INFORMATIONAL MEMORANDUM
Subject: Tukwila International Boulevard Phases II III Improvements
Project Nos. 95 -RWO3 95 -RW04, Contract 02 -108 and 02 -108b
Construction Management Adjustment Supplement No. 8
ISSUE
Approve Contract No. 02 -108 and 02 -108b, Supplement No. 8, with KPG Inc. for the Tukwila
International Blvd. Phases 11 III Street Improvement Project construction management and material
testing services.
BACKGROUND
The City contracted with KPG, Inc. to design the Tukwila International Blvd., Phase II Ill Project,
from So. 116th St. to So. 139th St. The construction contract was awarded to Gary Merlino
Construction on December 15, 2008. The construction management (CM) services for the project
were originally split between Tukwila staff, KPG Inc. and Harris Associates, Inc. Initially, KPG was
to provide design support and submittal reviews, materials testing and technical services through
subcontract relationships with select members of their design team. Harris was to provide the bulk of
the field inspection support, including specialty inspectors for some of our higher risk elements
(primarily the soldier pile walls along both sides of TIB). Shortly after starting construction it became
apparent that Harris had oversold their capacity for the field inspection role and that function had to
be picked up by other project staff. An employee of Krazan Associates (a sub consultant to KPG)
began filling dual roles as a transportation inspector and materials tester to support the hole created
by the lack of Harris staff. This created a need to increase KPG's CM support contract budget.
ANALYSIS
A recent analysis of the proposed Harris CM support contract shows a significant projected underrun
on the Harris contract (on the order of $500,000). This was caused by two primary factors. The first
is that the project appears to be well ahead of schedule and the inspection support is not anticipated
to run the original contract length. The second was due to Harris's inability to provide the support
personnel on the schedule proposed in the CM support contract and thus their lower level of
involvement under billed the project budget. We have been able to cover this shortfall in personnel
with some additional support by City staff and by shifting responsibilities for work within the project
team. This $181,903.40 Supplement No. 8 with KPG will be more than offset by the anticipated
$500,000.00 +1- savings from the Harris contract.
RECOMMENDATION
The Council is being asked to approve Contract 02 -108 and 02 -108b Supplement No, 8 with KPG,
Inc. for CM support for the Tukwila International Blvd Phase II III Project in the amount of
$181,903.40 and consider this item at the March 22, 2010 C.O.W. meeting and subsequent April 5,
2010 Regular meeting.
