Construction is defined as any work for building, repair, renovation, refurbishment or alteration of immovable property such as a home or an industrial building. Not just erection, but also disassembling and decommissioning of property, are included under the industry called construction.

Construction is a delicate process that involves several pieces of equipment and materials and, of course, financial investment. The type of equipment needed depends on the kind of work to be undertaken and the terrain involved. Cranes, forklifts, tractors, bulldozers, plows, skid-steer loaders, mini excavators, scrapers, etc. are some of the equipments used in construction. Depending on the nature of the job, construction may be light or heavy, and hence the equipment would also differ.

Before undertaking any major construction work, the necessary permits and licenses are required from the municipal authorities. Major construction companies already possess their licenses that are issued by the governments of state. People wishing to have construction work done approach construction companies. These companies provide their expertise, labor, equipment and avow to complete the job within a fixed period of time. Delay in completion of job may oblige them to pay compensation.

The entire process of construction is legally bound by a contract signed between the person owning the property and the company carrying out the construction job on it. Some construction companies provide their expertise, but hire labor and machines from other companies. This is called as sub-contracting. All liabilities of sub-contracting lie with the companies signing the sub-contract and not with the party hiring the company.

Construction jobs also include repair and maintenance work of public utilities like freeways, flyovers, railway system, etc. These works are contracted by the construction company with the state governments and the most important clauses in them are quality and time. Procrastination in such jobs leads to public inconvenience that reflects poorly on the company apart from obliging them to pay penalties.

The construction industry is today a multibillion-dollar industry in the US. Several major companies have been in this field for decades. They have built up severe reputations and have also brought about innovations in their jobs by using newer and newer technologies and machinery.
