INFORMATIONAL MEMORANDUM
TO Mayor Haggerton
Transportation Committee
FROM Public Works Director
DATE. November 8, 2010
SUBJECT Tukwila Urban Center Access (Klickitat) Proiect
Project No. 84 -RW19, Contract No. 05 -071
Supplemental Agreement No. 11
ISSUE
Additional design scope and budget in order to meet WSDOT requirements and minor utility design adjustment for the Klickitat/Southcenter
Urban Access Improvement Project.
BACKGROUND
The design of the Tukwila Urban Access Project halted at the 100% shelf -ready design in May of 2007. At the time it was shelved, there were
a number of outstanding issues requiring resolution before the project design efforts could resume Those issues included WSDOT
approvals, design of the buttonhook ramp, right of way (ROW) acquisition, property coordination and associated design efforts, construction
phasing and formation of the Local Improvement District.
Supplemental Agreements #8 and #9 were developed to complete the design based on the new WSDOT and Federal Highways
Administration (FHWA) requirements. Supplemental Agreement #10 was a simple time extension Even after execution of Supplemental
Agreement #9, WSDOT continued to place new requirements on this project beyond the scope of work developed After extensive
negotiations, WSDOT and FHWA have given the necessary approvals and permits allowing the project to go to ad, but with the understanding
that two late- emerging requirements would be completed concurrent with the ad period and early construction The two requirements are to
design and construct a monotube sign bridge on Southcenter Parkway between the Nordstrom signal and Klickitat Drive and provide Public
Interest Findings (PIF) for the project file for materials which are either sole source or have less than 3 brand names identified
Puget Sound Energy (PSE) and Qwest have a major shared utility duct bank on the east side of Southcenter Parkway, south of Strander
Boulevard, which is encased in concrete. Early coordination with PSE and Qwest was somewhat successful but as the project neared the ad
date of September 30, 2010, details on the utility duct bank were not provided to the design team in a timely manner The Plans,
Specifications and Estimate (PS &E) documents for the project identified the potential major utility conflicts Unfortunately there was
insufficient time to modify them prior to the September 30th ad date
DISCUSSION
Supplemental Agreement #11 includes design for the sign bridge on Southcenter Parkway and re- design for the storm drainage to avoid the
duct bank. Scope and budget is also included for the PIF's WSDOT will need to review and approve the sign bridge design but will not be
reviewing or approving the rest of the work. The budget reflects the anticipated level of WSDOT coordination Funding for Supplemental
Agreement #11 will come from the federal construction funds recently obligated The work will be issued as a change order to the contractor
Minimal impacts to the construction cost are anticipated

Task 22.4 Ductbank Preservation PS &E Revisions
Consultant shall revise the PS &E to avoid conflict with the PSE and Qwest duct banks and the
City -owned fiber optic line on Southcenter Parkway (Sta. 5 +00 to 8 +00). The Consultant shall
revise the PS &E to avoid the PSE duct bank at Strander Boulevard (Sta. 31 +90 to 33 +00). This
includes coordinating with the private utility companies, potholing and surveying at conflict
locations, updating the basemap, identifying the feasibility of redesigning elements to avoid
conflict with the duct banks, and revising the following design elements: drainage, roadway
grading, retaining wall, and associated specifications and estimate.
Once pothole data has been collected and analyzed, the Consultant shall analyze the PS &E
revisions assumed below for feasibility and cost effectiveness. Should the assumed PS &E
revisions not adequately address the utility conflicts, not be feasible or cost effective, work on
this scope item (22.4) will be stopped until the matter can be further discussed with the Agency.
Assumptions:
Potholing and survey at up to five (5) areas.
The base map survey will be revised to show the actual PSE and Qwest duct bank width.
The feasibility analysis is limited to identifying the most cost effective approach to avoid
conflict with the PSE duct banks and make recommendations to the City.
Coordination will continue with PSE and Qwest.
Design revisions are limited to the following:
o Roadway grading revise roadway profile of Doubletree entrance to relocate low
point of curb returns to allow for moving drainage structures 38 and 39a.
o Drainage move drainage structures 38 and 39a, add shallow inlets at structures
35 and 35a and relocate the CB Types 2's, move underdrain from Wall 4, move
structures 86, 87, 88 (stormwater vault), and 89.
