Joinery, doors & windows in a Niger bill of quantities
In Niger, the joinery section of a Bill of Quantities (Devis Quantitatif Estimatif) (Devis Quantitatif Estimatif (DQE) / DPGF) is measured to DQE / DPGF (French practice). It covers 6 principal groups of work — door frames, linings and door leaves through to staircases and balustrades — and is headed in the bill as "LOT 3 — JOINERY, DOORS & WINDOWS".
Joinery, doors & windows is one of the sections every Bill of Quantities (Devis Quantitatif Estimatif) (Devis Quantitatif Estimatif (DQE) / DPGF) in Niger is built from. This page sets out what belongs in it, the unit each item is measured in under DQE / DPGF (French practice), the local conventions that change the quantities here, and a worked example for a 150 m² house — plus the errors in this section that actually cost money on site.
What this section covers
- Door frames, linings and door leaves
- Window frames and glazing
- Ironmongery — hinges, locks, handles, closers
- Fitted kitchen units and worktops
- Built-in wardrobes and shelving
- Staircases and balustrades
How each item is measured
| Item | Unit | Measurement rule |
|---|---|---|
| Doors and frames | no. | Enumerated by type, stating size, material, finish and handing. Priced against a door schedule, not a count. |
| Windows | no. or m² | Enumerated by type or measured on the opening area, stating glazing and opening arrangement. |
| Ironmongery | no. or set | Enumerated per door, by set. Easily 10–15% of the joinery section on a house. |
| Kitchen units | no. or m | Enumerated by unit type, or measured on the run length, stating the specification. |
| Staircase | item | A single lump sum item, fully described — flights, landings, balustrade and finish. |
Local conventions in Niger
- —Standard door size here is 900 × 2100 mm; standard window 1500 × 1200 mm, with bathroom windows around 600 × 600 mm.
- —A house of typical size here carries roughly one door per 12 m² and one window per 14 m² of floor area — a useful check against the schedule.
- —Non-standard sizes are made to order and cost disproportionately more than the size difference suggests.

What goes wrong in this section
- —Ironmongery is specified vaguely and priced cheaply, then upgraded on site at full retail. Schedule it properly at bill stage.
- —Joinery lead times routinely exceed the masonry programme. A late frame order holds up plastering and therefore everything after it.
- —Enumerate from a schedule, never from an area rule, whenever a drawing exists — this is the one section where estimating from floor area is indefensible.
