CITY OF LAFAYETTE - WATER TREATMENT PLANT DECOMMISSIONING PROJECT REQUEST FOR CM/GC STATEMENT OF QUALIFICATIONS

Transcription

1 Introduction The City of Lafayette is intending to decommission the North Side Baseline Water Treatment facility. The North Side Baseline Water Treatment Plant (NSP) built in 1936 is no longer being utilized as part of the City s water treatment facilities and the South Side Baseline Water Treatment Plant (SSP) currently fulfills the City s water treatment requirements and operates independently. The NSP consists of a treatment plant building that houses a flocculation basin, 4 mixed media filters, a control room, a chemical storage room, and a piping gallery located below the control room. On the exterior, there are two rectangular sedimentation basins, a 130 diameter circular backwash recovery basin, a backwash well, and a subgrade clearwell. The NSP is hydraulically interconnected to the SSP with underground piping located in a tunnel under Baseline Road, referred to as the Utilidor. Decommissioning of the NSP will need to be done without compromising the operations of the SSP or the integrity of the Utilidor structure. There are several chemical and electrical connections between the two sides as well, and these will need to be carefully severed so as to ensure that there are no disruptions to the south side operations. Construction Management/General Contractor firms are invited to submit a Statement of Qualifications (SOQ) to the City of Lafayette for the Water Treatment Plant Decommissioning Project. Items required to be included in the Statement of Qualifications are outlined below in the CM/GC Criteria and CM/GC Statement of Qualifications sections. Three copies of the SOQ s are to be submitted by August 1, 2011 by 4:30 pm to the City of Lafayette Public Works Department, c/o Bradley Dallam, located at 1290 South Public Road, Lafayette, CO Project Approach The City of Lafayette is intending to use a Construction Manager/General Contractor (CM/GC) project delivery method for the Water Treatment Plant Decommissioning project. The CM/GC would play a lead role in developing the project scope and work packages resulting in a Guaranteed Maximum Price (GMP) presented to the City. The CM/GC would then furnish construction administration to perform the work, and oversee sub-contractors work, as described in the work packages. Pre-Qualification Sequence: City to obtain SOQ s from CM/GC s City to review all Statements of Qualifications City to establish a short list of top candidates and conduct interviews.

6 Project Overview The North Side Baseline Water Treatment Plant Decommissioning process has been outlined in the study of the same name, prepared by Arber Associates in The study will be utilized here to provide a synopsis of tasks required for the decommissioning project. The main tasks are: Hydraulic/Electrical/Chemical separation from the SSP Identification and removal of hazardous materials Protection of certain existing site features Salvaging of some parts and equipment Building demolition Physical disconnection of utility services New design elements These tasks are outlined in more detail below and are also discussed in the North Side Baseline Water Treatment Plant Decommissioning Study by Arber Associates. Hydraulic/Electrical/Chemical separation of the NSP from the SSP Abandon in place: 3-24 lines in Utilidor, isolate them via cut and cap at the north end of the Utilidor Remove chemical lines in Utilidor: Chlorine, Fluoride, Potassium Permanganate (KmnO 4 ), Alum, Polymer, Carbon, Sodium Silicate Remove piping at the NSP: orange zone line from NSB clearwell; 4 sludge line; 12 high service line from NSB clearwell, north of the isolation valve only Remove control wiring in Utilidor (power wiring for lights and sump pumps to remain intact) Construction Details of the disconnections or removals will be determined by the Project Team and provided in construction drawing or construction specification format. Identification and removal of hazardous materials Asbestos friable materials, including exterior caulking, adhesives, and fire door will need to be handled and removed by a licensed contractor and in accordance with federal regulations OSHA regulations are to be followed for worker requirements and removal An Air Pollution Emission Notice (APEN) will likely be required Lead-based paint found on metal I-beams, roof structures, doors and door jambs, sedimentation basin handrails RCRA metals: white wood ceiling joist in the Lab/Control room. RCRA materials are subject to federal hazardous waste disposal regulations and will require a RCRA certified environmental company for removal and disposal o Universal Waste and Hazardous Materials Survey includes materials that are governed by the Universal Waste Rule and must be removed and disposed of by a 6

