*2.1. Construction Project Management*

The construction sector brings together all the activities of the design, construction, operation, and demolition of public works, civil engineering, and building works. The vast majority of construction projects follow a sequential development where each of the stages corresponds to a phase of the project. There are four main phases covering the life cycle of a built asset: Pre-project, Pre-construction, Construction, and Post-construction [45]. At each stage of the project, different actors are needed to plan, execute, and control the activities. The complexity of construction projects lies in their rapid pace [46], their unique environment (regulations, location, type of market, etc.) [47] as well as the multiplicity of stakeholders with different roles and periods of intervention [48].

To successfully manage a project, effective planning in all its phases is essential. The corresponding tools and methods can be counted by the dozen, and they must be adopted and put into practice by all of those involved in the construction industry in order to facilitate coordination and time control [49]. The most commonly used tools and methods are detailed in the next section.
