3. Under Description of Supplies/Services in the Price/Cost Schedule, page 5 – it’s referenced that the “Contractor to provide all supervision & labor for corrective, repair, or emergency services on all the equipment listed in the Statement of Work” however, in the SOW Contractor Requirements, Item 5, it states that “Service request outside the scope of services will be billed on a separate PO and will be authorized by the VA before start of work.” Can the government give clarification on this apparent contradiction?

Upon request, the Contracting Officer will make their full text available. The following clauses are incorporated into 52.212-4 as an addendum to this contract:

6. Regarding Labor for Emergency Services and Callbacks: Contractor concern is that the annuals have not been completed in a year and a half.

· Page 7, item #10, it’s understood that there may be some deficiencies with the cooling towers that require attention.
