About Der Bausachverständige

Der Bausachverständige

Der Bausachverständige is the specialist journal for construction and real-estate experts: the Fachzeitschrift "für Bauschäden, Baurecht und gutachterliche Tätigkeit" — six issues a year, now in its 22nd volume (2026) — published jointly by the Reguvis Fachmedien GmbH in Cologne and the Fraunhofer IRB Verlag in Stuttgart. Its formula — "von Praktikern für Praktiker / von Experten für Experten" — serves the Bau- und Immobiliensachverständige and everyone dealing with building defects, building technology and construction law from a technical or legal perspective. With two independent editorial offices — engineers in Stuttgart, lawyers in Cologne — the journal unites the two cultures of expert practice: the building and the law.

Overview

Der Bausachverständige is the working journal of the German construction-expert profession. The readership — publicly appointed and certified Sachverständige for construction and real estate, engineers, architects, lawyers — lives at the intersection of Bautechnik and Baurecht: the expert's report (Gutachten) must be technically sound and legally defensible. The journal's dual editorship mirrors that duality: the Fraunhofer IRB Verlag's technical editorial office (building engineers) and the Reguvis Fachmedien's legal editorial office (lawyers) jointly produce each issue.

The six-issues-a-year rhythm follows the expert's year: the building seasons, the court calendars, the continuing-education cycles. Each issue delivers current, practice-oriented specialist information across the two pillars: from building technology — building defects and renovation, building in existing stock, building technology and building physics, the newest from building research — and from construction law — expert law, report and fee questions, construction and real-estate law — plus press releases and news from associations, politics, the construction industry and current case law, plus literature and event tips, continuing-education offers, information on norms and guidelines.

The journal's institutional backing is unusual: leading associations and institutions of the expert profession are integrated into the editorial work, ensuring a balanced spectrum of opinion, and a competent advisory board (Beirat) from all areas of planning, building and construction law supports the editors. The ISSN is 1614-6123; the 2026 volume is the 22nd — the journal's founding thus dates to around 2005.

History

Der Bausachverständige was founded around 2005 as a joint venture of two publishing cultures: the Reguvis Fachmedien GmbH (Cologne) — the specialist publisher grown from the Bundesanzeiger-Verlag tradition, serving law and business professions — and the Fraunhofer IRB Verlag / Fraunhofer-Informationszentrum Raum und Bau (Stuttgart) — the information center for space and building of the Fraunhofer-Gesellschaft, the applied-research organization. The partnership's logic: the construction expert needs both the engineer's building knowledge and the lawyer's legal precision, and each publisher brought its strength.

The journal's digital evolution followed the profession's: with issue 1/2016 the BauSV E-Journal made the magazine readable on tablet and smartphone; the BauSV Premium subscription opened the online archive — the digital BauSV library with the editorial contributions of all published volumes, hundreds of commented court decisions, the BAULIT literature database on building defects — searchable through databases. The "BauSVkompakt" special publications — such as the combined volume on the new waterproofing norms (DIN 18531, DIN 18532) — extended the brand into compact technical guides.

Through two decades the dual-editorship model has held: the technical editors in Stuttgart (Dipl.-Ing. Thomas Altmann, responsible; Viola Pusceddu) and the legal editors in Cologne (Rechtsanwalt Nicolas Störmann, responsible; Elke Ehring) — two independent, engineer- and lawyer-staffed editorial offices ensuring specialist quality and practical relevance. The 22nd volume (2026) documents the continuity: the journal of the construction expert, still appearing six times a year.

Coverage and Content

The editorial program follows the expert's working agenda. The building-technology coverage — the Bautechnik — spans building defects (Bauschäden) and renovation (Bausanierung), building in existing stock (Bauen im Bestand), building technology and building physics (Bauphysik), to the newest from building research: the technical foundation of the expert's report. The construction-law coverage — the Baurecht — spans expert law (Sachverständigenrecht), report and fee questions (Gutachten-/Honorarfragen), to construction and real-estate law: the legal framework of the expert's mandate.

