Disclaimer This presentation attempts to familiarize users with the new 8th edition and specifically with what’s changed from the 7th edition. The information provided may have inaccuracies and cannot encompass all of the changes between the two editions of the building code. This training presentation may be found at the DPS website.

The 7th Edition Base Code
+ Embedded MA amendments = (Sold at State bookstore) Note: The code also references other MA codes (plumbing, electrical, etc.) and I-codes* which cover mechanical and energy requirements. *Can be purchased at

The 8th Edition uses I-codes
MA Amendments + Note: The code also references other MA codes (plumbing, electrical, etc.)

MSBC Front-end Amendments

Using the 8th Edition Base Code
Example: How do I find energy requirements for building envelope sealing? Go to chapter13 of IBC: IBC says to use IECC. Found in section of IECC. Check MA amendments for chapter 13: it also says use IECC but with MA amendments. Note: MA amendments in 13 are listed according to IECC section numbers and yes, section has been amended!

Chapter 1 Administration
Organization How did we get 25-sections of the 7th chapter 1 to fit into the 16-sections of the IBC chapter 1 and keep amendments to a minimum? Reviewed every section of the 7th; found its’ corresponding location in 8th or added amendments if needed. Deleted several topics not in use (Construction Materials Safety Board, for example) and moved embedded ‘convenience’ information to website. Deleted MGL language; provided web link to MGL’s instead. Deleted Special Regulations language (CSL, Native Lumber, etc.); referenced chapter 110 instead.

Chapter 1: Administration
IBC sections flow with project: General Applicability Dept. of Building Safety (Building Official) Duties of Building Official Permits Construction Documents Submittal Documents Temporary Structures and Uses Fees Inspections Certificate of Occupancy Service Utilities -reserved Board of Appeals Violations Stop work order Unsafe Structures and Equipment scope administration permitting construction problems

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 through Periodic Inspection Table 110 (was Table 106) revised: Annual inspections of group residences removed. Fire escapes included. 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 CMR Electrical CMR12 Access CMR Fire Safety Code ? Fire Prevention CMR Elevator CMR Sheet Metal CMR Fire Prevention ( ): 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.

Other items of note: DDS Facilities ( ): 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 ( ): Allowed, see DPL website: Inspection intervals (110.3) : The building official shall conduct inspections…which may include inspections set forth in Sections through Lowest floor in flood zones (110.3): Certification must be submitted to BO that elevation is in compliance with section 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 2: Definitions IBC definitions, some of which don’t exist in the 7th, were reviewed and retained. MA unique definitions added: Agriculture: as per MGL Agricultural , Building: Building Official: as per MGL Design Flood: as per DEP/Appendix G Design Flood Elevation: High-Rise Building: 70 for MA vs 75 feet in IBC. Jurisdiction: BBRS Night Club: Ordinance: means same as bylaw Registered Design Professional, RDP: applies to MA PE’s and registered architects. Specialized Codes: Just those listed in MGL 143 § 96 Story Above Grade Plane: Temporary Emergency Uses: Temporary Overnight Shelter:

Chapter 3: Use and Occupancy
Overview: In general, group homes, day care and related care facilities formerly in chapter 4 have been integrated into chapter 3. Once classified, all requirements to be enforced by the BO are found in the main body of the code. Special requirements and emergency evacuation requirements are covered by MA care agency regulations and enforced by the respective agency. 7th Chapter 4 Group Residences Day Care centers Limited Group Residence Detox. Facilities Group Dwelling units 8th Chapter 3 Moved to

Chapter 3: Use and Occupancy
Changes and noted issues: Day care: (305.2): MA cut-off age 2 yrs 9 mo vs IBC 2 yrs 6 mo. Group homes (308.2): No longer in chapter 4. Caveats retained to ensure one and two family group homes with five or fewer residents are treated strictly as one and two family dwellings. Ability to evacuate during emergencies is care agency’s responsibility - BO only inspects for compliance with the building code. I-2 and Residential care/assisted living facilities: (308.3) I-2 type facilities with up to 12 residents licensed or operated by DMH may be considered R-4 facilities. Child care vs Day Care ( ): To be determined if the term ‘child care’ is in error in this section and 310 of the IBC as these sections discuss care for less than 24 hours which is considered ‘Day Care’ elsewhere. R-1 classification (310.1): Summer camps listed but requirements still in chapter 4. R-2 classification (310.1): Includes day care of up to 10-children in an apartment and DMH licensed or operated units. R-3 classification (310.1): Day care of up to 10 children allowed in a unit. Townhouses of more than 3-stories added to list with note that height and area and fire protection in accordance with R-2. DDS and DMH group type facilities also noted. Definitions (310.2): Boarding House references the MGL definition; Congregate Care Facilities – definition added; Residential Care/Assisted Living Facilities – Elder Affairs and DMH MGL’s cited. Summer Camps- definition added.

