ISSUE
Award the bid for the retrofit construction of the Tukwila International Blvd (TIB) and 5144th Street Mid -block Crossing with
Rapid Flashing Rectangular beacons (RRFB) and ADA compliant curb ramps.
BACKGROUND
Phase 1 of the TIB improvements constructed two midblock crossings using overhead signs and in- roadway lighting. These in-
pavement systems were prone to failure and required frequent repairs to maintain operations. In 2014, the ADA Improvement
Project replaced the S 1501h St crossing with the Rapid Rectangular Flashing Beacon system.
In 2015, the City commissioned a pedestrian crossing evaluation by The Transpo Group to study the high levels of pedestrian
crossing activity near the Abu -Bakr Mosque, located at S 141s' St and TIB. Based on the study information, maintaining a TIB
crossing at the existing location between S 142nd St and S 1441h St and upgrading it to a RRFB signal was recommended.
In May 2016, three engineering firms were selected from the Municipal Research and Services Center (MRSC) Consultant
Roster and KPG Inc. was awarded the design contract for the project, which they completed in September 2016.
DISCUSSION
A call for bids was sent to the MRSC Small Works Roster and three bids were received on October 13 with Westwater
Construction Co. as the apparent low bidder at $88,300. The Engineer's estimate was $79,167. No errors were found in the
bid tabulation and a background check was conducted on Westwater Construction Co.
