Our Legacy

The story of Joseph B. Callaghan, who founded this company on New Year’s Day, 1967, with about $200 in his pocket, is in many ways a great American success story. The son of immigrants —mother, a nanny from England, father, a Sun Shipyards welder from Ireland who died of pneumonia in 1941 at age 36. He left five children with another on the way. An aunt moved from England to help with the family. After graduating from Roman Catholic high school in 1951, Joe was working in a neighborhood butcher shop and the English aunt, a waitress at a Bellevue-Stratford Hotel restaurant, asked a regular customer if he might have a summer job for her nephew. The customer worked for the prestigious Thalheimer and Weitz architectural firm. It was there that Joe got his first taste of structural engineering. He was hooked. He earned a master's degree in civil engineering from Villanova University in 1963, and after four years with the Schupack and Zollman structural engineering firm, he struck out on his own. Nine years later, he won his first contract from the University of Pennsylvania, by 2015, he had completed more than 550 projects for the university, Philadelphia’s largest employer. One of those projects, Franklin Field, won an award from the American Council of Engineering Companies of Pennsylvania.
JBCI Consulting Engineers becomes incorporated in 1974. Joe wins his first Engineering in Excellence Award (1983) given by the Consulting Engineers Council of Pennsylvania, for Transfer Station No. 1, Chester Township, Delaware County, PA Alterations and Additions.

Joe moves his office and staff to the esteemed Suburban Station Building and after renovations, to our current office space on the 16th floor. Joe also reaches the milestone of 1000 projects with University of Pennsylvania Franklin Field Structural Rehabilitation and hires our current Administrative Assistant, Tina Brooks.
In 1992, Joe celebrates 25 years of industry experience at Overbrook Country Club, continues working on The University of Pennsylvania Franklin Field Stadium, Upper North Grandstand Rehabilitation and Cathodic Protection System Installation, where he won an Engineering Award of Excellence one year later (1993).
