Preconstruction

Oltmans has achieved a significant amount of our success by providing the highest level of preconstruction services available. Our dedicated estimating team’s experience and in-depth industry knowledge, along with the firm’s well-established relationships with the design and subcontractor community, bring the necessary value and foresight to each project ensuring that each product we produce is the best available on the market. We offer a diverse team of estimators on our projects, each with expertise in budgeting, preconstruction, construction, and concrete estimating. We understand that cost control is one of the most crucial areas of responsibility during the estimating process and have well-established systems and procedures to address this.

These services are a part of our delivery process to ensure that our owners get the best value in today’s marketplace.
