M&A activity snapshot
Land surveying is one of the most fragmented corners of engineering services, and buyers are consolidating it. Census counted 7,288 surveying and mapping establishments employing 58,087 people in 2023. Of those, 4,248 had fewer than five employees, or 58% (Axia arithmetic). That works out to about eight employees per establishment (Axia arithmetic: 58,087 employees across 7,288 establishments).
Deal flow runs on two tracks. Engineering firms buy small boundary, topographic and construction survey practices, mostly to add licensed surveyors. Separately, aerial lidar, photogrammetry and utility-mapping firms trade at platform scale, often between PE sponsors and public consolidators.
The largest recent deal was a merger of a whole engineering group. Acuren completed its combination with NV5 at an enterprise value of approximately $1.7 billion in August 2025 and created a separate Geospatial segment. That segment produced $146.8 million of revenue and $70.7 million of gross profit in the first half of 2026.
This page covers NAICS 541370: boundary and land title surveys, mapping, lidar, photogrammetry and drone survey work. Subsurface utility engineering design sits with engineering firms, and locating lines before digging is a separate support-services code. Civil design firms are covered under Civil & Structural Engineering.
Who is buying
Public engineering consolidators. Bowman Consulting completed seven acquisitions or acqui-hires in 2025 and paid about $75.4 million for them. They included UP Engineering, a Texas civil engineering and surveying firm, and Sierra Overhead Analytics, a precision mapping firm. In 2024 Bowman bought Surdex, a St. Louis lidar and orthoimagery firm.
Testing and inspection strategics. Acuren's CEO cited NV5's engineering and geospatial strengths as a reason for the deal. NV5 had built its geospatial arm by buying Quantum Spatial, which had about 600 employees and was then the largest full-service geospatial provider in North America.
PE-backed geospatial platforms. New Mountain Capital bought a majority stake in SAM, taking out Peak Rock Capital, the majority investor since 2021. SAM employs over 1,800 professionals and is one of the largest nationwide employers of licensed surveyors.
Private multidisciplinary design firms. Atwell bought Manhard Consulting, a nearly 400-person engineering and surveying firm and its largest-ever acquisition. Woolpert bought Dawood, a Harrisburg firm with a staff of over 150 that is a lead engineering and surveying consultant on Pennsylvania Department of Transportation projects.
Drone and technology acquirers. ZenaTech, a Nasdaq-listed drone company, is buying small survey firms to deliver drone services. Its September 2026 purchase of Merritt Paul Land Surveying was its 29th Drone as a Service acquisition.
What buyers look for
Licensed surveyors who will stay. Licensed staff are scarce. The average licensed surveyor is 54, only 14 percent are under 34, and for every three who retire only one new surveyor enters the field. BLS projects about 3,100 openings for surveyors each year, many of them from retirements.
An ownership structure the buyer can hold. State law limits who can own a survey firm. Connecticut requires two-thirds ownership by CT licensed land surveyors for LLCs and professional corporations. In New York design professional corporations, non-professionals may own less than 25 percent of the shares. Bowman's 10-K notes it has formed professional services corporations owned by its founder and other employees to work in states that bar corporate licenses.
Utility and infrastructure clients. Geospatial buyers want recurring work for utilities and government agencies. Acuren tied its Geospatial segment's first-half 2026 growth to state and regional governments and power and utilities clients.
Field crews that cover the client's region. Engineering buyers want survey crews where their land development and transmission clients build. Atwell's Manhard deal added Tennessee and Nevada and strengthened Illinois, Colorado and Texas.
What makes a strong company
A surveying or geospatial firm that commands a premium typically has:
- More than one licensed surveyor in charge, with a successor licensed in each state served.
- An entity and ownership structure that meets each state board's ownership rules.
- Recurring work from utilities, DOTs or repeat developers, not one-off residential boundary jobs.
- Current ALTA/NSPS practice. The 2026 Minimum Standard Detail Requirements took effect February 23, 2026, so commercial title survey templates should already reflect them.
- Owned lidar, drone and GNSS equipment with documented accuracy standards, plus staff to process the data.
- Field technicians paid at market. BLS puts the median surveyor wage at $75,440 in May 2025.
Valuation and deal structure
No public data provider tracks multiples for small survey firms, so the useful benchmarks come from large disclosed geospatial deals. NV5 agreed to pay $303 million for Quantum Spatial, which was expected to generate $30 million of EBITDA on 2019 gross revenue of $128 million. That is about 10.1x EBITDA and 2.4x revenue (Axia arithmetic, using the $303 million price, $30 million EBITDA and $128 million revenue).
The NV5 sale priced in a similar range. Acuren's $1.7 billion enterprise value against NV5's LTM Adjusted EBITDA of $145.6 million is about 11.7x (Axia arithmetic). Baird's fairness opinion compared seven large engineering deals at 10.4x to 15.2x LTM EBITDA, with a 13.0x median. Those comparables are large engineering firms, not survey practices.
Geospatial businesses carry high gross margins. Acuren's Geospatial segment earned 48.2% gross margin in the first half of 2026 (Axia arithmetic: $70.7 million of gross profit on $146.8 million of revenue). Acuren assigned $247.0 million of goodwill to the Geospatial segment.
Seller notes and stock are standard. Bowman paid $43.3 million for Surdex in cash, a promissory note, common stock and assumed liabilities. The note carries 6.50% interest, paid quarterly through July 2027, and the shares had a six-month lock-up. Bowman's 2025 deals used cash and seller notes, including notes convertible into stock.

Outlook
Expect steady consolidation through 2027, led by engineering firms buying licensed surveyors and PE platforms buying utility-focused geospatial firms. Demand drivers are intact. BLS projects surveyor employment to grow 6 percent from 2025 to 2035, and the SAM announcement cites rising utility and infrastructure investment.
Federal lidar funding is the main risk for aerial mapping firms. The USGS 3D Elevation Program's authorization of appropriations expired in FY2024, and the USGS aims to complete a national 3DEP map by 2027. The FY2026 request calls for $3 million from IRA funds for 3DEP. State, local and federal partners already funded 60% of 3DEP data acquisition from FY15 to FY25, so partner budgets matter as much as USGS funding.
