1.6 MAINTENANCE

Provide maintenance and cleaning instructions for fabric canopy. Provide instructions for periodic re-tensioning (if required).

PART 2 PRODUCTS

2.1 SYSTEM DESCRIPTION

Pre-engineered framed fabric aircraft-type structures in size (each) as follows:

SECTION 13 31 33.00 22 Page 3 01/29/26

a. Overall exterior dimensions are as follows: 60 feet wide x 60 feet long with 30 feet - 6 inches exterior center height. Minimum interior clear dimensions are as follows: 56 feet wide with 26 feet interior clear center height. Minimum interior vertical clearance at the sidewall: 18 feet. Include with each structure four aluminum blast shields, 4 feet - 8 inches by 4 feet - 8 inches by 3/16 inch thick, fastened to the underside of the structure.

Structures include anchored tubular steel chord truss frame with a tensioned laminated fabric cover with a polyester scrim.

Any proposed deviations from the size indicated above are required to meet all airfield and airfraft clearance requirements.

2.1.1 Design Requirements

Design canopy structure(s) to resist wind load and seismic criteria as indicated on Structural drawings in accordance with ICC IBC and ASCE 7 requirements for Components and Cladding.

Provide pre-engineered framed fabric structures designed by a Professional Structural Engineer with a minimum of ten (10) years in the design and construction of framed fabric structures of the type specified herein.

2.2 STEEL STRUCTURES AND FRAMEWORK

2.2.1 Anchor System

Use Epoxy Adhesive anchors for existing concrete foundations (if occurring). New concrete foundations (where required) to be reinforced concrete designed to resist uplift forces. Provide 60,000 psi reinforcing steel per ASTM A615/A615M , Grade 60, and placed in accordance with ACI Detailing Manuals. Provide 3,000 psi minimum concrete mix in compliance with ACI 318 .

The intent is to anchor structures to concrete apron pavement, provide details of anchorages and how joints in apron will be accommodated. Also provide calculations demonstrating adequacy of concrete pavement to support loads.

2.2.2 Tubular Steel Trusses and Connections

Use tubular steel trusses for main framing. Fabricate tubing from ASTM A500/A500M , Grade B steel and hot-dip galvanized conforming to

ASTM A123/A123M .

Provide structural bolts that conform to ASTM A325. Provide all bolts with lock washers or locking nuts. Hot-dip galvanize all hardware conforming to ASTM A153/A153M .

Support trusses with rows of lateral x-bracing that connect at each truss with welded tabs.

Provide side and roof cables to provide additional strength to the frame system. Provide side cables with high visibility protection sleeves with reflective tape.

Provide Lightning Protection System in accordance with Specification Section 26 41 00 LIGHTNING PROTECTION SYSTEM, including air terminals, wiring, and ground rods in the each corner and middle of each side of each sunshade. Interconnect all ground rods with copper bonding conductors.

Interconnect all air terminals with copper bonding conductors and provide copper down conductors to connect to the ground rods. Do not depend on the structural steel to provide the electrical path. Design to facilitate replacement of canvas without affecting the lightning protection system.

2.5 LIGHTING

Provide Lighting inside the fabric structure in accordance with Specification Section 26 51 00 INTERIOR LIGHTING. Provide LED luminaires suitable for wet locations. Provide lighting color temp of 5100 CCR.

Lighting system must provide approximately even illumination of 25 footcandles at 3 feet above finished floor. Locate luminaires to avoid aircraft exhaust and blast shields.

PART 3 EXECUTION

3.1 INSTALLATION
