Penetrations and pads planned before concrete is cut

Misaligned sleeves, missed openings, or poorly sized pads lead to core drilling changes, structural conflicts, and rework on-site.

Our BIM-driven penetration and pad design defines every opening, sleeve, and pad location before construction begins.

Openings and pads defined before site work begins

Penetrations and pads impact structure, routing, and sequencing. We model every sleeve, core, and pad in context with slabs, beams, and services so installation follows the plan without adjustments.

When penetrations aren’t coordinated, problems show up on-site

Our BIM-first approach resolves these issues before construction starts.

  • Openings conflict with beams or structural elements
  • Core drilling locations shift during construction
  • Equipment pads require resizing after installation begins
  • Trades rework routing due to missed penetrations

What you get with our penetration and pad layouts

Our deliverables focus on making openings and equipment bases accurate, coordinated, and ready for execution.

  • Slab and wall penetrations – Openings positioned to match structural layouts and service routing
  • Core drilling layouts – Drill points defined with reference to beams, reinforcements, and constraints
  • Equipment pad detailing – Pad sizes and elevations planned for load support and equipment fit
  • Trade coordination views – Penetrations checked against HVAC, electrical, and plumbing systems
  • Annotated drawings – Clear tagging of opening sizes, elevations, and references
  • Installation sequencing – Layouts structured to match construction order and access
  • Construction-ready models – LOD 350–400 outputs prepared for site use

Inside our penetration and pad coordination models

  • Penetration layouts showing sleeves across slabs and walls
  • Core drilling plans aligned with structural elements
  • Equipment pad layouts with dimensions and clearances
  • Coordination views resolving clashes with MEP systems

Penetration and pad design for every role

Built for contractors and coordinators who can’t afford errors in openings or pad placement.

  • Contractors installing sleeves, cores, and equipment pads
  • BIM coordinators managing multi-trade penetration layouts
  • Designers preparing penetration and pad documentation
  • Field teams executing core drilling and equipment setup

Our penetrations and pads hold up in the field

Because openings and pads only work when they match structure and installation conditions.

  • Penetration locations defined with actual slab and beam constraints
  • Pad sizes aligned with equipment loads and clearances
  • Coordination resolved before core drilling begins
  • Layouts structured to match sequencing and installation workflows
  • Documentation that reduces revisions during construction

 

Every penetration and pad is planned to be built as modeled, not corrected on-site.

Stop fixing penetrations after concrete is in place

Accurate layouts prevent structural rework and delays.

FAQs

  • What is penetration and pad design?

    Penetration and pad design involves planning openings, sleeves, and equipment bases so they align with structure and MEP systems before construction begins.

  • Why is BIM important for penetration modeling?

    BIM facilitates the coordination of penetration without clashes, which avoids rework and constructability.

  • Can Revit model penetrations and pads accurately?

    Yes, Revit penetration modeling offers precise sizing, location as well as placement of penetrations and pads.

  • How do you avoid clashes with penetrations and structural elements?

    BIM coordination of penetrations is used to combine structure with all MEP systems and models.

  • What are equipment pads used for in MEP design?

    Pads prevent the heavy mechanical or electrical equipment and assure the compliance and stability.

  • How does proper penetration planning reduce rework?

    Precise core drilling map is achieved by sleeves and cores alignment at an early stage that prevents conflicts in the construction process.

  • Are penetrations coordinated across all trades?

    Yes, penetrations are synchronized with plumbing, HVAC, electrical, and structure of delivery clash-free.
