Failure to do so may result in substantial fines in theevent of an OSHA inspection. Safe installation practicesmay be further defined and made mandatory by state orlocal ordinances.

Maintaining good housekeeping on the jobsite isrecognized as being important to both OSHA complianceand to successful job completion.

The Occupational Safety and Health Act (OSHA) haspromulgated many regulations applicable to theinstallation of this or any other wall system. Theseregulations, identified as Part 1926, Safety and HealthRegulations for Construction, are available from anygovernment bookstore. The objective of the OSHAstandards is to protect the worker from injury or illness.These OSHA regulations should be recognized as job siterequirements and be fully complied with.

If the erector cannot safely assemble the wall system inaccordance with these instructions, it is the responsibilityof the erector to stop the work and contact Bigbee SteelBuildings, Inc. to determine alternate assemblyprocedures.

The erector of the wall system is responsible for the safeexecution of this installation guide. These instructions areintended to describe the sequence and proper placementof parts. They are not intended to prescribecomprehensive safety procedures.

2.2 OSHA

2.1 Erector's Responsibilty2.0 SAFE WALL INSTALLATION

2.3. Handling Wall Materials in Strong WindsDo not attempt to move panels in strong winds. Windpressure can easily cause a man to lose balance and fall.Strong wind uplift on a panel can lift the weight of the mancarrying the panel.

Loose, wind borne panels are very dangerous and cancause severe injury and damage.

Secure stacks of panels with banding or tie-downs, sowind will not blow the panels around. Clamp individualunsecured panels to the wall structurals. Clamp or blockpanel bundles and accessory crates to prevent them frombecoming airborne.

2.4 Completed and Braced

2.5 Lateral Stability

Before starting wall installation, it must be confirmed thatthe structure is designed to accommodate the materialand erection loads as well as the appropriate live loadsand wind uplift loads.

It also must be determined that the structure is completeand structurally sound with all structural connections andbracing in place and secure.

The wall panels to the wall structural provides limitedlateral stability and diaphragm bracing to the wallstructural during erection. Before starting the wall

installation, confirm that the necessary roof & wall bracingand sag angles, strapping or bridging for structuralstability is in place and secured.

A spreader bar will be required for the longer panel cratesto assure correct sling spacing and uniform lifting. Thespreader bar must be large enough to handle themaximum panel bundle weight and length.

A forklift is handy for unloading and placing shorter paneland accessory crates.

Hoisting equipment is necessary to unload and positionthe panels and accessory crates for site storage andinstallation. The equipment must have sufficient capacityand reach to place the material where it is required forefficient installation.

Slings will be required to minimize panel damage. Therecommended slings are nylon straps of 6" minimumwidth and of sufficient length to accommodate the panelbundle girth.

It is imperative that any shortages or damage of thedelivered materials be noted at once and clearly markedon the bill of lading before signature of acceptance.Notify Bigbee Steel Buildings, Inc. immediately of anyconflicts. Bigbee Steel Buildings, Inc. will not beresponsible for shortages or damages unless they arenoted on the bill of lading.

In the case of packaged components (fasteners andsealants, etc.), the quantities are marked on theircontainer and should be checked against the bill ofmaterials. Bigbee Steel Buildings, Inc. must be notifiedof any shortages or concealed damage within 15 daysof delivery.

Your material is carefully inspected and crated beforeleaving the plant and accepted by the transportationcompany as being complete and in satisfactory condition.It is the carrier's responsibility to deliver the shipmentintact. It is the consignee's responsibility to inspect theshipment for damages and shortages when it is delivered.

Conducting a material inventory at the time of delivery isessential. By conducting the materials inventory, theerector is able to identify any material shortage ordamage and avoid stopping installation later because ofsuch shortage or damage.

