Tesisat

Tesisat is a Turkish term used in construction and engineering to denote the systems and networks that deliver utilities and services within a building. It covers the planning, installation, operation, and maintenance of mechanical, electrical, and plumbing systems that enable essential functions such as water supply, waste disposal, heating, cooling, and power distribution. In practice, tesisat refers to the complete set of building services that run beneath and behind walls and floors.

Key components include plumbing and sanitary systems (water supply, drainage, venting, fixtures); heating and cooling (central heating, boilers, radiators, HVAC); electrical installations (power distribution, wiring, lighting, controls, safety systems); gas supply; ventilation and fire protection; and (where present) data and communications networks and building automation.

Design and execution of tesisat work are typically the responsibility of licensed professionals within the broader field of building services engineering, often referred to as MEP engineering in English. Projects require coordination with architectural and structural plans, as well as compliance with national standards and local building codes. In Turkey, guidelines and standards issued by institutions such as the Turkish Standards Institute (TSE) and related regulations govern installation quality, safety, and energy efficiency. Regular inspection and maintenance are required to ensure ongoing operation.

Origin and usage: The term derives from Turkish words tesis (establishment, facility) and -at, reflecting the organized installation of building services.