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 ). Fire department review; fire department must review/approve permit submittals (see ). Mall Buildings (402); now also applies to Open Mall Buildings (402.2). Open perimeter ( ); Option to reduce from 60-foot minimum in certain cases. Garages ( );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 ( ); 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 ( ); minimum of 2 fire sprinkler risers located remote from each other. Adjacent floors cannot be supplied by the same sprinkler riser. Redundant water supplies ( ); required for fire pump installations. 2-way radios ( ) ; must have equipment so that fire department radios are functional. Venting smoke ( ); must have means of venting smoke from building after fire. Stairs remoteness ( ); increased for exit stairs, scissor stairs considered one exit. Additional stairway ( ); required for buildings greater than420 feet. Luminous markings ( ); required in the exit enclosures to highlight egress paths. Fire Service Elevators ( ); required in all high-rise buildings Occupant Evacuation Elevators ( ); IBC provisions for occupant evacuation elevators were not adopted by 780 CMR

Parking garages (406) Vehicle barrier height ( ); requirement increased to 2-feet 9-inches from 2-feet due to increase in average vehicle size. Open wall space ( )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
Independent of other chapters Controls the size of a building of a particular ‘use’ and ‘construction type’ Special Industrial buildings ( ) are exempt from Chapter 5 requirements. Hospital construction ( )– MGL c.111, § 51 requires hospitals to be of at least TYPE IB construction (see Chapter 6). Exception (504.1) – 527 CMR 10 & 25 give authority to Fire Services relative to required fire lane size and layout.

General Building Heights & Areas Chapter 5
The allowable building height in stories has been reduced for Use Groups B, M, S-1, and S-2 of Construction Types IIB and IIIB. See Table 503 for all height and area requirements. Use Group 7th Edition 8th Edition Business (B) 4 Stories 3 Stories Mercantile (M) 2 Stories Moderate Hazard Storage (S-1) Low Hazard Storage (S-2)

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 Unlimited areas buildings (507.4) of more than 1 story- this section is ‘reserved’. Mixed Use & Occupancy (508) has been relocated to this chapter with some changes and addresses requirements for each USE/Separation/Accessory & Incidental Use requirements.

Accessory Areas Section 508.2
Fire separation assembly not required Not more than 10% of any fire area Does not exceed tabular values in Table 503 Construction type and fire protection system requirements based on main use of building Areas that require a fire barrier High Hazard (Use Group H) Incidental Use Areas (Table ) Assembly areas that are not considered separate occupancies/ exceptions to general accessory area rules Rooms less than 750 SF (Section Ex.3) Accessory to Group E (Section Ex. 4)

Accessory Areas Section 508.2
Example: Office building Type IIA Construction Unsprinklered No Perimeter Access Business Use (B) 30,000 SF Total Fire Area = 37,500 SF Actual Floor Area (Main Use + Accessory) Allowable Area of Building (B) = 37,500 SF Allowable Area of Accessory Use (S-1) = 26,000 SF Storage Area is < 26,000 SF OK 10% of Total Fire Area = 3,750 SF Storage Area is > 3,750 SF NOT OK Accessory Area Does NOT Comply Storage Use (S-1) 7,500 SF

Incidental Accessory Occupancies Section 508.2
Require separation/ protection per Table Rated construction Automatic fire-extinguishing system Only incidental accessory space must be protected Smoke resistant walls Automatic or self-closing doors Incidental storage rooms over 100 ft2 are no longer required to be separated by 1 hour.

