Section Site & Foundation Preparation A
PREPARATION OF SITE AND FOUNDATION 1. General Before the Mueller prefabricated steel building arrives, the site and foundation should be prepared. This includes leveling the terrain and constructing the foundation. Mueller buildings are typically designed to be placed on a permanent slab. A concrete contractor is highly recommended for this phase of the construction. 2. Procedural Steps A. Remove trees, debris, and other items from the building location. B.
SQUARING OF FOUNDATION For proper building erection, it is critical the foundation is square. The following examples are suggested to ensure square foundation.
ANCHOR BOLT SETTINGS It is extremely important that anchor bolts be placed accurately in accordance with the anchor bolt setting plan. All anchor bolts should be held in place with a template or similar means, so they will remain plumb and in the correct location during placing of the concrete. Check the concrete forms and anchor bolt locations prior to the pouring of the concrete. A final check should be made after the completion of the concrete work and prior to the steel erection.
ANCHOR BOLT SETTINGS Refer to your anchor bolt drawing for proper sizes and dimensions. Stake Template Form Board Anchor Bolts Anchor Bolt 11/2˝ 11/2˝ Foundation Sheet Ledge Note: Suggested protrusion is 2 1/2" of threads above concrete.
Section Building Delivery And Storage B
UNLOADING AND PREPARATION OF PARTS FOR ASSEMBLY The vehicle transporting your building parts must gain access to the building site from the adjacent highway or road. Such access should be studied and prepared in advance of arrival. All obstructions, overhead and otherwise, must be removed and the access route graveled or planked if the soil will not sustain the heavy wheel loads. A forklift or other type of power loader may be required to unload the truck and move the heavier parts to the proper locations.
UNLOADING, HANDLING, AND STORAGE OF MATERIALS Structure A great amount of time and trouble can be saved if the building parts are unloaded at the building site according to a pre-arranged plan. Proper location and handling of components will eliminate unnecessary handling. Blocking under the columns and rafters protects the splice plates and the slab from damage during the unloading process.
LOCATION OF BUILDING PARTS Place the parts around the foundation so they will be in the most convenient locations for installation. For example: place the end columns and rafters at the ends of the building and the mainframe columns and rafters at the sides. Place the bolts and nuts in a place where they will be accessible to the parts. You may want to screw the bolts and nuts together and place them with the corresponding parts. This will save time as you begin assembling the parts.
CARE AND HANDLING OF MUELLER SHEET METAL Delivery Mueller takes every precaution to ensure that material is delivered to the customer damage free and fully protected from the elements during shipment. When the material is delivered to the customer it then becomes the customer's responsibility to protect the material from the elements, possible theft, and other damage.
WALL AND ROOF PANELS Mueller’s wall and roof panels including color coated, galvalume, and galvanized provide excellent service under widely varied conditions. All unloading and erection personnel should fully understand that these panels are quality merchandise which merit cautious care in handling. Under no circumstances should panels be handled roughly. Packages of sheets should be lifted off the truck with extreme care taken to ensure that no damage occurs to ends of the sheets or to side ribs.
WALL AND ROOF PANELS (continued) Storage: It is recommended that sheets be stored under roof if at all possible. If sheets are to be stored outside, the following precautions should be observed: 1. The storage area should be reasonably level, and located so as to minimize handling. 2. When stored on bare ground, place a plastic ground cover under the bundles to minimize condensation on the sheets from ground moisture. 3.
Section Erection of Primary And Secondary Structural C
GENERAL INFORMATION Many methods and procedures are in use for erecting the structural portion of metal buildings. The techniques of raising frames vary from erecting small clear spans and endwall frames in units to erecting the larger clear spans and modular frames in sections. The erection methods used depend strictly on the type of building, the available equipment, the experience level of the crews, and the individual job conditions.
TOOLS AND EQUIPMENT REQUIRED The types of tools and equipment required in order to assemble and erect the building depend on the size of the building purchased. This part of the instruction manual lists the tools and equipment that are normally required for most buildings. You may wish to use more or less power equipment or different tools than are listed as the need dictates.
End wall door column (EWDC) Door header (DH) End wall interior column (EWIC) Beam end wall column (EWC) End wall girt (EWG) Base angle (BA) End wall extension Wide flange beam frame (MFR) Long lap Z-bar (LLZ) Eave strut / Eave purlin (ES) Z-bar wall girt (WG) Extension Cable bracing (BC) Rigid frame extension Rigid frame with straight column (MFR) Rigid frame extension with straight column Rigid frame with tapered column (MFR) Rigid frame with straight column & pipe interior column Typical b
RAISING RIGID FRAMES The intermediate or interior frames nearest the bearing endwall are usually erected first. This bay usually contains the diagonal bracing. The proper completion and plumbing of this first bay is extremely important to the successful completion of the building.
