Ceiling plans include placement of vents and lighting fixtures.
A ceiling plan is drawn using 1/4-inch-scaled graph paper and is useful to represent ceiling layout and feature information. A ceiling plan indicates the outline of the ceiling perimeters, architectural features and differences in elevation, as well as the sizes and locations of any lighting fixtures, vents, smoke detectors, sprinklers or audio speakers. Such a plan is called a "reflected ceiling plan" because it is drawn as if the ceiling is being viewed in a large mirror placed on the floor below, so that the will have the same directional orientation as the room's floor plan.
Instructions
1. Measure the length of each edge of the ceiling, using the tape measure and ladder. Use the pencil and ruler to draw correspondingly located lines, in scale, on the 1/4-inch graph paper as they would appear if viewed in a large mirror placed on the floor below. In other words, draw the ceiling as though it is semitransparent and being viewed from above. Remember that one foot of length on the ceiling equals one inch on the graph paper.
2. Measure and use the pencil and ruler to draw the dimensions of the outlines of the location of architectural features such as ceiling trays, beams, lighting coves, dormers, moldings and any variations in ceiling height. Number these features on the plan and identify them in a list of correspondingly numbered notes at the bottom of the plan page.
3. Place the 1/4-inch drafting template of square, round and oval shapes on the plan. Choose appropriately sized cutouts to draw the shape, size and location on the plan of any surface-mounted lighting fixtures, electrical outlets, smoke alarms, sprinklers, audio speakers and access panels. Place numbers next to these features on the plan as in Step 2 and identify them in the list of notes at the bottom of the plan.
