Sometimes called “constructors,” construction managers are in overall charge of planning and coordinating a construction project. The construc- tion manager may work for the general contractor or may be the representative of a separate man- agement firm hired by the developer or owner to oversee the entire project. There are also some self- employed construction managers. A construction manager’s duties usually span the entire life of the project, from conceptual devel- opment to the building’s completion. Working from the project design documents, they oversee all aspects of organization, scheduling, and implemen- tation. Very large and complex projects are beyond the managerial abilities of a single person. In such situations, an overall management firm places indi- vidual construction managers in charge of specific aspects of the job, such as site preparation, steel erection, concrete work, mechanical systems, plumbing, HVAC, and so on. Organizational ability, math and computer skills, and a thorough knowledge of construction pro- cesses are vital to success as a construction man- ager. Managers usually are responsible for creating and adhering to schedules, estimating and project- ing costs, and scheduling the work of the various tradespeople. Communication skills are also impor- tant. Construction managers must be able to effec- tively communicate with everyone involved in the project, from the building owner to subcontractors and their workers. They must also communicate with materials suppliers and government represen- tatives, such as building inspectors. The traditional route to construction manage- ment positions led through the building trades, since the work requires solid experience in various aspects of construction. Increasingly, management firms are seeking candidates who combine such experience with a four-year college degree in construction man- agement or civil engineering. Computer software experience in such areas as CAD, cost estimat- ing, and project management is highly desirable. Certification in this field is becoming more common. Several organizations offer this professional recog- nition based on education, experience, and a written exam. Advancement opportunities are best with large management firms, since a construction man- ager will gain experience and eventually be able to assume responsibility for larger and more complex projects. Upper-level managers in such firms may have broad responsibility for a very large project, supervising the work of a number of construction managers.
