Add freight, recurring location costs and applicable inspection costs to each material unit price; assign delay costs to the activity that absorbs them. That price has to carry the cost of getting the material from the supplier to the place the owner names. When delivery is left as a guess at the end of an estimate, the unit rate drifts away from what you will actually spend. This post walks through adding three delivery cost parts to each material unit price, in the order you would work through them on a real bid. Freight depends on the delivery point; location and inspection costs depend on the supplier, so establish the route before comparing delivered rates.
The three parts are freight to the designated point, recurring costs tied to where the material comes from and where it goes, and the cost of inspecting material when it arrives. They come from the price-related factors in FAR 14.201-8, the federal acquisition rule that describes how an owner weighs delivery when comparing bids. Those rules govern federal purchases. Your state, county, or agency bid documents control your own bid, so treat the federal text as a model of how an owner thinks about delivery, not as a citation for a local job. This guide assumes you already have a quantity takeoff and a supplier list for each material, since the delivery parts are added to those numbers.
Step 1: Pin down who pays for freight and where delivery ends
Start with the solicitation's delivery terms before you open a single supplier quote. The question is where the supplier's price stops and yours begins. The federal text addresses bids made on an "f.o.b. origin" basis, and that label matters because it sets whether transportation to the owner's point is part of the supplier's price or sits outside it.
Read every bid document revision before you finalize freight. A changed delivery point changes the number, and a freight figure built from the original documents can be wrong after a revision. Then, for each material line, write down three things: where the material ships from, the designated delivery point named in the bid documents, and which party the solicitation says takes the freight. Keep the origin and destination on the same line as the item, not in a separate notes tab, so the freight estimate in Step 2 attaches to the right material from the start.
If the documents do not name a delivery point, stop and ask the owner in writing before you price freight. A guessed point means your freight figure may not match the one the owner evaluates, and you will have priced a different job than the one being bid.
Pay attention to who the documents make responsible for unloading. Unloading at the designated point is labor that can sit with the supplier, the owner, or your crew, depending on how the documents read, and whichever party carries it decides which of the delivery parts picks up the cost.
Step 2: Price freight from origin to the designated point
For f.o.b. origin bids, the federal rule requires transportation costs to the designated points to be considered in determining the lowest cost to the Government. For your worksheet, add freight to each item's rate. Keeping freight in the item rate also shows which items are driving the number, which makes the bid easier to defend if questions come back.
Build the figure from a carrier quote for the exact material, the route from origin to the designated point, and the quantity basis the carrier uses. Only then add it to the material cost. A freight number in a different unit from the material will look right on paper and still be wrong on the bid.
Carrier minimums need a decision. If a short order triggers a minimum charge, you can let that order carry the full minimum or spread it across the quantity the minimum covers. Choose one method, apply it to every line that uses the same carrier, and do not switch methods between items to make one unit rate look better than another.
Mixed loads need the same care. When one truck carries several material lines, split its cost across those lines in proportion to what each line takes up on the truck, by weight, length, or piece, and write the split on the worksheet. A single truck cost entered against only one item overstates that item and understates the rest.
Rejected material is its own cost. If an inspection fails a delivery, the return trip and the replacement shipment are not in the original freight quote. Record the return trip and replacement shipment in the freight line for the replacement load.
If a supplier offers delivered pricing, compare that quote with the origin price plus your own freight figure before you choose. The two numbers are only comparable when they cover the same points, so confirm the supplier's delivered price stops at the same designated point the solicitation names.
Step 3: Price the costs and delays that come from location
The second part covers what the location of the supply adds. The federal text lists "foreseeable costs or delays to the Government resulting from such factors as differences in inspection, locations of supplies, and transportation." For your estimate, check how far the supplier is from the site, how the route is served, and how likely the delivery window is to slip.
Put numbers on the costs you can see. A distant supplier can mean more transit days, more trucking for each load, or a partial load that costs more for each unit than a full one. A late delivery can leave a crew waiting, and that standby time belongs in the estimate for the activity that waits, not in the freight line. Tie each delay estimate to the schedule in the bid documents, so you can see which activity absorbs a late shipment and how much time it can absorb. When the delay is uncertain, size the allowance from the schedule time the bid documents actually leave you, not from a general sense of how reliable the supplier seems.
