India's largest convention and exhibition centre presented one of the most technically demanding fire curtain briefs BÖLDT has handled: long-span atrium openings up to 35 metres wide requiring continuous compartmentation without any intermediate column support. Accordion fire curtains were specified to follow the curved balustrade geometry of the upper exhibition floors, while automatic fire curtains formed the primary atrium compartment boundaries at ground level. The brief required full concealment during normal operation — no visible head box, no surface-mounted track — to preserve the architectural intent of the interior.

A redeveloped national convention complex combining large assembly halls, exhibition floors and back-of-house service areas, specified with fire curtains for hall subdivision and steel fire doors throughout service circulation.

Core administrative buildings specified with steel fire doors across office wings and stairwell enclosures, meeting compartmentation requirements for institutional occupancy.

All India Institute of Medical Sciences facilities present a specific fire door brief: the 120-minute compartment boundaries at corridor intersections must remain operable for staff movement during normal hospital operation, then close reliably under fire conditions without manual intervention. BÖLDT steel fire doors with electromagnetic hold-open devices were specified for compartment corridor intersections, with glazed fire doors at nursing stations to maintain staff sightlines across compartment boundaries without reducing the fire resistance rating. Hollow metal shaft doors were specified for lift shaft enclosures across multi-storey ward blocks.

Corporate technology campus buildings specified with concealed automatic fire curtains across open-plan atrium and breakout volumes, preserving architectural sightlines while meeting compartmentation requirements.

Institutional training and administrative facilities specified with steel fire door systems across accommodation blocks and administrative buildings.

Public works projects across multiple states specified with BÖLDT fire door systems as part of standard government building fire safety packages.

Public Works Department Delhi building projects specified with fire-rated door systems for stairwell, lift shaft and corridor compartmentation across schools, hospitals and administrative buildings.

Greenfield international airport terminal specified with accordion fire curtains for column-interrupted facade openings and smoke curtains forming reservoirs across the terminal concourse.
