The term "builder" can be applied to a large group of professionals associated with the construction of buildings (residential, industrial or commercial) and infrastructure (power lines, pipelines, roads, railways, bridges, airfields and tunnels).
Each construction project involves a unique team of people to plan, design and carry out the work. The construction of a residential building, for example, requires the participation of a construction manager, design engineer, construction engineer and project architect. Effective planning is essential if a project is to be executed successfully. Those involved in the design and construction of infrastructure must take the following aspects into account: environmental impact, scheduling, budget, construction site safety, the availability and transportation of building materials, logistics, inconvenience to the public caused by construction etc.
