reference AC-103

17) Construction Phasing and Vacated Areas

Our understanding from the meeting is that FDOT will vacate the affected work areas and permit construction in one designated section at a time.

Please confirm the maximum number of work areas that may be under construction simultaneously, how areas will be released to the contractor, and whether FDOT will relocate furniture, computers, and personnel before work begins.

1 floor at a time and FDOT will remove all personal items and place all other items under counter tops. Cubicles will NOT be removed and the contractor must stage above and/or around all furniture.

18) Contract Duration and Manufacturer Lead Times

Given the substantial equipment procurement requirements and limitations on construction phasing, would FDOT consider adjusting the contract completion schedule based on confirmed manufacturer delivery dates?

Would FDOT consider a 365-calendar-day construction period following delivery of the major equipment, or another contract provision allowing schedule extensions for documented manufacturer delays beyond the contractor's control?

Yes. For bidding purposes you must stick to the approved schedule at this time.

Any adjustment will require manufacture justification.

19) Daikin Equipment and Approved Substitutions

Please confirm whether Daikin is the sole approved manufacturer for the scheduled chillers, air handlers, and VAV equipment.
