BACKGROUND In 2015, the City contracted with KPFF to design the relocation of the sanitary sewer force main required by BNSF as the railroad is adding a third set of tracks. DISCUSSION KPFF omitted from their original project scope the cathodic protection of the steel casing under the BNSF tracks that is required by the railroad. Additional time is also needed by the consultant to complete the plans and specifications for the relocation of the sanitary sewer force main due to the slow review of the documents by BNSF. FINANCIAL IMPACT The additional $7,876.20 required for the design of the cathodic protection system will be coming from the 2017 construction budget for the Fort Dent BNSF Sewer Relocation Project. 2015 Design Contract with KPFF 2017 Supplement Agreement No. 3 TOTAL Agreement Budget for 2017 $ 156,877.00 7,876.20 $164,753.20 $ 844 000.00 RECOMMENDATION Council is being asked to approve Supplemental Agreement No. 3 to Contract No. 15-054 with KPFF Consulting Engineering for the Fort Dent Park BNSF Sewer Relocation Project in the amount of $7,876.20 and consider this item on the Consent Agenda at the November 6, 2017 Regular Meeting.

GIS --� 2017 - 2022 Capital Improvement Program 82 57 58 SUPPLEMENTAL AGREEMENT NUMBER 3 to CONSULTANT AGREEMENT NUMBER 15-054 (c) This SUPPLEMENTAL AGREEMENT is entered into between the City of Tukwila, Washington, herein after referred to as "the City" and KPFF Consulting Engineers hereinafter referred to as "the Consultant", in consideration of to the mutual benefits, terms, and conditions hereinafter specified. The City desires to supplement the agreement entered into with the Consultant and executed on, March 18th, 2015 and identified as Agreement No. 15-064. All provisions in the basic agreement remain in effect except as expressly modified by this supplement. The changes to the agreement are described as follows: Cathodic Protection Background The purpose of this supplement is to prepare cathodic protection system design and specifications to the bid package for cathodic protection for the steel sleeve that carries the sewer force main under the BNSF rail tracks and extend the time for the consultant to complete the design package. SCOPE: ON SITE TESTING The testing will involve collecting in-situ soil resistivity at various depths at accessible locations to determine the electrically conductive of the soil. 1. Conduct on-site soils testing at locations of the casing crossing. Measure soil resistance at depths of 2.5, 5.0, 7.5, 10, and 15 -foot depths. This testing will involve passing a known current through appropriately installed soil pins and calculating resistance based upon voltage levels. This testing will not require excavation. 2. Collect two soil samples for laboratory analysis. The analysis will determine soil pH, chloride, and sulfate levels in order to classify corrosive characteristics. 3. Provide a report detailing the results of the testing along with recommendations for corrosion control strategies should the soil prove to be corrosive to steel materials. BUDGET/SCHEDULE The field testing with laboratory analysis results will be within ten days after soil collection. The cost for completing these tasks will be $2,130.23. SCOPE: COATINGS AND CATHODIC PROTECTION DESIGN 1. Based upon the results of the soil corrosivity analysis, provide a protective coating specification for the external surfaces of the sewer casing. pi -0(/,2 2 /1/(7.L Page 1 of 2 59 2. Provide a cathodic protection system design (drawings and specification) to supplement the protective coating. The design will provide corrosion control to locations of coating damage that may occur during installation, including at welded connections that may not be coated. It is anticipated that the system will utilize galvanic anodes which will not require external power. This installation of the coating and cathodic protection system will add an estimated 30 years to the useful life of the casing. 3. Provide a review of final project documents. 4. The design documents will be submitted in .pdf, .docx, and .dwg format. BUDGET/SCHEDULE The tasks associated with the design portion of this proposal are estimated to be $5,745.97. All work will be billed on a time and materials basis in accordance with the attached cost breakout. SCOPE: TIME FOR PROJECT COMPLETION The time for completion of the project is extended from December 31, 2017 to December 31, 2018. All other provisions of the contract shall remain in full force and effect. PAYMENT: SHALL BE AS FOLLOWS Payment for the work provided by the Consultant as part of this supplement shall be made for an additional $7,876.20. The total amount for the Consultant for this contract shall not exceed $164,753.20 without express written modification of the Agreement signed by the City.

PRESENTATIONS II. BUSINESS AGENDA A. Consultant Agreement: Water Reservoir and Pump Station Staff is seeking Council approval of a consultant agreement with Carollo Engineers in the amount of $47,005.00 for the Water Reservoir and Pump Station Feasibility Study. The Washington State Department of Health is requiring that the City provide additional water storage and this project will study the possibility of using Highline's Crestview Reservoir's extra capacity instead of building a new reservoir. MAJORITY APPROVAL. FORWARD TO NOVEMBER 6, 2017 REGULAR CONSENT AGENDA. B. Supplemental Amendment: Fort Dent Park BNSF Sewer Relocation *Staff is seeking Council approval of Supplemental Agreement No. 3 with KPFF Consulting Engineering in the amount of $7,876.20 for design of the Fort Dent Park BNSF Sewer Relocation Project. The original project scope omitted the cathodic protection of the steel casing under the BNSF tracks, which is required by the railroad. The amendment also covers additional time needed to complete plans and specifications for relocation of the sanitary sewer force main due to slow document review by BNSF. Funding for this amendment is available from the 2017 construction budget. MAJORITY APPROVAL. FORWARD TO NOVEMBER 6, 2017 REGULAR CONSENT AGENDA. There was consensus to consider the utility customer assistance programs for utilities as the next item of business. C. Customer Assistance for Utility Payments Staff updated the committee on possibilities to expand customer assistance for the City's water, sewer, and surface water utilities. Currently the City offers a 50% discount on utility bills to seniors (62+) and permanently disabled individuals making less than $32,000 annually. The 2016 Utilities Committee requested continuation of this policy discussion to include the cost of program expansion, described as follows: 1) Increasing the income limit to $34,000 or $35,000 would cost approximately $741.50 for each new sign-up. Staff does not believe this would assist a significant number of new people. 61
