Requirement: In sprinklered Group B, F and S occupancies, common path of egress travel may not exceed 100 ft.

Finding: The A.002 'FIRST FLOOR - COMMON PATH OF TRAVEL' table lists ROUTE D at 115'-0". Route D is drawn in the new warehouse addition (S-1), which is new construction. The Chapter 10 note on the same sheet states the sprinklered common-path limit is 100'. Exemption check: Table 1006.2.1 allows 100 ft for sprinklered B, F and S. No footnote or exception increases common path for S-1 or F-1, and the occupancy is not one with a longer sprinklered allowance. No exemption applies, so 115'-0" exceeds the 100'-0" limit by 15'-0".

Evidence: A.002

Requirement: In Massachusetts the fire code is 527 CMR 1.00 (NFPA 1 2021 with MA amendments), not the IFC, and code analyses must reference it, including for hazardous-materials and combustible-storage compliance.

Finding: The A.002 APPLICABLE CODES block lists 'FIRE CODE - 2021 INTERNATIONAL FIRE CODE NOT AMENDED'. The IFC is also used as the compliance basis elsewhere on the sheet. The Chapter 4 note '413: COMBUSTIBLE STORAGE SHALL COMPLY WITH THE INTERNATIONAL FIRE CODE' relies on it. The MAQ table footnote takes its 100% increase for cabinets and safety cans from 'SECTION 5003.9.10 OF THE INTERNATIONAL FIRE CODE'. Note 414.2.5.1 also references the IFC. The IFC is not adopted in Harlow. The hazardous-materials and storage basis must instead be shown under 527 CMR 1.00 (NFPA 1 2021 Chapter 60, with NFPA 30).

Evidence: A.002

Requirement: A panelboard must be protected by an overcurrent device rated no higher than its bus. When it is fed through a transformer with a 3-phase, 4-wire secondary, that device must be on the secondary side, because primary protection alone cannot protect the secondary conductors.

Finding: Panel PP6 on E.703 is 225 A MLO, 208Y/120 V, 3-phase, 4-wire, with 'Supply From: PLP3 VIA T5'. The Dry Type Transformer Copper Schedule on E.702 lists T5 (75 kVA) with a 208 V secondary overcurrent device of '250A-3P' and a secondary feeder of 4#250KCMIL & 1#4G - 2-1/2"C. Schedule note 4 places that device either in the panelboard main breaker or in an individually mounted breaker. PP6 has no main breaker, so the 250 A device would be the only protection for the 225 A bus. 250 A exceeds the 225 A bus rating. The New Work one-line on E.702 shows PLP3 → T5 → PP6 with no secondary breaker drawn at all. E.603 shows T5 and PP6 next to each other but no secondary device. Exemption check: the 240.4(F) exception for primary-only protection covers only single-phase 2-wire or 3-phase 3-wire delta-delta secondaries. T5 is 208Y/120 V, 3-phase, 4-wire, so no exception applies.

Evidence: E.702, E.703, E.603, E.111

Requirement: Work at 30% or more of the building's full and fair cash value brings the whole building under 521 CMR. Below 30%, work of $100,000 or more requires an accessible entrance, toilet room and drinking fountain.

Finding: A.002 lists 'ACCESSIBILITY CODE - 521 CMR (MAAB) AND 2010 ADA'. However, neither A.002 nor A.003 states the construction cost against the building's full and fair cash value. The scope combines a Level 2 alteration with a 19,550 SF addition, so the 30% threshold is plausibly exceeded. That would extend 521 CMR compliance to the existing building outside the 2,814 SF work area.

Evidence: A.002, A.003

Requirement: Quantities per control area must be within the MAQ for the actual condition (storage, closed use, open use). For example, sprinklered combined IB/IC is 240 gal storage/closed use but only 60 gal open use.

Finding: The MAQ analysis does not establish the use condition or the quantities in the new building: - On A.003, every row of the CURRENT HAZARDOUS MATERIALS table shows the storage method as 'CLIENT TO CONFIRM'. - The A.002 'MAQ STORAGE PER CONTROL AREA' chart compares quantities only against the storage column. - In the F-1 production use, open-use limits may govern. Control Room 2 shows IB/IC at 59.4 gal against a 60-gal open-use limit. - All four control areas in the new addition are listed as '_' (unknown), with the note 'OWNER TO MAINTAIN MAXIMUM ALLOWED QUANTITIES'. - The table footnote relies on the cabinet/safety-can increase, but the storage method is unconfirmed.

