QUESTION/ANSWER FROM INDUSTRY

Question #1: Due Date. On FBO is stated it is due at 10/15 at 3 and on the solicitation it states it is due 10/15/19 @ 12:00 p.m. Which is correct?

Answer #1: The due date is 10/15/2019 at 3PM.

Question #2: Delivery: How is the final proposal being submitted? Email, Hand Delivery, Commercial Carrier?

Answer #2: Email is the preferred method.

Question #3: What is the estimated price range for this project?

Answer #3: This is a commercial service contract and not a construction contract. Estimated price ranges are used in construction contracts and not commercial service contracts.

Question #4: If you already have access to the base, do you have to submit the site visit forms?

Answer #4: No.

Question 5: Please provide all available as-builts for the proposed work area for B1490. For bidding purposes and to clarify SOW, necessary as-builts (and their purpose) are as follows:

Structural - To show true floor to deck height throughout and to help identify areas where structural steel above walls will need to be built out to achieve STC 50.

Plumbing/Mechanical – To help quantify ductwork to receive man bars/to quantify the number of air/water lines being removed and identify their shut-off location

Electrical/Comm – To quantify the data ports/wire/electrical devices to be removed. Please mark these up to identify items requested to be removed.

Architectural – To identify areas where existing drywall/insulation are not up to STC 50 requirements/To possibly identify the maker of the existing raised floor system to avoid having to replace the support frame.

Answer 5: As-builts are not available.

Question 6: Please provide onsite supervision requirements for this project. Will dedicated SSHO/QC/Superintendent personnel be required to be onsite at all times and if so please quantify the number of individuals and minimum experience/training requirements?

Answer 6: No, the SSHO/QC/Superintendent personnel will not be required to be onsite at all times, but the Contractor shall provide supervision, safety, and quality control to ensure the project complies with building codes, safety codes, and inspection guidelines.
