Why Do Structural Engineering Firms Outsource BIM Modeling and Engineering?
Most structural engineers and contractors do not come to us for a generic service. They come because of a specific situation:
- Their in-house structural team is at capacity and a contract deadline cannot move
- They are on a design-build project where fast clash-free structural coordination is non- negotiable
- They need Scan-to-BIM for a structural retrofit but lack the point cloud processing workflow
- They need rebar detailing and bar bending schedules for a reinforced concrete project
- They need a long-term outsourcing partner across multiple projects — not a one-time vendor
- They need a partner who can quickly understand project requirements and deliver structural BIM services that align with their documentation standards and BIM Execution Plan (BEP)

Structural BIM Levels of Development (LOD) — What Each Level Means
We work to the LOD your project requires — from early coordination models through to fabrication-ready documentation.
| LOD | Stage | What It Means | Best Used For |
|---|---|---|---|
| LOD 100 | Concept | Symbolic — approximate massing and load paths | Early feasibility, structural concept |
| LOD 200 | Schematic | Generic member sizes, approximate geometry | Design development, structural layout |
| LOD 300 | Technical | Accurate geometry, sizes, connections, schedules | Construction docs, permit submission |
| LOD 350 | Coord. | Full inter-discipline interfaces, hangers and supports | Multi-discipline coordination, contractor review |
| LOD 400 | Fabrication | Fabrication | Fabrication-ready — exact specs for manufacture | Steel fabrication, precast production, rebar cutting |
| LOD 500 | As-Built | Field-verified installed conditions | Facility management, structural record models |

Project Experience
Applications across Disciplines
We deliver detailed and coordinated Structural BIM Modeling Services that support design accuracy, collaboration, and construction efficiency across multiple disciplines.
We support architectural teams by producing structural models aligned with design intent. Our models ensure dimensional accuracy, coordinated layouts, and compliance with design standards—helping architects make informed decisions early in the process.
Interior design teams benefit from precise structural layouts that confirm feasibility for partitions, openings, ceiling systems, and load-bearing connections. Our BIM models help identify constraints before fit-out planning begins.
We help MEP teams align their equipment, ducts, pipes, and cable trays with structural systems. Detailed interference checks help prevent clashes between beams, slabs, and MEP layouts, improving installation efficiency.
Contractors receive well-coordinated structural models that reduce site queries, prevent rework, support quantity takeoffs, and simplify construction sequencing. Our models integrate BOQs and fabrication-ready details wherever required.
Our BIM models capture structural elements with precise dimensions, reinforcing details, and design parameters—reducing design errors and RFIs.
BIM-based processes speed up drawing creation, change management, and multi-discipline coordination, helping teams avoid delays.
We run clash checks with architectural and MEP disciplines to eliminate inconsistencies and ensure smoother construction planning.
Optimized structural models reduce rework, material wastage, and unplanned design revisions—improving cost predictability.
Early-stage BIM analysis helps understand load paths, constructability, and design feasibility, supporting faster approvals.
