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.
Plumbing Services – LOD 100 → Concept (Early Vision)
Meaning: High-level plumbing intent without system commitment.
Includes: Conceptual zoning for domestic water, sanitary, storm, and fire water systems shown as basic risers, shafts, and service zones aligned with building massing and orientation.
Outcome: Rapid feasibility validation, early utility demand checks, preliminary shaft planning, and confident go/no-go decisions before detailed engineering.
Critical Insight: Early plumbing clarity prevents major space and routing conflicts later.
Plumbing Services – LOD 200 → Early Design (Schematic Design)
Meaning: Organized but flexible plumbing layouts.
Includes: Approximate routing for water supply, drainage, venting, storm systems, preliminary pipe sizing, fixture zone assumptions, and coordination intent with structure and architecture.
Outcome: Clear system intent, realistic early plumbing cost estimates, drainage logic validation, and early stakeholder alignment.
Critical Insight: Most early plumbing coordination risks are resolved here.
Plumbing Services – LOD 300 → Detailed Design (Accurate & Coordinated)
Meaning: Fully defined, coordinated, and constructible plumbing design.
Includes: Accurate pipe sizes, slopes, invert levels, fixture connections, equipment placement, access clearances, and coordinated interfaces with architectural and structural systems.
Outcome: Significant clash reduction, fewer RFIs, smoother authority approvals, and predictable construction documentation.
Critical Insight: This stage prevents the majority of plumbing-related site conflicts.
Plumbing Services – LOD 350/400 → Build-Ready (Fabrication Precision)
Meaning: Fabrication- and installation-ready plumbing detail.
Includes: Pipe supports, hangers, sleeves, embeds, penetration details, slope control, sequencing clarity, spooling readiness, and fabrication tolerances.
Outcome: Faster shop drawing approvals, minimal site rework, controlled installation, accurate prefabrication, and zero guesswork for installers.
Critical Insight: Converts plumbing design into installation-ready certainty.
Plumbing Services – LOD 500 → As-Built (Verified Digital Twin)
Meaning: Final verified model reflecting actual installed plumbing systems.
Includes: Confirmed as-built routing, invert elevations, valve locations, equipment data, field changes, and validated site conditions.
Outcome: Accurate facilities management, reliable future modifications, asset traceability, reduced maintenance risk, and long-term lifecycle value.
Critical Insight: Becomes the owner’s trusted plumbing reference for decades.
This LOD framework ensures complete clarity, predictable coordination, and zero surprises across design, fabrication, and construction — giving every stakeholder the right information at the right time for faster decisions and smoother project delivery.

“They saved us $320k by detecting clashes we missed. Our project stayed on budget and ahead of schedule.”
“The 5-Point Audit opened our eyes to inefficiencies costing 12% of staff hours. Fixed in weeks.”
“We avoided $450k in rework costs on a hospital project. Their clash detection was a game-changer.”
“Their audit showed us errors that would have delayed delivery by 3 months. We finished 27% faster instead.”
“We reduced our MEP coordination issues by 40%. That alone saved us $180k on a single project.”
“Our bidding accuracy improved overnight. We now win projects with 20% tighter estimates—with zero margin surprises.”
“The BIM model caught 38 clashes in our structural design. That saved weeks of onsite chaos and $220k+ in labor costs.”
“They helped us save just $55k on a small residential project. But for us, that covered nearly our entire profit margin.”
“Before, we spent months fixing mistakes onsite. With their workflows, we reduced field errors by 60% and saved $500k.”
