How big is the engineering firm market?

Engineering services is a broad code with many small offices. The Census Bureau counted 63,233 engineering services establishments with paid employees in 2023 (NAICS 541330). California (about 8,900) leads, then Texas (5,800), Florida (5,300), New York (2,500), Colorado (2,400), Virginia (2,300) and Pennsylvania (2,200). The code covers everything from a two-person structural practice to regional offices of national firms, plus industrial and process engineering consultancies. Land surveyors have their own code (541370) and aren't in that count. The Bureau of Labor Statistics counts about 380,600 civil engineer jobs alone. Local firms get much of their work from architects, developers, contractors and public agencies, and principals decide on software, equipment and consultants.

How many engineering firms are there in each state?

California, Texas and Florida have the most. The Census Bureau counted 63,233 establishments in Engineering services (NAICS 541330) across the 50 states and DC in 2023. These are locations with paid employees, so one-person businesses aren't included and the real number of businesses is higher. Use it to size a market before you build the list.

What's in a engineering firm lead list

Every row is one engineering firm business found on Google Maps inside the area you chose, with its email found on its own website and checked against the live mail server. These are the columns that matter most for engineering firms:

Field	Why it matters for engineering firms
category / categories	The main split: civil, structural, mechanical, electrical, environmental and surveying. A drone mapping service sells to civil firms and surveyors; a building energy software vendor sells to MEP firms.
email + grade	Firms publish info@ or a principal's name. Verified means the mailbox exists; Accept-all means the domain takes any address, so treat it as a maybe. Regional offices of large firms usually share one corporate domain.
emails (up to 5, with role and source)	Larger firms list business development, careers and office-specific addresses. The role and source page help you reach a principal or business development lead, not HR.
website (domain)	Group rows by domain. One domain across many offices is a national firm that buys software centrally; a single-office domain is a local firm where the principal decides.
address + distance + in_area	Engineers work regionally, close to their licenses, permits and clients. Area and distance columns let you build a territory list for a rep or a referral network.
linkedin	Most engineering firms keep a LinkedIn company page with team size and project posts. Use it to check the principal's name and the firm's focus before you write.
rating + reviews	Engineering firms get few reviews, so don't filter on them. Residential-facing structural engineers and surveyors are the exception; a lot of reviews there means steady homeowner work.

About 45 columns in all, including up to five emails per business with their role and source, and eight social networks. See a sample export.

Search terms that find every engineering firm

No single keyword finds them all. Businesses file themselves under different Google Maps categories and describe themselves in different words, so a complete list searches every variant across the whole area, then removes duplicates.

Search terms: engineering firm, engineering company, engineering consultant, civil engineer, civil engineering firm, site engineer, structural engineer, structural engineering firm, mep engineer, mechanical engineer, electrical engineer, plumbing engineer, geotechnical engineer, environmental engineer, environmental consultant, traffic engineer, transportation engineering, water resources engineer, fire protection engineer, forensic engineer, land surveyor, surveying company, drainage engineer, septic system designer, foundation engineer, energy engineer.

Google Maps categories: Engineer, Engineering consultant, Civil engineer, Civil engineering company, Structural engineer, Mechanical engineer, Electrical engineer, Environmental consultant, Land surveyor.

Leadraft includes these in its Professional & B2B keyword pack (66 terms), and suggests more in your country's vocabulary when you type a trade.

Who sells to engineering firms, and what works

Engineering and CAD software vendors. Civil design, structural analysis, MEP modeling, project management. Small firms watch license costs and switching risk. Lead with time saved per project and a trial on a live job.
Survey, drone and testing equipment dealers. GNSS receivers, total stations, scanners, drones, field testing gear. Target civil firms and surveyors by territory and offer a demo on their own site.
Subconsultants and outsourcing services. Drafting, BIM modeling, geotechnical testing, permitting. Busy firms subcontract when they're stretched. Send relevant samples and a turnaround time.
Architects, contractors and developers. Firms looking for an engineer for a project can list every structural, civil or MEP firm in the area and request proposals, instead of relying on the first page of search results. See architects and general contractors for the other side.
Professional liability insurance, accounting and recruiting firms. Engineering firms carry professional liability insurance, bill by project and compete for licensed engineers. Offer a renewal review, project accounting help or a candidate pipeline.

