GPI delivers results with an uncompromising dedication to quality.
In 2016 GPI celebrated the 50-year anniversary of our founding. Since its humble beginnings in 1966, GPI has relied upon the reputation and combined experience of its officers and staff to successfully handle projects ranging in size and complexity, some with individual budgets reaching half a billion dollars. During this time, GPI has grown from a two-person consulting firm to a corporation earning the rank of #57 among Engineering News Record’s top 500 national design firms.
