Chapter 1: Administration

Key items

Townhouse requirements(101.2) clarified...hopefully!

3-stories or less in one and two family code, appendix Z deleted.

Independent Structural Review (105.9) narrowed... Required on only high rise and complex structures Construction control(107.6) language tightened... Alternative means and methods which deviate from prescriptive code requirements must be submitted to the building official for approval, separate from the plans. IBC inspection language loosened (110.3) ... Construction inspection intervals may (not shall) include those set forth in sections 110.3.1 through 110.3.10 Periodic Inspection Table (Table 110) revised: Annual inspections of group residences removed. Fire escapes included in table. Temporary Certificate of Occupancy (111.3) : IBC language adopted authorizing building official.

Chapter 1: Administration

Referenced Codes (101.4)

·Specialized codes (M.G.L. c. 143, § 96): used in MA instead of or in conjunction with I-codes (IFC, IMC, IPC etc.). · Inspection of work under Specialized Codes by "individuals authorized by specialized codes". ·Specialized code work impacting building features subject to inspection by the building official. ·Access enforced by the building official. See M.G.L. c. 22, § 13A. ·Bunkers and magazines for explosive materials, flammable/combustible liquids and chemical process safety, defaults to 527 CMR and are enforceable by the head of the fire department rather than the building official. ·Sheet Metal Regulations enforced by the building official. See M.G.L. c. 13, § 102.

Specialized Codes

(MGL 143 § 96)

Plumbing 248 CMR Electrical 527CMR12 Access 521 CMR Fire Safety Code ? Fire Prevention 527 CMR Elevator 524 CMR Sheet Metal 271 CMR

·Fire Prevention (101.4.5): Reference to the IFC or IMC for fire prevention issues shall be considered reference to 527 CMR. If 527 CMR does not address, then IFC or IMC shall apply. If a conflict regarding fire prevention requirements exists between 527 CMR and 780 CMR the more stringent standard shall apply. ·Building code requirements in the IFC and IMC are made a part of 780 CMR and are enforceable by the building official. ·Oil fired appliances governed by 527 CMR 4.00.

Chapter 1: Administration

Other items of note: DDS Facilities (102.2.1): Additional safety features in one and two family dwellings for group residence do not change the building classification from one and two family. Work exempt from permit (105.2): Now specifies painting...cabinetry...finish work and playground equipment. Permit application (105.3): Indicate if licensed by a State care agency. Electronic seal (107.1.1): Allowed, see DPL website: Inspection intervals (110.3) : The building official shall conduct inspections...which may include inspections set forth in Sections 110.3.1 through 110.3.10. Lowest floor in flood zones (110.3): Certification must be submitted to BO that elevation is in compliance with section 1612.5 before work above that elevation proceeds Temporary Occupancy (111.3): Key change is that this IBC section is not amended. Like the 7th edition the building official has the sole authority to issue a temporary certificate. The 8th does not require consultation with the fire official (7th edition language). Unsafe structures (116.1) : Resurrected 6th edition language per DFS request.

Chapter 3: Use and Occupancy

Chapter 4: Special Use and Occupancy

Changes and noted issues:

References to IFC; 527 CMR takes precedence over IFC where 527 CMR specifically addresses the topic. Both 527 CMR & IFC needed to properly review/enforce (see 101.4.5). Fire department review; fire department must review/approve permit submittals (see 107.1.2). Mall Buildings (402); now also applies to Open Mall Buildings (402.2).

Open perimeter (402.6.1); Option to reduce from 60-foot minimum in certain cases. Garages (402.7.1);Passenger car garages and open garages can be under the mall with 2-hr horizontal assemblies and be considered separate building

High Rise (403); still Massachusetts specific: 70 feet vs 75 feet

Less than 420 feet (403.2.1); have less stringent fire-resistance requirements. Greater than 420 feet:

Spray-on coverings; more stringent impact resistance ratings for fire resistant spray-on coverings. 2 sprinkler risers (403.3.1); minimum of 2 fire sprinkler risers located remote from each other. Adjacent floors cannot be supplied by the same sprinkler riser.

Redundant water supplies (403.3.2); required for fire pump installations. 2-way radios (403.4.4) ; must have equipment so that fire department radios are functional. Venting smoke (403.4.6); must have means of venting smoke from building after fire. Stairs remoteness (403.5.1); increased for exit stairs, scissor stairs considered one exit. Additional stairway (403.5.2); required for buildings greater than420 feet. Luminous markings (403.5.5); required in the exit enclosures to highlight egress paths. Elevators; IBC provisions for fire service elevators and occupant evacuation elevators just now adopted.

