EXHIBIT A SCOPE OF SERVICES ENGINEERING SERVICES FOR THE CITY OF TUKWILA DESIGN OF THE MLK WATER MAIN REPLACEMENT PROJECT SCOPE OF SERVICES The following Scope of Services has been developed to assist the City of Tukwila (City) with the design and construction of the MLK Water Main Replacement Project. The following tasks under this Scope of Services has been prepared based on Carollo Engineers' (Consultant) current understanding of the proposed project, previous efforts by the Consultant team members on other water projects, and discussions with City staff. PROJECT BACKGROUND The City of Tukwila (City) is replacing approximately 800 feet of 12 -inch ductile iron water main along Martin Luther King Jr. Way South (MLK) from South Boeing Access Road to the Seattle City boundary. The dead-end water main serves customers and hydrants along MLK before turning west on South 104th Place. As such, water service will need to be maintained during construction. The overlaying roadway and sidewalks are concrete and in relatively good condition. Sound Transit's light rail runs adjacent to the water main on an elevated track. The City's Water System Plan has identified a goal to serve 1,500 gallons per minute fire flow from the completed water main. The water main currently operates at approximately 140 pounds per square inch (psi) pressure and the City would like to test this water main at 200 psi. Trenchless pipe replacement options is being sought to limit the need to repave/replace existing roads and sidewalks, minimize traffic disruptions during construction, and limit overall project costs.
