double-stack railcars for the loading and unloading of 20, 40 and 44 foot shipping containers. The South Intermodal Yard has four sets of railtracks, each about 3,000 feet long; large paved areas adjacent to the railtracks are used to move the loaded and unloaded containers using 90 ton capacity side loading straddle trucks.
The paved surfaces in the South Intermodal Yard were originally constructed with 17-inch thick Roller Compacted Concrete (RCC) trackside loading bays adjacent to the railtracks, with a 12- inch RCC pavement in the central area between the trackside loading bays. Due to changes in the configuration and capacity of the loading equipment, the 12-inch thick RCC pavement has experienced widespread failure over the past fifteen years. Washington Engineering performed a Pavement Management Survey and established a 4- year, $3 Million phased repair plan.
The first phase of this project removed approximately 1,200 square yards of deteriorated RCC pavements and constructed new 18-inch thick reinforced portland cement concrete (PCC) pavements. Additional repairs will be performed in the period from 1999 to 2001. These repairs will provide a level surface to improve operational safety.
Key Project Features:
- Constructed Portland Cement Concrete Rail Track Crossing
- Removed failed RCC sections and constructed 18-inch thick Reinforced Portland Cement Concrete Sections
- Developed repair plan for future work including asphalt repairs, PCC repairs and storm drainage improvements
- Prepared CAD Drawings, Specifications and Cost Estimates
- Provided Construction Support Services
