Full Editorial Writeup

This is a 16-year-old civil and structural engineering firm out of Houston, focused squarely on infrastructure: roadways, transportation, and bridges. The client base is the kind that pays its bills and keeps coming back: state Departments of Transportation, local municipalities, large general contractors, and developers. A meaningful chunk of revenue is repeat business, which matters when you are buying a professional services firm where relationships are the actual asset.

The numbers tell a clean story. Roughly $5.3M in revenue producing $1.26M in cash flow, a 28% margin, and a five-year upward growth trend. What sets this apart from a typical services broker listing is the visibility: about $3.9M in work-in-progress, $6.5M in backlog (the listing headline rounds to $10M), and a $21M pipeline. That is a lot of contracted and prospective work sitting behind the purchase price.

The firm runs on 50 full-time professionals, including 7 licensed PEs and about 14 EITs. The seller carries no billable hours and has spent the last few years pushing client relationships down to key managers, which is exactly what you want to see before a professional buys a knowledge business. Owner is retiring due to age and is willing to carry 15% and stay for 2-3 years, signaling real conviction in the handoff.

Why we like it

Earnings quality is strong for a services firm: $1.26M cash flow on $5.3M revenue is a 28% margin, and the seller reports no billable hours, meaning the earnings are not a proxy for one person grinding out chargeable work. That is the single hardest thing to find in an engineering acquisition and it de-risks the transition materially.
Revenue visibility is unusually good. You are buying $3.9M of WIP, $6.5M of backlog, and a $21M pipeline against a $4.875M price, so a large share of near-term revenue is already contracted or in motion rather than something you have to go re-win from a cold start.
The end market is genuinely durable. State DOTs, municipalities, and infrastructure spend do not disappear in a recession, and federal and state transportation funding cycles tend to run counter to consumer softness, so the demand base is about as recession-resistant as engineering services get.
The talent moat is real. 7 licensed PEs and ~14 EITs represent years of licensing and DOT qualification that a competitor cannot replicate overnight, and PE stamps are a legal requirement to do the work, so the credentialed bench is the barrier to entry.
Deal structure is buyer-friendly. A retiring owner carrying 15% ($731,250) and committing to a 2-3 year transition shows vested interest in a clean handoff, and that seller note also gives you alignment and downside protection if backlog conversion disappoints.

How to improve it

Lock down the PEs before close. In the first 90 days, put retention agreements and incentive comp in front of the 7 licensed engineers, because the entire value of this business walks out the door if the credentialed staff leave. Model the deal assuming you must pay to keep them.
Build a real business development function. The firm grew on repeat clients and relationships, but the seller was the historical rainmaker; invest in a dedicated BD lead who can pursue the $21M pipeline and net-new DOT pursuits so growth does not stall after the founder exits.
Pursue geographic expansion into the Southeast deliberately. The listing notes a growing presence there, so pick one or two adjacent states, secure the required state PE registrations and DOT prequalifications, and replicate the Texas playbook rather than spreading thin.
Chase federal and government work. State and municipal is the base, but federal infrastructure dollars are flowing; get the firm registered in SAM.gov, pursue the certifications needed for federal pursuits, and add a grants and government contracting specialist to widen the funnel.
Tighten project management and utilization tracking. With 50 staff and a 28% margin, small gains in billable utilization and project write-downs drop straight to the bottom line; implement disciplined WIP and realization reporting to protect and expand margin.
Develop the vertical engineering capability the listing flags. Adding structural work for data centers and large-scale developments diversifies revenue away from pure transportation cyclicality and taps a genuinely hot demand sector where fees are strong.
Formalize succession below the PE level. Convert the ~14 EITs into licensed PEs on a defined timeline so the firm continuously manufactures its own scarce credential rather than having to buy talent in a tight market.

Diligence notes

Verify the backlog and pipeline quality. $6.5M backlog and $21M pipeline are the crux of the valuation, so pull the underlying contracts, confirm which are signed versus prospective, and check historical pipeline-to-revenue conversion rates before trusting the headline numbers.
Stress-test client concentration. A significant portion of revenue is repeat clients and DOT work; get a customer-level revenue breakdown for three years and understand how much depends on any single DOT, contractor, or municipal relationship that could shift.
Confirm the 2026 cash flow figure. The listing cites $1,258,738 as annualized 2026 cash flow, which is a projection, not a completed year; reconcile it to actual trailing-twelve-month financials and tax returns to make sure you are not paying 3.87x on an optimistic forward number.
Scrutinize PE and staff dependence. Map which projects each licensed PE stamps and which relationships they own, then quantify the revenue at risk if any single PE departs; the firm's ability to sign work legally depends on this bench.
Review WIP and receivables aging. Government and municipal clients pay slowly; examine collections history, retainage practices, and any disputes on the $3.9M of WIP to understand true working capital needs post-close.
Confirm the seller transition mechanics. A 2-3 year transition and 15% carry are attractive, but paper exactly what mentorship, client introductions, and non-compete terms are committed, and tie the seller note to backlog and revenue performance where possible.