3.2 Equipment For Unloading and Lifting

3.1 Material Inventory3.0 RECEIVING & HANDLING WALL MATERIALS

3.3 Lifting Panel BundlesUnder normal conditions, panel crates less than 35' longcan be lifted with two slings spaced at third points. Panelcrates longer than 35' can be lifted with three slingslocated at quarter points using a spreader bar to achievecorrect sling spacing for uniform lift.

Slings should be located under the cross boards. Loadsshould always be checked for secure hook-up, proper

balance, and lift clearance. Tag lines should be used ifnecessary to control the load during lifting, especially ifoperating in the wind.

Panel crates less than 25' long may be lifted with a forkliftonly if the forks are spread at least 5' apart and blockingis used to prevent panel damage by the forks.

3.0 RECEIVING & HANDLING WALL MATERIALS3.4 Field Storage of Wall Materials

Upon acceptance of the shipment, the customer or hisrepresentative is responsible for proper handling storageand security of the wall materials. Bigbee Steel Buildings,Inc. is not liable for damage or loss of materials at the jobsite.

The panel bundles should be stored on the job site inaccordance with the following recommendations:

A. Store panels in a protected area, out of standingwater and drifting snow, etc.

B. Elevate panels with blocking to allow air circulationunder the bundle.

C. Slope panels for drainage of moisture from thepanels.

D. As necessary, cover panels with waterproof tarp,allowing for air circulation (do not wrap tarp under panelcrate or restrict air movement).

E. Inspect panels daily for moisture accumulation.

F. If panel bundles contain moisture, the panels shouldbe dried and re-stacked. Use care in re-stacking to avoiddamage to panels.

G. Opened or re-stacked panel bundles should besecured to prevent wind damage.

When moving panel bundles, extreme caution should betaken to prevent damage to the panel edges. Uncratedpanels should be supported at each end and at 8' spaces.

Trim and accessories should be stored in a secure areaand protected from damage, weather, and theft.Fasteners, sealants, closures, etc. should be stored outof the weather and protected from contamination.

Panel Bundle

Blocking

Stack blocking so bundleis sloped for drainage

The jaws of the vice grips must be padded to preventdamage to the panel surface. The clamps should beuniformly spaced, no more than 10' apart and the handlines must be pulled in unison so that uneven lifting doesnot buckle the panel. Be sure the clamps are tight on thepanel and the line is secure to prevent dropping thepanel, which can result in personal injury and propertydamage.

To lift individual panels, lift one side of the panel by theseam letting it hang naturally to prevent buckling. Pick-uppoints should NOT be more than 10' apart. Do notpick-up panels by the ends only, or in a flat position.

If the individual panels are to be lifted by hand line, thecommon method is to use the vice grip "C" clamps.Position the clamps on the flat of the panel, as close aspossible to one edge so the panel is lifted in a verticalposition.

4.0 WALL INSTALLATION BASICS4.1 Proper Tools

Before starting paneling, be sure that the properequipment and tools are on hand. The tools must be ingood operating condition and operators should adhere tosafety precautions at all times.

Improperly operating tools, too few tools, inadequatepower source, or other equipment deficiencies slow downthe installation process. The cost of inefficient working isusually greater than the cost of providing goodequipment.

This list should not be interpreted as a limitation to yourinventory of installation equipment.

The following tools and equipment should be consideredfor efficient installation of the Bigbee Steel Buildings, Inc.panels. Actual tools and equipment required may varydue to variations in building type and construction.

4.2 Equipment List

Screw Guns -- Designed for use with self-drilling screwsSocket Extensions -- 3" extension for screw gun HexSocket Heads -- 1/4", 5/16" and 3/8", magneticDrill Motor -- 1/4" capacityDrill Bits -- AssortmentSheet Metal Cutter -- or power shears or nibbler"C" Clamps -- vise grip type with swivel padsPop Rivet Tool -- 1/8" capacitySheet Metal Shears -- left and right cutHack Saw -- with metal cutting blade

Combination SquareCrimping PliersSteel Measuring Tape -- 12', 50', 100'Nylon String LinesChalk Line (NO red chalk)BroomsMarking Pen (NO lead pencils)Caulk Guns -- for 1/10 gallon sealant tubesPower Source and Extension Cords -- capable ofhandling the total equipment requirements, without powerdrop due to extension cord length.

