MEP penetration structural coordination

Why does penetration analysis matter?

An unauthorized hole through a beam or slab is cheap to move on paper and extremely expensive after the concrete is poured.

How does Helonic go from PDF upload to a penetration conflict report?

Helonic cross-references MEP routing against structure for every floor of your set.

1. Identify structure. Our AI reads the structural plans to map every beam, column, shear wall, and load-bearing element with their sizes and locations.
2. Map MEP routing. Mechanical ductwork, plumbing risers, electrical conduit, and fire protection piping are traced from the MEP sheets to build a complete routing picture.
3. Cross-reference. Every MEP element is checked against the structural grid. The system identifies where pipes, ducts, or conduit pass through beams, columns, or shear walls.
4. Flag conflicts. Each penetration is evaluated for code compliance, clearance requirements, and structural impact. You receive a prioritized list with exact sheet references.

What penetration conflicts does Helonic detect?

Helonic detects ducts, pipes, and sleeves that pass through structural members or rated walls without a coordinated opening.

• Beam penetration detection. Identifies ductwork, piping, and conduit routed through steel or concrete beams where penetrations may compromise structural capacity or violate clearance zones.
• Column clearance verification. Checks that MEP routing maintains required clearances from columns, especially at beam-column connections where reinforcement congestion is highest.
• Slab opening coordination. Maps floor slab openings against MEP riser locations and verifies that openings are properly sized, reinforced, and coordinated with the structural engineer.
• Sleeve sizing validation. Compares specified sleeve sizes against the actual pipe or duct passing through, ensuring adequate annular space for insulation and firestopping.
• Structural capacity impact. Flags penetrations that occur in critical zones such as the middle third of beam spans or near column capitals where structural capacity is most affected.
• Multi-discipline overlay. Simultaneously checks mechanical, electrical, plumbing, and fire protection against the structural system to catch conflicts that single-discipline reviews miss.

Why are unauthorized penetrations so expensive?

Unauthorized penetrations through structural elements are among the most expensive coordination failures on a construction project. When a subcontractor cuts a hole through a beam in the field, the fix typically involves steel reinforcement plates, re-engineering, and schedule delays that ripple across the project.

Traditional plan review catches some penetration conflicts, but the sheer volume of MEP routing across dozens of sheets makes it nearly impossible to verify every crossing manually. Helonic automates this cross-referencing, checking every beam, column, and wall against every pipe, duct, and conduit to surface conflicts while they are still lines on paper.
