Nos expertises

We support the design of complex construction projects by developing the scheduling of various tasks and the planning of studies and works.

Through constant communication with the project team and analysis of the project’s specific characteristics, we define the critical path, key milestones, technical interfaces, implementation constraints, and contractual execution provisions.

Present alongside the project team and on-site during construction, we ensure rigorous monitoring of the measures and actions established in the scheduling process, as well as the independent, factual, and thoughtful identification of any deviations.

As proactive contributors, we identify solutions that benefit all stakeholders, thanks to our Lean construction approach, which promotes collective anticipation and collaborative work.
