RFI # RFI/Comment GSA Response

Will GSA be issuing As-Built Drawings in the near future of the existing Fire Alarm System? Also, the Fire Protection Asbuilt Drawings for reference? This information is necessary to see what may be existing to get the intent of what was originally installed to aid i the design and estimating of the replacement system.

Existing drawings to be provided but device locations and wall configurations accuracy is not guaranteed as these drawings are dated material; all contractors are encouraged to field verify anything questionable. Reminder: This is to be a100% new code compliant fire alarm system without regard to existing fire alarm system.

Will there be a sequence of how the demolition as well the new installation procedures be issued. Or will this be decided by the General Contractor overseeing the project?

General contractor to coordinate with GSA FPE to determine sequence to maintain existing fire alarm system while cutting in new system on selected floors.

Will there be afterhours work coordinated for extremely noisy work, core drilling, x-raying, etc.? Also for any work to be carried out when the tenants cannot vacate their area during normal business hours of the day if necessary to perform daily task of work?

Yes, some work will need to be scheduled outside of normal business hours.

How many power supplies will be required per floor?

Minimum one (1). Electrical calculations to determine if additional is needed.

How many SLC Loops will be required per floor?

Provide a minimum of two (2) Class B Signaling Line Circuits (SLC) per floor. The system must be designed and installed so that a single open, wire to wire short, or any other Class B impairment on an SLC does not affect more than 2,415 m2 (26,000 ft2) of gross floor area. The floor SLCs must be isolated from the SLC risers and network.

6 What Class of Fire Alarm System will be installed for 1.) the initiation circuit; 2.) the NAC circuit?

Class B; minimum of two distinct fire alarm audible notification appliance circuits and a minimum of two distinct visible notification appliance circuits must be provided on each floor.

Is there an existing Smoke Control System in place currently?

Stair Pressurization only.

8 If there is an existing Smoke Control in place, will it have to be revamped, too?

Stair pressurization is existing and will be operational by others prior to completion of the FACP Replacement Project.

8/19/2024 if there is no Smoke Control in place, will one be required?

Stair pressurization is existing and in place and the new fire alarm system will be requirted to be connected to this system for activation.

Will there be a Area of Refuge System required under this Design- Build Contract? Yes is there a Refrigerant Monitoring System in place for this Building.

Yes, display panel wall mounted in the mechanical room.

Can existing conduit installed in inaccessible location be used for the new system in order to minimize cutting, patching & painting?

Any such areas will be reviewed by the GSA FPE and if determined to be inaccessable or not feasible due to too much cutting or patching, then existing conduit can be allowed. Note, it is the intention of this project to install all new (RED) conduit except possibly in some select areas if proven to be inaccessable or not viable due to complexity of work involved to access.

13 1. Are existing conduits able to be reused when applicable?

Any such areas will be reviewed by the GSA FPE and if determined to be inaccessable or not feasible due to too much cutting or patching, then existing conduit can be allowed. Note, it is the intention of this project to install all new (RED) conduit except possibly in some select areas if proven to be inaccessable or not viable due to complexity of work involved to access.

2. Is a side by side installation expected, if so are we able to switch the devices over one floor at a time assuming fire alarm integrity is intact?

Yes, side by side and one floor at a time switchover acceptable.

15 3. Will you provide the annual Test and Inspection report? Yes 16 4. Will there be an opportunity for a second site walk through Yes

17 5. Will you provide updated site drawings?

No, only existing drawings to be provided but device locations and wall configurations accuracy is not guaranteed as these drawings are dated material; all contractors are encouraged to field verify anything questionable. Reminder: This is to be a100% new code compliant fire alarm system without regard to existing fire alarm system.

1. Can the existing raceways/pathways be used for the new installations?

No, but any area if determined to be inaccessable or not feasible due to too much cutting or patching, then existing conduit can be allowed. This is to be on a limited basis. Note, it is the intention of this project to install all new (RED) conduit except possibly in some select areas if proven to be inaccessable or not viable due to complexity of work involved to access. These areas will be reviewed by the GSA FPE with a decision provided.

2. Are there any existing Pre-Action or Suppression systems located within (or connected to) the premises?

Only sprinkler system with tamper switches and flow switches.

20 3. Can the existing door holders be re-used in all current locations? Yes

21 4. Will the premises have a two-way radio BDA system?

Awarded contractor will need to perform a test in compliance with IFC utilizing the local public safety radio system/frequency; BDA system, if needed, will be considered a contract modification to be completed by contractor.

5.Can you provide the “As Built” floor renovation FA drawings for the last 5 years?

Any existing drawings to be provided but device locations and wall configurations accuracy is not guaranteed as these drawings are dated material; all contractors are encouraged to field verify anything questionable. Reminder: This is to be a 100% new code compliant fire alarm system without regard to existing fire alarm system.

6. Can you please tell us if bid drawings reflect all the rooms ( conference ctrs, restrooms, kitchen, mail rooms, offices spaces, armory, unities…etc..) that being used or protected?

All drawings known to be available to GSA have been made available to all bidding contractors, however, there is no guarantee of accuracy of wall configurations and layout as many projects have occurred through the years on different floors. Most if not all floors do have a similar core layout.

7.Can we upload the program in its current format, from the existing Notifier Panel? And are these existing panels up to date with the latest revision of software?

This is to be a 100% new code compliant fire alarm system without regard to existing fire alarm system.

8.The Sequence of operations seems to be missing, can you provide the mandated/required sequence of operations for smoke control/ Smoke Evac?

The only smoke control for this building is stair pressurization. No atrium smoke control or smoke removal system.

9.Are the smoke fans, smoke dampers and associated equipment for the smoke control to be updated?

No, existing stair pressurization is to be activated by smoke detectors adjacent to stair doors.

1. As per RFI #1 on the attachment, will GSA provide a .dwg (i.e.

CAD or Background) for the building in its' entirety upon reward of contract?

GSA will provide any existing drawings but no guarantee any dwg files exist.

2. As per RFI #10 on the attachment, how many locations are to receive an Area of Rescue / Area of Rescue remote station? 15 total areas; floors 2 through 16.