Evidence: A.002, A.003

Requirement: Exterior steel or wooden egress stairs must be examined and certified for structural adequacy every five years by a registered design professional or other qualified person.

Finding: A.501 shows a new exterior egress stair and landing at Door 111A. It is built of 'GALV BAR GRATING STAIR TREADS & LANDING' and 'GALV METAL GUARDRAIL & HANDRAIL', which makes it a steel exterior stairway subject to the Massachusetts five-year recertification. Neither A.501 nor the stair details note this requirement for the owner.

Evidence: A.501, A.213, A.201, A.211, A.212

Requirement: A fire door in a fire wall must be a labeled assembly of the required size and must be self-closing or automatic-closing. Openings in a fire wall are limited to 156 sq ft each unless both sides are sprinklered, and to 25% of the wall length in aggregate.

Finding: The A.631 Door Schedule lists overhead doors 111D and 111E as type OHD1, 3HR, with width and height both entered as 0" x 0". No hardware set, frame or operator is given for either door. A note at the bottom of the schedule shows "144" 144"" (12'-0" x 12'-0", 144 sq ft), but it is not tied to a door number. At 144 sq ft each opening is within the 156 sq ft limit. However, the schedule does not show (a) the actual door size, (b) that the doors are listed 3-hour rolling fire doors, or (c) the automatic-closing means: a fire alarm or smoke detector release and governor, as required for a fire door normally held open in a fire wall. The aggregate opening width in the FS3 wall (111C at 3 ft, plus 111D and 111E at 12 ft each, about 27 ft total) cannot be checked against 25% of the wall length on this sheet.

Evidence: A.631, A.621, A.402, A.002, ASR.101, A.101, ASR.201, A.113, FA.101, A.312

Requirement: Zone controls that run both heating and cooling must be able to hold a deadband of at least 5°F, with no heating or cooling energy used inside that band.

Finding: Detail 4/H.903, Air Control Terminal with Electric Heater, shows the terminal box damper setpoint chart. It defines a '2°F DEAD BAND' from -1°F to +1°F about setpoint, with the electric coil energized below -1°F and a '3°F COOLING RANGE' above. This sequence applies to VAV-01, VAV-02 and VAV-03 on H.600, Detail 3. Each box has integral electric reheat and is cooled by the same packaged RTU through a single zone sensor. The C403.4.1.2 exceptions do not apply: there is no manual changeover thermostat and the zones are not special-occupancy zones. A 2°F band is below the 5°F minimum.

Evidence: H.903, H.600

Requirement: Toilet rooms, kitchens and other exhausted spaces must be mechanically exhausted at not less than the rates in the MA-amended exhaust column of IMC Table 403.3.1.1.

Finding: H.700 contains no exhaust fan schedule. EF-112 is tagged in the electrical schedules (PLP3 CKT 26,28,30; 3 FLA, 4 MCA, 15 MOCP) but has no CFM, ESP or served spaces in the HVAC set. ERC-2 is scheduled at 2,400 CFM on 'EXHAUST' service with no exhaust source identified. The new/renovated toilet rooms 103, 104, 105, 106 and Unisex 109 (A.611) and Kitchen Area 107A have no scheduled exhaust quantities. The required-versus-scheduled exhaust comparison therefore cannot be made. Existing EF-2E is shown to remain on HD.101 with no capacity stated.

Evidence: H.700, H.000, E.703, A.611

Requirement: The fan serving toilet room exhaust must deliver the scheduled grille total so that each toilet room meets its minimum exhaust rate.

Finding: H.600, Detail 3 connects the renovated restrooms 103–106 to '(E)12"x10" EXH UP TO (E) EF-2E'. The restroom grilles are 'EG-A 140 TYP. 2' (6"x6" and 8"x8"), about 280 CFM per room. No existing fan capacity or field test value for EF-2E is shown. It cannot be confirmed that the existing fan can deliver the new grille total.

Evidence: H.600, H.700

Requirement: Every circuit and circuit modification must be legibly identified by its specific purpose or use, clearly enough to tell it apart from all others.

