Can six checks reveal a low villa fit-out quotation that leaves out working electrical scope? If you are comparing three bids this week, inconsistent units and supply boundaries can hide sockets, drivers, keypads and testing until they return as variations. Before you compare Riyadh interior design companies before signing, check every bid against the same drawings and award only after the gaps are priced and closed.
Key takeaways
- Have every contractor price the same controlled drawing revisions.
- Count electrical points room by room and define what each point includes.
- Separate lighting outlets from dimming, controls and commissioning.
- Account for omissions before comparing the final contract sums.
The six-pass electrical BOQ audit
- Control the tender documents.
- Build a room point matrix.
- Audit lighting controls.
- Assign supply, installation and testing.
- Normalize the three bids.
- Sign the final clarifications.
What documents must a Riyadh villa electrical BOQ match?
A villa electrical BOQ must match the latest coordinated power, lighting, reflected-ceiling, joinery and control drawings. Check that every bidder used the same room names, schedules, specifications and written scope.
The electrical BOQ must use one controlled tender drawing register
- Record each drawing number, revision, issue date and status.
- List addenda issued after pricing began.
- State which document governs if drawings, schedules and specifications conflict.
- Get written confirmation that the tender set is coordinated for pricing.
The active CIBSE Saudi Arabia electrical design guide covers subjects including small power, lighting, lighting controls, cabling, distribution, earthing and bonding. The publication provides design guidance, not an official Saudi Building Code edition or project approval.
Joinery and reflected-ceiling drawings can reveal omitted electrical points
Check joinery elevations for integrated sockets, appliance feeds, LED strips and drivers. Check ceiling plans for luminaires, sensors, mirror lights, access panels and curtain controls. Add every item to a room-by-room matrix before accepting the BOQ quantity.
A room-by-room point matrix exposes missing sockets, lights and data outlets
A room-by-room point matrix gives all fit-out companies in Riyadh one counting basis. It works only when its quantities come from coordinated drawings and each contractor defines one electrical point in the same way.
What should the Riyadh villa point matrix record?
- Floor, room and device type, including sockets, switched spurs, lighting outlets, data outlets, television points and floor boxes.
- Drawing number, revision, required quantity, BOQ reference, quoted quantity and difference.
- Clarification status and the trade responsible for each excluded item.
Count combined devices carefully. One faceplate may contain several switches, sockets or data modules. Note both the faceplate and its individual devices so contractors cannot count identical work differently.

How should one electrical point be defined in a contractor quotation?
Ask each bidder to state whether a “point,” “item,” “set,” “circuit” or “lot” includes containment, cable, back box, faceplate, termination, labeling and testing. Count circuits and control channels where relevant. One keypad, floor box or joinery outlet can require several power, data or control connections.
Which Riyadh villa rooms need a second count?
- Majlis ceilings with decorative fittings or concealed drivers.
- Kitchens with fixed appliances and under-cabinet lighting.
- Dressing rooms and vanity units with power inside joinery.
- Staircases, landscape areas and home offices with distributed lighting, data or floor boxes.
Use elevations, equipment schedules and ceiling plans for the second count. Do not assume quantities where project records are missing. Next, check whether every lighting point has the required switching and control scope.
Lighting points and lighting controls are separate BOQ obligations
A lighting outlet does not prove that a villa quotation includes working dimming or automation. The BOQ should list switches, dimmers, keypads, sensors, drivers, control modules, panels, programming and commissioning. Exact requirements depend on the luminaires, circuit design, control protocol and approved supplier schedule.
A complete lighting-control BOQ identifies hardware, software and commissioning
Check the control schematic against the panel schedule, module schedule, circuit count and channel count. The price should cover concealed modules, enclosures, gateways, interfaces and required software licenses, not just visible keypads. For lighting scenes, specify who programs them, attends testing, issues commissioning records and trains the owner.

The CIBSE electrical design guide for Saudi Arabia expressly leaves designers responsible for project arrangements and applicable regulatory compliance. Treat the guide as initial guidance, not approval for the villa.
Decorative lighting requires confirmed drivers, access and dimming compatibility
Match each chandelier, LED strip, downlight and decorative fitting to its supplier data sheet. Confirm wattage, driver type and dimming compatibility in writing. Drawings should locate accessible drivers and show the support and connection requirements before the chandelier crate reaches site.
Motorized curtains and smart-home interfaces need named scope boundaries
An interface matrix should assign power, containment, control cable, gateways, final connections, programming and testing to the fit-out contractor or specialist vendor. The next check identifies who supplies, installs and tests each item.
Every electrical BOQ line must state who supplies, installs and tests the work
Each electrical BOQ line should say who handles supply, installation, termination, testing and commissioning. An installation-only price cannot be compared with a complete line item. Separate the duties of the client, fit-out contractor, base-build electrician, joinery contractor and specialist vendors.
Supply-only and installation-only electrical prices are not equivalent
For sockets, keypads and control modules, confirm who provides containment, wiring, back boxes, faceplates, final connections, labels and testing. Owner-supplied devices also need someone assigned to delivery, storage, damage replacement and warranty claims.
Qualifications marked “by others” need a named party. Completion scope should also list test reports, as-built drawings, warranties and operation manuals.
Existing electrical infrastructure must be separated from the new fit-out scope
Distinguish retained wiring from removed and new work. Review the existing-condition survey, distribution-board schedules and available test records before assuming that spare circuits, board capacity or concealed wiring can support the fit-out. Record unknown concealed conditions as an allowance or exclusion, not a verbal assumption.
Normalize electrical omissions before comparing Riyadh fit-out company totals
A fair comparison adds each confirmed omission back to the relevant bid using an agreed tender rate or documented estimate. Compare normalized totals, not headline prices.
What should an electrical BOQ normalization table contain?
Prepare one comparison sheet for all three contractors. Record:
- BOQ reference and point description
- required and quoted quantities
- confirmed omission or qualification
- tender rate or documented estimate
- adjustment and revised total
- written clarification reference
A cheap line may be complete, provisional, installation-only or excluded. Show taxes, attendance, preliminaries, overhead and profit where they affect the adjustment. If no usable rate exists, request a priced clarification rather than inventing one.
Variation clauses determine the cost of points discovered after award
The proposed contract should explain how omitted items, quantity changes and instructed variations are valued. Check document precedence, prior-approval rules, quotation records and any effect on completion time. Flag every adjustment that lacks a quantity, rate or commercial basis, and send contract interpretation to a qualified Saudi construction adviser.

A pre-award electrical reconciliation should end with signed clarifications
Close the reconciliation with a revised BOQ, discrepancy register and signed clarification schedule. The contract should identify accepted drawing revisions, quantities, specifications, responsibilities and the variation mechanism. Keep unresolved items visible as exclusions or provisional allowances.

The owner should not accept verbal answers to electrical scope gaps
Record each discrepancy with its status, responsible party, deadline and resolution. Use clear labels such as “included in revised BOQ,” “excluded from contract sum” or “provisional pending approved design.” Attach the signed schedule to the contract and include it in the document-precedence clause.
What must be closed before the Riyadh villa fit-out contract is signed?
- Point quantities and definitions
- Control scope and supplier schedule
- Switch, socket, driver and control specifications
- Responsibility matrix and exclusions
- Normalized tender comparison
- Variation rules and document precedence
- Outstanding information assigned to a named party and deadline
Have an electrical consultant or quantity surveyor review the reconciliation where needed. Award the fit-out contract only when the final drawing register, revised BOQ and signed clarifications carry matching issue references.
