780 CMR, The MA Building Code Look at the table of contents Chapter
4: SPECIAL USE AND OCCUPANCY Chapter 6: TYPES OF CONSTRUCTION Chapter 8: INTERIOR FINISHES Chapter 9: FIRE PROTECTION SYSTEMS Chapter 10: MEANS OF EGRESS Chapter 11: ACCESSIBILITY Chapter 12: INTERIOR ENVIRONMENT Chapter 13: ENERGY CONSERVATION Chapter 34 REPAIR… AND CHANGE OF
USE OF EXISTING STRUCTURES
Building Code Analysis1. Gather general building data
(construction Type, Use Group, etc.)2. Calculate occupancy load based on
Specific Use 1. Plan with shaded areas2. Chart with calculations
3. Analyze egress system 1. Calculate capacity of corridors, doors, and
stairs2. Life Safety Diagram (Max. length of egress
travel, separation of exits, fire rated partitions)
3. Compartmentalization diagram
Step 1: Gather general data
What is the “Use Group” of the building (Museum) and this project (A3)?
What is the building “Construction Type” (IIIB - unprotected)?
Will project be sprinklered throughout (yes)?
What are partition and floor ratings?
General Data Example
Miscellaneous definitions
Step 2: Calculate occupancy Use chart in code for Specific Occupancy
Areas (fig.1004.1) to assign rooms Use Color Scheme for Occupancy – plan
will color in Sometimes need to adjust for circulation
(subtract 35% from total), actual use Chart in Revit is APPROXIMATE, but OK for us For real life, study exact areas
Place Occupant load in chart to calculate
Occupancy plan
Use a key for specific uses
Other information can be shown
OCCUPANCY ANALYSIS
LEVEL 2
LEVEL 1
Use spreadsheet:
For detailed analysis, add line for each
room; for THIS
project, just use total from
Revit, adjusted for circulation
Results for egress
components
Check codes!
Life Safety DiagramMaximum length of
egress travel: 120’ (250’ allowed)
Actual separation of exits: 149’ (102’ min.
allowed – 1/3 diagonal)

Interior Partition Construction
Interior Partitions
Common structural materials:• Steel studs (commercial)• Wood studs (residential)• Concrete masonry units (CMU)• Poured in place concrete
Common facing materials:• Gypsum board• Plaster• Glass-reinforced gypsum (GRG)

Partition Types: choose/create each one
• Show floor and ceiling condition in section• Indicate all materials with lines/hatching and notes• Typical options for different interior partition types:
– Wood vs. metal– 1-hour fire rated vs. 2-hour fire rated vs. non-rated– Dry vs. wet location– High impact resistance vs. standard– Degree of acoustical isolation– Finish systems
Metal non-rated walls
Rated construction
Shaft Walls
What about sound?
