ISSUE
Approve two change orders to the Utility Relocation Agreement between the City of Tukwila and Puget Sound Energy
(PSE).
BACKGROUND
In July of 2013 a Facility Relocation Agreement was executed between PSE and the City. This agreement defined the
roles and financial responsibilities for relocation of two underground vaults and two above ground switches in
association with the TUC Transit Center and Andover Park W Widening Projects. The two switches are on the
Westfield Southcenter Mall property and are therefore the financial responsibility of the City. The two underground
vaults straddled the right -of -way line along the Mall frontage and therefore the relocation costs to move them out from
the right -of -way are shared between Tukwila and PSE.
A cost estimate was included for the relocation work and the Facility Relocation Agreement capped Tukwila costs at
$738,400.00 (which included a 10% contingency), absent a mutually agreed upon change order or amendment.
DISCUSSION
PSE has completed relocating the northern vault along Andover Park W, referred to as V10, and the two above ground
switches. The relocation costs have exceeded the original cost estimate partially due to excessive dewatering of the
vaults, extensive traffic control, changes in field conditions, and additional property restoration. The additional property
restoration was a result of PSE construction occurring prior to the City's construction project, The PSE estimate
assumed that the utility relocation work would occur in conjunction with the City's project and that PSE's restoration
costs would be minimal. Relocation of the southern vault, known as V12, will be completed after the City's contractor,
Road Construction Northwest, removes the Firestone canopy structure.
FINANCIAL IMPACT
The total amount for Change Order No. 1 is $54,215.09, of which Tukwila is responsible for 71 % or $38,492.71
Change Order No. 2 is $37,422.09 and the City is responsible for 100 %. The total of the two change orders is
$91,637.18 and Tukwila's portion of the costs is $75,914.80. The change orders are currently within the total project
budget of $738,400, but the final PSE relocation costs for the second vault are not known at this time. There is a
potential overrun of the utility relocation budget of $55,733, if the cost estimate for the V12 work is accurate. Any cost
overruns exceeding the City's responsibility of $738,400 will be paid from the Project's construction contingency.
RECOMMENDATION
Council is being asked to approve Change Order Nos. 1 and 2 in the amount of $75,914.80 to Contract No. 13 -121
with PSE for the TUC Transit Center Utility Relocation and consider this item on the Consent Agenda at the February
18, 2014 Regular Meeting.
