Electrical coordination problems rarely announce themselves early. They show up on site — when a cable tray collides with a structural beam, when conduit runs out of clearance in a congested ceiling void. At Bimacme, we solve all of this before installation begins.
We build electrical models in Autodesk Revit to the LOD required by your project — from LOD 200 schematic routing through to LOD 400 fabrication-ready models. The model reflects actual equipment dimensions, manufacturer data where available, and code-required clearances from BS 7671 (IET Wiring Regulations) and local authority requirements.
We receive the electrical design drawings and any available Revit models, confirm the BEP coordination requirements, and establish the LOD and deliverable format before work begins.
We build or develop the electrical model in Revit with accurate geometry, equipment data, and clearance zones. Where the design is schematic, we develop routing to coordination-grade geometry based on available ceiling heights, structural grid, and spatial constraints.
The electrical model is combined with mechanical, plumbing, structural, and architectural models in Navisworks. Discipline models are checked for coordinate alignment before clash testing begins.
We run systematic clash tests covering hard clashes between cable tray and ductwork or structure, clearance clashes between containment and adjacent elements, and maintenance access zones around switchgear and distribution boards.
Every clash is documented with location, disciplines involved, severity, and a recommended resolution. Clash reports are issued to the relevant trade for action, and resolutions are confirmed in the model before the zone advances.
Coordinated electrical layout drawings are issued by zone. Drawings include containment routes with levels, hanger positions, and connection points at panels and equipment.
Zones are formally signed off once all clashes are resolved and the model reflects agreed routes. No zone is released until the coordination record is complete.
It depends on the project stage and contract requirement. LOD 300 covers schematic-level routing suitable for design coordination. LOD 350 adds support structure, sleeve locations, and clearance zones — the minimum standard for construction-phase coordination. LOD 400 includes fabrication-ready containment dimensions, manufacturer-specific switchgear data, and spool-level detail where required. We confirm the appropriate LOD during project onboarding.
Yes. A significant part of our work involves developing Revit models from 2D AutoCAD drawings, schematic layouts, and equipment schedules. We build the 3D model based on design intent, applying routing logic and clearance requirements to produce a coordination-ready model. We document all assumptions and flag areas where design clarification is needed before proceeding.
Yes. All electrical models are built with BS 7671 clearance requirements incorporated as coordination constraints. We also reference CIBSE Guide K for lighting and CIBSE TM50 and SLL guidance where applicable. For projects with specific authority-having jurisdiction (AHJ) requirements, we work to whatever standard is specified in the project BEP.
Yes. Life safety systems — fire alarm, emergency lighting, PA/VA — are typically modeled and coordinated as a separate discipline layer within the federated model. This allows routing conflicts with those systems to be identified independently and ensures the coordination record reflects the regulatory separation requirements between life safety and general power systems.
For a single floor plate in a commercial building, electrical coordination typically takes two to three weeks from model intake to construction release, assuming weekly meeting cadence and timely design responses. Larger and more complex projects — multi-storey residential blocks, mixed-use developments, hospitality — are scoped individually based on floor count, ceiling plenum density, and MEP system complexity.
