Construction Update: Temple University

Renovations are underway at Temple University’s Conwell Hall and Carnell Hall, Philadelphia. Originally constructed in 1922 and 1928, Conwell and Carnell were intended to be part of a massive collegiate gothic complex similar to the University of Pittsburg’s Cathedral of Learning. An early rendering shows the originally planned Broad Street façade with Conwell Hall on the right and Carnell Hall immediately adjacent to it. The central tower and symmetrical wings were never built, and the land has since been developed for other University buildings including Wachman Hall and Barrack Hall.

Our project includes complete façade repair and replacement of all 670 windows. Phased construction began in late 2015 and will extend to 2017 to allow for continuous occupancy of all areas and to minimize disruption of the active sidewalks adjacent to the buildings.

Conwell Hall is constructed of Wissahickon schist with terra-cotta trim and details. Carnell Hall is constructed of matching schist but has limestone trim and details. Inconsistent masonry repairs have taken place over time and are all being removed. All mortar joints are being raked out and repointed, broken stones are being repaired or replaced, and the severely worn terra-cotta is being repaired and recoated.

Although the buildings are not listed on the Philadelphia Register of Historic Places, the University opted to renovate the facades to meet the Secretary of the Interior’s Standards for the Treatment of Historic Properties. The original steel windows were made by the Pomeroy Company. Over the years, the steel windows have been replaced with aluminum windows of various designs and in many cases the original window heads were lowered to allow for easier installation of ducts, lights, and sprinklers. The new replacement windows will match the historic profiles to the greatest extent possible and will return the windows to their full height.

The design team includes O’Donnell & Naccarato Structural Engineers. The construction is being done by E.P. Guidi. Palmer Inc. and Graboyes Commercial Window Company are the two prime sub-contractors.
