Read the survey with your designer

Ask your designer to show how the survey relates to the site plan. A survey does not answer every planning, utility or ground-condition question.

  • Confirm the property and survey date.
  • Identify features, levels and access relevant to the design.
  • Refer boundary uncertainty to the appropriate professional.

Ask what each report covers

A report can contain conditions and recommendations that affect the work. Ask its author which findings apply to the current home design.

  • Check the location and extent of investigation.
  • Identify design recommendations that appear in the drawings.
  • List any additional review or investigation still needed.

Turn unresolved findings into bid questions

Do not let competing contractors quietly assume different site conditions. Ask for a written explanation of what each bid includes and how unknown work will be handled.

  • Identify excavation and disposal assumptions.
  • Clarify retaining walls, drainage and access work.
  • Ask who prices a change if the site differs from the assumed condition.

What to check next

  • Confirm report dates and scope.
  • Discuss recommendations with the design team.
  • List unresolved conditions.
  • Issue identical site information to bidders.
