GENERAL INFORMATION

IMPORTANT: PLEASE READ CAREFULLY

Upon request, the Manufacturer of its Marketing Service may supply the name(s) of potential vendors that supply additional components and contractors to install concrete and erect the building components or to perform other work pertaining to the installation and erection of the building components. Manufacturer nor its Marketing Service have not investigated such vendors and contractors, and the provision of the name(s) does not constitute a recommendation of their skill or competence.

It is important to the buyer to rely solely on his own investigation when selecting a vendor or contractor. It is also important to check for comparisons and to be completely satisfied as to price, quality and timeliness as to the job. The Manufacturer and its Marketing Service or other affiliates are not, nor will be involved in construction; any representation or agreement between Dealer or Contractor and Buyer concerning delivery, construction, modifications or other items are between the parties thereto.

This manual is intended to provide buyers and their erectors with some recommended procedures for erecting their building components. However, Manufacturer is not liable for the quality of erection, safety procedures during erection, poor foundation design or construction, site preparation, site selection, including soil and drainage testing or the negligence of other parties.

Because of the wide variation throughout the country in loading and zoning requirements and environmental conditions (snow, wind, etc.), it is the responsibility of the builder or owner to make certain that his building conforms to all codes and is adequate to withstand local environmental conditions. When necessary, and upon specific request, the Building Manufacturer can engineer supply building components to meet special requirements, at moderate additional cost.

Before starting construction, we suggest that you read the erection procedure and thoroughly study the specific erection drawings marked for construction supplied with your building. This will allow you to plan the work properly and could avoid unnecessary delays during construction. You should also familiarize yourself with laws and regulations governing permitting, labor and employment, safety, material handling and disposal, and any other issues which may apply to your business.

Erection of these buildings, as all construction, can be very dangerous. Dealer and Buyer are responsible for all safety procedures, and should follow all appropriate for all safety procedures, and should follow all appropriate rules and regulations as well as standard industry safety procedures.

Corrections of minor misfits and a reasonable amount of cutting and reaming are considered a part of erection. Errors in fabrication which prevent the proper assembly and fitting of parts by moderate use of reaming, chipping, or cutting should be reported to the fabricator, so that he may either correct the error or approve the method of correction to be used.

FOUNDATIONS

General Information

Foundation design and construction are the most important steps in the building process, and the contractor or owner is ultimately responsible for the quality of the foundation. It must be noted that improper or inadequate foundation construction will severely limit the building performance and could lead to costly repair or rebuilding.

It is essential that the building foundation meet certain design assumptions and load conditions. For this reason, all building foundations should be designed by a local soils engineer, in accordance with local city, county and state codes.

Certain basic guidelines and considerations for foundation design are outlined on the anchor bolt drawings furnished by the company. Careful consideration of the following notes will be helpful in completing the foundation.

General Foundation Notes

The top of the floor or foundation must be square, level and smooth, and the anchor bolts accurately set to a tolerance of (PLUS OR MINUS) 1/16" on dimensions within the group spacing for an individual member. All other dimensions shall be within (PLUS OR MINUS) 1/8".
All embedded structural steel (including reinforcing bars, wire mesh and anchor bolts) will not be supplied by the building Manufacturer.
All anchor bolts should be 3/4" ANCHOR BOLTS in order to conform to manufacturer's design assumptions.
Refer to Anchor Bolt Plans for specific details and dimensions.

page 2

SQUARING THE FORM WITH STRING LINES

Foundation Layout

Regardless of the type of foundation that is used and its specific configuration, the foundation outline should be carefully and accurately laid out before any excavation is made. Whenever possible, a transit or similar means should be used to lay out the foundation perimeter this will insure accurate placement of corner measures and, in turn, insure a square foundation.

Your building is manufactured to close tolerances and therefore requires a square and level foundation. Several methods may be used to achieve the proper foundation

NOTE: Wind can blow the strings sideways, or the strings might sag while putting up forms. Support the string lines to prevent this if necessary

Another method of assuring a square foundation is the Right Triangle Method. Use the dimensions of the two sides of the right triangle A and B as shown in the chart and adjust the string lines to obtain the proper length for C. Check square of all four corners

Dimension A	Dimension B	Dimension C
15'	20'	25'
18'	24'	30'
21'	28'	35'
24'	32'	40'
27'	36'	45'
30'	40'	50'

FOUNDATION FORMS AND ANCHOR BOLTS

FORMING

After the building foundation has been designed, careful planning should be exercised in the construction of its forms. To the right is an example of the panel notch forming necessary for the accommodation of the building paneling.