Incidental Accessory Occupancies Section 508.2.5
Table is no longer divided by use group. Removed storage rooms > 100 sf Fire pump rooms must be 2-hr rated 1-hr and sprinkler protection permitted in non-high rise buildings

Non-separated Use Groups Section 508.3
No fire separation required between uses, unless required by other provisions Height and area limited by most restrictive use Fire protection systems provided throughout in accordance with most restrictive use All other requirements apply to each portion of the building based on use group

Separated Use Groups Section 508.4
Fire separation assembly required between uses when required by Table 508.4 Height and area limited based on a pro-rated calculation All other requirements apply to each portion of the building based on use group Sprinkler protection required based on most restrictive use of a fire area as required by Chapter 9

Height and area limitations for each fire area are based on use group In each story, the sum of the ratios of the actual floor area to allowable area for each use group must not exceed one.

Separated Buildings Section 503.1.2
Separated by fire wall per Section 706.1 Code requirements based on use group(s) and construction type of each building individually Height and area limitations apply to each building individually

Special Provisions Section 509
Special conditions that are exempt from, or modify, the height and area requirements of Chapter 5 Horizontal building separation allowance Enclosed parking garage with open parking garage above Group R-1 & R-2 of Types IIA & IIIA Group B & M with open parking garages Multiple Buildings above parking garages

Markings and Identification Section 703.6
Fire walls, fire barriers, fire partitions, smoke barriers, and smoke partitions, or any other wall required to have protected openings or penetrations must be identified with signs or stenciling Required at 30’ intervals horizontally “FIRE AND / OR SMOKE BARRIER – PROTECT ALL OPENINGS”

Sprayed Fire-Resistance Materials Section 704.13
Specifically regulates the application of SFRMs to minimize the potential for the materials to be dislodged; including: Surface conditions Substrate conditions Conditions for applying to primers, paints and encapsulates Flange depth Web depth Temperature at time of installation Finished condition

Exterior Walls Sections 705.5 & 714.4.1
Exterior walls are required to be rated for fire exposure from both sides when the fire separation distance is 10’ or less (previously 5’ or less). Clarification: Voids between exterior curtain walls and nonfire-resistance-rated floor or floor/ceiling assemblies must be sealed with approved material to retard the interior spread of fire and hot gasses. Source: ICC 2009

Fire Protection Systems Chapter 9
Background: BBRS voted to carry forward 7th edition Chapter 9 requirements and not lower level of safety from that required by 7th edition IBC has ‘enforcement authority’ language that needed to be addressed.

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 topic. Both 527 CMR & IFC needed to properly review/enforce (901.1 Note 2)

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 buildings Required smoke alarms still photoelectric only. Portable Fire Extinguisher section expanded. Carbon Monoxide protection clarified…is 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.

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: (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 ( ): 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 ( ) A-2 Nightclub fire alarm activation( ) : illuminate egress; bring house lights to full; stop audible/visible distractions Use Group E fire alarm system( ): requires voice capabilities Smoke alarms( ): must be photoelectric type Sleeping areas in non-R Use ( ): 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

Fire Command Center Section 911.0
Min area of fire command center is 200 SF Min dimension in any direction is 10 ft. 1 hour rated room Location subject to the approval of the Fire Department

Smoke Control System Smoke control design based on an engineering analysis using NFPA 92B (909.8) Smoke layer height reduced to 6’ ( ) Computer Fire Modeling Code Exhaust Requirement (cfm) 6th Edition: Axisymmetric * 195,930 Code Exhaust Requirement (cfm) 2,000 Btu/s 5,000 Btu/s 8th Edition: Axisymmetric 207,830* 299,850** 8th Edition: 20' Wide Balcony Spill 479,655 664,430 8th Edition: Window Spill Plume 187,695 203,185 8th Edition

Means of Egress Chapter 10
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.

Means of Egress Chapter 10
Differences between the 7th and 8th: Minimum egress dimensions (1005.1): 7th Edition egress factors of 0.15 / 0.2 allowed (except in H & I-2 occupancies) only when equipped w/fire sprinklers AND voice evacuation. Otherwise must use 0.2 / 0.3 egress factors. Electrical rooms ( ) : 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, ( EXCEPTION): For nightclubs w/50 or more occupants, this Exception allowing distributed exits is overridden by the primary main exit requirements for nightclubs .

