Innovators at these companies trust us
The local challenge
Construction and real estate companies in Dortmund face a double challenge today: they want to use AI to accelerate projects and win tenders, but at the same time must protect sensitive planning data, personal information and security-relevant protocols. Mistakes in data handling or traceability can cost not only money but also trust.
Why we have local expertise
Reruption is based in Stuttgart, travels regularly to Dortmund and works on-site with clients – we enter site offices, meet project managers and discuss with architectural firms as well as facility management teams. This proximity allows us to design technical solutions so they fit into daily on-site workflows: from secure self-hosting architectures to audit logs that meet the requirements of regional clients.
Our work combines deep engineering with entrepreneurial responsibility: we are not external consultants who write reports and leave; we build prototypes, test them in real processes and support implementation. For clients in North Rhine-Westphalia this means pragmatic solutions that align with actual operational procedures.
Our references
In engagements with a strong compliance focus, we draw on experience from consulting and technology projects. In projects with FMG, for example, we developed data-driven research and analysis workflows that require strict traceability and auditability – an approach directly transferable to project documentation in the construction sector.
For consulting mandates with sustainability and strategic focus, we worked with Greenprofi, which gave us an understanding of long-term governance, retention and classification strategies – central for real estate portfolios and long-term construction projects.
We bring technical depth from projects with technology partners like BOSCH and experience with industrial customers such as STIHL: we know the requirements for robust, secure embedded and cloud architectures as well as the processes to keep systems compliant over long product lifecycles.

AI Security & Compliance for construction, architecture and real estate in Dortmund
The use of AI in construction and real estate projects promises significant efficiency gains: faster tendering, improved planning quality, automated project documentation and ongoing compliance checks. At the same time the risk increases: sensitive plans, personal data of clients and workers, and security-relevant protocols must remain protected and auditable. In Dortmund, a city actively shaping the transition from steel to software, these requirements are particularly salient.
Market analysis and local drivers
Dortmund today is a mix of logistics, IT, insurance and energy companies. Construction and real estate actors often collaborate with partners from these sectors: logistics companies plan hub spaces, insurers require proof of risk mitigation, energy providers demand concepts for integrating charging infrastructure or energy efficiency. These cross-sector requirements drive the need for transparent, vetted AI use.
For real estate developers and architectural firms this means: compliance is no longer a nice-to-have but a competitive factor. Tenders require traceable data use and audit readiness; investors review data governance, and public clients expect data protection concepts. AI Security & Compliance thus becomes part of the market access strategy.
Specific use cases for construction, architecture & real estate
Tender copilots: AI assistants that draft tender documents, filter bidder responses and flag risks significantly speed up the process. Without strict access controls and audit logs, however, decisions become unverifiable. That is why we integrate model access controls & audit logging to make every recommendation traceable back to the data source.
Project documentation and versioning: construction projects generate a flood of plans and revision states. Here, data governance modules for classification, retention and lineage help, combined with secure self-hosting solutions to keep sensitive architectural plans out of public APIs. A robust retention and archiving concept ensures historical states remain traceable – important for project handovers and legal disputes.
Compliance checks and safety protocols: automated checks can monitor contracts, standards and safety requirements. To minimize the risk of incorrect outputs, we implement privacy impact assessments and AI risk & safety frameworks before rollout. Regular red-teaming and evaluations protect against misuse and unintended data leaks.
Implementation approach and architectural decisions
Our preferred approach starts with a clearly defined PoC: use-case definition, feasibility assessment and prototyping in a short timeframe. For Dortmund construction companies this means we can quickly demonstrate whether a tender copilot provides commercial and legal value without immediately overhauling the entire IT infrastructure.
Technically we rely on modular, secure architectures: where possible self-hosting & data separation to keep sensitive content local; if cloud components are necessary, then with strict encryption, tokenization and access controls. Audit logging and model access management are mandatory so that every model request can be documented.
