Interior design is “the art or process of designing the interior, often including the exterior, of a room or building.” An interior designer is someone who coordinates and manages such projects. Interior design is a multifaceted profession that includes conceptual development, communicating with the stakeholders of a project and the management and execution of the design.

Architecture is both the process and the product of planning, designing, and constructing buildings and other physical structures. Architectural works, in the material form of buildings, are often perceived as cultural symbols and as works of art. Historical civilizations are often identified with their surviving architectural achievements.

A contractor is assigned to a construction project once the design has been completed by the person or is still in progress. This is done by going through a bidding process with different contractors. The contractor is selected by using one of three common selection methods: low-bid selection, best-value selection, or qualifications-based selection.

Building services engineers are responsible for the design, installation, operation and monitoring of the mechanical, electrical and public health systems required for the safe, comfortable and environmentally friendly operation of modern buildings.

Preconstruction services are used in planning a construction project before the actual construction begins. These services are often referred to as preconstruction or precon. It is a modern practice, considered to be part of construction project management, which is the overall planning, coordination, and control of a project from inception to completion aimed at meeting a client’s requirements in order to produce a functionally and financially viable project.