Finding: The new panel PP6 on E.703 labels CKT 13, 15, 17 and 18 only as 'Receptacles', with no room or area. E.603 shows these circuits in New Control Rooms #1–#3 (112–114) and the XP receptacles there. PP6 also has three identical 'ROLL-UP DOOR' entries (CKT 1-3-5, 7-9-11, 12-14-16) with no door number. On E.702, both MDP schedules list CKT 3 and CKT 6 as 'EXISTING LOAD (ON - UNLABELED)' in a switchboard being modified under this permit.

Evidence: E.703, E.603, E.702

Requirement: Switchboards and panelboards likely to be serviced while energized must carry arc-flash warning labels. Service equipment rated 1200 A or more needs the additional 110.16(B) label data. Breakers with trip settings of 1200 A or more must have an arc energy reduction method.

Finding: None of the following contains an arc-flash labeling requirement for the new PLP3, PP6 or T5, or for the 2000 A add-alternate MDP: the General Notes on E.001, the Typical Panelboard Notes on E.701–E.703, or the labeling details on E.900, which cover only receptacle, switch and disconnect circuit labels. E.001 lists the abbreviation 'AFR – ARC FAULT REDUCTION', but no breaker on the one-line is assigned it. The service/main device rating for the 2000 A MDP is not shown, so it cannot be determined whether 240.87 applies.

Evidence: E.702, E.001, E.900

Requirement: Equipment interrupting and short-circuit ratings must equal or exceed the available fault current at the line terminals. Non-dwelling service equipment must be field-marked with the available fault current and the date of the calculation.

Finding: Ratings shown: MDP 50KAIC, new PLP3 42KAIC, new PP6 10KAIC. Existing PLP1, PLP2, PP1-A, PP1C, PP2 and PP5 are 'ETR'. No utility available fault current, transformer impedance or short-circuit study appears anywhere on the electrical sheets. Typical Panelboard Note 5 prohibits series ratings, so PLP3 (42 kA) must be fully rated for the fault current at its terminals downstream of a 50 kA-rated MDP. E.603 keynote 2 requires the new 250 A MDP breaker to match the existing kAIC, but that value is not stated. (Applies across 5 sheets: E.702, E.703, E.603, E.602, E.111.)

Evidence: E.702, E.703, E.603, E.602, E.111

Requirement: A plumbed emergency shower head must be at least 82 in. and no more than 96 in. above the floor.

Finding: Detail 10 'EMERGENCY SHOWEER EYEWASH' on P.900 dimensions the drench shower head as '80" MIN' above the finished floor. This allows a head as low as 80 in., which is below the 82 in. minimum. No exception applies. ESEW-1 is scheduled on P.700 as Guardian G1902; the product's head height is not stated, and the detail dimension governs installation.

Evidence: P.900, P.700

Requirement: Each safety shower must deliver 20 gpm continuously for 15 minutes at 60–100 °F. The supply must be sized for two showers operating together, and a combination unit must also supply its eyewash at the same time.

Finding: P.700 Thermostatic Mixing Valve Schedule lists TMV-2 (Powers ETV200, ASSE 1071) with a design flow of 20.0 GPM at a 10.0 psi maximum pressure drop and a 1" outlet. The demand it serves is higher: - ESEW-1 is a combination shower/eyewash (Guardian G1902). The shower alone is scheduled at 20.0 GPM, before any eyewash flow is added. - 248 CMR 10.10(13) requires the supply to be sized for two showers running together, which is 40 gpm. The 20.0 GPM valve design flow therefore falls short of the required demand. The 1" outlet also feeds the 1-1/4" tempered supply shown in P.900 Detail 10. Exemption check: 248 CMR 10.10(13) as amended contains no reduced-flow exception for combination units.

Evidence: P.700, P.900, P.600, E.703

Requirement: A fixed storage water heater branch circuit must be rated at no less than 125% of the heater's nameplate current.

Finding: P.700 schedules EWH-1 at 12,200 W, 208 V, single phase. The electrical schedules list EWH-1 at 12KW on a 50 A 3P breaker (PP2 CKT 21,23,25). - If single phase as scheduled on P.700: 12,200 W / 208 V is about 58.7 A, which requires about 73 A at 125%. The 50 A breaker is undersized. - If three phase: the current is about 34 A, which requires about 42 A at 125%, and the 50 A breaker is adequate. The phase must be resolved.

Evidence: P.700, E.703

Requirement: Minimum plumbing facilities are determined from the 248 CMR fixture table using the code-calculated occupant load; a reduction based on actual staffing needs relief from the Board of State Examiners of Plumbers and Gas Fitters.