It is extremely important that all Anchor Bolts be placed accurately in accordance with the Anchor Bolt Plan. Before pouring concrete, study carefully the following general notes describing size, type and position of Anchor Bolts.

Setting Anchor Bolts

Use 3/4" Anchor Bolts or equivalent. Not supplied by building manufacturer.
The threaded portion of the bolt should be a minimum of 2-1/2". Anchor Bolts should project 2" minimum above surface of concrete. (Refer to Anchor Bolt Setting Plan.)
All Anchor Bolts should be held in place with a template (see right) or similar means in order to remain plumb during the pouring of the concrete. All templates should be prepared in advance so that they can be quickly nailed into place. Be sure to clean machine oil from bolts before placing them in template. The bolt threads should be covered or protected from concrete during pouring.
Air Relief Holes should be drilled in the template to allow trapped air to escape. When floating concrete, vibrate until wet concrete appears at top of air relief holes.

MATERIAL LAYOUT

After the building material is unloaded, it should be placed in and around the building site near the place where it will be used. This is referred to as “Shaking Out.” While each job will vary according to the size or site conditions, the layout below typifies an arrangement which offers conveniences for assembly. Columns and roof beams are laid in position for rising. Girts, Purlins, Columns and Braces are divided according to the requirements of each bay. Each part is numbered for quick identification.

Carefully check these numbers against shipping lists to insure that the correct parts and quantities have been received.

The layout of materials illustrated below is provided as an aid to identify and locate building parts. Once the erection procedure has begun, however, erection crews and machinery must have access to that portion of the building which is under construction.

CAUTION:

WATER SENSITIVE MATERIALS

(Bare or Coated Galvanized, Galvalume, Aluminized, Aluminum, etc.) These panels or boxes must be stored in a dry, warm atmosphere. If this material is allowed to get wet or moisture is permitted to form (condensation) between the materials, serious deterioration of the finish will occur.

FOR YOUR OWN PROTECTION

If these materials get wet, separate and dry all materials immediately.

RIGID FRAME BUILDING: OVERALL FRAMING

The illustration below is a three-bay structure of typical Rigid Frame clear span design, with top-mounted “Z” purlins, and sidewall girts. Endwall girts are flush mounted.

However, since the manufacturer provides various building designs for its customers, all details shown represent typical buildings and connections only, and variations may exist.

PLEASE NOTE: This erection booklet must be used in conjunction with the erection drawings marked “For Construction” supplied with your building materials.

Building overview

page 7B picture

Listed below is a list of check points to use when plumbing all wall columns. Using a carpenter’s level will show if they are not plumb.

Uneven concrete at the base of columns is the most common culprit. Sometimes dirt, pebbles, or debris is hidden beneath the base plate. Simply removing the column and cleaning away the debris will plumb the column. Other times the concrete has set up unevenly in which case metal shimming is required. Torque anchor bolts tight after shim is in place. Check for plumb. Repeat process with thicker or thinner shim if required.
Improperly set anchor bolts that are too far apart or too close together will cause unlevel frames. Minor shimming at the haunch and peak will correct this.

page 7

ERECTING THE FRAMING

Begin erection of the building starting with an interior Bay, preferably one with no window or door openings (an uninterrupted bay) and one with permanent wind bracing.

STEP 11

Final structural framing inspection

Conduct final Inspection on all structural bolts

Be sure that all connections have proper amount of bolts installed, and proper torque

Check wall for plumbness and make necessary adjustments using shims where required.

Check all framed openings for square and plumb

Apply touch up primer to areas where field modifications were performed.

NOTE - Turn of the nut method:

There shall first be enough bolts brought to a snug tight condition to insure that the parts of the joint are brought into good contact with each other. Snug tight is defined as tightness at the low impact setting of an impact wrench or the full effect of a man using an ordinary spud wrench. All nuts should then be turned an additional 1/3 of a turn to produce minimum allowed tension.

page 13

INSULATION

NOTE: The insulation outlined on this page is a general representation of most typical insulations and their installation. However, individual manufacturers may vary slightly in their insulation types and application procedures.

If insulation for the building is desired, longer screws may be needed. The standard 1" long self drilling screws (S.D.S) will suffice for blanket insulation up to 3-1/2" thick. Optional 1-1/2" long self drilling screws (S.D.S) will be needed for blanket insulation 4" to 6" thick. For insulation types other than fiberglass blanket type, special screws will be needed. Please consult with insulation supplier on this matter.

