BACKGROUND The City commonly enters into a separate consultant contract to provide specialty inspection services, and soils/material engineering and testing during construction of utility pump stations, reservoirs, and other types of large utility facilities where the City does not have staff specializing in these areas. The construction of the Vineyard Avenue Corridor water booster pump station is a project that would benefit from specialty soils/material testing expertise. In accordance with project construction documents for the booster pump station, the facility will require continuous inspection of masonry wall construction, necessary welding, grout and concrete testing, and soils testing whenever this type of work is being performed. Staff is therefore recommending that an engineering consultant be retained to assure conformance with the approved plans and specifications for this project. CONSULTANT SELECTION PROCESS Staff solicited proposals from three construction inspection firms that provide individuals qualified in projects of this type. Proposals were received from BSK & Associates, ENGEO Incorporated and Berlogar Geotechnical Consultants. Staff determined that Berlogar Geotechnical Consultants was best suited to provide the necessary inspection services. Berlogar Geotechnical Consultants is the same firm that has provided the geotechnical investigation for the pump station design, in addition to providing similar inspection services for other City buildings. CONSULTANT FEE On February 6, 2007, Council approved the staff report awarding construction contracts for the Vineyard Avenue Booster Pump Station and Turnout No. 6 totaling $2,987,012. Included in this amount is $345,000 for construction management, soils analysis and specialty inspection. The addition of this $30,721 for the scope of consulting services to be undertaken by Berloger brings the total for these three services to $366,869. Staff recommends using a portion of the approved $345,000 project contingency to fund the $21,869 that must be budgeted for these services. Use of the contingency results in a contingency balance of $323,131 which is adequate for the project. It is in the City's best interest to have Berlogar Geotechnical Consultants work directly for the City and coordinate their inspections with those of the City's Construction Manager.
