THE USERS' GUroE TO THE SIXTH EDITION 

PART I - OVERALL CHANGES 

The Sixth Edition of the Massachusetts State Building Code is based on the provisions of the 1993 BOCA 
National Building Code. However, since significant changes have been made to the national code, the Sixth 
Edition is considered a unique document to the Commonwealth. One should not assume that the two 
documents are compatible. There are several reasons for differences between the two codes, some of which 
are identified below. 

(1) In some instances, requirements of Massachusetts General Laws (M.G.L.) conflict with provisions 
of the national code. Since law is superior to regulation, the national code must be stripped of any 
confliaing language. 

(a) The Board of Building Regulations and Standards (BBRS) is fortunate to employ the services of 
various subcommittees comprised of learned and experienced professionals who donate their time in 
review of the code. Members of these subcommittees focus on certain aspects of the code and adapt 
its language to suit local peculiarities that may not be considered in the national code. These 
subcommittees include: 

1 . The Geotechnical Advisory Committee, 

2. The Fire Prevention, Fire Protection Advisory Committee, 

3. The Loads Advisory Committee, 

4. The Seismic Advisory Committee, and 

5. The Energy Advisory Committee. 

Also, Massachusetts must coordinate the provisions of the state building code with the provisions of 
other specialized codes under the control of separate indep>endent boards. Some of the specialized codes 
include: 

6. The Fire Prevention Code (527 CMR), 

7. The Elevator Code (524 CMR). 

8. The Architectural Access Regulations (521 CMR), 

9. The Plumbing and Gas Code (248 CMR), and. 

10. The Electrical Code (527 CMR). 

(b) The following chapters, are considered entirely unique to the Commonwealth differing significantly 
from the national code, and are so identified with a parenthetical statement below the chapter title. 
The chapters include: 

Chapter 1 - Administration 

Chapter 9 - Fire Protection Systems 

Chapter 1 1 - Accessibility 

Chapter 13 - Energy Conservation 

Chapter 16 - Structural Loads 

Chapter 18 - Foundations and Retaining Walls 

Chapter 27 - Electrical Wiring and Equipment 

Chapter 29 - Plumbing and Gas Fitting 

Chapter 30 • Elevator and Conveying Systems 

Chapter 34 - Repair, Alteration and Change of Use of Existing Buildings 

Chapter 35 • Manufactured Buildings, Building Components and Mobile Homes 

Chapter 36 - The One and Two Family Dwelling Code 

(c) Changes in other chapters are identified \vith bolded, italicized face type. 

(2) Part n of this Guide contains a summary of some of the major changes relative to the national code 
and to the Fifth Edition of the Massachusetts Building Code. 

(a) The first change a user will note in the Sixth Edition of the code is the numbering system. 
Recently, three national code agencies joined forces in the hopes of someday producing a uniform, 
international building code. The first matter that these agencies agreed upon in this pursuit was to use 
a chapter format in lieu of the article system. Massachusetts has followed this lead. 

(b) Recognizing the frustration that may develop in attempting to retrieve information utilizing this 
new system, a cross-index of article and primary section numbers of the Fifth Edition relative to the 
chapter and primary section numbers of the Sixth Edition is included as Part HI of this Guide (again, 
please note that Part Dl is nol meant as an absolute authoritative source identifying all changes from the 
Fifth Edition - refer to the actual code for definitive requirements).

PART II - SUMMARY OF CHANGES TO EACH CHAPTER 

CAUTION 

These suminaries are meant as a transition tool for users of the Sixth Edition of the Massachusetts State 
Building Code and only highlight certain major changes. The summaries are not designed as an 
authoritative source for all changes either from the National Building Code or the Fifth Edition of the 
Massachusetts State Building Code. Always refer to the actual code documents for definitive , 
requirements. 

Part n of this Guide contains brief summaries of the major changes from BOCA National Building Code, 
and from the Fifth Edition of the Massachusetts State Building Code. 

CHAPTER 1 - ADMINISTRATION 
(Fifth Edition Article 1) 
DifTerences from National Building Code: 

Chapter I is considered unique to Massachusetts. Essentially it is a combination of Fifth Edition 
requirements and the national document. 

Changes from the Fifth Edition of the Massachusetts State Building Code: 

Some of the major changes in Chapter 1 occur in Section 105, which defines the qualifications and 
certification requirements for all those who serve as building code enforcement officials in the 
Commonwealth; Section 1 10.0, which delineates procedures for the placement of manufactured buildings 
(requiring a licensed construction supervisor to secure a permit for the work and a certified set crew to 
install the structure); Section 116.0, which more clearly defines the role of registered architects and 
profesdonal engineers in the course of building construction; and Section 121.0 which defines the remedy 
available to person ordered to remove a dangerous structure (the route is through the courts, not through 
aboard of appeals). 

