CONTRACT OFFICER

VENDOR QUESTIONS & ANSWERS

1. Additional Sampling Scope: Our standard investigation methodology includes three air samples per visit -- two indoor samples and one outdoor control. In the event the COR requests additional samples beyond that standard scope during a single investigation, can the additional sampling costs be billed as an overage against the base CLIN, or would that require a separate contract modification?

The COR cannot authorize additional sampling. The CO must authorize the additional service before any additional services of any sort. A modification must be in place before any additional services can be started. If the vendor performs the services without the awarded modification, the contractor is doing it at their own expense. The Government did not authorize such services.

2. After-Hours and Holiday Emergency Response: The PWS requires a two-hour emergency response and notes that some work may be required outside normal business hours. The contract is firm fixed price per investigation. If the VA issues an emergency requirement outside normal business hours or on a federal holiday, is the per-investigation price the same, or is there a mechanism to address premium pricing for after-hours emergency response?

Additional CLINS have been added for After Hours, Holiday and Emergency services. Please refer to the updated Price/Cost Schedule in amendment 0001.

3. Subcontractor Approval: The solicitation states that any subcontractors must meet all requirements of the prime contractor and be approved by WNCVAHCS. Is subcontractor approval required prior to award, or is that process initiated post-award?

It will be Post-Award.