Keep two kinds of location cost apart. Some costs repeat with every delivery, such as the trucking premium for a far site, and they belong in the unit rate for each item shipped. Others happen once with an event, such as a late shipment that idles a crew, and they belong to the activity that absorbs them. Mixing the two makes it hard to tell a recurring cost from a one-time allowance when someone asks how the number was built.
Use the following checks to organize the delivery calculation and the origin review.
The first three rows feed the delivery parts directly. The origin row comes up again in Step 5.
Step 4: Price the inspection differences on arrival
The third part is the cost of checking material when it arrives. Inspection is a real cost that can differ from one source to another. For your estimate the question is practical: does one supplier's material need more handling before it is accepted than another's?
Inspection work that changes cost includes unloading and staging material for a visual check, pulling samples for testing, and waiting for an owner's representative to look at a delivery before the crew can set it. Each of these takes labor and sometimes equipment hours. Estimate handling hours for each check, convert them to the material unit, and add the result to the unit rate only for the items where the check applies. Two suppliers can offer the same product at the same material price and still produce different unit rates, because one arrives ready to install and the other must be sampled on site.
Timing belongs in the inspection estimate too. A check that must happen before installation can hold a crew in place, while a check that fits a normal receiving window costs less because it uses time that is already in the schedule. When the owner performs the check, the cost to you is mostly waiting: the material sits in the staging area and the schedule absorbs the delay. Say so in your estimate rather than burying that time in general labor, because it is a different cost from the handling you control.
Where an inspection happens decides which part of your estimate carries its cost. A check on site lands in your labor and equipment hours, while a check the supplier performs before shipment should show up in the quote you receive. Do not add an inspection allowance to every line by default. A blanket percentage hides which items are actually costly to receive, and it makes the basis harder to show if the owner asks where the number came from.
Step 5: Check origin and foreign-purchase limits before you price around them
Origin is not a freight cost, but the federal text lists it as a price-related factor. That means where a material is made can matter to the bid itself, separate from the delivery math. A low freight number from a foreign source does not settle whether that source can be used on the job.
Treat origin as a gate, not a line item. List the origin of every material, flag each foreign-sourced item, and hold those items out of the delivery calculation until the question is settled. Ask your contracts counsel or the contracting officer whether a foreign-purchase restriction applies to the item under your bid's governing rules, because the answer can change which suppliers you are allowed to use. A rate built on a source you cannot use will not hold up, however carefully the freight was priced.
Origin also affects the freight line itself. A material shipped from a distant port or across a border picks up a different route and carrier than one shipped from a domestic plant. The origin you record in Step 1 should be the actual shipping point, not the supplier's headquarters, so the freight figure starts from the right place.
Step 6: Add the three parts to each unit price and compare on total cost
Now combine the pieces. For each material line, the unit price is the material cost, plus the freight from Step 2, plus the recurring location cost from Step 3, plus the inspection handling cost from Step 4 where it applies. Apply your overhead and profit after the delivery parts are in, so the markup covers the full delivered cost rather than the material alone.
When two suppliers quote the same item, build the full delivered rate for each before you pick one. A supplier with the lower material price can lose once freight, location costs, and inspection hours are added. Unless the bid form asks for the parts separately, enter only the final delivered rate on each line, so the owner sees one number for each item and the breakdown stays in your worksheet.
For multiple awards, compare contract combinations as well as delivered rates. The federal rule has the contracting officer assume "$500" as the administrative cost "for issuing and administering each contract awarded under a solicitation," and it sets individual awards by "the lowest aggregate cost to the Government, including the assumed administrative costs." Use this method to organize the comparison:
- The solicitation divides one material list into two possible awards. You hold a delivered unit price for each item in each award, built with the three parts above.
- You keep the freight and inspection figures as separate columns in your worksheet, so each part of every unit price traces back to its source.
- If the bid is governed by this federal rule, include its assumed administrative cost for every contract in each award combination.
- Compare the combinations rather than choosing the cheapest unit price for each item in isolation.
Other public owners may compare multiple awards differently, so read the award section of your own bid documents before you decide how to split your pricing across suppliers.
Keep the freight quotes, the inspection hour estimates, and the worksheet in the bid file, so each unit rate can be re-checked if the owner asks how it was built.
