1 NCPSMA 2010 Workshop Ridgecrest, NC “Required Facilities Plan Review by School Planning, DPI” Roger W. Ballard Consulting Architect School Planning Section School Support Division NC Department of Public Instruction Raleigh, NC Website:

2 2 OUTLINE “ Required Facilities Plan Review by School Planning, DPI” 1.Projects we review vs. Projects we don’t review 2.Pre-Engineered Buildings 3.Modular Units and Modular Construction 4.Bleachers / Grandstands 5.Athletic Out-Buildings / Other Small Projects 6.Contract/Construction Requirements for Public School Projects

3 3 1.Review of Projects by NC DPI School Planning Types of Projects We Review All New Construction, Renovations, Additions New athletic fields, bleachers, grandstands, press box, field houses, concession stands, dugouts, etc. New and Relocated Modular classroom units, ramps, steps, walkways, etc. including foundations Repair or replacement of structural systems New “dropped ceiling” in existing schools Replacing Windows or Doors Types of Projects We Do Not Review Bleachers containing 5 rows or less

4 4 Types of Projects We Review Demolition of existing school building Reroofing, over-roofing Relocating partitions; adding or deleting doors New Parking or Drives Technology system, security system, CCTV, etc. Improvements required by ADA Change-out of plumbing fixtures or change in type of fixtures New domestic water heating system, or upgrade Types of Projects We Do Not Review Demolition of buildings other than school buildings Roof patching or maintenance Any repair or maintenance, such as replacing flooring, patching walls, repainting, etc Repairing asphalt, potholes, etc. or resurfacing existing Upgrades of fire alarms, other existing systems Additions of simple ramps, etc or signage Plumbing replacements in-kind; replace faucets or other minor components Water heater replacement with same type and size

5 5 Types of Projects We Review New HVAC systems; new boilers; new chillers; changes in type of system; demo and replacement of air distribution system, etc. Upgrade or redesign HVAC control system New energy conservation system Complete replacement of exist HVAC or plumbing piping system; extension of existing system Major components of Power Distribution System New lighting systems (interior or exterior) Any new system affecting health, or welfare of students or personnel such as fire suppression, emergency power generation, etc Types of Projects We Do Not Review HVAC equipment replacement in- kind; small air handling or condensing units (5 ton or less); air diffusers and grills; fan, heaters, etc. Replacement of HVAC control components Repair of existing insulation Repair of existing piping Adding electrical outlets to existing systems Replacing or adding lighting fixtures to existing systems Replacement of isolated safety components with new elements meeting code and similar to those currently in service

6 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 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 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 ) Project designers cannot be employed by or have financial interest in manufacturers or suppliers of pre-engineered structures

9 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 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 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 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 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 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 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 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 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 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 19 3. Modular Units and Modular Construction (G.S. 115C-521) (G.S.

23 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 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 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”www.schoolclearinghouse.org Toilets: Within 400 ft.
