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
6
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 preengineered manufacturer’s shop drawings
7
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
8
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
9
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
10
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 preengineered manufacturer
• Provide for and locate all collateral loads
•
•
•
•
•
•
Sprinklers
Basketball goals
Exhaust fans
Underhung equipment
Mechanical and Electrical systems
Ceilings
11
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
12

of the review process
14

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
16
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”
17
3. Modular Units and Modular Construction
(G.S. 115C-521) (G.S. Chapter 143)

Mobil/Modular Units

to be followed
• Taking bids for purchase

• HVAC units should be inspected, tuned and
balanced before occupancy
• This is especially true if modular units/buildings are being
relocated.
24
