## About This Quiz

Can you tell the difference between a pipe carrying drinking water and one carrying waste from the tub or toilet? If you're reading a set of blueprints, can you distinguish between a floor drain and a light fixture? If you consider yourself a construction and blueprint reading expert, take our quiz to see how many of these common symbols you recognize!

Constructing a building - even a simple one - is a monumentally complex task. Fortunately, architects, engineers and other designers set a plan before the first brick is laid. Once this plan is committed to writing, the resulting documents provide a step-by-step guide on how the entire project should be constructed.Â

Of course, with all the different elements that go into the average project, there's no way to include details on every sheet of the blueprints. Instead, designers use symbols to represent elements like windows, doors and light fixtures. Builders can then refer to a key or legend to determine what each symbol means -- and many of these symbols are universal, so experienced builders eventually commit them to memory.Â

These symbols tell the builders where to place a tub or toilet, how many windows line each wall, and how the mechanical and electrical components combine to form a functioning system.Â

Think you can identify what these common construction and blueprint symbols mean? Take our quiz to find out!
