Unit price build-up for a construction estimate

A unit price is only as good as the parts behind it. Instead of typing one number into an estimate line, you can list what one unit of work costs: labor, material, equipment, subcontract and other parts, each with a quantity per unit and a unit cost. Fidrel adds the parts up, shows the price per unit, and keeps the price tied to its build-up until you choose to price the line another way.

Why a single typed unit price falls short

Nobody can see what moved the number

When an estimator types $6.85 per square foot, the reviewer sees a figure and nothing else. If the labor rate changes or the board price jumps, there is no way to tell which part of the price is now wrong without rebuilding it in a side spreadsheet.

The build-up lives in a spreadsheet beside the estimate

Many shops keep the arithmetic in a workbook and paste the result into the estimate. The estimate then carries a bare number, and the workbook that explains it is one email away from being the wrong version.

Overhead sneaks into a unit rate

A unit rate that quietly includes general conditions and profit is hard to compare with the next one, and it gets marked up twice when the estimate adds its own percentages on top.

One unit price, built from four resources

Take a metal stud partition priced per square foot, with figures made up for this page. Labor: 0.07 hours at 58.00 per hour is 4.06. Material, studs, track and fasteners: 1.05 square feet at 1.80 is 1.89. Equipment, a lift: 0.01 days at 90.00 is 0.90. The unit price is 6.85 per square foot. Because every resource has its own description, type, quantity per unit and unit cost, a reviewer who disagrees with the lift can say so on that row. The unit text is yours to write, so square foot, linear foot, each and cubic yard all work, and quantities take up to three decimals while amounts take two.

Direct cost first, markups on top

Keep the build-up to direct cost and let the estimate add the rest. Markups and deductions are calculated in the order shown, each on the direct costs or on the subtotal above it, and Fidrel suggests the names General conditions, Overhead, Contingency and Profit. A markup applies to all items by default, can be excluded for some items and can carry its own percentage for others, so the build-up itself never has to change.

How to build up one unit price in Fidrel

  1. Step 1

    Open the cost item

    Select the cost item in the estimate, make sure Pricing is set to Unit price, and fill in the Quantity and the Unit. While the estimate is open for changes, a Build up the unit price link appears under the price field.

  2. Step 2

    Add a resource for each part

    Choose Build up the unit price and add a resource. Pick its Type, which is Labor, Material, Equipment, Subcontract or Other, write a description, enter the Quantity per unit and its unit, and type the Unit cost.

  3. Step 3

    Read the price per unit

    Each resource shows its own amount, and the foot of the list shows the unit price per unit. The price field no longer takes typing; it says from the build-up and locked, and the item total is Quantity × unit price.

  4. Step 4

    Change it or take it away

    Edit any resource to move the price, or use Remove resource. Pricing the item as a Fixed amount or leaving it Unpriced removes the build-up, and the panel says so before you save.

Locked with the estimate, changed in a revision

The build-up is edited while the estimate is open. When the estimate is approved, the calculation is saved with it, and later changes are made in a revision. Fidrel does its arithmetic in whole cents, rounding each figure once, half away from zero, so the page never shows a number that the saved estimate would change.

What the build-up does not do

Fidrel has no cost database, no assembly library and no labor-rate or productivity table. Every resource is typed by hand, so Fidrel never suggests a quantity per unit or a unit cost, and it does not apply waste factors or labor burden for you. If your labor rate is burdened, type the burdened rate. Pricing the item as a fixed amount or leaving it unpriced removes its build-up. If you want to price a line from a vendor quote instead, remove the build-up first.
