Food Processing / Cold Chain: 114 Issues Found

Summary: The architectural upper roof sheet's symbol legend specifies the standing seam roof panels as '22 GA OR APPROVED EQUAL.' The structural upper roof framing keynotes specify '26 GA. GALV. STANDING SEAM METAL ROOFING - SEE ROOF PLAN FOR SPECIFICATION.' The structural cross-reference therefore does not match the roof plan gauge.

Why it matters: Different panel gauges affect procurement, submittals, and roof assembly compliance. Without one governing gauge, the roofing package can be priced or installed incorrectly.

Suggested next step: Clarify the required gauge for the standing seam metal roof and revise the architectural and structural roof legends/keynotes so one consistent gauge governs.

RFI draft: Clarify the required gauge for the standing seam metal roof and revise the architectural and structural roof legends/keynotes so one consistent gauge governs.

Summary: The sheet's sanitary facilities note allows 'A CLEAR SPACE FIFTY-SIX (56) INCHES BY SIXTY-THREE (63) INCHES IN SIZE' as an alternative toilet-room turning space. CBC 11B-304.3 only permits turning space as either a 60-inch-diameter circle or a T-shaped space within a 60-inch square minimum. Because the note permits a 56-inch dimension, it...

Why it matters: If restroom layouts are developed from this note, accessible toilet rooms can be undersized and fail accessibility review or field inspection. Correcting this after layout, framing, and fixture rough-in would cause redesign and rework.

Suggested next step: Revise SANITARY FACILITIES note 6a to remove the 56-inch by 63-inch alternative and require turning space to comply with CBC 11B-304.3.1 or 11B-304.3.2. Confirm that all toilet room layouts are based on the corrected turning-space requirement.

RFI draft: Revise SANITARY FACILITIES note 6a to remove the 56-inch by 63-inch alternative and require turning space to comply with CBC 11B-304.3.1 or 11B-304.3.2. Confirm that all toilet room layouts are based on the corrected turning-space requirement.

Summary: The sanitary facilities note for water closet compartments states that a 'CLEAR FLOOR SPACE OF 30 INCHES BY 48 INCHES MINIMUM IN FRONT OF THE WATER CLOSET' is acceptable, with a '30-INCH BY 48-INCH MANEUVERING SPACE PROVIDED OUTSIDE.' CBC 11B-604.3.1 requires 60 inches minimum measured from the side wall, 56 inches minimum measured from the...

Why it matters: If this note is used for design or construction, accessible toilet compartments could be built too small to pass accessibility review and inspection, requiring redesign and field rework of toilet room layouts.

Suggested next step: Please revise the water closet compartment note to match CBC 11B-604.3.1 and confirm the project’s accessible compartments will provide 60 inches minimum from the side wall, 56 inches minimum from the rear wall, and a 60-inch by 48-inch maneuvering space in front of the water closet.

RFI draft: Please revise the water closet compartment note to match CBC 11B-604.3.1 and confirm the project’s accessible compartments will provide 60 inches minimum from the side wall, 56 inches minimum from the rear wall, and a 60-inch by 48-inch maneuvering space in front of the water closet.

Summary: The single-accommodation sanitary facilities note allows a water closet space with only a 'THIRTY-TWO (32) INCH WIDE CLEAR SPACE FORM A WALL AT ONE SIDE OR TWENTY-EIGHT (28)\' INCH TO ADJOINING FIXTURE' and 'FOURTY-EIGHT (48)\' INCHES OF CLEAR SPACE IN FRONT OF THE WATER CLOSET.' CBC 11B-604.3.1 requires 60 inches minimum measured from the side...

Why it matters: If followed, this note can place the water closet and adjoining fixture too close together and force redesign or reconstruction of the accessible restroom during plan review or inspection.

Suggested next step: Please revise the single-accommodation sanitary facility water closet clearance note to match CBC 11B-604.3.1 and confirm the accessible room layouts are based on 60 inches minimum from the side wall, 56 inches minimum from the rear wall, and a 60-inch by 48-inch maneuvering space in front of the water closet.

RFI draft: Please revise the single-accommodation sanitary facility water closet clearance note to match CBC 11B-604.3.1 and confirm the accessible room layouts are based on 60 inches minimum from the side wall, 56 inches minimum from the rear wall, and a 60-inch by 48-inch maneuvering space in front of...

Summary: Detail 7 states that tactile exit signs are required only at 'EXIT DOORS LEADING TO ENCLOSED EXIT STAIRWAYS' and 'EXIT DOORS LEADING TO OUTSIDE.' CBC 11B-216.4.1 also requires these Chapter 10 exit-door signs at doors to exit passageways. The sheet therefore omits one CBC-required location for the tactile exit door signage.

Why it matters: If this note is used for placement and procurement, required signs at exit passageway doors can be missed. That can trigger plan review comments or final inspection corrections and require added signage and rework before approval.

