What SIEBERT+TALAS does

SIEBERT + TALAŠ is a privately held architecture and engineering firm founded in 2003 in Bratislava, Slovakia, registered as a limited liability company (spol. s r.o.) with a separately registered branch in Prague, Czech Republic. The firm employs approximately 72 architects, engineers and BIM specialists across its two offices and has delivered projects spanning more than 3,000,000 square meters across at least nine countries. Its operations are organized around four integrated service lines — architecture, traffic and infrastructure, BIM services, and advisory — serving enterprise and government clients in commercial, residential, hospitality, retail, transportation, aviation, healthcare, public-sector and urban-planning segments.

The firm's technical foundation is a BIM-first methodology built on ArchiCAD as the primary authoring platform, with multiplatform coordination through the open IFC (Industry Foundation Classes) format to interoperate with Revit, Allplan, Tekla, Solibri and other industry tools. This model-based approach supports 3D-coordinated documentation, spatial clash detection, real-time change propagation across linked information sets, and facility-management model delivery throughout the building lifecycle. Revenue is generated on a project-commission basis through direct enterprise engagement, international architectural competition wins (e.g., the IPD competition for Einsteinova Business Center), and government procurement for PPP technical advisory.

The firm holds EN ISO 9001:2016 certification across the S+T GROUP, Czech Civil Aviation Authority certification for airport ground-facility design, and project-level sustainability credentials (BREEAM Communities Excellent and the first WELL Building Standard certification in Slovakia, both for the Nivy Station project). It has developed specialized PPP advisory expertise on Central European highway concessions (D4, R1, R7) and Greek regional airports (with the Aetos consortium). Repeat enterprise clients include HB Reavis, IPD International Property Development, Development 4, Slovenská sporiteľňa and SPP, with government clients including the Ministries of Transport of Slovakia and the Czech Republic.

Direct peers

• Populous: Global architecture practice specializing in large-scale venues, transport and urban regeneration projects with a similar masterplanning and infrastructure orientation — relevant for benchmarking on large footprint commissions.
• Chapman Taylor: UK-headquartered international architecture practice with similar scale and a comparable mix of large-scale commercial, retail, residential and transport projects across Europe and Asia — directly comparable in scope, geography and project size band.
• Benoy: International architecture and masterplanning firm of comparable scale with a strong portfolio in retail, transport and mixed-use projects. Already a documented project partner with S+T on Stanica Nivy — directly comparable in offering, project types and client base.
• Broadway Malyan: International architecture, urbanism and design practice of comparable size with strong European and emerging-market presence across mixed-use, residential, hospitality and masterplanning — closely aligned in offering and project typologies.
• BDP (Building Design Partnership): Multidisciplinary architecture and engineering practice with strong credentials in transport, infrastructure, healthcare and public buildings. Already a documented project collaborator with S+T on Stanica Nivy — comparable in integrated architecture-plus-engineering model.
• John McAslan + Partners: International architecture practice with comparable size, heritage-led renovation expertise (relevant to S+T's SLSP SNP branch reconstruction) and a portfolio of cultural, transport and masterplanning projects across Europe.
• Allies and Morrison: UK architecture practice of comparable size with deep expertise in urban regeneration, residential and public architecture — closely comparable in scale, typology mix and heritage-sensitive renovation work.

Broad incumbents

• Aedas: Global architecture firm with extensive European and Asian practice across mixed-use, transport and commercial projects. Significantly larger than S+T but operates in overlapping sectors — relevant as a broader incumbent competitor for international bids.
• Foster + Partners: Iconic global architecture firm with extensive European infrastructure, commercial and masterplanning work. Larger and brand-dominant — relevant as a broader incumbent setting the benchmark S+T competes against for high-profile commissions.
• BIG (Bjarke Ingels Group): Global architecture and design firm with high-profile European mixed-use and infrastructure projects. Larger and more brand-visible, but competes for the same category of large-scale, sustainability-led commissions that S+T targets.