The news coverage — the Pressemeldungen and Nachrichten — carries association news, politics and construction-industry developments, and current case law (Rechtsprechung): the profession's environment. The service coverage — the Literatur- und Veranstaltungshinweise, the Weiterbildungsangebote, the Normen and Richtlinien information — serves the expert's continuing education and standards compliance. The event calendar on bausv.online lists the profession's training events.

The special-publication coverage — the BauSVkompakt volumes — deepens technical themes in compact form: the waterproofing-norms volume (DIN 18531 for roofs, DIN 18532 for traffic surfaces of concrete, with foundations, slopes, composite waterproofing, solar roofs, detail designs) exemplifies the format. The Premium archive — the digital BauSV library — deserves its telling. The BauSV Premium subscription unlocks the online archive: the editorial contributions of all previously published journal volumes, made searchable through databases; hundreds of court decisions (Gerichtsurteile) with comments; the BAULIT Bauschäden literature-reference database; the relevant specialist literature on building defects. The trial subscription — the Premium Kennenlern-Abo (three printed issues plus E-Journal and online access during the term) — opens the system to new readers. The archive's function — the Premium's — turns the journal into the daily working tool: the expert researching the defect finds the decisions, the literature, the articles — the 22 volumes as a database — the profession's memory, searchable.

Organization and Ownership

Der Bausachverständige is published jointly by the Reguvis Fachmedien GmbH (Postfach 10 05 34, 50445 Köln; subscription service 0221/98231-850, service@reguvis.de) and the Fraunhofer IRB Verlag / Fraunhofer-Informationszentrum Raum und Bau IRB (Postfach 80 04 69, 70504 Stuttgart). The technical editorial office sits with Fraunhofer IRB in Stuttgart (Dipl.-Ing. Thomas Altmann, responsible editor; Viola Pusceddu); the legal editorial office with Reguvis in Cologne (Rechtsanwalt Nicolas Störmann, responsible editor; Elke Ehring).

The dual editorship — the two cultures — deserves its telling. The Stuttgart technical office — Dipl.-Ing. Thomas Altmann (responsible), Viola Pusceddu — staffs the Bautechnik with building engineers: the defects, the physics, the research. The Cologne legal office — Rechtsanwalt Nicolas Störmann (responsible), Elke Ehring — staffs the Baurecht with lawyers: the expert law, the fees, the decisions. The two offices are independent: each ensures the specialist quality and practical relevance of its pillar, and the advisory board (Beirat) from all areas of planning, building and construction law supports both. The leading associations and institutions of the expert profession are integrated into the editorial work — VDI, BVS and others — guaranteeing the balanced opinion spectrum. The editorship's function — the dual's — is the journal's identity: the building and the law, the engineer and the lawyer, in one magazine — the expert's two cultures, edited jointly. Selected authors from the practice of the construction and expert profession contribute their knowledge; the advisory board and the integrated associations ensure the balanced opinion spectrum. Detailed circulation, staffing and revenue figures are not publicly confirmed.

Digital Presence

The journal's digital home is bausv.online: the portal for the magazine, the event calendar (Veranstaltungskalender), the reading samples (Leseproben) and the BauSVkompakt special publications. The BauSV Premium online archive — the digital BauSV library — makes all published volumes' editorial contributions, hundreds of commented court decisions and the BAULIT literature database searchable. The BauSV E-Journal (since 1/2016) brings the magazine to tablet and smartphone; a dedicated app ("Der Bausachverständige") has carried the E-Journal to mobile devices.

The digital strategy follows the specialist-publisher logic: the print journal for the six-issue deep read — the defects, the law, the reports — the digital archive for the working tool — the searchable decisions, the literature database, the E-Journal. As the construction expert's journal — the Reguvis/Fraunhofer IRB co-publication (the dual editorship, the 22nd volume, the Premium archive) — Der Bausachverständige remains the profession's paper: the Fachzeitschrift for building defects, construction law and expert practice, in print and at bausv.online.
