H. Fire Protection/Life Safety

Per UFC 3-600-01, a fire protection design analysis is required for major projects and must address the fire protection requirements of the project as required by this UFC. This design analysis summarizes fire protection features that are required versus features that are provided.

Work on this project is generally defined as ‘modification’ and ‘reconstruction’ work per UFC 3- 600-01, Chapter 34. Therefore, work must conform to the requirements for ‘new construction in UFC and NFPA 101.

Comply with UFC 3-600-01, Chapter 34, for phasing of construction and coordination of fire protection and life safety features during construction:

• Phasing of construction and demolition operations must be planned so that the integrity of fire-rated separations, smoke-tight boundaries, means of egress, exit enclosures, and vertical openings are maintained to the highest level possible.

• The phasing plan must ensure that obstruction of the means of egress is avoided or minimized.

• If exits are obstructed during construction, provide alternate means of egress and exit routes during each phase of construction and identify the alternate routes on the construction drawings as part of the phasing plan(s).

• Minimize, to the extent possible, any impairments or disruptions to active fire protection features. Delineate phasing of construction to ensure that installations of new features (or systems) or modifications to existing ones are expedited.

• Where possible, maintain existing systems in service until the replacement work has been deemed operational.

• Prior to taking any actions to impair a fire protection feature or disrupt its performance, ensure alternative procedures have been prepared and incorporated and confirm that official notification of system impairments and schedules have been given to the staff of the Facility.
