Design, planning, permitting & construction of practically any type of commercial building is what O'Leary Group delivers. We start with site selection, site planning and local land use approvals, building design, engineering and construction. The design-build method means project costs are established very early on in the project to save time and money. In today's commercial building environment the need to have a team of knowledgeable, efficient and experienced site planners & engineers, architects, designers, trades contractors and construction managers is needed to get your project finished on time and within budget. O'Leary Group is the Single Source for building construction.

Green building trends and LEED (Leadership in Energy and Environmental Design) are the new buzz words for construction today. O'Leary Group and Butler Manufacturing can bring energy efficient design through LEED certified professionals to your building.
