SPECIFICATIONS FOR SINGLE SLOPE BUILDINGS

 

General

All buildings shall be as manufactured by Parkline, Inc., Winfield, WV or equal.

Each building shall be supplied complete with all necessary component parts, including drill in foundation anchors, to form a complete building system and all parts shall be new and free from all defects or imperfections.

The building width and length shall be measured from the outside of the building wall panels and the height of the building shall be the distance measured from the bottom surface of the base channel to the exterior juncture of the roof and sidewall panels.

The building supplier shall supply a complete set of building erection drawings showing a step-by-step construction sequence for the erection of the building. The erection drawings shall be prepared specifically for the building covered by these specifications showing the
location of all roof and wall accessories and the exact anchor bolt locations required for each accessory.

Design Criteria

All buildings shall be designed in accordance with the applicable sections of the latest edition of the AISC "Specifications for Structural Steel Buildings" and the AISI "Specification for the Design of Cold-Formed Steel Structural Members".

Each building shall be designed for the following loads, in addition to the stationary weight of the building. Reduction of loads due to tributary loaded areas will not be permitted.

1. The vertical Live Load of the building shall not less than pounds per square foot applied on the Horizontal projection of the roof.

2. The Ground Snow Load of the building shall not less than pounds per square foot applied on the Horizontal projection of the roof.
3. The horizontal Wind Load of the building shall be not be less than MPH and shall be distributed and applied in accordance with the
applicable edition of the "International Building Code" published by the International Code Council

All combining and distributing of auxiliary equipment loads imposed on the building system shall be done in accordance
with the applicable section of the 2000 edition of the "International Building Code" published by the International Code Council

Upon request, the selected building manufacturer shall provide the building purchaser with complete design certification signed and sealed by a registered professional engineer.

Roof Panel Design

Roof panels shall be supplied in a single continuous length from eave line to eave line or ridge line and shall be designed to tightly interlock so that no fasteners are required at intermediate points along the panel side laps.

Roof panels shall be 16" or 12" wide with a smooth surface between the interlocking side ribs. The interlocking ribs shall be a minimum 3" high, and shall be turned upward. All roof panels shall be factory punched for connection at the eave line of the building.

There shall be no fastener penetrations through the roof covering except at eave lines, ridge lines and roof accessory openings such as skylights and ventilators.

Finish Option 1
Roof panels shall be nominal ____ gauge galvanized steel conforming to ASTM A-653 specifications with the galvanized coating conforming to G90 (1.25 oz. commercial) standards. Minimum yield strength of the panel material shall be 50,000 PSI.

Roof panels shall receive a factory, roller applied, paint coating having an exterior coating thickness of 0.8 to 1.2 mils of dry film thickness.

The roof panel color coating shall carry a low fire hazard rating equal to a Class 1 material as defined by Factory Mutual. The Panel coating shall have achieved a Flame Spread Index of 0 and a Fuel Contributed Index of 5 or less when tested in accordance with ASTM E-84 test procedures.

The finish coat shall be a white siliconized polyester formulation that will meet the following performance standards after 10 years continuous exposure in "normal" atmospheric conditions not containing corrosive fumes such as chemicals or salt spray.

1. Panels shall show no evidence of blistering, peeling, or chipping.

2. Panels shall not show surface chalking in excess of the No. 4 rating D659 as established by the American Society of Testing Materials (ASTM).

3. Panels, after cleaning, shall not show color change in excess of 7 NBS units when measured in accordance with the ASTMD-2244 standard.

The above performance standards shall not apply where panels have been damaged by fire, radiation or other physical damage.

Finish Option 2
Roof panels shall be a nominal __ gauge steel coated on both sides with a coating of corrosion resistant aluminum-zinc alloy conforming to ASTM A 792 specification with the coating conforming to AZ55 (55%) standard by a continuous hot dipping process. Coating weight shall be a minimum of 0.50 oz. of aluminum-zinc alloy per square foot of coated sheet equivalent to about 0.8 mil thickness on each side.
Minimum yield strength of panel material shall be 50,000 PSI.

Wall Panel Design

Exterior wall panels of the building shall be a single continuous length from the base channel to the roof line of the building at the sidewalls and endwalls of the building except where interrupted by wall openings.

Wall panels shall be 16" wide with a 3" deep inward turned interlocking side rib. Wall panels shall contain two 3/4" deep by 3-1/8" wide fluted recesses, each starting 2-7/16" from the panel edge.

Wall panels shall be fastened internally to the base channel and eave cap of the building with 3/8" diameter electro-galvanized machine bolts placed within the panel interlock. The fastening system shall be designed so that no wall fasteners are exposed on the exterior surface of the walls.

Wall panels shall be nominal 24 gauge galvanized steel conforming to ASTM A-653 specifications with the galvanized coating conforming to G90 (1.25 oz. commercial) standards.

Minimum yield strength of panel material shall be 40,000 PSI. Panel material shall be embossed with a random pattern pebble embossure of approximately .007 - .008 depth.

All exterior surfaces of the galvanized steel wall covering and exterior trim shall receive a factory, roller applied, paint coating having an exterior coating thickness of 0.8 to 1.2 mils of dry film thickness. The finish coat for wall panels shall be a siliconized polyester formulation of one of the following Parkline colors: Twilight Blue, Desert tan, Laurel Green, Arctic White, Harvest Gold, Shell Gray, or Roman Bronze.

The wall panel color coating shall carry a low fire hazard rating equal to a Class 1 material as defined by Factory Mutual. The panel coating shall have achieved a Flame Spread Index of 0 and a Fuel Contributed Index of 5 or less when tested in accordance with ASTM E-84 test procedures.

Exterior color coatings shall meet the following performance standards after 10 years continuous exposure in normal atmospheric conditions not containing corrosive fumes such as chemical fumes or salt spray.

1. Panels shall show no evidence of blistering, peeling, or chipping.

2. Panels shall not show surface chalking in excess of the No. 8 rating D659 as established by the American Society of Testing Materials (ASTM).

3. Panels, after cleaning, shall not show color change in excess of five (5) NBS units when measured in accordance with the ASTMD-2244 standard.

The above performance standards shall not apply where panels have been damaged by fire, radiation or other physical damage.

Building Type

Each building shall have an interlocking panel roof system with a 1-1/2" pitch over the building width. Roof panels shall be attached to the wall cap through factory punched holes, with #14 corrosion resistant fasteners.

The roof system shall include a gutter and downspout system at the low sidewall, eave trim at the high sidewall, and matching rake trim at the building endwalls. All gutters and trim shall be galvanized steel prepainted Arctic White or Roman Bronze.

Transmission of horizontal wind loads across the building shall be made through the panel roof system and no separate roof or wall diagonal bracing shall be required.

Where required for proper transmission of lateral wind loads, structural frame wind bents shall be installed. Wind bents shall consist of a prime painted column and rafter bolted assembly of steel conforming to ASTM A-36 specifications.
