This Admin Mod is in regards to a construction condition regarding the roof hatch access in Building A.The current installation of the required roof hatch does not meet the 2012 IBC requirement for a roof hatch. However,we believe that the intent of providing access to the roof for firefighting purposes has been met. Per IBCSection 1009.16.1 Roof Access: "Where a stairway is provided to a roof, access to the roof shall be provided through a penthouse complying with Section 1509.2". Exception: "In buildings without an occupied roof, access to the roof shall be permitted to be a roof hatch or trap door not less than 16 square feet (1.5 m2) in area and having a minimum dimension of 2 feet(610 mm)". The current dimensions of the roof access hatch are 32"x 48",which provides an opening of 10.6 sq. ft. While this falls short of the required 16 sq.ft., it does meet the requirement and intent of having a minimum dimension of 2 ft. to a non-occupied roof as stated in the exception above. The hatch will not be used to take large mechanical equipment to the rooftop.Any repairs to the large mechanical equipment will require the use of a crane to hoist large equipment to and from the roof. In addition the 48" dimension of the opening is orientated in the north/south direction,thus allowing Fire Department access by firefighting staff should a fire event occur at Strata Vail.
