1) Question: Provide the make, model, and service provider for the site’s fire alarm system.

Answer: Fire & Life Safety America (FLSA) is the existing service provider for the facility. The make and model of the Fire Alarm Control Panel is not needed to provide accurate pricing for this project and will not be released at this time.

2) Question: Please confirm the makes and models of the panelboards power will be supplied from.

Answer: Square D Company is the manufacturer for existing power panelboards. Schneider Electric is the manufacturer of the majority of DDCP. Additional information will be collected by the contractor following award. Reminder, all aspects of electrical work must comply with FAA-C- 1217H per 26 05 00 – 3.1.A.

3) Question: Confirm that any hazardous materials (lead, mold, asbestos, etc.) encountered during construction will be dealt with as a differing site condition. As a result, a change order will be issued to the contractor for unforeseen circumstances.

Answer: Yes, any hazardous issues (or non-hazardous issues) that arise that are not part of the current contract requirements and that fall under the definition of a “differing site condition” will

4) Question: Confirm that the contractors are to follow the provided phasing plan on Sheet G005.

Answer: Contractors are to follow the provided phasing plan on sheet G005. Changes or adjustments to the phasing plan may be submitted to FAA for review after contract award, and must be approved by the Contracting Officer’s Representative (COR) prior to the issuance of the Notice to Proceed.

5) Question: Has a project-specific environmental survey been completed for this project? If so, please provide a copy.

Answer: An EOSH review was completed specifically for this project. No hazardous materials (asbestos, lead paint, etc.) were discovered during the survey. A copy of the survey will not be provided.

6) Question: Confirm 5-year manufacturer extended warranties are to be provided for all installed equipment.

Answer: The Contractor shall warranty material and equipment furnished by the various manufacturers in writing for a minimum period of one (1) year. If any manufacturers provide a standard warranty in excess of one year, the expectation is that the FAA will receive the industry standard warranty for the material and/or equipment. The warranty period will be no less than the manufacturer’s standard warranty period, or one year, whichever is greater, on building systems, finishes or equipment, from the date of final project acceptance by the FAA.

7) Question: Confirm no extended maintenance plans are required past the completion date and FAA personnel will provide maintenance for the installed systems and equipment after project turnover.

Answer: See answer to Question 7.

8) Question: Is the site chilled water to be left as-is and used for this project? Will the contractor be responsible for adding glycol to the system? If so, how much glycol will the contractor be required to add to the system?

Answer: The contractor will not be required to add glycol to the existing chilled water system.

The contractor will not be required to install expansion tanks. Hydronic piping modification is minimal. Review Phase II plans, specifically for AHU 206.

Answer: Review G004 Mechanical Note 12. Contractor shall provide temporary air conditioning sufficient to maintain operating zone temperatures and humidity. The G004 phasing plan describes conditions that temporary air conditioning may not be needed. Requirements for tons/BTU and CFM will differ seasonally, refer to the Mechanical Equipment Schedules on M136, M137 and M138.

13) Question: Will the FAA provide security escorts for all work at the facility? If yes, will all work at the facility need to be performed under the supervision of a security escort?

Specifications, Rev. 1.

The contractor and their subcontractors will be required to escort their project work crew. A discussion between the FAA and the contractor will be had after contract award to determine a practicable number of contractor/subcontractor workers to be badged so they can provide enough escorts for efficiency and to ensure that the project work is not hindered and will progress as reflected in the contractor’s final approved schedule.

14) Question: Confirm work is to be performed during normal business hours.

Answer: See Specification Section 01 10 00 1.8.B On-Site Work Hours. Most work will take place during normal work hours, however, refer to response to question 10 for work that will take place outside of “normal work hours”.

Answer: Yes, relevant CPARs evaluations may be submitted in lieu of past performance surveys. The contractor must provide the CPARs documentation in their technical proposal.

21) Question: Does a subcontractor/small business subcontracting plan need to be provided if the offeror is a small business?

Answer: Section Section J (page 46) of the RFO and Contract Clause 3.6.1-4 verbiage. The subcontracting plan requirement only applies if the contract is awarded to a large business.

22) Question: The specifications refer to Attachment B – Site Photos. Please provide site photos.

Answer: See Attachment 1 – Specifications, Rev. 1, with the following changes:

1) Removal of reference to Attachment A: Drawings. The drawings are titled “Attachment 1(a) – Drawings” in the contract documents. This conflicts with the reference in the specifications, so the specification reference has been removed.

2) Removal of reference to Attachment B: Site Photos. Site photos are not being provided, therefore, the specification reference has been removed.
