1. Six Year TIP Program. As is done every year, a TIP that lists all the projects that could be
available for grants, was proposed. A spreadsheet showed that this year's projects are very

similar to last ye , gh . '" i
two projects or otherwise changed. Bob explained the new Southcenter Parkway (S. 180 -S. C ty
Limits) includes the pr,o!aect called S 17St~ Street. ,T~he new projects include the Klickitat project,
S. 144t~ from TIB to 42 (formerly part of the 144 project); Southcenter B1vd (T.LB. - I-$);

2. Boeing Access Road Bridge Deck Improvement The bridge deck on BAR is badly worn,
and in places it's almost down to the rebar. The entire bridge needs to be replaced, but that is
unlikely to happen for several years. Because this project is not removing the sub-base, but only
the top layer of roadway, it will not move the project lower on the priority list it's on for grants.
The project will be done mosfly nights and weekends from early July-Labor Day. Joan asked
why there was only one bid. Bob said this is specialized work that few companies do. The City
of Sumner did not get any bids on its similar project. Bob said that Concrete Barfiir has worked
with Tukwila before, and is a very good company. The bid with contingency is very close to the
mount in the City budget. Recommend contract award to COW and Regular Meeting.
In past years the City used

one company to do all of its construction management, but in the last few years we've had staff
do it, or relied on the design company to do it. Such is the case with this project. The design
team, Sargent, is getting a sub, KBA, and together they will provide construction, se~ces for
$72,024. The committee questioned what was needed to approve this company. The City already
had a contract with Sargent, and the construction management would be a supplement to the
conjunct. The Committee members feli it should get Council approval because it is much bigger
than the original $25,700 Sargent contract. Recommend Mayor sign contract supplement
wlth Sargent for construction management services on BAR...
4. Wes~ Valley HighwayIStrander Intersection ~.mprovements 'The project to put an extra
turn lane on West Valley to Strander was completed by R.W. Scott Construction. There was one
change order, part of which involved replacing the traffic loops in the road. They were scraped
up when the resurfacing was being done, and had to be replaced. There were overruns due to
more roadway fili and asphalt, and to avoid some utility conflicts. The City also got a credit
because the company was allowed to put in PVC rather than steel conduit pipes. Recommend
contract acceptance and release of ret.inage to consent agenda of a Regular Meeting:
