In addition, nearly all of the personnel assigned to the project performing design work are registered engineers in the State of California. The other proposals appear to have registered personnel engaged only in the supervisory phases of the project. A review of the fee proposal showed that while Krieger & Stewart does have an apparent higher cost, the reasons for this was determined to be due to the following factors: 1. The proposal submitted by Krieger and Stewart was the most comprehensive and included several tasks that were not included by the other vendors. According to discussions with Krieger and Stewart, these task elements were included to avoid possible change orders later in the project. 2. Krieger & Stewart allocated more time to the preparation and submission of environmental documents. Tasks such as biological, cultural and soil testing may need to be conducted and were not included in the proposals by the other vendors, thus resulting in an apparent lower cost. 3. Krieger & Stewart allocated significantly more time for on-site inspection of the drilling process and the collection and analysis of drilling samples. This was the greatest contributor to the higher cost of their proposal. By performing a detailed analysis of the material removed during drilling rather than depending on the drilling contractor to provide the data, the well design can be optimized for water production and quality. Once the well is designed and constructed, very few changes can be made. Inspection of the drilling process is the most crucial part of the well construction process. 4. The plans and specifications produced by Krieger & Stewart are typically very comprehensive. Krieger & Stewart has an excellent track record for minimizing change orders and controlling costs for well design and construction projects. In addition, the actual average hourly rate in the Krieger & Stewart proposal is less than the other two proposals that were evaluated. Section 3.08.070(f) of the Colton Municipal Code states that contracts for professional services shall be awarded to the contractor who will best serve the interests of the City, taking into account the demonstrated competence, professional qualifications and suitability for the project in general. Staff understands the apparent differences in cost between the proposals. However, these wells are anticipated to be in service for over 50 years. Proper design and construction of these wells is essential to the City providing adequate water supply at the most reasonable cost. A small reduction in capacity or water quality due to poor design could result in hundreds of thousands of dollars in costs over the life of the well. Thus, staff believes that Krieger & Stewart will be able to provide the best product at the most reasonable cost by maintaining schedule, minimizing change orders and maximizing water production. FINANCIAL IMPACT: Sufficient funds are available in Capital Improvement Account, Number 521-8100-8105-3890- 0000-000. ENVIRONMENTAL IMPACT: It is anticipated that the project can be performed under a mitigated negative declaration. An initial study will be performed upon award of this contract.
