2 pre engineered buildings
2. Pre-Engineered Buildings
  • Definition
    • Typically a metal building with:
      • Light gauge metal standing seam roof panels
      • Steel purlins spanning between rigid frames
      • Light gauge metal wall cladding
    • Relatively flexible structure vs. conventionally steel framed building
      • Greater vertical and horizontal deflection
2 pre engineered buildings7
2. Pre-Engineered Buildings
  • General
    • May be purchased by local school boards as
      • Part of a new school project, addition or renovation
      • Stand-alone building project
    • Must be designed by NC licensed architect and/or engineer
    • Must be submitted to School Planning, DPI for review (G.S. 115C-521)
    • Superstructure designed by certified engineer and fabricated by a pre-engineered manufacturer as a complete system
      • Foundation system designed by an independent NC licensed structural engineer (engineer of record for the project)
      • Engineer of Record shall review and approve the pre-engineered manufacturer’s shop drawings
2 pre engineered buildings8
2. Pre-Engineered Buildings
  • School Planning will issue a Certificate of Review upon completion of the review and certification that the Engineer of Record has reviewed and approved the pre-engineered structural system
  • Project architect and engineer (Architect/Engineer of record) must be in the employment of the owner (G.S. 133-1)
    • Project designers cannot be employed by or have financial interest in manufacturers or suppliers of pre-engineered structures
2 pre engineered buildings9
2. Pre-Engineered Buildings
  • Advantages to Pre-Engineered Buildings
    • Fast erection
    • Low cost if manufacturer’s standard package/inventory and no add-ons
    • Open clear span
    • Easily expanded to match needs
  • Disadvantages
    • Marginal design, material and construction
    • Not energy efficient
    • Higher lifetime maintenance
    • Not durable for long term use (10-15 years max.)
    • May not include all construction/fit-up needed for intended building use
    • No secondary roof membrane
    • Usually no internally finished walls

Note: Pre-engineered buildings are generally not recommended for school

buildings except for non-instructional purposes: storage, maintenance

facility, etc

2 pre engineered buildings10
2. Pre-Engineered Buildings
  • Items to Consider:
    • All manufacturer’s drawings and design calculations
      • Affix Professional seal and signature of NC Licensed professional engineer
    • Roof system is very light. Check NC Code wind uplift attachment requirements for:
      • Roof deck
      • Roof structural members
      • Anchorage of steel columns and column piers/footings
    • Roof deck has little diaphragm capacity
      • Horizontal cross-bracing: on roof plane in both directions
    • Check roof structural members for surcharge load due to snow drifting
2 pre engineered buildings11
2. Pre-Engineered Buildings
  • Provide portal frames and/or cross bracing at side walls for proper building stabilization
  • Use pre-engineered frame at end walls and wind columns
    • System should easily accommodate future expansion
  • Horizontal ties or hairpins to resist outward thrust at base of rigid frame’s column
  • Check foundation system against forces calculated by pre-engineered manufacturer
  • Provide for and locate all collateral loads
    • Sprinklers
    • Basketball goals
    • Exhaust fans
    • Underhung equipment
    • Mechanical and Electrical systems
    • Ceilings
2 pre engineered buildings12
2. Pre-Engineered Buildings
  • Field modifications of structural members
    • Approved by pre-engineered building manufacturer
    • Carried out under supervision of engineer of record or a registered structural engineer.
  • Brick veneer and/or masonry wall enclosures
    • Specify limitation of horizontal deflection/lateral drift of the pre-engineered frames
  • We recommend the pre-engineered manufacturer be an AISC (American Institute of Steel Construction) certified steel fabricator

3. Modular Units and Modular Construction (G.S. 115C-521) (G.S. Chapter 143)
  • During on-site assembly multiple classroom and large buildings require particular attention to:
    • Life safety systems
    • Fire code provisions
    • Plumbing and electrical connections
  • HVAC units should be inspected, tuned and balanced before occupancy
    • This is especially true if modular units/buildings are being relocated.
