State Building Code Review— 7`h edition Dear Mr. Mead: The following represents a summary of the applicable regulations of the Massachusetts State Building Code (7th edition) as they affect the above referenced project. It is based upon the Permit Set dated 2-1-11. This summary shall also be included as part of the building permit application via the General Contractor. Site Information and Setbacks Per Land Planning Inc. Property Ownership/Authorized Agent Genesis HealthCare, 200 Brickstone Square, Andover, MA 01810 Agent: Mr. Ray Mead, Senior Project Manager Construction Services - General Contractor: pending Worker's Compensation Insurance Affidavit Per General Contractor Professional and Construction Services Architectural: Jordan O'Connor&Associates, Jordan O'Connor, AIA#7655 MA Structural: Mr. Rob Johnson PE, Johnson Structural Engineering Inc., 30 Faith Avenue, Auburn, MA 1 Mechanical engineering: Mr. Kevin Seaman PE, Seaman Engineering Corp., 30 Faith Avenue,Auburn, MA Electrical engineering: Mr. Bob Figuerido PE, Shepherd Engineering Inc., 1308 Grafton Street, Worcester, MA Description of Proposed Work: A new single story new facility located on the first floor adjacent to an existing Nursing Home. The new facility is comprised of a new entry, waiting area, conference room, cafe, PT/OT therapy, speech,nurse/reception, shower/restroom and circulation space. The new facility shall be constructed directly adjacent to the existing facility and be structurally independent of the existing facilities. Per 705.1 the new facility is intended to act as a new independent facility and be separated from the existing facilities by a new rated fire wall. The new facility shall be installed with an automatic fire suppression system and be fully accessible to the disabled. Original facility: grade level: 17,325 sf first floor: 16,000 sf second floor: 11,360 sf third floor: 11,360 sf ---------------------------------- Total gross: 56,045 sf Maximum existing height=42'-0" New facility: first floor, slab on grade: 2,825 sf gross Maximum height (ie: average height of new canopy to average grade plane) = 17-69 +/- Number of stories: one (1) Use Group and Construction Type: Existing: The original facility was designed as a Nursing Home (use group I-2) for Nursing and Retirement Center of the Andovers (circa 1988). It is primarily composed of load bearing masonry walls with 8"thick concrete plank floors and roof. Existing sections indicate the use of fireproofing on all exposed internal structural steel. Based upon this it is assumed that the construction type is at least Type IIA. The facility is fully sprinklered and protected by a complete fire alarm system including horns, strobes and pull stations. 2 New Facility: The new facility, per Owner direction,is an I-2 use. As required per MGL 111 section 71 the type of construction shall be 1B.Note: The proposed cafe area is less than 750 sf and has an occupancy load of less than 50. Per 302.2.1 this space may remain classified as part of the I-2 use. In a similar manner the PT/OT+Kitchenette space is,per Owner direction, expected to have no more than 16 occupants at any one time. Although these two spaces total 796 sf net, which exceeds the 750 sf threshold set in 302.2.1, it is felt that the space is still consistent with an I-2 use due to the low occupancy load and large amount of therapy equipment. The office function is less than 10% of the new facility floor area and does not exceed that tabular values of height and area for a B-Business use (Per Table 503, B use,type IIB construction: 4 stories, 23,000 sf/floor max), OK. Applicable Codes 730 CMR Massachusetts State Building Code—7`h edition 248 CMR Massachusetts State Plumbing Code Current 1999 National Electrical Code 521 Massachusetts Architectural Access Regulations—latest edition Guidelines for Design and Construction of Hospital and Health Care Facilities—2010 527 CMR Board of Fire Prevention Regulations, latest edition Dept. of Public Health, Long Term Care Facilities, 105 CMR 1500.000-159.000 B. Accessibility Review: 3.2 All new construction of public building shall comply. 13.1 The new facility does not offer overnight accommodations as these accommodations are provided in the existing separated Nursing Home facility. Based upon this it is felt that the new facility, by way of offering discreet intervals of therapy/caf6, is more closely aligned with Doctor's and dentist's offices, counseling offices, offices of chiropractors,psychologists and psychiatrics and laces providing health services that do not require overnight accommodation. As such, per 13.1, the new facility falls under 11.00 Commercial Buildings. 