The Walter Fedy Partnership (TWFP) is a multi-disciplinary consulting firm with two offices in Kitchener, Ontario, and provides architectural, engineering, and construction services. The firms building engineering department performs services for new and existing structures. TWFP has been asked by Cadan Inc. (Cadan) to determine the compatibility of an existing structure for renovations and additions. Cadan is a Toronto based developer that focuses on conversion projects that have a positive social, economic, and aesthetic impact. The existing structure is Lang Tannery, a 150 year old tannery located in Kitchener, Ontario. Cadan intends to convert the old tannery into office and commercial space while maintaining the historic look of the building. They intend to install new rooftop mechanical units and pour additional concrete at each floor. TWFP has been asked to analyse the existing structure and determine if it is adequate for these additions. If the building is determined to be inadequate to support these additions it will be necessary for TWFP to design additional reinforcing for the structure.
Dillon Baratta, a civil engineering co-op student from the University of Waterloo, was asked to analyse the existing structure and determine the strength of the structural members.
This design case is intended for use in a civil engineering steel design course. The case illustrates the procedure for determining if an existing structure is adequate for renovations and additions. It also analyzes an existing structure and determines the strength of the structural members. It could be used to illustrate bending and compression member capacities, which must take into account the age of the steel used in the building. Students could be asked to compute the existing loads on the structure as well as the additional loads being introduced for renovation.
