There are many different types of construction company. Not all contractors specialise in the same fields and not all companies do the same construction work. Depending on the type of work they do, construction companies can be classified into the following eight types:
1. General contractors
A general contractor provides all of the labour, equipment, materials and services needed for the construction of the project. General contractors often hire subcontractors to perform part or all of the construction work on a project – especially those subcontractors that are specialists in their field, such as plumbers, electricians and roof tilers.
An owner-builder takes responsibility for domestic building work done on their own land. They are legally responsible for the project from beginning to end. Owner-builders construct buildings for themselves, to sell once it is finished or to rent out and manage. Many owner-builders also act as general contractors as a secondary business.
3. Small renovation contractor
Small renovation contracts usually work on jobs with small budgets or that don’t require large amounts of capital. They do work that does not need a lot of estimations or require a large construction organisation. They usually do home renovations and alterations, as well as small commercial and office work. They often have their offices at home and do their paperwork in the evenings.
4. Real estate developer
A real estate developer is a type of owner-builder who constructs property developments for personal ownership. However, they also build to sell before or after finishing a project. This category includes one- and two-family home builders. Most real estate developers will buy an empty plot of land and construct several independent homes for maximum resale value.
5. Package builders
Package builders both design and construct buildings. Their services often include buying the land as well as financing the project. Package builders can usually show prospective clients examples of similar buildings they have completed for previous clients. They often employ their own architects and engineers, as well as construction workers.
6. Professional construction manager
A professional construction manager is an individual or company who does all the required work on a building project, on behalf of or as an agent of an owner. The construction manager often supplies all the necessary personnel required. The management company outsources the construction work in the name of the owner and does all the necessary administration, supervision, safety regulation, requisitioning, paying of subcontractors, payroll reports and other work on the owner’s behalf, for a fee.
7. Sponsor builder
Sponsor builders often work in the field of government-aided or subsidised building, particularly in the housing sector. A sponsor-builder may be responsible for the planning design, construction, rental, management and maintenance of a project. A sponsor steers a project through the government processing and design stages. They also hire attorneys to deal with the various financial institutions, government agencies and real estate consultants.
8. Program manager
Sometimes, general contractors or construction managers broaden their services by offering program management. These services can include the demolition of existing buildings on the site, the acquisition of a new site, providing financial analyses of new buildings and the hiring of an architect on behalf of the owner. A program manager will also supervise all services, advertise for and receive bids from contractors for the new work, obtain tenants and help administer and manage the entire project.
These eight construction companies have various fields of expertise and specialise in different aspects of construction. When building a structure, it is important to first find the correct construction company for your needs and requirements, based on the services they offer and what type of company they are.