Minimum Guard Height at Fixed Seating Section 1013.2
Fixed seating next to a guard is now considered a walking surface, the minimum height of the guard is now measured from that surface. Source: ICC 2009

Single Means of Egress Section 1014.3 &1015.1
Use Group R-2 Occupant load increased from 10 to 20 people in buildings equipped with an automatic sprinkler system. Common path of travel increased from 75’ to 125’ in buildings equipped with an automatic sprinkler system. Day Care (E or I-4) Max. occupant load of 10 for single-exit classrooms (350 sq. 35 sq. ft. per occupant) 7th Edition limit was 50 people (1,000 sq. ft.)

Dead Ends Section 50 ft dead end allowance expanded to include fully sprinklered Use Groups E, I-1, M, R-1, R-2, R-4, S and U in addition to Use Groups B and F

Open Egress Stairs Section 1022.1 & 1016.1
Exceptions 3 & 4 allow 2 story open stairs to serve as required means of egress. Exceptions moved to exit access section (no exception in stair enclosure section) Travel distance measured along open stair to exterior door or rated exit enclosure.

Energy Efficiency Chapter 13
Overview What is the Same? Technical and administrative MA Amendments. ASHRAE remains the default design option. What is different? Format and Section numbering No new major requirements; The devil is in the details…

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 (C1); remains the default design option. Administrative criteria (C1); C1 of the 8th overrides the admin. criteria of C1 of IECC-2009. Vapor retarder (C4); requirements of IECC-2007moved to IRC-2009, C6 & C11. Prescriptive changes (T and T ); several numerical changes to R or U Factors. Optional air leak testing ( ); 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 (T & 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.

HVAC equipment performance requirements ( ); the EXCEPTION, now in more detail, addresses water-cooled centrifugal water chilling packages not designed for operation at ARHI Standard conditions. Chiller efficiency (T (7)); updated efficiency requirements. Snow melt systems ( ); requires auto shutoff controls for heated pavements. Pipe insulation (T ); has slightly more conservative pipe insulation thicknesses than earlier table versions. Air systems ( ): inclusive, addresses air system design and control. Hydronic pump system ( ); “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 building performance (506 inclusive); has an expanded set of guidance/requirements on how to do such computer modeling.

Energy Code Additions, renovations, and repairs to an existing building must conform to the code for new construction, without requiring the unaltered portion of the building to comply If the energy use of the building is not increased the following need not comply: Storm windows Glass only replacements in existing sash and frame (unless required elsewhere in IEBC) Existing ceiling, wall, and floor cavities exposed during construction – if filled with insulation Construction where existing roof, wall or floor cavity is not exposed

CHAPTER 115 AA Stretch Energy Code
Overview The STRETCH ENERGY CODE is the first locally adoptable set of 780 CMR regulations that the BBRS has ever promulgated. This Energy Code affects low rise residential buildings (both new construction and existing buildings when undergoing renovation), as well as new construction “commercial” buildings of certain sizes (but does not impact existing “commercial” buildings undergoing renovation (baseline energy code requirements do impact existing “commercial” buildings undergoing renovation.

Structural Design Chapter 16
What is the same in the 7th and 8th? Unique Snow and Wind loads Seismic coefficients same as IBC but values in Table of ASCE 7 have been amended by MA. 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 edition still in play Town Houses (3 or less stories) Structural will be in the 8th 1&2.

IEBC Key ‘Structural’ Amendments
6th and 7th edition ‘Essential Elements’ brought forward Investigation and Evaluation ( ) Required for ‘Construction Control’ projects Table of ‘Basic Seismic Force Resisting Systems’( ) Reduced level of seismic forces permitted for certain projects ( ) Modified ‘reduced seismic level force’ requirement to be consistent with the 6th edition. (IEBC is a fixed 75%)

IEBC Key ‘Structural’ Amendments (cont.)
Added ‘cumulative effects of alterations since original construction’ (various locations) Inserted a list of triggers to allow minor alterations to proceed with no or minimal structural analysis. (101.9) Added a requirement for anchorage of unreinforced masonry (101.10)

Modified parapet bracing requirement to include Seismic zones B and C. ( ) Note that IEBC requires this work only when reroofing is done. Exception for low height to thickness ratios Relief provided on structural triggers on reroofing ( ) Raised trigger to >105 mph (was > 90 mph) Note this will include much of greater Boston Only in cases of complete reroofing (was >50%)

Relief provided on vertical additions. IEBC requires compliance to ‘full seismic’. ( ) Amendment allows for ‘reduced seismic’ However, no relief on horizontal additions Modified ‘Appendix A1’ to assign prescribed values of certain masonry properties without testing. ( appendix A1) IEBC wind loads requirements not changed.

