What .Bieker does

.bieker AG is a Frankfurt-headquartered architecture and general-planning practice founded in 2003, delivering single-source HOAI-based mandates (Leistungsphasen 1–9) across data centers, offices, retail, education, public-sector buildings and existing-building revitalization. Its core offering bundles architecture, interior, structural, MEP, fire protection, building physics, infrastructure, funding advisory, DGNB auditing and BIM management under one contractual roof, supplemented by a four-partner cooperation network (Robert C. Spies, INVISCO tec, Ingenieurbüro Poindecker, F+P Facility and Process) for MEP, electrical and building automation scopes. The firm's flagship specialty is data center general planning aligned to DIN EN 50600, with 30+ delivered campuses — including a 77.4 MW Frankfurt campus, a 70.4 MW Hattersheim campus and a 60.5 MW Rüsselsheim campus — and named references such as maincubes, Deutsche Bahn, DLR, REHAU, Deutsche Börse, Tommy Hilfiger, Heraeus, Jobcenter Frankfurt-Höchst and Stadt Babenhausen.

Underlying technology is BIM-first: 3D BIM coordination with clash detection, issue management, Common Data Environment and digital model handover, supported by a buildingSMART- and BIM Professional-certified team that develops custom Revit Add-ins using RevitAPI and Python. An internal "biekiwiki" knowledge base underpins the firm's ISO 9001:2015-certified quality management across three legal entities (.bieker Holding GmbH, .bieker AG, .bieker kontinental). The firm operates from Frankfurt (HQ), Budapest (.bieker kontinental Kft., the CEE delivery hub) and a newly opened Dublin studio led by Managing Director Dualta Jones, with 55+ experts.

Revenue mechanics are entirely project-based professional services billed per HOAI Leistungsphasen on multi-year commissions, acquired through direct enterprise and public-sector sales by named senior contacts (Tobias Euler, Susanne Hansmann, Máté Kovács, Stefanie Boßmeyer, Dualta Jones, Anke Thestorf), supported by industry events, a content-heavy own-website portfolio and channel partners. No public price list exists; all engagements are quote-based. The firm is privately held (no funding rounds, no acquisitions, no IPO), ISO 9001:2015-certified, and a member of buildingSMART German Chapter, GIF Frankfurt, the German-Hungarian Chamber of Industry and Commerce, and the German-Irish Chamber of Industry and Commerce.

Core offering

.bieker AG is an architecture and general-planning firm delivering end-to-end object and general planning services (HOAI Leistungsphasen 1–9) as a single-source contractor. Its core offerings span four service pillars — Consulting (funding, feasibility, ESG/DGNB), Architecture (full-scope object and general planning), Compliance (quality, fire protection, energy efficiency, occupational safety), and Digital Planning / BIM (BIM implementation, coordination, audit, custom Revit Add-ins) — complemented by two specialized verticals: Bestand (existing-building revitalization) and Datacenter (DIN EN 50600 data-center general planning).

Product overview

.bieker AG operates as an integrated architecture and general-planning practice organized as a portfolio of specialized service lines rather than a unified software product. The core offering spans four pillars — Consulting (advisory, feasibility, ESG/due diligence, funding consulting), Architecture (full-scope object and general planning with BIM by default), Compliance (quality, safety, regulatory adherence), and Digital Planning / BIM (BIM implementation, coordination, audit, custom Revit Add-ins, training) — complemented by two specialized verticals: Bestand (existing-building revitalization and DGNB-aligned retrofit) and Datacenter (DIN EN 50600-aligned data center general planning, the firm's flagship specialty). Sub-offerings Office Spaces and Retail Spaces extend the Architecture pillar into specific typologies. All services are delivered in-house or via coordinated specialist partners, with BIM as the standard digital methodology across the portfolio.
