INFORMATION NEEDED:
1. Please confirm that the responsibility to furnish and install the heat trace system is that of the mechanical contractor.
1. In review of the drawings and specification we identified a single heat trace panel that is to be installed in AHU-19 alcove that will serve all heat trace circuits.
1. The heat trace, providing freeze protection for the LPS & LPR will be industrial grade able to be exposed to maximum continuous temperature, power off, of 420°F.
1. Will the dedicated heat trace panel have alarms monitored by a NC alarm relay or by the BAS via BacNet protocol?
1. Will Submittal Exchange be a requirement on this project?
1. Is it possible to request a Second Site visit or if one is going to be offered?
1. What are the measurements of the Chilled Water Coils and locations of drain pans for AHU-19? This information is needed to size the UVC.
1. Will the UVC for AHU-19 be factory supplied and installed or will the M.C. be supplying and installing this?
1. Can the AISC certification requirement be waived for this project (for fabrication and install)?
10. Confirm project is tax exempt?
11. What is correct ICRA level to be followed during construction?
12. Has the entire project area been reviewed for potential ACM materials including ductwork?
13. Roofing:
a. What type of roof is existing including insulation currently installed?
b. Is any portion of the existing roof area which is to be worked on under warranty?
c. If under warranty is there a specific roofing contractor that is to be used due to the installation and manufacturer warranty?
14. Temporary partitions are to go to ceiling or deck above? If to deck provide floor to deck height?
15. Are sprinkler systems per Penthouse Fire Protection Plan able to remain out of commission for any extended timeframe.
Drain down and refilling on a daily basis will greatly restrict working time
16. Is there an existing fire pump and does this pump have capabilities for proposed modifications?
17. What are limitations for working on floors 2 thru 6 when working in public areas? Are we able to construct area enclosures to allow for extended work timeframes above ceilings or are we required to open and close daily?
18. What is expected for air balancing each floor? After each unit is worked on or a total floor once work is completed?
19. Antenna removal:
a. Provide complete existing antenna drawings including height and weights
b. Provide antenna / roof attachment details and extent of removal required?
20. Structural steel support system:
a. Provide confirmation that new structural steel pieces / components can temporarily placed on existing roof areas on dunnage prior to installation
b. Confirm if new steel is to be painted after installation? This is unclear
21. Please provide the name of the roofing contractor that holds the warranty for roof sections that are incorporated into this project. Please also provide the roof warranty expiration date if that date will occur during the duration of this contract.
22. Request the Government consider taking Electronic bids for this Solicitation.
23. The specifications talk about workstations and laptops. The drawing on page M0.14 show two future workstations on the riser it is our intention to bid the project without new laptops or workstations. Is our intention correct?
24. Controls graphics shown on drawing page M0.14 talks about various floor graphics and space temperature and associated setpoints. I can see penthouse floor graphics and the penthouse roof graphic but not the other floors. Is this your actual intent or are we missing information for all of the possible floor work?
25. Flow meter controls and sequence of operation page M0.10 shows hardware points in a table that I believe were meant to be integration points between the flow meter across BACnet MS/TP and the local DDC panel. Would you agree with this interpretation?
26. Heat Trace control panel page M0.10 shows hardware points in a table that I believe is inaccurate. Not sure how the provided table matches up with the requested points. I would believe the alarm activation for each circuit would all be digital inputs not analog. The enable/disable would be a binary output. The heating percentage is shown as a binary output and if we could receive a signal from the heat trace panel it should be an analog input. But I believe the heat trace panel can only send and receive digital signals. Would you agree with this interpretation?
27. On drawing MO.14 It states that the JACE is provided by the Systems Integrator. Would that not be the controls contractor or does the Hospital already have a Systems Integrator? If so where does their work start/stop?
