SUBJECT: Sewer Repair at 6450 Southcenter Blvd
Project No. 91340203
Bid Award
ISSUE
Award bid to Green River Construction, Inc. for the repair of the sanitary sewer line near 6450 Southcenter Blvd.
BACKGROUND
When City staff was cleaning and jetting the sewer line near the intersection of Southcenter Blvd and 65th Ave S, the
jetting head got stuck in the sewer line. Staff then pushed the jet head to the next manhole up stream of the clog and
removed the jet head from the hose and tried to pull the hose back to the Vactor truck. At that time, the hose became
stuck in the sewer line. Staff was unable to free the hose and it had to be cut and left in the manhole where the Vactor
truck was parked. Staff then tried to video the sewer line but was unable to see the blockage because it was under
water. It was determined that the only way the blockage could be cleared is to install a new manhole where the jet
hose is stuck. This proposed manhole location was determined by the counter on the Vactor truck hose reel.
After the installation of the proposed manhole, staff will be able to determine the exact location of the blockage in the
sewer line. A second excavation may be required once the exact location is found. The sewer line is located near fiber
optic lines and if it is determined that the sanitary sewer was damaged during the installation of the fiber optic lines, the
City will file a claim against the fiber company. If the sewer line is not repaired at this time and the pipe collapses, by-
pass pumping will be required so that sewer service can be maintained to the north hill of Tukwila.
DISCUSSION
Four firms from the MRSC Small Works Roster were asked to submit quotes for this project. King Construction and
Omega Contractors elected not to bid due to scheduling conflicts. The low quote came from Green River Construction
in the amount of $34,164.00, including sales tax, bonding, and insurance. Green River Construction has done
successful work for the City in the past.
