Building construction is the process of adding structure to real property. The vast majority of building construction projects are small renovations such as addition of a room or renovation of a bathroom. Often the owner of the property acts as laborer paymaster and design team for the entire project. However all building construction projects include some elements in common - design financial and legal considerations. Many projects of varying sizes reach undesirable end results such as structure collapse cost overruns and/or litigation. For this reason those with experience in the field make detailed plans and maintain careful oversight during the project to ensure a positive outcome.
Building construction is procured privately or publicly utilizing various delivery methodologies including hard bid negotiated price traditional management contracting construction management-at-risk design & build and design-build bridging.
Residential construction practices technologies and resources must conform to local building authority regulations and codes of practice. Materials readily available in the area generally dictate the construction materials used (e.g. brick versus stone versus timber). Cost of construction on a per square metre (or per square foot) basis for houses can vary dramatically based on site conditions local regulations economies of scale (custom designed homes are always more expensive to build) and the availability of skilled tradespeople. As residential (as well as all other types of construction and manufactured homes) can generate a lot of waste careful planning again is needed here.
The most popular method of residential construction in the United States is wood framed construction. As efficiency codes have come into effect in recent years new construction technologies and methods have emerged. University Construction Management departments are on the cutting edge of the newest methods of construction intended to improve efficiency performance and reduce construction waste.
