Structural engineering for plant work that has to get built.
Clear calcs and constructible drawings for platforms, pipe racks, expansions, inspections, and plant modifications — plus hoist and equipment structures when the job needs them. Field-aware design that installs cleanly.

Services
Practical industrial scopes for millwrights, mechanical contractors, fabricators, crane installers, and plant engineers — clear assumptions, buildable deliverables.
Pipe racks & supports
Pipe racks, utility supports, and attachments coordinated with routing, hanger loads, and construction access.
Building expansions
Additions, framing mods, and tie-ins that respect existing structure, foundations, and outage windows.
Inspections & assessments
Condition reviews, capacity checks, and strengthening options when existing steel has to take new loads.
Hoist & equipment structures
Runway beams, equipment supports, and foundations — part of the same industrial practice, not a sideline.
Calcs & drawings
Calc packages and drawing sets from sketches and redlines — checked for clarity and constructibility.
Who we serve
Industrial partners across the Upper Midwest who need professional structural packages that install cleanly.
Millwright & mechanical contractors
Platforms, supports, and plant mods coordinated with your install sequence and outage windows.
Hoist/crane installers & fabricators
Runway beams, equipment structures, and connection details ready for shop and field.
Plant engineering / owners
Capacity checks, expansions, and modifications for Upper Midwest facilities — practical judgment on the load path.
What you receive
Deliverables built for construction — not shelfware.

About
Stillgrove Structural is the industrial structural engineering practice of Duane Fuhrman, PE — built for the plant work contractors and facility teams need: platforms, pipe racks, expansions, inspections, and practical modifications.
With more than fifteen years in manufacturing and plant environments — including hoist program leadership at a major manufacturer — Duane brings field-aware judgment to every package. Stillgrove is a young firm standing up around that experience: modern analysis and drafting tools speed delivery; quality still rests on direct supervision and professional responsibility. Licensed Professional Engineer in Minnesota, Wisconsin, and Iowa.
You work with the principal on the job — not layered through a large office.
Stillgrove provides structural engineering only — not fabrication, erection, or millwright work.