SHEETING INSTALLATION

General Sheeting Instructions

Identify the sidewall sheets, the endwall sheets, and roof sheets. Prearrange them in a convenient location near portion of the building being worked on. Be certain to use the correct length of sheet before fastening it to the building.
Be sure all sheets are secured or protected from the wind at all times
Install the sidewall sheets first, beginning on the side away from the primary visual source, such as the rear wall of the building. This will produce the best appearance, because the sheeting laps will be on the side away from the viewer.

Do not use roll caulking (mastic sealant) on laps when sheeting sidewalls

Install the endwall panels next, again concealing the laps away from the front view of building.

Do not use roll caulking (mastic sealant) on laps when sheeting endwalls

The roof sheets are installed last. Start these so that the laps are away from the prevailing wind. It is standard among metal buildings to use roll caulking (mastic sealant) on laps when sheeting the roof.
Use self-tapping screws (S.T.S) at all locations where screws go through only sheeting or trim. Use self-drilling screws (S.D.S) at all locations where they go through both sheeting and purlins and girts.
For effective results, it is vital that an adjustable torque screw gun with 2,500 RPM be used for the self-drilling screws supplied with your building. Failure to use a 2,500 RPM gun speed will result in broken drill points on these screws.

NOTE: Occasionally the rubber washer may spin out from under the self drilling screw head; replace it with a new self drilling screw. (S.D.S) If this becomes frequent, reduce the torque on the screw gun or replace it as needed.

NOTE: Occasionally the screw hole of a self tapping screw (S.T.S) may become oversized, use a #17 x 3/4” self tapping screw (S.T.S) to correct this. If this becomes frequent, reduce the torque on the screw gun or replace it as needed.

WALL SHEETING INSTALLATION

Step 1

Diagram for identifying the wall panels, the proper seam lap, and the proper screw placement when fastening the sheets to the building.


NOTE: Wall sheeting does not require role caulking (mastic sealant) and is NOT supplied for wall sheeting

DISCLAIMER FOR ARCHITECTURAL PANEL

The architectural style panel will occasionally reflect a wavy appearance. This is referred to in the industry as “oil canning” and this condition can magnify when panels are placed over blanket insulation. Oil canning is a characteristic of a flat surfaced panel and can be found throughout the industry. Therefore, when ordering an architectural panel, you must realize this may or may not occur and is not a manufacturing error. It appears more pronounced in darker colors. The waviness will be warranted as far as certification and integrity. However panels will not be warranted for oil canning and/or appearance. Please be aware that this may occur and advise your customer (for your own protection) before ordering.

page 18

Step 2

Pre-drilling the high rib lap for self-tapping screws (S.T.S)

Prearrange the sheeting in stacks near the area convenient to where they will be attached to the building. Measure the lengths of the sheets and check them with the area to be covered.

Make certain that the sheets at one end of the stack are lined up; this end should be set at the base of the building. Secure the stack firmly while drilling to prevent misalignment.

On the exterior lapping rib, mark the pilot hole to be pre-drilled at 18” spaces, start 2 ¾” in from the bottom end of the sheets. Use 1/8” diameter drill bit. Remember drill pilot holes only this side of the sheet.

Do not drill holes in siphon side of sheets

Stop 18” hole pattern 12” from top end of sheeting due to eave and gable flashing in later steps.

step 2 picture

page 19

Step 3

Begin sheeting the sidewalls first. Plan the lap so that it is not visible from the front of the building. Start the first sheet at corners with center of high rib in line with edge of steel line as shown. See next page for center line starting point for first sheet.

it is very important that you use a level to plumb the wall sheets while holding them to place by hand. When plumb, run the first two screws through the girt to hold the sheet in place.

STEP 7

The numbers shown on the roof sheeting below indicate the order of which they are to be applied. Note the ladder detail showing easy access while on the roof and the ridge cap detail for buildings with steep roof pitches.

CAUTION: NEVER walk on or step on High-rib part of sheet. Always walk on lower part of sheeting where it is fastened to the roof purlins.

CAUTION: If not using a sheeting ladder, always lay down a 2"x8"x10' or larger board support to walk on roof sheeting between purlins.

Notice: Install your ridge cap panel as the roof sheets are installed. Do not place all your roof sheets, then go back and place your ridge caps later.
