Which professionals may your new home need?

Know which person can answer a design, site or construction question without having to coordinate every discipline yourself.

Start with the design team already appointed

Ask your architect or lead designer to explain the current team, the scope of each appointment and any work not covered. Different properties need different expertise.

  • Identify who coordinates design revisions.
  • Check whether structural and site design appointments cover the present scope.
  • Record who answers contractor questions during bidding.

Match the specialist to the question

A surveyor, geotechnical engineer and civil engineer address different subjects. Ask the lead designer which specialist needs to confirm a particular issue.

  • Survey: property measurements and related survey records.
  • Geotechnical: ground investigation and recommendations within the report’s scope.
  • Civil: grading, drainage and site-service design within the appointment.

Be clear about any construction consultant’s role

An owner may want independent help with bid comparisons, project records or site observations. Agree that service in writing and distinguish it from the contractor’s and design team’s duties.

  • Define the questions the consultant will help answer.
  • Clarify who can approve changes or authorize work.
  • Confirm fees, deliverables and any limits to site review.

What to check next

  • List appointed professionals.
  • Identify gaps in the appointments.
  • Agree who coordinates questions.
  • Record approval authority.
