The duties and responsibilities of the construction site supervisor sometimes begins from the planning process of the project.
The project manager may require his input or opinion in drafting budget and proposal.
He may also be required to supply the likely cost of materials and labor required to complete a project or a particular phase of the project.
He may assist the project manager in determining the likely duration of the construction work and ways to fast track the project or to reduce cost.
After the planning phase of the project, the construction supervisor takes over the responsibility and coordination of labor and materials to be utilized at the site.
His first duty at this stage is to work out a job schedule for the site workers and subcontractors.
To perform well in this role, the site supervisor must be an expert in construction projects.
