40 / BUILDING DIALOGUE / September 2018 ELEMENTS Renovating Buildings Strategies for Renovating Existing Buildings O ne of the greatest challenges for renovat- ing an existing building is how to cost-ef- fectively maintain operations with mini- mal impact on occupants throughout construction. Renovating existing facilities can be a large un- dertaking complete with budgeting, scheduling, communication, storage and safety consider- ations that ultimately impact operations, tenants and visitors. Whether you are completing a partial reno- vation where some areas of the building need to remain operable or a full renovation where op- erations cannot be taken off line, there are many critical elements to address when planning for a renovation in an occupied building. In most renovations, building occupants need to maintain some if not all program operations during construction, and the strategy for accommodating occupants during construction may need to be a part of the design to minimize impact on occu- pants and operations. The design team, contractor and owner or operator need to determine whether the renovation should be phased to allow for occu- pants to be moved to parts of the building not in construction. This can require multiple moves for occupants and increased construction costs from extending the construction schedule over multiple phases or temporary facilities during construction so that the facility can be renovated in one phase. The Occhiato Student Center case study high- lights the design-build delivery method imple- mented to complete a successful phased renovation of an existing building where temporary facilities were utilized to keep critical campus services in operation, as well as a few key takeaways to guide others undertaking renovations.
