How construction work is priced, planned, checked and recorded in Pakistan. Practical notes for contractors, site engineers and owners - from BOQs and rate analysis to concrete testing and the daily site diary.
Every good construction project starts with a number that can be defended. That number is built from quantities and rates.
A bill of quantities lists every item of work - earthwork, concrete, masonry, finishes - with its quantity, unit and rate. It is the language that measurement, billing and claims all speak.
Unit rates are built from materials, labour and plant, plus overheads and profit. A rate analysis shows how each rate was reached - essential for variations and fair claims.
The full picture - quantities, rates, materials, labour, plant, overheads, contingencies and profit - whether you are budgeting, bidding or setting a house budget. See our BOQ and estimation service.
A realistic contingency covers the cost of changes and the unknown. Too little and you absorb the risk; too much and you lose the bid or overpay the owner.
Estimates only help if you track actual cost against them month by month. Comparing billed work to the estimate shows where money is leaking before it becomes a loss.
Running bills apply the BOQ rates to measured work. When rates are missing, ambiguous or contested, the rate analysis decides the answer. See contractor billing & IPC.
Construction runs on sequences. A good programme protects your time, your money and your claims.
A programme shows each activity, its duration and its order. Simple bar charts work for most buildings; networks and critical path methods suit larger works.
The longest chain of dependent activities sets the finish date. Delay any critical activity and the project slips. Non-critical activities have float - use it, don't waste it.
Foundations before columns, columns before slabs, curing before loading. Getting the sequence wrong causes rework - the most expensive mistake in construction.
Match the programme to labour, plant and materials - and to your cash. A programme that ignores money is a dream, not a plan.
Planned versus actual, updated weekly. Early slippage on a critical activity is caught in days, not at the end of the project.
Delays caused by the client, late drawings, or changes are only recoverable if the programme and records show the impact. This is where EOT claims begin.
Quality is decided by testing, inspecting and recording - not by promises.
Steel tensile tests, cement and aggregate tests, and cube tests for concrete. Test reports are the evidence that what you paid for is what got built.
Mix design, water-cement ratio, slump at placement, cube samples and curing. A 20 megapascal grade designed is only a 20 megapascal structure if the site delivers it.
Key stages - before concreting, before backfilling, before covering works - are inspected first. Missing a hold point means uncovering work later at real cost.
Snag lists catch defects at finishing, not years later. Waterproofing, drainage and finishes are where most quality problems actually surface.
Inspection requests, test results and approved drawings filed in order. At handover, the quality file is what proves the building meets the spec.
Cheap concrete or thin steel saves little and costs the structure. Rejecting bad work early is always cheaper than fixing it later.
Good site management is mostly good record keeping. The diary is the quiet hero of every claim.
Every running bill, EOT claim and dispute is decided on the written record. A site that keeps a clean diary, measures honestly and photographs daily has far stronger billing and far fewer arguments.
Struc-Arch prepares contractor billing & IPC documents and claims & EOT packages from exactly these records.
Common questions about construction practice in Pakistan.
A bill of quantities lists every item of work with its quantity, unit and rate. A cost estimate is the wider calculation of project cost - materials, labour, plant, overheads, contingencies and profit. A priced BOQ is usually the backbone of the estimate.
Rate analysis works out the unit rate of an item by pricing the materials, labour and plant it needs, plus overheads and profit. It matters because BOQ rates are the basis of payment, variations and claims - a fair rate protects both contractor and client.
By testing the ingredients, controlling the mix and water-cement ratio, testing workability at the point of placement, taking cubes for compressive strength testing, and ensuring proper curing. Cube test results prove the concrete delivered matches the grade designed.
The critical path is the longest sequence of dependent activities that sets the project completion date. Delay any activity on the critical path and the whole project is delayed.
A daily diary (weather, labour, plant, materials, work done), measurements, concrete placement records, inspections and tests, instructions from the engineer or client, and photographs. These are the evidence behind running bills, EOT claims and disputes.
