DELTA Engineering GmbH is a software company based in Zurich and founded in 1992. It provides software such as DELTAproject and DELTAbauad for the Swiss construction industry. Its positioning is not that of a general-purpose collaboration SaaS platform, but rather a toolset built around architectural firms and construction administration, covering project documentation, bills of quantities, costs, working hours, payment schedules, and drawing workflows.
Based on the information available on the site, DELTAproject covers address and project management, correspondence, meeting minutes, construction administration, cost control, time and expense entry, project controlling, payment schedules, drawing management, and drawing distribution. DELTAbauad focuses more on costing and construction administration, supporting cost estimates based on BKP or eBKP, bill of quantities preparation using NPK/CRB together with SIA451, as well as company account cost control, payment instructions, and payment orders. The time-tracking module supports graphical entry, analysis by activity and SIA phase, and comparison against contractual fees.
The publicly available content does not disclose pricing, plans, subscription or perpetual-license models, nor does it clarify whether the product is cloud-based, self-hosted, or delivered as a local client. However, the site does explicitly mention that DELTAproject can be explored via a Live-Präsentation or Testversion, which is important for evaluating specialist software. Information on APIs, third-party integrations, permission systems, backups, and security policies was not present in the captured content.
Its main strength is a strong fit with Swiss construction industry standards. The site lists multiple CRB-related certifications, including IfA 18, CRB/Online, and NPK-IfA, indicating accumulated experience in the local regulatory and standards environment. Its feature chain spans projects, costing, time tracking, and drawings, making it suitable for small to mid-sized architectural firms that need structured management. The downside is limited transparency around commercial information, along with a lack of the integration, open API, permissions, and compliance details commonly expected from modern SaaS products. Its suitability for other regions is also difficult to assess.
It is best suited to architectural firms, cost-estimation teams, and construction management teams that work within the Swiss CRB/SIA framework. For Chinese users whose projects do not involve Swiss standards, local tools such as 广联达, 鲁班, 品茗, and 筑业 may be more appropriate, while general collaboration tools such as 飞书项目 and Teambition can also be used to supplement project management. There is no evidence in the source text regarding access from mainland China, so it is marked as unknown; payment methods are also not disclosed.
