We supply materials for projects throughout New England and the Tri-State region. O&G is one of the largest Heavy Civil Construction firms in the Northeast. We have successfully completed some of the largest and most complex heavy civil construction projects throughout the region and the country.

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. 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.
