DATE: May 10, 2013
SUBJECT: 2013 Bridge Program — Fort Dent Bridge
Project No. 91310402, Contract 10- 022.13, Supplement No. 11
King County Discretionary Work Request # TK -009
ISSUE
Approve Supplement No. 11 (TK -009) with King County for the 2013 Bridge Program.
BACKGROUND
The City executed an Interlocal Agreement with King County in 2010, Contract No. 10 -022, under
which, upon request by the City, King County could perform certain services within the abilities of
the King County Road Services Division. This agreement renews automatically from year to year
unless written termination is agreed to by both parties.
For Supplement No. 11 to the contract, Tukwila has requested that King County provide bridge
repair services for Fort Dent Park Bridge over the Green River as part of the 2013 Bridge Repair
Program. The south approach on the Fort Dent Bridge has settled, causing increased traffic
impact to the bridge, as well as tripping hazards on the sidewalks. The proposed bridge repair will
correct the tripping hazards, as well as smooth the roadway approach, eliminating traffic impact
issues.
DISCUSSION
King County has provided an estimated cost of $40,355.00 to perform the work as part of the
2013 Annual Bridge Program. The estimated project costs are within the total $275,000 budget.
For 2013, we have obligated $34,800 for 2013 Bridge inspections, $23,000 for the Klickitat Bridge
and, with the Fort Dent Bridge at $45,355, the remaining balance is $171,845.00.

RECOMMENDATION
Approve Supplement No. 11 (Discretionary Work Request #TK -009) to Contract 10 -022 with King
County for the Fort Dent Bridge as part of the 2013 Bridge Repair Program in the amount of
$40,355.00 and consider this item on the Consent Agenda at the May 20, 2013 Regular Council
