Construction - choose a jigsaw puzzle to solve

Construction is the process of constructing a building or infrastructure . Construction differs from manufacturing in that manufacturing typically involves mass production of similar items without a designated purchaser, while construction typically takes place on location for a known client. Construction as an industry comprises six to nine percent of the gross domestic product of developed countries . Construction starts with planning, design , and financing; it continues until the project is built and ready for use. Large-scale construction requires collaboration across multiple disciplines. A project manager normally manages the job , and a construction manager, design engineer , construction engineer or architect supervises it. Those involved with the design and execution must consider zoning requirements, environmental impact of the job , scheduling, budgeting, construction-site safety , availability and transportation of building materials, logistics , inconvenience to the public caused by construction delays and bidding. Large construction projects are sometimes referred to as megaprojects.
