924-937: Is the process of adding structures to areas of land, also known as real property sites. Typically, a project is instigated by or with the owner of the property (who may be an individual or an organisation); occasionally, land may be compulsorily purchased from the owner for public use. Residential construction may be undertaken by individual land-owners ( self-built ), by specialist housebuilders , by property developers , by general contractors , or by providers of public or social housing (e.g.: local authorities, housing associations ). Where local zoning or planning policies allow, mixed-use developments may comprise both residential and non-residential construction (e.g.: retail, leisure, offices, public buildings, etc.). Residential construction practices, technologies , and resources must conform to local building authority's regulations and codes of practice . Materials readily available in

#17327731517371452-581: The "vast majority of large construction projects go over budget and take 20% longer than expected". A construction project is a complex net of construction contracts and other legal obligations, each of which all parties must carefully consider. A contract is the exchange of a set of obligations between two or more parties, and provides structures to manage issues. For example, construction delays can be costly, so construction contracts set out clear expectations and clear paths to manage delays. Poorly drafted contracts can lead to confusion and costly disputes. At
1518-461: The 21st century. Some estimates suggest that 40% of construction projects are now fast-track construction. Broadly, there are three sectors of construction: buildings, infrastructure and industrial: The industry can also be classified into sectors or markets. For example, Engineering News-Record ( ENR ), a US-based construction trade magazine, has compiled and reported data about the size of design and construction contractors. In 2014, it split

On some projects, work on-site will not start until design work is largely complete; on others, some design work may be undertaken concurrently with
1650-413: The Building Cost Index has been issued since 1915. Each index is widely used throughout the U.S. construction industry as a benchmark for measuring inflation. The ENR cost indexes were created in 1921 and overseen for many years by ENR 's director of market surveys, Elsie Eaves. Engineering News-Record publishes quarterly cost reports, which are eight to twelve page collections of articles analyzing

Costs of construction on a per square meter (or per square foot) basis for houses can vary dramatically based on site conditions, access routes, local regulations, economies of scale (custom-designed homes are often more expensive to build) and the availability of skilled tradespeople. Depending upon

For buildings, building engineering is an emerging discipline that attempts to meet this new challenge. Traditionally, design has involved the production of sketches , architectural and engineering drawings , and specifications . Until the late 20th century, drawings were largely hand- drafted ; adoption of computer-aided design (CAD) technologies then improved design productivity, while

The client takes on the contractual role, while the construction or project manager provides the active role of managing the separate trade contracts, and ensuring that they complete all work smoothly and effectively together. This approach is often used to speed up procurement processes, to allow

Like most business sectors, there is also substantial white-collar employment in construction – 681,000 US workers were recorded by the United States Department of Labor as in 'office and administrative support occupations' in May 2021. Large-scale construction requires collaboration across multiple disciplines. A project manager normally manages
2244-750: The data into nine market segments: transportation, petroleum , buildings, power, industrial, water, manufacturing, sewage/waste, telecom , hazardous waste , and a tenth category for other projects. ENR used data on transportation, sewage, hazardous waste and water to rank firms as heavy contractors. The Standard Industrial Classification and the newer North American Industry Classification System classify companies that perform or engage in construction into three subsectors: building construction, heavy and civil engineering construction, and specialty trade contractors. There are also categories for professional services firms (e.g., engineering , architecture , surveying , project management ). Building construction
2310-426: The delivery of services by all businesses, alongside other detailed plans aimed at ensuring legal, timely, on-budget and safe delivery of the specified works. Design, finance, and legal aspects overlap and interrelate. The design must be not only structurally sound and appropriate for the use and location, but must also be financially possible to build, and legal to use. The financial structure must be adequate to build

Depending upon the type of project, a design team may include architects , civil engineers , mechanical engineers , electrical engineers , structural engineers , fire protection engineers , planning consultants , architectural consultants, and archaeological consultants. A 'lead designer' will normally be identified to help coordinate different disciplinary inputs to
2574-821: The design, construction, and maintenance of the physical and naturally built environment , including public works such as roads, bridges, canals, dams, tunnels, airports, water and sewerage systems, pipelines, and railways. Some general contractors have expertise in civil engineering; civil engineering contractors are firms dedicated to work in this sector, and may specialise in particular types of infrastructure. Industrial construction includes offshore construction (mainly of energy installations: oil and gas platforms , wind power ), mining and quarrying , refineries , breweries , distilleries and other processing plants, power stations , steel mills , warehouses and factories . Some construction projects are small renovations or repair jobs, like repainting or fixing leaks, where

In the United States, departments of transportation usually use design-build contracts as a way of progressing projects where states lack the skills or resources, particularly for very large projects. In a construction management arrangement,
3630-435: The project is ready for handover. Design-build became more common from the late 20th century, and involves the client contracting a single entity to provide design and construction. In some cases, the design-build package can also include finding the site, arranging funding and applying for all necessary statutory consents. Typically, the client invites several Design & Build (D&B) contractors to submit proposals to meet
3696-405: The project is started, and ensures that the plan is properly executed over the life of the project. Construction projects can suffer from preventable financial problems. Underbids happen when builders ask for too little money to complete the project. Cash flow problems exist when the present amount of funding cannot cover the current costs for labour and materials; such problems may arise even when
3762-528: The project site. Typically, a construction site will include a secure perimeter to restrict unauthorised access, site access control points, office and welfare accommodation for personnel from the main contractor and other firms involved in the project team, and storage areas for materials, machinery and equipment. According to the McGraw-Hill Dictionary of Architecture and Construction's definition, construction may be said to have started when

Data may be gathered through site analysis , site surveys and geotechnical investigations . Construction normally cannot start until planning permission has been granted, and may require preparatory work to ensure relevant infrastructure has been upgraded before building work can commence. Preparatory works will also include surveys of existing utility lines to avoid damage-causing outages and other hazardous situations. Some legal requirements come from malum in se considerations, or

Some models and policy-making organisations promote the engagement of local labour in construction projects as a means of tackling social exclusion and addressing skill shortages. In the UK, the Joseph Rowntree Foundation reported in 2000 on 25 projects which had aimed to offer training and employment opportunities for locally based school leavers and unemployed people. The Foundation published "a good practice resource book" in this regard at

Use of local labour and local materials were specified for the construction of the Danish Storebaelt bridge , but there were legal issues which were challenged in court and addressed by the European Court of Justice in 1993. The court held that a contract condition requiring use of local labour and local materials was incompatible with EU treaty principles . Later UK guidance noted that social and employment clauses, where used, must be compatible with relevant EU regulation. Employment of local labour
