Two Engineers Reviewing Blueprints and Technical Designs

Close up footage of two people working with blueprints. One person in a blue, checked shirt is writing on the blueprint with a silver pen. Another person wearing a red, checked shirt, is using a yellow pen and a triangle to point out the design on the blueprint. The designs are black and white, technical architectural plans. The engineers are seated at a wooden desk reviewing drafts. This could be used for projects that are about architecture, design, engineering and construction.
