Commissioning and maintenance

We ensure full commissioning of the work for all of our construction and design-construction projects. We also offer operation and maintenance services to operate your facilities, whether it be services for existing facilities or the integration of these services to your construction project. Furthermore, we can provide full involvement throughout the lifecycle of your projects given that we can complete the demolition of your infrastructures and the rehabilitation of your sites.

Our approach combining all services from the pre-project stage offers an important advantage during post-construction since it benefits from the information and experience acquired at all stages of the project.


To ensure safe start-up and conclusive results, we complete this critical step of the project thoroughly and methodically, according to the commissioning plan established. Our contractual approach is enriched by the involvement of all parties in the achievement of performance objectives and the correction of deficiencies including the designers, specialized contractors and suppliers. The purpose of this approach is to offer a quality project that fully satisfies our client and provides ongoing support for a successful transition during the operation process. To do this, we prepare complete, structured and comprehensive documentation combined with staff training for efficient handling.
