How To Read Plans
Similar to a map the orientation of the view is downward from above, but unlike a conventional map, a plan is understood to be drawn at a particular vertical position (commonly at about 3 feet above the floor). Objects below this level are seen, objects at this level are shown 'cut' in plan-section, and objects above this vertical position within the structure are omitted or shown dashed. Plan view or "planform" is defined as a vertical orthographic projection of an object on a horizontal plane, like a map.
Typical Index Of A Set Of Plans:
There is no universal standard for sheet order, however the following describes a common approach:
· General Information - The first sheet in a set may include General notes,
Directory of contacts, Engineers in record, scope of work, location of the project, rendering of the project, codes applied and general information.
· Site Plans
Site plans, including a key plan, appear before other plans and on smaller projects may be on the first sheet.
· Landscape Plans
Most projects require a landscape plan, although this can be integrated with the site plan if the drawing remains clear.
· Architectural Plans
Depicting Floor plans, starting with the lowest floor and ending with the roof plan usually appear near the beginning of the set.
· Structural Plans
While smaller projects may only show structural information on the plans and sections, larger projects have separate sheets describing the structure of the building.
Mechanical drawings show plumbing, HVAC diagrams.
· Electrical Plans
These plans Show all related electrical layouts, single electrical lines and outlet locations.