11.4 The restrooms are open to the public and shall be accessible per 521 CMR 30.00 Public Toilets. 11.5 Public telephones are not provided. 11.6 Transaction area(ie: Nurse/reception) shall conform to 521 CMR 7.2.2 Other transaction areas. 3 7.2.2 The new Nurse/reception area shall be on an accessible route and have a portion of the counter be at least 36" long with a height no greater than 36" above finish floor. 22.00 23.00 Refer to civil engineering drawings. 24.1 A new exterior accessible sloped path shall be provided to connect from grade to main front entry. The slope of this path shall not exceed 1:20 and is,therefore not defined as a ramp. Note: the sloped path of egress shall accommodate the passage of a wheeled stretcher unit. 25.3 Entry air-locks shall be provided that complies with fig. 25a and is approachable to meet 25.2. 26.6 All doors shall comply with the required maneuvering clearances of this section. 27.1 New exterior stairs shall conform to the requirements of this section. A 48" clear width between rails shall be maintained. 29.1 Changes in floor finish thickness (typically carpet to vinyl tile) shall be via reducer strips that comply with the requirements of 29.2 and 29.3 30.1 New accessible restrooms shall be provided per the requirements of these sections. All requirements of Section 30 shall be followed.Note the tub in Toilet 109 shall be non-accessible by design and per Owner input in order to provide necessary rehabilitation. Note: A fully accessible shower unit shall be provided in the accessible shower room 105B. 32.1 The kitchenette in the caf6 will have an accessible height countertop with an accessible sink, refrigerator/freezer and storage. The range top shall not be open to the public (ie: locked out) and operated only by staff. A pantry unit shall not be installed due to the transient nature of the clients as well as the staff utilization of other onsite commercial kitchens for needed storage. The kitchenette in the MOT space is meant for rehabilitation therapy associated with non-accessible kitchen features. With the exception of an accessible sink all other features of the kitchenette(ie: storage, washer/dryer, dishwasher(verify with Owner), stove/oven, etc.) shall be by design and per Owner input, non-accessible. 4 33.1 The changing area shall provide accessible clearances including a bench, sink, storage and mirror to conform to the requirements of this section. 36.1 A drinking fountain or a water cooler shall not be installed per the Owner. 37.1 No public telephones are to be provided. 40.1 A fire alarm system shall conform to the requirements of this section. C. Building Code Review Chapter 3 302.2 The proposed cafe area is less than 750 sf and has an occupancy load of less than 50. Per 302.2.1 this space may remain classified as part of the I-2 use. In a similar manner the PT/OT+Kitchenette space is,per Owner direction, expected to have no more than 16 occupants at any one time. Although these two spaces total 796 sf net,which exceeds the 750 sf threshold set in 302.2.1, it is felt that the space is still consistent with an I-2 use due to the low occupancy load and large amount of therapy equipment. 308.3 Per Owner direction the facility shall be classified as I-2 although it's actual operation, as noted in 13.1 above, is more closely aligned with commercial buildings (ie: use group B-Business). Chapter 4 407.1 The I-2 occupancy shall comply with the provisions of this section and other applicable provisions of this code. 407.2 Corridors are continuous to exits(including horizontal exits). 407.2.2 Nurse/reception station shall be open to the corridor. 407.3 Corridor walls shall be constructed as smoke partitions (per section 710.3, non- rated)unless required otherwise. 407.3.1 Corridors, other than those required to be rated shall not require rating or closers. Corridor doors in smoke partitions shall not be equipped with closers but shall be equipped with positive latching. 407.4 The new facility has an occupancy load of less than 50 persons therefore an internal smoke barrier is not required. Note: The new facility shall be separated from the adjacent existing short stay unit by way of a fire wall. This, in affect, 5 shall act as a second means of egress for both the existing short stay and the new facility. 407.4.1 A refuge area in the new facility is needed for the twenty existing patients form the existing facility=20 x 30 sf/ea= 600 sf total. The combined areas of caf6, PT/OT and corridor exceed 600 sf. In a similar manner the existing facility could experience 47 clients (per new facility occupant load)x 6 sf/ea(due to non-bed confined)=282 sf. The existing corridor area+patient rooms exceeds this amount, OK. 407.5 There are no patient sleeping units with the new facility. 