The general contractor is a manager, and possibly a tradesman, employed by the client on the advice of the architect, engineer or the architectural technologist or the client him/herself if acting as the manager. A general contractor is responsible for the overall coordination of a project. A general contractor must first assess the project-specific documents (referred to as bid, proposal or tender documents). In the case of renovations, a site visit is required to get a better understanding of the project. Depending on the project delivery method, the contractor will submit a fixed price proposal or bid, cost plus price or an estimate. The general contractor considers the cost of home office overhead, general conditions, materials and equipment as well as the cost of labor to provide the owner with a price for the project.
Contract documents include drawings, project manual (including general, supplementary and/or special conditions and specifications), addendum or modifications issued prior to proposal/ bidding and prepared by a design professional such as an architect. The general contractor may be the construction manager or construction manager at risk.
A general contractor is responsible for providing all of the material, labor, equipment (such as engineering vehicles and tools) and services necessary for the construction of the project. The general contractor hires specialized subcontractors to perform all or portions of the construction work.
Responsibilities may include applying for building permits, securing the property, providing temporary utilities on site, managing personnel on site, providing site surveying and engineering, disposing or recycling of construction waste, monitoring schedules and cash flows, and maintaining accurate records.
Architectural engineering, also known as building engineering, is the application of engineering principles and technology to building design and construction.
Structural engineering involves the analysis and design of physical objects (buildings, bridges, equipment supports, towers and walls). Those concentrating on buildings are responsible for the structural performance of a large part of the built environment and are, sometimes, informally referred to as "building engineers". Structural engineers require expertise in strength of materials and in the seismic design of structures covered by earthquake engineering. Architectural Engineers sometimes practice structural as one aspect of their designs; the structural discipline when practiced as a specialty works closely with architects and other engineering specialists
Building construction is the process of preparing for and forming buildings and building systems. Construction starts with planning, design, and financing and continues until the structure is ready for occupancy.
Far from being a single activity, large scale construction is a feat of human multitasking. Normally, the job is managed by a project manager, and supervised by a construction manager, design engineer, construction engineer or project architect. For the successful execution of a project, effective planning is essential. Those involved with the design and execution of the infrastructure in question must consider the environmental impact of the job, the successful scheduling, budgeting, construction site safety, availability and transportation of building materials, logistics, inconvenience to the public caused by construction delays and bidding, etc.
