Key findings

  1. Anchor bolt plan does not match PEMB manufacturer template

    Structural

    Critical

    Anchor bolt locations and sizes on foundation plan do not align with the pre-engineered building manufacturer's template.

  2. Pier and grade beam reinforcement conflict with embed plates

    Structural

    Critical

    Reinforcement in pier and grade beam details may conflict with embedded plates and anchor bolt assemblies.

  3. Missing grout space and leveling detail at column base

    Structural

    Critical

    Column base plate detail does not show grout space, leveling nuts, or grout type per AISC.

  4. Site grading does not direct water away from building

    Civil

    High

    Grading plan shows flat or negative slope toward building at one corner; surface water could pond at foundation.

  5. Foundation elevation vs. finish floor and slab

    Structural

    High

    Top of foundation elevation is not clearly coordinated with finish floor and slab-on-grade elevation.

  6. Geotechnical recommendation for allowable bearing not reflected

    Geotechnical

    High

    Geotechnical report specifies minimum footing size and bearing; foundation plan does not note compliance.

  7. Egress path from building to property line

    Architectural

    High

    Egress from building to public way may not meet width and slope requirements across site.

  8. Control joint and expansion joint layout for slab

    Structural

    Medium

    Slab-on-grade control joints and expansion joints not fully shown; PEMB column lines may need joints.

  9. Utility runs under or near footings

    Civil

    Medium

    Water or sewer runs are shown close to footings; clearance and protection not detailed.

  10. Wind and seismic category for anchorage

    Structural

    Medium

    Design basis (wind speed, seismic category) for foundation anchorage not stated on drawings.

Review details and suggested questions

Anchor bolt plan does not match PEMB manufacturer template

Structural

Critical

Summary: Anchor bolt locations and sizes on foundation plan do not align with the pre-engineered building manufacturer's template.

Why it matters: Mismatch will require field drilling or foundation revision and can delay steel erection.

Suggested next step: Coordinate foundation plan with approved PEMB anchor bolt template.

RFI draft: Please confirm anchor bolt plan matches the PEMB manufacturer's template.

Pier and grade beam reinforcement conflict with embed plates

Structural

Critical

Summary: Reinforcement in pier and grade beam details may conflict with embedded plates and anchor bolt assemblies.

Why it matters: Rebar conflicts can require redesign or field changes.

Suggested next step: Resolve rebar and embed conflicts in foundation details.

RFI draft: Please resolve reinforcement conflicts with embed plates in foundation details.

Missing grout space and leveling detail at column base

Structural

Critical

Summary: Column base plate detail does not show grout space, leveling nuts, or grout type per AISC.

Why it matters: Improper base condition affects load transfer and can cause settlement.

Suggested next step: Add base plate grout and leveling detail per standard practice.

RFI draft: Please add grout space and leveling detail at column base plates.

Site grading does not direct water away from building

Civil

High

Summary: Grading plan shows flat or negative slope toward building at one corner; surface water could pond at foundation.

Why it matters: Water against foundation can cause erosion and moisture issues.

Suggested next step: Revise grading to slope away from building minimum 2%.

RFI draft: Please revise site grading to slope away from building per code.

Foundation elevation vs. finish floor and slab

Structural

High

Summary: Top of foundation elevation is not clearly coordinated with finish floor and slab-on-grade elevation.

Why it matters: Elevation errors can affect slab thickness and door thresholds.

Suggested next step: Confirm and note all critical elevations on foundation and floor plans.

RFI draft: Please confirm foundation and finish floor elevations are coordinated.

Geotechnical recommendation for allowable bearing not reflected

Geotechnical

High

Summary: Geotechnical report specifies minimum footing size and bearing; foundation plan does not note compliance.

Why it matters: Non-compliance can cause settlement and liability.

Suggested next step: Verify footing sizes and add geotechnical compliance note.

RFI draft: Please confirm foundation design complies with geotechnical recommendations.

Egress path from building to property line

Architectural

High

Summary: Egress from building to public way may not meet width and slope requirements across site.

Why it matters: Life safety and permit approval depend on egress compliance.

Suggested next step: Verify egress path width and slope on civil and site plan.

RFI draft: Please verify egress path from building to property line per IBC.

Control joint and expansion joint layout for slab

Structural

Medium

Summary: Slab-on-grade control joints and expansion joints not fully shown; PEMB column lines may need joints.

Why it matters: Uncontrolled cracking and differential movement.

Suggested next step: Add control and expansion joint layout to slab plan.

RFI draft: Please add control and expansion joint layout for slab-on-grade.

Utility runs under or near footings

Civil

Medium

Summary: Water or sewer runs are shown close to footings; clearance and protection not detailed.

Why it matters: Settlement or damage to utilities if not properly detailed.

Suggested next step: Detail utility clearance and sleeving at foundations.

RFI draft: Please confirm utility clearance and protection at foundations.

Wind and seismic category for anchorage

Structural

Medium

Summary: Design basis (wind speed, seismic category) for foundation anchorage not stated on drawings.

Why it matters: Verification of design loads is needed for permit.

Suggested next step: Add design basis and load summary to structural notes.

RFI draft: Please add wind and seismic design basis to structural notes.

Drainage at building perimeter

Civil

Low

Summary: Perimeter drainage (strip drain or trench) at building edge not clearly specified.

Why it matters: Surface water at perimeter can affect foundations.

Suggested next step: Add perimeter drainage detail or note.

RFI draft: Please add perimeter drainage detail at building edge.

Vapor barrier and sub-slab preparation

Structural

Low

Summary: Vapor barrier and subgrade preparation for slab not fully specified.

Why it matters: Moisture and slab performance.

Suggested next step: Specify vapor barrier and subgrade prep in notes or spec.

RFI draft: Please specify vapor barrier and subgrade preparation for slab.
