CAD Drafting Services in Central Illinois

Supporting project teams across Central Illinois and beyond.

Every construction and renovation project reaches a point where someone needs to work from a drawing. Whether that’s an architect detailing a renovation, a contractor coordinating trades, or a facility manager planning future work — the quality of that drawing determines how smoothly everything that follows goes.

For project teams throughout Central Illinois, The Wassi Group produces accurate, build-ready CAD drawings and coordinated 3D models. As a result, your team gets something reliable to work from — clear documentation, correct dimensions, and files delivered in the formats you actually use.

Why accurate CAD documentation matters

Design and construction decisions start with drawings. When those drawings are inaccurate — dimensions approximated, systems missing, conditions outdated — the errors don’t stay on paper. Instead, they follow the project into the field, where fixing them costs real time and money.

At TWG, our CAD drafting work starts with accurate existing conditions data. For existing buildings, we use the Leica RTC360 to laser scan the project site before drafting begins — so every drawing reflects the building as it actually exists today. For new construction projects, we work directly from design intent — producing coordinated Revit models and drawings from the ground up.

What we deliver

Existing conditions drawings — accurate 2D floor plans, elevations, and sections reflecting the building as it currently stands
Revit models — coordinated BIM models built from verified existing conditions for renovation, design, and construction planning
BIM modeling — coordinated 3D models supporting equipment design, industrial coordination, and facility planning
Industrial facility documentation — existing conditions capture and coordination for piping, equipment, structures, and MEP layouts
3D renderings and visualization — photorealistic Twinmotion renderings that communicate design intent clearly before construction begins
New construction documentation — full drawing sets for residential and commercial new construction projects

Who we work with in Central Illinois

Architects and designers who need accurate existing conditions documentation as the foundation for renovation and new design work
Homeowners and residential clients planning additions, renovations, or new home construction who need accurate, permit-ready drawings
General contractors coordinating trades and sequencing work from drawings that reflect verified field conditions
Industrial and mechanical engineers who require detailed documentation for equipment coordination, facility modifications, and process system planning
Facility managers maintaining commercial buildings, healthcare facilities, and industrial plants who need reliable floor plans and building records
Owners and developers who want clear visual communication of design intent before committing to construction

Our process

Project review — First, we start by understanding your project goals, existing documentation, and the formats your team needs deliverables in
Existing conditions verification — Next, we laser scan existing buildings to capture precise conditions before drafting begins, or work directly from design intent for new construction projects
Drafting and modeling — We then produce CAD drawings and Revit models to the level of detail your project requires, with accuracy as the non-negotiable standard throughout
Delivery — Finally, you receive clean, organized files in the formats your team uses — with clear communication from start to finish

Serving Central Illinois and the Surrounding Region

Based in Morton, IL, The Wassi Group has served construction and design professionals throughout Central Illinois for nearly 30 years. Our team regularly works across the region — including Peoria, Peoria Heights, East Peoria, Washington, Chillicothe, and surrounding communities — as well as broader project locations throughout Illinois and beyond.

Notable local projects include 3D laser scanning, Revit modeling, and Twinmotion rendering for BioUrja’s whiskey barrel warehouse to determine maximum storage capacity, CAD drafting and 3D rendering for Haven on the Farm, mechanical BIM coordination for the East Peoria Police Station, and laser scanning and Revit modeling for The Cathedral of St. Mary for the Catholic Diocese of Peoria.
