Switzerland won the contract to build from scratch the largest airport in India in a former agricultural region off the aviation map, and the 3,900-meter runway, licensed in March 2026, paves the way for a megaproject that could reach 70 million passengers per year by 2050 and up to six runways at its maximum expansion.
The new NR 18 is simpler, more straightforward, and easier for authorities to oversee. At a time when construction is leading the economic recovery, there was a need for simpler, less bureaucratic standards that still ensure the health and safety of workers.
The standard now states what needs to be done, not how it should be done. In other words, the responsibility lies with the contractor and the individuals who will care for the health and safety of work.
Companies will have 24 months to abolish the use of the compressed air shaft, a task considered high risk for construction workers. Manual excavations will be limited to a depth of 15 meters.
Additionally, air conditioning will be mandatory in self-propelled machines (with their own movement) weighing over 4,500 kilograms and in crane equipment.
Companies will not be allowed to adapt containers for workers’ living areas, such as cafeterias, changing rooms, or construction offices.
The new standard also brings safer rules for performing excavations and for tasks involving heat, such as welding and grinding.
Modernization of NRs
Since February 2019, in addition to NR 18, NR 1, which deals with general provisions on health and safety; NR 3, about embargoes and interdictions; NR 12, on safety in machinery and equipment; NR 20, about flammable and combustible materials; NR 24, which addresses hygiene and comfort conditions in workplaces; and NR 28, concerning inspections and penalties, have all been completely revised.
NR 2, regarding prior inspection, has been revoked. There has also been a revision of the heat annex in NR 15 and the item regarding the hazard of fuel for personal consumption in NR 16.
Estimates from the Economic Policy Secretariat of the Ministry of Economy indicate a cost reduction of nearly R$ 5 billion in the construction industry over 10 years with the new wording coming into effect.
The calculation is based on information from the Brazilian Chamber of Construction Industry (Cbic), considering the simplification presented by the new text, the possibility of adopting better management practices, and the improvements in health and safety regulations.
