25 How many working days can the contractor assume per week during the winter schedule? Will working days be consecutive or alternating?

The previous RFI responses did not provide enough information for the contractor to accurately put a timeline to this scope of work. This will factor in greatly to project duration and scheduling.

SOW section 3.2.A&B On-site work hours: Work shall be generally performed during normal business working hours of 8 a.m. to 5 p.m., Monday through Friday, except when otherwise indicated.

A. Work on Saturdays, Sundays, Federal holidays, early morning, or at night may not be performed without prior consent from the CO and COR. Submit requests for work outside of the stated normal business hours to the CO and COR for approval at least 48 hours in advance of the work. The contractor will need to determine the timeline factor based on this information.

26 Downtime will likely consist of multiple consecutive days. Does the contractor need to account for temporary temp controls for the ENTIRE square footage of the facility? Or can only certain areas or floors be provided temporary services during the outage?

SOW section 3.8.A.1.b

1. Full Government Occupancy: Government will occupy buildings that will be under construction during the entire contract period. Cooperate with Government during construction operations to minimize conflicts and facilitate Government usage. Perform the Work so as not to interfere with Government's day-to-day operations.
