Design-Build, Preconstruction & BIM Services in Wisconsin.
Early cost input, coordinated 3D models, and in-house crews who build what we plan.
WIL-Surge Electric is a design-build contractor for electrical, mechanical, and civil work. We bring preconstruction, estimating, and BIM modeling in-house, then deliver the work with our own crews, so the team that plans your project is the team that builds it.
What Is Design-Build?
In design-build, one team carries a project from design through construction under a single contract. Instead of handing a finished design to separate trade contractors, owners and general contractors work with a partner who shapes the design, prices it, and builds it.
For our clients, that means one accountability chain from preconstruction to closeout: one schedule, one point of contact, and quality that stays ours to own across the electrical, mechanical, and civil scopes we self-perform.
Preconstruction & Estimating
Good electrical work starts before the first conduit is set. Our preconstruction support and budgeting give owners pricing they can plan around, and give general contractors a partner who has already worked through scope and coordination before the bid.
Preconstruction is led by Tyler Lowe, our Project Manager & Estimator. A real estimator reviews every request and calls with clarifying questions within one business day. Send plans and specs to estimating@wilsurge.com.
VDC & BIM Modeling
Virtual design and construction (VDC) lets a project be built on screen before it is built in the field. Our in-house BIM specialists use CAD and 3D modeling in Revit to bring design-build projects to life from creation to analysis.
Because we model the electrical scope in 3D, clashes with other trades show up in the model, not on the job site, before they cost you change orders. Our crews then build from those coordinated models, so fewer surprises reach the field.
Coordination in the model goes beyond pipes and conduit crossing paths. It also checks that electrical rooms and mechanical spaces have the working clearance equipment needs, that ceiling space can hold the ductwork, cable tray, and lighting planned for it, and that large equipment has a clear route into the building when it is time to set it.
Prefabrication
We prefabricate assemblies in-house, building them in a controlled setting and delivering them ready to install. Prefabrication shortens installation time on crowded job sites, and because the assemblies are built from the same coordinated models, they fit the way the design intends.
Work that moves off the job site also reduces congestion where space is tight, keeps more tasks out of the weather during Wisconsin winters, and lets field crews focus on installation and connections rather than assembly. Deciding what to prefabricate is part of planning, so the model and the schedule are built with it in mind.
How a Design-Build Project Is Sequenced
Most design-build projects follow the same basic path. It starts with the owner's program: what the building needs to do, who will use it, and what equipment it has to support. From there, early concepts are priced against the budget so the team knows whether the direction is realistic before detailed design begins.
As the design develops, the electrical layout is modeled and checked against the other trades and the architecture. Once the model is coordinated, construction documents are finalized for permits and local review, and crews build from the same information the designers worked from. Closeout follows inspections and final walkthroughs, with the owner receiving a building whose systems were planned together from the first sketch.
What Owners Should Have Ready
The more a design-build team knows early, the more reliable the first budget will be. Before preconstruction begins, it helps to gather a clear description of how the space will be used, the target schedule, and a working budget range. For additions and renovations, existing drawings, past service records, and photos of electrical rooms and mechanical spaces save time and reduce unknowns.
Owners should also think about the future. Planned expansions, new equipment, or growth in headcount all affect how service, distribution, and mechanical capacity are sized today. Naming one decision-maker on the owner's side keeps questions moving, so design choices are settled in days instead of waiting in an inbox.
Why Early Cost Input Matters
The biggest cost decisions on a project are made early, when a line on a drawing can still move without a change order. Pricing options during design lets owners compare choices such as equipment locations, feeder routing, or system types while there is still time to act on the answer.
Value engineering works best at this stage, too. Instead of cutting scope late to hit a number, the team can find savings that keep the design intent intact, such as shorter runs, smarter room layouts, or assemblies that are easier to prefabricate. When the people estimating the work also build it, those numbers reflect how the job will actually go together in the field.
Planning Around Occupied Buildings
Not every project starts on an empty site. Renovations and additions in buildings that stay open need a plan for how work is phased, where crews stage, and when systems can be shut down and brought back online. That planning belongs in preconstruction, not in the field.
Modeling existing conditions alongside new work helps the team spot tie-in points and sequence each phase before crews arrive. It is the same kind of planning behind our electrical work in the occupied 151,000 ft² Waukesha County Courthouse, where our team designed a plan to route new feeders through crawl tunnels beneath the building.
