MATSSC Security Project Pre-Bid Q&A Drawing 3/A-107 references a section detail: 8/A-503, however there no drawing #8 on that page. Could it be clarified where we might find this detail section?

Answer: The reference to detail 8/A-503 should have been removed from 3/A-107. The detail was removed from the original set as it is a detail for the waterproofing work at the auditorium that was removed from the project scope in our last revisions.

Do the architects have a specific product in mind for the roughly 12” terrazzo precast base under the artwork to avoid a 1/16-1/8” horizontal gap?

Can the location of the main supply of the current sprinkler system be confirmed?

Answer The first floor isolation valves isolate the east half and the west half respectively and are in the 1st floor SW and SE shaftways.

Can the GSA issue the existing sprinkler drawings?

Answer: We do not have a complete set of sprinkler drawings, as these are usually field drawn. If the question is more specific, I may be able to help.

Several of the plans have a scale shown as 1/1” + 1’-0”, should this be 1/16” = 1 FT?

Answer: The scale question appears to be a typo, however without knowing which sheet, I can’t answer if it should be 1/16”=1 FT or another scale.

Reference to Dwg. EL-102, note 1, where is panel HS- L located?

Answer: ED103 – ELECT. BASEMENT PLAN POST #6 DEMOLITION – the scale should read 1/8” = 1’-0” not 1/16” = 1’-0” On drawing EL-102, Panel HS-L is miss noted, it should be panel H-SL and this can be found on 3/EL104 and 3/EP103.

On Drawing QY 707 24

On the door chart, the column Labeled “Function Code” has (see note 2). Doors 2NW-12.1 and 2SW-4.1 also list (see note 2). Should this note be omitted from the top of the column? The note causes conflict when applied to all doors.

Answer: After reviewing the Drawing QY 707 24, it is apparent that “See Note 2” should be removed from the top of the column under where it is labeled “Function Code”.

Page 260533-9 item 3.1 B 4 permits ENT (plastic ) and PVC schedule 40 conduit in the ceilings, Is this permissible?

“Concealed in ceilings and interior walls and partitions: EMT ENT or RNC, Type EPC-40-PVC”

Is all the piping on MH-401 new piping? All lines are in bold and none say “existing pipe”. Also some line sizes are missing

Answer: See attached marked up drawing.

On drawing AP.1.01 there is no notation about the low protective metal rail along the floor in front of the mural. If this protective assembly is to be constructed as drawn, this railing must be removed. Is it the intention to have this railing removed or the assembly build around it? If it is to be removed, is that in the Art Protection Scope of Work?

Answer: The existing protective metal railing would not be required during the phase 1 artwork protection as the artwork would be protected via the plywood wall as drawn. We are not specifying if the existing railing needs to be removed or built around. The offeror should determine this as part of their means and methods. Any work performed that close to the artwork shall be closely supervised by the fine arts professional if not directly performed by this person.

During Phase 1, the Fine Arts Conservator is required to monitor the artwork the entire time the repairs to the floor and ceiling take place. Is there an estimate for how long this work will require?

Answer: The time to complete the work that requires the Phase 1 protection of the artwork will depend on the offerors means and methods for completing the project therefore we can not provide an estimated duration for this need.

Would it be possible to obtain the name and contact information for the Contractor that maintains or installed the sprinkler system referenced in the Unit Prices?

Answer: The SSA does not employ a lawn sprinkler contractor they just have the building maintenance contractor operate and maintain it. The contractor should seek out a lawn sprinkler contractor for any repairs required to this system as a result of this project.

See Spec Sections:

Question 2.

The interconnection drawing, QY-601-20, shows a redundant rack in Detail One. This is correct.

The riser shows a redundant VMS only, as well as the RTLS server and a single Access System Server. Please refer to detail One on QY-601-20.

Specifications do not address redundancy.

Can you please clarify the hardware/software redundancy requirements?

Answer: Contractor shall provide a complete redundant system. The system was originally designed as a fault tolerant system, preventing mainly from a power loss or communication failure for a short duration. The system was later changed to a redundant system per GSA/SSA comments to mitigate equipment failure. The total Redundant Security IT Rack shall consist of completely identical hardware and software equipment as the Main Security IT Rack, including but not limited to; cable management equipment, network switch, comm server, Access Control Server, Nice Server, monitor & KVM switch, UPS Battery Backup, and video storage units.

Terrazzo Work:

How long can the corridors be blocked to pedestrian traffic during the placing of terrazzo? Each section of the terrazzo work will require at least 5 continuous days of NO Traffic for prep, pouring and polishing the terrazzo.

Will we be able to perform the epoxy terrazzo work during regular working hours? Even working at night, we will still need to block pedestrian traffic the following day.

Are there alternate ways for the employees to access their offices, cafeteria the auditorium, etc.?

Answer: Drawing G.0.05 indicates in regard to the terrazzo floor, “Stage Pours to allow passage at all times”. The contractor will be responsible to phase the work so that the building occupants can get around the building with the minimal impact. The contractor will need to submit a plan for review and approval that will address building tenant access. Terrazzo flooring work should be performed during building unoccupied working hours.

Answer: Looking at the ductbank sections on EP-1-01 it calls out for “Stone free clean, dry backfill mechanically tampered in layers not exceeding 6” in depth,” not for the fill to be stone. Yes the lawn should be restored.

New Parking Lot Lighting.

Will temporary lighting be required during the period when the old parking lot light poles are demolished and the new light pole are constructed, wired and energized?

Answer: Temporary Lighting is not required. The building will operate the center pol light and perimeter lighting that will be unaffected by the project work.

Similar Projects The Solicitation defines similar projects as Security Systems installation, Projects including structural steel and Curtain wall glazing system and Waterproofing projects.

Appendix E defines similar projects as New construction of office building of approximately 10 million or more. Please clarify which type of projects we are to submit as Similar Projects.

Answer: Similar projects are as defined in the solicitation, not Appendix E.

Owner Evaluations Appendix E The first paragraph states “….forwarded by your firm to the TWO owners you have selected on the Three projects proposed for evaluation…” Please clarify what you are requesting when stating “two owners” and “on the three projects”.

Answer: Each project submitted must have one owner evaluation submitted for each project. Reminder – evaluations are to be sent via email directly to the contracting officer from the evaluator.

Schedule Submission with Proposal You are requesting an extremely detailed schedule to be included in our proposal. That level of detail for a project of this complexity would require at least 30 days and a lot of money to develop. In reality to do it correctly, input from Building Management, Owner and Contractor would be necessary before we could provide a schedule that we would be comfortable with that “will be incorporated into the contract as part of the award.” There are many variables that need to be discussed with the users so the schedule can accommodate the needs of all parties. 700 days to complete is certainly achievable but to require this much detail prior to award is extremely onerous. Would it be possible to change the requirements to something that demonstrates the bidders ability to schedule the work rather than require a actual full blown schedule before we are awarded the project?

Answer: The schedule required to be submitted with the proposal should include key milestone durations for each phase. The more detailed schedule will be required to be submitted after award and notice to proceed.
