Project Completion: Andover Park East - Water and Sewer Replacement Staff is seeking Council approval of contract completion and release of retainage to Titan Earthwork LLC in the amount of $3,887,443,56 for the Andover Park East Water and Sewer Replacement Project. This project provided new and upgraded water and sewer lines on APE between Strander Boulevard and Tukwila Parkway. Thirteen change orders were executed, primarily due to unforeseen subsurface conditions. A final settlement change order was negotiated for significantly less than what the contractor had initially submitted. The original contract was $3,504,684.14. UNANIMOUS APPROVAL. FORWARD TO MAY 6, 2019 REGULAR CONSENT AGENDA. B. Project Completion: 2018 Central Business District Sanitary Sewer Rehabilitation Staff is seeking Council approval of contract completion and release of retainage to the Michels Corporation in the amount of $411,460.27 for the 2018 Central Business District Sanitary Sewer Rehabilitation Project. This project installed approximately 3,660 lineal feet of pipe within the right-of-way and private easements. The original contract was $449,633.25. Underruns were mainly due to work deleted due to various conflicts that would not allow the relining at this time. UNANIMOUS APPROVAL. FORWARD TO MAY 6, 2019 REGULAR CONSENT AGENDA. C. Tukwila Infrastructure Design and Construction Standards Update Staff updated the Committee on the effort to update the Tukwila Infrastructure Design and Construction Standards, which have not been revised since 2009 and are intended to ensure consistent design and construction requirements and adherence to the Comprehensive Plan. They establish minimum criteria and specifications for both public and private construction projects and utility and street improvements. The 2019 revisions integrate WSDOT standards, low impact development principles, and were thoroughly reviewed by a staff committee and the City Engineer. Chair Idan asked if the revised standards would address the issue of inconsist connections with adjacent city streets as well as utility patching. Staff noted that utility work is performed by third parties outside of the city's inspection process. Councilmember Kruller asked if the standards include a street moratorium and staff replied that they do. All agreed that Council and staff collaboration on messaging and enforcing the City's standards will be helpful. Staff intends to review every two years and the Council will be kept informed. DISCUSSION ONLY.
