Selling an engineering or architecture firm: license the project data first, and keep the sale clean

A/E firm M&A in 2026: who is buying engineering and architecture firms

Deal activity is high and increasingly sponsor-backed. Capstone Partners' March 2026 AEC services update counted 361 transactions announced or completed in 2025, up 10.1% from the year before. Private equity was behind 138 of them, 38.3% of the total, up from 22.3% in 2018 (source: Capstone Partners, AEC Services Sector M&A Update (Mar 24, 2026)).

The same update names the kinds of acquirers active in 2025:

• PE-backed platforms adding firms, such as PRIME AE Group's acquisition of Faller, Davis & Associates.
• Sponsors buying platforms outright, such as Kelso & Company and ARA Services Partners' acquisition of Galloway & Company.
• Large strategics, such as WSP Global's purchase of TRC from Warburg Pincus.
• Public serial acquirers, such as Bowman Consulting Group, which completed six deals in 2025.

Each is drawn from Capstone's update (source: Capstone Partners, AEC Services Sector M&A Update (Mar 24, 2026)), and none is connected to Regulr. The fee side is softer for architects: AIA's billings index read 46.6 for July 2026, with billings declining at firms of all specializations (source: AIA, ABI July 2026: Architecture firm billings remain weak (Aug 19, 2026)). For a founder principal with no internal buyer, that combination (active acquirers, weaker billings) is often what starts the conversation about a sale and about other sources of cash.

Engineering firm valuation multiples: what is published

Owners search for engineering firm valuation multiples and architecture firm valuation more than almost anything else about a sale. Here is what Capstone published for 2025 (source: Capstone Partners, AEC Services Sector M&A Update (Mar 24, 2026)):

Read those carefully. Deals with published multiples tend to be large ones, and a 40-person structural or MEP firm is priced on its own earnings, backlog, client concentration and principal dependence. We have not found a published, sourced multiple for small A/E firms that we can cite. Specialist A/E M&A advisors work from private transaction data, and they are the right source for comparables.

Why an acquirer cares about your project archive

In an A/E deal the archive is not a side asset. An acquirer cares about it for at least three reasons, and each one shapes how a data license should be written.

• Professional liability. Claims against design firms can surface years after a project closes, and project files are the firm's record of what it did and why. An acquirer will want to know the files are intact and that nothing in a license limits access to them.
• Reuse. Standards, typical details, firm-built Revit families and past projects of the same type are part of what the acquirer pays for. Under the standard AIA B101 the firm keeps the copyright in its instruments of service (source: AIA Contract Documents, The Rights of an Architect's Instruments of Service), so that library travels with the firm.
• Integration. Platform acquirers usually move a new firm onto their own accounting and project systems. Hosted data that is not exported before the old subscription ends can be lost, which is a risk for the acquirer as much as for you.

A well-written license respects all three: it grants a de-identified copy, leaves the originals and the copyright with the firm, and does not restrict how the firm or its new owner uses its own files.

What a data license is, and is not, in an A/E firm sale

A data license is a contract. The firm grants an AI data buyer the right to use a de-identified copy of specific records, for a stated purpose and term, in exchange for a payment. One buyer program's FAQ puts it plainly: the company keeps its originals and its systems, and the program receives a license to a de-identified copy. A data marketplace says ownership never transfers (source: program terms, Regulr buyer directory).

• You keep the records. Deltek history, models, calcs and the file server stay with the firm and convey to an acquirer as they would without a license.
• It is not equity. No shares change hands, so a license adds no party to the ownership and does not touch an ESOP or a buy-sell agreement.
• It is not a client list. Client and owner names, site addresses and title blocks are masked before delivery.
• It does not move copyright. Under the standard AIA B101 the firm keeps the copyright in its instruments of service (source: AIA Contract Documents, The Rights of an Architect's Instruments of Service), and a training license leaves that in place.
• It is a contract that survives. Exclusivity, confidentiality, deletion and any refresh deliveries bind the firm after you sell it. That is why acquirers read it.

Which engineering and architecture firm records are in scope

Buyers want the record of decisions your people made, linked to outcomes. In a design firm that usually means:

• Proposals and fee estimates with go/no-go and win or loss, from Vantagepoint CRM, BQE Core or Monograph
• Project financials: budgets, hours by phase, earned value, write-offs and utilization, aggregated
• QA/QC checklists, peer-review comments and lessons learned
• Firm-authored design, CAD and BIM standards, typical details and Revit families
• Code analyses and responses to plan-review comments
• Drawings, models, calcs and specs, but only on projects that pass the contract screen

Federal work under FAR 52.227-17 needs the Contracting Officer's written permission (source: 48 CFR 52.227-17, Rights in Data, Special Works (Cornell LII)), and CUI, ITAR and security-sensitive projects stay out. Our guide to who owns architectural drawings and engineering documents covers the project screen, and the engineering and architecture firms guide lists which buyers name the category.

Exclusivity and term: the clauses an acquirer reads first

Exclusivity decides whether the firm, and later its new owner, can license the same records again. Program terms vary (source: program terms, Regulr buyer directory):

• One buyer program licenses to its AI customer on an exclusive basis, and the seller agrees not to license the same data for external AI training for 24 months.
• One buyer program structures its licenses as exclusive by default.
• One buyer program's published closed deals are each a perpetual exclusive license.
• Other programs publish no exclusivity terms, so ask before you compare offers.

Two A/E details make exclusivity harder to promise. Firms on Newforma Konekt's 2023 terms granted Newforma a perpetual license to customer data that includes AI training (source: Newforma Konekt terms (updated June 26, 2023), §9.3), and a platform acquirer may already have its own plans for the archive. A narrow, project-listed, time-limited exclusive is easier for an acquirer to accept than an open-ended one.

License before the LOI, or after

Timing changes who decides and who gets paid.

• Before the LOI. The firm and its current owners decide the scope and receive the payment. The license is disclosed as an existing contract. This is the cleanest order.
• Between LOI and closing. Most LOIs and purchase agreements restrict new contracts outside the ordinary course, so a license usually needs the acquirer's consent and becomes part of the negotiation.
• After closing. The records belong to the company under its new owner, and whether to license them is the new owner's decision.

Where the payment goes at closing is set by the purchase agreement. Installments still due after closing need to be addressed in the deal documents. This page does not give tax or deal-structure advice; your M&A advisor and accountant handle that.

Internal ownership transitions, mergers and wind-downs

Many A/E firms change hands internally: principals sell to the next generation of partners, or to an employee ownership plan. A license fits those transitions the same way it fits an outside sale. The firm licenses a copy, the records stay, and the internal buyers inherit any exclusivity, so they should see the terms before they sign.

For a firm that is merging into a larger one or winding down, the clock matters more. Hosted software stops being yours to export soon after the contract ends: Deltek's SaaS terms provide Customer Data only on a written request made within 30 days of termination (source: Deltek SaaS Terms V20261009 (ST12.2)). Export first, then cancel. Some programs accept closed firms: one broker that names engineering takes firms with 20+ staff at peak, and a buyer program for industrial engineering records accepts companies no longer trading (source: program terms, Regulr buyer directory). Our guide to Deltek, Autodesk, Newforma and Bluebeam data terms lists each export window.

What acquirers will ask about a data license

Expect an acquirer of an A/E firm to ask for:

• The license itself. Counterparty type, scope, term, exclusivity, permitted uses and any refresh deliveries.
• The project screen. Which projects were included, which agreement forms they used, and how federal, CUI and work-for-hire projects were excluded.
• De-identification. How client names, site addresses, title blocks, seals and staff names were removed, and who checked the sample.
• Third-party content. Evidence that subconsultants' sheets, contractors' RFIs, manufacturer content and master-spec base text were excluded.
• Professional liability. Whether any included project is subject to a claim, and whether the firm's insurer was informed if the policy requires it.
• Money and obligations. Amounts received and still due, warranties you gave about the records, deletion confirmations, and any clawback or indemnity.

Checklist: licensing A/E firm data before a sale

1. Inventory your systems: Deltek or BQE, Revit and CAD archives, Newforma, Bluebeam, file servers, Microsoft 365.
2. Export hosted data while subscriptions are active, and record what each export covers.
3. Build the project list and sort it by agreement form, client type and federal status.
4. Start the scope with the firm's own records: proposals, financials, QA/QC, standards.
5. Collect offers from more than one buyer on the same scope, and compare exclusivity as closely as price.
6. Ask each buyer to state in writing how the license treats a sale of the firm.
7. Approve the scope yourself, audit the de-identified sample, and keep the deletion confirmation.
8. Sign before the LOI if you can, and list the license in your disclosure materials either way.
