Construction Site Cost Control Checklist for Contractors

Cost control on a construction site is mostly a matter of routine. The same twenty checks, done weekly, catch most problems while they are small. This checklist is written for contractors in Nepal and applies to a house builder as much as a larger civil contractor. Adapt it to your contracts and tick what applies.

Before work starts on a site

1. BOQ loaded with item numbers, units, quantities and rates.
2. Cost budget prepared for each major item.
3. Store set up with a named storekeeper or supervisor.
4. Petty cash float agreed and a voucher book issued.
5. Labour rates agreed and written down.
6. Subcontractor work orders signed with scope, rate and payment terms.

Every day

7. Attendance marked before work starts.
8. Materials received are checked against the challan and recorded.
9. Materials issued to work are recorded with the item they were used for.
10. Expenses entered with bill photo and cost head.

Every week

11. Wage sheet signed by workers and reconciled with the muster.
12. Work measured and entered against BOQ items.
13. Stock counted at the store and compared to the book balance.
14. Petty cash float checked: cash plus vouchers equals the float.
15. Progress and spending compared for each major item.

Every month

16. Running bill prepared, checked and submitted.
17. Subcontractor ledgers reconciled and payments approved.
18. Client payments received are matched to bills and pending amounts listed.
19. Cost to complete estimated and compared with remaining contract value.
20. Variations reviewed and billed or followed up.
21. Supplier ledgers checked and VAT invoices collected.

A walkthrough of one week on a generic site

Take a house under construction in a Kathmandu valley municipality. On Sunday the supervisor marks attendance for a mason gang, helpers and a bar bender. Cement and rod arrive; the storekeeper checks the quantity against the challan and records the receipt. On Tuesday columns are poured and the engineer records the measurement and the cement used. On Thursday the supervisor submits petty cash vouchers and the office refills the float. On Friday the wage sheet is prepared from the muster, advances are deducted and workers sign. The engineer compares the week's cement use with the volume poured and notices consumption is higher than expected, so on Saturday he checks for wastage and for deliveries with short quantity. None of this is clever. Each step is small, and together they keep the numbers believable.

Warning signs and responses

Sign	Likely cause	Response
Material use higher than work done	Wastage, theft or poor mix control	Count stock, supervise mixing, check deliveries
Wages rising faster than progress	Low productivity or inflated muster	Check attendance and task allocation
Bills delayed by the client	Incomplete measurement sign-off	Resolve measurement queries first
Subcontractor advance larger than work done	Over-advancing	Hold payment until measured

Price the next job with what you learned

The biggest long-term benefit of cost control is better tendering. When you know what concrete, brickwork and plaster really cost you per unit on past jobs, including wastage and labour productivity, you can quote future work with confidence. Keep a small library of actual unit costs from finished projects, updated with current material rates. Contractors who rely on remembered rates tend to underprice complicated jobs and overprice simple ones. Contractors who use their own actuals win a healthier mix of work.

At the end of each project, hold a short review: what went over budget, what went under, what was learned and what to do differently. Write three lines and file them with the project. After ten projects, that file is worth more than any textbook.

Keep documents where people can find them

Drawings, approved variations, test reports and correspondence should be filed per project. If the engineer changes, the new person must be able to continue without a long handover. A shared folder or document system helps; ours is described at document management software.

Handover and defects period

Costs do not stop when the building is finished. Keep a list of snag items raised by the client at handover, the date each was fixed and the cost incurred. Hold retention amounts on your own register with the date they become due, and put a reminder in the calendar for each release. Many contractors lose money simply because a retention release date passed unnoticed. Close each project formally: final measurement, final bill, supplier and subcontractor settlements, return of unused materials to the store and a last cost summary comparing the budget with the actual result.

Safety and statutory records

Site safety, insurance of workers and building permit conditions are important, and they are handled under rules from the municipality and other authorities. Keep copies of permits and inspection notes with the project file and check requirements with the relevant office. Software stores your records but does not replace compliance.

Make the checklist a habit

Print it, pin it in the site office and give one person the job of confirming each item. Review it for five minutes in a weekly team meeting. After a month you will know which items are routinely skipped, and those are the ones to fix first.
