Services
One contractor for every building system, from design and value engineering through installation and commissioning to maintenance.
Every building system under one contract
Founded in 1978, SECCO installs the systems that make a building work: air conditioning and ventilation, power and communication, water, drainage and fire protection, and the high-voltage supply that feeds them. Around the installation we also provide design and value engineering, testing, commissioning and maintenance.
For owners and developers this is a one-stop MEP service, from the electricity supply to the chilled-water supply, including extra-low-voltage (ELV) and backup systems. The group also has two specialist subsidiaries: SECCO HV for high-voltage and infrastructure projects, and Grand Intersec for condominium buildings.
