Questions & Answers / Clarifications

This document provides clarifications and answers to questions submitted by potential bidders regarding the solicitation for mechanical room upgrades.

• Shop Drawings: Existing shop and construction drawings with equipment schedules for the mechanical room are not available to bidders.
• Boiler Rating: The 1,000,000 Btu/Hr boiler rating refers to the maximum output rating, not the minimum input/firing rate.
• Storage Tank Requirements: For the replacement storage tank, there is no material preference. The required working pressure is 150 PSI. The tank should be bare (not glass-lined). No ASME code requirements are specified.
• Tank Accessories: Tank insulation should use industry standard R-value. The relief valve should use industry standard PSI rating. Handhole and manway are not applicable.
• Boiler Efficiency: The Statement of Work will be revised to specify a minimum 97% Thermal Efficiency (ET) for the boilers, as AFUE is not applicable for the specified boiler size. This aligns with current Energy Conservation Standards for commercial packaged boilers.
• Boiler Communication: Boilers shall have BACnet capabilities, either BACnet IP or MS/TP.
• Warranty Requirements: To meet boiler manufacturer warranty requirements, the following components are required: Coalescing Air and Magnetic Dirt Separator, Hydraulic, Coalescing Air, and Magnetic Dirt Separator, Make-Up water Valve with RPZ Backflow Preventer, Bag or Bladder Type Expansion Tank, and Chemical Bypass Feeder.

These clarifications address specific technical requirements and will help bidders accurately prepare their proposals and understand the scope of work, particularly concerning boiler specifications, tank details, and necessary ancillary equipment for warranty compliance.

Questions & Answers / Clarifications

This document provides responses to vendor questions regarding the solicitation for boiler replacement and related system upgrades.

• Heating Pumps: The two additional 3 HP heating pumps identified during the site visit do not need to be replaced as part of this contract.
• Roof Patchwork: The roofing company with an existing warranty on the roof should perform patchwork related to stack removal. If no warranty exists, the awarded contractor will be responsible for this work.
• Heat Exchanger (Boiler 2): The heat exchanger in boiler number two is no longer in use and does not need to be incorporated into the new system.
• Control System Integration: Control Service Corporation will be utilized for the integration of controls for the new boilers, and the SOW has been revised to reflect this.
• Circulating Pump Function: The 1/6 HP circulating pump is used to heat the water storage tank, not for domestic hot water.
• Boiler Downtime: Boilers will not be taken down during the winter. Work cannot commence until after April 1, 2026, as specified in the revised SOW.
• 200 Gallon Tank Use: The 200-gallon tank is used for heating research water.
• Exhaust Vent Location: No preferred location for exhaust vents is specified. Bidders must ensure compliance with code standards regarding proximity to air intakes, operable doors, or windows.
• Roof Warranty: There is no warranty on the roof that will be impacted by repairs.

Several clarifications have led to revisions in the Statement of Work (SOW), particularly concerning the project timeline (post-April 1, 2026) and the inclusion of Control Service Corporation for control integration. Bidders should review the revised SOW for these updates.
