NBC 2016:2016 Part 7 is the Indian Standard (BIS) for national building code of india 2016 - construction management, practices and safety. Part 7 covers the how of construction: the project management workflow, site organisation, workmanship standards for each trade, and the construction-phase safety framework. Where Parts 3 to 6 specify the end state of the building, Part 7 specifies how to get there safely and to quality. The Part addresses planning and scheduling; site layout and temporary works; material storage; workmanship and tolerances for masonry, concrete, and finishes; construction safety including scaffolding, formwork, excavation, lifting operations, and demolition; fire safety during construction; and site welfare including sanitation and first-aid. It references a large body of IS safety codes (IS 4014, IS 7969, IS 3764, and the PPE series).
Addresses construction project management, site planning, workmanship practices, quality assurance, construction safety, scaffolding, formwork, excavation, and demolition operations.
Scaffolding sizes, fall-protection thresholds, formwork stripping times, PPE specs, and worker welfare ratios on site.
