What Techniek & Advies Survey does
T&A Survey is a Dutch specialist soil research agency founded in 1992 and headquartered in Amsterdam. The company provides multidisciplinary (water)soil research services spanning explosives/unexploded ordnance detection from WWII, archaeological research, geophysical surveys, environmental assessments, waterbed research, drone-based remote sensing, and geothermal system design. It serves primarily Dutch government entities (municipalities, provinces, water boards, Rijkswaterstaat, Defensie), construction and infrastructure companies (OpenIJ, KWS OCE), and energy and agriculture operators (TenneT, Trias Westland, Royal FloraHolland, Vitens).
The company's technical backbone rests on proprietary hardware and software assets, most notably the TISA 2D and TISA 3D borehole radar systems developed with RvO Innovation Credit funding and TNO subcontractor support, capable of subsurface mapping at depths up to 4,000 meters. Additional proprietary platforms include the Catamadrone (a remotely controlled survey vessel for shallow water mapping), Meetrek (magnetometer frame for waterbed research), Diepe Oppervlaktedetectie (electrode-based deep induction detection), and Inversiesoftware for magnetometer data processing. T&A also operates an integrated drone sensor stack comprising magnetometer, LiDAR, methane gas detection, and corona camera systems, deployed under its T&A Survey Drone Services joint venture with Ursus Airborne. The TISA products are distributed internationally via agents in 14 countries.
T&A generates revenue through project-based professional services contracts priced per scope, with multi-year engagements typical for large infrastructure and municipal programs. The company holds ISO 9001, CS-OOO (full certification for explosive research and detection), WSCS-OCE, CO2-Bewust Level 3, and ROC/ROC-Light drone certifications. Its GTM motion is sales-led, targeting government entities and infrastructure companies through direct engagement, public tenders, and project-based quotations. Beyond Dutch services revenue, the company derives additional value from international product distribution of the TISA line and from certified OOO training programs it has delivered for over 10 years.

Techniek & Advies Survey competitors and assessment
Company assessmentBroad incumbents
- Bureau Veritas: Global TIC company providing testing, inspection, and certification services across infrastructure, energy, and environmental sectors. Comparable to T&A in environmental consulting and site characterization but as part of a broad portfolio, not a UXO/archaeology specialist.
- Fugro: Dutch-headquartered global leader in geophysical surveying, site investigation, and subsurface characterization for offshore, infrastructure, and energy markets. Overlaps T&A across geophysical research, drilling/borehole services, and waterbed surveys, but operates at vastly larger scale and with a broad portfolio.
- SGS: Global testing, inspection, and certification (TIC) giant offering environmental, geotechnical, and infrastructure-related testing services at multinational scale. Overlaps with T&A on industrial/environmental testing dimensions but lacks the specialized UXO/archaeological core.
- Eurofins Environment Testing: Major European network of environmental testing laboratories and consulting services covering soil, water, and contaminants. Overlaps with T&A's environmental research (asbestos, soil contamination) stream at the laboratory/analytical edge.
Regional players
- IDG - Institute for Defence Geophysics: Germany-based provider of UXO detection and geophysical survey services primarily for the German market. Comparable to T&A in subsurface ordnance detection and clearance services, with regional (DACH) rather than Benelux focus.
Direct peers
- Royal Eijkelkamp: Netherlands-based developer and supplier of soil investigation equipment and provider of geotechnical/environmental field research services. Closely comparable to T&A on Dutch soil, waterbed, and geotechnical site investigation work, plus instrument/method development.
- Zetica Geophysical Services: UK-based independent geophysical survey consultancy providing near-surface and UXO-related investigations for infrastructure projects. Comparable to T&A in applying non-intrusive geophysical techniques across transport, utilities, and development sectors.
- SafeLane Global: UK-headquartered specialist in UXO/EO risk mitigation, including pre-research, detection, and clearance services for infrastructure and offshore projects. Comparable to T&A's CS-OOO-style three-phase UXO service model across European markets.
- Deep BV: Dutch firm offering geophysical and geotechnical site investigation services for civil and infrastructure projects. Competes with T&A in subsurface mapping and ground investigation work across the Netherlands.
- Saricon: Dutch specialist in detection of unexploded ordnance (UXO/OOO) and related geophysical surveys for construction and infrastructure projects. Directly competes with T&A in the Dutch explosives pre-research, detection, and approach market with similar CS-OOO-style service offerings.