Chapter 4: Special Use and Occupancy

Parking garages (406)

Vehicle barrier height (406.2.4); requirement increased to 2-feet 9-inches from 2-feet due to increase in average vehicle size. Open wall space (406.3.3.1)to qualify as open parking garage - amended to 25% from 20% to be consistent with MGL's.

Hazardous materials (414 & 415); Detailed changes, including new control area approach, that are too detailed for this presentation

Chapter 5 General Building Heights and Areas

Chapter 5

is independent of other chapters controls the size of a building of a particular `use' and `construction type'

Special Industrial buildings (503.1.1) are exempt from Chapter 5 requirements. Hospital construction (503.1.3.1)­ MGL c.111, § 51 requires hospitals to be of at least TYPE IB construction (see Chapter 6). Exception (504.1) ­ 527 CMR 10 gives authority to Fire Services relative to required fire lane size and layout.

Chapter 5 General Building Heights and Areas

Automatic Sprinkler system increase (504.2) / Big Residential buildings in MA get increases using full NFPA 13 systems ­ i.e. per 903.3.1.1. Unlimited areas buildings (507.4) of more than 1 story- this section is `reserved'. Mixed Use & Occupancy (508) is new to this chapter & addresses requirements for each USE/Separation/Accessory & Incidental Use requirements.

Chapter 9: Basics

·Few Technical changes...If you know the 7th then

you'll have a good start on the 8th.

· IBC makes Numerous references to the

International Fire Code 2009 (IFC).

·MA State Fire Code (527 CMR) takes precedence

over IFC where 527 CMR specifically addresses the topi c.

·Both 527 CMR & IFC needed to properly

review/enforce (901.1 Note 2)

·Impact of MGL c.148 § 26G

Chapter 9: Basics (cont.)

· Authority language streamlined: In most cases approval

authority lies with either the building official or fire official.

· Emergency responder radio coverage required for all new


· Required smoke alarms still photoelectric only. · Portable Fire Extinguisher section expanded. · Carbon Monoxide protection required for all

places with sleeping arrangements, not just where there is parking or fossil fuel burning equipment.

· Smoke Proof Enclosures: Unique MA requirement not

carried to the 8th edition.

Chapter 9: Basics (cont.)

· Several MA amendments to NFPA Standards are incorporated: ·NFPA 72, Fire Alarm Code: 2010 (not 2007) ·NFPA 720, Carbon Monoxide: 2009 (not found in IBC) ·NFPA 92B, Smoke Management Systems: 2009 (not 2005) ·NFPA 130, ...Transit and Passenger Rail Systems: 2010 (not

found in IBC)

· also NFPA 140, 15, and 750.

Changes and noted issues: Submittals (107.1.2): Local Fire Department must review/approve fire protection submittals for building permit. Authority (901.1): Contains multiple changes to enforcement authority, including issuance of a temporary C of O (909.19). Acceptance Tests (901.5).Building official and/or fire official (or third party) must witness acceptance tests Sprinkler requirements (Table 903.2) ·Most sprinkler thresholds in Tabular form. Note: fire area concept from IBC of where sprinklers are required is not valid. Sprinklers generally required throughout building when required. ·Non-nightclub A-2: sprinklered at 100 occupants; other A-2 triggers remain unchanged. ·Ambulatory Health Care: certain facilities sprinklered ·Mercantile Use with upholstered furniture: sprinklered Sprinkler Standards · Clarified NFPA 13R use ­ cannot be used in a Mixed Use building · Clarified that townhouses require fire sprinkler protection ·13R not allowed in R-Use when area greater than 12,000 ft. · Balconies of Type V construction need sprinkler protection when using a 13R system (903. A-2 Nightclub fire alarm activation(907.2.1.2) : illuminate egress; bring house lights to full; stop audible/visible distractions Use Group E fire alarm system(907.2.3): requires voice capabilities Smoke alarms(907.2.11): must be photoelectric type Sleeping areas in non-R Use (907.2.24): must have fire detection/notification system protecting the sleeping area and its egress­ for example a bunk room in a B-Use fire station. Manual Pull Stations (various sections): IBC allows these to be eliminated in certain sprinklered buildings...the 8th edition (like the 7th edition) for the most part requires manual pull stations. Independent third party review (909.2): required for performance-based smoke control systems

Chapter 9: Fire Protection Systems

Chapter 10: Means of Egress

MA-unique requirements of 7th & 8th Edition:

Fire escapes: Maintenance and certification, etc. MA-Specialized Codes: Express recognition of. B-use locking arrangements: Special MA-allowed locking arrangements for B-USE buildings where 1 tenant occupies an entire floor. Electromagnetic striker lock: Recognition of MGL c.143 § 3R. Nightclub egress: Special egress requirements for new construction nightclubs.

Chapter 10: Means of Egress

Differences between the 7th and 8th:

Minimum egress dimensions (1005.1): New construction minimum required egress dimensions for other than H & I-2 occupancies allowed when such occupancies equipped w/fire sprinklers and voice evacuation. Electrical rooms (1011.1.1) : Now required to have additional exit signage no more than 18 inches off of the floor. Exit travel distance increase for F-1 or S-1 Uses (1016.1) : Allowed exit travel distance increased to 400' for one story F-1 and S-1 Uses when such buildings equipped throughout w/fire sprinklers and buildings have automatic heat and smoke roof vents. Assembly main exit, (1028.2 EXCEPTION): For nightclubs w/50 or more occupants, this Exception allowing distributed exits is overridden by the primary main exit requirements for nightclubs .

Chapter 13: Energy Efficiency

Overview ·What is the Same?

·Technical and administrative MA Amendments. ·ASHRAE 90.1-2007 remains the default design option.


is different?

·Format and Section numbering ·No new major requirements; The devil is in the details...

Chapter 13: Energy Efficiency

Changes and noted issues:

MA Amendments; No technical/administrative differences between 7th & 8th Edition. Technical differences ; are between IECC-2006 w/2007 Supplement and IECC-2009. Format/Section numbering changes; exist between IECC-2009 and earlier variant. ASHRAE 90.1-2007(C1); remains the default design option. Administrative criteria (C1); C1 of the 8th overrides the admin. criteria of C1 of IECC2009. Vapor retarder (C4); requirements of IECC-2007moved to IRC-2009, C6 & C11. Prescriptive changes (T402.1.1 and T402.1.3); several numerical changes to R or U Factors. Optional air leak testing (402.4.1); allows, as an option, physical air leakage testing (testing is not mandatory as visual inspections allowed). Computer modeling (405); : "SIMULATED PERFORMANCE ALTERNATIVES" has an expanded set of guidance/requirements on how to do such computer modeling. Prescriptive changes (T502.1.2 & T502.2(1)); reflect more stringent R and U values and generally require different R and U values for "Commercial" buildings v. "Residential" buildings. Vapor retarder(C5); requirements of IECC-2006/2007 moved to C14 of the IBC-2009.

Chapter 13: Energy Efficiency

HVAC equipment performance requirements ( 503.2.3); the EXCEPTION, now in more detail, addresses water-cooled centrifugal water chilling packages not designed for operation at ARHI Standard conditions. Chiller efficiency (T503.2.3(7)); updated efficiency requirements. Snow melt systems (503.2.4.5); requires auto shutoff controls for heated pavements. Pipe insulation (T503.2.8); has slightly more conservative pipe insulation thicknesses than earlier table versions. Air systems (503.2.10): inclusive, addresses air system design and control. Hydronic pump system (503.4.3.3); "Hydronic (water loop) heat pump systems", inclusive, updated. Lighting in dwelling units (505.1) ; EXCEPTION, exempts lighting w/in dwelling units where 50% or more of permanently installed interior light fixtures use high-efficacy lamps. Total connected interior lighting power (505.5.1); EXCEPTIONS have been expanded. Exterior light zones (T505.6.2(1)); Table has been added. Total building performance (506 inclusive); has an expanded set of guidance/requirements on how to do such computer modeling.

Chapter 16: Structural Design

What is the same in the 7th and 8th?

Unique Snow and Wind loads Seismic coefficients same as IBC but values in Table Unreinforced Masonry (URM) not allowed Snow Drift Geometries go beyond ASCE-7 Some analysis methods not permitted

SAC* feels these will disappear from the national code soon. *Structural Advisory Committee

ASCE-7 2005 edition still in play

Town Houses (3 or less stories) Structural will be in the 8th 1&2.

Chapter 17 Structural Tests and Special Inspections


7th Edition `Unique' Chapter 17 Key Points:

­ Required a `Quality Assurance Plan' that was the ­ Responsibility of the `Registered Design Professional'


8th Edition MA amendments to IBC:

­ The owner shall provide for a registered design professional in responsible charge of controlled construction who shall:

· Assume BO duties assigned by the IBC · Submit a Test and Inspection Plan · Submit a Final Test and Inspection Report, prior to C of O.

Chapter 18 Soils and Foundations

This chapter is heavy with MA amendments

Essentially functions like 7th Broad coverage of various soil types and conditions

MA amendment allows Building Official to waive geotech investigation:

Where satisfactory data from adjacent areas is available that demonstrates an investigation is not necessary to meet the requirements of this chapter or, For unoccupied structures that do not pose a significant risk to public safety in the event of failure; or For structures used for agricultural purposes.
