Most structural engineering quotes lose the job before the client has finished reading them. Not because the fee is too high. Because the quote arrived four days after the enquiry, looked like it was copied from a Word document from three years ago, had no expiry date, and nobody followed up.
Speed, format, and follow-through matter more than most structural engineers think. The technical quality of your work wins repeat clients. The quality of your quoting process wins new ones.
The five mistakes in most structural engineering quotes
First: taking too long to respond. An architect sends an enquiry on Monday. They've probably sent the same enquiry to two or three structural engineers. A Harvard Business Review study on lead response times found that firms responding within an hour were seven times more likely to have a meaningful conversation than those responding 24 hours later. For structural engineering enquiries the window is longer, but the principle holds. A three-day delay is a three-day head start you've given a competitor.
Second: inconsistent format. If different engineers in your firm quote differently, with different fee structures, different assumptions, different levels of detail, then every quote is a custom document created from scratch. That takes time. It also means the same client, comparing quotes from your firm across two jobs, is comparing different things.
Third: missing scope definition. The most expensive quotes are the ones that win on low fees and lose money during delivery. Unclear scope leads to scope creep. Scope creep leads to either writing off time or having a difficult conversation about a fee variation the client wasn't expecting. A quote that clearly defines what's in and what's out protects both parties.
Fourth: no follow-up. Most firms send a fee proposal and wait. If the client doesn't respond in a week, maybe a nudge email. If they don't respond to that, the enquiry is quietly shelved. But according to the National Sales Executive Association, 80% of sales require five or more follow-up contacts. Most engineers do one or two. The enquiries that feel like they've gone cold often haven't. They've just been deprioritised by a client who is busy.
Fifth: no expiry date. A quote without an expiry date is a promise you've made indefinitely. Material costs change. Your capacity changes. A quote accepted four months after you sent it, at a time when you're already at full capacity, is a problem you created. Thirty days is the standard for most residential and light commercial work.
What a strong structural engineering quote includes
The scope definition: what structural work is covered, what isn't, which RIBA work stages you're responsible for. If building control submissions are included, say so explicitly. If they're not, say that too.
The deliverables: a specific list of what the client receives. Structural calculations. Drawings. Building control submission documents. Reports. Being explicit here manages expectations and gives you a reference point if a scope dispute arises later.
The fee breakdown and payment terms: what the total fee is, how it's structured, when payments are due. 'On completion' is not a payment schedule. Stage, amount, and date. The IStructE guidance on professional fees and appointments is clear on the importance of detailed fee schedules in structural engineering appointments.
The assumptions and exclusions: the conditions under which the quoted fee applies. If the site visit reveals unexpected complexity, you need a line in the quote that covers that. If the fee assumes a single revision cycle, say so. Assumptions you leave unstated become disputes you have to manage later.
The follow-up problem
The mechanics of following up are simple. The barrier is time. Sending a manual follow-up email three days after a proposal, then again a week later if there's no response, requires you to track it. Across fifteen active enquiries, that's an administrative task in itself.
Automated follow-up sequences solve this without removing the personal element. You write the sequence once. 'Following up on the fee proposal for the Elm Street extension, happy to discuss if you have any questions.' The system sends it at day 3. A different version at day 7. You stay in front of the enquiry without thinking about it.
The Association for Consultancy and Engineering's 2023 fee benchmarking study found that engineering consultancies with structured quoting processes had measurably higher conversion rates than those handling enquiries ad hoc. That's not a coincidence. It's the difference between having a process and improvising one.
What this looks like in practice
One Uncle handles the full quoting process: automated quote generation using your firm's standard templates, milestone-linked fee structures, automatic follow-up sequences at day 3 and day 7, and a record of every enquiry from first contact through to project. The quote lives in the enquiry record, which becomes the project record when the client accepts.
You built a practice that does good engineering. Winning more work from the enquiries you're already receiving shouldn't require more effort. It requires a better process.
