Geotechnical Engineering Report Home Base Warehouse - Everett July 31,1997 NCA File No. 213497 Page 12 observe soil type or ground water conditions beneath the depths explored. We recommend that the contractor complete "potholes" in these areas to better evaluate soil and ground water conditions at the planned depths of construction before starting major earthwork. USE OF THIS REPORT l We have prepared this report for Mr. David Michaelis, and his agents, for use in planning and design of this project. The data and report should be provided to prospective contractors for their bidding and estimating purposes, but our report, conclusions, and interpretations should not be construed as a warranty of subsurface conditions. The scope of our work does not include services related to construction safety precautions, and our recommendations are not intended to direct the contractors' methods, techniques, sequences or procedures, except as specifically described in our report for consideration in design. There are possible variations in subsurface conditions. We recommend that project planning include contingencies in budget and schedule, should areas be found with conditions that vary from those described in this report. We should be retained to provide monitoring and consultation services during construction to confirm that the conditions encountered are consistent with those indicated by the explorations, to provide recommendations for design changes should the conditions revealed during the work differ from those anticipated, and to evaluate whether or not earthwork and foundation installation activities comply with the contract plans and specifications. Construction monitoring will be particularly important on this project because of the moisture sensitivity of the on -site till soils. Decisions regarding use of on -site materials, site grading and placement of fills will be in part dependent on the workability of the silty soil at the time of construction. Within the limitations of scope, schedule and budget for our services, we have strived to take care that our work has been completed in accordance with generally accepted practices followed in this area at the time this report was prepared. No other conditions, express or implied, should be understood. NELSON-COUVRETTE & ASSOCIATES, INC.
