VERTICAL LIFT FABRIC DOORS

08/21, CHG 2: 08/24

NOTE: This guide specification covers the requirements for vertical lift fabric doors.

Adhere to UFC 1-300-02 Unified Facilities Guide Specifications (UFGS) Format Standard when editing this guide specification or preparing new project specification sections. Edit this guide specification for project specific requirements by adding, deleting, or revising text. For bracketed items, choose applicable item(s) or insert appropriate information.

Remove information and requirements not required in respective project, whether or not brackets are present. For example, if providing a single door (leaf) remove requirements for mullions, mullion pits,and other applicable door elements.

Comments, suggestions and recommended changes for this guide specification are welcome and should be submitted as a Criteria Change Request (CCR) .

NOTE: These doors are an alternative to traditional horizontal steel sliding doors. Contact the NAVFAC Engineering Innovation and Criteria Office for more information.

The door system design needs to provide for alternate means of operating doors in the event of loss of power.

As of this writing, the fabric utilized in these doors does not comply with impact-resistance requirements on facilities in DoD "wind-borne debris regions" and do not meet the testing criteria of ASTM E1996/ASTM E1886 (Refer to UFC 3-310-01 Paragraph 2-4.6 for additional information).

SECTION 08 34 16.20 Page 4

Testing is underway by some manufacturers to find and develop vertical lift fabric door systems which meet these requirements.

When this specification is used for a fuel cell maintenance hangar, paint hangar, or corrosion control hangar the hazardous classification may impact electrical components of the vertical lift fabric door system - such as the electrical drive, limit switches, control panels, and other electrical devices. All electrical devices within the hazardous classification areas must be specified to be rated for the hazardous location where electrical equipment is installed.

To properly coordinate with this specification, the drawings must, at a minimum, indicate the following information:

1. Size and arrangement of doors including, if applicable, clearances in accordance with UFC 4-211-01 Paragraph 2.3 MINIMUM AIRCRAFT

MAINTENANCE BAY CLEARANCES.

2. Preferred location of mullions, mullion pits and mullion swing, as applicable.

3. Electrical and structural provisions and preferred locations for hoists, motors and control center.

4. Location and type of any required personnel doors and extent of any non-fabric flat panel door area(s).

5. Design wind velocity and appropriate design wind pressures based on the design wind velocity. See paragraph below entitled, WIND LOADS for more detailed requirements.

6. Anticipated, service level maximum vertical deflections (up and down) of the building structure from which the door system will be supported. Deflections should not include dead load - but should be indicative of the anticipated deflections that may be experienced during the life the door and building. Additionally, the structural engineer of record shall coordinate with manufacturers on supporting structure serviceability limitations and provide camber to anticipate deadloads including the weight of the door.
