14 Important Points to Consider in a Floor Plan:
1. Are the grid lines consistent across each floor? The grid numbers on the previous and next floors should match, ensuring that columns align vertically. This consistency is crucial unless there is a special case like column extraction on the top floor.
2. Is the floor elevation clearly marked? For rooms involving water use—such as corridors, porches, bathrooms, toilets, boiling water rooms, and disinfection rooms—are the floors lowered by 0.01 to 0.03 meters compared to adjacent areas? Additionally, are projection lines drawn at thresholds where elevation changes occur?
3. Are the three dimension lines evenly spaced (between 70 to 100 mm)? Is the annotation text uniform in font style and size throughout the plan?
4. Are doors and windows properly numbered? Are doors categorized by their opening size, type of opening, and structural characteristics?
5. Does the outer edge of the column line up with the outer edge of adjacent aisles? After finishing, columns should generally be concealed from the aisle to maintain the required evacuation width.
6. Does the evacuation door open towards the pedestrian flow direction? For doors wider than 1.2 meters, are they divided into sections ranging from 0.6 to 0.9 meters each, especially at entrances?
7. Are stairwell runs clearly indicated? The runs should be shown on the upper half of the first floor, upper half of the middle floors, lower half, and on the top floor with two runs. Is there an elevation mark on the landing? Are the stair dimensions fully detailed in both plan and section views?
8. Is water drainage indicated on the first floor plan and outdoor floor elevations? Are steps or ramps present at entrances and exits? Does the slope of the ramps match the section symbols, reflecting the correct section position and direction? Be sure to carefully compare projections with section diagrams. Is there a compass rose on the first floor plan to indicate building orientation?
9. Are room names annotated using a consistent font and size?
10. Are floor drains installed in rooms with water usage, such as bathrooms? Is the floor slope direction clearly shown? Does the bathroom equipment comply with user capacity requirements? Are separation distances labeled appropriately?
11. The minimum door width in public buildings is 1 meter. Doors serving large areas, heavy user traffic, or equipment access should be designed according to regulations, often requiring sectional openings.
12. Does each floor plan include floor elevations and landing heights? Are canopy elevations also indicated?
13. Are room names clearly and accurately expressed?
14. Are wall sections represented with thickened cut lines, and are columns filled to distinguish them clearly?