B. CONTAMINATIONTo assure proper adhesion and sealing, the sealant musthave complete contact with adjoining surfaces andachieve 30% compression. Contaminants such as water,oil, dirt and dust prevent such contact. The panel andflashing surfaces must be dry and thoroughly cleaned ofall contaminants. Before applying tape sealant, thesealant should be checked for contaminants. If thesealant surfaces are contaminated, it must not be used.

During cool weather, condensation or light mist canaccumulate on the panel and flashing surface and not beeasily noticed. It is recommended that sealants alwaysbe kept under protective cover and that the panel andflashing surfaces be wiped dry immediately beforeinstallation.

Tape sealant is provided with a protective paper toreduce contamination. Incomplete removal of theprotective paper will prevent the sealant's adhesion to thepanel or flashing surfaces. Always check that theprotective paper is completely removed. Do not removethe protective paper until immediately before the panel orflashing is installed over the sealant.

A. TEMPERATURE EFFECTSTemperature extremes must be considered duringinstallation of the wall due to the sensitivity of sealants.The recommended installation temperature range is 20° Fto 120° F. At colder temperatures, the sealant stiffensresulting in loss of adhesion and compressibility. Athotter temperatures, the sealant becomes too soft forpractical handling. On cold but sunny days, the panel'ssurface may become warm enough to accept theapplication of a heated sealant even though the airtemperature is below 20° F.

When overnight temperatures fall below freezing, thesealant should be stored in a heated room so it will bewarm enough to use the following day. On hot days, thesealant cartons should be stored off the roof in a cool andshaded area. While on the roof, sealant rolls should bekept shaded until actual use.

In very cold weather, it is recommended that thefasteners be tightened slowly and only tight enough thatthe sealant is in full contact with the panel or flashing.Then on the next sunny day, complete the tighteningprocess after the sun warms the panel and flashingsurfaces.

4.3 Sealants

During cold weather, the fasteners must be tightenedslowly to allow the sealant time to compress. If thefasteners are tightened too fast, the fastener may stripout before the sealant compresses adequately, or thepanel or flash may deform in the immediate area of thefastener, leaving the rest of the sealant insufficientlycompressed.

C. COMPRESSIONTo assure proper adhesion and seal, the tape sealantmust be compressed between the panel and flashingsurfaces with firm and uniform pressure. In most cases,the required pressure is applied by the clamping action ofscrews pulling the adjoining surfaces together. However,the tape sealant's resistance to pressure becomesgreater in cold weather.

4.4 FastenersA. SCREW GUNUse torque control and variable speed screw guns fordriving self-drilling screws. 2000-2500 RPM screw gunspeeds are necessary to attain efficient drilling speeds.High tool amperage (4 to 7 AMP) is required to achievethe proper torque for proper seating and to secure thefastener.

B. SOCKETSUse good quality magnetic sockets. Good fitting socketsreduce wobble and stripping of the screw heads,especially the alloy and capped heads. They alsominimize objectionable paint chipping and scuffing oncolored screws and minimize damage to the protectivecoating on unpainted screws.

Magnetic sockets collect drill shavings, which will build upand eventually prevent the socket from seating properlyon the screw heads. One method of removing the drillshavings is to roll up a ball of tape sealant and push thesocket into the sealant.

When the socket is removed from the sealant, most of thedrill shavings will remain embedded in the sealantthereby cleaning the socket. This process should berepeated as often as needed to keep the socket clear ofdrill shavings.

C. INSTALLATIONBefore starting the screw, the materials to be joined mustbe pressed together with hand pressure. The pressuremust be maintained until the screw has drilled through allthe materials and the threads have engaged.

