FTFA 03-1231 REPLACE HVAC BUILDING 129

REQUEST FOR INFORMATION (RFI)-5

Q1: What are the hours of the sheet metal shop? Will we be allowed to work while they are working within this area?

A1: The hours for the Sheet Metal Shop are 0630 - 2400 hours (Monday thru Friday and Weekends - per mission requirements). It will be possible with coordination (in advance) between facility managers, contracting officer and PM.

Q2: Will we be allowed to “Lock-out Tag-out” the overhead crane during regular sheet metal shop hours?

A2: The Crane issue, however, is a moving target. (Metals Tech shop uses as well) The Crane's use is based on our mission requirements which at times pop up unexpectedly.

I.e. when something (heavy) arrives that needs to be brought back to production machines, or product is finished and needs to be lifted / moved / lowered to a truck, the crane is required.

Once we get a firmer time frame- when it will actually be required to be "locked out", we will do our best to advance schedule / accommodate / advance position items (be flexible). If contractor can be flexible too, we should be able to work around / complete mission requirements, while locking the crane in place for their required period of time.

It will be possible with coordination (in advance) between facility managers, contracting officer and PM.
