BIM Designer, Civil & Underground Utilities

What you'll do

As BIM Designer, Civil & Underground Utilities, you'll own everything that sits below grade and outside the building line in our federated model. Anything from foundations and equipment pads, electrical duct banks and underground raceway, grounding, and equipment yard layout. This role sits inside our growing BIM function, working shoulder-to-shoulder with electrical, structural, and civil designers to keep one federated model as the single source of truth from design through fabrication and field support.

Where you'll work

We are an in-office culture — velocity matters when you're building physical infrastructure, and the best decisions happen in the room. This role is ideally based in our San Francisco, Long Beach, or Houston offices, with full-time onsite expectations outside of bi-weekly WFH Fridays.

That said, we will make exceptions for truly exceptional talent if you live outside one of our hubs. If you're the right person for this role, we'll have a conversation about what works.

Responsibilities

• Model foundations, equipment pads, embeds, and anchor bolt setting plans for transformers, substations, switchgear, and other heavy equipment, coordinated against equipment general arrangement drawings
• Model electrical duct banks and underground raceway — conduit arrangement, encasement, bend radii, spare capacity, manholes, and pull boxes
• Model the grounding system — ground grids, rods, conductor routing, and connections to pads, structures, and fence lines
• Model outdoor structures and equipment yard layout, including electrical clearances, phase spacing, and maintenance access
• Take in Civil 3D surfaces, utility networks, and survey data and reconcile them into the federated model, including shared coordinates and georeferencing
• Own the outdoor and underground models within the federated set and run underground clash cycles — duct bank against foundation, grounding against structure — resolving conflicts rather than just reporting them
• Produce foundation plans, duct bank plans and sections, grounding plans, and yard layout drawings to Giga's CAD standards
• Generate model-based quantity takeoffs for concrete, reinforcement, steel, and conduit to support estimating and procurement
• Build and maintain the parametric family library for repeatable outdoor and underground content — pads, duct bank sections, manholes, and bus supports
