PART 2-DESCRIPTION

FIRE TRAINING SIMULATOR 

2.1	PURPOSE:

This structure will be used to provide training for fire fighters and leaders in controlled environments, which replicate actual conditions.

2.2	GENERAL:

The fire training structure/tower shall utilize a structural steel frame system and curtain wall design. Structural framing systems are considered the norm for high-rise and commercial structures.  The curtain wall/exterior wall panel design produces an ideal buffer or protection between the main structural frame of our building and any exterior elements, so that if an exterior wall panel is damaged (i.e., fire truck hits the side of the tower) no structural damage is likely to occur.  This wall panel system also creates a flat surface ideal for ladder or rappelling anywhere on the tower to simulate actual street conditions.

2.3	STRUCTURAL INTEGRITY:

The wind loads, deck and the roof loads stated herein represent the standard criteria.  Increased loadings, as may be dictated by local jurisdictions, will be accommodated.  The primary structural system shall utilize hot-rolled structural steel column and beam frames sized to meet and exceed the loads as indicated.  This training simulator shall be considered a nonbuilding structure for both code compliance and load interpretation.  The primary and secondary structural system shall also meet and exceed the loads as indicated while maintaining a maximum deflection of L/240.

2.4	CODE COMPLIANCE:

The fire training structure/tower’s primary structural and seismic design shall be in accordance with the building code having jurisdiction in the area of the project.  Due to the unique nature of the intended use of these fire training structures/towers; handrail extensions, guard openings, riser openings, means of egress, fire wall requirements as well as other construction issues, are not expected to satisfy the criteria of buildings intended to accommodate public occupancy. This may require a building code variance in some locations; however, this simulator shall meet applicable building codes and NFPA 1402 standards. It is the responsibility of the owner to obtain such variance if required.  

2.5	MATERIALS:

All materials shall be new and shall conform to applicable ASTM specifications.  All structural or nonstructural materials used, 10 gauge or less in thickness, whether exposed or not to the elements shall be hot-dipped galvanized. When any mention of galvanized is noted within these specifications, it shall be implied to mean hot-dipped galvanized.  Any exposed material which is not galvanized, shall be given one coat of shop paint.

2.6	FASTENERS:

All fasteners utilized with galvanized steel panels not exposed to the elements shall be electro-galvanized.  All exterior fasteners shall be furnished with a contained EPDM washer under the head for sealing.  Structural columns and beams shall be field bolted with (A325) 5/8” diameter electro-galvanized bolts or larger.  Anchor bolts shall by furnished by the concrete contractor, unpainted and of the size specified on the anchor bolt plan.

2.7	WEATHER SEALING:

All joints in weather tight areas are to be sealed with tape caulk or foam closures as specified on the building plan.  Because of the intended use water tightness of simulators is not required or assured.

2.8	ROOF SYSTEMS:

Roofs shall be decked with 30" or 36" wide, 18 ga. unpainted galvanized 18 gage steel deck per ASTM A-653, class G60 with recessed fasteners and shall meet the stated design load.
