Solicitation Questions/Answers - Lighting Project Bldg. 299

Question 1: Is another site visit available to be able to accurately fine-tune our bid prior to the bid due date?

Response 1: No.

Question 2: Will there be on-site storage available for the new light fixtures? A loading dock to receive the products? Will contractor need to be on-site to receive?

Response 2: a. On site storage is available depending upon the area required for storage of the light fixtures.

b. No, a loading dock will not be available.

c. Yes, the contractor must be on site for receipt of materials.

Question 3: Will the government provide dumpsters for demolition debris, or is the contractor responsible for furnishing, placing, and removing dumpsters for all waste and recycling? Are there minimum recycling targets or required facilities for disposal?

Response 3: a. Dumpsters shall be provided and maintained by the contractor.

b. There are no specified recycling targets.

Question 4: The new high bay light fixtures are specified as BAA. No other fixtures are specified BAA.

Are non-BAA alternatives acceptable for those that are not specified as such?

Response 4: The “other fixtures” are required to be BAA. The model numbers are incomplete. The contractor is required to finalize the model numbers as part of the design build process.

Question 5: Is there a specific air conditioner unit manufacturer the Government would prefer contractor install? Perhaps the same as existing?

Response 5: Mitsubshi is the most common unit in use. However, there is no requirement to use this manufacturer.

Question 6: Is the Contractor responsible for interpreting both the Existing and New Fixture schedule to determine what New fixtures should replace existing fixtures - or will the government provide a cross for each existing fixture listed?

Response 6: This is a Design-Build Contract. The designer is responsible for determining appropriate replacement light fixtures.

Question 7: Can contractors use the government’s on-site aerial lift(s) if available?

Response 7: Government equipment is not available for use by the contractor.

Question 8: Is there a minimum size required for each battery room? Maximum?

Response 8: This is a Design-Build Contract. The designer is responsible for determining an appropriate size for the battery rooms.

Question 9: Is the government open to considering the EXIT and Emergency lighting added on separate dedicated circuits as specified, but without the addition of (2) centralized battery rooms?

Response 9: The question implies that the contractor is looking to install emergency batteries in the light fixtures. This is not acceptable.

Question 10: During the site walkthrough, it was stated that the awarded contractor will be required to construct two (2) dedicated battery rooms. Please confirm if this is a firm requirement and clarify where this is addressed in the solicitation or specifications.

Response 10: The two proposed battery rooms are shown on Drawings L-102, Keynote 51 and L-120, Keynote 18.

Question 11: If two battery rooms are required, will the Government provide designated locations within Building 299, or should the contractor propose locations as part of the 60% design submittal?

Response 11: Refer to the response to question 11.

Question 12: Are there specific dimensional, ventilation, or fire-rated construction standards that the battery rooms must comply with beyond the referenced codes (e.g., NFPA 70, 101, 855, UFC)? For example, should these rooms be designed to meet battery energy storage room criteria per NFPA 855?

Response 12: This is a Design Build Project. The designer is responsible for determining code requirements.

Question 13: Is the requirement for two battery rooms driven by electrical load zoning (e.g., serving separate electrical panels or wings of the building), or for redundancy/resiliency purposes? Please clarify the intended distribution.

Response: 13 The voltage drop with one battery room will be too great according to our preliminary calculations.

Question 14: Should the central battery system be designed to power all egress and emergency lighting fixtures throughout the facility, or only certain areas (e.g., NW zone) covered under this requirement?

Response 14: The battery systems shall be sized to handle the specific emergency light fixtures as shown on the drawings.

Question 15: Are there existing battery rooms or electrical spaces in Building 299 that the Government recommends repurposing or expanding, or should both rooms be entirely new construction?

Response 15: The battery rooms shall be new construction.

Question 16: Our interpretation of the documents led us to believe there was the requirement for only (1) battery room, however, during the non-mandatory walk-thru it was uncovered the Government wants (2). Does the price range for the project ($1M - $5M) take into account (2) battery rooms? Also, will those that did not attend the walk-thru be made aware that the requirement is (2) battery rooms? Their price may be submitted under the assumption there is only (1) battery room required.

Response 16: Two battery rooms are clearly shown on the preliminary drawings.

Question 17: Is all emergency lighting wiring required to be run in conduit or is MC cable or plenumrated wiring acceptable?

Response 17: All new wiring shall be in conduit.

Question 18:

Referencing the new lighting work in blueprints, there are some pages (L-401 through L412) that have new light fixtures denoted with numbers that do not exist (F70, F62, F80, etc) on the New Lighting Legend (which ranges from F1 - F18). Can you please clarify that this is an error on your end because all New Lighting on pages L-101 through L-135 comply with New Lighting Legend.

Response 18:

Response: Drawings L-401 through L-412 show the light fixture designation in the “Existing Lighting Legend.” As part of the Design-Build process, the contractor is responsible for determining the new fixture requirements and model numbers.

Question 19: Can you please clarify what these Fixtures in pages (L-401 through L412) should be?

Response 19:

Drawings L-401 through L-412 show the light fixture designation in the “Existing Lighting Legend.” As part of the Design-Build process, the contractor is responsible for determining the new fixture requirements and model numbers

Question 20:

Elsewhere in the New Lighting Blueprints there are light fixtures suffixed with ?? (IE F??) are these new light fixtures TBD by contractor?

Response 20:

The available existing lighting drawings did not identify the style or type of the existing light fixture in these areas. As part of the Design-Build process, the contractor is responsible for determining the new fixture requirements and model numbers.

Question 21:

Some areas in New Lighting Blueprints have general notes but are missing light fixtures (L-410 through L-414), are these areas remaining without New Light Fixtures?

Response 21:

The available existing lighting drawings did not identify the style or type of the existing light fixture in these areas. As part of the Design-Build process, the contractor is responsible for determining the new fixture requirements and model numbers.
