The short answer
Write one schedule per unit type, with one line per opening. Each line needs the room, size, core, slab or prehung, handing, jamb width, hardware function and casing. Then give the count of each unit type. A supplier can quote the whole building from that without guessing.
The columns
| Column | What to write |
|---|---|
| Opening | A number matching the plan, such as D1 to D8 |
| Room | Bedroom 1, bath, linen, coat closet |
| Size | Width × height × thickness, such as 30″ × 80″ × 1-3/8″ |
| Type | Swing, double, bifold, bypass, barn or pocket |
| Core | Hollow or solid |
| Supply | Prehung or slab |
| Handing | Left or right, with the rule you used to read it |
| Jamb width | 4-9/16″ for a 2×4 wall with 1/2″ drywall, or your wall thickness |
| Hardware | Passage, privacy or dummy |
| Casing | Both faces or one face |
Put the choices that are the same for every door above the table: door style, hardware finish, casing and baseboard profile. That keeps each line short.
Worked example: a two-bedroom suite
Style: 2-panel moulded. Finish: satin nickel. Casing DC001, baseboard BB001. Unit count: 16.
| Opening | Room | Size | Type | Core | Hand | Hardware |
|---|---|---|---|---|---|---|
| D1 | Bedroom 1 | 32″ × 80″ | Prehung swing | Solid | RH | Privacy |
| D2 | Bedroom 2 | 30″ × 80″ | Prehung swing | Solid | LH | Privacy |
| D3 | Bath | 30″ × 80″ | Prehung swing | Solid | RH | Privacy |
| D4 | Bed 1 closet | 48″ opening | Bifold | Hollow | n/a | Dummy |
| D5 | Bed 2 closet | 48″ opening | Bypass | Hollow | n/a | Pulls |
| D6 | Linen | 24″ × 80″ | Prehung swing | Hollow | LH | Passage |
| D7 | Coat closet | 28″ × 80″ | Prehung swing | Hollow | RH | Passage |
| D8 | Laundry | 30″ × 80″ | Hollow | n/a | Pocket passage |
All prehung doors in this example use a 4-9/16″ jamb and casing on both faces. Handing is read as hinge side seen from the side the door opens toward.
Mistakes that change the price
- Mirrored suites listed once. A flipped suite flips every hand. List it as its own unit type. See door handing.
- Accessible suites mixed in. They usually take 36″ doors and levers. Give them their own schedule. See interior door sizes in Ontario.
- Suite entry doors included. These are usually fire-rated. We don’t supply fire-rated assemblies, so leave them off our schedule.
- Wall thickness assumed. A 2×6 wall or a double layer of drywall needs a wider jamb. See door jamb width explained.
