(RH2). BACKGROUND RH2 is the consultant for the 2016 CBD Sanitary Sewer Rehabilitation Project with Contract No.16-054. The consultant is designing the CBD Sanitary Sewer Rehabilitation Program for repair and relining of the remaining sanitary sewer pipe in the CBD (Commercial Business District). DISCUSSION This Supplemental Agreement will revise the construction documents to include the use of ultraviolet (UV) cured in place pipe lining (CIPP) as an option to steam cured felt liner. The use of UV CIPP liner will increase the number of contractors that do CIPP pipe relining and this may result in better bid pricing. The time for the consultant to complete the project will be extended to January 31, 2018. The original contract and Supplemental Agreement No. 1 (time only) and No. 2 were under $40,000, but with Supplemental Agreement No. 3, the total contract will now be $41,382.28 and requires Council approval. FINANCIAL IMPACT The 2017 design budget for the CBD Sanitary Sewer Rehabilitation Project is $45,000.00 Agreement Budget for 2017 2016 CBD Sanitary Sewer Rehabilitation $ 31,386.35 $45,000.00 2017 Supplemental Agreement No. 2 5,006.50 2017 Supplemental Agreement No. 3 4,989.43 TOTAL $ 41.382.28 $ 45,000.00 RECOMMENDATION Council is being asked to approve Supplemental Agreement No. 3 to Contract No. 16-054 with RH2 Engineering, Inc. for the CBD Sanitary Sewer Rehabilitation Project in the amount of $4,989.43 and consider this item on the Consent Agenda at the October 16, 2017 Regular Meeting.

IMPACT: COMMENT: The asbestos concrete pipe in the CBD (commercial business district) is approximately 45 years old and becoming soft. Slip lining the pipe will reinforce the strength with little impact to roadways and minimal excavation. If the pipe collapses, the street will have to be excavated and the cost of the repairs will be significant. In the last five years we have had four major pipe failures on Andover Park West and Andover Park East. In 2014 and 2015, over 10,500 feet of asbestos sanitary sewer pipe were relined. In 2016 through 2018, 20,000 feet of asbestos sewer is scheduled to be relined. Reduced maintenance and repair costs. A Public Works Trust Fund loan was successfully obtained in 2012 for $750k.

The City desires to supplement the agreement entered into with the Consultant and executed on, May 2, 2016 and identified as Agreement No. 16-054. 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: Background The purpose of this supplement is to add specifications to the bid package to allow for ultraviolet (UV) cured -in-place pipe (CIPP) to be installed. In the past seven (7) months, contractors with experience in the installation of UV CIPP have begun pursuing sewer pipeline restoration projects in Washington and Oregon. This is advantageous for the City because contractors that install the traditional felt CIPP have had an abundance of work in 2017. This has reduced competition recently, which increases costs and has delayed completion of work for some northwest agencies. Competition will be increased and more bids will be received if the City allows UV CIPP in addition to traditional felt CIPP methods to be bid. Below are the tasks necessary to modify the existing bid package to allow UV CIPP on this project. Task 1 — Technical Specifications for UV CIPP Objective: Modify existing bidding documents and technical specifications to allow contractors using UV CIPP to bid the project. Approach: 1.1. Perform structural calculations to size UV -cured liner thickness for soil and traffic loadings. UV CIPP has greater strength than felt CIPP and can be installed in thinner layers to accomplish the same level of structural integrity. 1.2. Add text to the Technical Specifications describing the required physical characteristics, codes, special installation methods, and other applicable items for the UV CIPP. 1.3. Edit bid schedule and pay descriptions to accommodate for traditional felt and UV CIPP. RH2 Deliverables: • Modifications to the Technical Specifications, bid schedule, and pay descriptions. 1. Time for Performance, the completion date of the work shall be January 31, 2018. (w: Projects/04sw08/Supplmental Agreement 9 APS) 49 ORIGINAL PAGE NO 2- OF PAGES 2. Payment, shall be as follows: o Payment for the work provided by the Consultant as part of this supplement shall be made for an additional $4,989.43. The total amount for the Consultant for this contract shall not exceed $41,382.28 without express written modification of the Agreement signed by the City.
