Pricing Materials and Equipment

Why Pricing Accuracy Matters

A quantity takeoff tells you how much of something you need. Pricing tells you what it costs. Errors at this stage ripple through the entire estimate: an understated material price can erase your profit margin before a single shovel hits the ground. Accurate pricing requires at least two independent sources—a published cost database and a current vendor or rental quote—so you can cross-check data and apply local market conditions.

Published Cost Data: RSMeans

RSMeans (published by Gordian) is the most widely used published cost reference in US commercial construction. It lists material, labor, and equipment costs organized by CSI MasterFormat division. Each line item shows:

• Material unit cost – the bare cost of the material per unit (e.g., per LF, SF, CY, EA)
• Labor unit cost – the cost to install one unit, based on standard crew productivity
• Equipment unit cost – the cost of equipment allocated to one unit of production
• Total bare cost – the sum of those three components
• O&P (overhead and profit) – typically shown as a percentage added to arrive at a contractor's price

RSMeans data is national average pricing. It includes a City Cost Index (CCI) that lets you adjust national figures to a specific metro area. To apply it, multiply the national bare cost by the local CCI factor (expressed as a decimal, e.g., 0.94 for a lower-cost market, 1.18 for a high-cost city). Always note the RSMeans edition year, because material prices change annually.

Vendor Quotes

A vendor or supplier quote is a written price offer from a material supplier for a defined quantity and specification. Quotes reflect actual current local market prices, including freight, fuel surcharges, and regional shortages or surpluses. Key rules for working with vendor quotes:

1. Match the specification exactly. A quote for 8-inch standard concrete masonry units (CMU) is not interchangeable with a quote for 8-inch lightweight CMU.

2. Record the unit. Lumber prices may be quoted per board foot, per linear foot, or per piece. Concrete block is typically quoted per unit. Confusion about units is a leading cause of pricing errors.

3. Note the validity period. Quotes often expire in 30 days or less. Flag the date on your pricing worksheet.

4. Confirm delivery terms. A price that does not include delivery ("ex-works" or "pickup only") must have freight added before it enters your estimate.

When your vendor quote and RSMeans diverge by more than roughly 10–15%, investigate why. Local market conditions, specification differences, or a minimum-order premium are common reasons.

Reconciling Two Sources

Document both prices side by side. If you use the vendor quote as your primary price (because it is current and local), show the RSMeans figure as a check. If the quote seems unusually low, do not use it without confirming the supplier understands the full specification—a price that is too good is often wrong.

Equipment Cost: Two Methods

Rental Rate Method

The simplest approach: obtain a daily, weekly, or monthly rental rate from a local rental company or a published rental rate guide. Add operating costs—fuel, lubricants, operator labor (if not already in crew labor), and minor consumables. Divide or multiply to match the duration needed for the task.

Daily equipment cost = Rental rate + Fuel/day + Consumables/day

This method works well for short-duration tasks and equipment you would not own.

Ownership-Plus-Operating (O+O) Cost Method

When a contractor owns equipment, the cost per unit of time includes:

• Ownership costs: depreciation, interest on investment, insurance, taxes, and storage. These accrue whether the machine works or sits idle.
• Operating costs: fuel, lubricants, tires or undercarriage wear, filters, and routine maintenance. These accrue only when the machine runs.

Simplified formula often used in estimating:

Hourly ownership cost ≈ (Purchase price − Salvage value) ÷ Useful life in hours

Total hourly equipment cost = Hourly ownership cost + Hourly operating cost

For estimating purposes, many published guides (including RSMeans equipment cost tables) provide an all-in hourly or daily rate for common machines that blends both components. Use those published rates when you do not have the contractor's actual ownership data.

Extending Quantities to Cost

Once you have a unit price from your chosen source, extension is straightforward:

Extended cost = Quantity × Unit price

Carry your units through every step. If your takeoff shows 48 CY of concrete and your price is per CY, the extension is direct. If your takeoff is in SF of formwork and your price is per SF, again direct. Mismatched units are the most common arithmetic error in cost summaries.

Build a pricing worksheet with columns for: item description, CSI code, quantity, unit, source (RSMeans or vendor), unit price, and extended cost. Subtotal by CSI division before rolling up to the project total.

Safety Considerations

Pricing work often involves site visits to verify quantities or meet with suppliers. On any active construction site, wear the minimum required PPE: hard hat, safety-toed boots, and high-visibility vest. Follow all site-specific safety orientation requirements. If you are near equipment operating areas, maintain the distances posted on barricades and never stand in an equipment swing radius. Estimators who visit sites with excavation must be aware of OSHA excavation hazard rules—stay back from open trench edges and observe any shoring or sloping in place. Never enter a confined space for any estimating purpose without proper confined-space entry procedures in place.
