Under project architecture and civil engineering, construction means building or assembly of any infrastructure on a site or sites. Though this may be thought of as a single activity, in fact construction is a feat of multitasking. Normally the job is managed by the construction manager, supervised by the project director, design engineer or project architect. While these people work in offices, every construction project requires a large number of laborers, carpenters, and other skilled tradesmen to complete the physical job of construction.
For the successful execution of a project functional planning is essential. Those concerned with the design and execution of the infrastructure in question must consider the environmental impact of the job, the unbeaten scheduling, budgeting, site safety, availability of materials, logistics, inconvenience to the public caused by construction delays, preparing tender documents, etc.
