How we help

Bring us in wherever you need us

Lammers Construction & Design was built out of 20+ years spent on both sides of the table — as a licensed engineer, and eventually as the leader of a design-build construction firm. Along that path, we've worked on everything from assisted living facilities to mass earthwork, landfills to heavy highways, manufacturing to distribution, athletic facilities to airplane hangars, agricultural barns to multi-story offices. That range showed us how complex construction can be — and we found real satisfaction in making the process simpler for the people working through it.

We're not strictly an architecture and design firm, we're not a general contractor, and we're not a construction manager — we live in the intersection of all three. That's what lets us build a customizable experience and act as your guide through the entire process: bringing real-world results, structure, insight, and the ability to unite teams around goals that benefit the whole project.

Because that guide role is backed by an actual engineering license, we can step in as Engineer of Record when a project calls for it — design, stamping, and construction oversight running through one accountable person instead of being handed off between separate firms.

Too often this industry asks you to spend significant money upfront before you have any real cost certainty, or pushes you to commit to a contractor early, before you've had a chance to dig into the details. We wanted a different approach — more affordable and genuinely customizable, so the project stays yours, and you bring in the right teammates at the right cost level as your concept, design, and budget develop.

Every project is different, and so is what you need from us. Maybe it's a quick concept sketch, a permit set for a garage, a second opinion for a team that's already underway, or a full partner from the first floor plan through the final punch list. Bring us in wherever adds the most value — we're just as glad to hand off cleanly to whatever's next.

Concept Generation

We sit down with you as the owner and shape your vision into a real plan — floor plans, elevations, and the overall look and feel of your project.

Architectural & Structural Design

Permitting documents that get your project moving — including structural design for pre-engineered metal buildings — whether that's the next step after a concept or the only piece you need from us.

Engineer of Record & Design Coordination

As a licensed PE, we can serve as Engineer of Record on more complex builds, becoming the central hub that coordinates every discipline into one unified plan.

Owner's Rep, Preconstruction

When you're ready to build, we handle budgeting and contractor selection on your behalf.

Owner's Rep / Construction Manager

Or, if you want us to see it through, we stay involved through the entire construction process to make sure everything gets built the way it was designed.

About

I'm AJ Lammers, a licensed Professional Engineer based in Wooster, Ohio.

Before starting Lammers C&D, I spent over 20 years on the construction side — leading a design-build general contractor and managing sales, estimating, and delivery on commercial projects. That background is what shapes how I consult: I've sat on the owner's side of the table, so the engineering I deliver is built to actually get permitted and built, not just to look right on paper.

Lammers C&D takes on the engineering, stamping, and consulting work that homeowners, small contractors, and commercial clients need — without the overhead of a large firm. You work directly with me at every stage — no hand-offs to junior staff, no layers between you and the person managing your project.
