An Industry Where Everyone Changes Firms
The architecture, engineering, and construction (AEC) industry employs approximately 7-8 million people in the United States across architecture firms (approximately 110,000 licensed architects and hundreds of thousands of additional design professionals, interns, and support staff), engineering firms (approximately 900,000+ licensed professional engineers across civil, structural, mechanical, electrical, environmental, geotechnical, and other engineering disciplines), construction companies (general contractors, construction managers, specialty contractors, and trade contractors), and AEC industry service providers (building product manufacturers, materials testing laboratories, commissioning agents, and technology vendors).
The AEC industry has a distinctive workforce characteristic that makes email database maintenance particularly challenging: professionals change firms frequently. The average tenure at an architecture or engineering firm is approximately 3-5 years, and senior professionals may change firms multiple times over a career as they seek new project types, geographic markets, leadership opportunities, or firm ownership paths. This mobility is amplified by the project-based nature of the work (professionals may move to a firm that has won a major project in their specialty) and by the industry's boom-and-bust cycle (during downturns, firms lay off staff who then join competitors or start their own firms when the market recovers).
For anyone maintaining a database of AEC industry contacts -- whether an architecture firm tracking its subconsultant roster, an engineering firm maintaining its teaming partner database, a building product manufacturer managing its architect and engineer specification contact list, or a public agency maintaining its RFP distribution list -- this workforce mobility means that email addresses become invalid at a much faster rate than in most other industries. A database of 5,000 architect and engineer contacts can lose 15-25% of its email addresses to firm changes, retirements, and domain changes in a single year.
Principal and Project Manager Contact Validation
The most valuable contacts in an AEC firm database are principals (the firm owners and senior leaders who make hiring decisions, sign contracts, and direct business development strategy) and project managers (the mid-level professionals who manage project teams, coordinate with clients, and make day-to-day decisions about subconsultant selection, product specification, and construction methods). These contacts are also the most likely to change firms or change roles within their current firm.
Principal-level contact decay occurs through retirement (the AEC industry has an aging workforce, with a significant portion of firm principals approaching retirement age), firm mergers and acquisitions (when firms merge, principals may retire, take on different roles, or leave to start new firms), and succession transitions (as founding principals transition ownership to the next generation of firm leaders, the firm's email domain, organizational structure, and key contacts may all change).
Project manager contact decay occurs through promotions (a project manager promoted to associate or principal may get a new title-based email alias), firm changes (project managers frequently move between firms to manage different project types or advance their careers), and project completion (a project manager who was the primary contact during a multi-year project may shift to a different project with a different client and different subconsultant team).
To validate AEC firm contacts, start by exporting your current database of architect, engineer, and project manager contacts as CSV. Upload to Email Extractor to verify email format consistency and identify obvious format errors (mismatched domains, invalid characters, duplicate entries). Then cross-reference against current firm websites and professional directories to verify that each contact still works at the firm listed in your database. For contacts whose firm websites no longer list them, search AIA (American Institute of Architects) member directories, NSPE (National Society of Professional Engineers) member listings, and LinkedIn profiles to locate their current firm and email address.
Multi-Office Firm Deduplication
Many AEC firms operate multiple offices across different cities, states, or countries. A national engineering firm might have 30-50+ offices, each with its own staff, project portfolio, and (sometimes) its own email domain or subdomain. This creates a deduplication challenge because the same firm may appear in your database under multiple office addresses, the same contact may appear under multiple email addresses (a headquarters address and a branch office address), contacts may transfer between offices without notification, and firm acquisitions may result in legacy email domains coexisting with the acquiring firm's domain for months or years during integration.
For example, when AECOM acquired URS Corporation, contacts who previously had URS email addresses gradually migrated to AECOM addresses, but many legacy URS addresses continued to function for an extended transition period. A database that was not actively maintained during this transition could end up with both the old URS address and the new AECOM address for the same person, or with the old URS address that eventually stopped working while the new AECOM address was never captured.
To deduplicate multi-office firm contacts, compile all contact records for each firm (across all office locations and email domains) into a single spreadsheet. Sort by last name and first name to identify potential duplicates. For contacts with multiple email addresses, verify which address is currently active by checking the firm's current office directory pages. Export the deduplicated, verified contact list as CSV. Upload to Email Extractor to perform a final format validation and deduplication pass on the cleaned dataset.
Professional License Cross-Referencing
Licensed professionals in the AEC industry -- registered architects (RA/AIA), professional engineers (PE), licensed landscape architects (RLA/PLA), and certified professionals (LEED AP, CxA, BCPE) -- must maintain active licenses in every state where they practice. State licensing boards maintain public databases of licensed professionals that include the licensee's name, license number, license status (active, inactive, expired, revoked), license expiration date, and (in many states) the licensee's address and firm affiliation.
These licensing board databases serve as a verification source for AEC contact databases because they confirm that a contact claiming to be a licensed architect or engineer actually holds an active license, they provide current address and firm affiliation data that can be compared against your database records to identify contacts who have changed firms, and they identify contacts whose licenses have expired or been revoked (which may indicate retirement, career change, or disciplinary action).
For database verification, cross-reference your architect and engineer contacts against the relevant state licensing board databases. Most states provide online license verification portals where you can search by name, license number, or firm name. For architects, the NCARB (National Council of Architectural Registration Boards) maintains a certificate holder directory that covers architects with NCARB certification (which allows practice in multiple states). For engineers, the NCEES (National Council of Examiners for Engineering and Surveying) maintains records, and each state board has its own verification portal.
