Our story

JHA Design Co was started by two guys with a dream and a work ethic. Both had experience in construction for years prior, but never tried their hand at any business. Through trials, errors, wins and losses, JHA Design Co was ultimately formed into the premier excavation, grading and heavy demolition contractor it is today.

What Sets Us Apart

At JHA Design co, we know that whether we're moving dirt, renovating your yard or demolishing an old concrete slab, the work we do is not as simple as it seems. We're prepared for unexpected obstacles and delays and have a greater set of skills and equipment to solve problems more quickly and for less money, and avoid expensive mistakes and errors that can damage existing property or cause problems with new construction.

We have a vast array of equipment for any type of project to make sure your job is done right, done fast and done better. We use professional grade lasers and surveying tools to meet your specifications and ensure everything is where it should be, how it should be. In addition to our own fleet, we work closely with local rental yards to make sure we have the perfect machine for your specific needs, from compactors and dump trucks to excavators, bulldozers and more.

We know that your project often needs to be exact to a set of plans, not just eyeballed or roughly graded to visual decency. Thats why we use the latest and most accurate lasers and measuring equipment to make sure your project isn't just "good enough" but done right and done better, and that your plans actually transfer to your project without cut corners or sloppy work.

Whether it's a small trenching project or a full grading job, excavation, grading and demolition are some things that can easily drag on without the proper equipment and skillset. Anybody can dig a hole just like anybody can make a dining table, it's whether they do it well that sets professionals apart from the general public. At JHA Design Co, we realize this from the start. Thats why we pride ourselves on high quality and exact work at a fast pace, making sure we get it done as quickly as we can while still doing it right, fast, and better than anybody else out there.
