Will there be an evaluation committee to review the proposals and score them based on weights and multiple criteria?
Select the information you would like display.
Q (Chiller Specialist): The RFP states that the team is required to have a Mechanical Engineer (Chiller Specialist) with expertise in large centrifugal chillers (2,000-ton class) to review equipment, rigging plans, piping modifications, and sequencing. Is it expected that the chiller specialist provide design-level drawings and specifications for the project to show piping modifications and work required? If so, should a single set of draft drawings be provided for Owner review, followed by an IFC set of drawings? Only as-built drawings are noted as a requirement in the RFP.
A: See Addendum with answers provided to all questions.
Q (BAS Engineer): The RFP states a Building Automation System (“BAS”) Engineer is required to integrate new chillers into existing BAS and ensures seamless transitions between old and new equipment during phasing. If piping modifications are required, is it anticipated that any control devices (control valves, temperature transmitters, etc.) will need to be demolished and replaced? Please identify how many control devices may be required for replacement. Please provide information on the existing BAS (Siemens, JCI, etc.) and if contact information is available.
A: See Addendum with answers provided to all questions.
Q (Electrical Systems): The RFP states and Electrical Engineer is required to coordinate power shutdowns, switchgear tie-ins, starters/Variable Frequency Drive (VFD), and protection schemes, and ensures compliance with District codes and requirements. It's assumed the existing chillers are constant speed. Are they 480V or 4160V machines? If 480V, it's assumed unit mounted VFDs will be provided with the chiller. If 4160V, are there existing freestanding starters that will be removed to free up space for new freestanding chiller VFDs (VFDs added to the chiller per Addendum).
A: See Addendum with answers provided to all questions.
Q (Submittals and RFI): Submittals and RFIs are noted in the RFP. What is the expectation for quantity of submittals and minimum requirements? Is it anticipated that an engineer should provided specifications to identify minimum product requirements for Owner review and approval?
A: See Addendum with answers provided to all questions.
Q (Chiller Manufacturer): Trane is listed as the Basis of Design manufacturer in the RFP. Should any other manufacturers that offer duplex chillers in this capacity range (York, Daikin) be evaluated or allowed to bid?
A: See Addendum with answers provided to all questions.
Q (Existing Drawings): Are drawings (as-built floor plans and schematics, schedule sheets, control drawings, etc.) available, and can be provide to the successful contractor?
A: See Addendum with answers provided to all questions.
Q (Chiller Factory Testing): Is factory performance testing required for one, all, or any amount of the chillers?
A: See Addendum with answers provided to all questions.
Q (Performance Testing): Commissioning and "Performance Test" reports are noted in the RFP. It is understood that TAB and Cx are to be provided under this project. Is Field Performance Testing of the chillers required, or is factory testing sufficient (if factory testing is required)?
A: See Addendum with answers provided to all questions.
Q (Chiller Replacements): Two if the existing six chillers are to be replaced at a time. Is there a window where construction cannot occur because the building load exceeds the capacity four chillers (i.e. no construction May-September timeframe)? Are any rental / temporary chiller plans required for any part of construction?
A: See Addendum with answers provided to all questions.
Q (No subject): Is contractor to provide a new refrigerant monitoring system or reuse the existing? Is the current electrical power feed adequate for the new equipment? If the current electrical power feed is adequate for the new equipment, can it be reused? Is there any chance we could bring our rigging contractor back to the facility to be able to walk through the chiller room? This would be helpful to ensure we have a correct rigging plan for removal of old and installation of new chillers. We would like to be able to have them revisit the site this week if possible. Would it be possible for Events DC to provide mechanical, structural, and architectural drawings to assist with proposal preparation?
A: See Addendum with answers provided to all questions.
Q (2nd Site Visit Request): Can a second site visit please be arranged this Wednesday (3/25) at 8am in order to bring additional team members and subcontractors to view the chillers and cooling towers?
A: See Addendum with answers provided to all questions.
