Twenty-one delivery divisions. Four engineering excellence centres. One integrated engineering company.
APIS Ltd. operates through two Strategic Business Units, supported by a group of Engineering Excellence Centres, that concentrate technical expertise, optimise processes and deliver integrated, standardised solutions to clients. Every division covers the full Design – Build – Operate – Maintain (DBOM) cycle.
Engineering disciplines, organised for integration.
The unit-and-division model concentrates expertise where it belongs and eliminates overlaps between disciplines. Clients get integrated solutions through a single accountable structure — from buildings and industries to energy and infrastructure.
Building Systems & Technologies Unit.
Integrated solutions for smart, commercial, residential and public buildings. Every system — heating, cooling, lighting, security, automation — works in harmony to deliver comfort, performance and sustainability across the full lifecycle.
