EXHIBIT A <br /> 7400 BLOCK LOWELL-LARIMER ROAD STABILIZATION <br /> CONTRACT AMENDMENT NO. 1 <br /> GEOENGINEERS, INC. <br /> GEOENGINEERS FILE NO. 0661-113-00 <br /> PROJECT SCOPE <br /> Task 100-Additional Services During Design <br /> GeoEngineers scope of additional geotechnical services during design includes the following: <br /> 1. Additional on-site time associated with the City potholing to locate the sewer force main during our site visit <br /> for drilling. <br /> 2. The first drilling subcontractor was unable to advance the borings through the very thick asphalt over <br /> concrete section. Therefore, a second drilling subcontractor with larger equipment was hired to complete <br /> the borings. Additional expenses were incurred because of standby time for the first drilling subcontractor <br /> and mobilization and drilling necessary using larger equipment by the second drilling subcontractor. <br /> 3. Additional on-site meetings with City and subcontractors. <br /> 4. Meeting with City to discuss project at City of Everett office. <br /> 5. Additional analyses for various alternatives, including a fill berm design alternative as requested by the City. <br /> 6. Laboratory testing of dredge sand. <br /> 7. Developing preliminary quantities/costs for fill berm and drilled shaft alternatives. <br /> 8. Issuing a revised draft report for review by City, which will include a fill berm alternative. We plan to issue <br /> our final report within 1 week after receiving review comments. <br /> 9. Consultation through the design phase of the project. <br /> Task 200 -Construction Observation Services <br /> GeoEngineers scope of construction observation services is based on our experience and an estimated number <br /> of part time site visits. We understand that the City anticipates the work will be completed in 4 to 6 weeks. <br /> Based on our discussions with the City,we have assumed that part-time observation for geotechnical activities <br /> will be required. <br /> The purpose of our geotechnical construction observation services will be: (1)to provide sufficient observation, <br /> consultation,and testing to evaluate if the work is being completed in general accordance with the intent of the <br /> project and our recommendations; (2) to provide engineering consultation and recommendations for design <br /> changes during construction, as necessary. <br />
