  6. 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

  7. 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

  8. 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

  9. 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

  10. 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

  11. 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

  12. 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

  13. 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

  14. 2. 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

  15. 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.

  16. 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

  17. 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”

  18. 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

  19. 3. Modular Units and Modular Construction (G.S. 115C-521) (G.S. Chapter 143) • Site-Specific Procedures (new and relocated Units) • Submit plans to School Planning for review and comment • Submit plans to local building inspector for approval and permitting • Plans shall indicate the following information: • Site Plan • Proposed location of units and any joining of multiple units • Distances to both staff and student toilets (200 ft. max.) • Building Code toilet facilities required for entire campus (may require modular toilet units)

  20. 3. Modular Units and Modular Construction (G.S. 115C-521) (G.S. Chapter 143) • Electric feeders, disconnects required by code • Plumbing service • Telephone, intercom, MATV, computer, etc. • Smooth surface walks from permanent buildings • Preferably covered • Meet handicap and ADA access requirements • Confirmation that units are constructed by DOI-approved manufacturer • Confirmation that units are certified by an approved third-party agency • Distances between units and from adjacent buildings

  21. 3. Modular Units and Modular Construction (G.S. 115C-521) (G.S. Chapter 143) • Foundation Plans • Location of masonry piers, size and footings • Tie down anchors • Footings shall rest on undisturbed soil or compacted fill • Minimum bearing capacity: 2000 psf • Bottom of footings minimum 12” below finished grade • Masonry piers laid in Type S mortar • May be dry-stacked if four sides coated with surface bonding cement and first course above footings set in bed of mortar • Ramp, steps and platform support legs • Provide footings for anchorage and support

  22. 3. Modular Units and Modular Construction (G.S. 115C-521) (G.S. Chapter 143) • Building Plans • Submit manufacturer’s architectural drawings • Showing compliance with NC Building Code • Accessibility provisions • Fire Code • Plumbing Code • Seal and signature of architect or engineer licensed in NC • Submit manufacturer’s plumbing, mechanical and electrical drawings bearing seal and signature of engineer licensed in NC

  23. 3. Modular Units and Modular Construction (G.S. 115C-521) (G.S. Chapter 143) • Other Considerations • Indicate other connections to permanent buildings • Though not required by Code, School Planning recommends: • Two-way intercom systems for safety • Computer networking • Telephone systems • MATV connections • All the above between all units and the permanent school structures

  24. 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.

  25. 4. Bleachers and Grandstands • For purposes of School Planning plan review, bleachers containing more than 5 rows are considered “permanent bleachers” and shall be reviewed by School Planning • Refer to our website for complete information in publication “Outdoor Bleachers” • Toilets: Within 400 ft. (maximum) of closest bleacher exit of that section of bleachers that toilet serves. • Comply with International Code Council (ICC 300-2007) requirements • Bleachers/Grandstands: located at least 10 ft. from adjacent property lines and buildings on the same lot • Comply with NC Building Code pertaining to accessible wheelchair seating and adjacent companion seating • Consult with the local building official early in the design process

  26. 4. Bleachers and Grandstands • Minimum drawings for bleacher/grandstand projects submitted for plan review: • Site plan showing playfields, drives, walks, parking, buildings, handicapped accessibility, property lines nearby, toilet facilities location and distance • Plan showing seating layout, aisles, ramps, steps, railings, guards, handicapped seating, dimensions to adjacent site features • Cross section showing seat/foot boards, railings/guards, foundations, concrete slab under footprint and structural elements • Include: riser height, row spacing, heights above grade, railing/guard heights • Provide enlarged details needed to describe project fully • Submit bleacher/grandstand shop drawings from successful bidder for final step in receipt of “Certificate of Review”
