BACKGROUND On July 2, 2013, a Facility Relocation Agreement was executed between PSE and the City. This agreement defined the roles and financial responsibilities for the relocation of two underground vaults and two above-ground switches related to the Transit Center and Andover Park West Widening construction project. The two underground vaults straddled the right-of-way (ROW) line along the Southcenter Mall frontage; therefore, relocation costs to move the vaults out of the ROW are shared by PSE and Tukwila. The two switches are on Westfield Southcenter Mall property and are 100% the financial responsibility of the City. A cost estimate of $738,400.00 was included as part of this Facility Relocation Agreement. One underground vault (V10) and the two switches were then relocated by PSE in 2013. Change Order Nos. 1 and 2 were generated as a result of the extra work to relocate V10 and the two switches respectively. The two Change Orders were approved by City Council on February 18, 2014 for $75,914.80, bringing the total City responsibility to $814,314.80. DISCUSSION PSE has completed relocating the final remaining underground vault (V12) at the west Transit Center bus pull-out lane. The relocation cost has exceeded the original cost estimate due to the following: • The dewatering cost for vault relocation was significantly higher than the cost included in the original cost estimate. • PSE's wire crew had to reroute unknown service cables in vault V12. These unknown service cables were not documented in PSE's own record drawing; and the cable rerouting cost was not anticipated in the original cost estimate. • PSE's work crew had to extend their vault relocation work from two weeks (as estimated) to four weeks due to limited access space as the City's contractor was simultaneously constructing the walls at the west Transit Center. • Extended traffic control and unanticipated pedestrian safety measure costs for the additional two weeks. • PSE was required to replace an existing utility vault lid with a new anti-skid lid and some PSE manhole lids were also readjusted from existing locations to meet ADA requirements.

It was discovered during construction that the vault was partially under the roadway, necessitating the installation of a traffic bearing lid at additional cost. The bus pull-out was extended to avoid having the vault located directly under the curb and gutter. This re-design altered the grades for the vault, causing it to be installed deeper than originally proposed. The installation costs were increased due to additional subgrade excavation and other physical conflicts. • The original cost estimate in the Facility Relocation Agreement was based on 2012 PSE labor rates. The labor costs were increased since the actual work took place in 2014. FISCAL IMPACT The total amount of the cost increase to relocate Vault V12 was $147,451.00, in which PSE is responsible for 19% or $28,015.69 and the City is responsible for 81% or $119,435.31. The Transit Center Project construction contingency of $905,626.00 will be used to pay for PSE Change Order No. 3. As of today, nine change orders for $84,887.92 were executed for the Transit Center Project and there is a remaining $820,738.08 in construction contingency that is adequate to pay for PSE Change Order No. 3. RECOMMENDATION Council is being asked to approve PSE Change Order No. 3 in the amount of $119,435.31 to Contract No. 13-121 for the Tukwila Urban Center Transit Center Utility Relocation, and consider this item on the Consent Agenda at the December 1, 2014 Regular Meeting.

The Southern corners of the intersection will remain as is because SeaTac does not currently have plans or budget to make similar improvements in that section. Staff confirms that previous conversations have been held with SeaTac but agreed to approach the Public Works Director again to see if an agreement can be made. Additional research into options will be presented to Committee at a later date. INFORMATION ONLY. D. Tukwila Urban Center - Transit Center and Andover Park West Widening - PSE Facility Relocation Agreement Change Order No. 3 Staff is requesting Council approval of Change Order No. 3 in the amount of $119,435.31 to Contract No. 13 -121 for the Facility Relocation Agreement between the City and Puget Sound Energy. This agreement, executed on July 2, 2013, defined the roles and financial responsibilities for the relocation of two underground vaults and two - above - ground switches relating to the Transit Center and Andover Park West Widening project. Relocation costs for the vaults are shared by PSE and Tukwila and costs for the switches are the responsibility of the City. The original agreement included a cost estimate of $738,400.00, but two change orders approved in 2014 raised the City's cost to $814,314.80. PSE has completed relocation of the remaining vault and the cost has exceeded the original estimate due to several factors outlined in the informational memo. The total cost increase to relocate the final fault was $147,451.00, in which PSE is responsible for 19% and the City responsible for 81% equaling $119,435.31. Funds are available from the Transit Center Project construction contingency. MAJORITY APPROVAL. FORWARD TO DECEMBER 1, 2014 REGULAR CONSENT AGENDA. III. SCATBd Staff shared highlights from the October and November meetings. IV. MISCELLANEOUS Staff reported that the Transportation Improvement Board grant application for the 53rd Avenue South was unsuccessful. Per previous Council direction, a revised CIP sheet will be brought to Committee on December 8 that shows City funding for the design phase. Self- funding and completing the design will likely make the project more competitive to further construction grants. Councilmember Kruller mentioned a letter that was submitted by the Vietnamese Martyrs Parish expressing concern to the Mayor and Council about the possibility of property impacts as a result of the Green River System -Wide Improvement Framework efforts. Staff reported that the advisory group plans to issue a majority opinion in favor of not realigning the river, which would not impact the Parish property, and that this information has already been shared with Parish leadership. Meeting adjourned at 6:45 p.m. Next meeting: Monday, December 8, 2014 - 5:15 p.m. - Foster Conference Room Committee Chair Approval Minutes by LM, Reviewed by GL 79