How to segment and qualify a engineering firm list

By discipline

Run separate searches for civil, structural, MEP, environmental and surveying terms and tag each row by the term and category that found it. Few vendors sell to all of them with one message.

Local firms vs offices of national firms

Group by website domain. National firms buy centrally, so pitch the corporate team; local firms decide in the office, usually the principal.

Residential-facing engineers

Structural engineers who inspect foundations, septic designers and surveyors serve homeowners and real estate deals. They have more reviews and buy marketing like a local service business.

By territory

Pick a county, draw a polygon or upload a KML territory so the list matches a sales rep's region or a firm's licensing footprint.

Newly opened firms

Engineers often leave a larger firm to open their own practice. A monitor on your area surfaces new firms as they appear on Google Maps, when they're setting up software, insurance and equipment.

How to reach engineering firms

Be precise

Engineers read carefully and dislike vague claims. Say what the product does, what it costs and how it fits their workflow, and back any number with where it came from.

Write to a principal or business development lead

Use the role column. A principal decides on tools and subconsultants; business development handles teaming and referrals. Avoid the HR and careers addresses.

Work around deadlines

Firms work to permit, bid and proposal deadlines. Mid-week mornings tend to work. If they're mid-submittal, follow up in two weeks.

CAN-SPAM and TCPA

Commercial email to businesses is covered by CAN-SPAM: honest subject lines, your physical address and an opt-out that you honor. Calls and texts fall under the TCPA, so call office lines by hand and don't send marketing texts without consent. Read our cold email laws guide and get legal advice for your setup.

How to find engineering firm leads: build the list in four steps

Choose the place. A city, county or ZIP code, a radius around an address, or a shape you draw on the map (or a KML file).
Search every variant. Start from the terms above. Leadraft splits large areas into tiles so you get the businesses past Google's first few hundred results, and keeps only the ones inside your area and in the trade.
Preview before you pay. The free preview shows real businesses already found there, with emails masked.
Export or push. Download CSV or XLSX, or send the Verified emails straight to Instantly, Smartlead, lemlist or HubSpot with your suppression list applied. Each business is charged once, ever.

Engineering firms lead lists: questions

How do I find engineering firm leads?

Pick the city, county or ZIP code you sell into, search the disciplines you want (civil engineer, structural engineer, mep engineer, environmental consultant, land surveyor) and let Leadraft collect every matching firm on Google Maps inside that area. It finds up to 5 emails on each firm's own website and checks every mailbox, so you export only Verified and Accept-all emails.

How many engineering firms are there in the US?

The Census Bureau's County Business Patterns counted 63,233 engineering services establishments with paid employees in 2023 (NAICS 541330). Each establishment is one location, so national firms with many offices count several times, and land surveyors (NAICS 541370) are counted separately.

Can I get a list of only structural or civil engineers?

Yes. Search only that discipline's terms and filter by the category column. Leadraft records each business's Google Maps categories, such as Structural engineer or Civil engineering company. Many firms list several disciplines, so a firm can appear in more than one segment.

Are the emails verified?

Each email is checked against the firm's mail server and graded Verified (the mailbox exists), Accept-all (the server accepts any address, so it's a maybe) or Invalid (never exported). Emails come from the firm's own website, with the page each was found on.

How much does an engineering firm email list cost?

Leadraft charges one business credit per firm, once, and one checked-email credit per verified email you take out. Texas has about 5,800 engineering services establishments with employees (Census 2023). A Texas-wide list fits the Starter plan ($19 a month for 25,000 businesses and 1,000 checked emails); if you want 4,000 verified emails, Growth ($49, 5,000 checked emails) covers it in one month. The Free plan gives you 500 businesses and 50 checked emails a month to test one city first.

Do you include engineers' names or PE license numbers?

No. Leadraft lists businesses, not people, and doesn't pull license records. You get the emails each firm publishes on its own website, often info@ and sometimes a principal's own, with the role and the page it was found on.
