37 Million Blueprints Are Printed Every Year. Before construction begins on a job site, blueprints will be printed and re-printed numerous times over by architects, project managers, building owners, engineers and contractors. Our local repographics shop gets an average of 35 print requests a day from this crowd.
That person holding the blueprints on a building site? That's a construction manager. Construction managers, also known as general contractors or project managers, oversee and allocate resources for any number of construction projects, from houses and buildings to bridges and skyscrapers.
