Same BOQ, Different Costs: Why Smart Contractors Plan Their Procurement Early

Imagine two contractors working on similar projects in Lagos. They have the same Bill of Quantities (BOQ), require the same materials, and are working within similar project timelines.

Yet, by the time both projects are completed, one contractor has spent significantly more on materials and logistics than the other.

How is this possible?

The difference may not be in what they are building, but in how they procure the materials needed to build it.

Same BOQ, Different Procurement Decisions

Consider two contractors who need cement, sand, granite, and reinforcement bars for their projects.

The first contractor purchases materials as the need arises. When the site runs low on cement, another order is placed. When the next phase begins, sand and granite are ordered. Each purchase is treated as a separate transaction, often driven by immediate site requirements.

The second contractor takes a different approach. Before work progresses, the contractor reviews the BOQ, identifies upcoming material requirements, plans purchases around the construction schedule, and discusses pricing and delivery arrangements with suppliers in advance.

Where financially practical, this contractor pays upfront or agrees on payment terms that support better pricing. Deliveries are scheduled to match site requirements, and materials with potential supply constraints are identified early.

Both contractors need the same materials. But their purchasing decisions expose them to different costs and risks.

Why A Reactive Contractor May Pay More

1. Every urgent purchase comes with uncertainty.

When materials are purchased only when they are needed, the contractor is exposed to prevailing market prices at each point of purchase. If cement prices rise between orders, the remaining project budget takes the hit.

Without an agreed price-lock arrangement, the contractor has limited protection against subsequent price increases.

2. Frequent deliveries can increase logistics costs.

Ordering materials in smaller quantities or making repeated trips to the site can increase transportation costs per unit. Last-minute deliveries may also attract less favourable rates, depending on availability, distance, and demand.

For materials such as sand and granite, where haulage represents a significant part of the delivered cost, delivery planning can make a meaningful difference.

3. Scarcity leaves little room to negotiate.

When a material becomes difficult to source, contractors who have not planned ahead may have to accept higher prices, wait for availability, or seek alternative suppliers at short notice.

The problem is not simply the price increase. It is having to make purchasing decisions under pressure while the project continues to incur costs.

4. Unplanned procurement creates hidden project costs.

A delayed delivery can leave workers waiting, interrupt scheduled activities, and affect subsequent stages of construction. These costs may not appear on the materials invoice, but they can still affect the project's profitability.

The contractor may believe they are buying materials at competitive prices while losing money through inefficient procurement and delivery arrangements.

The Advantage of Structured Procurement

Structured procurement changes the way contractors approach materials purchasing. Instead of treating every order as a separate decision, it connects purchasing to the entire project plan.

It begins with reviewing the BOQ and construction schedule to understand what materials are required, in what quantities, and when they will be needed.

From there, contractors can take several practical steps:

• Lock in prices early: Where suppliers offer suitable arrangements, agree on prices in advance for planned purchases. Confirm the validity period, payment terms, delivery conditions, and what happens if costs or requirements change.
• Schedule deliveries: Coordinate deliveries with site readiness and construction activities to reduce avoidable trips, storage pressure, and interruptions.
• Plan payments strategically: Where cash flow permits, upfront payment or agreed payment terms may help secure favourable pricing or supply commitments. Compare the benefit against the cost of tying up working capital.
• Anticipate potential shortages: Identify materials that may face seasonal demand, supply constraints, or longer lead times. Explore alternatives and confirm availability before they become urgent requirements.
• Track the budget against actual purchases: Compare planned material costs with actual orders and deliveries to identify price changes, wastage, and emerging cost overruns early.

Structured procurement does not guarantee that every material will be cheaper. Prices may fall after an agreement is made, and storage, financing, or supplier commitments can introduce additional costs. The objective is to make informed purchasing decisions, reduce avoidable expenses, and gain greater control over the project budget.

What This Means for Your Project Budget

The real value of structured procurement goes beyond securing a lower price for a bag of cement or a truckload of granite.

It is about reducing uncertainty across the entire project.

When material prices are agreed in advance, the contractor can plan costs with greater confidence. When deliveries are scheduled, site activities become easier to coordinate. When potential shortages are anticipated, the project is less exposed to emergency purchasing.

This makes it easier to protect margins, manage cash flow, and meet commitments to clients.

For contractors working with fixed-price contracts, where unexpected cost increases can eat directly into profits, that level of control can be particularly valuable.

How MaterialsPro Helps Contractors Procure Smarter

At MaterialsPro, we recognise that builders need more than access to suppliers. They need a more coordinated way to plan and manage the procurement of materials throughout their projects.

Our platform helps contractors source building materials and coordinate deliveries, while our procurement approach supports better planning around pricing, quantities, and timing.

Where agreed arrangements are available, contractors can explore price locks and planned deliveries rather than relying entirely on last-minute purchases.

The objective is simple: help contractors make better procurement decisions, reduce avoidable logistics costs, and gain greater visibility over their materials budgets.

Because the cost of a project is not determined by the BOQ alone. It is also influenced by the decisions made between the day the BOQ is prepared and the day the last material is delivered.

Two contractors can have the same BOQ. The one who plans procurement better may have a better chance of protecting their budget and their profit.
