A grey-structure quotation for a 1-kanal DHA Lahore house can look precise while leaving important costs unresolved. A single rate per square foot does not tell you which floors, structural work, services or external works are included. Two apparently similar offers may price different buildings.
The useful starting point is a defined design and a measurable scope. This guide explains how to organise a budget and compare contractors. It does not quote a current Lahore construction rate or promise a fixed total for every 1-kanal home.
Start with the plot documents and the actual design
DHA Lahore’s construction guidance identifies the site plan, drawing approval and demarcation as steps to obtain before construction. Its Building Control checklist also includes soil or geotechnical testing and architectural and structural stability documentation. Confirm the current requirements for your particular property with Building Control before committing to a start date.
Ask your design team for a dated drawing set and a floor-by-floor area schedule. Identify the basement, ground floor, upper floor, stair enclosure and any other proposed structures separately. Plot area and constructed area are different measurements; a contractor should explain exactly which area is being multiplied by the quoted rate.
Have the structural engineer establish the foundation and structural requirements for the site. Do not accept another house’s steel quantities or foundation arrangement as a substitute for your own design.
Define what “grey structure” includes
Treat grey structure as a scope that must be written down, not a package with one universal meaning. Ask every contractor to mark each item as included, excluded or provisional. A provisional item needs an allowance and an agreed way to establish its final cost.
Use this comparison sheet before comparing headline totals:
| Cost heading | What the quotation should clarify |
|---|---|
| Groundworks | Excavation, disposal, filling, compaction and any basement work |
| Structural work | Concrete, reinforcement, formwork and the drawings being priced |
| Walls and plaster | Materials, thicknesses, measured quantities and included surfaces |
| Concealed services | Plumbing lines, drainage and electrical conduits included at this stage |
| External works | Boundary walls, tanks, driveway preparation and site drainage |
| Site running costs | Temporary utilities, storage, security, scaffolding and waste removal |
| Owner-paid items | Design, testing, approvals, connections and items bought separately |
These are questions for pricing, not instructions to adopt a particular construction specification. Your architect and engineer should define the work suitable for the approved design.
Build quantities before comparing rates
Request an itemised bill of quantities, or a sufficiently detailed measurement schedule, from the project team. Each entry should identify the work, unit, quantity, specification and rate. Separate material supply from labour where that helps explain the offer.
For steel, identify the specified grade, sizes and weight basis. For cement, record the product and bag quantity. For concrete and masonry, require the specification used in the estimate. Delivery, unloading, wastage and applicable taxes should be explicitly included or separately priced.
Ask competing contractors to price the same information. If one offer omits external works and another includes them, add the missing scope before deciding which is cheaper. Keep a list of unanswered questions beside the comparison rather than treating blank entries as zero.
Date every quotation and explain price changes
Record each supplier quotation’s date, validity period, delivery location and payment terms. A material price collected several weeks earlier should not be described as today’s purchase cost.
Ask whether the contractor’s offer is fixed for a defined scope or allows adjustments. Where adjustments are proposed, have the agreement identify the affected items, supporting evidence, calculation method and approval process. Obtain appropriate professional advice on the contract wording.
Keep a separate record of design changes. Moving a wall, adding a tank or changing a basement detail can affect quantities even when material prices stay unchanged. Obtain a written description, price and timing effect before authorising additional work, except where urgent protective action is necessary and properly documented.
Keep the budget and payment plan connected
Maintain three figures: the agreed construction scope, separately funded owner expenses, and a contingency appropriate to the uncertainties identified by your team. Avoid adopting a universal contingency percentage without considering design completeness and site conditions.
Tie payment stages to clearly described work and agreed checks. Keep dated photographs, delivery records, measurements and payment receipts. For an overseas owner, appoint a suitably qualified local representative to review progress; photographs alone cannot confirm concealed workmanship or measured quantities.
Review the forecast cost to finish at each stage. Money already paid is not the same as the value of completed work, and a low initial advance does not establish the final cost.
Before requesting proposals, assemble your plot details, drawing revision, area schedule, scope checklist and target programme. Open Guides on Nava Estate for wider property-planning information, or use Contact to explain your phase, plot size and construction stage. Bring the same documents to your architect, engineer and shortlisted contractors so the next conversation produces comparable answers.
