Plumbing & electrical services in a Haiti bill of quantities
In Haiti, the services 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 — incoming water supply, storage and distribution pipework through to lighting points, socket outlets, switches and fittings — and is headed in the bill as "LOT 3 — PLUMBING & ELECTRICAL SERVICES".
Plumbing & electrical services is one of the sections every Bill of Quantities (Devis Quantitatif Estimatif) (Devis Quantitatif Estimatif (DQE) / DPGF) in Haiti 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
- Incoming water supply, storage and distribution pipework
- Sanitary fittings — WCs, basins, showers, baths, sinks
- Soil, waste and vent pipework
- Below-ground foul drainage, manholes and the point of disposal
- Electrical supply, distribution board, circuits and earthing
- Lighting points, socket outlets, switches and fittings
How each item is measured
| Item | Unit | Measurement rule |
|---|---|---|
| Pipework | m | Measured on the centre line along the run, stating diameter and material. Fittings are usually deemed included. |
| Sanitary fittings | no. | Enumerated by type, fully described including taps and traps. |
| Drainage | m | Measured on the run, stating diameter, bedding and average depth. Excavation is measured with it. |
| Manholes | no. | Enumerated by depth band, fully described. |
| Points (lighting / power) | no. | Enumerated per point, with the rate deemed to include the cable back to the board. |
| Distribution board | item | A single item stating the number of ways and protective devices. |
Local conventions in Haiti
- —Services intensity here is taken at about 0.12 lighting points and 0.18 socket outlets per m² of floor area.
- —A typical dwelling carries 2 WCs, 2 basins, 1 shower and 1 kitchen sink.
- —There is no general municipal sewer here, so a septic tank and soakaway must be measured, built and inspected. It is a substantial item and the one first-time builders most often leave out entirely.
Worked example — 150 m² house in Haiti
Quantities for this section on a representative single-storey house, computed from Haiti construction conventions. Rates are deliberately not shown: they move constantly and are priced against your own drawings.
| Description | Qty | Unit |
|---|---|---|
Doors ~1 per 12 m² of floor area | 13 | no. |
Windows ~1 per 14 m² of floor area | 11 | no. |
Lighting points 0.12/m² | 18 | no. |
Socket outlets 0.18/m² | 27 | no. |
WC suites Typical fixture count per dwelling | 2 | no. |
Wash hand basins Typical fixture count per dwelling | 2 | no. |
Septic tank & soakaway Municipal sewer is not generally available; on-site treatment assumed | 1 | item |
What goes wrong in this section
- —Services are measured as points, but priced as systems. A bill with 40 'lighting points' and no distribution board, cable sizing or earthing description cannot be priced reliably.
- —Below-ground drainage carries its own excavation, bedding and backfill. Measuring only the pipe understates the item several times over.
- —Fittings 'PC sum' items get chosen late and expensively. Fix the specification at bill stage or accept the variation.

What goes into the services section of a bill of quantities in Haiti?
+
Incoming water supply, storage and distribution pipework; Sanitary fittings — WCs, basins, showers, baths, sinks; Soil, waste and vent pipework; Below-ground foul drainage, manholes and the point of disposal; and 2 further groups of work. Under DQE / DPGF each is described, measured in its own unit, and priced separately so the total is auditable line by line.
What units is plumbing & electrical services measured in?
+
Pipework in m, Sanitary fittings in no., Drainage in m, Manholes in no.. Getting the unit right matters more than getting the quantity precisely right — a contractor can adjust a quantity, but cannot price an item measured in the wrong unit at all.
How is plumbing & electrical services different in Haiti from elsewhere?
+
Services intensity here is taken at about 0.12 lighting points and 0.18 socket outlets per m² of floor area.
What is the most common costly mistake in this section?
+
Services are measured as points, but priced as systems. A bill with 40 'lighting points' and no distribution board, cable sizing or earthing description cannot be priced reliably.
How do I get this section measured for my own project?
+
Upload your dimensioned drawings to Enormous Buildings. The bill is produced in the DQE / DPGF format, grouped by section with plumbing & electrical services priced in HTG (G), and every unit rate carries a source so a Haiti quantity surveyor can check it.
