Mechanical Completion

It is a process to deliver completed systems to Commissioning for functional testing. It has duty to collect all inspections and pack them to prove to clients that construction is completed as per the engineering and design.


It is a process of testing the system, certifying that functionalities are in accordance with Final User’s expectations. Commissioning will then deliver the system to a Final user.

Why do we offer Mechanical Completion & Commissioning Services?

Mechanical Completion & Commissioning appears at the end of a project, not continuously during its life-cycle; our field experience shows that for clients (Main Contractors and end users) it is not always convenient to deploy “in-house” expertise, but the outsourcing of database, coordinators, supervisors, technicians is a preferable solution.

It’s a critical process, it’s a bottleneck for all disciplines (Civil, Structure, Piping, E&I, Painting) and at all phases (Engineering, Procurement, Construction) of a project. Project schedules are always tight, and the overlap with construction causes a huge impact on the progress.
