Quick Answer
An accurate toilet cubicle Bill of Quantities (BOQ) in Qatar must specify the exact core board type (e.g., 13mm Solid Compact Laminate complying with EN 438-4), hardware alloy grade (Grade 304 vs. Grade 316 stainless steel), mounting system (floor-anchored and headrail-braced), unit of measurement (per complete compartment "Nr" rather than area "m²"), and clear delineations for site laser survey, delivery, and installation.
1. Standard BOQ Structure for Washroom Partitions
In Qatar construction packages, cubicles should be organized under MasterFormat Section 10 21 13 (Toilet Compartments). A complete, dispute-free BOQ item structure should explicitly detail:
- Panel Core Specification: Density (≥ 1,400 kg/m³ for solid phenolic), thickness (12mm or 13mm), and compliance standard (EN 438-4 Type CGS).
- Hardware Schedule: Specific alloy grade (AISI 304 or 316), hinge mechanism (gravity fall or spring-assisted), indicator deadbolt type, and floor pedestal adjustment range.
- Bracing & Wall Mounts: Continuous extruded anodized aluminum box-section headrail and full-height wall channels or angle clips.
- Edge Treatment: Factory CNC-machined radius beveling (no glued edge banding permitted on solid compact laminate).
2. Measurement Conventions: Compartment (Nr) vs. Surface Area (m²)
While older tender formats occasionally quantified partitions by square meters (m²), contemporary Qatar consulting engineers strongly favor unit compartment quantification (Nr). Measuring by unit number ensures that pilasters, door blanks, division panels, hinges, latches, and pedestals are integrated into a single cohesive line rate, preventing measurement discrepancies on corner stalls or end divisions.
3. Representative BOQ Schedule Example
Below is a standard commercial BOQ schedule structure aligned with Qatar tender standards:
| Item | Description | Material Specification | Unit | Quantity |
|---|---|---|---|---|
| 1.0 | Standard Commercial Toilet Cubicle Compartment (Internal dimensions approx 900mm wide x 1500mm deep x 2000mm overall height) | 13mm Solid Compact Laminate (Phenolic Core, EN 438-4) with CNC beveled edges | Nr | Project-Specific |
| 2.0 | Universal Accessible Toilet Cubicle Compartment (Min 1500mm x 1500mm clear space, 900mm clear outward door swing) | 13mm Solid Compact Laminate (Phenolic Core, EN 438-4) | Nr | Project-Specific |
| 3.0 | Urinal Privacy Divider Screen (400mm–450mm wide x 900mm–1000mm high, wall-hung with stainless brackets) | 13mm Solid Compact Laminate or 10mm Toughened Safety Glass | Nr | Project-Specific |
| 4.0 | Standard Ironmongery Set (Gravity self-closing hinges, indicator deadbolt with exterior emergency coin-slot release, coat hook with buffer, and adjustable pedestal feet 100mm–150mm) | AISI Grade 304 Satin Stainless Steel (or Grade 316 for coastal zones) | Set | Project-Specific |
| 5.0 | Overhead Structural Headrail Bracing (Continuous box profile with end wall anchors) | Heavy-gauge extruded architectural anodized aluminum | Lm | Project-Specific |
| 6.0 | Turnkey Site Survey, Delivery & Erection (Including laser setting-out, plumb alignment, and consultant inspection sign-off) | Turnkey Subcontractor Scope | Item | Project-Specific |
4. Critical Scope Exclusions & Inclusions Checklist
To avoid contractor variations during procurement and installation, estimators must clarify the following boundary interfaces:
Typical Scope Inclusions
- Factory CNC cutting, edge beveling & mortising
- Complete ironmongery (hinges, latches, hooks, feet)
- Overhead aluminum headrail & wall channels
- Laser site verification after tiling completion
- Protection film and final hardware calibration
Standard Scope Exclusions
- Wall/floor tiling, screeding & waterproofing
- Sanitary ware (WC pans, flush valves, grab bars)
- Internal timber backing inside drywall cavities
- False ceiling framing and MEP services
- Rubbish skip removal off site (if main contractor scope)
5. Information Required to Obtain a Fixed-Price BOQ Quotation
When submitting a BOQ to Doha Cubicles for pricing, providing the following project data guarantees an itemized submittal within 24–48 hours:
- Architectural washroom plans (CAD .DWG or PDF) with dimensions and door swing directions.
- Elevations or ceiling height confirmation (FFL to false ceiling datum).
- Core panel thickness preference (12mm vs 13mm compact laminate).
- Hardware finish (Grade 304 satin, Grade 316 marine, or black PVD).
- Site location in Qatar and project handover schedule.