Risk Abatement Analyzed typical existing building projects / these “sample projects” will be placed on the DPS web site during February 2011. Completed these (others pending): Solar Panel Installation (2 different projects) Mill Building B and S-Use Renovation Conversion of Warehouse of B-Use to Residential Elevator Installation Modernization of an Apartment Building Tenant Improvement Three Family Energy Upgrade Condo Complex Window Replacement Row Building In general, IEBC is consistent with past practice.

Three Compliance Methods
Work Area Method may have some dependency between chapters. The method is the choice of the owner. The three methods are independent.

Compliance Methods Three ways to comply with the code:
Prescriptive Compliance Method: Additions, alterations or repairs, unless otherwise noted, follow that of new construction. Mostly seismic upgrade requirements Intended for newer buildings Requires full compliance with IBC Structural requirements Work Area Compliance Method: Requirements are based on level of work and generally apply to work area only. Performance Compliance Method: Utilizes a point system to ensure the level of public safety, health & welfare is maintained or exceeded after a renovation. Permits flexibility with unique projects Regardless of which option is chosen, IEBC Chapter 1 always applies and contains many unique MA amendments (i.e. structural systems, egress, fire protection, etc).

Existing Building Reports IEBC MA Amendment Section 101.5.4.0
For any proposed work regulated by this code, the existing building shall be evaluated in accordance with the provisions of this code, including: Design gravity loads Lateral load capacity Egress Capacity Fire protection systems Fire resistive construction Interior environment Hazardous materials Energy conservation A written report must be submitted to the building official as a condition of the issuance of a building permit.

Prescriptive Compliance Method Chapter 3
IEBC Prescriptive Compliance Method Chapter 3

IEBC: Prescriptive Classifications
In general all new work or new components of altered systems must comply with the code for new construction. Specific Chapters containing requirements for: Additions Alterations Repairs Fire escapes Change of Occupancy Historic Buildings Moved Structures

Prescriptive Compliance Method Section 303.3 – 303.4
Alterations: Existing structures carrying gravity loads must meet the code for new construction under any of the following circumstances: The design gravity load is increased by 5%. The capacity of the structural member is reduced. Existing structures carrying lateral loads must meet the code for new construction under any of the following circumstances: The design lateral load is increased. The alteration results in a structural irregularity as defined in ASCE 7. Exception: Lateral load-carrying members where the demand-capacity ratio with the alteration is increased by less than 10% of the ratio when ignoring the alteration.

Work Area Method Chapters 4 – 12
IEBC Work Area Method Chapters 4 – 12

Work Area Compliance Chapters 4 - 12
Provisions are based on the type of work as defined in Chapter 4 Repairs (402): Patching, restoration, or replacement of damaged elements to good or sound condition for maintenance purposes. Level 1 Alteration (403): Alterations to elements to serve the same purpose. No reconfiguration of spaces. Level 2 Alteration (404): Reconfiguration of spaces Addition or elimination of windows or doors Installation of any additional equipment Renovation area ≤ 50% of the aggregate building area. Level 3 Alteration (405): Renovation area > 50% of the aggregate building area. Change of Occupancy (406) Additions (407) Historic Buildings (408) Relocated Structures (409)

Work Area Defined as: The portion or portions of a building consisting of all reconfigured spaces as indicated on the construction documents. Excludes other portions of the building where incidental work entailed by the intended work must be performed and portions of the building where work not initially intended by the owner is specifically required by this code.

