Additional Contractor Questions and Answers: (AMEND 3) Question: Scope of work page 15 of 87, Infra-Red Scanning: states 'problem connections shall be replaced with new connections, and/or tightened with torque wrench to meet the equipment manufacturer's sections.'. It is not possible to estimate the no. of connections to be replaced or tightened during the proposal stage. We suggest the VAMC should consider issuing an additional scope/change order during project execution to replace or tighten the connections based on the no. of such locations found from the Infrared scanning.  Answer: In the past, there were less than 10 loose connections that needed to be tightened. Question: Scope of work page 17 of 87, Coordination and short circuit study states 'Protective equipment shop drawings shall be submitted simultaneously with or after the protective device study. Protective equipment shop drawings will not be accepted prior to protective device study.' Please clarify the intent of these equipment shop drawings. These are existing equipment and normally shop drawings are required for new or upgraded equipment. There is no upgrades being performed under this project. So, we believe shop drawings are not required. Please clarify. Answer: New drawings are still required to verify accuracy of equipment. Question: Scope of work page 5 of 87, 3. Summary of Work, Para C.2.(a) states to provide laminated, adhesive-backed flash and shock hazard/PPE signs for each system location will be provided and installed. Normally these types of signs are not provided and have not been found during our walkthrough at both project sites. Please clarify the intent of such a sign and provide samples and quantities of such for our estimation purpose, unless VAMC finds that such signs are not required Answer: Consider the Sign as a label, and these are required to readable in both indoor and outdoor environments for at least 3 years whether laminated or not. Question: Amendment #2 RFI response #16 - it is not possible to accurately determine the # of circuit breakers that require testing based on this response. Please provide the quantity of circuit breakers that require testing i.e. x breakers from the Bowling inventory list and x breakers from the Sousley inventory list require testing. Answer: Bowling campus has 106 total breakers and relays (Main building 25, Tower Building 53, Chiller building 28). We do not have an accurate inventory to provide an exact number for this campus. It is possible there is somewhere around 70 breakers that will need trip units tested. Question: Amendment #2 RFI response #16 to clarify, we will provide a schedule for the preventative maintenance but we need the VAMC to tell is when outages can be scheduled for their buildings and equipment. Please confirm. Answer: All outages will be coordinated with the VA with an Outage Request submitted at least 10 days in advance. Question: Can we schedule outages to service any equipment after 5PM on the weekday? If so, please clarify which buildings and equipment can be serviced during this time. Answer: Maybe at Sousley but not at Bowling. Question: Amendment #2 RFI response #24 - this question is regarding the VAMC owned equipment. Can all equipment be de-energized for up to 8 hours? If not, please clarify what buildings and equipment have outage restraints or require rolling outages? Answer: No. Some equipment at Bowling can be off for that long. For example, the Chiller Plant can be shut off when the outside temperature is below 40 degrees Fahrenheit. Question: The VAMC equipment inventory list does not match the test report that was provided. Should we use the inventory list and drawings to provide an accurate quote? Answer: Please use the one that has the most equipment to provide the quote. Question: The contract states the preventative maintenance shall be completed within 90 calendar days of contract start date. The circuit breakers should be set and tested after the newly provided coordination study is complete, so this may not be enough time to complete both tasks. Can the preventative maintenance completion date be extended? Answer: Maybe. No further questions will be accepted.

Unless otherwise stated in this clause, a requirement in 13 CFR part 121 and 125 that applies to an SDVO SBC, is to be construed to also apply to a VIP-listed SDVOSB. For the purpose of limitations on subcontracting, only VIP-listed SDVOSBs (including independent contractors) shall be considered eligible and/or similarly situated (i.e., a firm that has the same small business program status as the prime contractor). An otherwise eligible firm further agrees to the following: (1) Services. In the case of a contract for services (except construction), it will not pay more than 50% of the amount paid by the government to it to firms that are not VIP listed SDVOSBs. (2) Supplies or products. (i) In the case of a contract for supplies or products (other than from a nonmanufacturer of such supplies), it will not pay more than 50% of the amount paid by the government to it to firms that are not VIP-listed SDVOSBs. (ii) In the case of a contract for supplies from a non-manufacturer, it will supply the product of a domestic small business manufacturer or processor, unless a waiver as described in 13 CFR 121.406(b)(5) has been granted. (3) General construction. In the case of a contract for general construction, it will not pay more than 85% of the amount paid by the government to it to firms that are not VIP-listed SDVOSBs. (4) Special trade construction contractors. In the case of a contract for special trade contractors, no more than 75% of the amount paid by the government to the prime may be paid to firms that are not VIP-listed SDVOSBs. (5) Subcontracting. An SDVOSB must meet the NAICS size standard assigned by the prime contractor and be listed in VIP to count as similarly situated. Any work that a first tier VIP-listed SDVOSB subcontractor further subcontracts will count towards the percent of subcontract amount that cannot be exceeded. For contracts referenced in (d)(2), (3), and (4) the cost of materials is excluded and are not considered to be subcontracted. When a contract includes both services and supplies, the 50 percent limitation shall apply only to the service portion of the contract. Other direct costs may be excluded to the extent they are not the principal purpose of the acquisition and small businesses do not provide them. For additional information and more specific requirements on the limitations on subcontracting, refer to 13 CFR 125.6. (e) Required limitations on subcontracting compliance measurement period. An SDVOSB shall comply with the limitations on subcontracting as follows: ____By the end of the base term of the contract or order, and then by the end of each subsequent option period; or ____By the end of the performance period for each order issued under the contract. (f) Joint ventures. A joint venture may be considered eligible as an SDVOSB if the joint venture is listed in VIP and complies with the requirements in 13 CFR 125.18(b), provided that any requirement therein that applies to an SDVO SBC is to be construed to apply to a VIP-listed SDVOSB. A joint venture agrees that, in the performance of the contract, the applicable percentage specified in paragraph (d) of this clause will be performed by the aggregate of the joint venture participants. (g) Precedence. Any inconsistencies between the requirements of the SBA Program for SDVO SBCs, and the VA Veterans First Contracting Program, as defined in VAAR subpart 819.70 and this clause, the VA Veterans First Contracting Program takes precedence. (h) Misrepresentation. Pursuant to 38 USC 8127(g), any business concern, including all its principals, that is determined by VA to have willfully and intentionally misrepresented a company s SDVOSB status is subject to debarment from contracting with the Department for a period of not less than five years (see VAAR 809.406, Debarment).