Finding: The A.002 PLUMBING FIXTURE REQUIREMENTS table computes required fixtures from occupant loads of 78/78, 34/34 and 18/18. The REQUIRED row shows toilets F=7/M=5, lavatories F=8/M=8, drinking fountains 4 and mop sinks 3. The PROVIDED row shows toilets F=6/M=3 plus 1 unisex and 2 urinals, lavatories F=4/M=4 plus 1 unisex, 1 drinking fountain and 1 mop sink. The note '* PLUMBING FIXTURES PROVIDED BASED ON ACTUAL OCCUPANT LOAD OF 45 AT PEAK OPERATION' justifies the shortfall. No variance from the Plumbing Board is cited.

Evidence: A.002, A.611, P.700, A.003, P.600, P.601

Requirement: Fire department access roads must be at least 20 ft wide, with turning radii acceptable to the AHJ and at least 13 ft 6 in. vertical clearance. The road must come within 150 ft of all portions of the exterior walls of the first story.

Finding: The C2.1 Zoning Summary lists 'Driveways and Entrances … 20' (two way)' and proposed 'Existing Driveway'. This is the only access dimension on the sheet. The 19,550 SF warehouse addition enlarges the building footprint, so the 150 ft perimeter coverage must be rechecked for the new faces. C2.1 gives no fire lane width at the addition, no inside or outside turning radius, and no hose-lay measurement. These values belong on the C5.1 Layout & Materials Plan, which is not part of this page. (Applies across 7 sheets: C2.1, C5.1, C6.1, FP.101, FP.600, L.100, L.101.)

Evidence: C2.1, C5.1, C6.1, FP.101, FP.600, L.100, L.101, L.300, L.200

Requirement: Each room must be assigned a hazard classification or commodity basis, and the hydraulic remote area must cover the most demanding hazard served.

Finding: The new Control Rooms #1–#3 (112–114) are enclosed with 45-minute doors per the A.631 schedule. They sit under the low roof shown on FP.601 ('LOW ROOF AREA. COORDINATE PIPING AND SPRINKLERS AS REQUIRED'). They also receive in-duct sprinklers for exhaust ducts 10 in. or larger, per detail 9/FP.901. FP.601 does not give a hazard classification, density/area or sprinkler type for the control rooms. Both calculated remote areas are ESFR areas in the open warehouse. The in-duct sprinkler demand is not included in either summary ('Total Additional Flow: 0 GPM').

Evidence: FP.601, FP.901, A.113, A.631

Requirement: A lot of 51–75 spaces needs at least 3 accessible spaces under both 521 CMR 23.2.1 and ADA 208.2. At least 1 of those must be van-accessible: 1 in 8 under 521 CMR 23.2.2 and 1 in 6 under ADA 208.2.4, and the stricter rule governs.

Finding: The 'Parking Computations' table on C2.1 lists Business Office 6,600 SF at 1 per 300 GFA, Lab 6,000 SF at 1 per 400 GFA and Warehouse 31,700 SF at 1 per 1,500 GFA. It gives a total of 57 required and 57 provided. Under 521 CMR 23.2.1 (51–75 range) and ADA 208.2, that total requires 3 accessible spaces, including 1 van-accessible space. C2.1 does not state how many accessible or van-accessible spaces are provided, so the count cannot be compared with the 57-space total on this sheet. The legend lists accessible-space symbology, but no accessible count appears in the parking table. (Applies across 4 sheets: C2.1, C5.1, L.101, L.100.)

Evidence: C2.1, C5.1, L.101, L.100, C7.1, L.200, L.300, L.603, L.606, L.301, L.400

Requirement: Accessible walking surfaces must have a running slope of 5% or less and a cross slope of 2% or less. Accessible parking spaces and access aisles must slope no more than 2% in any direction.

Finding: The C2.1 Regulatory Notes say accessible parking and pedestrian routes must meet the more stringent of the ADA and 521 CMR. However, C2.1 gives no numeric running-slope or cross-slope values for walks, ramps or accessible parking. The slope comparison therefore cannot be made from this sheet. The spot grades and slope labels at the accessible spaces and the entrance walk are carried on C6.1 and L.200, with walk and curb-ramp details on C7.x.

Evidence: C2.1, C6.1, L.200, C7.1, C5.1, L.101, C7.2, L.603, L.604, L.606, L.601, L.301, L.400
