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 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 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 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 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 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 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
2. Pre-Engineered Buildings • Minimum Drawings for DPI, School Planning Section • Site plan showing relationship to: • Drives • Walks • Parking areas • Playfields • Utilities • Other buildings and site improvements • Property lines

Pre-Engineered Buildings • Foundation plans showing: • Slab on grade, slab control joints, tie rods/hairpins • Wind columns • Footings • Locations of lateral bracing, portal frames, etc • Structural design of framing system reviewed and approved by the engineer of record, other than a registered engineer in the employment of the manufacturer. • Pre-engineered shop drawings produced by the successful bidder: • Submit to DPI, School Planning for review • Final step in securing “Certification of Review” and completion of the review process
2. Pre-Engineered Buildings • Electrical system layout including: • Electrical service equipment • Lighting and power • Heating and/or cooling systems and ventilation • Plumbing Systems • Other architectural drawings as required to show: • Subdivision of space • Ceilings • Finishes • Doors • Windows, etc • Building Code summary and Life Safety Plan.
3. Modular Units and Modular Construction (G.S. 115C-521) (G.S. Chapter 143) • Mobile/Modular Buildings (freestanding, temporary, relocatable, single classroom or toilet units) • Bidding for purchase and installation laws similar to on-site, stick-built buildings • DPI, School Planning must review and approve plans
3. Modular Units and Modular Construction (G.S. 115C-521) (G.S. Chapter 143) • Modular Construction (as opposed to mobile/modular buildings) • Factory constructed modular components transported to the site • Entire sections of the building per-fabricated by mobile/modular manufacturer • Or smaller components: wall panels, roofing panels, etc. • Site already prepared with foundations and underground utilities • When the components are joined together the building is known as “modular construction” • Permanent building using pre-manufactured units • Even if technically possible to disassemble and move them • Modular Units assembled to form more than single classroom and/or requiring halls, toilets, etc. becomes permanent modular construction • Must comply with all general statutes related to construction • Must undergo complete state and local plan review • Sometimes referred to as “Mega-Modulars”
3. Modular Units and Modular Construction (G.S. 115C-521) (G.S. Chapter 143) • General Requirements for Freestanding Mobil/Modular Units • General Statutes for permanent, site-built structures to be followed • Taking bids for purchase • Formal or informal (depending on dollar value) • Must meet NC State Building Code requirements • Shop drawings: Approval Stamp from third party certification agency approved by the NC Department of Insurance (DOI) • Manufacturers must be approved for commercial construction by the Manufactured Building Section of DOI • Wind and other locale-specific code provisions must be met