407.6 Automatic Fire Detection: Refer to fire alarm narrative and drawings per Shepherd Engineering Inc. 407.7 The facility is equipped with an existing secure yard on a lower floor accessed via the existing building. Chapter 5 503.1.3 It is intended that the new facility shall be a separate building. Therefore there will be two buildings on the same lot. Table 503 For type IB construction, l-2 use: 160' max. height, 4 story max, unlimited floor area. 504.1 Allowed tabular height= 160', actual= 17'-6"' +/- , OK. Number of stories allowed=4,provided= 1, OK. Increase in height and number of stories is not required. 506.2 Frontage increase not required. 506.3/ Table 506.4 Area modifications: not required as the actual new facility area of 2,825 sf is not bound due to an unlimited area parameter. 508.2.1 The misc. storage areas in the new facility total less than 10%of the floor area and will constitute a non-separated accessory use. Note: Waste and linen storage rooms are less than 100 sf. 6 Chapter 6 602.2 The intended type of construction for the new facility shall be IB. 603.1(1) It is intended to have fire retardant wood blocking in portions of the interior walls that are non-loadbearing and rated for less than 2 hours,non-bearing exterior walls that are non-rated and roof construction as permitted in Table 601. 603.1(2) Thermal and acoustical insulation shall have a flame spread index of 25 or less. 603.1(5,11) Combustible interior finish such as doors, door frames, blocking, window sashes and frames is allowed. The facility shall be designed to have a portion of some areas to have combustible wood trim and wainscot paneling. Table 601 For type IB construction: Structural frame: 1 hour reduced from 2 hour due to support of roof only(exception b) Bearing walls (interior and exterior): not applicable Non-bearing walls and partitions (exterior) Per input from ICC Tech. Dept. the requirements for the exterior non-loadbearing walls associated with the fire wall shall conform to section 705.4/705.5/705.6 and not Table 602. Non-bearing walls and partitions (interior) 0 hours Floor construction(including supporting beams and joists) 0 hours due to slab on grade Roof construction((including supporting beams and joists) 1 hour Table 602 Fire resistance rating required for exterior walls for use group I-2, type IB: Per input from ICC Tech. Dept. the requirements for exterior walls shall conform to section 705.4/705.5/705.6 for fire walls and not Table 602. Chapter 7 704.3 The new facility does constitute an additional building on the same lot and shall be regulated as a separate building. 704.5 For rated exterior walls with a separation distance greater than 5',the walls shall be rated for exposure to fire from the exterior. For rated exterior walls with a 7 separation distance less than 5',the walls shall be rated for exposure to fire from both sides. 704.6/ 704.11 The roof deck and supporting construction is non-combustible. Per exception(3) an exterior wall parapet is not required. 704.8 Openings within rated exterior walls: Refer to following analysis on fire walls. 705.2 The proposed fire wall shall offer a structural separation with the adjacent facility. 705.4 For type IB construction the I-2 use shall have a 3 hour fire resistance rating. 706.5 Horizontal continuity: Per exception 3 the fire wall shall terminate at the inside face of the exterior walls due to non-combustible wall construction and sprinkler protection. 705.5.1 A rating of 1 hour is required for 4' on either side of the new fire wall. The new construction shall be rated for 1 hour for this 4'. The existing m'Y maso veneer with cmu backup is assumed to be equal to 1 hour rated construction and extends the required 18"horizontally as required by 705.5. Therefore no additional remedial rated work is required with regards to the existing construction. 705.5.2 Per exception 2: Horizontal projecting elements with concealed spaces shall have the rated construction extend though and past the concealed spaces. 705.6 Vertical continuity: The existing roof is a ballasted system covering an EPDM system, rigid insulation above the concrete roof planks with an assumed classification at least of Class B. The roof of the new facility shall be of Class A construction and its roof components are non-combustible. There are no roof openings within 4'-0"of the new fire wall. Given the new facility's Class A roof and the existing concrete roof plank it appears that the migration of fire in a vertical manner is contained and satisfies the intent of exception 3. 