CHAPTER 2 - DEFINrnONS 

(Fifth EdMon Article 2) 
Differences from the National Code 

All definitions from the national code appear in this chapter. In a few instances, the wording was modified 
to reflect Massachusetts law or to clarify a definition. Also, some defimtions specific to Massachusetts 
were added, such as inspector of buildings and local inspeaor. 

Changes from the Fifth Edition of the Massachusetts State Building Code: 

Although many definitions are provided for in Chapter 2, the national code chooses to separate others and 
place them within the chapter in which they most closely relate. For instance, words and terms specific 
to means of egress requirements are found in Chapter 10, not Chapter 2. 

CHAPTER 3 - USE OR OCCUPANCY 

{Fifth Edidon Article 3) 
Differences from the National Code: 

Chapter 3 is compatible with the national code. However, portions of Section 3 13.0, Mixed Use Groups, 
are effected by changes that occur in Chapter 9 relative to fire suppression requirements of certain • 
buildings. 

Changes from the Fifth Edition of the Massachusetts State Building Code: 

A feature added to the national code is found Section 302, which defines requirements for certain specific 
occupancy areas within buildings. Also, Section 307.0 describes four subclassifications for the High 
Hazard Use Group Classification, whereas, the Fifth Edition defines only one.

USERS' GUIDE 

CHAPTER 4 - SPECIAL USE AND OCCUPANCY 

{Fifth Edition Article 6) 
DifTerenccs from the National Code: 

Chapter 4 is consistent with the National Code from Seaions 401.0 to 421.0 excepting changes 
incorporated due to conflicts with Massachusetts laws and\or regulations, such as those that occur in 
Section 603.0, defining the limits of high rise buildings, and Seaion 421.0, defining requirements for 
inground swimming pools. 

Sections 422.0 through 429.0 are unique to the Commonwealth, defining special uses that do not appear 
in the national code. Some of these sections have been brought forward from the Fifth Edition of the code 
with little change; they include provisions for existing structures in Section 422.0, summer camps for 
children in Section 425.0, and detoxification centers in Section 428.0. 

Sections 423.0, 427.0 and 429.0 which define special code provisions for group residences, limited group 
residences, and group dwelling units have been brought forward but have been modified to reflect new 
philosophies in the care of the occupants of these residences. These changes appear for the first time in 
the Sixth Edition of the code. The day care provisions in Seaion 424.0 have also been modified to increase 
occupant safety. 

Possibly the most significant change to Chapter 4 appears in Section 426.0. This section defines 
requirements for bulk storage merchandising buildings. Such buildings contain sales areas with high piled 
combustible commodities, and\or hazardous materials. Inherently, these structures present different fire 
and life safety risks than traditional retail structures. Section 426.0 provides adequate safety to the patrons 
of these facilities and reduces the possibility of excessive property loss due to fire. The seaion is newly 
developed for the Sixth Edition of the code. 

DifTerenccs from the Fifth Edition of the Massachusetts State Building Code: 

Chapter 4 is significantly different than the compatible Fifth Edition of the code. To start, special use 
provisions are no longer found in Article 6, also several new provisions have been added such as those 
defined above, and more detailed requirements for high hazard uses. 

CHAPTER 5 - GENERAL BUILDING UMTTATIONS 

{Fifth Edition Article 5) 
Differences from the National Code: 

Chapter 5 is almost entirely compatible with the national code, excepting the addition of note m to Table 
503 which cautions the code user to a distinaion of Massachusetts general law requiring hospitals, other 
than college or school infirmaries, to be erected of Type IB construction or better. 

Changes from the Fifth Edition of the Massachusetts State Building Code: 

Chapter 5 is very similar to the comparable Fifth Edition article. Methodoli^es relating to building size 
have remained constant for years, dating to work of insurance companies that originally developed the 
requirements. However, some requirements that appeared in the building limitations seaion of Article 5 
have been moved to a more appropriate place. Provisions for accessibility, for instance are found in 
Chapter 11. 

CHAPTER 6 - TYPES OF CONSTRUCnON 

{Fifth Edition Article 4) 

DifTerenccs from the National Code : 

Chapter 6 is entirely compatible with the national code. 

Changes from the Fifth Edition of the Massachusetts State Building Code: 

Types of construction are located in Article 4 in the Fifth Edition. Location is the major change in the new 
code, some language is condensed relating to the description for the five types of construaion.

