The cost of these additional services is included in the overall project budget and staff is not asking for additional budget authority. BACKGROUND The City of Tukwila hired Shannon & Wilson to perform geotechnical evaluation services to the Justice Center and Public Works Shops sites in connection with the Tukwila Public Safety Plan. These services were to be done in two phases. Phase I was a preliminary geotechnical evaluation and Phase II was a more detailed "feasibility" geotechnical evaluation. The contract value for these initial services was $37,700. On March 26th, 2018, Amendment No.1 added extra mobilization costs in the amount of $1,000 bringing the contract value to $38,700 plus a contingency of $10,000 that has remained unused. On December 26th, 2018, Amendment No. 2 changed the duration of the contract, extending it to December 31, 2019. ANALYSIS Amendment No. 3 is to add additional geotechnical construction services at the Justice Center site, as well as extend the duration of their contract to December 31, 2020. These additional services will be broken down into three tasks: additional geotechnical recommendations for temporary shoring, construction document review, and construction observation. The expenditures associated with these tasks are anticipated and are included in the council approved project budget. FISCAL IMPACT Shannon & Wilson has provided a proposal of $31,080 to complete this scope of work. As there is an unused contingency of $10,000 from Amendment No. 1 available, we can subtract that amount from Amendment No. 3, making the proposed additional cost $21,080. The following table shows the Original Contract Amount, the previous amendments, Amendment No. 3 with the unused contingency subtracted and the new total. The amounts shown below are all within the approved project budgets and staff is not asking for additional budget authority.

Due to a cancelled committee meeting and extended agenda items on another, this item is coming directly to the Committee of the Whole for deliberation. The Council is being asked to consider this item at the March 25, 2019 C.O.W. meeting and authorize the Mayor to sign the contract at the Special meeting to follow that same night.
