Two offers are comparable only after differences in scope and performance are understood. A cheaper substitute may change design assumptions, installation work, or long-term maintenance.

## What to do
- Create a deviation register linked to the exact specification clause or drawing.- Ask the responsible technical reviewer to accept, reject, or request clarification for each deviation.- Price the impact of missing work and interfaces separately from the quoted total.

## Normalise the assumptions before the price
Create a comparison using the same scope, quantity, service period, and delivery basis. Separate confirmed amounts from estimates and excluded items. Show tax treatment as quoted and ask the appropriate finance reviewer to resolve any uncertainty. Do not invent a cost for a missing item merely to complete the table; request clarification or label the exposure clearly.

Keep the original offers alongside the comparison so another reviewer can trace each figure. The final recommendation should explain material differences in scope and risk, not just show a lowest total. A revised quote should replace the relevant assumptions throughout the comparison.

## Illustrative buying situation
Consider this hypothetical example.

A bidder offers an alternative material at a lower price. The commercial saving cannot be assessed until the engineer understands the effect on performance, dimensions, installation, and maintenance. Put the deviation in a register and obtain a clear technical decision. If accepted, update the comparison for any consequential work. This keeps an apparent price reduction from concealing costs or design changes outside the supplier’s own quotation.

## Your next decision
Make the award recommendation reflect the accepted technical scope and its full delivery cost.
