1 017/03/3 1/8 1.0 PURPOSE This specification describes the minimum requirements for Vertical Lift Doors. The latest standards, codes and regulations apply to all other requirements not specifically mentioned. In case of a conflict Vale will furnish a written interpretation..0 DRAWINGS The following drawings form part of this specification: B Vertical Lift Operated Doors Plans, Elevations and Details 3.0 GENERAL 3.1 SHOP DRAWINGS Submit shop drawings in accordance with Vale Specification SPEC Include schedule identifying each unit, with door marks and numbers relating to numbering on drawings and door schedule if any. The drawings will clearly show thickness of materials, construction details, attachments and reinforcing for hardware and other pertinent information. For power operated doors the above will also include electrical schematic drawings. Indicate mortises, reinforcements, anchorages, locations of exposed fasteners, openings (glazed, paneled or louvered) and arrangement of standard hardware. Units will not be ordered until the respective drawings have been approved. Verify all dimensions with job conditions before fabricating. Submit shop drawings well in advance of required fabrication to avoid construction delay. 3. DELIVERY AND STORAGE Deliver, store and handle units so as to prevent twisting, warping and damage. Do not remove units from crates of other protective covering until ready for installation. Supply and install hardware in accordance with the approved shop drawings. 3.3 DESIGN CRITERIA Design vertical lift door curtain and assembly to withstand the wind load as per the Building code. A minimum design wind load of 0 psf within door opening area, unless noted

2 017/03/3 /8 higher on the project drawings or higher value is calculated as per the Building Code. The door design shall be such that the jambs, weight box, guides and drive mechanism form a column required to carry and transfer the entire weight of the door and counterbalancing mechanism down to the floor. At the same time, transferring lintel wind load to the jambs. All roller chain sprockets shall be heavy duty, all steel type. Roller chains and cables shall have a safety factor of 7: MATERIALS Vertical lift doors to be industrial quality single or multi-leaf type, (see contract job drawings for type), each leaf operating on its individual vertical part of guides, and counterweights shall be balanced. All mounting hardware, operators, counter-weights and other necessary hardware to be supplied by the door manufacturer. Where required, welding must be concealed as much as possible. All welded joints to be ground smooth. All welding must conform to the latest CSA specifications using arc, mig and or spot welding for distortion free finished product. 4.1 DOOR LEAVES Each leaf to be constructed of structural steel channel frame, reinforced at approximately 4'-0 maximum centers faced on exterior surface with 16 gauge, "paint grip" galvanized steel, insulated and covered on inside with 0 gauge minimum "paint grip" galvanized steel sheet. 4. GLASS OPENINGS - VISION LITES Openings for glass to be 18" wide x 9" high x 1/4" thick polished wire glass. 4.3 GUIDES All leaves to ride in angle guides, guides mounted on 1 gauge minimum steel plate reinforced with " x " x 3/16" angles at 4'-0 vertical centers. Guide assembly to be mounted on 1/4" thick base plate for anchoring to the floor. Heavy duty spreader I beam joining guides at top. The weight box must have full height removable cover for easy access to weights and for future repairs.

3 017/03/3 3/8 4.4 COUNTERBALANCING MECHANISM Positive friction free drive achieved by use of machined cable sheaves and steel sprockets mounted on solid cold rolled steel cross-header shaft. Shaft to ride on heavy duty, regreaseable, self-aligning flange bearings mounted on heavy drive housing. Bottom driving blade must be connected to counterweight by roller chains running over steel sprockets. All other blades to be connected to individual counterweight by galvanized aircraft cables running over machined idler sheaves. Each door blade must be provided with cable or roller chain adjustable tensioning which will ensure that when bottom blade will rise, picking up the second blade and succeeding blades, the door shall open effortlessly. For maximum safety, horizontal weatherstripping must be made using full width combination steel and neoprene astragal. Rubber weatherstripping alone will not be permitted. This will make it impossible, in case of cable breakage, for the top blade to drop below the bottom blade. For additional safety, the top blade must be supplied with steel pick-up bumpers equipped with rubber silencers. 4.5 SAFETY MECHANISM Door must be equipped with failsafe device sufficient to withstand the free-fall of the door system, by means of safety dogs, chain driven on door bottom section. 4.6 WEATHERSTRIPPING Provide 1/4" foam rubber pad on door stopper angles for each angle guide. Use vinyl sealing gaskets for meeting edges of door leaves and Lintel closure. Install "brush type weatherseal" vertically on door guides to give a complete perimeter weatherseal. 4.7 FIRE RATING Fire-rated doors shall be provided for those openings requiring fire protection and temperature rise ratings, in accordance with the Building Code or as specified on the project drawings. Such products shall be listed for conformance with CAN4-S104. All fire-rated doors shall bear the label of, and be listed by a nationally recognized testing agency having a factory inspection service. Labeling shall be in accordance with NFPA 80, the listing authority's policies and label materials, and shall identify the manufacturer. Firerated doors shall be constructed as listed for labeling in the Follow-Up Service Procedures/Factory Inspection Manuals issued by the listing agency to individual manufacturers.

4 017/03/3 4/8 5.0 INSULATION Door leaves must be fully insulated with " thick semi-rigid AF-530 glass fibre. 6.0 PAINTING Paint system to be in accordance with Standard SPEC Epoxy System for Steel Heavy Industrial and Underground and to include S.S.P.C.-SP7 Brush Blast.
