What is Testing And Commissioning (T&C)?

Testing And Commissioning (T&C) is the process of testing and calibrating the final mechanical and electrical systems to ensure they operate within specified technical parameters and are stable before handover. The T&C process for a project is expected to last from 2-3 months with the main systems: Electrical & Low Voltage, HVAC, Water Supply and Drainage, Fire Protection.

The primary goal of Testing And Commissioning (T&C) Systems in construction projects is to ensure that the entire system and equipment operate correctly, safely, and meet all technical requirements and related regulations. The T&C system ensures that the project is implemented and completed with high quality, optimal performance, and long-term reliability.
