What Streng does

Streng OÜ is an Estonian engineering bureau (Inseneribüroo) founded in 2006 and headquartered at Riia 20-14, Tartu 51010, Estonia. The company is registered as a private limited company (osaühing) under Estonian registration code 11233049 and operates exclusively within the Estonian domestic market with no global footprint claim. It holds three MTR registrations issued by the Estonian Consumer Protection and Technical Regulatory Authority (TTJA) covering Construction Project Expertise (EPE000675), Design (EEP000753), and Construction (EEH001708), giving it licensed standing across the structural design and build value chain. Leadership consists of a single disclosed executive, Oliver Orrin, serving as Board Member and Engineer.

The company's service portfolio comprises four integrated offerings: (1) Konstruktiivne projekteerimine — structural/constructive design of load-bearing and stiffening systems; (2) BIM projekteerimine — 3D Building Information Modeling for project precision and cross-party collaboration; (3) Konstruktiivne konsultatsioon — expert structural consulting; and (4) Projekteerimise projektijuhtimine — design project management from inception to completion. Core technology centers on BIM-based 3D modeling. The firm serves a horizontal range of building categories including public/institutional buildings, commercial and office buildings, industrial facilities, single-family residential homes, apartment buildings, balconies and canopies, infrastructure structures, and stairs and railings.

Revenue is generated on a project-based professional services model with no publicly disclosed pricing, fees, or revenue figures. The go-to-motion relies on direct client engagement combined with a partnership network of seven Estonian architecture and construction firms (Arhitekrum OÜ, Sammas Arhitektuuribüroo OÜ, Arhitektuuribüroo Korrus OÜ, Arhitektuuriklubi OÜ, Tari AS, Innore OÜ, and Makespace OÜ). The firm pursues minimal digital marketing, relying primarily on professional reputation and direct relationships. No investors, funding rounds, subsidiaries, M&A activity, headcount figures, or revenue disclosures are present in the available data, and the company maintains no disclosed social media or application presence.

Broad incumbents

• Ramboll: Global engineering consultancy with a strong building design practice operating across the Nordics. Comparable service lines to Streng but at vastly larger scale and broader geographic footprint.
• WSP: Global engineering professional services firm offering structural and building design as part of a broader portfolio across multiple geographies and sectors, including building and infrastructure work in Northern Europe.
• AECOM: Global engineering and infrastructure consultancy with structural design as a core building service within a much larger portfolio spanning transportation, environment, and construction.
• Arup: Global engineering firm with structural engineering as a foundational discipline and a design-led consultancy culture that resembles Streng's working model, though vastly larger and more diversified across geographies.
• Mott MacDonald: Global engineering consultancy with structural engineering and building design practices serving public and private sector clients with overlapping scope to Streng's segment coverage.
• Egis: Engineering group offering structural and building design services as part of a broader infrastructure and built-environment practice across European markets.
• COWI: Danish-origin engineering consultancy with a strong structural engineering practice and significant Nordic and Baltic footprint. Comparable service model with regional scale Streng lacks.
• AFRY: Nordic engineering consultancy formed from the merger of ÅF and Pöyry, providing structural design and building services across the Nordic region with deep roots in the same geographic market as Streng.
