Construction management and commissioning have been deeply embedded in the Assystem Group's DNA for nearly 60 years, having worked on many complex infrastructure construction projects around the world. We are experts in the preparation, planning and coordination of site operations, construction supervision and commissioning and transfer to operator. During each phase, we have the capability to use our design skills to take charge of the site engineering required for final adaptations.
We provide construction management and commissioning services as Owner Engineer or Architect Engineer. We mobilise our experts to ensure safety, quality, performance and compliance within budget and deadlines.

Construction engineering experts, focused on future operator expectations
Managing the construction of infrastructures with major industrial or safety impacts requires the implementation of specific expertise and tools:
Organisation, planning and coordination
Management of the entire construction cycle and assembly phases
Management of subcontractors operating on site
Safety inspections and quality control
Supervision of testing and equipment qualification
Support for commissioning and transfer to operators
Systems engineering approach to optimise productivity and knowledge sharing on and off-site, using collaborative digital tools (modelling, BIM, digital twin, etc.)
A global approach to meet customer requirements:
Precise definition of project objectives and requirements
(operational availability, safety/security, etc.)
Anticipation of risks, avoiding delays and cost overruns
on complex and/or large-scale projects
Optimised agility and coordination
to anticipate and allocate appropriate resources
Contract and supply chain management
With greater need for integration at a local level and the constant pursuit of greater competitiveness, contractors face new challenges: managing the skills development of operators, integrating new benchmarks for existing subcontractors, and managing the impact of changes in different local cultural and contractual settings around the world.
A subcontracting strategy in line with the real capacities of the supply chain
Based on our international experience and functional approach, Assystem supports its clients from the start of the work package allocation phase, ensuring their outsourcing strategy matches the true capacities of the supply chain.
Our teams also ensure technical and legal management of contracts, advising on the correct use of contractual agreement templates proposed by the FICIC (International Federation of Consulting Engineers) for their reliability and legal validity internationally.
Our main solutions for contract and supply chain management:
Assessment of suppliers and providers
Skills development, training processes, HR support
Digitalisation of management modes
Technical and legal management of FIDIC contracts
Inspection and verification of suppliers and providers
Testing and commissioning
The testing and commissioning phase is the last stage before delivery and guarantees the operation, performance, and safety of installations. This phase is key to ensuring the compliance of the installation compared with expectations to guarantee adherence to safety requirements.
A functional approach to deliver fast and effective commissioning
Our approach to managing installations is based on planning, progressive implementation, and the involvement of the operator as soon as construction is completed to ensure a swift, effective handover process.
This methodology is based on a geographical and functional map of the facility, validation by the suppliers (particularly for instrumentation and control), a rigorous facility handover process between construction and testing, and progressive activation from elementary functions to primary functions. These steps help to quickly identify non-compliances so they can be remedied quickly.
Our main solutions to support testing and commissioning:
Timing, planning and performance of tests
Test systems and test benches on supplier premises
Integration methods for infrastructure operator
Test simulation (software platforms)
Assessment of test phase results and commissioning results
Anticipating and preparing shutdowns during the operational phase
During the lifecycle of installations, shutdown phases are needed for maintenance operations to take place or for new equipment to be integrated.
Mastering the management of shutdowns is vital for operators to maintain strong continuity of service. Precise planning and control of recovery operations is central to successful shutdowns.
A flexible approach and turnkey solutions to optimise shutdowns
We offer a range of methodologies and tools to enable supervision and safety of shutdowns, such as Assystem’s own bespoke digital solution which optimises and improves complex schedules: Optimizio*. This solution increases the reliability of complex schedules, making resource management more efficient and aiding decision making.
