Commissioning of a conveyor where equipment is being tested to its maximum rating and capacity of operation.

Project commissioning is the process of assuring that all systems and components of a building or industrial plant are designed, installed, tested, operated, and maintained according to the operational requirements of the owner or final client. A commissioning process may be applied not only to new projects but also to existing units and systems subject to expansion, renovation or revamping.[1] [2]

In practice, the commissioning process is the integrated application of a set of engineering techniques and procedures to check, inspect and test every operational component of the project: from individual functions (such as instruments and equipment) up to complex amalgamations (such as modules, subsystems and systems).

Commissioning activities in the broader sense are applicable to all phases of the project from the basic and detailed design, procurement, construction and assembly until the final handover of the unit to the owner, sometimes including an assisted operation phase.

Objective and impact[edit]

The main objective of commissioning is to affect the safe and orderly handover of the unit from the constructor to the owner, guaranteeing its operability in terms of performance, reliability, safety and information traceability. Additionally, when executed in a planned and effective way, commissioning normally represents an essential factor for the fulfillment of schedule, costs, safety and quality requirements of the project. [3]

Commissioning management systems[edit]

For complex projects, the large volume and complexity of commissioning data, together with the need to guarantee adequate information traceability, normally leads to the use of powerful IT tools, known as commissioning management systems, to allow effective planning and monitoring of the commissioning activities.


The International Association of Commissioning Engineers (IACE) was formed in 2015 by a group of Commissioning Professionals, and launched in January 2016. IACE is preparing accredited qualifications to fill the gap in the academic landscape for Commissioning Engineers.

Independent discipline[edit]

There is currently no formal education or university degree which addresses the training or certification of a Project Commissioning Engineer. Various short training courses and on-line training are available, but they are designed for qualified engineers.

Commissioning for buildings is a specific discipline in itself, and there are qualifications available for this.

Commissioning of large civil and industrial projects is a complex and sophisticated technical specialty which may be considered as a specific and independent engineering discipline.

It can be as important as the more traditional ones, i.e. civil, naval, chemical, mechanical, electrical, electronic, instrumentation, automation, or telecom engineering. Large projects for which this statement can be made include chemical and petrochemical plants, oil and gas platforms and pipelines, metallurgical plants, paper and cellulose plants, coal handling plants, thermoelectric and hydroelectric plants, buildings, bridges, highways, and railroads.