THE MASSACHUSETTS STATE BUILDING CODE 

CHAPTER 7 - FIRERESISTANT MATERIALS AND CONSTRUCTION 

(Fipi Edition Article 9) 
DifTerences from the National Code: 
Chapter 7 is entirely compatible with the national code. 

Changes from the Fifth Edition of the Massachusetts State Building Code : 

Fireresistance rating of construction materials were located in Article 9 of the Fifth Edition. Along with 
location, several changes have occurred in the code text. Examples of change are found in Section 708.0 
which limits opening sizes in fire wall assemblies. Section 713.0 which defines minimum fire resistance 
ratings for floor\ceiling and roofVceiling assemblies in certain residential buildings, Section 717.0 which 
determines approval of fire dampers, and fire damper ratings, and 720.0 which requires the installation of 
firestopping and draftstopping. 

CHAFFER 8 - INTERIOR FINISHES 

{Fifth Edition Article 9) 
DifTerences from the National Code: 

Chapter 8 is entirely compatible with the national code. 

Changes from the Fifth Edition of the Massachusetts State Building Code : 

Interior finishes were part of Article 9 in the Fifth Edition under Seaions 922.0 through 925.0. Since 
interior finishes can have a significant effect on a building's internal fire load. These provisions are 
separated in the Sixth Edition to emphasize the importance of properly regulating the placement of 
combusuble trim, floor finishes, and interior hangings and decorations. Additionally, Section 806.0 limits 
the use of combustible materials in Types 1 and 2 construction. Chapter 8 should be utilized in concert 
with the provisions of 527 CMR, The Massachusetts Fire Prevention Code. 

CHAPTER 9 - FTRE PROTECTION SYSTEMS 
{Fifth Edition Article 10) 
Differences from the National Code: 

The provisions of Chapter 9 were developed by the Fire Prevention\Fire Protection Advisory Committee 
whose make-up is defined in the forward of the code. 

Chapter 9 is significantly different than the national code and is considered unique to the Commonwealth, 
particularly in its requirements for fire suppression systems. Section 904.0 identifies where fire 
suppression systems are required in buildings based upon the building's size and use group classification. 

Recognizing inherent life safety hazards posed by certain building types, and further recognizing the 
tremendous loss due to fire that has occurred in certain building types over the years, the Sixth Edition of 
the code requires fire suppression systems to be installed in buildings at levels not anticipated by the 
nauonal code. For instance Section 904.2 of the national code, allows an assembly use, such as a motion 
picture theater, to be erected unsuppressed up to 12,000 square feet. The comparable Sixth Edition section 
requires a fire suppression system to be installed when it exceeds 8,000 square feet. 

Also, Chapter 9 does not recognize the termftre area, which is often used in the pages of the national code. 
The term fire area is defined as "the aggregate floor area enclosed and bounded byftre walls, exterior 
walls, or ftre separating assemblies". Utilizing this concept in the design of mixed use buildings (Section 
313.0 of the code) allows the code user to design and erect buildings that sacrifice fire suppression for fire 
resistive construction. Essentially, the result of such a design is a building that is (or may be) suppressed 
in one area, but not another. Such buildings may provide a false sense of security for the occupant, and 
cause logistical problems for fire service personnel who must fight the fire (ie: the firefighter does not 
necessarily know which portion of the building is fitted with a suppression system, and which is not; a fact 
he needs to know to adequately fight the fire or deal with the emergency). This is not to say that separated 
mixed used buildings are not an option under the new code. However, once the size of a building exceeds 
a certain dimension (dependent upon its use group), a suppression system is required, regardless of whether 
the uses are separated from one another with fireresitance rating construction, which may render the 
separated mixed use option irrelevant.

USERS' GUIDE 

Changes to Chapter 9 are the result of many months of review of the national code. Some of the reasons 
for change are identified above. However, there are additional benefits to both the code user and the 
building occupant resulting from these changes. It is wonh noting that many municipalities in the 
Commonwealth experience some difficulty developing and maintaining a properly staffed fire department, 
and are often challenged in fighting larger fires. With the changes in fire suppression requirements, some 
of the burden may be lifted from these departments. 

Changes from the Fifth Edition of the Massachusetts State Building Code: ' 

Chapter 9 has not only been relocated in the Sixth of the code, but has also been significantly changed in 
technical content. The format of Chapter 9 t^es a more sobering look at issues of fire suppression and 
alarming and presents requirements in a more concise and logical pattern. It may be considered as 
diflFerent from Fifth Edition Massachusetts code as it is fi^om the national code. 

