SewerOwner

Comparing two proposals

The instinct with a large price gap is to work out who is overcharging. That is usually the wrong question, and it is almost never answerable from the documents.

The answerable question is what each proposal covers. Most gaps turn out to be scope: a different length, a different method, restoration included in one and silent in the other, a permit in one price and not the other.

What this page cannot establish

  • SewerOwner will not tell you which proposal to accept
  • a price difference does not establish that either party is wrong
  • SewerOwner cannot assess workmanship, competence, or reliability
  • a criterion missing from one proposal is not evidence against that contractor

The differences that most often explain a large gap

  • a different length of line — one addresses a section, the other the whole run
  • a different method, with different access and restoration consequences
  • restoration included in one and silent or excluded in the other
  • permits and coordination inside one price and outside the other
  • inspection before or after the work included in one only
  • different assumptions about depth or ground conditions
  • connection work in one scope and not the other

When the comparison genuinely breaks down

Sometimes two proposals cannot be compared, because they rest on different readings of the same evidence — one says a condition is confined to one location, the other says it affects the run.

That is a real technical disagreement, and no comparison tool resolves it. What resolves it is going back to the evidence: what was inspected, how far, and what basis each has for its view of the rest. If that does not settle it, it is one of the few situations where an independent specialist review is proportionate.

What would change the answer

  • both written proposals in full
  • what evidence each references and from what date
  • what length of line each addresses

What to do next

Most large price gaps become explicable as soon as the two documents are set against the same list of scope questions.
