    A Step-by-Step Guide to Erecting a Metal Building

    The process of erecting steel buildings can seem tedious and confusing. But it doesn’t have to be! Here’s a step-by-step guide to assembling metal buildings:

    Step # 1: Setting the Foundation

    The foundation is the building block of erecting a metal building. To start setting the foundation, you’ll have to review the instructions relevant to bolting anchors. You’ll also have to ensure the slab of cement is entirely flat so that you can pinpoint the bolts.

    Step # 2: Constructing the Frame

    Constructing your metal building’s frame starts with the I-Beam columns and rafters. Since builder’s ‘pre-engineer’ steel buildings, meaning that all pieces are pre-cut, punched and welded.

    Step # 3: Adding Girts, Purlins, and Framed Openings

    After setting the main framework, you can start installing girts, framed openings, and purlins. This way, your steel building will enjoy better wall and roof support.

    Step # 4: Installing Roof and Walls

    Next, engineers will begin focusing on the insulation, roof sheetings, and walls. Builders screw sheeting into the frame with the help of fasteners. After installing the walls, you’ll focus on the roof panels and weather stripping.

    Step # 5: Enhancing Aesthetics

    When erecting steel buildings, you’ll have to trim, accessorize, and polish your metal building. Trimming your metal building will ensure your building looks aesthetic and finished. Last but not least, engineers will install additional doors, windows, and vents.

    Understanding the Steel Delivery and Erection Process

    The process of delivering and erecting steel components can be tedious. Steel fabrications must be meticulous to ensure the project runs smoothly:

    Preparation

    Steel erectors ensure that steel components, such as protective coatings, steel beams, etc., arrive ready for installation.

    Practice

    Steel fabricators conduct trial assembles to ensure each component fits together according to the original plan.

    Timing

    Receiving steel components at the right time and in the right location is integral to running a project smoothly. This way, engineers can avoid costly delays.

    Delivery

    Every component must reach the site with necessary clips, bolts, anchors, bracings, and other connection materials required for delivery.

    Installation

    Erection and installation of a steel building include four components:

    • Establishing foundations and ensuring they are a safe surface for steel erection
    • Placing components by using cranes, jacking, or lifting. Moreover, securing components and bracings with the help of bolt connections
    • Aligning the structure by checking the column base
    • Bolting-up to secure and impart rigidity

    Fabrication Services during Steel Erection

    Let’s discuss in-depth the process of fabricating steel erection:

    Steel Beams

    Beams include girts, purlins, and tubes and may require cutting and welding depending on the provided specifications. Typically, engineers attach beams to support steel structures using bolts or welds to ensure structural integrity. Moreover, builders ensure that columns have adequate lateral supports before attaching crane beams or girt.

    Purlins

    Purlins refer to robust roof framing members spanning parallel to building eaves. Moreover, they lie over rafters or walls and support the roof decking and sheeting. According to steel industry practices, engineering drawings and documentation include structural shapes representative designations. Remember that steel purlins include welding support to enhance strength.

    Joists

    Joists boast the strength to support the anticipated load. Typically, the fabrication and installation of framing members, especially joists, must meet stringent building code standards. Joists help ensure a safe and stable floor or ceiling system by limiting stress and deflection.

    Truss

    Trusses refer to various elements like beams to create a rigid structure. Engineers install steel trusses in metal buildings to ensure stable construction.

    Bridge

    Bridges are load-bearing superstructures and include corresponding elements forming triangular units. These elements may have tension or compression loads and help stabilize and support buildings.

    Steel Erection Best Practices

    According to BLS fatality data, steel erection is one of the most hazardous occupations. Steel erection includes metal buildings, high-rise structures, and signs. To ensure the safety of team members, builders must comply with the following safety practices:

    Best Practices for Sequencing

    Sequencing steel erection projects is crucial for a successful project. Engineers may refer to sequencing as divisions, zones, and areas. It’s always wise to consult a general contractor to identify which direction the steel construction project will head. After meeting with the general contractor, the erector should determine the size and divisions depending on the crane size. Steel erectors also request interior access. Moreover, if your project requires sequencing, you must meet with the fabricator to fabricate components according to the desired specifications. The general contractor, fabricator, and erector must be on the same page.

    Best Practices for Safety

    To ensure the safety of your employees, steel erectors must:

    • Develop a written safety and accident prevention guideline
    • Foster a culture to ensure the safety of team members on every step
    • Keep all equipment, tools, and machinery are in perfect shape
    • Make it mandatory to ensure a clean and well-organized site
    • Maintain a highly-trained and qualified ironworkers
    • Require 100% fall protection

    Best Practices for Structural Stability

    It includes:

    • Avoid placing construction loads on structural steel
    • Maintain the structural stability of steel buildings
    • Positioning and installing temporary bracing is essential to ensuring the strength of the structure
    • You may remove temporary bracing with the approval of a competent person

    Best Practices for Connections

    It includes:

    • A competent engineer determines the number of bolts required to ensure stability
    • Avoid using connections to the top flanges, joists, or beam attachments
    • During a steel erection, secure diagonal bracings with multiple bolts or wrench tight
    • If two beams frame from opposite sides, consider using a clipped connection
    • Size to support the weight of the construction process

    Best Practices for Bolting and Torquing

    It includes:

    • Avoid leaving unsecured objects at elevations
    • Follow stringent bolting instructions
    • Inspect bolt bags daily
    • Tie off impact wrench
    • Use retaining rings on impact sockets

    Identify Construction Needs

    Before investing in steel erections, it’s essential to identify the type of structure you’re planning to construct.

    Commercial structures have a unique design process. Moreover, industrial designs are dissimilar from residential facilities.

    Thus, all structures have unique planning, designing, and construction processes and require varying sizes, dimensions, and designs.

    Why Do Erectors Conduct Site Visits before Steel Erection?

    Before starting steel erection activities, engineers must conduct several site visits. Site visits serve several purposes, including confirming that a project matches your skillset.

    It’s also wise for steel erectors to consult a foreman running the project on on-site visits. During one, steel erectors tend to check:

    • If there are powerlines that need insulation or relocation
    • If there is adequate and easy access to the site
    • If the general contractor is on track to kick start the project
    • If the lay-down area is appropriately graded, well-drained, and firm
    • If masonry walls or stud bearing walls are ready
    • If roof opening dimensions are verified
    • If you need to remove objects in the place of a crane
    • If the project occurs in a flight path

    Site visits are essential to make the steel erection process smoother and prevent costly delays.

    Steel Erection Techniques

    Erecting steel components occur in two ways:

    • By Using Cranes- Lifts steel sections into place
    • By Using Mobile Elevating Work Platforms – Enables steel erectors and other builders to stand on its platform to access sections for bolting

    Let’s discuss both steelwork techniques in detail down below:

    Mobile Elevating Work Platforms

    MEWPs help access steelwork during erection, including bolting pieces and joining sections. Engineers may use mobile elevating work platforms on the ground or partly erected steelwork to install elements according to specified measurements. Before using a MEWP, it’s essential to identify how much weight it can support.

    Cranes

    Cranes may be of two types:

    Mobile Cranes

    These require little set-up time and no backup crane. Thus, mobile cranes are ideal for one-off, single-day commissions. Mobile cranes may be of the following types:

    • All-terrain Cranes
    • Crawler Cranes
    • Truck Mounted Cranes

    Non-Mobile Cranes

    It covers tower cranes that engineers can assemble on site. Moreover, tower cranes require a second to start functioning. However, remember that set-up and dismantling a tower crane can be costly.

    Why Choose Steel for Buildings?