ARTICLE 10 - MEANS OF EGRESS 
{Fifth Edition Article 8) 
Changes from the National Code: 

Chapter 10 is nearly compatible to the national code. Changes appear in limited sections. 

The first change, an addition to the national code, occurs with the insertion of Section 1004.2 which 
empowers the building official to issue an exit order to a building owner when a hazardous egress 
condition is cited. Although this language is consistent with current practices in the Commonwealth, it 
is dififerent from the requirements of the national code. 

A second change occurs in Table 1010.3 of the code. Unlike the national code, the Sixth Edition only 
allows one means of egress from buildings in very limited instances (ie: use groups B and S-2 that meet 
ardent restrictions in terms of building size and occupant travel distance). 

A third change appears in Section 1017.4.1 pertaining to the locking of egress doors. Actually, the settion 
varies from the national code in two counts under this seaion. First, point number 8 under seaion 
1017.4.1 allows for the locking of certain doors in I-l and 1-2 occupancies when other life safety concerns 
are at issue. Second, Section 1017.4.1.2 allows for special locking arrangements in certain business 
occupancies when security issues conflict with code requirements. In each of these instances, the code has 
responded to building owner needs, carefijUy balancing issues of security and life safety without to either. 
When egress doors are locked under these provisions, additional life safety features are required. 

Additional changes are made to the provisions of Chapter 9 to ensure that it jibes with Massachusetts law 
and regulation. 

Changes from the Fifth Edition of the MassachusetU State Building Code: 

Many of the comments expressed above apply in respect to changes from the Fifth Edition Massachusetts 
code text. Means of egress requirements, in many instances, have changed and should be carefully 
reviewed by the code user. 

CHAPTER 11 - ACCESSIBILITY 

{Fifth Edition Section 512.0) 

Differences from the National Code: 

The provisions of Chapter 11 as they appear in the national code have been deleted. Chapter 11 in the 
Sixth Edition refers to 521 CMR. the Rules and Regulations of the Architectural Access Board (AAB 
regulations). The Architectural Access Board is empowered to promulgate these regulations under 
Massachusetts general law. Although it is a separate regulation under the control of a different agency, 
the provisions of the AAB regulations arc enforced by municipal and state building officials. The code 
user is cautioned that there may be significant differences from the national code, and should refer only 
to 521 CMR for regulations pertaining to building accessibility. 

Changes from the Fifth Edition of the Massachusetts State Building Code: 

Reference to AAB regulations appeared in Seaion 512.0 of the Fifth Edition of the code. See above 
comments for changes. 



780 CMR - Sixth Edition 



780 CMR: STATE BOARD OF BUILDING REGULATIONS AND STANDARDS 
THE MASSACHUSETTS STATE BUILDING CODE 

ARTICLE 12 - INTERIOR ENVIRONMENT 

[Fifth Edition - Article 7) 
DifTerencM from the National Code: 

Tht Sixth Edition of the code requires all newly constructed buildings to mechanically ventilate bathrooms 
and toilet rooms (natural ventilation of such spaces is not allowed as a substitute for mechanical 
ventilation). 

Access to attics and crawl spaces, if separating conditioned from unconditioned space, shall be weather- 
stripped and closed tightly. 

Changes from the Fifth Edition of the Massachusetts State Building Code: 

Bathroom mechanical ventilation requirements now include one- and two-family housing whereas the Fifth 
Edition of the code exempted one- and two-family housing bathrooms and toilet rooms from such required 
mechanical ventilation. 

Access to attics and crawl spaces, if separating conditioned from unconditioned space, shall be weather- 
stripped and close tightly. 

Rat-proofing requirements are now found in Chapter 12 

ARTICLE 13 - ENERGY CONSERVATION 

(Fifth Edition - Article 31) 
DifTerences from National Code: 

Chapter 13 of the Code does not yet require that new construction low-rise residential buildings conform 
to the requirements of the Council of American Building OfiScials (CABO) Model Energy Code, 1995 
version (MEC95). 

Chapter 13 will, however, require conformance to a Massachusetts version of MEC95 commencing 
March 1, 1998 - see front sheet of Chapter 13 and front of Appendix J. 

One- and two-family housing now explicitly requires thermostats for each floor containing conditioned 
space. 

Electrical outlet plate gaskets are now required on all receptacles, switch or other electrical boxes in walls 
separating conditioned from unconditioned space. 

Changes from the Fifth Edition of the Massachusetts State Building Code 

See "Differences from National Code" above. 

