The questions to ask before you hire an engineering firm.
A checklist of the questions that separate firms that will deliver from firms that will surprise you.
Most engineering firm regret traces back to questions that weren't asked in the first two calls.
By the time you're signing a proposal, the right questions have already been asked. The first one or two calls with a candidate firm are where you separate firms that will deliver from firms that will surprise you. Organize the conversation around the eight themes below, and don't move on until each one has a concrete answer in writing.
Licensure and credentials. Which PE will seal the drawings? What is their license number and state? Is the firm licensed in the project's jurisdiction? Who is the named engineer of record? Are there any disciplines you'll need to subcontract?
Project leadership. Who is the project manager? Who is the lead engineer? Will they personally remain on the job from kickoff through closeout? How many other active projects are they running this quarter? Who is the backup if either steps off?
References and similar projects. What are the last three projects this exact project lead delivered? Can we contact the owner's representative on each? What was the size, jurisdiction, and delivery model? Were any of them rescued from another firm — and why?
Fee structure and change orders. Is this a lump sum, time-and-materials, or not-to-exceed? What triggers a change order? What percentage of recent contract value has come back as change orders? What scope items are explicitly excluded from the base fee?
Schedule and capacity. What is the realistic schedule from notice to proceed through final deliverable? What is the firm's current backlog? Where does our project sit in priority? What dates are the firm willing to commit to in writing?
Insurance and contracting. What are professional liability, general liability, and workers' comp limits? Will the firm name us as additional insured? Are there contract terms — indemnification, limitation of liability, intellectual property — that they will not sign?
Deliverables and acceptance. What exactly is in the final deliverable package? What is the QA/QC process before drawings are sealed? Who reviews calculations? What are the acceptance criteria, and how are disputes resolved?
Communications cadence. Who is our single point of contact? How often are progress updates issued? What is the response time on RFIs during construction? What changes after kickoff if the project lead becomes unavailable?
Get the answers in writing before you negotiate fee. Every firm on EngineerMint comes with pre-verified license data at the source, so the credential portion of this checklist is already done before your first call.

Frequently asked questions
Which questions matter most on small projects?+
Who is the licensed PE of record, what is the fixed fee, what triggers a change order, and what is the deliverable schedule. On a small job those four answers determine 90% of the outcome.
What does a good answer to 'who will lead the project' look like?+
A specific name, that person's PE license number and state, their years leading similar projects, and confirmation they will remain on the job from kickoff through closeout — not a generic 'our senior team will be involved.'
What are the red-flag answers to listen for?+
Vague license claims, refusal to name the project lead, fees materially below market, no clean answer on change-order triggers, and reference projects that don't match yours in size or jurisdiction. Any one of those is a reason to keep shortlisting.
How do I verify a firm's license claims?+
Ask for the PE's license number and state, then check it against the state board's online roster. EngineerMint does this verification automatically on every match — license number, status, discipline, and jurisdiction are confirmed at the source.
What questions get the truth on fees and change orders?+
Ask for the three most recent projects where the firm issued a change order, the reason for each, and the percentage of contract value. Pattern answers reveal scope discipline; one-off answers reveal honesty.
How do I find references the firm hasn't pre-coached?+
Ask for the last three projects the named project lead actually led — not the firm's marketing case studies. Then call the owner's rep on those jobs directly.
When should I walk away mid-conversation?+
When the firm won't put credentials in writing, when fee structure won't be committed to, when the project lead changes between proposal and kickoff, or when references can't be verified. Walking away costs a week; the wrong firm costs the project.
