We hold ourselves to very high standards, and we do our absolute best to live up to them. If we miss the mark, we are the first to notice and the first to resolve it. Clients and subcontractors alike return to work with us again and again because of our honesty and fairness.
The product we build is our legacy and we refuse to produce anything but the highest quality we can achieve. Everything we do adheres to this strict code â€” from the job sites we run to the finished projects we deliver.
Oltmans made its mark perfecting tilt-up construction. While many now imitate our success, we keep moving ahead â€” applying our expertise to new frontiers as we diversify our business and develop new skills. The logistics, accounting and management know-how we amassed refining concrete construction techniques is now driving down costs and raising quality in solar power, infrastructure, historic renovation and retrofits.