Most self-drilling screws require 20 pounds of pressure tomaintain the drilling action and to start the thread cuttingaction. Also, applying such pressure before starting thescrew gun will usually prevent tip walking or wandering.

If too little pressure is applied, the drill point may not cutinto the metal and the point will heat up and become dull.If the pressure is too heavy, the bottom material may bedeflected away, causing a standoff condition, or the drilltip may be broken or splits. Screws must be heldperpendicular to the panel or flashing surface duringstarting and driving.

For proper seating of the fastener-sealing washer, thepanel or flashing surface must be clean and drill shavingsmust be removed from under washers before seating.The fastener must be driven perpendicular to the panelsurface so that the washer can seat level without warpingor cupping.

Do not over drive screws. Over driving can strip thethreads and/or damage the sealing washer. Use screwgun with torque control set to function properly for thecombination of fastener size, hole size and materialthickness.

The fastener should be driven tight enough to uniformlycompress the washer but not so tight that the washersplits or rolls out from under it's metal dome. Therecommended procedure is to tighten the fastener untilthe sealing washer just starts to visually bulge from underthe metal dome.

As a good installation practice, all installers should carryapproved oversized screws. Upon stripping or breaking ascrew, the screw must be immediately removed andreplaced with the appropriate oversized screw. Do notdefer the screw replacement to be remembered and fixedlater, or to be found by the clean-up crew. The majorityof such screws will be overlooked until the customercomplains of leakage.

4.0 WALL INSTALLATION BASICS4.5 Field Cutting Panels and Flashing

When field cutting complex shapes, it is usually easier tocut out a 1" wide strip using both left and right handshears. The 1" cutout provides clearance to smoothly cutthe flats and the clearance to work the shears aroundtight corners.

When making repetitive cuts (such as cutting panels at ahip condition) it is recommended that a template be madefrom a piece of drop-off panel or flash to provide fast andaccurate marking of the field cut. When using panelmaterial for the template, cut off the top portion of thepanel ribs so that the template is easily laid onto the panelbeing marked.

C. MARKING PANELSAvoid marking the panels for cutting, etc., in a mannerthat will leave visible markings stains, etc., on the finishedsurface. Use chalk or felt tip ink markers. Do not usegraphite (lead) pencils on unpainted panel surfaces, thegraphite can cause rusting of the surface.

A. ABRASIVE SAW PROBLEMSAbrasive saws (circular saws with friction disks) are notrecommended for cutting panels or flashing. Abrasivesaws create high heat that may burn away the protectivecoating from the panel edge, causing the edge to rust.

Also, abrasive saw dust contains fine, hot steel particles,which accumulate on panel and flashing surfaces wherethey rust and can cause staining and rusting of thosesurfaces.

Rust caused by abrasive saw damage or abrasive dustparticles can be excluded from warranty claims.

B. SHEARING METHODSIt is recommended that panels and flashing be cut withshears to provide a clean, undamaged cut. On shear cutedges, the protective coating extends to the edge of thecut and is often wiped over the edge to further protect thebase metal. Whenever possible, fit the material so thatthe factory cut edge is exposed and the field cut edge iscovered.

Caution: Failure to maintain panel coverage widthwithin the specified tolerance can cause faulty panelseams which can result in a reduction in wallperformance.

The panels must be held to the width dimension of thepanel as designated on the erection drawings within a1/8" width tolerance per panel. The accumulatedcoverage (start panel to finish panel) tolerance isdetermined by the ability to keep the panels parallel andto correctly fit and assemble the finish corner condition.

Although the Bigbee Steel Buildings, Inc. wall system isdesigned so it can be installed in either direction (left toright or right to left), panel side laps should always beorientated away from the main traffic area's line of sightand away from the prevailing wind direction if possible.Check the erection drawings to determine if a specificsheeting direction is required.

The recommended installation sequence is to completeeach panel run from base to eave before starting the nextpanel run. This sequence will help ensure straight runsand allow the insulation to be installed immediately aheadof each panel run.