RAISING RIGID FRAMES (CONTINUED) After the columns have been erected, the ground-assembled rafter is hoisted into place and connected to the columns. The size of the rafter that can be safely handled depends on the equipment available and the experience of the erection foreman. Generally as many connections as possible are made on the ground. Flange braces loose bolted The flange brace should be bolted to the rafter prior to raising in order to save time.
RAISING RIGID FRAMES (CONTINUED) Lifting Cables And Spreader Bars In all instances the length of the lifting cables should be such that the angle between the rafter and the lifting cables is no less than 45 degrees. To reduce the severe compression stresses at the ridge of the rafters that are created by the angle of lifting cables, a spreader bar is recommended, which allows the lifting cables to be parallel to each other.
RAISING RIGID FRAMES (CONTINUED) Completing And Plumbing The First Bay After the first intermediate or interior frames have been set, Mueller, Inc. recommends that all purlins, girts, and eave struts be installed in the braced bay and the entire bay plumbed, aligned and braced before proceeding further. If the building is designed without cable bracing, the erector is responsible for providing temporary erection bracing.
RAISING RIGID FRAMES (CONTINUED) When the rafters consist of several roof beams, as in the case of wide buildings, a safe procedure of raising by sections and supporting the free end must be followed, regardless of the type of equipment available. In most instances the work proceeds from outside columns inward toward the peak until the entire frame is bolted into place. The same general procedures of erection apply to either clear span or multiple span frames.
ERECTING COLUMN AND BEAM ENDWALLS Column and beam endwalls of 50 feet or less in span may be raised into position and set on the anchor bolts as a unit. All rafters, column, girts (except outside endwall girts which connect to the sidewall girts), door headers, door jambs, clips, diagonal brace rods, etc. should be assembled on the ground with the bolts left finger tight. A spreader bar should be used to raise the endwall frame.
ERECTING THE REMAINING FRAMES & Eave struts The remaining frames are erected in like manner, initially with only a few purlins being installed in each bay working from one end of the building to the other. To lend overall rigidity to the structure, install flange braces to the purlins at specified locations. All purlin, girt and eave strut connection bolts are left loose so the entire skeleton framework can be plumbed without undue difficulty.
JOINTS NOT SUBJECT TO TENSION LOADS Joints not subject to tension loads need only be tightened to the snug tight condition, defined as the tightness attained by a few impacts of an impact wrench or the full effort of a man using an ordinary spud wrench. Joints Subject To Tension Loads Two tightening procedures are specified for A325 bolts in joints subject to tension loads, turn-ofthe-nut method and direct tension indicator.
ASSEMBLY OF BRACE CABLES 1. Assembly of brace cables: Note: Cable may have to be field cut to proper length. A. Insert grip through eyebolt. B. Begin wrapping the grip around the cable, matching the crossover marks. C. Continue until the lasts two wraps are left split the legs and apply separately. D. Duplicate this procedure on each end.
INSTALLATION OF WIND BRACING (CONTINUED) Assemble the next brace cable the same way and connect to the next column to form an “X” with the other cable. Column Cable Turnbuckle Eyebolt To square the building, measure the length of the diagonals and tighten or loosen the turnbuckle/ eye-bolt until the lengths are the same. Double-check by using a square at the corners. Brace each sidewall frame the same way so that you have an x-brace on each side.
INSTALLATION OF THE WIND BRACING Diagonal bracing in metal buildings is critical. They provide support for wind loads or other longitudinal loads, such as those created by an overhead crane in the completed structure. Many times additional temporary bracing is needed to stabilize the structure during erection. The erector should review this requirement, and the erector should provide any additional bracing.
INSTALLATION OF WIND BRACING (CONTINUED) Hillside Washer Installation Hex Nut Flat Washer Hillside Washer Note: Hillside washer installation similar at base. Note: Care should be taken not to over-tighten the wind bracing. Overtightening the bracing can cause premanent damage to the framing. www.muellerinc.
INSTALLATION OF WIND BRACING (CONTINUED) Occasionally the bracing in the wall of a building cannot be installed in the specified bay because of doors or other complications. Usually these can be moved to other bays without affecting the structural integrity of the building. However, before moving any wind bracing check with Mueller, Inc. Do not remove after building is erected.
