See the following questions with answers.

1. Q: Just to clarify, the FP contractor shall be responsible for all associated cost from the mainland to the Island for all materials, equipment, tools, manpower, and lodging, correct? Most likely we would need to get in and demo our piping in the restroom areas and come back when all framing is completed (probably after the first of the year).

A: This bid package is for General Construction. Sub-contractors, including FP contractor, to provide their quotes directly to the General Contractors bidding. Scheduling of work will be the responsibility of the General Contractor.

2. Q: Will the fire suppression system need to remain in service during construction? I’m assuming that we can plug off the required openings primarily in the restroom area and place the system back in service just leaving the renovated areas out of service.

A: The system to remain in service as much as possible. It is understood there will be downtimes such as during the replacement of the fire riser. Downtimes should be minimized. Multiple trips etc should be planned to minimize system downtime.
