SECTION B BACKGROUND The Berkeley County Water & Sanitation (BCWS) is the responsible agency for the operating and maintaining of all potable water, sanitary wastewater systems, and solid waste disposal systems owned by Berkeley County, South Carolina. The primary goal of BCWS is to provide clean safe drinking water, sanitary collection and disposal of wastewater and sanitary disposal of solid waste within Berkeley County, South Carolina. PLANNING DOCUMENTS: There are several master-planning documents, which have been developed and are routinely updated. All professional services performed for BCWS shall be in accordance with these documents as amended or revised. These documents may be reviewed during normal working hours (9:00 AM to 5:00 PM), Monday through Friday, by appointment at the Business Office at BCWS. Wastewater Facilities Master Plan 2002 2022 - Prepared by Davis & Floyd-July 1994 Standards for Potable Water System & Sanitary Sewer Systems Connecting to the Authority System Prepared by Berkeley County Water & Sanitation Authority Wastewater cmom Prepared by Engineering Resources Corporation February 2005 PROJECT SPECIFIC DOCUMENTS: PS 001 Modernization Prepared by Weston & Sampson November 2013 6
SECTION C SCOPE OF WORK The following outline scope of services is provided to assist the consultant in understanding the purpose of the project. This scope of services is not intended to limit the consultant in developing a project approach he believes is necessary to achieve the deliverable requested. The goal of this project is to take the recommendations of the existing preliminary engineering report and develop a set of plans and specifications for permitting, bidding and oversee the project through construction. Project Description Pump Station 001 is the largest pump station in our sewer system. The station was constructed with four (4) Flygt 248hp submersible pumps and is designed to transmit 19,300GPM with three pumps in operation. At startup each pump delivered 8,650GPM at 72 TDH. This station was placed into operation in 1994. The attached PER outlines changes in: Pumps (Operational Theory, Sizes and Quantity) Wet Well Architecture Electrical Systems Odor Control In order to meet the expectations of BCWS, the consultant should outline how the project will be approached and highlight key decision points within the project where past experience and expertise uniquely qualifies the consultant for the project. The work plan should include review points to insure BCWS divisions are kept fully informed and adequate opportunities are included for review and comments. The PER that has been completed includes a Technical Memorandum for each of the following areas and should be studied prior to providing a response: Odor & Corrosion Control Hydraulic Evaluation Electrical Evaluation Physical Model The release of hydrogen sulfide gas in the station has led significant degradation of the electrical components at the station. The current design of motor control centers with common buss bars are problematic for routine maintenance and extremely difficult for total replacement. BCWS has also experienced a total loss of the station when the transfer switch failed in the open position and power could not be supplied by the utility or standby generation. For these reasons, BCWS staff supports the construction of a new building away from the wet well with independent power feeds to each pump panel as 7
described in the PER. We are also interested in pursuing the idea of dividing the station in half from the electrical perspective. This division would create two electrical systems that can be completely isolated. A hydraulic model of the force main was developed with the PER. A number of issues were brought to light by the model and are discussed in the TM. The model did show that the existing pumps would not be very effective at conveying water as VFD s. Taking this a step further the small pump / large pump design was evaluated. Based on findings in the model this is the strategy that was chosen for how the future station will operate. A physical model was also developed to evaluate hydrogen sulfide release, air entrainment, and sediment buildup with the station. The TM discusses a number of modifications to the architecture of the station as well as the recommended location of the small pumps. The straightforward concept of limiting the drop of water into the well reduced air entrainment to the pumps and also reduced the release of hydrogen sulfide. To accomplish this the operating parameters of the small pumps will be to maintain an elevation in the wet well. The TM for odor control discussed a number of areas for limiting hydrogen sulfide release as well as a recommended scrubber for addressing what gases remained when the station is renovated. The final station design shall include provisions for a scrubber being added but, we will measure gas levels at the new station before moving forward with the installation of a scrubber. 8
SECTION D PROJECT SCHEDULE This is a critical station for the operation of the BCWS sewer system. BCWS did not prepare a proposed schedule for the development of the plans and specifications or permitting of the project. Included in the PER are proposed construction schedules for the different proposed phases of the project. Provide a comprehensive schedule in the proposal that includes design, review, permitting and construction. 9
SECTION E CONTENTS OF THE PROPOSAL PROPOSALS - The proposal must contain the following: 1) The submittal package shall contain five copies of the proposal. 2) The respondent s credentials outlining the firm s work experience with similar projects. Respondent should showcase the projects that best show the ability of the firm to meet the expectations of BCWS. Each example shall include a contact with the client that is familiar with the project and can serve as a reference. 3) The credentials and work experience of all key personnel who would be directly involved in the project. This should include the contribution of the individual to the projects presented by the firm as best examples of related work. 4) An organization chart showing the relative responsibilities of the project team proposed for the project. 5) A rate schedule including direct and indirect (overhead) labor cost covering all employees who would be involved with the project. 6) A detailed project approach shall be included. The project approach shall address the items outlined in the PER as well as other items critical to a successful project. 7) Accompanying the project approach should be a detailed schedule including intermediate review sessions with BCWS as discussed in Section D. 8) A non-binding fee proposal in EJCDC lump sum format based on the submitted project approach and submitted schedule.
