Architects are generally tasked with coordinating the information and work of the design team members. Later in the construction phase a construction manager may coordinate the work of the contractors. Coordination of design and construction is especially essential when building control systems are being integrated, a very critical element of a smart building. It's not enough to simply state in a specification that system A has to be integrated to System B; such pronouncements are too vague, don't identify and detail the responsibility of each party and oftentimes can result in finger-pointing and delays. As the design team leader, the architect should endorse a compliance statement for system integration responsibilities that each of the designers and engineers can acknowledge and insert in their particular specification that would cover the designers as well as the contractors. The statement may address standards for communications protocols, data format, submission of drawings and data points, responsibilities for any hardware, timing of the integration, the contractors' role in commissioning, etc.