CHAPTER 14 - EXIERIOR WALL COVERINGS 

(Fifth EdMon Article 21) 
Differences from the National Code: 

Chapter 14 is entirely compatible with the national code. 
Changes from the Fifth Edition of the Massachusetts State Building Code: 

Changes made relative to provisions for exterior walls are in respect to its location in the code and changes 
reflecting technological advances in anchoring systems and building material combustibility. 

CHAPTER 15 - ROOFS AND ROOF STRUCTURES 
(Fifth Edition Artide 23) 
Differences from the National Code: 

Chapter 15 is entirely compatible with the national code, except, generic language referring to climaaic 
conditions not relevant to the Commonwealth have been deleted. 

Changes from the Fifth Edition of the Massachusetts State Building Code: 

Changes made relative to provisions for roof and roof structures are in respect to location in the code and 
changes reflecting technological advances.

USERS' GUIDE 

CHAPTER 16 - STRUCTURAL LOADS 

{Flfih Edidon Article 11 ) 
DifTerences from the National Code: 

The provisions of Chapter 1 6 were reviewed and further developed by both the Ljoads and the Seismic 
Advisory Committees whose make-up are defined in the forward of the code. 

Wind load provisions have been simplified; snow load zones are considered unique to Massachusetts; the 
use of importance factors for snow load design is not utilized, seismic design is based on a peak velocity 
related acceleration (a,) of 0.12 throughout the entire state; superfluous requirements dealing with loading 
criteria outside Massachusetts have been deleted. 

Changes from the Fifth Edition of the Massachusetts State Building Code : 

Seismic deign has been amended to reflect current design philosophy. 

CHAPTER 17 - STRUCTURAL TESTS AND INSPECTIONS 

( Fifth Edidon Article 13 ) 
Differences from the National Code: 

The provisions are similar to the national code but are enhanced by requiring a specific program of testing 
and inspections of critical structural items to be developed by the Structural Engineer of record. 

Changes from the Fifth Edition of the Massachusetts State Building Code: 

This chapter has been clarified to identify critical inspection procedures for structural materials and 
processes and fiirther serves to clarify some of the responsibilities of registered professionals under 
construction control (Sth edition section 127 - 6th edition sertion 116) 

CHAPTER 18 - FOUNDATIONS AND RETAINING WALLS 

{Fifth EdMon Article 12 ) 
The provisions of Chapter 18 were reviewed and further developed by the Geotechnical Advisory Committee 
whose make-up is defined in the forward of the code. The following is a detailed analysis of the their work 
provided by members of the committee. 

(1) For the Sixth Edition, the format, terminology and provisions of BOCA (1993) were usually adopted; 
the technical provisions are generally consistent with those in the Fifth Edition of the Massachusetts State 
Building Code, unless noted in the User's Guide. The User's Guide indicates the specific locations of 
significant changes which have been incorporated in the Sixth Edition, together with comments and backup 
information. Such changes include: 

(a) Technical changes to existing pro%asions, which may or may not be consistent with BOCA. 

(b) New provision.'; which have been adopted by the State Board of Building Regulations and 
Standards since issuance of the Fifth Edition (1990). 

(c) New provisions which are included in BOCA, but were not contained in the Fifth Edition. 

(d) New provisions which are introduced in the Sixth Edition. 

All references herein to BOCA are to the BOCA National Building Code, 1993 {Twelfth Edition). 

1802.0 FOUND ATIONINVESTIGATIONS 

1802.1 Where required- 1202.1 (Fiflh Ed.) retained; BOCA requirements for specific number of borings 

for building area not adopted. 

1802. V.I Seismic investigation- criteria established for field investigation/report on evaluation of 

"liquefaaion" potential, with reference to Seaion 1805.3 (1612.3 in the Fifth Ed.) 

1802. 2 Soil samples and boring reports: provisions of 1202. 2 (Fifth Ed.) retained, which require that 

copies of the results be filed with the code official. 

1803.0 SOIL BEARING TESTS 

1803.0 Soil bearing tests- all of 1203.0 (Fifth Ed.) retained, in lieu of 'Soil test procedure'.

THE MASSACHUSETTS STATE BUILDING CODE 

1804.0 LOAD BEARING VALUE OF SOILS 

18Q4 1 Soik repon- 1201.3.2 (Fifth Ed.) provisions retained; BOCA list of requirements for prepared 
fill in report are not included. 

1804.2 Satisfactory foundation material.<;- 1201.2 (Fifth Ed.) retained. 

1804.3 Presumptive load hearing values' 1201.3 (Fifth Ed.) provision for approval of higher bearing 
pressures retained, and 1201.3.1 reference to Appendix for guidelines for classification of bearing 
materials retained. 

