APPENDIX F

ARCHITECTURAL AND ENGINEERING GUIDELINES

This memorandum will summarize the basic requirements of the sixth edition of the Massachusetts State Building Code (MSBC) applicable to the building at ▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇. It includes the conditions imposed by MSBC Appeal Board in its decision to permit the roof trusses of the building to remain without fire rating.

Basic Building Code Requirements

The basic requirement of the MSBC applicable to this building are summarized in Table No. 1. The occupancy and building characteristic that are the basis for those requirements are identified at the beginning of that table. Any deviation from those characteristics including changes of occupancy must be made in compliance with the building code and the intent of the variance which was granted with respect to the roof assembly.

Conditions on the Variance

Two sets of conditions have been imposed on the design and construction of the building in order to justify the variance to permit the roof trusses and deck to be unrated. These are in addition to the standard features of the building required by the building code based on its occupancy and physical characteristic. Those requirements are summarized in Table No. 1.

First, in the presentation of technical arguments for the variance, it was represented that the following fire protection features would be provided in the building:

One connection to the site water mains which are supplied from the Watertown municipal water system.

A fire pump to boost system pressures to required levels.

A standby power supply for the fire pump.

A system of combined standpipe risers to supply sprinkler systems of each floor as well as hose connections within exit stairs.

Three sprinkler systems per floor with each arranged to be supplied from two separate standpipes.

Complete supervision of all operation characteristics and components of the sprinkler and standpipe systems.

Complete coverage of all levels of the building with automatic smoke detectors.

All of these features have been provided as part of the base building except that tenant sprinkler systems must be arranged to be supplied from two separate standpipes and tenant space fire alarm systems must include complete coverage with an addressable automatic smoke detection system for all floors.

Second, two conditions were imposed on the fourth floor of the building by the Appeal Board in its decision. One condition requires that ceilings, where provide, have a one hour fire rating. This requirement may be applicable to fully enclosed offices, toilet rooms, storage rooms, equipment rooms and similar spaces which are provided with ceilings suspended or framed below the roof trusses. The decision also required that sprinklers be installed both above (in the truss space) and below the ceilings (in the use space), where ceilings are provided.

The requirement for a one hour ceiling may be satisfied by installation of a ceiling assembly which has a one hour “finish rating” by standard Underwritten Laboratories’ test criteria. Such a ceiling will typically require two layers of 5/8 inch Type X gypsum-board appropriately attached to framing above. The ceiling membranes of UL Floor/Ceiling Assembly Design No. L532 or L505 would be appropriate for this purpose. The intended fire rating will only be achieved if the ceiling membrane is provided with connections and support equal to that provided by the floor assembly to which it is attached in the UL Design (ie. Spacing of framing, frequency of fastener, etc.).

Floor Systems

2. Provide 2 hour fire ratings for floor/ceiling assemblies as required for construction Type 1B. (T-602).

3. Provide multiple floor openings arranged as an atrium having features as summarized in Table No. 1. (713.3, Exception 5, 404.0)

Interior Walls and Partitions

4. Provide unrated partitions for enclosure of exit access corridors. (1011.4)

5. Provide one hour rated partitions as tenant-to-tenant separation walls. (T-602).

6. Provide two hour fire enclosures for stairway, elevator and mechanical shafts which connect more than three stories and one hour fire rated enclosures for stairway and mechanical shafts which connect three stories or less. (T-602, 1014.11, 710.3)

7. Provide two hour fire rated enclosures of all rooms, shafts and closets containing equipment and wiring for emergency power generation, distribution and control. (MA Electrical Code, 700-10).

8. Provide one hour fire rated walls with ³/4 hour opening protective around the following specific occupancy areas:

•

Trash rooms

•

Physical Plant and Maintenance Shops (302.1.1, T-302.1.1)

9. Provide smoke partitions designed to resist the passage of smoke constructed of combustible or non-combustible materials which extend from the floor below to the underside of the floor or roof above around the following specific occupancy areas:

•

Storage rooms over 50 sq. ft. in area (302.1.1, T-302.1.1)

10. Provide doors to the areas identified in Item 9 which are self closing or arranged for automatic closing upon detection of smoke. (302.1.1.1)

Exterior Walls and Roof

11. Provide three hour fire ratings for interior and exterior columns supporting more than one floor and two hour fire ratings for columns supporting only one floor or the roof. (T-602).

