The Philadelphia Cathedral
Of the Episcopal Diocese of Pennsylvania

The work at the Cathedral centered on structural stabilization of the exiting wood floor. A system of steel beams, thru-bolts, and epoxy/steel connections were added to the existing timber floor system. Interior renovations included construction of a new Narthex; new interior finishes in the Nave; and reconstruction of the Chancel. A new mechanical system provides both heat and air conditioning for the new and renovated spaces. Construction of new ancillary spaces included new Restrooms, Choir Room, Vesting Room, Mechanical Room and Electrical Rooms. Another major element in the renovation of the interior space was the design an installation of a new French Limestone floor in the Narthex, Nave and Chancel and a circular Bishops bench, which was constructed on the Chancel from the same limestone.