TABLE 1804.3 Allowable Bearing Pressures, has been retained from the Fifth Ed. (TABLE 1201) with 

some minor modifications. 

The values in BOCA (TABLE 1804.3) are considered inappropriate for Massachusetts. 

1201.3.2 {Fifth Ed.) provisions for compacted fill below foundations and for field control are retained. 

1804.4 Light weipht structures- 1201.3 (Fifth Ed.) retained. 
1805.0 ALLOWABLE FOUNDATION LOADS 

1805.2 Soil capacity- Provision added, which allows up to 33% increase in bearing pressures for soil 

types indicated, for load combinations which include wind or seismic. This provision applies to all 

foundation types. A similar provision in the Fifth Ed. (1206.2) that applied only to footings has been 

deleted. 

1805 3 Liquefaction- These provisions have been transferred in their entirety from 1 1 13.8 (Fifth Ed,). 

1805 4 Vertical pressure- 1204.4 (Fifth Ed.) retained. 

1805.5 Settlement analysis- 1204.5 (Fifth Ed.) reuined,' 

1805 6 Disturbance of hearing soils- 1204.6 (Fifth Ed.) retained. 

1805 7 R ock foundations- provisions added for increased bearing pressures, based on load tests (per 
BOCA). 

1806.0 DEPTH OF FOOTINGS 

1806 1 Frost Protection- modified to apply to structures larger than 100 sq. feet area or 10 feet high (per 
BOCA). 

1806.2 Isolated footing- The criteria for relative position of soil-bearing footings changed, consistent 
with BOCA (See 1205.2, Fifth Ed.). 

1806.3 Dept h of spread footings- 1205.3 (Fifth Ed.) retained. 
1807.0 FOOTING DESIGN 

1807 1 Design loads- 1206. 1 (Fifth Ed.) retained. 
1807 4 F.rr.pntrir. loads- 1206.6 (Fifth Ed.) retained. 

1810.0 CONCRETE FOOTINGS 

18 10.2. 1 Footing seismic tips- Requirements for seismic ties between fooungs for Category D structures 
have been added consistent with BOCA (1810.2. 1). These provisions dififer from BOCA in that the ties 
are to be designed for a force equal to 10% of the larger column dead load plus live load in lieu of "a 
force equal to 25% of the effective peak velocity-related acceleration (A,) times the column dead load 
plus live load". Under 1 1 13.6.9 (Fifth Ed.) interconnettions of footings with ties were not specifically 
required, but were to be considered in the design. 

1812.0 FOUNDATION WALLS 

1812.2 Definitions and 1817- 3 Minimum thickness- definitions have been added and requirements 
modified from those of 1222.2 (Fifth Ed.); also. Table 1812.3.2 has been changed. 

1812.6 T^ateral stahilitv- there is an added reference to 1825.0 for seismic design requirements. 
1814.0 MAT RAFT AND FLOAT FOUNDATIONS 

1814.2 Settlement analysis- the requirement for a settlement analysis (121 1.2, Fifth Ed.) is retained. 
1815.0 PIER FOUNDATIONS 

1815 1 General- The definitions, as given in 1212.1 (Fifth Ed.) are retained but with modifications: 1) 
"and piles installed by the hollow stem auger method" is deleted (refer now to 1 820.2) and 2) "other 
non-circular foundation elements" are now included. 



780 CMR - Sixth Edition 



780 CMR: STATE BOARD OF BUILDING REGULATIONS AND STANDARDS 

USERS' GUIDE 

1815 2 1 Foundation tie?;- the provisions for interconnection between piers are consistent with BOCA 
(1815.2), except that the ties are to be designed for a force equal to 10% of the larger column dead load 
plus live load in lieu of "a force equal to 25% of the effective peak velocity-related acceleration (A,) 
times the column dead plus live load". (This in effect retains the requirement in 1 1 13.6.9 (Fifth Ed.) 
for interconnection of piers, with a similar magnitude of design force in the tie, which is more 
conservative than BOCA.) 

1815.2.2 Seismic reinforcement: these new provisions are similar to those now required for cast-in- 
place concrete piles (see 1 820. 1.2.1). The provisions in 1 820. 1 .2. 1 which were adopted by BOCA, are 
consistent with the model code provisions issued by FEMA {NEHRP Recommended Provisions for 
Seismic Regulations for New Buildings, 1994 Edition, prepared by the Building Seismic Safety Council 
for the Federal Emergency Management Agency). Although BOCA does not require seismic 
reinforcement for piers, it is noted that the FEMA guidelines recommended that the same seismic 
provisions apply to drilled piers or caissons. Therefore, such provisions are included herein. Note that 
the "minimum pier design cross seaional area" is defined as the minimum seaion area, as determined 
by the allowable design stresses, even though the actual pier section may be larger. 

