HomeMy WebLinkAbout9 Hydrogeologic Consulting Services Agenda Item # TRUCKEE DONNER Memorandum To: Board of Directors From: Ed Taylor Date: June 15, 2007 Subject: Proposals for Hydrogeologic Consulting Services 1. Why this matter is before the board: Board approval is required for expenditures in excess of$15,000. 2. History: The Board previously requested that a Request for Proposals be issued the next time that hydrogeologic consulting services were required. On May 2, 2007, a draft RFP for Hydrogeologic Consulting Services was presented to the Board. The Board then approved issuing the RFP. 3. New Information: Four proposals were received by the District. The four firms that submitted are: AquA Hydrogeologic Consulting. Reno, Nevada Farr West Engineering &Quad Knopf. Reno, Nevada Fugro West. Roseville, California Wood Rogers. Sacramento, California After reviewing the proposals, the firms were ranked based upon the following categories (1 = Best, 4=Worst): Size of Firm (Available Resources) 1. Wood Rogers 2. Fugro West 3. Farr West Engineering &Quad Knopf 4. AquA Hydrogeologic Consulting Overall Experience 1. AquA Hydrogeologic Consulting 2. Wood Rogers 3. Fugro West 4. Farr West Engineering &Quad Knopf Familiarity with TDPUD &Martis Valley Basin 1. AquA Hydrogeologic Consulting 2. Farr West Engineering &Quad Knopf 3. Wood Rogers 4. Fugro West Response to District Needs 1. AquA Hydrogeologic Consulting 1. Farr West Engineering &Quad Knopf 2. Fugro West 3. Wood Rogers After the above review as performed, the cost proposals were opened and reviewed. On an hourly basis, AquA and Farr West are about the same and are less expensive than the other two. These two firms are smaller in size and are likely to have much lower overhead costs than the other two companies. The hourly rates between Fugro West and Wood Rogers were comparable. After reviewing all of the information I believe that David Carlson and AquA Hydrogeologic Consulting would be the best firm to assist the District in drilling the new well and site determination for future wells. I believe that their familiarity with the drilling conditions in the local area sets them apart from the other firms. As part of the preparation of the Bidding Documents for the Fibreboard Well, staff and AquA will contact the well drillers in the California/Nevada area to review the specifications on the past few wells and determine how they could be improved. The District will create a Master Services Agreement with the selected consulting firm. Work to be performed by the consulting firm shall be defined by Task Orders under the Master Services Agreement. Should the hydrogeologic consulting services provided by the selected firm prove satisfactory, the District may extend the term of the Master Services Agreement for up to three years. For future years, the hourly rates given in the Cost Proposal may be adjusted by an amount not to exceed the increase in the Consumer Price Index (CPI) as published by the United States Department of Labor for the corresponding time period. 4. Recommendations: Authorize the Water Department to retain AquA Hydrogeologic Consulting to assist the District with construction bidding and construction of the Fibreboard Well. The contract would be based upon the hourly rates given in AquA's cost proposal with an amount not to exceed $110,000.

Fugro's Water Resources Group is concentrated in our Roseville, Oakland, San Luis Obispo, and Ventura offices. It is anticipated that our Roseville office will be serving most of the field needs for your projects, with the continuous backing of Water Resources staff in our other offices. Fugro has broad expertise in water resources management and development. We have conducted hundreds of individual well design and well field development investigations, •- hydrogeologic investigations, basin safe-yield investigations, aquifer storage and recovery projects, water quality evaluations, desalination project feasibility studies, and groundwater basin management studies. Fugro provides well siting, well design recommendations, preparation of well construction plans and specifications, construction observation, and production testing for municipal and private water wells. Fugro's extensive experience in hydrogeology and well design is critical to successful well production. Perforation placement, perforation slot size, gravel pack gradation, casing design and installation, and gravel packs and cement seal placements are custom designed for each well. Fugro engineers and hydrogeologists assist clients in evaluating contractor bids and managing well construction and testing. As the client representative, we oversee the well construction, documenting the "as-built" conditions, design the production testing program, make recommendations for the optimal well discharge rate, and pump settings. We test and ._ document well yield, specific capacity and pumping level variations, and collect samples for water quality analysis. Water level monitoring is accomplished using downhole pressure transducers connected to microprocessor data loggers, which Fugro maintains as part of its inventory of well testing equipment. Fugro has extensive experience in evaluating and determining the causes of diminished production or injection capacity in water wells. Assessments include specific capacity testing, water quality analysis, particulate filtering and analysis using electron-microscope analysis, video logging, and review of operational data.

