6. Exterior membrane will be fabricated for post-installation tensioning in both primary grid directions to prevent wear and abrasion; draped or loose-laid membrane installation is not acceptable.

7. Horizontal tension shall be maintained mechanically with horizontal purlins or spreaders that require no ongoing maintenance.

8. Exterior membrane will white or off-white.

9. In order to provide the introduction of natural light for daytime use, a continuous section of highly translucent white architectural membrane (skylight) shall be incorporated into the membrane along the peak of the structure. To minimize internal solar gain in the structure, the balance of the exterior architectural membrane shall be white or off-white in color and complete with a blackout layer.

10. Exterior membrane shall, upon completion, provide a continuous weather-tight enclosure.

11. Upon installation and tensioning of the exterior membrane it will be smooth and wrinkle- free and shall remain so under anticipated thermal and live-load conditions.

12. Membrane shall be repairable without the need to dismantle any portion of the structural framing.

13. In order to minimize future costs of repair and replacement of localized membrane damage, design the main structure to be modular in design consisting of individual membrane panels which do not exceed 15 ft in width on the main center modules.

14. Membrane shall be attached to framing that allows for ventilation fans or HVAC duct penetrations.

15. Slope the top surfaces of door canopies to shed snow and rain away from front of doors and away from the main structure such that all mating surfaces are watertight.

C. General Design Requirements

1. Design the main structure to be clear span, with no visible poles or columns inboard of the perimeter framing.

2. Design the main structure to be clear span, with no guy-ropes or cables extending or attaching perpendicular or at angles to the perimeter walls. Design the structure so that there are no structural purlins, cables or other obstructions to flow of water or sliding snow on the exterior membrane.
