Construction management is a professional service that provides a project’s owner(s) with effective management of the project's schedule, cost, quality, safety, scope, and function.

Construction managers oversee and lead a range of building projects from beginning to end. They are responsible for setting and keeping schedules, monitoring finances, and making certain that everybody is doing what they should, every day. Construction managers also help ensure that the workplace is free of safety hazards, and they deal with the various working relationships that exist on a job site.

The specific tasks of a construction manager can vary from project to project, but many roles are standard for the position.

Quality management.
Construction projects quite often involve a number of contractors and subcontractors. One of the most important jobs of the construction manager is making certain everyone is doing quality work and not cutting any corners along the way.

Cost management
A good construction manager is constantly on top of costs and makes the necessary adjustments when unexpected complications or issues arise.

Safety management.
Construction managers must identify and eliminate possible hazards for the safety of everyone on the job site.

Contract administration.
It is the job of the construction manager to ensure that every provision of the contract is being met and that all parties involved are satisfied.
Beyond everything else, construction managers need to keep all parties involved well informed throughout the whole project. This includes the client, the architect, and any contractor or subcontractors involved. If issues arrive, the manager must be ready to deal with them immediately. They also receive specialized training in subjects like site design and planning, enforcement of building codes, scheduling, and cost estimation.
