LOD explains how detailed, accurate, and build-ready your BIM model is at every stage. As the LOD increases, uncertainty drops—giving you clearer coordination, fewer RFIs, faster approvals, reduced rework, and a smoother, more predictable construction process.
Electrical Services – LOD 100 → Concept (Early Vision)
Meaning: High-level electrical intent without detailed system definition.
Includes: Conceptual electrical zones, major riser locations, approximate equipment areas, estimated power density, and service entry assumptions aligned to building massing and orientation.
Outcome: Rapid feasibility checks, early load viability, preliminary utility coordination, and confident go/no-go decisions before detailed engineering.
Critical Insight: Early electrical clarity prevents major capacity and space conflicts later.
Electrical Services – LOD 200 → Early Design (Schematic Design)
Meaning: Organized yet flexible electrical layouts.
Includes: Approximate routing for conduits and cable trays, preliminary panel locations, early lighting intent, load assumptions, and coordination with architectural and structural systems.
Outcome: Clear electrical design intent, realistic early cost planning, demand validation, and strong alignment across disciplines.
Critical Insight: Most early electrical coordination issues are resolved here.
Electrical Services – LOD 300 → Detailed Design (Accurate & Coordinated)
Meaning: Fully defined and coordinated electrical design suitable for CDs.
Includes: Accurate circuiting, panel schedules, equipment placement, lighting layouts, grounding systems, coordinated routing, and reliable quantity take-offs.
Outcome: Reduced clashes, fewer RFIs, smoother authority approvals, and predictable construction documentation with reduced rework and cost certainty.
Critical Insight: This stage prevents the majority of electrical site conflicts.
Electrical Services – LOD 350/400 → Build-Ready (Fabrication Precision)
Meaning: Installation- and fabrication-ready electrical detail.
Includes: Exact conduit layouts, supports, sleeves, embeds, hanger details, penetration coordination, installation sequencing, and prefabrication readiness.
Outcome: Faster shop drawing approvals, minimal site rework, controlled installations, accurate prefabrication, and zero execution ambiguity.
Critical Insight: Converts electrical design into installation-ready certainty.
Electrical Services – LOD 500 → As-Built (Verified Digital Twin)
Meaning: Final verified electrical model reflecting actual site conditions.
Includes: Confirmed as-built routing, panel and circuit data, equipment tags, field changes, testing updates, and validated system locations.
Outcome: Accurate facilities management, safe future modifications, reliable asset tracking, and long-term operational confidence.
Critical Insight: Becomes the owner’s definitive electrical reference for decades.