The District has faced challenges in constructing its wells, including:hard drilling,high-cost projects, and contractor claims. Some of these challenges- '` for example,hard drilling conditions and lost circulation-are inherent in the District's geologic setting and cannot be avoided,and Wood Rodgers has the experience to help the District minimize the impacts of these challenges. However, some of the other problems the District has experienced,with high-cost projects and contractor claims,can be avoided with a targeted project approach that is based on advanced drilling engineering methods. }- Because of the approach used on past District well projects,the pool of qualified drillers who .- are willing to bid District well projects has decreased. Some drillers who are willing to bid have increased their prices to compensate for the foreseeable problems that will result from outdated project approaches. To obtain high-quality and cost-effective well projects,it is imperative for the District to reverse this trend so that the best drillers in the industry will bid District well jobs at competitive prices. Based on my 27 years of experience in drilling engineering,I am confident that the way to accomplish this is to design new well projects using sophisticated ,., methods to reduce the uncertainty for drillers,and to manage the projects proactively so that developing issues are dealt with before they become change orders or catastrophic problems. I believe that it is time for the District to consider an updated approach to well projects-one that will provide the highest quality and most cost-effective well possible. The attached proposal describes what the Wood Rodgers team brings to the table. We look forward to the opportunity to show the District how smoothly its well projects can run. If you have any questions,or would like to discuss our approach in more detail,please contact me at (916)341-7447. .. Sincerely, Lawrence H.

The report shall include data analysis and recommendations regarding the production potential of the well and sizing of well pump equipment. 4.3 SITING OF ADDITIONAL WATER SUPPLY WELLS The District's Water System Master Plan has identified the need for additional water supply wells as development occurs within the District's water service area. The District's RFP has described the services required for installation of additional wells under Task 5. This task is to commence at the request of the District as described below: Task 5—Assist in Siting of Additional Water Supply Wells Farr West is familiar with the hydrogeologic setting based on previous experience working in the Martis Valley Groundwater Basin. Kirk Swanson and David Westhoff contributed to the Martis Valley Groundwater Availability Study while working for Nimbus Engineers as well as contributed to reports while working for Hydro-Search Inc. Understanding volcanic processes is critical to siting wells in the Truckee area. Dr. Swanson of Farr West has the extensive knowledge and experience working within volcanic geologic settings. Dr. Swanson has studied and published papers on volcanic processes. Thin interbedded units within a sequence of volcanic rocks and local secondary fracture permeability within lava flows can account for most of the potential production within a volcanic rock sequence. In addition,understanding the relationships between arsenic occurrences in volcanic rock sequences is importance in regard to siting wells in the Truckee area. Since the production on the Truckee area is derived from volcanic and alluvial rock units understanding the interrelationship between volcanic processes and alluvial/fluvial processes required. Services provided under the Scope of Work will include: • Review of hydrologic studies (general geological, fault, volcanic and hydrogeological studies) • Review of well driller's reports • Review of other recent relevant information collected data by the District or others The Consultant then shall assist the District in the identification of potential future well sites. The familiarity that Farr West and Quad Knopf have with volcanic geology and the local geologic setting is crucial for the success for this task. RFP Hydrogeologic Consulting Services - 13 - Farr West Engineering Truckee Donner PUD May 24, 2007 4.4 QUALITY ASSURRANCE/QUALITY CONTROL Farr West's management principles include planning, implementation, checking and improvement. Quality assurance includes quality control, which comprises those actions related to the, collection of field data, verifying physical characteristics of construction materials and placement of construction materials. Members of the project team are well experienced in Quality Assurance/Quality Control procedures. The teams procedures for Quality Assurance and Quality Control have been developed working on highly regulated sites including Environmental Protection Agency Superfund sites and Department of Energy sites on the Nevada Test Site. Team members also have experience with Quality Control procedures on less regulated sites. Quality Assurance procedures can be divided into two categories regarding municipal well drilling and installation. The first category of quality assurance relates to the accurate collection of data during drilling and testing. The second aspect of quality assurance is related to materials and methods for constructing the municipal well. Technical Specifications created by Farr West include criteria to assure that Quality Control is adhered to by the drilling and pump contractors. Sample collection, under continuous chain of chain-of custody, and analysis will comply with regulated laboratory quality assurance protocol including performance audits, data validation and verification efforts. Quality Assurance (QA) includes activities that ensure that data collected are of adequate quality given the project objectives. Quality Assurance consists of two separate but interrelated activities: Quality Control (QC); and Quality Assessment. Quality control refers to the technical activities employed to ensure that the data collected are adequate given the project objectives to be tested. Quality Assessment activities are implemented to quantify the effectiveness of the quality control procedures. Some of the steps being taken to ensure that high quality data is collected include: • Implementation of Standard Operating Procedures for documenting and describing activities and materials; • Internal (project manager, i.e. Farr West) review of program's scientific, technical and construction processes; • External (alternate project manager, i.e. Quad Knopf) review of program's scientific, technical and construction processes. The steps have been effective it controlling quality assurance in a cost effective manner. RFP Hydrogeologic Consulting Services - 14- Farr West Engineering Truckee Donner PUD May 24,2007
