Why the cheapest bid costs the most in the long run
Three contractors price the same civil scope three different ways. The unit rates matter, but they do not show what delay, corrective work, or weak planning will cost over the full project.
A low number is easy to compare. Civil work is harder. Weather changes, field conditions do not match the plans, later trades affect completed work, and the project still has to reach closeout.
Cost is a function of time
On a project that runs for years, the bid is only the opening line. Schedule recovery, corrective work, compliance issues, change orders, and remobilization all affect the final cost.
Kevin Smith describes it as cost as a function of time. We may not carry the lowest unit or hourly rate. The value has to be measured against production, quality, schedule, and the amount of corrective work required later.
How to dig past the number
If you only compare the bottom line, you may be relying on the most optimistic estimate. Instead, evaluate the contractor behind the bid:
- Time horizon of their past work. Ask how their jobs looked one, two, three years later. Durability is the part you can't see at handover.
- Quality record. On civil and solar work, that means the compliance trail: DEQ reports, erosion and sediment control, corrective actions (or the absence of them).
- Capacity to actually man the job. A price means nothing if the crew to back it isn't there. Ask who's running it and how many other jobs they're running at the same time.
- How they handle a field problem. Ask who diagnoses it, who can make the decision, and how quickly the recovery plan reaches the crew.
A low unit price does not show the cost of delay, corrective work, or missed production.
Where the savings actually come from
The savings that do not appear in a unit rate come from constructability review, sequencing, coordination, and field decisions made before a problem becomes expensive. Jason McConnell's version is simpler: moving dirt with a pencil is cheaper than moving it with yellow iron.
When three bids land on the table, compare the time horizon of the work alongside the unit price. Ask how the contractor plans, responds, documents, and closes out a project.
