In large construction projects, such as this skyscraper in Melbourne, cranes are essential. In the fields of architecture and civil engineering, construction is a process that consists of the building or assembling of infrastructure.[citation needed] 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 su
pervised by a construction manager, design engineer, construction engineer or project architect. For the successful ex*****on of a project, effective planning is essential. Those involved with the design and ex*****on of the infrastructure in question must consider the environmental impact of the job, the successful scheduling, budgeting, construction site safety, availability of building materials, logistics, inconvenience to the public caused by construction delays and bidding, etc