Section Insulation D
WALL INSULATION Fiberglass blanket insulation is the most common type used, and these instructions pertain to this type only. One side of the blanket insulation should have a vapor barrier that must face the inside of the building regardless of whether the insulation is for heating or cooling. Fiberglass insulation to outside of building Vapor barrier to inside of building Wall Insulation Installation Cut the insulation to length allowing an additional 6” or more to facilitate handling.
WALL INSULATION (CONTINUED) The first run of wall insulation should be installed so that its forward edge is just ahead of the leading edge of the wall panel. This keeps the forward edge of the insulation ahead of the wall panel for joining the next blanket.
ROOF INSULATION Pre-cut roof insulation to reach from eave to eave allowing approximately 2 feet of additional length to facilitate handling. Hold insulation at one sidewall and roll out insulation across the purlins, vapor barrier to the inside of the building. Stretch the insulation to provide a tight and smooth inside surface. Note: Insulation has no load bearing strength. Maintain body weight on approved scaffold or walk boards. www.muellerinc.
ROOF INSULATION (CONTINUED) Double sided tape or contact adhesives can be used to hold insulation in place while the roof sheets are being installed. Trim excess insulation to the edge of the eave trim and cut fiberglass approximately 4 inches from end leaving only facing. Fold facing over end of blanket insulation to seal the end.
ROOF INSULATION (CONTINUED) Seal insulation sidelap joints by lapping 4” tab side. As on the walls, the general sequence is to install the roof sheets in conjunction with the insulation. First Roof Panel 4'-0" 1'-0" Blanket Insulation Double-sided Tape Eave Trim Eave Strut Note: The insulation sidelap must be lapped to prevent condensation and minimize temperature loss at laps. Warning! Wipe oil and other slippery substances from roof panels.

ALIGNING THE GIRTS Installation of the building walls is generally done before the roof. Before starting the wall installation, check to be sure that the eave strut and girts are straight and plumb. One method of aligning the girts is to cut temporary wood blocking to the proper length and install between the lines of girts. This blocking can be moved from bay to bay, which will reduce the number of pieces required. Normally, one line of blocking per bay will be sufficient.
SCREW ALIGNMENT Good alignment of the screws, especially on the wall panels, will give a professional appearance to the wall panel installation. One way this can be accomplished is by pre-drilling holes in the panels at identical locations. Up to 15 panels can be stacked together and drilled using a template panel. Use 1/8” or 5/32” diameter drill bit for panel to structural fasteners and a 1/4” diameter bit for the sidelap clearance holes.
SCREW ALIGNMENT (CONTINUED) The template panel should be laid out for the proper screw locations in accordance with the building erection drawings. Since pre-drilling will “hand” the panels, it will also be necessary to select the end of the building from which the paneling is to begin. Before drilling the template panel, it should be checked for proper hole locations against the building framework. Be sure there is no excessive deflection in the purlins and girts.
INSTALLATION OF WALL PANELS Adjoining panels are installed with the overlapping rib toward the last erected panel. Position panel to structural making sure that it is kept plumb and install fasteners at lapped rib. Check for proper coverage (3' center to center) and correct as necessary. Install remaining fasteners. ng eti ion e Sh rect Di Blanket Insulation Wood Blocking Steel Frame Line Wall Panel Wall Panel Note: Start first panel with major rib centered with endwall frame. www.muellerinc.
INSTALLATION OF WALL PANELS (CONTINUED) Backlapping the wall panels 1 foot or 2 foot is routinely done to match panel coverage with the building width and length. On the sidewall this is done with the last panel installed. On the endwall this is normally done near the center and will be marked on the erection drawings.

OPTIONAL SHEET LEDGE WITH EXISTING SLAB Wall Sheet (R-Panel Shown) Base Angle Base Flashing Note: Sheets must be at least two inches off the ground, or rust may occur. www.muellerinc.
FASTENER INSTALLATION Correct fastener installation is one of the most critical steps when installing roof panels. Drive the fastener in until it is tight and the washer is firmly seated. Do not overdrive fasteners: A slight extrusion of neoprene around the washer is a good visual tightness check. Always use the proper tool to install fasteners. A fastener driver (screw gun) with and RPM of 1700-2500 should be used for self-drilling screws.
