Overview
Redeveloping an existing building for an alternative use can be a challenging task when trying to meet building code requirements. Redeveloping a building which was never intended for residential use and is more than 90 years old brings a completely new (or are they old?) set of challenges. The most common building code that must be considered when designing residential construction is the International Building Code (IBC). Since the building is located within the District of Columbia, the District of Columbia Building Code also applied. One requirement specified within IBC and DCBC is the level of acoustical separation that must be provided between living spaces and adjacent uses. In an existing building that was not designed for residential use, it can be difficult to determine if the existing partitions (i.e. walls and floor/ceiling) will provide the required level of noise reduction to meet IBC. To overcome this challenge, field testing can be completed to determine the partitions’ acoustical performance.
