NBC 2016:2016 Part 12 is the Indian Standard (BIS) for national building code of india 2016 - asset and facility management. Part 12 is new in NBC 2016 and addresses the operation, maintenance, and asset management of buildings after handover. It covers maintenance planning, periodic condition assessment, routine and preventive maintenance, energy and water audits, repair and retrofit procedures, and the documentation of as-built and asset data through the building life. The Part is particularly relevant to commercial real estate, institutional buildings, and public buildings where facility management is procured as a service. It provides a common framework for the FM scope of services, inspection frequencies, and asset handover documentation.
Addresses operation, maintenance, and facility management of buildings post-occupancy: maintenance planning, condition assessment, repair and retrofit, energy and water audits, and asset information management.
FM staffing ratios, maintenance frequencies for lifts, DG, fire systems, water tanks, and audit cycles.
