Separate removal from the new build
Ask for demolition and disposal to be identified separately. Check whether the quote includes removing old posts and disposing of excavated material, as well as taking away the existing wall.
Look at how the job is accessed
Ask where materials will be delivered and whether the quote allows for moving them from the street. Ask how the plan changes if equipment cannot reach the wall.
Identify provisional items
Ask which costs are firm and which are allowances. For any allowance, ask what it assumes, what might change it and how a revised cost would be approved.
