A construction contractor or manager is in charge of many different aspects of construction and is known by any number of titles, including constructor, construction superintendent, general superintendent, production manager, project manager, general construction manager, executive construction manager, general contractor, contractor, and subcontractor. Those serving as construction contractors or managers might actually be the owner or a salaried worker employed by the construction contracting company or just an individual contracted to work for the owner, developer, contractor, or management firm responsible for the build.
Employment is on the rise for construction contractors and managers and is projected to rise much faster than the average for all occupations through 2005 since the amount and sophistication of construction projects is continually increasing. Additionally, a lot of openings will become available as workers leave the field and must be replaced.
Due to the nature of the responsibilites held by construction contractors and managers, they must work on call in order to handle all accidents, delays, and bad weather conditions. A 40 hour week for a contractor or manager is a rarity. When necessary, to meet deadlines, projects may be worked on 24 hours a day for a few days or weeks at a time
The construction industry is divided into three major segments. Construction of buildings contractors, or general contractors, build residential, industrial, commercial, and other buildings. Heavy and civil engineering construction contractors build sewers, roads, highways, bridges, tunnels, and other projects. Specialty trade contractors perform specialized activities related to construction such as carpentry, painting, plumbing, and electrical work.
The term "construction manager" is used vaguely to define all supervisory-level salaried and self-employed construction managers who direct construction supervisors and workers and manage projects in this fashion. Supervisory level managers work under mid-level and top-level construction managers, who are broadly considered general managers and high level executives
The term "construction manager" is used by the construction industry to represent a company or employee who takes on additional responsibilities and control over the construction projects. A construction manager is like a consultant, and thus provided consulting to the owner or developer related to the progress and logistics of a project
