General contractors
A general contractor is a construction company that bids on a project. The proposal outlines all of the details of a building project, from the materials used to the overall cost. This process takes a lot of time and effort and requires a contractor to prepare a quantity take-off from the project specifications. During the proposal phase, the contractor is also responsible for billing for all materials and equipment needed, overhead costs, and insurance.
Specialised trade contractors
Specialists in building and remodelling activities perform work for a general contractor. As home prices rise, these contractors perform various construction activities for homeowners. Almost three million people worked as specialty trade contractors in the U.S. in 2011. In 2011, there were more than 123,000 recordable injuries, or 4.1 injuries per 100 full-time workers. The average wage for this occupation is around $60,000 per year.
The Specialized Trade Contractors subsectors of the construction industry perform work in specialized areas, such as plumbing, carpentry, electrical work, and building equipment. Some of these contractors work for the general contractor while others work on a subcontract basis. They may also work directly for the property owner. In general, specialty trade contractors perform work on non-residential construction projects as well as new construction.
Civil engineering contractors
A civil engineering company provides integrated engineering and environmental consulting services to clients, including property owners, public agencies, corporations, and institutions. Clients include developers, real estate professionals, and energy companies. In addition to construction sites, the company also provides environmental consulting services. Its projects range from small residential homes to large-scale projects that include the creation of airports.
