On Wednesday, November 7, 2007 at 2:00 p.m, the Director of Engineering and General Services received seven (7) sealed bids for the "G" Street Sewer Pump Station Rehabilitation Project, in the City ofChu1a Vista, California (CIP No. SW-238)". ENVIRONMENTAL REVIEW The Environmental Review Coordinator has reviewed the proposed project for compliance with the California Environmental Quality Act (CEQA) and has determined that the project qualifies for a Class 2(c) categorical exemption pursuant to Section 15302, entitled Replacement or Reconstruction of the State CEQA Guidelines. Thus, no further environmental review is necessary. RECOMMENDATION Council adopt resolution accepting bids and awarding contract for the "G" Street Sewer Pump Station Rehabilitation Project in the City ofChu1a Vista, California (CIP No. SW-238)" project to Tamang Electric, Inc., in the amount of $477,420 and authorizing the Director of Public Works to issue change orders as necessary in an aggregate amount not to exceed $71,613. BOARDS/COMMISSION RECOMMENDATION Not applicable. 5-1 12/11/07, Item~ Page 2 of 4 DISCUSSION This project consists of various improvements to the existing City of Chula Vista "G" Street Sewer Pump Station. The work generally includes the removal and disposal of existing improvements, a new concrete slab supported by columns for the pump room, new pumps, motors, piping, valves and appurtenances, new asphalt concrete pavement, new emergency diesel generator, a section of new chain link fence with a sliding gate, lining of the existing wet well, new fiberglass grating, various building improvements including a new roof, doors, skylights and ventilation, and the construction of all appurtenances and other work as may be required to complete and render project workable. The items are to be constructed, finished and installed in a complete and workmanlike manner in accordance with the plans and specifications. The proj ect is located west of the Goodrich Company western property gate and east of Marina Parkway in the City of Chula Vista. The existing pump station was originally built in 1969. It has been modified several times over the years. The pump station facility conveys raw wastewater via a force main into City of San Diego Metro Interceptor. The project originated in 2005 as a full upgrade to current standards including emergency storage, new pumps, generator, and a new building at a cost of five million dollars. At that time more formal negotiations regarding the Bayfront development were taking place. As this project was being advertised as a design built proj ect and the vision for the Bayfront unfolded, staff realized the opportunity of ultimately eliminating this pump station. The Bayfront development was proposing a sewer line close to the location of the pump station that would eliminate the need for a pump station. At that point staff reanalyzed the benefit of such a large investment for a full upgrade to a temporary pump station and revised the project. The project before Council tonight is a limited upgrade to vital components of the station as described above. Because of the pump station's proximity to the bay and the age of its equipment these upgrades are necessary to curve the risk of a sewage spill for the next five to ten years. BID ACCEPTANCE On November 7, 2007, Engineering and General Services staff received and opened bids from seven (7) contractors as follows: CONTRACTOR BID AMOUNT 1. Tamang Electric, Inc. - Chino, CA $477,420.00 2. Cass Construction, Inc. - EI Cajon, CA $525,957.00 3. Southwest Civil Contracting, Inc. San Marcos, CA $526,700.00 4. DenBoer Engineering and Construction, Inc. - Thousand Palms, CA $527,000.00 5. Orion Construction Corp. - Vista, CA $547,300.00 6. Ahrens Corp San Diego, CA $599,360.00 7. NEWest Construction Co., Inc San Diego, CA $628,375.00 The apparent lowest bid of $477,420 submitted by Tamang Electric, Inc. is $7,420 or approximately 1.5% higher than the Engineer's estimate of $470,000. The Engineer's estimate was based on average prices for similar types of work completed during the last two years as provided by our consultant, Boyle Engineering Corp. On November 8th, 2007 a protest was file by Cass Construction, Inc. (the second lowest bidder) on the grounds that Tamang Electric Inc. 5-2 12/11/07, Item~ Page 3 of 4 had only listed one subcontractor. City specification call for any subcontractor that will perform work in excess of Y2 of I percent be listed. Because this project involves such variety of disciplines, the second lowest bidder requested that the City investigate this issue. City staff contacted Tamang Electric, Inc. and requested proof that they were able to perform all work necessary for this project. Tamang Electric, Inc. issued a letter assuring the City of their capabilities and included references for each discipline. References provided by the contractor have been reviewed and their work record found to be satisfactory. This Contractor has worked consistently with other City's standards and State standards. The Contractor is familiar with our City's Standards and is bound to comply with our requirements. The Contractor's license is in good standing and is current. Cass Construction, Inc. was informed of the City's findings and had no further issue. Approval of tonight's resolution will also authorize City staff to expend all available funds and increase the value of the contract as necessary due to unforeseen circumstances. Unforeseen circumstances may cause an increase in quantities beyond what was anticipated during the preparation of the project specifications. Due to the age of the surrounding area, unforeseen circumstances may occur during the removal of the existing improvements and the Contractor may find field conditions different from proposed improvement plans and specifications. As a result, a change order for additional labor and/or material may be required to complete the project. This is a typical situation with all underground projects built within this area. According to City Council Policy No. 574-01, if a change order exceeds the cumulative contract change order aggregate amount allowable to be approved by the Director of Public Works Operations, City Council approval is required. Under said City Council Policy, the amount would be $47,742. However, approval of tonight's resolution will increase the Director of Public Works Operations' authority to approve change orders as necessary up to the contingency amount of $71,613 (an increase of $23,871). If this money is not used during construction, the additional funds shall be returned to the original funding source - Sewer Facilities Replacement Fund. DISCLOSURE STATEMENT Attached is a copy of the Contractor's Disclosure Statement (Attachment 2). STAFF COSTS After the advertisement of this project as a Design-Build full upgrade to the pump station, additional staff time was necessary to reanalyze this project and to invest the appropriate amount of funds at this location given the forecasted development of the Bayfront area and the need for upgrading the old equipment. The rehabilitation of pump stations is not typical of the work the City performs, consequently, staff sought the expertise of an engineering firm to help resolve the complex issues associated with the design of the required improvement for this pump station project. Staff also provided technical support/oversight during the design phase and managed the project advertisementlbidding process. It is pertinent to note that Boyle Enginering is one of three firms that have an on-call contract with the City to support the Engineering and General Services Department for expertise and workload issues. DECISION MAKER CONFLICT Staff has reviewed the property holdings of the City Council and has found no property holdings within 500 feet of the boundaries of the properties which are the subject of this action. 5-3 12/11/07,IteID~ Page 4 of 4 FISCAL IMPACT At this time, staff recommends awarding the contract in the amount of $477,420 to accomplish the construction of the capital improvement project SW-238.
