SPECIFICATIONS FOR ARCH TYPE BUILDING SYSTEMS This section covers the design, material, fabrication, shipment and erection of arch-based building systems. All material, erection and field work included and excluded shall be in accordance with the "Code of Standard Practice" of the building construction industry.
DESCRIPTION
All the various models of buildings listed below utilize the basic bolted arch panel concept to form spans of various shapes. The pre-punched panel bolted construction can be utilized for permanent structures or be easily dismantled for reassembly with virtually no damage to the members. This portability is an added feature not normally encountered in the pre-engineered building field.
BUILDING SIZE
Building sizes range from 10' wide to 70' wide. Lengths are unlimited, based on
2' for all models. Peak heights and sidewall clearances vary for different model types and cover a wide range of combinations.
BUILDING TYPES
P
Series A
straight sided building with a pitched roof.
Ranging in size from 14 ft. to 30 ft. wide with
unlimited lengths. Q
Series A
straight sided building with a pitched roof.
Ranging in size from 16
ft. to 50 ft
wide with unlimited lengths.
S
Series
A straight sided, multiple radius clear span arch system. Standard sizes range from 20' wide to 60' wide, with straight sides and varying center heights.
ARCH STRUCTURES
All arch structures utilize our standard 2'W X 10'L corrugated prepunched panels as the basis of the design. Panels are cold formed to various radii as required and bolted together to achieve the desired span. Panels are gang punched to ensure uniformity of manufacture and ease of assembly.
ENDWALL SYSTEMS
All endwalls are designed using our standard 18" center 3 1/4" deep corrugated, prepunched panels to form various endwall arrangements as required. By altering the pattern of panels, any size opening can be achieved to accommodate roll-up, overhead, swing or sliding door systems.
BUILDING LOADING
General Basic design loads shall include live, snow, wind and earthquake (if applicable) in addition to dead load. All loading shall be in accordance with the governing building code as prescribed by local building authorities.
Snow and Wind Load Design snow and wind load shall be based on the specified ground snow load and wind pressure respectively. Distribution of loading over the building envelope shall be in accordance with the applicable governing building codes for the location involved.
Seismic Loads If applicable, the effect of dynamic loads must be considered in combination with other loads.
DESIGNS & PLANS
Plans and Specifications The manufacturer shall submit plans and specifications in sufficient detail to establish the design of the structure under consideration, including but not necessarily limited to, all loading conditions, material grades and geometry of the panel section.
Design Certification upon request, the manufacturer shall furnish a letter of design certification signed and sealed by a registered professional engineer.
MATERIALS
Materials shall be new and shall meet or exceed the mechanical and physical properties required by the design and the fabrication process.
MATERIAL CERTIFICATION
Upon request the manufacturer shall furnish a letter certifying that current inventory materials meet or exceed the mechanical and physical requirements of the design and fabrication process. Laboratory or mill test reports of current inventory materials shall be available for inspection if required.
FABRICATION
Fabrication tolerances shall not exceed those recommended by the governing building codes.
ARCH SYSTEM MATERIALS
Basic arch panel structures are available in the following material:
Galvalume
.027" to .066" AZ180 Galvalume steel (Heavy Commercial Coating with 30 Year Warranty) passivated with regular mill finish.
FASTENERS
Fastener location and spacing shall be in accordance with manufacturer's standards for the roof (arch) and wall panels. Basic structural fasteners are as follows: Indented Hex Washer Head Machine Screws, Organic Coating, Assembled with Neoprene Washers
5/16 - 18 tpi X 3/4"
5/16 - 18 tpi X 1"
Square Machine Screw Nuts, Organic Coating
5/16 - 18 tpi
SEALANT
Manufacturer shall provide, when requested, quality metal building tape sealant for all roof seams and joints. Sealant is a butyl rubber compound used to seal panels against air, dirt, ice and water. Material is compatible with most plastics, foams, rubber and other metal building components.
TRIM & FLASHING
Special manufactured standard double angle flashing system is utilized at all endwall to roof transitions. Flashing is made from heavy gauge steel to provide some structural stability as well as finishing features.
ACCESSORIES
Manufacturer provides a complete array of standard accessory items available for all structure types.
Personnel
Doors
Construction - Pre-hung 3' X 7' Pre-assembled walk in door suitable for
emergency exit (Fire Escape).
Sliding Doors
Top-hung heavy-duty panel construction, with 14 gauge framing and 22 gauge corrugated door panels. Doors are equipped with pull handles, heavy-duty ball bearing rollers, interlocking edge, bottom seals, latch and lock device.
Hangar Doors
Manufacturer has a full range of standard double track top hung sliding hangar doors. Construction is as standard sliding doors, and leafs are on a double track system to allow for partial opening. Sizes range from 30' to 80' in width – in heights of
10' to 20'
Sectional Overhead Doors and Roll Up
Doors
Framed openings shall be all steel heavy-duty bolted construction. Type of door, hardware required and glazing shall be furnished, installed and painted by others.
Skylights, Door Lights, Wall
Lights
Manufacturer has a wide variety of fiberglass panels formed to the shape of the basic building components. Material is a quality 12 oz., 16 oz., or 24 oz. fiberglass panel designed to install as a replacement for standard steel sections for ease of erection.
Ventilators
Continuous circular gravity type 12" diameter ventilator or 12" diameter turbine ventilators utilizing heavy duty ball bearing type shafts for quiet long lasting service.
Roof and Wall Insulation
Arch type structures are compatible with all conventional insulation methods – spray on, fiberglass rolls or rigid foam.
WARRANTIES
Manufacturer's Warranty shall warrant the following:
1. All buildings are designed in accordance with the local governing building code to withstand the published wind and snow loadings when provided by the seller to the manufacturer.
2. All materials will be free of defect in material and workmanship.
SHIPPING
All arch structures have unique compact stacking capability due to the nesting of the standard panel components. This stacking feature greatly reduces the bulk found in normal building construction and reduces freight costs.
ERECTION
The manufacturer supplies detailed comprehensive erection guides and blueprints for all building models. These erection guides contain valuable information to minimize construction problems and speed up installation.