Suggested next step: Revise Detail 7 so the required locations match CBC 11B-216.4.1, including doors to exit passageways, and confirm all project locations that require the tactile exit door signs.

RFI draft: Revise Detail 7 so the required locations match CBC 11B-216.4.1, including doors to exit passageways, and confirm all project locations that require the tactile exit door signs.

Summary: The ramp landing detail for '(B) CHANGE IN DIRECTION' shows a landing dimensioned '60\' MIN.' by '60\' MIN.'. CBC 11B-405.7.4 requires a landing at a ramp direction change to be 60 inches minimum by 72 inches minimum in the direction of downward travel from the upper ramp run. The detail is therefore short in one direction.

Why it matters: If built per this standard detail, a direction-changing ramp landing would not meet accessibility requirements and could require redesign or reconstruction after plan review or field inspection.

Suggested next step: Revise the 'CHANGE IN DIRECTION' ramp landing detail so the landing is 60 inches minimum by 72 inches minimum in the direction of downward travel, and verify that any related standard details use the corrected geometry.

RFI draft: Revise the 'CHANGE IN DIRECTION' ramp landing detail so the landing is 60 inches minimum by 72 inches minimum in the direction of downward travel, and verify that any related standard details use the corrected geometry.

Summary: In the 'STRAIGHT RAMP RUN' detail, the leftmost `60' MIN.` dimension segment aligns with the `BOTTOM LEVEL PLATFORM`, so the bottom landing is shown as 60 inches minimum in the direction of ramp travel. CBC 11B-405.7.3.1 requires bottom landings to extend 72 inches (1829 mm) minimum in the direction of ramp run.

Why it matters: The visual issue is specifically the bottom landing callout. That 60-inch bottom-platform dimension conflicts with the California code minimum and should be revised so the detail clearly documents a 72-inch minimum bottom landing.

Suggested next step: Please revise the straight-ramp standard detail so the bottom level platform is clearly shown as 72 inches minimum in the direction of ramp run for the California condition.

RFI draft: Please revise the straight-ramp standard detail so the bottom level platform is clearly shown as 72 inches minimum in the direction of ramp run for the California condition.

Summary: The ADA access note states that the route from the public sidewalk to the building entry is a '36\' MINIMUM WIDTH ACCESSIBLE PATH.' CBC requires at least one accessible route from public streets and sidewalks to the accessible entrance, and the clear width for sidewalks and walks on that route is 48 inches minimum unless an enforcing-agency...

Why it matters: If this note is used for layout, the sidewalk-to-entry accessible route would be undersized and could be rejected during accessibility review or field inspection, requiring redesign and replacement of site flatwork.

Suggested next step: Revise the ADA access note and any related site-walk dimensions so the route from the public sidewalk to the building entry is 48 inches minimum, or provide the enforcing-agency hardship determination that permits a 36-inch width.

RFI draft: Revise the ADA access note and any related site-walk dimensions so the route from the public sidewalk to the building entry is 48 inches minimum, or provide the enforcing-agency hardship determination that permits a 36-inch width.

Summary: The civil general note states that ADA ramp transitions are to have '5'-0\' LANDINGS.' CBC 11B-405.7.3.1 requires bottom ramp landings to extend 72 inches minimum in the direction of ramp run. A 5'-0\' landing is only 60 inches, so the note under-sizes bottom ramp landings by 12 inches.

Why it matters: If this note is used for site ramp layout, accessible route ramps can be built with noncompliant bottom landings and would require redesign or concrete rework to pass accessibility review.

Suggested next step: Revise the ADA site note and any related ramp details to distinguish top and bottom landings, and confirm that all bottom ramp landings will be 72 inches minimum in the direction of ramp run.

RFI draft: Revise the ADA site note and any related ramp details to distinguish top and bottom landings, and confirm that all bottom ramp landings will be 72 inches minimum in the direction of ramp run.

Summary: The parking analysis states that the site provides 29 spaces including 2 ADA stalls. The site plan shows the accessible stalls as EV-marked stalls with wheelchair symbols. CBC 11B-208.1 states that electric vehicle charging stations are not parking spaces, and Table 11B-208.2 requires 2 accessible parking spaces for a facility with 26 to 50...

Why it matters: If left unchanged, the accessible parking count is being satisfied by spaces identified as EV charging stations. This is a likely plan-check correction and can require restriping, sign revisions, and parking/EV layout changes before approval or during construction.

Suggested next step: Revise the site plan and parking analysis to provide 2 accessible parking spaces that are not identified as EV charging stations, or submit a code-based justification acceptable to the AHJ showing why the EV-marked ADA stalls satisfy Section 11B-208.

RFI draft: Revise the site plan and parking analysis to provide 2 accessible parking spaces that are not identified as EV charging stations, or submit a code-based justification acceptable to the AHJ showing why the EV-marked ADA stalls satisfy Section 11B-208.

