Engineering: a guide for pros

What customers ask, how to win the job, and what to put on your profile.

Offering engineering

You apply engineering to design and evaluate buildings, utilities, drainage and mechanical or electrical systems, and you prepare documents that support permits and construction. Clients rely on you for sound calculations, clear scope and reports they can act on.

What customers ask

Are you licensed for this type of work in this state?
What will your report or drawings include, and will they carry your stamp?
What will you test or measure on site?
How many revisions are included?
Who handles the permit submittal and the review comments?
What is excluded from the scope?

How to win the job

On the first call, ask for the problem, the site, the documents, the permit path and the schedule, then say which discipline covers the work
Visit the site and record the measurements, the test results and the photos before you propose a design
Write the deliverables in the proposal as a list, such as drawings, calculations, a report and a stamped letter, so the scope is clear
State the testing you will do and what it adds to the scope, so the client can decide
Offer construction review visits and say how their findings are reported back to you
Explain the revision terms and what a change in scope triggers

What to put on your profile

List the disciplines you practice and the types of projects you handle
Post examples of site assessments and designs, with personal and client details removed
Show the states where you are licensed and the agencies whose review you are familiar with
State the testing equipment and the site methods you use

Follow-up that helps the customer

Offer a follow-up site review after construction to confirm the work matches the design
Suggest a maintenance check on the system after its first season of use
Offer to keep the calculations, the drawings and the reports on file for future reference

Licenses and permits

Engineers are commonly required to be licensed where they practice and where they stamp documents, and the right to stamp is usually restricted. Check with your state licensing board for your license, continuing education and stamping rules, and confirm the local building department accepts your stamp for the work.

Questions

How do I handle a client who wants a stamp on work I did not design?

Decline to stamp work you did not design or review. Offer a review of the existing design with the limits of the review written out, or refer the client to the engineer of record.

How do I limit liability on an assessment of an existing system?

State exactly what was examined, what was tested and what was not accessible. Put those limits in the report and in the scope, so the findings are read in the right context.
