OTETRA TECH Exhibit "A" San Lorenzo Sewage Lift Station — Additional Services Request Page 2 Task No. 4: Estimate Truck/Equipment For Various Stages of Construction. Tetra Tech will provide estimate of the number and types of vehicles /equipment required for the various stages of construction. We are requesting a budget of $1,400 for this additional service. Task No. 5: Respond to Request for Additional Information. Tetra Tech will provide additional information as requested on construction methods, odor control system, etc. This is in addition to the normal question/answers included in Task No. 1. We are requesting a budget of $3,800 for this additional service. Task No. 6: Update Electrical Plans and Resubmit far Electrical Permit. Tetra Tech will update the electrical plans to incorporate any code changes and resubmit for electrical permit. The electrical plans were completed based on California Code 2007. The comments from the first electrical plan check comments were already taken care of. Therefore, the level of effort to perform the updates should be minimal. We are assuming the major change that may be required will be performing the Title 24 energy calculations. We are requesting a budget of $6,200 for this additional service. Task No. 7: Incorporate Mitigation Measures into Plans and Specifications. Tetra Tech will revise the project plans, specifications and cost estimate to incorporate any additional mitigation measures identified in the final EIR. We are requesting a budget of $1,500 for this additional service. Task No. 8: Preliminary Layout and Cost to Move Building. Tetra Tech was requested to prepare a preliminary layout and construction cost estimate to move the building out of the existing adjacent property. This work was performed to assist the City in the acquisition of the proposed easement. We are requesting our budget be increased by $4,000 to compensate us for this additional work. Task No. 9: Update Specifications due to Delay. The EIR process will be delaying the completion of the plans and specifications until at least January 2011. This is a two year delay from the date of the previously signed plans and specifications. Tetra Tech will need to confirm the manufacturer/ equipment specifications to make sure the equipment model/type specified is still available and appropriate. We are requesting a budget of $2,000 for this additional service. Task No. 10: Delay in Construction Phase Support. The original proposal assumed construction would be completed by June 2007. Our July 17`t', 2007 approved extra increased our budget for construction phase support assuming would be completed by December 2009. Based on the estimated schedule of completing the EIR by early 2011, we are estimating that construction of the project will not be completed until end of 2012. This additional three year delay will impact the assumed cost to perform the construction support services. Our current approved Construction Phase Support budget is $47,400 (original proposal in amount of $43,100 and additional $4,300 per July 17`h, 2007 approved extra). We are requesting a 12% increase in the construction phase support to compensate Tetra Tech for this three year delay, or an increase of $5,600. With this increase, our Construction Phase Support Budget will be $53,000.