12. Provide unrated non-bearing exterior wall components for the building walls. (705.2, T-705.2).

13. Utilize unlimited openings in exterior walls. (705.3, T-705.3).

No rating is required for exterior walls of a sprinklered building of use Group B occupancy when the fire separation distance for the wall is greater than 5 feet. Unlimited exterior wall openings are permitted in such a wall when the wall has a fire separation distance of more than 20 feet.

The fire separation distance of the Arsenal Street wall measured to the centerline of Arsenal Street is 48 feet. The fire separation distances of walls not facing immediately adjacent buildings are well in excess of 20 feet.

The physical distance between building 311 and the Harvard Printing Building is approximately 37 feet. A fire separation distance of greater than 15 feet for the Harvard Printing Building permits that budling to have an unrated exterior wall with not more than 70% openings. The remaining 22 feet is considered the fire separation distance for Building 311. That distance allows the unrated exterior wall with essentially 100% openings that are provided on Building 311.

The physical distance between Building 311 and the adjacent parking garage is approximately 55 feet. That physical distance permits a fire separation distance of greater than 30 feet for the parking garage and greater that 20 feet for Building 311. In that situation, the exterior wall of Building 311 is permitted to be unrated and have unlimited exterior openings.

14. Do not provide fire rated exterior walls for exit stair enclosures or for the exterior walls of use spaces adjacent to exterior walls of exit stairs. (Compliance alternative 1014.11.1).

MSBC Section 1014.11.1 requires that either the exterior walls of exit stair enclosures have a one hour rating and have protected openings of that the exterior walls of adjacent use spaces within 10 feet of the stair enclosure be treated in that manner.

As a compliance alternative to strict compliance with the requirement for exterior wall rating and opening protectives wither within or adjacent to an exit stair, close spaced automatic sprinklers will be provided to protect the exterior glass of the stair enclosure. Those sprinklers will help to maintain the integrity of the stairway windows under potential fire exposure.

15. Do not provide opening protection for any exterior wall openings in this fully sprinklered building. (705.3.1).

16. Do not provide a fire rated spandrel panel or wall on this fully sprinklered building. (705.4, Exception 2).

Fire Alarm System

17. Provide a fire alarm system having the basic features required by Section 917 and additional features required by the atrium Section 404.0. (917.4.2).

18. Provide addressable system connected automatic some detectors throughout all levels of the building. (NR/Condition of variance).

Complete coverage of the building with addressable type smoke detectors was offered as part of the justification of the requested variance from fire rating requirements applicable to the roof assembly. Such protection is considered a condition of the variance.

19. Activate the fire alarm system using manual pull stations, water-flow detectors of the sprinkler system and smoke detectors of the atrium exhaust system. (917.7.1).

Means of Egress

20. Provide 2 doors to the corridor system from all rooms or spaces with an occupant load of more than 50 persons or in which the travel distance exceeds 75 feet. (T-1017.2).

21. Install doors which serve rooms with occupants loads of 50 or more persons so as to awing in the direction of egress travel. (1017.4).

22. Where two exit or exit access doors are required from a room or other space, separate the doors by a distance equal to or greater than one quarter of the longest diagonal of the area served. (1006.4.1)

23. Limit dead ends of corridors to not more than 20 feet. (1011.2).

24. Limit the length of a common path of travel in the Use Group B spaces to not more than 100 feet. (1011.2.1).

25. Provide unrated exit access corridor enclosures. (1011.4.).

26. Provide unrated corridor doors. (1011.4.2).

27. Provide corridors with a minimum clear width of 44 inches. (1011.3).

28. Utilize interior exit stairs designed in accordance with MSBC Section 1014.0 as the required exits of the building. (1014.0).

29. Provide sufficient egress capacity for the occupant load of each floor of the building separately. (1009.1, 1009.3).

At the code specified area allowance of 100 square feet per person and with an area of not more than 147,000 square feet, the occupant load of the largest floor of the building will be 1,470 persons. There will be four 44 inch wide exits stairs and seven 48 inch wide exit stairs provided from the upper stories of the building will each have a capacity of 220 persons. The total capacity available from those stairs at an allowance of 0.20 inches per person will be 2,560 persons, well in excess of the project population.

30. Locate exits as required to limit travel distances to less than 150 feet in spaces not separated from the atrium and 250 feet in spaces separated from the atria. (404.7, T-1006.5).