Success factors and common pitfalls
Successful projects combine technology, process and organization. A common mistake is focusing only on the model and neglecting governance. Without clear classification rules and retention policies, long-term risks arise: uncontrolled data accumulation, compliance violations and rising audit costs.
Change management is equally critical: architectural firms and site managers must understand how AI recommendations are generated and what verification mechanisms exist. Training, clear role descriptions and a pilot area where the technology can be tested are necessary to build trust.
ROI, timeline and organizational requirements
A typical PoC at Reruption costs €9,900 and delivers a working prototype with performance metrics and a clear production plan within a few weeks. For real estate projects the ROI can become visible within months: faster bid processing, fewer reworks and lower compliance costs.
Organizationally, companies need an executive sponsor, a small interdisciplinary team (IT, data protection officer, business unit) and regular review cycles. We support the establishment of this governance structure and provide templates for ISO 27001- or NIST-compliant documentation.
Technology stack and integration issues
The technical stack includes secure hosting options, encryption at rest and in transit, access management and monitoring tools. For many clients in Dortmund a hybrid solution makes sense: sensitive plans remain within the corporate network, while less critical features can run in vetted cloud containers.
Integrations with existing DMS, BIM or ERP systems are often necessary. The biggest challenge here is not the technology but data quality and a metadata strategy. We provide integration adapters and data-lineage configurations that ensure auditability and traceability.
Change management, training and sustainability
User acceptance is not an afterthought: only those who understand the limits and opportunities of AI will use it correctly. We offer training on safe prompting & output controls, explain common sources of error and train teams in interpreting automated suggestions.
Beyond short-term effects we think long-term: compliance automation, regular red-teaming exercises and a documented roadmap ensure that AI solutions remain secure and compliant even after organizational changes or technology updates.

Key industries in Dortmund
Over the past decades Dortmund has transformed from a center of steel and coal into a diverse economic location. Today logistics companies shape the cityscape with large depots and transshipment areas, IT firms drive digital innovation, and insurers and energy providers play an important role in regional value chains. This industry mix creates diverse requirements for construction and real estate projects.
The logistics sector demands flexible warehouse spaces and efficient space planning — AI-powered tools can help optimize space utilization, but sensitive location data must be protected to avoid competitive disadvantages. Security and compliance requirements are high because site plans are often disclosed in tender documents.
IT companies in Dortmund drive demand for modern office and data center solutions. For developers this means smart buildings that combine data security and energy efficiency. AI is used here for predictive maintenance and energy optimization, but these systems must be designed so they do not create vulnerabilities for data theft or manipulation.
Insurers in the region require transparent risk assessments and traceable documentation of construction and safety measures. Real estate developers must therefore integrate audit readiness and traceability into their project processes so that insurance premiums and liability issues can be negotiated cleanly.
The energy sector around RWE and other providers imposes requirements on the integration of charging infrastructure, energy storage and grid integration. For builders and architects this creates complex compliance tasks, for example in grid connections or energy standards — AI can automate these processes, but only with clear governance rules.
Overall the development shows: demand for digitized, intelligent buildings is rising, and with it the need for robust AI security and compliance frameworks that take local regulatory specifics and the cross-sector requirements of logistics, IT, insurance and energy into account.

Frequently Asked Questions
A tender copilot often processes confidential documents and personal data of bidders. The first step is a clear use-case definition: which data may be used, which may not, and which outputs are permissible? This is followed by a data protection impact assessment (DPIA) that evaluates risks to affected parties and defines technical and organizational measures.
Technically we recommend self-hosting or strictly separated environments for sensitive tender data, complemented by model access controls and complete audit logs. This makes it possible to trace every model request back to the input source and demonstrate compliance with data protection requirements.
Organizationally, roles and responsibilities must be defined: who may feed the system, who validates outputs, and who is responsible for data deletion? Frequent training and protocols for reviewing model outputs prevent misuse and build trust with bidders and clients.
Practical takeaways: start with a PoC, conduct a DPIA, implement logging and access controls, and establish clear processes for review and deletion. This improves your legal standing and increases acceptance among internal stakeholders.
ISO 27001 provides an established framework for information security management and is particularly valuable when multiple business units or external partners are involved in AI projects. For construction and real estate projects, ISO 27001 ensures that information risks are systematically identified, assessed and reduced.
In practice we use ISO 27001 elements to define policies for data classification, access control and incident response. These policies form the basis for technical measures such as encrypted storage, network segmentation and role-based access.
For smaller companies, full ISO certification can be a significant investment. We offer compliance automation and templates that implement ISO principles in a pragmatic, staged approach so that SMEs can quickly achieve audit readiness.
Concrete advice: start with a gap analysis against ISO 27001, prioritize measures by risk and effort, and use automation to produce recurring audit evidence. This way security becomes an enabler rather than a bottleneck.
Safe prompting means designing inputs so that models produce predictable, verifiable and safe responses. In planning workflows this means using standardized input templates, requiring mandatory context fields and introducing output templates that include clear indications of uncertainty and source references.
Technically we implement output controls via rule engines that filter results based on criteria: no sensitive details, warning flags for uncertainty, and mandatory source citations. Combined with audit logs, every recommendation can be reviewed later.
Organizationally, responsible parties must be defined who approve outputs before they are included in official documents. This reduces the risk of erroneous model suggestions entering contracts or tender documents unchecked.
As a practical step we recommend a pilot phase in a delimited project, rollout with training for users and implementation of monitoring to continuously improve the performance of prompting strategies.
Protecting sensitive architectural plans starts with data locality: where possible, plans should remain in controlled on-premises or private cloud environments. Data should be strongly encrypted at rest and in transit. Tokenization can anonymize sensitive elements such as owner information.
Additionally, access rights should be controlled granularly. Role-based access controls and just-in-time access processes reduce the risk of unintentional exposure. All accesses must be documented via audit logging so it is traceable who viewed or processed which file and when.
For AI-specific processes data separation is crucial: training data, inference data and log data must not be mixed. Secure self-hosting & data separation provide a robust solution here. Regular red-teaming exercises and penetration tests verify the effectiveness of protective measures.
Practical recommendation: create a data classification scheme, encrypt according to sensitivity, implement granular permissions, and conduct regular audits. These steps are the foundation for any secure AI operation.
Reruption’s typical entry pipeline starts with a PoC (proof of concept) that we offer for €9,900. Such a PoC typically delivers a working prototype, performance metrics and a production plan within a few weeks. The goal is to validate technical feasibility and commercial benefit early on.
For productive implementation the duration depends heavily on scope: integration into DMS or BIM systems, implementation of self-hosting and alignment with data protection policies take more time. A lean MVP can go live in 2–4 months; comprehensive, cross-organizational implementations often require 6–12 months.
Iterative delivery is important: short cycles, concrete deliverables and continuous monitoring reduce risks and increase business value. We recommend defining business KPIs early and regularly aligning them with technical metrics.
Practical takeaways: plan the entry as a PoC, define KPI and compliance metrics, and expect a staged rollout that yields first successes within weeks and full integration within a year.
Red-teaming is a targeted, simulated attack approach to uncover vulnerabilities in AI systems before real attackers or misuse occurs. For real estate projects this means testing scenarios such as data manipulation, inference attacks or unauthorized data queries.
Regular evaluations help to understand model behavior under unusual conditions and improve output controls. They are also an important element for audit readiness: well-documented red-teaming results show auditors that risks have been identified and mitigated.
Operationally, red-teaming includes test data, attack vector analyses and post-mortem reports with concrete measures. These results feed into AI risk & safety frameworks, DPIAs and update plans.
Our recommendation: plan red-teaming as a recurring process, not just a one-off activity. This ensures that security measures keep pace with the evolution of models and processes.