705.6.1 The new facility shall have its fire wall extend vertically to the underside of the new non-combustible roof deck which is approximately 29" above the height of the lower existing roof. This is less than the minimum 30"required but the existing lower roof structure exceeds a 1 hour rating for 10' beyond due to its plank construction, OK. 8 705.8 Per Table 715.3 for a 3 hour fire wall: fire door assembly rating shall be rated for 3 hours. Opening width is not restricted due to sprinkler protection on each side of fire wall. 706.0 Fire Barriers: Required at 4'-0"lengths of horizontal run of the fire wall at the exterior walls. This portion of the wall,per 705.5 (1)/705.5.1, shall be rated for one (1)hour. 707.0 Shaft Enclosures:Not applicable. 708.0 Fire Partitions:Not applicable due to zero (0)rating. 708.3 Table 1016.1 Per Table 10 16.1 the corridors are not required to be rated for I-2 use with sprinklers. Per 407.3 the corridors shall act as smoke partitions. Per 710.3 smoke partitions are not required to be rated. 708.4 The facility shall have the corridor walls extend to the underside of the non- combustible deck. The corridor ceiling is non-rated due to 0 hour rating required in Table 1016.1. 709.1 Smoke Barriers: not applicable. 710.1/3 Smoke partitions: shall conform and be continuous to the underside of non- combustible deck. 710.5.3/ 407.3.1 Per 407.3.1 in non-rated smoke partition walls door openings are not required to be rated or equipped with closers. 711 Horizontal Assemblies: Applicable due to Table 601 for 1 hour rating of roof construction, including supporting beams and joist. 711.4 The rated assembly shall be created using spray on fire proofing materials. Skylights are allowed to be unprotected and penetrate through the rated deck as the structural integrity of the fire resistance rated roof construction shall be maintained via the spray on fire proofing material. 712 Penetrations: Penetrations through new rated construction shall conform to the requirements of this section. 9 715 Table 715.3 Fire door rating for 3 hour fire wall= 3 hour. Door rating for smoke partitions=0 hours 715.3.8 Fire doors, including 20 minute rated doors (if any), shall be self or automatic closing. Table 715.5.3 Wire glass is not allowed in the 3 hour rated fire doors. 719.2 Concealed thermal and sound insulation shall have a flame spread index of 25 or less and a smoke-developed index of not more than 450. Chapter 8 803.1 Class ratings: Class A: Flame spread 0-25, smoke developed 0-450 Class B: Flame spread 26-75, smoke developed 0-450 Class C: Flame spread 76-200, smoke developed 0-450 Table 803.5 For use group I-2 in a sprinklered facility: Vertical exits and exit passageways: Class B with exception(a, b) Corridors: Class B Rooms and enclosed spaces: Class B (exception h, i) Exception(a): Class C interior finish materials are permitted for wainscoting and paneling of not more than 1000 sf of applied surface in the grade lobby where applied directly to non-combustible base or over furring strips applied to a non- combustible base and fire blocked per 803.4.1 Exception h: Class C allowed in administrative areas. Exception is Class C allowed in areas with a capacity of 4 persons or less. 806.5 Combustible trim, exclusive of hand and guardrails, shall not exceed 10% of the aggregate wall or ceiling area in which it is located. This criteria shall apply to Dining/Activity area. Grade level lobby is restricted per Table 803.5 (exception a). Chapter 9 Refer to drawings and specifications Chapter 10 Means of Egress 1003.3.3 The corridors may have a 4"projection from the side when located 27"to 80" above the walking surface. 10 1003.3.4 Protruding objects shall not reduce the minimum clear width required in section 1104. 1004.1.1 The occupant load for the new facility shall be based upon Table 1004.1.2 B-Business use= 100 sf gross per person. Cafe assumed to be closest to Assembly, unconcentrated= 15 sf net per person. PT/OT space assumed to be closest to Exercise rooms= 50 sf gross per person. Total occupant load=47 persons. Refer to Code Plan for occupant load summary. Please note that the number of actual patients served is restricted to the twenty (20) short stay residents immediately adjacent to the new facility. 1005.1 Egress width= .2"per occupant for"other egress components" (ie: non-stairs). Total door width offered=(2 x 36"at door 102)+(3'-10" at door 132) = 118" total. Capacity= 164"/.2"per person= 590 occupants> actual occupant load of 47 persons, OK. [Note: Egress at door 132 is through a horizontal exit due to fire wall. There is no change in door width at door 132 (ie: original door width of 46" is matched by the new 46"wide door offered at door 132.] 