BACKGROUND Washington State Department of Transportation (WSDOT) is preparing to overlay West Valley Highway between South 180th Street and 1-405. As part of the construction, WSDOT will correct roadway grading issues and overlay a portion of the City's Longacres Way South. The City's 2015 Annual Small Drainage Program also has a project to install a drainage system within the Longacres Way overlay project's parameters. The City was coordinating with WSDOT on this work, but was recently notified that the WSDOT project is approximately two months ahead of schedule and the overlay is now scheduled to be completed by the end of May. ANALYSIS To complete the drainage portion of the Longacres project within the limited construction window, staff broke out the Longacres Way South drainage work as a separate standalone project and solicited proposals using the MRSC roster. Eight proposals were received on April 6, 2015 and were checked and tabulated. Laser Underground and Earthworks, Inc. submitted the lowest cost proposal in the amount of $55,441.00. The engineer's estimate was $66,845.00. Laser Underground and Earthworks, Inc. has successfully completed drainage projects and their current references were satisfactory. The remaining projects in the 2015 Small Drainage Program will be advertised at a later date.
