Lewis County

On this project, we paved 32 miles of US 12 from near Packwood, across White Pass, to Rimrock. In addition, we paved the entire 2-mile length of SR 131 and 2.5 miles of SR 123, from the junction of US 12 to the Mount Rainier National Park Boundary. US 12 is a significant truck route connecting the agricultural region of the state to Interstate 5 and beyond to the Pacific ports. This work extends the life of the highway surface and provides motorists with a smoother ride.

Evaluation Criteria   Design: Contract Administration: Schedule: Cost: Engineer’s estimate: $5,999,682 Contractor’s bid amount:                      $6,690,350 Anticipated final payment to contractor: $6,492,929   Contractor’s bid amount was 11% above the engineer’s estimate; this was due to failure to consider the impacts caused by environmental constraints as well as the availability of the hot-mix-asphalt aggregate.

Construction Summary
We built the project according to the original design. For the most part, this project was a routine, rural paver, with the exception that the route passes through areas that are classified as suitable habitat for the Northern Spotted Owl.  This classification restricted our contractor from starting the majority of work until after July 15, and also restricted the working hours.  The contractor successfully scheduled the work operations and completed them within the contract time and tight environmental windows.

There was good teamwork between WSDOT and the contractor.  Each did their best to produce a good product with the least inconvenience to the traveling public as possible. 

Our contract specified 110 days to complete the project and it was completed 18.5 days early.  The final contractor payment is expected to be  three percent below the contractor’s bid amount.
