Project will intercept flows that currently flow to Lift Station 10 which is near capacity. The Lift Station site is located just north of 196th Street SW on the west side of 56th Avenue W. The new force main will convey sewage from Lift Station 16 to an existing flow control structure just west of 68th Avenue W and 204th Street SW intersection.
Work this week included, from the week
starting May 16th:
Force
Main: The crew moved closer to demobilizing the project
by completing the grind and overlay for the air vacuum assemblies, scheduling
the grind and overlay for 68th Avenue, 202nd Street, and
196th Street, completing punch list items for Scriber Lake Road and
60th Avenue, and planning for the hydrostatic pressure test. They scheduled the remaining grind and
overlay, the exception is 56th Avenue, for Thursday and Friday, May
26th and 27th. 56th Avenue will be grind and
overlay just after the lift station is constructed.
At the force main discharge, which is at a flow control structure on
Edmonds Community College, Pivetta installed a blind flange with a valve to
regulate the amount of air and water that will be removed from the force main
as it is filled. The crew also grouted the gravity main into MH #1B on 56th
Avenue so that water wouldn’t penetrate the structure and flow into the wet
well.
Lift Station:The CMU installation continued through the
week. On Friday, Fairweather started the
outside brick veneer installation. The electrician and block-layers continued working closely together to
assure correct conduit paths were maintained.
This task required rebar and electrical inspections. Shinn received a final inspection on the force main that leaves the
metering vault and the connection of the ROW force main. The inspector allowed them to cover that
fitting. The site contractor continued
to complete the rough grade.The structural steel footings and building flashing were also
installed.
Next week starting May 23rd:
Force Main: The
crew will be preparing and conducting a hydrostatic pressure test of the force
main pipe and, weather permitting, a grind and overlay on 68th
Avenue, and 202nd and 196th Streets.
Lift Station: The
brick veneer for the building will continue.
