The Oneglia Family

O&G is one of the Northeast’s leading providers of construction services and products.  For over 90 years, O&G has completed some of the region’s most challenging projects and established ourselves as a leader in our industry - and in the communities in which we live and work.

Over 90 Years of Construction Experience

Founded in 1923, O&G has developed an extensive knowledgebase of construction project experience spanning various conditions and environments.  We have successfully completed projects in settings ranging from healthcare, where the site must be kept clean, quiet and safe, to major highway interchanges where commuter traffic presents an uncontrollable variable that must be constantly managed.

An Industry Leader

O&G has consistently ranked as one of the country’s top 400 construction companies for 50 years and we are one of the Northeast’s largest construction companies.  Our clients include some of the most well-respected brands in the region and throughout the world.  Through our industry leadership, we are frequently asked to provide input into industry legislation and participate in industry roundtables.

A Company with Vast Capabilities

From building and road construction projects to mason products and construction materials supply, O&G has a vast set of capabilities and extensive experience that allow us to successfully complete complex, challenging and unique projects on time and within budget.

An Extensive Equipment Fleet

Recognized by industry publications and leading equipment manufacturers like Caterpillar, O&G has one of the most comprehensive and well maintained company-owned equipment inventories in the industry.  Our fleet includes over 1,900 pieces of equipment.  We operate six repair facilities that provide complete, in-house repair capabilities for equipment ranging from cranes and concrete mixers to small power equipment.

A Team with Unparalleled Experience

O&G has one of the most skilled and experienced teams in the industry.  On staff, we have professional engineers, registered architects, field supervisors, estimators and hundreds of skilled tradespeople backed by a company with over 90 years of construction industry knowledge and experience.  The median years of tenure for our staff is 2.5 times longer than the industry median for construction workers in the United States.

A Firm Commitment to Safety

At O&G, safety is more than a slogan.  We take the safety of our employees, our clients and their “guests”, as well as the community, very seriously.  O&G utilizes an aggressive, proactive approach to safety that ensures everyone goes home safe to their families and loved ones at the end of each day.  We have been recognized with 20 AGC (Association of General Contractors) safety awards since 2000 and have received 17 consecutive years of recognition from the CCIA (Connecticut Construction Industries Association) for our industry leading safety practices.

A Family Owned Company

O&G is a fourth generation, family-owned company.  Our ownership actively participates in the daily management of company operations and our projects.  Our management can be seen walking project sites and providing oversight throughout the project lifecycle.

A Dedication to Community

From toy drives to sponsorship's of local little league teams, O&G is dedicated to the communities in which we live and work.  Our staff are leaders in their local communities and contribute thousands of volunteer hours and support to nonprofit and community organizations each year.