1815.2.3 Pier cap connection- the provisions are similar to those now required for all concrete piles 
(1816.11.1) which are consistent with the FEMA model code provisions (see 1815.2.2 for reference). 
Although BOCA does not require the cap connection for piers, such provisions are included herein for 
consistency with the FEMA recommendation. 

1815.24 Alternative detailing- This provision allows alternatives to the code-specified minimum 
reinforcing, similar to the BOCA provision for concrete piles in 1816.11.1. 

1815.3 through 1815 11- The existing provisions, in 1212.2 through 1212.10 (Fifth Ed.) are retained; 
they are considered more complete and appropriate for Massachusetts. 

1816.0 PILE FOUNDATIONS 

1816.3 Pile bending seismic design- The special provisions of BOCA (1816.3) were adopted for pile 
reinforcement below buildings assigned to Seismic Performance Category D; this was not required in 
the Fifth Edition. It is noted that this is consistent with the FEMA document referenced in 1815.2. 

1816.4 Protection of pile materials- the existing provisions, 1213.3 (Fifth Ed.) are retained; they are 
considered more complete and appropriate for Massachusetts. 

1816.5 T.aterai support- 1213.4 (Fifth Ed.) is retained; reference to "fluid soil" is deleted. 
1816.7 Stahilitv- 1213.6 (Fifth Ed.) is retained. 

1816 8 Stnictural integrity- 1213.7 (Fifth Ed.) is retained. 

18 16.10 Splices- 1213.9 (Fifth Ed.) retained, including requirement for all pile splices to "develop at 
least 50% of the capacity in bending". In addition, the BOCA provisions for design requirements for 
splices located in the upper ten feet of the embedded pile are adopted. 

1816 1 1 1 Pile cap seismic connection: The special provisions of BOCA (1816.11.1) were adopted for 
seismic conneaion of all concrete piles to the caps (not required in Fifth Ed.). Note: This is a new 
requirement, which may have an economic impact on pile foundations. 

1816 11 2 Pile foundation seismic ties- The provisions for interconneaion between pile caps are 
consistent with BOCA (1816.1 1.2), except that the ties are to be designed for a force equal to 10% of 
the larger column dead load plus live load in lieu of "a force equal to 25% of the effective peak velocity- 
related acceleration (A^) times the column dead plus live load". (This in effea retains the requirements 
in 1 1 13.6.9 (Fifth Ed.) for interconnection of pile caps; the magnitude of the design force in the tie is 
more conservative than BOCA.) 
1816 n Inspection- The more detailed requirements of 1213.12 (Fifth Ed.) are retained. 

1816 18 Pi le Heave- The more detailed requirements of 1213. 17 (Fifth Ed.) are retained. 
1817.0 ALLOWABLE PILE LOADS 

1817 1 through 1817 3- Thp existing provisions in 1214.1, 1214.2 and 1214.3 (Fifth Ed.) including the 
requirements for determination of allowable load by the driving formula, friction formula in clay and 
for jacked piles, are retained. (Note: The description of the design criteria for friction piles in clay has 
been modified for clarification. 

1817.4 Compression load tft^- The existing provisions in 1214.4 (Fifth Ed.) are retained; they are more 
detailed and appropriate for local conditions. 

1817 6! .ateral load tg^ts and 1817.7 Tension Load tests- The more detailed existing provisions, of 1214.6 
and 1214.7 are retained.

THE MASSACHUSETTS STATE BUILDING CODE 

1817 8 Bearing capacity The existing provisions of 1214.8 (Fifth Ed.) are retained. 
1818.0 STRUCTURAL STEEL PILES 

181S 2 Allowahle streps' The existing provisions in 1215.4 (Fifth Ed.) are retained, including the limit 
of "35% of the minimum specified yield strength or 12,600 psi." The limitation on stress is a result of 
driveability considerations. 

1818 3 Pile cap seismic connection- The special provisions of BOCA were adopted for connection of , 
steel piles to the caps for buildings assigned to Seismic Category D, (not required in the Fifth Edition). 

1819.0 CONCRETE-FILLED STEEL PIPE AND TUBE PILES 

1819.2 Allowahle stress- A distinction is made between top-driven and mandrel-driven piles; 

- In 1819.2.1, the existing provisions in 1216.3 (Fifth Ed.) for stress limits due to driveability 
considerations are retained for top-driven piles. 

