Automotive Facility: 258 Issues Found

Summary: Drawings show normal and emergency power terminating at the same lighting fixture/circuit without proper separation or switching. Emergency circuits must be isolated per NEC and IBC.

Why it matters: Life safety and egress lighting depend on emergency power. Shared termination can cause both to fail in an outage and may fail plan review.

Suggested next step: Separate normal and emergency lighting circuits and verify emergency lighting layout per code.

RFI draft: Please clarify normal vs emergency power termination and revise lighting plans per NEC and IBC.

Summary: Emergency lighting interface is shown on the same control link as normal lighting. Emergency lighting must be on a dedicated circuit and control path.

Why it matters: Failure to isolate emergency lighting control can compromise life safety during power loss.

Suggested next step: Provide dedicated control and circuit for emergency lighting per IBC and NFPA 101.

RFI draft: Please separate emergency lighting control from normal lighting and confirm code compliance.

Summary: Loading dock and door power are indicated as 208V including single-phase door motors. Equipment schedules or specs may require different voltage; single-phase vs three-phase must match.

Why it matters: Voltage and phase mismatch can damage equipment and cause permit comments.

Suggested next step: Verify door motor and dock equipment voltage/phase and align electrical design.

RFI draft: Please confirm loading dock and door motor voltage and phase; revise power distribution if needed.

Summary: Ramp railing detail labeled as GUARD shows 3'-0" height. IBC requires guard height of 42" minimum. Ramp guard shown at 3'-0" is non-compliant.

Why it matters: Guard height below 42" is a life safety and fall hazard violation; will be flagged at plan check.

Suggested next step: Revise guard/railing detail to minimum 42" height and update all ramp guard callouts.

RFI draft: Please correct ramp guard height to 42" minimum per IBC and revise details.

Summary: Unit heaters are scheduled as hot-water Sterling units on mechanical drawings; specification specifies different manufacturer or type.

Why it matters: Schedule/spec conflict affects procurement, coordination, and may delay permit.

Suggested next step: Align unit heater schedule with specification or issue addendum to match.

RFI draft: Please confirm unit heater manufacturer and type; align schedule and spec.

Summary: VRF equipment on schedule is shown as HITACHI; specification allows only Mitsubishi or other specified manufacturer.

Why it matters: Approved manufacturer mismatch can cause rejection and rework.

Suggested next step: Revise VRF schedule to specified manufacturer or update spec to allow HITACHI.

RFI draft: Please align VRF equipment schedule with specification (manufacturer).

Summary: Stair flights show riser heights exceeding the 7-inch maximum permitted by IBC. Calculated or dimensioned risers exceed code.

Why it matters: Riser height over 7" is a code violation and trip hazard; plan check will require correction.

Suggested next step: Recalculate stair rise/run and revise stair layout to meet 7" max riser and 11" min run.

RFI draft: Please revise stair geometry to meet IBC riser and run requirements.

Summary: Roof details and drawing callouts specify EPDM membrane; roofing specification specifies TPO. Membrane type must match for warranty and design.

Why it matters: EPDM vs TPO affects attachment, flashing, and warranty; conflict will be caught at review.

Suggested next step: Confirm roofing membrane type (EPDM or TPO) and align details and specification.

RFI draft: Please align roof membrane type between details and specification.

Summary: Concrete notes specify normal-weight 3,500 psi for slab-on-deck. Other notes or details may specify different strength or lightweight concrete.

Why it matters: Concrete strength and weight affect structural design and loading; must be consistent.

Suggested next step: Confirm slab-on-deck concrete specification and align all notes and details.

RFI draft: Please confirm slab-on-deck concrete specification and align structural notes.

Summary: Structural point-load table for P1 shows 525 lbs; RTU weights or equipment schedule shows different weight for the same location.

Why it matters: Point load mismatch can under-design roof structure and cause structural review comments.

Suggested next step: Reconcile RTU/equipment weights with structural point-load table and revise as needed.

RFI draft: Please align RTU/equipment weights with structural point-load table.

Summary: Stair section (South Mezzanine) shows rise and riser counts that exceed code maximum or do not match plan dimensions.

Why it matters: Stair geometry must comply with IBC; inconsistent section vs plan can delay permit.

Suggested next step: Verify stair rise/run and riser count; revise section and plan for consistency and code compliance.

RFI draft: Please align stair section with plan and confirm IBC compliance.

Summary: Drawings specify anchor bolt/rod grade as ASTM F1554 Grade 105; specification or structural notes may specify different grade.

Why it matters: Anchor grade affects capacity and special inspection; must match across documents.

Suggested next step: Confirm anchor bolt/rod grade and align drawings and specification.

RFI draft: Please confirm anchor bolt grade and align structural drawings with spec.

Summary: Design criteria or general notes conflict regarding ASD vs LRFD for roof joist framing. Drawings and calcs must use a single design method.

Why it matters: Mixed design methodology can invalidate structural design and cause rejection.

Suggested next step: Confirm design method (ASD or LRFD) and align general notes and structural design.

RFI draft: Please confirm structural design method and align design criteria.

Summary: Special inspections sheet does not include structural steel connections that are required by IBC and AISC for the scope shown.

Why it matters: Missing special inspection items can cause permit hold and field issues.

Suggested next step: Add structural steel connection inspection to special inspections list per IBC.

RFI draft: Please add structural steel connection special inspections per IBC.

Summary: Roof weatherproof notification appliance shown as 110cd conflicts with specification maximum candela for strobes.

Why it matters: Exceeding spec can affect listing and approval; under-powering can affect coverage.

Suggested next step: Align notification appliance candela with specification and verify coverage.

RFI draft: Please confirm notification appliance candela and align with spec.