Repairs Chapter 5 Non-structural repair work other than routine maintenance / and where such repairs require a permit / can be made with same or like materials. Unique to Massachusetts: Means of Egress Repairs Egress capacity Exit signage and lighting Unsafe or dangerous conditions Structural Repairs Extent of damage determines the loads to be used for design of repaired building In some cases, repairs can meet The code for construction that was in effect at the time the building was constructed The reduced loads table, Table (unique to MA) The code for new construction Delete Electric and Plumbing Requirements

Level 1 Alteration Chapter 6
New finishes must comply with 780 CMR for new construction (602.1 – 602.3). New work must comply with the materials and methods of the applicable code (602.4). Major alterations could require sprinklers Structural upgrades could include: Gravity members if dead load increased by > 5% Anchoring / bracing of masonry / concrete walls Roof diaphragms and connections to resist wind loads

Compliance with Level 1 work required (701.2). All new construction and elements must comply with the code for new construction except as noted in Chapter 7 (701.3). For example dead end corridors and ceiling heights have slightly less stringent requirements. All floor openings must be enclosed with 1-hour fire resistance rated construction except: Where permitted by the code for new construction The entire area is open and unobstructed (with limitations) Use Group specific allowances for rating reductions or allowed floor openings Existing vertical openings up to 3 stories are permitted in fully sprinklered buildings of Use Group B, E, F, M, R-1, R-2, S

Level 2 Alteration Floor Openings (703.2)
Additional Requirements ( ): If work area exceeds 50% of the floor area, then all vertical openings other than stairways must comply with (applies outside work area) Does not include vertical openings in tenant spaces completely outside the scope of work. Stairway Enclosure Requirements ( ): If work area exceeds 50% of the floor area, then all egress stairways must be enclosed with smoke-tight construction (at a minimum) from the highest work area floor and all floors below. Unless enclosure is not required by 780 CMR

Existing interior finishes in exits and corridors within work area must comply with 780 CMR requirements (703.4) If the work area is > 50% of the floor area, entire floor must use 780 CMR approved finishes Automatic sprinkler systems must be installed in the work area if: (704.2) The work area has exits or corridors shared by more than one tenant or they serve more than 30 occupants The work area exceeds 50% of the floor area The water supply is sufficient 780 CMR requires it Fire alarm systems are required in the work area for Use Group E, I, and R occupancies (704.4) Required throughout the floor if the work area exceeds 50% of that floor In general, egress requirements for doorways or corridors in work areas follow that of new construction ( ) Egress lighting and exit signs are required in work areas ( )

Structural: New structural members, meet code for new construction Alterations not resulting in supporting additional loads can use the loads applicable at the time the building was constructed as the minimum design loads Gravity load requirements Exception: Since original construction, structural elements whose stress is not increased by more than 5 percent Lateral load requirements apply when the alteration is considered more than 10 percent greater than its demand-capacity ratio with the alteration ignored Voluntary lateral-force-resisting alterations Not required to comply with forces in IBC provided that an engineering analysis complies with 4 conditions

Compliance with Level 1 and 2 work required (801.2) Existing shafts and vertical openings must be protected in accordance with from the floor of the work area to the level of exit discharge (803.1) Fire alarm and detection systems must be provided throughout the building where required by Section (Level 2). Means of egress lighting must be provided within exits from the highest work area floor to the floor of exit discharge (805.2). Exit signs must be provided from the highest work area floor to the floor of exit discharge (805.3).

Structural: New structural elements meet Level 2 requirements Existing structural elements carrying gravity loads meet Level 2 requirements Structural alterations Except Group R with no more than 5 units altered using light-frame construction methods of the IBC Except when alterations are only to the lowest story and there’s no change of occupancy, only lateral-force-resisting components in and below that story need comply with the Level 3 requirements Engineering evaluation required Within a 12 month period, where more than 30 percent of the total floor and roof areas have been or are proposed, the engineering evaluation must determine if the building complies with the IBC for wind loading and the IBC level seismic forces Within a 12 month period, where not more than 30 percent of the total floor and roof areas have been or are proposed, the engineering evaluation must determine if the building complies with the loads applicable at the time of the original construction

Change of Occupancy Chapter 9
IEBC Change of Occupancy Chapter 9

Definition - A change in the purpose or level of activity within a building that involves a change in application of the requirements of this code Applies When the building has a change in occupancy, even if the occupancy classification is not changed Where there is a change in the occupancy classification or the occupancy group designation changes

Where the change in use is to a special use category, the building must comply with the code for new construction (902.1) Covered mall buildings Atriums Motor vehicle-related occupancies Aircraft-related occupancies Motion picture-projection rooms Stages and platforms Special amusement buildings Incidental use areas Hazardous materials Light and ventilation requirements must comply with the requirements of 780 CMR for the new occupancy.

