DIY Vs Contractor Choosing Metal Building Construction
Are you planning to construct a durable metal building but unsure about the best construction approach? Whether you're considering a hands-on DIY project or professional assistance, this guide explores three primary construction methods to help you make an informed decision.
Before beginning your metal building project, you'll need to decide who will execute the construction. Here are the three main options:
- DIY (Do It Yourself) : Complete control over the entire construction process
- Owner-Builder (Acting as General Contractor) : You manage the project while coordinating subcontractors
- General Contractor : Hiring professionals to handle all aspects of construction
- General Contractor (GC) : Oversees all project aspects including planning, budgeting, subcontractor coordination, quality control, and safety
- Subcontractor : Specialized tradespeople handling specific aspects like electrical or concrete work
- Steel Erector : Professionals with specialized skills in assembling steel structures, particularly crucial for large projects
Constructing a metal building yourself is indeed possible. For structures under 3,000 square feet (such as 30x40 or 40x60 metal building kits), DIY may be feasible if you have relevant experience. Larger projects typically require professional crews with cranes and specialized equipment.
- Cost Savings : Potential savings of $4-$8 per square foot on labor costs
- Time Investment : Significant personal time commitment required
- Personal Satisfaction : The pride of completing a major project yourself
Metal building kits come with detailed instructions and numbered components - similar to assembling large-scale building blocks.
The foundation is the most critical first step, recommended to be handled by professionals regardless of your construction approach. After foundation completion:
- Install vertical columns or pre-assembled main frames
- Install frame rafters (if not using pre-assembled frames)
- Install secondary framing (wall and roof purlins)
- Complete gable end framing
- Install doors and windows
- Install wall panels and insulation
- Install roof panels and insulation
- Add trim and flashing
- Install gutters, downspouts, and porches (if included)
- Torque wrenches for high-strength bolts
- Impact drills
- Load binders
- Lifting equipment (cranes, forklifts, or tractors depending on project size)
A typical 30x40 foot steel building requires a four-person crew working for 3-6 days. Safety equipment including hard hats, gloves, and eye protection is mandatory.
- Failing to obtain proper building permits
- Inadequate site preparation
- Not following installation instructions precisely
- Modifying pre-cut metal components
- Compromising safety protocols
- Poor project planning leading to delays
As an owner-builder, you assume the general contractor role, handling project management, subcontractor coordination, permits, and inspections. The primary advantage is saving the 10-20% fee typically charged by general contractors.
This approach requires significant time investment and construction knowledge to effectively manage subcontractors and troubleshoot issues. Strong organizational and communication skills are essential for success.
Experienced general contractors handle all aspects of your project, including:
- Subcontractor hiring and management
- Permit acquisition
- Schedule coordination
- Quality control
- Problem resolution
While adding 10-20% to project costs, professional GCs provide valuable expertise, ensure code compliance, and typically deliver projects on time and within budget.
When considering a general contractor, evaluate your ability to:
- Identify and manage qualified subcontractors
- Understand local building codes
- Recognize and address construction issues
- Comply with OSHA safety standards
- Negotiate with subcontractors
- Develop efficient project timelines
