For small and medium construction firms in Nigeria and across Africa, materials represent up to 60 percent of total project costs. With inflation driving up the prices of cement, iron rods, and finishings, any material leakage directly threatens project margins.
Uncontrolled site issuance leads to costly project delays, cash flow strain, and thin margins. To successfully track materials issued construction site managers must implement a system that balances strict control with daily realities.
Standardise the material requisition process
Every movement of material must begin with a formal written request. Site supervisors should not verbally order cement or steel from the storekeeper or supplier.
Implement a dual-signatory material requisition form. The site engineer must state the specific block, column, or slab where the requested materials will be used.
The storekeeper should only issue materials upon receiving this signed form. This matches material usage to specific phases of the project, making it easier to spot unexplained variations.
Implement tripartite reconciliation
Relying on a single storekeeper to record deliveries and usage creates a high risk of collusion and theft. A robust tracking system uses three independent sources of truth.
First, the supplier delivery note confirms the quantity dispatched from the vendor. Second, the gatekeeper or site security guard must independently count and log every delivery entering the site.
Third, the storekeeper records the materials in the site ledger. Weekly, the project manager must reconcile these three records to identify discrepancies before materials disappear.
Use accessible digital tracking tools
Many construction SMEs fail to track materials because they attempt to use complex enterprise software that site workers find difficult to navigate.
Instead, use simple, mobile-friendly tools that fit existing site workflows. A shared cloud spreadsheet allows storekeepers to update stock levels directly from their phones.
Require site workers to take timestamped photos of delivered and issued materials. Sharing these photos in a dedicated project WhatsApp group creates a transparent, unalterable digital audit trail.
Conduct unannounced physical audits
Systematic tracking is only effective when site workers know the rules are enforced. Regular, unannounced physical counts of high-value inventory are essential.
Focus audits on materials that are easily sold on the open market, such as copper cables, diesel, and cement bags. Compare physical stock against the balance in the ledger.
SME owners should personally conduct or delegate these audits to someone outside the immediate site team. This independent oversight deters internal fraud and keeps records accurate.
To secure your margins today, start by conducting an unannounced physical count of your highest-value materials this week and compare it directly to your gate delivery logs.
