Material Procurement

Why material procurement is critical

Three forces frame the stakes. Scale: materials are half or more of a project’s direct cost, so a 2% procurement improvement on a $100 million project is a million dollars — found in a process, not in a negotiation.

Volatility: as of early 2026, the US materials producer-price index was up around 6% year-on-year, the sharpest climb since the 2021 spike, with tariff-driven repricing shrinking quote validity from months to days. Individual commodities have moved far more than the aggregate; the specific figures, date-stamped, live on the Procurement Plan page.

And schedule: late material delivery ranks among the top five causes of construction delay in study after study, across regions. The delivery date is a programme date wearing a supplier’s logo, and it is treated as an administrative detail right up until it is the critical path.

Then there is waste. UK research going back to Egan puts material waste at 10% or more per project, with site studies showing actual wastage at roughly double the standard allowances. A meaningful share of that traces to over-ordering and duplicate purchase — which is a procurement-process failure wearing a site failure’s clothes.

The role of procurement discipline in performance

• Requisition discipline — the WhatsApp problem. Construction’s version of maverick spend is the site engineer ordering by phone or WhatsApp: committed cost invisible to finance until the invoice lands, duplicate orders across work fronts, and no specification trail when the wrong item arrives. The fix is not a memo. It is speed. A requisition that checks live inventory first — because the stock may already exist on this site, or on a sister project — and routes to procurement in minutes will beat the phone call. If the formal path is slower than a favour, the favour wins, every time, and no amount of policy changes that.

• Quote comparison means landed cost, never unit price. Unit price is a fraction of the answer. Minimum order quantities, delivery charges, payment terms, quote validity, specification compliance — and on imports, the whole freight-insurance-customs-currency stack. The “cheapest” quote that deviates from specification does not save money; it fails at material inspection and gets re-procured at spot prices, which is the most expensive way to buy anything. So the comparison has to flag the deviation before the purchase order, not after the rejection. And competitive quoting itself is worth real money: procurement research puts hard savings at 3–5% typically, and more where spend was previously fragmented across sites.

• Expediting is a discipline, not a panic. Staged and proactive: chase the order acknowledgement, because an unacknowledged PO is an assumption rather than a commitment. Then pre-production confirmation, production status, pre-shipment, in-transit, delivery. The alternative is expediting-by-panic — discovering at the “where is our switchgear?” stage that the date everybody had been working to was never actually confirmed by anybody.

• GCC imports add a whole logistics layer. Sea freight from China to Jebel Ali typically runs 15–22 days, and 20–28 to Saudi ports. Customs clears in one to three days with clean documents — and documentation errors are the main cause of multi-day blowouts: HS codes, SASO and SABER conformity in Saudi Arabia, ECAS in the UAE. What belongs in the required-on-site calculation is the landed lead time — shipping, plus clearance, plus the road leg — and the vessel and clearance milestones belong in the expediting track alongside production status. These are typical operational ranges rather than official statistics, and they move.

• Consolidation versus urgency is a real tension — name it. Consolidating small requisitions into one order and one delivery saves money on minimum order quantities and delivery charges. It also delays the urgent lines. Urban and Gulf tower sites compound the problem: minimal laydown space, crane-slot offloading, municipal delivery-hour windows. Early over-delivery buys you double handling, damage and theft exposure. Late delivery buys you idle crews. There is no policy that resolves this — only a decision, made per line, against the programme.

What happens without the cycle

A WhatsApp requisition, so the commitment is invisible, so the budget surprise arrives at month end. A skipped acknowledgement, so the delivery date was an assumption, so the slippage is silent until it is premium freight or programme delay.

No inventory check, so the same material is ordered twice, and the surplus becomes dead stock at closeout — feeding the waste statistic that everybody blames on the site.

A unit-price-only comparison, so the minimum order quantity and the delivery charge eat the saving, or the specification deviation surfaces at inspection and the whole thing is bought again at spot.

Each of these failures is boring, small, and entirely survivable on its own. Then you multiply it by the several thousand material lines of a real project.

How Zepth runs material procurement

The cycle is one connected workflow rather than six tools that email each other. Requisitions check live inventory before they become enquiries. Enquiries route to approved vendors with the specification attached. Comparisons are generated from the vendors’ own line pricing, on landed cost, with deviations flagged.

Purchase orders issue with approval controls and post to committed cost immediately. Acknowledgements, expediting milestones and deliveries are all tracked against required-on-site dates — including vessel and clearance milestones on imports. And receipt flows into inventory and into the three-way match.

Nothing is re-keyed between steps. And nothing gets ordered twice because nobody knew it was already on site.
