O'Leary Construction, LLC. has worked in Tucson and surrounding communities for the last 20 years and has enjoyed a great working relationship with our customers, subcontractors and suppliers.

With an excellent work force, O'Leary Construction has earned a reputation for doing quality work and staying on schedule. O'Leary Construction has skilled operators for earthwork, experienced crews for underground water and sewer work. It has taken us years to put these crews of dedicated employees together.


The O'Leary Construction crews clear the site, install the sewer & water mains, coordinate with local utility companies to install dry utilities such as phone, cable TV, gas & electric. When the site work is complete then we complete the grading and get the site ready for curbs and streets. Our clients like the fact that we do it all when it comes to site preparation.
