<br /> <br />ATTACHMENT “A” <br /> <br />INTRODUCTION <br /> <br />The project will consist of ADA improvements to the intersection of Evergreen <br />Way and 79th Pl. SE, including reconstruction of curb returns to provide ADA- <br />accessible facilities to current standards. In-house design for the civil and <br />intersection layout with Consultant signals design. Project delivery is design-bid- <br />build with construction to take place in 2023. This project is a result of a Service <br />Request received in December 2021, requesting upgrades to existing facilities. <br /> <br />Additional design phase services provided by the Consultant under Task Item 1, <br />4, 5, 7 & 9 consist of additional project management, additional signal design and <br />coordination, additional pre-ad ready design and coordination, preparation of pre- <br />ad ready plans, estimate, and specifications for submittals, additional plan <br />preparation, estimate, and specifications. Also, revisions based on comments as <br />requested by the City of Everett (City). <br /> <br />This Supplement Scope of Services also includes professional services to <br />provide construction phase engineering design support and construction <br />management services by the Consultant. The estimated number of working days <br />for the construction phase is 35 working days. <br /> <br />In the following, the additional scope of work is described in further detail. <br /> <br />Traffic Signal Design <br /> <br />A. Review the existing infrastructure and underground utilities maps and meet with <br />City of Everett staff to initiate the project. <br /> <br />B. Design a traffic signal system, including but not limited to relocation of junction <br />boxes, conduits, conductors, detectors, pedestrian crossing equipment (including <br />countdown signal heads and APS), and signal hardware. The expectation is that <br />the new traffic signal would be designed to be interconnected by existing fiber optic <br />cable to operate with the existing traffic signal at the intersection of Bruin Blvd and <br />Evergreen Way, and the north leg of Evergreen Way at SR 526, which is located <br />1020 feet to the south. The existing signal cabinet will remain. <br /> <br /> <br />ASSUMPTIONS: <br /> <br />• No traffic operational analysis and/or signal timing modifications. <br />• No civil, roadway, stormwater drainage analysis or design. <br />• No lighting analysis or design.