During installation considerations must be made formaintaining panel modularity. By maintaining panelmodularity, the panel side lap can be properly assembled,the proper coverage can be obtained, etc.

5.2 Layout & Checking for CoverageAfter the start panel is secured and engaged with the nextpanel, the start panel seam will be the reference line forchecking accumulated panel coverage.

Panel coverage is always checked at the base, eave andend splices so that non-vertical seam (or dogleg)conditions can be detected and corrected before theybecome objectionable. The coverage check should bedone with a measuring tape held taut and measured tothe same side of the seam and always parallel to thebase to prevent any measuring error.

Every four to six panel runs should be checked for panelmodularity. This will assure that the panels aremaintaining a straight line and proper coverage is beingmaintained. If the panels are off module, they should becorrected by equal adjustments of the next four to sixpanel runs.

Although the above stated coverage tolerance will providefor reasonable ease of installation and water tightness,such visible conditions as non-vertical panel seams,dogleg of the panel seam at the end splices andnon-vertical finish panel width, may be objectionable andshould be confirmed with the customer before continuingwall installation.

5.3 Appearance Considerations *

* Oil-Canning is a natural occurrence in metalpanels that does not affect the finish orstructural integrity of the panel and is thereforeNOT a cause for rejection.

8.0 WALL INSTALLATION DETAILS8.1 GENERAL

The following details provide graphic illustration of thewall assembly steps. The purpose is to instruct theerector in correct and efficient assembly of the wallsystem.

Because of the many variations in conditions, it isimportant that you review the job to identify and isolatethe specific installation details required for your job.

Review the erection drawings for differences with thesedetails. If differences exist, the erection drawings haveprecedence.

These details are arranged in a step-by-step sequence.Following this sequence ensures correct assembly andensures that the part to be worked on will be readilyaccessible for the next assembly step.

Do not shortcut these assembly steps without carefulconsideration of the possibility of incorrect or omittedassembly and the resulting corrective rework.

To help ensure weathertightness, the details emphasizeproper fit-up, sealing and fastening. It is most importantthat only the specified sealants and fasteners be used foreach condition and that they be installed correctly asshown on these details and the erection drawings.

Be sure that these critical instructions are reviewed oftenand the wall assembly is checked at each assembly step.

This view shows the wall system oriented for a left-to-rightsheeting direction. For right-to-left sheeting, reverse theparts orientation.

The details in this section will show the installation of thebase trim, corner angle, door cap trim, door trim, and thefirst run of insulation. These are parts that must beinstalled before the wall panel installation can begin.

Installation of the building wall panels are generally donebefore the roof. Before starting the wall panel installation,make sure that the eave struts and girts are straight andlevel. To align the girts, cut temporary wood blocking tothe proper length and install between the girts.

Blocking can be moved from bay to bay which will reducethe number of pieces required. Normally, one line ofblocking at each bay will be sufficient.

Refer to the erection drawings to determine the specificinsulation required for the project. In all cases refer to theinsulation manufacturer's instructions for proper insulationinstallation and vapor seal assembly. This detail showsfiberglass blanket insulation, which is the most commonlyused insulation for metal building walls.

The leading edge of each insulation run should extend

approx. 12" beyond the leading edge of the wall panel.This will allow for easy assembly of the vapor barrier sealbetween insulation runs.

Use double-faced tape along the backside of the eavestrut, corner angle, base angle and outside tabs at eachsupport member to hold the insulation in place until thewall panel is installed.

NOTE: Wall panels that will be subjected to driftingsnow must have sidelap sealant installed.

BigbeeRib II wall panel sidelaps are designed so that thepanel can be install from right to left or left to right.So for the best appearance the wall panels should beerected so that sidelaps are away from the main trafficarea's line of sight.

Refer to the erection drawings and shipping list (Bill ofMaterials) for the correct panel length for the starting run.