SAFETY NOTE! CAUTION!!! PANELS MAY BE SLICK UNSECURED PANELS MAY SLIP IF STEPPED ON! Never step on a single unsecured roof panel, or a stack of roof panels laying unattached on the purlins. Secure each end of the panel with clamps or appropriate fasteners and place walk boards of adequate size and strength in the flat of any panels not fully secured to the purlins and supported by panels on each side.
PREPARING THE EAVE After installing the first run of insulation, prepare the eave for the first roof panel by applying sealant tape along the eave outside of the insulation and leaving release paper in place. Sealant must be applied in a straight line and without voids. Do not stretch the sealant. Use a knife to cut if necessary. Cut an inside closure strip as shown and place starter piece on top of the sealant (removing protective paper from the sealant only as required).
PREPARING THE EAVE (CONTINUED) Along the top of the closures that have been placed along the eave, apply a second run of sealant tape. Prior to removing paper backing, check and mark for proper alignment of the first roof panel. Continue sealant tape and closure run along eave in preparation for the next roof panel.
INSTALLATION OF FIRST ROOF PANEL Once the eave is prepared, the first roof panel may be installed. Check the erection drawings to determine the roof overhang at the eave. Set the roof panel in place over the inside closure (after removing the paper from the sealant tape) ensuring the major ribs of the panel nest properly with the inside closure. Align the center of the major rib of the panel edge with the edge of the endwall roofline.
INSTALLATION OF ROOF PANELS With the first panel run installed and secured, and sidelap sealant applied, the second panel run may be started. Prepare the eave with an inside closure and sealant tape as shown previously. Position the panel so the overlapping ribs will nest properly. Be sure to check for proper overhang and panel coverage. Lap screw the major ribs of the two panels together, and fasten panel to the purlins.

ROOF SHEETING SEQUENCE It is recommended that both sides of the ridge of a building be sheeted simultaneously. This will keep the insulation covered for the maximum amount of time and the panel ribs can be kept in proper alignment for the ridge panel. Check for proper coverage as the sheeting progresses. Note panel-sheeting sequence below. 11 10 12 7 8 4 2 9 5 6 3 1 Note: If slippery substances are present on the roof panels wipe them clean immediately to prevent slipping or falling.

SEALING THE SIDELAP Apply the sidelap sealant tape to the weather side edge of the lower panel’s major rib as shown. The sealant tape should only be applied to clean, dry surfaces. With the release paper in place, press firmly along the length of the sealant to ensure proper adhesion. In removing the protective paper from the sealant tape, care should be taken not to pull the sealant tape away from the panel. Install the adjoining panel positioning the overlapping rib with care.
SEALING THE EAVE Sealant tape location at the eave is critical. To ensure a weather tight seal, the sidelap sealant must extend down from the top of the rib to the sealant on the eave closure. The sealant extension must splice into the eave sealant tape.

SEALING THE ENDLAPS At the panel endlaps place a run of sealant tape across the full panel width ½" below the fastener line. The panel endlaps have a 12" minimum overlap located over a purlin as shown. Locate the fasteners 1” above the purlin web according to the fastener layout. 12" Lap Ridge Roof Fastener Roof Panel Purlin Web Sealant Tape Sealant Tape Eave Purlin Note: Do not step on panel endlaps until fully secure with fasteners. www.muellerinc.
PANEL ENDLAPS Apply sealant tape to far side of major rib to complete seal at panel lap.
INSTALLATION OF FINAL PANEL While backlapping the last roof panel (to match panel coverage with the building length) is routinely done, this installation method can compromise the integrity of the roof by trapping moisture between the panels. This moisture could, in time, create an environment conducive to rust and metal failure. Manufacturer recommends field cutting the final panel lengthwise to create the desired panel width necessary to finish off the building.

Section Trim F
FLASHING, GUTTER AND TRIM The correct installation of flashing, gutters, and trim cannot be overemphasized. The overall appearance of the finished building depends primarily on the quality of the installation of the flashing, gutters and trim. Keep all gutter and flashing lines straight. Make all bends sharp and neat. Be sure edges are not jagged, dented, crimped, or serrated. End joints and laps must be closely controlled.
PEAK SHEET RIDGE INSTALLATION Peak sheet ridge panels are to be installed as each side of the roof is sheeted. This will aid in keeping both sides of the roof aligned. After having installed a run of panels on each side of the roof, apply sealant to the panels as shown. Set die formed ridge panel in place and install lap and purlin fasteners. Apply sealant tape along the top of the leading rib to prepare for the next sidelap.