1005.2 Door encroachment: Doors opening into the path of egress travel shall not reduce the required width to less than '/2 during the course of the swing. When fully open the door shall not project more than 7" into the required width. 1007.1 Two means of accessible egress are required,two are provided(vestibule 100 and horizontal exit inward at door 132). 1008.1.1 Size of doors: The I-2 portion of the facility shall offer 46"doors which allow for a 41.5" clear width when opened ninety degrees. The fire doors adjacent to the existing I-2 facility shall be sized at 46"wide to allow a 41.5"clear width when opened ninety degrees. Minimum door height=6'-8" (80"). 1008.1.2 Doors serving an occupancy of 50 persons or more shall swing in the direction of egress travel. Although the new facility's occupancy is less than 50 persons all egress doors shall swing in the direction of egress. 1008.1.3.2 Power activated egress doors shall conform to this section. 1008.1.4 Door landings at either side of the door shall be at the door elevation with a maximum slope of 2%. 11 1008.1.9 Due to the existing facility having an occupancy load greater than 50 persons the doors associated with doors 132 100 and 100a shall bee equipped with panic q devices. 1008.1.3.4 The new exterior egress doors may, at Owner's option, be equipped with access control that will meet the requirements of this section. 1010.1 Not applicable as the exterior sloped path of egress is pitched at 1:20 maximum. 1011.1 Exit signs shall be installed to meet the requirements of this section. 1012.0 Guards shall be installed at all exterior paths of travel that are located more than 30"above the grade below. 1012.2 The height of the guards shall be equal to 42". 1012.3 Opening limitations: Shall have balusters or ornamental patterns such that a 4" dia. sphere cannot pass through any opening up to a height of 34". From a height of 34"to 42" a sphere 8"in diameter may not pass. 1013.3 The maximum common path of travel distance allowed= 75 feet> 68'+/- provide, OK. 1015.1 Travel distance: Per Table 1015.1 for I-2 use, sprinklered=200' maximum> 47'+/-provided(from door 132 to door 100a). 1016.1 Per Table 10 16.1 for I-2 use with sprinkler: corridor rating required= 0 hour. Per 407.3 the corridors walls shall act as a smoke partition which is non-rated per 710.1/710.3. 1016.2 Due to use of the new corridor as a horizontal means of egress from the existing I-2 use a 96 corridor width(clear trim to trim) shall be maintained 1016.3 Dead end maximum allowed= 20', actual provided= 17'-6", OK. 1016.4.1 Note: The corridor ceiling shall be unrated due to the use of non-combustible ceiling and utilities above ceiling system and with rating of 1 hour satisfied by way of spray on fire proofing. 1018.1 The occupant load of the new facility is less than 500 persons and, per Table 1018.1 requires two exits. A total of two exits are provided via door 132 and doors 100a. 12 1020.2 Exit passageway width,per 1016.2 is 96". Per exception of 1003.3.3 each handrail may encroach upon this width not more than 4". 1021.1 Horizontal exits: Per 1018.0 two exits are required. One is provided directly to the exterior at door#100a(2 -36"wide doors). 1021.1 (exception 1) allows 2/3 of the total means of egress (ie: 2 x 2/3 = 1)to be a horizontal exit for an I-2 use. The other means of required egress is provided at door#132 which is a horizontal exit via a new fire wall. In a similar manner the existing 1-2 use also uses the new horizontal exit offered at door#132 to replace its original means of egress. Per 1021.1 (1)this existing I-2 use is allowed to have up to 2/3's of its required egress by way of a horizontal exit. 1021.2 A new 3-hour rated fire wall acts as the required separation. 1021.3 The openings within the fire walls shall be self closing or automatic closing when activated by smoke detectors per 907.10. 1021.4 Capacity of refuge: For I-2 use assume 30 sf/person. It appears that the existing corridor within the I-2 space is adequate for %2 the new facility load. In a similar manner the new facility's corridor appears to meet the size needed for the anticipated portion of the I-2 use. 1022.1 Exterior exit ramps and stairwells: As noted in 1010.1:Not applicable as the exterior sloped path of egress is pitched at 1:20 maximum and therefore does not qualify as a ramp. The exterior stair is offered for convenience as egress is by way of the sloped path at 1:20 pitch.
