Senior BIM Modeller / Multi-Discipline BIM Coordinator

Contract; contract-to-hire considered for the right person

Duration: 6 months initial, with extension expected based on project pipeline

Experience level: 7+ years in BIM production, with at least 3 years coordinating federated multi-discipline models

Location: Hybrid and/or REMOTE in Houston, TX (transformer manufacturing)

Schedule: 40 hrs/week. Occasional extended hours around fabrication release and site coordination milestones.

Start date: Immediately

1. Why This Role Exists

Our client designs and manufactures the electrical backbone of AI data centers and large industrial sites — three-phase padmount transformers up to 46 kV / 10,000 kVA, medium-voltage substations to 35 kV / 60 MVA, high-voltage substations to 138 kV / 100 MVA, UL 891 low-voltage switchboards, power skids, and pre-engineered data center systems. We are a true OEM: we own the design, the engineering, and the supply chain, and we carry that accountability from specification through energization.

That model only works if the 3D model is the single source of truth. Right now, our design output is bottlenecked at the coordination stage — discipline models are produced faster than they can be federated, clash-checked, and released, which pushes rework downstream into the shop and onto site. We need an experienced BIM coordinator who can absorb that load immediately and bring order to how our models are built, checked, and handed off.

2. Scope of Work

The contractor will own multi-discipline BIM coordination across the following product and project types:

• Electrical: MV/HV substations, padmount transformers, switchgear and UL 891 switchboard lineups, cable tray and busway routing, conduit and raceway, grounding, and equipment working clearances.

• Mechanical: liquid- and air-cooled thermal systems, CDUs, piping and manifolds, ventilation and HVAC for e-houses, enclosures, and whitespace modules.

• Structural / civil: skid frames, structural steel, enclosure and container structures, foundations, pads, and anchor layouts.

• Site and layout: equipment arrangement, access and egress routes, crane and rigging envelopes, maintenance pull-space, and interconnection tie-in points.

3. Core Responsibilities

Model production and federation

• Build and maintain federated models in Revit and Navisworks across electrical, mechanical, and structural disciplines for both factory-built assemblies and site installations.

• Model to the level of development each stage requires — concept LOD 200/300 through fabrication-ready LOD 400 for shop release.

• Reconcile MCAD equipment geometry (Inventor / SolidWorks / STEP) into usable, lightweight Revit families and IFC content without dragging unusable mesh detail into the coordination model.

• Maintain model health: purge, audit, worksharing hygiene, link management, and file size discipline so models stay workable as projects scale.

Clash detection and issue management

• Run scheduled Navisworks clash tests against a documented, versioned test matrix — not ad hoc one-off checks.

• Triage clashes: filter noise, group by root cause, assign to the responsible discipline, and track every issue to closure with evidence.

• Publish clash and coordination reports on a fixed cadence and chair the coordination review meetings that go with them.

• Escalate unresolved interference that threatens a fabrication release date, with a recommended resolution rather than just a flag.

Documentation and fabrication output

• Generate coordination drawings, general arrangements, sections, equipment layouts, and installation details from the model.

• Produce accurate model-derived quantity takeoffs and schedules to support procurement and cost estimation.

• Support the shop with fabrication-level dimensional output and resolve constructability questions from manufacturing engineering.

• Maintain as-built model updates from field markups, point cloud scans, and site feedback.

4. Required Qualifications

Non-negotiable.

• 7+ years of professional BIM modelling experience, with a minimum of 3 years specifically coordinating federated multi-discipline models — not single-discipline drafting.

• Expert