31. Provide exit discharge from exit stairs directly to the outside, through rated passageways, sprinklered lobbies or small vestibules. (1020.0).

Elevators

32. Provide all elevators having a travel of 25 feet or more with characteristics and controls for fire emergency use in accordance with the MA Elevator Code. (MA Elevator Code, 17.39).

33. Provide one elevator which serves all floors of the building with characteristics and controls to permit emergency medical use in accordance with the MA Elevator Code. (MA Elevator Code, 17.40).

Sprinkler Systems

34. Provide a complete automatic suppression system in all portions of the building in accordance with the requirements of Article 9. (904.2, 404.2).

Standpipe

35. Provide fire standpipes in the building with hose connections located in accordance with the criteria of NFPA 14. (914.4, 914.5).

Water Supply

36. Provide water supplies for the sprinkler and standpipe systems using a connection to the municipal water supply. (NFPA 13, 14).

37. Size the supply piping of the combined sprinkler and standpipe water supply system in accordance with the criteria of NFPA 14. (914.3).

38.

Provide connections of each sprinkler system to two separate standpipe risers. (NR/Condition of variance).

Emergency Power

39. Provide an emergency generator to provide standby power for the fire alarm system, exit signs, emergency lights, the atria smoke control systems and the fire pump. (917.6, 1023.4,1024.4, 921.5, Condition of variance).

The provisions of standby power for the fire pump was a condition of the variance from the requirements for the fire rating of the roof assembly.

Interior Finish

40. Utilize interior finish as follows:

•

Class I interior finish within all exit stairs.

•

Class II or better interior finish within all exit access corridors serving only office areas.

•

Class III or better interior finish within rooms or spaces of assembly and office areas. (T-803.4).

41. Utilize traditional floor coverings such as wood, vinyl, linoleum, terrazzo or other resilient floor finish material or carpeting which complies with the DOC FF-1 “pill test” (CPSC 16 CFR, Part 1630) in all spaces including exits and exit access corridors. (805.3, Exception).

TABLE NO. 1

Summary of Atrium Requirements

Massachusetts States Building Code — Sixth Edition

1	Classify any openings in the floor systems connecting two or more stories as an atrium. (404.1).

2	Provide a complete automatic suppression system in the portions of the building not separated from the atrium by two hour fire separation partition and floor assemblies (404.2).

3	Limit the use of the floor of the atrium low hazard uses with approved materials and decorations unless appropriately protected with automatic fire suppression system. (404.3).

4	Allow exit discharge through the atrium in accordance with the rules for exit discharge through a lobby in Section 1020.0. (404.3.1).

5	Provide a smoke control system as required by Section 921.0. (404.4)

6	Separate the atrium from adjacent spaces by 1-hour fire separation walls, fire rated windows or tempered, wired or laminated glass walls constructed as required by Section 404.5 [Exception 2] except as noted in Item 7 below (404,5).

7	Allow up to three levels of the building to be open to the atrium without the separation required by Item 6. (404.5, Exception 3).

Only limited portions of the First Floor of the building will be open to the atrium. Most spaces will be separated from the atrium spaces by glass walls protected by closely spaced sprinklers.

8	Provide automatic smoke detectors within and at the perimeter of the atrium and on the ceilings of spaces not separated from the atrium (404.6.)

The extent of coverage by smoke detectors is not explicitly stated in the code. Coverage should be provided in the area immediately surrounding the atrium and all corridors which are open to the atrium. The specific extent of coverage should be determined in discussions with the authorities having jurisdiction.

9	Arrange automatic smoke detectors within the atrium space to sound fire alarms upon activation of an two or more of the detectors. (Not required).

No explicit requirement that two or more smoke detectors be required to operate before fire alarms are sounded is found in the current edition of the code. However, that means of operation is one reasonable approach to limiting the effect of false alarms from smoke detectors (Such a requirement did appear in previous editions of the NBC.) Other technical approaches to limiting the false alarm problem are available such as addressable detectors and alarm confirmation circuits. The specific arrangement of the detection system in this facility should be determined in discussions with the authorities having jurisdiction

10	Activate the fire alarm system using signals from sprinkler system water-flow detectors and manual pull stations. (406.6, 917.7,1).

11	Utilize a voice or non-voice alarm system which complies with the detailed provisions of Section 917.9. (404.6)

12	Limit the distance of exit access travel within the atrium on other than the lowest levels of the building to not more than 150 feet. (404.7).
