Overview

General understanding of the 2010 Florida Building Code changes that effect the design and construction of educational facilities.

What fiscal challenges are in the changes

and how important are the changes.

Code Administration

Relocatable structures shall comply with local flood hazard area requirements,

Manufactures should be permitted to complete all buildings designed and approved prior to effective data of the new code, provided a clear signed contract is in place.

Permits are required for all hurricane protection

construction or alterations to a structure.

Code Administration Submittal of construction drawings and specs for

ALL impact resistance protection coverings or systems are required.

Code extends the inspection process to all

installations of impact resistance covering systems.

Code allows photocopies of approved DBPR

manufactured building plans can be submitted to local building departments in lieu of signed and sealed plans. Section 553.37(6), Florida Statutes.

Special Occupancy

Code references will change “community” college to “Florida” college and add a definition for Florida college.

Deletes duplicate occupancy capacity

requirements found in Chapter 10, Florida Building Code, from Section 423.18 Assembly occupancies as follows:

Special Occupancy

Section 423.18 - Assembly occupancies – Occupancy egress shall be in accordance

with Table 1004.1.1, Maximum Floor Area per Occupant, except as follows:

Dressing Rooms at 20 nsf/person

Special Occupancy

Gymnasium. The number of fixed and telescopic bench-type bleacher seats plus the main court area at 15 gsf/person, plus locker rooms at 5 nsf/person.

Classrooms and labs. If spaces are combined with folding partitions, the capacity and exiting shall be based on the capacity of all the spaces joined.

Small Group Areas in Media Centers, 5 nsf/person. Note: This section has been renumbered and sections

deleted from the text.

Special Occupancy EHPA’s shall be designed for wind loads in accordance

with ASCE 7. Minimum design loads for buildings and other structures, Category III (essential buildings). Openings shall withstand the impact of wind-borne missile debris in accordance with the impact and cyclic loading criteria of ASTM E-1886, ASTM E-1996 and SBC/SSTD 12-99.

The threshold for day-labor projects and when licensed

contractor are required to bid on capital improvement projects from $200K to $300K .

The Code adds an exemption for fire sprinkler systems

for existing educational occupancy - unless 50% of the aggregate area of the building is being remodeled.

Special Occupancy

Section 428 – Manufactured Buildings

Deletes reference to “third party” agency. (maintains consistency with Rule 9B-1, Florida Administrative Code)

All sub-systems are subject to inspections. (mechanical, electrical, and plumbing)

Clarifies the expiration date of approved manufactured

building plans upon effective date of new Code.(3/15/12) Exception allows for buildings under a signed

contract to be completed, construction shall start within 6 months of execution of the contract.

Special Occupancy Section 428 – Manufactured Buildings (continued)

Deletes language of “newly” constructed factory-built

schools adopted in Rule 9B-1, of the Florida Administrative Code, and clarifies that code required inspections for factory-built schools can be preformed by an approved DBPR agency.

Deletes language adopted in Rule 9B-1, regarding

recertification of previously approved manufactured buildings.

Code clarifies that a DBPR approved agency can

perform inspections on new factory-built schools. (Existing factory-built schools are covered in Chapter 5 of SREF.)

Special Occupancy

The IBC and the FBC revises Chapter 30 to merge with the Florida Fire Prevention Code. This is to update the Florida Elevator Safety Code to be consistent with the industry standards.

Code requires water irrigation systems on public school

district and Florida College properties to be equipped with soil moisture sensors.

Code requires that all air-moving equipment located

outside, on walls or roof top units shall meet the hurricane impact requirements and be self protected.

Special Occupancy

Code clarifies the fan control requirement. Designers must now correct their designs to omit the fan shut down from manual activation.

Code requires a permanently attached serial number

data plate for elevator cars. A building serving a swimming pool facility does not

require additional sanitary fixtures.

Code requires that all educational facilities in flood hazard areas shall comply with ASCE 24.

Highlights from the code:

Building Performance Freeboard for the occupancy of the facility could be between one to three feet above base flood elevation. Fill is required to be stable under flooding conditions. Flood openings to allow for the automatic entry and exit of floodwaters. Openings must be certified by a registered design professional. Stairs and ramps shall be designed and constructed to resist flood loads and to minize transfer of flood loads to the foundation or to break away without causing damage.

In V Zones and Coastal A Zones:

• Structures shall be supported on piles, columns or shear walls.

• Walls designed to breakaway shall not produce debris capable of damaging structures.