Summary: The trench repair detail allows “CLEAN SAND OR 1500 PSI LEAN CONC MIX.” CBC Section 1904.2 states “Nonstructural concrete shall have a minimum specified compressive strength, f´c, of 2,500 psi (17.2 MPa) for Class F0; 3,000 psi (20.7 MPa) for Class F1; and 3,500 psi (24.1 MPa) for Classes F2 and F3.” The 1,500 psi concrete option is therefore...

Why it matters: If this remains on the drawings, plan review or field inspection can require revision of the detail or replacement of installed low-strength concrete, creating avoidable rework and delay.

Suggested next step: Please revise Detail 6 to remove the “1500 PSI LEAN CONC MIX” option or replace it with a code-compliant concrete strength, and confirm the intended trench backfill material for both trench-width conditions.

RFI draft: Please revise Detail 6 to remove the “1500 PSI LEAN CONC MIX” option or replace it with a code-compliant concrete strength, and confirm the intended trench backfill material for both trench-width conditions.

Summary: The protruding-object standard on this sheet states: 'FREESTANDING OBJECT MOUNTED ON POSTS OR PYLON MAY OVERHANG 12\' MAX FROM 27\' TO 80\' ABOVE FINISH FLOOR' at an 'ACCESSIBLE ROUTE.' Section 1003.3.2 limits a free-standing object mounted on a post or pylon to not more than 4 inches of overhang in that height range. The detail therefore...

Why it matters: If this standard is used for signs or similar obstructions, the installed work would violate the protruding-object requirement on the path of travel and could require relocation or replacement during plan review or field inspection.

Suggested next step: Please revise the protruding-object detail so post- or pylon-mounted objects with leading edges more than 27 inches and less than 80 inches above the finished floor do not overhang more than 4 inches, and reissue the sheet with the corrected standard.

RFI draft: Please revise the protruding-object detail so post- or pylon-mounted objects with leading edges more than 27 inches and less than 80 inches above the finished floor do not overhang more than 4 inches, and reissue the sheet with the corrected standard.

Summary: The anchorage note on sheet M100 expressly requires secure anchorage for floor- or roof-mounted mechanical equipment weighing more than 400 lbs and for wall- or ceiling-suspended equipment weighing more than 20 lbs, while also citing CMC 303.4. The same sheet's general notes reference roof openings for HVAC equipment and exhaust fans, and the...

Why it matters: The note does not explicitly state that lighter fixed equipment is exempt, but its threshold-based wording can reasonably be read that way and does not match the broader CMC 303.4 requirement cited in the note. Because the sheet also includes exhaust-fan-related content, this mismatch is relevant to equipment shown on the sheet and could lead...

Suggested next step: Please revise the anchorage note so it does not imply that secure fastening applies only above the listed weight thresholds. If the intent is to address seismic anchorage thresholds under CBC/ASCE separately from CMC 303.4 fastening requirements, please clarify that distinction and identify the required attachment/anchorage basis for EF-1 and...

RFI draft: Please revise the anchorage note so it does not imply that secure fastening applies only above the listed weight thresholds. If the intent is to address seismic anchorage thresholds under CBC/ASCE separately from CMC 303.4 fastening requirements, please clarify that distinction and identify the...

Summary: The mechanical note allows outside air/intake air openings to be located 'A MINIMUM OF 10'-0\'' from exhaust fans and gas flue vents. CMC 407.2.1 requires outdoor air intakes to be located at least 25 feet from exhaust outlets of ventilating systems and combustion equipment stacks. The note therefore permits intake locations 15 feet closer than...

Why it matters: If this note is used for layout and installation, outdoor-air intakes can be placed too close to exhaust and flue discharges. That is a direct code conflict and can trigger plan review comments, relocation of roof penetrations, and field rework.

Suggested next step: Revise the intake-location note to require a minimum 25-foot separation between outdoor air intakes and exhaust fans / gas flue vents, and confirm all related intake and exhaust locations are updated to match CMC 407.2.1.

RFI draft: Revise the intake-location note to require a minimum 25-foot separation between outdoor air intakes and exhaust fans / gas flue vents, and confirm all related intake and exhaust locations are updated to match CMC 407.2.1.

Summary: The sheet's mechanical general note permits flexible ductwork up to 6'-0'. CMC 603.4.1 limits flexible air ducts to not more than 5 feet in length. The note therefore authorizes a flexible duct length that exceeds the code maximum by 1 foot.

Why it matters: Because this is a general installation note, contractors could apply the 6'-0' limit throughout the project. If installed per the note, the work would be noncompliant and could require field correction or replacement during inspection, creating avoidable ceiling and duct rework.

Suggested next step: Revise General Note 4 to limit flexible air ducts to 5 feet maximum in accordance with CMC 603.4.1, and confirm that any intended runouts over 5 feet will be changed to hard duct or otherwise redesigned compliantly.

RFI draft: Revise General Note 4 to limit flexible air ducts to 5 feet maximum in accordance with CMC 603.4.1, and confirm that any intended runouts over 5 feet will be changed to hard duct or otherwise redesigned compliantly.
