Construction site regulations (BaustellV): Obligations, SiGeKo order and advance notice in practice

The Construction Site Ordinance (BaustellV) has been in force in Germany since July 1, 1998 and implements the EC Construction Site Directive 92/57/EEC into national law. It regulates the coordination of occupational safety on construction sites where several employers work simultaneously or one after the other and transfers central duties to the building owner or his commissioned third party. In practice, the BaustellV is, alongside the building regulations of the respective federal state and DGUV regulation 1, the most important legal basis for occupational safety in construction and applies to both commercial and private builders above defined threshold values. Violation of this can lead to fines according to § 25 ArbSchG as well as significant personal liability for the client and the people commissioned by him.

This article explains the three core obligations of the BaustellV (advance notice, SiGe plan, coordinator), the relevant threshold values, the interfaces between the client, SiGeKo, construction management and executing companies as well as the typical operational errors in implementation. You will find out when advance notice to the responsible supervisory authority is mandatory, what a SiGe plan contains, what qualifications a SiGeKo must have, how the order is documented and how the BaustellV obligations interlink with the construction manager role according to the state building regulations. Practical question checklists, an appointment certificate template and specific deadlines complete the presentation.

The BaustellV applies to all construction sites within the meaning of Section 1 Paragraph 3 BaustellV, i.e. to every place where construction work is carried out, including development, earthworks, civil engineering and building construction work, conversion, renovation and repair work. It applies regardless of whether the construction project is commercial or private; Private builders have the same obligations as commercial builders. According to Section 1 Paragraph 2 BaustellV, construction work that requires approval under the BImSchG as well as construction work that falls within the scope of application of the Federal Mining Act are excluded.

Three threshold values ​​define the scope of the obligation. Firstly, the obligation to appoint a coordinator according to Section 3 BaustellV: This applies as soon as employees from several employers work on a construction site at the same time or one after the other. In practice, this means: As soon as two different companies work on the construction site, a SiGeKo must be ordered. This also applies if the companies are not present at the same time because the construction site is considered a shared work location. Secondly, the obligation to give advance notice according to Section 2 Paragraph 2 BaustellV: It applies if the construction work is expected to last longer than 30 working days and more than 20 employees are working at the same time or the total amount exceeds 500 person-days.

Thirdly, the obligation to draw up a safety and health protection plan according to Section 2 Paragraph 3 BaustellV: It applies when the advance notice thresholds are reached or if particularly dangerous work is carried out are carried out in accordance with Annex II BaustellV, such as work with a fall height of over seven metres, work near high voltage, work with explosive substances or work in compressed air. The threshold values ​​are cumulative and are reassessed regularly throughout the construction process. The construction manager and SiGeKo role at CIVAC includes the ongoing monitoring of these thresholds and the timely updating of the mandatory documents.

The advance notice according to Section 2 Paragraph 2 BaustellV is a written or electronic report to the responsible supervisory authority (usually the respective occupational safety office or the district government) and must be presented at least two weeks before the construction site is set up. It must contain the information specified in Annex I BaustellV, in particular the location of the construction site, name and address of the client, type of construction project, expected start and end dates of the work, expected maximum number of employees on the construction site at the same time, expected number of employers and self-employed people, information about the coordinators and a description of the particularly dangerous work.

The advance notice must be clearly displayed on the construction site and updated in the event of significant changes, such as postponements of the construction period or increased number of employees. A lack of or incorrect advance notice is an administrative offense according to Section 25 ArbSchG in conjunction with Section 8 BaustellV and can be punished with a fine of up to 30,000 euros. In practice, incomplete information on the number of employees and particularly dangerous work is the most common complaint during official construction site inspections.

Who is responsible for advance notice depends on the specific order situation. In principle, the obligation lies with the client according to Section 4 BaustellV. If the building owner has commissioned a third party to carry out his duties (e.g. a project manager or an external safety and security agency), this task can be delegated. The order must be made in writing, clearly and with an appointment certificate. The appointment certificate, signed, filed, verifiable. In the official control process, the appointment certificate is the central proof that the duty has been properly delegated. The client's duty of supervision in accordance with Section 130 OWiG remains unaffected.

The safety and health protection plan, or SiGe plan for short, is the central working document for coordinating occupational safety on a construction site in accordance with Section 2 Paragraph 3 BaustellV. It is drawn up by SiGeKo in the planning phase and contains the overarching regulations for the cooperation between the executing companies, the chronological sequence of work with potential hazards, the shared facilities (scaffolding, cranes, sanitary facilities, first aid facilities) and the specific measures for the particularly dangerous work listed in Annex II. The SiGe plan must be kept on site and made accessible to all executing companies.

In terms of content, a typical SiGe plan is divided into six modules. Firstly, a description of the construction site with address, builder, planners involved and executing companies. Secondly, a construction schedule with identification of the interfaces and the work to be carried out simultaneously or one after the other. Thirdly, a risk assessment of the most important work steps with concrete protective measures. Fourth, a description of the shared facilities and transportation routes. Fifth, specific measures for Annex II work. Sixth, emergency regulations, first aid plan and alarm plans.

The SiGe plan is handed over to the executing companies before construction begins and is part of the contract. The SiGe plan must be updated whenever there are significant changes to the construction process, such as additions, new subcontractors or changed construction procedures. The update is documented and communicated to everyone involved. In the event of damage, an incomplete or outdated SiGe plan is a key indication of a breach of supervisory duty according to Section 130 OWiG. The deadline begins as soon as we become aware of it. The CIVAC workspace contains a SiGe plan template that covers all six building blocks in a standardised manner and supports updating with versioned history and automatic notification of all executing companies. Others run compliance like a filing cabinet. We run it like software.

The safety and health protection coordinator, or SiGeKo for short, must be appointed in writing by the client in accordance with Section 3 BaustellV. The appointment is made with an appointment certificate that regulates the area of ​​​​responsibility, the authorities, the reporting line and the remuneration. The order can include the client's own person or an external third party. In practice, construction managers or project managers are often appointed in parallel as SiGeKo on small construction sites, and a separate SiGeKo on larger construction sites. The order must be effective before the planning phase begins because the SiGeKo must already provide advice during the planning.

The qualifications of the SiGeKo are set out in RAB 30 (Rules for occupational safety on construction sites). A SiGeKo must have a construction qualification (engineer, technician or master craftsman) or a safety qualification (safety specialist, safety engineer) and have completed a specific SiGeKo training with at least 96 teaching units. In addition, there is at least two years of professional experience in construction management or occupational safety on construction sites. Regular further training with at least 16 teaching units every three years is recommended and is a prerequisite for awarding contracts for many clients.

The tasks of the SiGeKo in the planning and execution phase are conclusively regulated in Section 3 BaustellV. In the planning phase, he creates the SiGe plan and evaluates the temporal and spatial interfaces of the planned work. In the execution phase, he coordinates the application of the general principles of occupational safety, updates the health and safety plan, checks that employers are correctly applying the work processes and informs the client of any violations. The SiGeKo order and all updates must be fully documented in the construction file. Licence the workspace for your internal representatives, or have our representatives order it.

According to § 4 BaustellV, the builder is the main obligor and cannot evade his obligations simply by commissioning third parties. His duties cover six areas. Firstly, the appointment of a SiGeKo for construction sites with multiple employers. Secondly, advance notice to the supervisory authority when the threshold values ​​according to Section 2 Paragraph 2 BaustellV are reached. Thirdly, the creation of a health and safety plan when the advance notice thresholds are reached or in the case of particularly dangerous work according to Annex II. Fourthly, the consideration of the general principles of occupational safety according to Section 4 ArbSchG already in the planning phase.

Fifth, the creation of a document for later work on the building according to Section 2 Paragraph 5 BaustellV. This document documents the specific safety requirements for subsequent maintenance and repair work, such as anchor points for fall protection on the roof or information about asbestos or other hazardous substances in the structure. It is usually created by SiGeKo and handed over to the user together with the construction documentation. Sixth, the duty of supervision: The client must ensure that the SiGeKo he has appointed actually fulfils his tasks and intervene if there are indications of deficits.

The commissioning of a third party in accordance with Section 4 Sentence 2 BaustellV (e.g. a project controller or external general representative) is possible, but does not completely relieve the client of his obligations. The developer remains responsible for the proper selection and supervision of the agent. A missing or incomplete commission leads to personal liability of the builder in the event of damage, supplemented by Section 130 OWiG fines for breach of supervisory duties. The auditor calls, the evidence is ready. The construction manager and SiGeKo role at CIVAC ensures that all six mandatory areas are documented, fulfilled on time and verifiably filed in the construction file.

The BaustellV obligations overlap with the obligations of the construction management according to the respective state building regulations, but must be legally distinguished from them. The construction management according to the state building regulations (e.g. § 56 BauO NRW, Art. 50 BayBO) is responsible for the proper construction, i.e. the compliance of the building with the building permit and the generally recognised rules of technology. The SiGeKo function according to BaustellV, on the other hand, is limited to the coordination of occupational safety on the construction site and affects the employees of the executing companies, not the construction itself.

In practice, the two roles are often combined in one person, especially in small and medium-sized construction projects, because the professional qualification of a civil engineer or architect is required in both cases. In large projects with a construction volume of around 5 million euros, construction management and security management are often separated for efficiency and liability reasons because the dual role in the event of damage can lead to liability situations that are difficult to separate. Insurers are increasingly assessing dual roles as a risk factor and are demanding higher premiums or explicit exclusions from professional liability insurance.

The interface between construction management and SiGeKo is narrow during the construction process. The SiGeKo informs the construction management about safety-relevant deficits on the construction site; The construction management informs the SiGeKo about structural changes that influence the SiGe plan. Both roles report to the client, usually quarterly or ad hoc in special events. A clean reporting line is key evidence of exoneration in the event of damage. The interface is displayed in the CIVAC workspace as a common template in which construction management and SiGeKo can document and communicate at the same time, with versioned history and audit trail according to 93 controls of ISO/IEC 27001:2022.

In supervisory practice, seven BaustellV violations occur particularly frequently. Firstly, the lack of a SiGeKo order on construction sites with multiple employers. This is the most common complaint during official inspections and is punished with a fine of up to 5,000 euros per complaint. Secondly, the lack of advance notice when the thresholds are reached. Building owners often underestimate the 500 person-day threshold, which is reached after just 63 working days on a construction site with eight employees. Thirdly, an outdated or incomplete SiGe plan that was not updated after changes to the construction process.

Fourthly, the lack of a document for later work on the building in accordance with Section 2 Paragraph 5 BaustellV. This obligation is particularly often forgotten in practice because it relates to later use and is not very visible during the construction phase. In the event of damage, such as a fall during later roof renovations, the absence leads to significant liability for the builder. Fifthly, the failure to post the advance notice on the construction site, which is considered an administrative offense. Sixth, insufficient qualifications of the SiGeKo, for example if a construction manager without SiGeKo training is appointed as a SiGeKo, which can make the entire appointment ineffective.

Seventh and particularly relevant to liability: the lack of a reporting line and documentation between SiGeKo and the client. If the SiGeKo does not report deficiencies on the construction site to the building owner in writing and the building owner does not intervene as a result, both parties may be personally liable. Audit-proof, documented, § 130-OWiG-proof is the short formula for the construction act documentation that decides in the event of damage. CIVAC provides standardised templates, reminder logic and an audit trail for all seven violations in a workspace that maps the BaustellV obligations together with the other compliance obligations of the construction site, such as asbestos, hazardous substances and fire protection.

The classic BaustellV documentation takes place in paper folders or scattered Excel and Word documents, which quickly becomes confusing when there are several parallel construction sites. Building owners with five or more construction sites running at the same time, such as general contractors, project developers and property owners, benefit significantly from a digital platform that bundles all BaustellV documents in one place and makes them searchable. Such a platform reduces the administrative effort for the building owner and SiGeKo by 30 to 50 percent compared to classic folder storage and shortens the response time for official inquiries to a few minutes.

The platform functions typically include six modules. Firstly, a module for advance notification with a standardised input mask, automatic threshold calculation and electronic transmission to the supervisory authority. Secondly, a SiGe plan generator with the six standard building blocks and templates for the most common Annex II work. