By looking at the drawings of a project carefully, one can determine what types of materials are needed to complete the job, as well as understanding which department will be responsible for various parts or aspects of the construction. Additionally, looking at construction drawings helps determine the timeline and sequence of steps – such as when to order certain structural elements – to ensure a safe and successful completion of the job. Furthermore, studying the drawings helps identify any potential risks associated with the project, such as interference from existing structures that may need to be demolished or relocated prior to construction, as well as other hazardous conditions on-site.
