The procedures and methodologies that shall be employed herein shall be done in accordance with the Project's Technical Specification, the Rules and Regulations of the Local Authority, and the latest standards as set forth by the Qatar Construction Specifications. Importantly, all testing and commissioning works shall be done in a safe manner so as to avoid danger to people and to the equipment. Testing and commissioning must be carried out in sequence as set out below: Stage 1:
Tests before connection of Electrical Supply - To carry out all visual inspection and electrical tests to ensure that all electrical equipment like panels , board sand devices, cables and wires, etc., are completed prior to the supply or connection of power.
Stage 2:
Pre-commissioning Test - To carry out all pre-commissioning test to demonstrate that all electrical equipment or devices are properly operating in accordance with its required function.
Stage 3:
Commissioning Test - To carry out the full commissioning test to the following electrical systems: A) Main Power System B) Lighting and Small Power System C) Earthing & lightning Protection system.
