Virtual Construction or VC consists of the virtual equivalents of the actual building parts and pieces used to build a building. These elements have all the characteristics - both physical and logical - of their real counterparts. These intelligent elements are the digital prototype of the physical building elements such as walls, columns, windows, doors, stairs etc., that allow us to simulate the building and understand its behavior in a computer environment way before the actual construction starts.
General Contractor or GC manages and hires sub-contractors while acting as a primary contact with construction clients. They are employed for overall co-ordination of project and to achieve better, faster and cheaper quality of work. Depending on the project delivery method, the general contractor submits a fixed price or cost plus price proposal.
