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.
Various specialists are involved in the construction process, the most common being bricklayers, carpenters, iron and steel workers, electricians, glaziers, plasterers, heavy equipment operators, heating and cooling experts, landscapers, painters and decorators, roofers, stonemasons, tilers and waterproofing specialists.
Construction activities require the consumption of resources (energy and materials) and generate waste and atmospheric emissions — all of which have significant environmental impacts. The overall impact of the built environment on human health and the natural world can be minimised by:
The concept of green building (also known as green construction or sustainable building) entails environmental responsibility and resource efficiency throughout the life-cycle of a building — from siting and design to construction, operation, maintenance, renovation and demolition. This requires close cooperation between the design team, architects, engineers and clients at all stages of a project. The practice of green building expands on and complements the traditional focus in the construction industry on economy, utility, durability and comfort.
New technologies are constantly being developed to ensure greener buildings, with the common objective of achieving designs that reduce the overall impact of the built environment on human health and the natural world. Measures to achieve this include:
