This Architectural Drawing is Upper roof structure framing plan layout. A structural framing plan, such as a wall, roof, deck or porch framing plan is a type of plan, usually required by planning authorities for approvals, that shows the configuration of the major structural elements usually made of materials such as timber or aluminium, their sizes and how they come together to hold the structures up. These elements differ in size, and structural engineers usually are able to calculate these sizes based on expected dead and live loads. Structural engineering drawings are easily identified from their mostly line work drawings. Architectural drawings have other features such as room furniture, bathroom and kitchen fixtures in them. Technical identification. For more information and details download the drawing file.
