BAUSW

What BAUSW does

BAUSW (legally BAU Software s.r.o.) is a Czech Republic-based software company, headquartered in Brno, that develops an electronic construction diary platform for the construction industry. The product is a Docker-based web application backed by SQLite, architected as a Progressive Web App that supports offline mode with automatic synchronization, and is deployed exclusively on customer infrastructure. Core functionality includes a digital construction diary, Qualified Electronic Signatures compliant with the EU eIDAS regulation in PAdES format, immutable audit trails, photo and PDF annotation, kanban task management, timesheet and attendance tracking, and role-based access control. Two adjacent products are BAUSW Track, a mini-application for construction workers that records attendance via 8-digit codes without requiring a main application account, and ALTCHA, a separate sub-brand offering GDPR-compliant, proof-of-work-based spam protection.

The company sells through an enterprise field sales motion with personalized demos and quote-based pricing on a perpetual on-premise license, intentionally avoiding SaaS subscription economics in order to serve buyers with strict data sovereignty requirements. It targets five vertical segments: government and public administration, healthcare facilities, construction companies, private developers, and municipalities. Compliance positioning emphasizes GDPR data protection, eIDAS-qualified digital signatures, and full customer data ownership without third-party sharing.

The platform integrates with Active Directory, Microsoft Azure AD, and Google OAuth for identity; AWS S3, Azure Blob Storage, and Cloudflare R2 for S3-compatible file storage; and the Visual Crossing Weather API for automatic weather population in diary entries. Founded in 2023 by Daniel Regeci, who serves as Founder and CEO, the company claims to serve thousands of government institutions and businesses globally and has not disclosed external funding or revenue.

Core offering

BAUSW is an on-premise electronic construction diary software that provides real-time project documentation, EU eIDAS-compliant digital signatures (QES/PAdES), Kanban-based task management, timesheet tracking, photo/PDF annotations, and immutable audit trails. It is deployed via Docker on the customer's own infrastructure, giving organizations complete data ownership, GDPR compliance, and freedom from vendor lock-in. Companion mini-app BAUSW Track enables construction worker attendance logging via an 8-digit code with offline sync.

Product overview

BAUSW is a single unified product—a web-based Electronic Construction Diary platform designed for the construction industry. The core BAUSW platform provides digital construction diary functionality with modules for diary entries, tasks (Kanban), timesheets, documents, annotations, electronic signatures (eIDAS compliant), PDF signatures, notifications, and audit trails. BAUSW Track is a companion mobile mini-app for construction workers to log time and track tasks. A related product is ALTCHA, a separate GDPR-compliant spam protection platform. The platform is deployed on-premise (self-hosted) with no cloud dependency, and supports Docker-based deployment with integrations for SSO (Active Directory, Azure, Google), S3-compatible storage (AWS S3, Azure Blob, Cloudflare R2), and Visual Crossing weather API.

Direct peers

• Fieldwire: Fieldwire offers field management for construction teams including task management, drawings, and daily reporting. It is a direct alternative to BAUSW for contractors looking to digitise site documentation and task workflows, with similar offline-first mobile emphasis.
• iAuditor (SafetyCulture): SafetyCulture's iAuditor is a mobile inspection and checklist platform widely used on construction sites for daily reports and compliance documentation. It is comparable to BAUSW's diary and annotation features and targets similar frontline-construction personas.
• Raken: Raken provides mobile-first daily reporting, time tracking, and field productivity tools for construction crews. It is closely comparable to BAUSW's diary-plus-timesheet (BAUSW Track) workflow, targeting general contractors with similar field-data capture use cases.
• LetsBuild: LetsBuild (now part of Procore) provided construction site diary, quality and safety reporting for European contractors. Its product overlap with BAUSW's electronic construction diary and on-site documentation features makes it a directly comparable peer.
• PlanRadar: PlanRadar is a SaaS platform for construction documentation, defect management, and site diaries used by contractors and project owners across Europe. It directly competes with BAUSW's electronic construction diary in the same buyer segments (general contractors, developers, public-sector clients).

Broad incumbents

• Autodesk Construction Cloud: Autodesk Construction Cloud bundles BIM, document management, and field collaboration for construction. It overlaps with BAUSW at the project-documentation and audit-trail level and competes for the same enterprise and government construction accounts.
• Procore: Procore is the leading end-to-end construction project management platform with daily log, drawings, RFIs, and field productivity tools. It is a broad incumbent in BAUSW's space, offering overlapping capabilities (including via its LetsBuild acquisition) but serving a much wider portfolio.

Emerging players

• DocuWare: DocuWare provides document management, workflow automation, and electronic signature for regulated European organisations. It overlaps with BAUSW on the document-and-signature side of construction project documentation, particularly for public-sector and compliance-driven buyers.
• Buildertrend: Buildertrend is a construction project management platform focused on residential builders and remodelers. It competes with BAUSW for the private-developer / construction-company segment with overlapping daily-log and document-management features.

Others

• OpenGov: OpenGov sells procurement, permitting, and transparency software to US state and local governments. It is adjacent rather than directly competitive, but it overlaps with BAUSW in serving government buyers with transparency, accountability, and audit-trail requirements for public projects.