Partial Change in Use Where not separated from the remainder of the building, the entire building must comply with Level 3 requirements Fire sprinkler, alarm & detection systems are required based on the new occupancy Interior finishes of areas that changed occupancies must meet the requirements of new construction (912.3) Hazard Categories determine what needs to be updated to new construction standards when changing occupancies.

Chapter 4: ‘the test’ Please put on your thinking caps…
For review of 14 proposed projects Make clarifying assumptions if you need to Confer with your neighbor if you so choose Assign, with your best educated guess, a ‘class’ to each project; Alt 1, Alt 2, Rep, C of O, etc. You have 5 minutes!! Please keep in mind; There are no ‘wrong’ answers

Chapter 4 Classification Examples
Project Description Ch 4 Class? 1) Removal of asphalt roof down to the sheathing & reroof w/asphalt 8) Installation of exterior millwork on an historic building. 2) Tenant fit-out of 6 stories of the Prudential Tower in Boston 9) Restoration, replacement, & patching of clapboard siding. 3) Addition of two stories to the top of a 10-story building 10) Removal of a oil furnace and replacement with gas furnace 4) Addition of solar panels to a 2-story steel frame building 11) Condo conversion. Includes new window for each garden unit. 5) 3 Unit R-2: Remove/replace plaster and lathe, electrical and insulation. Same number & location of doors and windows, but most replaced. 12) Strip mall. Building A/C unit replacement with new duct work to service new tenant on end unit. 6) Mill Building Conversion: F-Use to R-Use 13) 6 unit R-2: Blown in cellulose insulation 7) Removal of asphalt roof & reroof w/copper. 14) A structurally independent horizontal addition to the BPL

Hazard Categories Example Means of Egress (912.4)
When changing to a higher hazard category occupancy, means of egress must comply with new construction. When changing to equal or lesser occupancy hazard category: Existing egress elements must comply with Level 3 Alteration criteria New egress elements must meet criteria of new construction. Either way, the egress capacity must meet or exceed the requirements for new construction for the occupancy.

OCCUPANCY CLASSIFICATIONS OCCUPANCY CLASSIFICATION
Hazard Categories Example Heights and Areas and Exposure of Exterior Walls (912.5 & 912.6) Table 912.5: When changing to a higher Hazard Category heights and areas of buildings and structures shall comply with the requirements of Chapter 5 RELATIVE HAZARD OCCUPANCY CLASSIFICATIONS 1 (Highest Hazard) H 2 A-1, A-2, A-3, A-4, I, R-1, R-2, R-4 3 E, F-1, S-1, M 4 (Lowest Hazard) B, F-2, S-2, A-5, R-3, U Table 912.6: When changing to a higher Hazard Category exterior walls shall have fire resistance and exterior opening protectives as required by the International Building Code. RELATIVE HAZARD OCCUPANCY CLASSIFICATION 1 (Highest Hazard) H 2 F-1, M, S-1 3 A, B, E, I, R 4 (Lowest Hazard) F-2, S-2, U

Performance Compliance Methods Administration
IEBC Performance Compliance Methods Administration

Performance Compliance Methods Chapter 13
The design evaluation is comprised of three main categories: Fire Safety Structural Fire Resistance Automatic Fire Detection Fire Alarm Fire-Suppression System Means of Egress Configuration Characteristics Support Features General Safety Fire Safety Parameters Means of Egress Parameters

Example Evaluation Table Section 1301.6.17
Automatic Sprinklers Points are awarded based on the ability to suppress a fire based on the installation of automatic sprinklers per IBC Note: Sprinklers required by M.G.L. c. 148 §26G are not considered required for this section. Sprinklers are required throughout; however, not provided or not adequate for the hazard protected per IBC 903 Required in a portion of the building; however, not provided or not adequate for the hazard protected per IBC 903 Not required and none are provided Required in a portion of the building, provided in compliance with code at time of construction, and maintained/supervised per IBC 903 Required throughout and are provided per Chapter 9 of IBC Not required throughout but are provided per Chapter 9 of IBC

Evaluation – Safety Scores Section 1301.8

Evaluation – Building Safety Section 1301.9
If the building score is higher than the required score the building is compliant Mixed Occupancies: If not separated per the categories in , the mandatory safety scores for the occupancy with the lowest general safety score shall be utilized If separated per a category in then each occupancy should be scored separately based on the appropriate occupancy
