B203004 OVERHEAD ROLL-UP AND OVERHEAD SECTIONAL DOORS

NOTE:   Overhead doors may only be used if they open into an unoccupied space because of ATFP restrictions or if the facility type is exempt from ATFP requirements such as car repair shops.  Overhead roll-up doors could possibly be designed to meet ATFP requirements but confirm that blast testing has been accomplished by the door manufactures before requiring these doors to provide entrance or exit from an occupied spaces.  No overhead doors have been tested as of the writing of this NOTE.  Refer to UFC 4-010-01, DoD Minimum Antiterrorism Standards for Buildings for ATFP requirements.

Special sliding, exterior folding, or telescoping doors need to be added to RFP Part 3 and RFP Part 4.

Design doors and opening for [automobile] [___] entrance.  Provide lockable doors with [manual operation] [automatic operation with protected pushbuttons electric controls].

Accomplish door operation by [lifting handles and pull rope] [hand chain with gear or sprocket reduction] [hand crank with gear or sprocket reduction] [UL Listed electric motor operation with electric controller and an auxiliary hand chain operation.] [Provide [slat] [panel] profile to match existing overhead doors on the [___] facility.]   Also provide counterbalance, heavy duty springs, wear strips, full perimeter weather-stripping, [continuous button pressure safety operation,] electric or infrared safety edge, galvanized hardware, and manufactured trims and closures pieces.  Protect the wall door jamb opening with guards designed to resist abuse from the type of material and vehicles that are transported through the opening.

NOTE:  ANSI/DASMA 102 provides two level of durability for overhead sectional doors, as follows.  Choose one in the following paragraph.

a. Residential.  Intended for use in a residential garage, and normally expected to be operated less than 1,500 cycles per year.

b. Commercial.  Intended for vehicular use at entrances of commercial buildings such as loading docks, service stations, parking garages and manufacturing plants, normally expected to be operated but not limited to less than 5,000 cycles per year.

NOTE:  The standard painted finish for overhead doors is typically two coats of baked-on polyester paint and comes in limited color choices.  Choose the powder coat option below if environmental conditions require more weather resistance.  Powder coat finish last much longer than the standard paint but does not accept scratch repair or repainting as easily as polyester.

NOTE:  Determine if the overhead roll-up doors have to be operational in ASCE 7 ( hurricane) wind loading. Choose the bracketed option below if roll-up doors are required to be operational at all times.  Typically the steel slat gauge and width of the roll-up door will be limited if operation during high wind conditions is required.  With the minimum insulated steel slat gauge specified in RFP Part 4, you cannot expect a door opening wider than approximately 8'- 0" before the curtain wind locks begin to engage and restrict the door operation at ASCE 7 wind loading.  By increasing the slat gauge to a maximum thickness in RFP Part 4, you cannot expect an overhead roll-up door opening wider than approximately 10'-0'' to operate in ASCE 7 wind loading.  Overhead sectional doors operate better than overhead roll-up doors in high wind conditions.
