Boiler #6 Modernization Project

Request for Information / Sources Sought Notice Boiler #6 Modernization D/B The General Services Administration, Heating Operations and Transmission Division (HOTD), has the following requirement for Boiler #6 Modernization D/B. Location(s): GSA / HOTD 13th & C STS, SW Washington DC, 20407 THIS IS NOT A SOLICITATION ANNOUNCEMENT. THIS IS "SOURCES SOUGHT" REQUEST. ANY RESPONSE TO THIS RFI / SOURCES SOUGHT NOTICE WILL BE USED BY THE GOVERNMENT AS MARKET RESEARCH, FOR INFORMATIONAL PURPOSES AND TO MAKE APPROPRIATE ACQUISITION DECISIONS. - I. DESCRITPION OF WORK Boiler #6 (natural gas and #2 fuel oil) is rated at approximately 180,000 pounds/hour of saturated steam (250 psig/405F). The contractor shall upgrade the boiler as follows: - 1. Controls: Design, install and upgrade the existing Boiler #6 controls system to an ABB symphony/harmony distributed control system (or equivalent) compatible with the existing Infi90 DCS and this new controls system is able to be remotely operated from the central control room. Symphony Enterprise Management and Control System utilizing Harmony products including Harmony Control Units, Harmony Rack Controllers, Harmony Rack I/O, Harmony Modular Power Systems III, Harmony Control Network (C-Net) communication or equivalent controls system. This system will be factory tested. Demolish the existing control panel (see drawing and project report). Boiler controls also include the burner and igniter fire safety controls, positioning of the new flame safeguard scanners, since existing scanners' positioning results in frequent erroneous shutdowns. It shall be contractor's responsibility to determine the best location for the flame safeguard scanners. 250Hp FD and 450 Hp ID fans - change-out motors from 4160v to VFD compatible 480v and add Allen-Bradley VFDs or equivalent. Existing motors were designed for coal, #6 oil and shredded paper, and therefore, they may be oversized. The contractor shall determine the size of the new motors for a balanced draft furnace using natural gas and #2 fuel oil firing. - 2. Air heater: Demolish the existing Ljungstrom air-preheater and design and install an economizer. (see EBL's contract drawings and project report). - 3. Economizer: Design and install a feedwater economizer located in the area evacuated by the air pre-heater. Feedwater piping to economizer (inlet) - 6 inches. Economizer exterior shall have mineral wool insulation (4-inches) and aluminum lagging. The economizer should be a Kentube Engineered Products or equivalent. (see EBL's contract drawings and project report). Remove all air, water and steam piping associated with the old heater. - 4. Burners: The Contractor shall coordinate with the B&W Burner Company's engineer and carry out the added burner taps for better air flow distribution as recommended in the EBL contract drawings and project report. Replacing the existing burners with new requires too much EPA scrutiny, so utilization of existing burners with additional taps seems the best option for the Government, and therefore, the Contractor shall be required to carry out this option on behalf of the Government. - 5. Removal of the Electrostatic Precipitator (ESP): Demolish the ESP and design and install supports to structurally re-enforce the vacated area and re-roof the space. New roofing for the space occupied by the ESP shall be structurally re-enforced and re-roofed to match the existing roof. The Contractor shall be required to install and insulate the ductwork and breeching in place of the ESP. Note: It is the contractor's responsibility to return each of the components of this project back to the facilities existing conditions prior to the new construction, so the contractor should determine measurements before submitting bids. - A. Computer Aided Design (CAD): Drawings: All drawings developed by the Contractor shall be through computer based media (electronic data) and prepared in a format which can be used directly, without conversion, on AutoCad 2006 or later operating under Windows. Specifications: Specifications shall be developed through computer based media using specifications contained in these contract documents as a base. - B. Structural Requirements: The Contractor shall submit a proposed rigging plan and procedures for the installation of mechanical and electrical equipment. Calculations shall be submitted to verify the existing structure can safely support the proposed rigging and temporary construction loads. The calculations shall be signed and sealed by a Registered Structural Professional Engineer. The Contractor shall submit plans showing proposed locations of any cranes used on this project. The plans shall show the location of the cranes relative to the existing building and existing site conditions such as underground vaults which would impair the bearing value of the street pavement of sidewalk. The plans shall be signed and sealed by a Registered Structural Professional Engineer. Modifications to the building structure including cutting holes, adding or supporting mechanical and electrical equipment, pas, piping, ductwork, masonry walls or removal of structural members shall be included in the design documents and performed by a Registered Structural Engineer. - C. Quality Standards: All welders shall maintain up-to-date certifications. The welding certifications are to be submitted to the government before work begins. American Society of Mechanical Engineers Codes and American Welding Society Standards shall be followed. ASME Boiler and Pressure Vessel Codes (BPVC) ASME BPVC Section V (non-destructive testing) and ASME BPVC Section IX (welding & brazing qualifications) and AWS D1.1 (structural steel) shall be followed. Carbon Steel Pipe - ASTM A53 Pipe will be Schedule 80 heavy duty pipe. Adhere to ASME B31.1 Power Piping AWS D1.1 and ASME Section IX Hydrostatically test the new pipe per the latest edition of the IPC (1.5 times operating pressure for 2 hours) Adhere to the International Plumbing Code IPC) and the International Mechanical Code (IMC) All newly installed valves will be flanged and constructed to the ASME/ANSI B16.34 standards. API 600, API 598, API RP591, ASME B16.25, ASME B16.5, ASME B16.10 New valves will be stainless steel ASME 300 Class. Check valves will be Mueller Model 105MHT cast stainless steel globe body silent check valves or equivalent. The check valves will be ASTM A351-CF8M.