- In 1819.2.2, the higher allowable limits in BOCA are allowed for piles driven by mandrels which 
effectively transtnit the driving stresses to the bottom of the pile. 

18193.1 Pile cap seismic connection : The special provisions of BOCA were adopted for pile 

reinforcement and connection to the cap for all piles (not required in the Fifth Ed.). 

1819.5 Placing concrete- the existing provisions in 1216. 1 (Fifth Ed.) for alignment criteria of the steel 

pipe before filling with concrete have been deleted; the reason is that other pile types which cannot 

be similarly inspeaed are not subjea to such requirements, and such requirements are not generally 

necessary. 

1820.0 CAST-IN-PLACE CONCRETE PILES 

1820.1.1 Material- The existing requirement, 1217.1 (Fifth Ed.) for minimum concrete strength is 
retained (i.e. 3000 psi in lieu of 2500 psi in BOCA) 

1820.1.2.1 Seismic reinforcement- The special requirements of BOCA (1820.2.2.1) for pile 
reinforcement and connection to the cap are adopted (Not required in Fifth Ed.). Note: There are 
di£ferent requirements for buUdings assigned to Seismic Performance Category C and D. 

1820.1 3 Installation- the installation requirement for all cased, concrete-filled piles are given here, and 
are referenced in 1820.4.3.2.3 and 1820.5.3. 

1820.2 Angered uncased piles- The provisions are now in a new, separate section; this pile type was 
previously (Fifth Ed.) included in 1212.0 Pier foundations. The provisions have been modified, and are 
not entirely consistent with BOCA (1820.2). 

Note- 1820.2.8 Instrumentation has been added; it requires that the auger rig be equipped with data 
logging equipment to automatically record vital information during installation. 

1820 4 Pressure-JTijected footings- All provisions are those contained in the REVISIONS to 1217.0 
(Fifth Ed.) which were adopted since issuance of the Fifth Edition (1990). The revisions, together with 
an extensive Commentary, were prepared by the Geotechnical Advisory Committee and presented at 
a Public Hearing on November 30, 1993, and were subsequently approved and filed by the State Board 
of Building Regulations and Standards. 

1820.5 Cased poured concrete piles- The existing provisions in 1217.5 (Fifth Ed.) have been retained, 
including the limitation of 1,600 psi on design stress. 

1820.6 Small diameter grouted piles- These provisions for grouted cast-in-place piles, less than 12 
inches diameter, are not included in BOCA (1993). The requirements of 1217.2 (Fifth Ed.) have been 
re-organized and retained. 

1821.0 PRECAST CONCRETE PILES 

1821.1 through 1821. 3- The BOCA provisions are generally adopted. In 1821.33, the formula for 
design compressive stress varies slightly from that in 1218.3 (Fifth Ed.) i.e., a smaller deduaion is 
required for the prestress. The 1600 psi limitation on design stress in the Fifth Ed. has been retained. 

1821 3 5 Pile cap seismic connection- The special provisions for seismic connection (per 1816.1 1) 
also allows for extension of the pile reinforcing strand into the cap, except for buildings assigned to 
Seismic Performance Category D. 

1821 3 6 S piral seismic reinforcing- Special BOCA provisions for the length of spiral reinforcement for 
buildings assigned to Seismic Performance Category D are adopted. Also, the requirements for ties in 
the upper two feet of pile have been added, to be consistent with FEMA.

been adopted since issuance of the Fifth Edition (1990). 

The Revisions, together with an extensive Commentary, were prepared by the Geotechnical Advisory 
Committee and presented at a Public Hearing on November 8, 1994, and were subsequently approved 
and filed by the State Board of Building Regulations and Standards. 

1824.0 CONCRETE-FILLED STEEL PIPE WITH STEEL CORE CAISSONS 

1824.2 Rock- socket- The provisions for the rock socket design have been revised to require that the 
perimeter bond stress be determined by studies for each installation, but in no case shall the bond stress 
exceed 200 psi. Also, the minimum outside diameter has been reduced fi-om 24 to 18 inches, consistent 
with BOCA. 

1824.3 Seismic reinforcement: It is required that all caissons have seismic reinforcement, per 1 820. 1.2.1 
(not in Fifth Edition) 

1824 6 Allowable stress: BOCA provisions adopted, without the stress limits on concrete and steel as 
contained in 1221.8 (Fifth Ed.); such limits do not apply, since the caisson is not driven. 
1824 S Precautions- The requirement for plumbness (1221.6 Fifth Ed.) has been deleted. 

1825.0 RETAINING WALLS 

1825.2 Design- Design requirements to resist seismic loads have been added.
