Cira Centre

The Cira Centre is one of the latest collaborations between Enclos and Pelli Clarke Pelli Architects, who is known for sophisticated facade designs. The tower stands prominently on the west bank of the Schuykill River in the University City district and is the first office tower in West Philadelphia. The tower’s striking design has created an immediate landmark in the neighborhood. At the time of completion, it was the tallest building in Philadelphia outside of Center City.

Enclos designed, engineered, assembled and installed Cira Centre’s geometrically complex curtainwall whose facets and sloped surfaces create an elegant variation on conventional high-rise building form.

The building incorporates a local transport rail hub permitting egress without going outside. The operating commuter line complicated erection logistics on the building site considerably. Enclos worked with Turner Construction Company and the build team to develop a delivery and installation strategy making use of a tower crane atop the building structure. Large curtainwall units were crane-picked and set in place level by level. Enclos designers developed a custom system to facilitate this installation strategy and meet the extremely aggressive scheduling requirements of the project.
