We have very relevant past performed project, but value is about JPY 670,000,000. Would such over value ranging project be out of your evaluation or lower rating?

PPI relevancy will be evaluated based on scope, complexity and magnitude. Very Relevant contract performance efforts involved essentially the same scope, magnitude of effort, and complexities to that required by this solicitation. In addition, the performance must have been concurrent (overlapping performance periods) with at least one other project of equal or greater magnitude and performed at a separate geographic location.

Any project greater than the range will not be negatively evaluated for the magnitude of effort portion to determine relevancy.

36) L-100, B.1.(g) Contractor Teaming Arrangement

Is the word “Teaming” interpreted as a joint venture (JV)? We plan to participate in bidding as a prime contractor, and we will work with design companies and subcontractors for each of the orders (Task Orders). In this case, it is determined that it does not correspond to "Teaming". Is this correct? Or is the “Contractor Teaming Arrangement” to include the design companies and subcontractors? Please advise.

Please refer to FAR Subpart 9.6 -- Contractor Team Arrangements. “Contractor team arrangement" means an arrangement in which --

(1) Two or more companies form a partnership or joint venture to act as a potential prime contractor; or

(2) A potential prime contractor agrees with one or more other companies to have them act as its subcontractors under a specified Government contract or acquisition program.

Reference QUESTION Answers

66 1. Government response on the Q & A for FA5209-19-R-A006 for new building’s hazard classification was Ordinary Hazard, Group 2 per NFPA 13. This may not be appropriate since OH, Group 2 requires sprinkler water density of 0.20 GPM/SF and due to the following reasons below a higher sprinkler water density is required.

a. SOW section II.C.1, requires the storage facility to be steel frame structure building. UFC 3-600-01, para. 4-44.4 requires steel columns must be protected as required by NFPA 13. Table 20.15.1, NFPA 13 requires 0.68 GPM/SF (27.7 mm/min) for 4 feet (1.2m) aisle and 0.57 GPM/SF (23.2 mm/min) for 8 feet (2.4m) aisle ceiling sprinkler density for protection of steel columns.

b. UFC 3-600-01, para. 4-44.2.3.1 requires sprinkler protection, at a minimum, must be based on Class IV, non-encapsulated commodities, as defined by NFPA 13, unless a more severe class of storage is anticipated, and must be based on the maximum potential height of storage. To determine the appropriate design sprinkler density, please advise the storage height and storage arrangement like racks/shelves, hazardous materials, etc. The required design sprinkler density could be higher than OH, Group 2 (0.20 GPM/SF) depending on the storage arrangement and materials stored in the facility.

Please confirm if the contractor shall design and install the sprinkler based on Ordinary Hazard, Group 2 Hazard Classification or the Fire Protection Engineer (FPE) shall determine the appropriate Hazard Classification and design density of sprinkler system protection of the new facility.

b. New racks/shelves, approx 3,600mm height x 1,200mm depth x 10,800mm wide shall be installed along the east side wall. Aircraft parts (mostly made from metal that contains some rubber and plastic) and support equipment (machine tools and viecles) are not high rates of heat release and will be stored.

Fuel, oil and combusitble or flammable liquid will not be stored.

The Fire Protection Engineer (FPE) shall determine the appropriate Hazard Classification and design density of sprinkler system protection of the new facility.

67 SOW section II.D.2 SOW section II.D.2, please clarify that the two (2) new heat pump unit is split type with ceiling or wall mounted indoor unit and outdoor unit. The outside air intake fans with heat exchanger is in other technical term an Energy recovery ventilator with associated ducts system for outside air ventilation requirement for the two office spaces. Please confirm.

Yes, it shall be acceptable.

68 Mechanical SOW item 3 Mechanical SOW item 3, requires replacement of existing unit heaters, steam piping, traps, and valve with new and point of connection at building 906 border. This is assuming that the existing steam supply line or capacity is sufficient to support the new space heating requirement of the new storage facility. Please confirm that upgrading or replacement of the existing steam supply line for appropriate new size beyond the building 906 border shall not be part of the contract and shall be by others.

Yes, the capacity of existing steam supply line shall be sufficient to support the new space heating requirement.

69 Mechanical SOW item 1 Mechanical SOW item 1, the concept drawings doesn’t show bathroom and the existing building doesn’t have either. Please clarify for the replacement of existing water piping and valve with new indicated in the SOW.