7 certified company: Mercury found in thermostats; Flow control balance cells; Fluorescent, sodium, halogen lights; Electronic devices (circuit boards and fuses) containing lead solder; Fire Extinguishers; PCB s in light ballasts; Xcel Transformer (to be taken away by Xcel); Emergency exit signs are to be returned to manufacturer, or radioactive waste broker; Air Dryer (Freon refrigerant to be recycled); Chemical storage tank and chemical lines need to be checked for residuals prior to choosing proper disposal course Protection of existing features: Existing Trees: the site is bounded by Baseline Road to the south and the Goodhue Ditch in a half circle shape along the west, north, and east sides. There are several large cottonwood trees that share the Goodhue Ditch perimeter. These are located off of the property but the City will require that the root zones and branches be protected as much as possible during construction activities. Perimeter Fence: the existing perimeter fence will need to be protected in place and will serve as the limits of construction. However, if the final grading or drainage evaluation resulted in a proposed elevation change for the fence, the engineer and contractor would need to work with City staff and the Ditch company for approvals and permission to remove and replace the fence. Civil Defense Siren: located on the west side of the property at the fenceline, the civil defense siren will need to be protected in place and operational during construction activities Utilidor: Maintaining the Utilidor is a significant interest to the City. The Utilidor will be maintained to allow for access to the PRV located on the north side of Baseline Road and for any future potential water treatment facilities located on the north side of Baseline. Baseline Road and right-of-way: it is not the intention of this project to disrupt traffic along Baseline Road, or impact any of the utilities that may exist within the road right-of-way unless they are specifically identified to be included with the demolition for this project. Salvage: Some of the existing equipment from the NSP may be salvageable for resale or donation. A salvage schedule can be developed by the project team with input from City staff. Some salvageable items may be the filter control consoles, electric panels, piping, pipe fittings, control valves, pumps, chemical feed pumps, etc if they are deemed to be safe, operable and maintainable. Building Demolition: 7

8 Exterior: process basins, sub-grade clearwell, sedimentation basins. Vertical concrete structures are to be removed to a specified depth below finished grade (foundation slabs are not anticipated to be removed at this point in time) Interior: filter room, rapid mixing chamber, control room, chemical room, pipe gallery and pumps, equipment The building has undergone structural failure in several places. The building structure is comprised of 12 or 15 concrete walls, 6 or 8 concrete floor slabs, wooden partition wall framing, wood truss roof framing Some Utilidor components: o PVC piping on the side of the utilidor that conveyed treatment chemicals is to be removed o Conduits on ceiling of utilidor that housed control wires are to be removed. Other conduits that house electrical wires for lighting and sump pumps will be maintained. o The Utilidor structure itself and the three 24 lines will remain in place. The Utilidor will still be utilized by City staff to access the PRV on the north side of Baseline and the 3-24 waterlines will remain intact, but unused. Disconnection of utility services: The project team will need to work with Xcel Energy to disconnect the electric and gas services, and remove the existing transformer; and the City to disconnect or abandon the existing sewer service for the property. New Design: There are a few proposed design elements that will be required for this project and will be prepared in the form of construction drawings and/or construction specifications. These are as follows: Final Grading and Drainage Plan Drainage Analysis or report (if necessary to provide evidence that stormwater drainage will not adversely impact the SSP, the Goodhue Ditch or Baseline Road Stormwater Management Plan and Stormwater Discharge Permit for CDPHE permit requirements Utilidor North Entry from the surface on north side including hatch, new wall on west side and stairs Landscape plan may include: site signage or an historical plaque, new fencing, plantings and turf or seeding, and irrigation. 8
