Exhibit A <br />SCOPE OF WORK <br />Description of Work <br />OPL will develop a design and plan to relocate its 14 -inch and 12 -inch petroleum pipelines in <br />interference with the Strander Boulevard Expansion Project in Tukwila, WA. This relocation <br />will accommodate the CITY's expansion of Strander Boulevard. As a result OPL's 12 -inch <br />and 14 -inch pipelines are impacted and will need to be relocated. <br />Under this Agreement, OPL will perform the following preliminary engineering design work <br />associated with the modification or relocation of its facilities. <br />Project Management <br />• Organize and develop work plan and advance design development. <br />• Provide guidance on private property coordination and legal review of any easement, <br />and coordinate with CITY on replacement easements and/or reciprocal conveyances. <br />• Procurement of engineering, surveying, and construction contractors. <br />• Track right of way document development. <br />• Coordinate with the CITY on the design and construction methods of the proposed <br />relocation so the CITY can proceed with the permitting. <br />Potholing/Soil Borings <br />• Pothole elevation of 12" and 14" pipelines upstream/upland tie-in location. <br />• Probe/confirm elevation of 20" pipeline downstream tie-in location. <br />• If sufficient subsurface soil and groundwater information is not available, complete <br />soil borings as necessary. <br />Survey Contractor <br />• Update topographic gaps from CITY -provided CADD and mapping information. <br />• Modify data for design development. <br />• Survey location of items during design phase engineering. <br />Modeling <br />• From updated field investigation, model proposed alignment for design development. <br />Design <br />• Design pipe relocation, bends, and length of pipe. <br />• Prepare right of way plan sheets. <br />• Identify laydown area and ingress and egress areas. <br />• Coordinate with mechanical contractor on constructability issues. <br />• Prepare plan view and profile of pipe relocation. <br />• Prepare contract specifications. <br />Geotechnical <br />• Review, evaluate, analyze, and plan for site geotechnical conditions that may impact <br />construction of the petroleum pipeline relocations. <br />10 <br />