• Mech., heating, ventilation and A/C elements shall be located on the landward side of the structure. Flood-Damage Resistant Materials: • Flood-Damage Resistant Materials shall be used below the lowest floor elevation including freeboard.

• Structural steel exposed to the salt elements shall be hot- dipped galvanized after fabrication, other metals components shall be stainless steel or hot-dipped galvanized. Other areas of consideration: • Utilities and service equipment

• Site considerations for the facility

Structural Code indicates for buildings in flood hazard

areas, the elevation below which flood damage-resistant materials such as interior, finishes, trim, and decorative materials shall be as required by IBC.

Code retained the Florida specific language as it

relates to termite inspections.

Code up-dates ASCE 7 to the 2010 edition of FBC and introduces the new ultimate design wind speed maps.

Structural

Chapter 2, Definitions, Defines local “floodplain management

ordinance” where local communities will adopt FIRMs and higher standards for National Flood Insurance Program (NFIP) Community Rating System. FBC requested statutory authority so that local higher standards do not sunset every three years.

Structural Manufactured soffit material and systems shall

be labeled per requirements of IBC. Resulted from the hurricane season of 2004.

Code establishes manufactures installation

criteria for interchangeable components. Code specifies that manufactured soffits will be tested at 1.5 times design pressures, as required for windows and impact resistance coverings. This establishes a factor of safety for testing.

Structural

The exposure “C” with regards to uplift load at the roof-to-wall connection. Uplift loads shall be increased by 20%.

A new table created to show where all flood

provisions are located in the I-Codes, Table 1612.1, Cross References Defining Flood Resistant Provisions of the Florida Building Code.

(This table covers building, residential building, existing, mechanical, and plumbing in the Florida Codes).

Structural

Glass railings located in the wind borne debris regions changes from safety glass to laminated glass.

Louvers that protect intake & exhaust ventilation ducts not assumed to be opened and thirty feet above grade shall meet AMCA 540 for large missile impact resistance.

Code adds Section 1805, damp proofing and

waterproofing to buildings and structures located in HVWZ.

Structural Code reduces the concentrated load on purlins

from 300# to 200#. This reduction only applies to purlins.

Welders shall be qualified under the appropriate procedures of AWS code for the appropriate task being performed.

The language of exterior insulated glass units

will be moved to the ‘general’ section (2411.1) and will make the language applicable to ‘all’ glazed fenestration products.

Structural

Modification to code due to the adoption of the Manual of Steel Construction, 2005, Thirteenth edition.

Code requires termite protection for multiple types of foam plastics installed on the exterior face or under interior and exterior foundation walls and slabs below grade. The clearance above grade and exposed earth shall be at least 6”.

Code omits requirements for special inspections of compacted fill. (special inspection provisions in Ch. 17 have been deleted from the Code.)

Structural

Code provides for an effective method of ventilating crawl spaces and will allow a Florida Design Professional to design an unvented crawl space.

Code enhance the Unit Skylight definition

to include Tubular Day lighting Devices (TDD).

Mechanical Louvers that protect air-intake openings in structures

located in hurricane-prone regions shall comply with AMCA 550-08, Test Method for High Velocity Wind Driven Rain Resistance Louvers.

Mechanical Section 603, Duct Construction and

Installation. Due to overlaps in code criteria and formatting issues of the section, a new Table 603, Duct System Construction and Sealing, has been introduced. The new table format shows all duct sealing and mechanical attachment criteria at once, making code requirements for duct construction and installation clearer.

Mechanical New IMC language for “ducts connecting to a

furnace shall have a clearance to combustibles in accordance with furnace manufacturer’s installation instructions”.

Duct work shall not be installed in or within 4” of the earth, except where such ducts comply with Section 603.8. (This is a change from 6” previously).

Code promotes life safety in boiler rooms and limits carbon monoxide levels to a maximum of 50ppm, per OSHA guidelines.

Electrical

Code deletes the GFCI requirements for swimming pools, fountains and similar installations. Most pool motor manufactures currently require GFCI protection as outlined in their installation instructions or product labeling.

Plumbing/Fuel Gas The elevation above which plumbing systems,

equipment and fixtures are required in flood hazard zones is clarified in Section 1612.4.

Code address the decomposition of grease

interceptors and automatic grease removal devices. The construction shall be able to withstand water-hydrogen ion (ph value) of 1.5 to 14 on all interior and exterior surfaces with no exceptions.

Fire Protection Code removes the Florida specific requirement

of 4-hour Fire Wall separation and retains the base code language for fire walls.

Party Walls no longer have the classification as a 4-hour fire resistance rating.

Fire Walls can be of any approved non-combustible materials with the exception of Type V construction.

Fire Protection The Florida specific language “for integrity in

accordance with NFPA 72, National Fire Alarm Code” has been deleted and replaced with

“monitored by an approved supervising station”. The Florida Specific language is deleted “in

accordance with NFPA 72” in favor of the 2010 IBC language “by a listed fire alarm control unit” for Sprinkler system monitoring and alarms.

Fire Protection Group B, Business occupancies. The term

“manual” is reinserted in the FBC. The added Exception indicates that manual fire alarm boxes are not required in a fully sprinkler building. This addition in the exception matches the IBC 2009 language.

The IBC “special inspection and testing requirements” is reinserted for Smoke Control Systems for buildings and structures.

Fire Protection

The Means of Escape, definition for Chapter 10 is clarified. The code deletes from the definition “that is independent of and remotely located from the means of egress”. The rational is that FBC and FFPC view this differently. The intent is to allow for protection of all exterior openings while providing a single means of escape form the building. The means of escape, while not meeting the definition of means of egress, is the way out and cannot be independent or remote from itself.

Fire Protection Floor surfaces as “walking surfaces along the means of

egress shall have a non-slip-resistant surface and be securely attached”.

The Florida Specific amendments for horizontal projections, is deleted and replaced with the base IBC code that address horizontal projections, clear widths, floor surfaces, and elevation changes.

Elevation change is clarified as “where changes in elevation of less than 12 inches in the means of egress, sloped surfaces shall be used. Where the slope is greater than 1:20 or 5%, ramps complying with code shall be used. Where difference in elevation is 6 inches or less, ramp shall be contrasted with adjacent floor finish materials”.

Fire Protection The minimum dimensions for means of egress ramps

deletes the “Exception: Ramps that are part of a required means of egress shall not be less than 44 inches wide”. The width of a ramp being used as a means of egress shall be 36”.

Table 1017.1- Corridor Fire-resistance Rating (FBC) for

occupancy “A”, changes to be consistent with Florida Fire Prevention Code, with sprinkler system from one hour rated to non-rated (0) to match IBC.

IBC, Chapter 9,Section 903.2.3 Group E (Educational)

an automatic sprinkler system shall be provided through-out all fire areas greater than 12,000 square feet in area. (This is a reduction from the 20,000 square feet.)

Fire Protection Roof access language is added, with the

exception from the IBC to the FBC. The protection at roof hatch openings is also added to Accessible stairs.

Exit Signs, FBC, Section 1011, is added

language from the IBC to the FBC.

Code modifies the Handrail continuity requirements by deleting the three sub-exceptions to exception 3 and adding a forth exception regarding handrails along walking surfaces.

Fire Protection The definition of fire barrier has been revised to limit its

application only to vertical assemblies, such as walls. Horizontal assembly has been added as a new definition that applies to fire–resistance rated floor or roof assemblies. These revisions and additions are to provide a better definition between vertical and horizontal assemblies.

Smoke control systems continued time of operation has

been increased by 1.5 times the calculated egress time after detection of the fire event plus the 20 minute limit.

Roofing/Building Base and counter flashing identifies the specific size of

the “L” flashing, a continuous metal 4” X 5”, ‘L’ flashing. Open valleys lined with a corrosion-resistant metal shall

be 16” wide not 24”.

A specific reference relevant to coatings such as elastomeric or maintenance coatings shall not be applied to existing asphalt shingles, unless approved by the shingle manufacturer.

Any corrosion identified and exposed on the roof side

shall be treated with a rust inhibitor, and check field fastener withdrawal resistance. PS: treat the underside of deck also.

Roofing/Building New code sections that will address the new photovoltaic

products as follows:

Section 1505.8 Photovoltaic modules/shingles, installed as roof coverings shall be labeled to identify the fire classification in accordance with the testing required in Section 1505.1

Section 1507.17 Photovoltaic modules/shingles adds

material standards, wind testing, and installation requirements for these products.

Chapter 35 is a new standard, UL 1703, Flat-plate Photovoltaic Modules and Panels for photovoltaic roofing material products.

Roofing / Building Code clarifies that the Granule Adhesion test is required

for mineral surfaced underlayment's that are used both mortar and adhesive set tile systems.

Code allows for additional installation options of concrete

and clay tile. No liquid applied roof coating systems are allowed on

asphalt shingle roofs. Code adds standard for photovoltaic flat-plate roofing

modules and panels.
