If you follow my ramblings in AutomatedBuildings.com and Engineered Systems, you will understand that the concepts and approaches to applying the new open networked building controls with connection to the enterprise are extremely varied. For example, comparing a wireless system to a wired system or a purchased solution that includes a Web services approach can radically change the total design concept, its cost, and the necessary support infrastructure. With all of these dynamics, how do we ensure procurement of the latest and greatest in building automation features that provide our client with the greatest value?
To follow this model, the conventional controls contract was removed from the various fragmented building contracts. An RFP document that included the owner's mandatory requirements and the mandatory control points as defined by the building design team, was prepared by the owner/user and her specialized automation consultant. Removing this work from the plan and spec world had many advantages. One of the biggest was the purchase of current capabilities. The design time for a large project from inception to completion is often several years, allowing mammoth changes in automation capabilities and reach as well as the building owner's requirements. Just in time, automation procurement ensured the latest and greatest at the lowest cost.
