Generally, in terms of the FM Service (this may vary from project to project) Project Co is obligated to maintain all building plant, fittings and infrastructure in line with Good Industry Practice. Project Co is also required to replace building fabric, plant and infrastructure when life expired (or to meet handback condition requirements), utilising a periodically agreed Lifecycle Plan and fund. Also, Project Cos have a responsibility to report on energy performance (i.e. energy consumed and costs incurred) and the FM SLS often contains provisions that might assist Authorities in reducing consumption from an operational perspective e.g. to perform its operations so as to minimise Utilities consumption whilst achieving the optimum environmental conditions required by the Authority. A typical service requirement is noted below.
