What Decra does
Decra OÜ is a privately held Estonian engineering consultancy headquartered in Tallinn that provides third-party construction supervision, technical control, and Responsible Welding Coordinator (RWC) services. Its core offering covers four supervisory modalities: construction supervision during repairs, contractor supervision (including expert opinions for judicial proceedings), architectural and construction control against state standards, and monitoring of structural works (foundations, roofs, walls, floors, partitions, finishing). The firm serves private homeowners, construction companies, and housing associations across Estonia, and extends its welding coordination services into Nordic and Scandinavian markets.
The company's technical differentiation rests on specialized expertise in international welding and structural steel standards — specifically EN 1090 (execution classes EXC 1–4) and EN ISO 3834 — which are mandatory for CE marking of construction products sold in the EU. Its engineering team holds International Welding Engineer (IWE/EWE) and PWHT C-level operator qualifications, and the firm issues expert opinions accepted in state construction supervision processes and court proceedings. Supporting services include welding documentation preparation (WPS, WPQR, Welding Log, ITP), non-destructive inspection, and certification preparation, plus ancillary permit and audit services.
Commercially, Decra operates a sales-led, project-based professional services model. Pricing is custom-quoted after initial phone consultation and site visit, with no public rate cards or tiered pricing. The company is distributed through a trilingual website (Estonian, Russian, English), direct phone outreach, and on-site service delivery throughout Estonia. There are no disclosed funding rounds, headcount figures, or revenue data; the firm appears to be founder/owner-operated, banking with LHV in Estonia.
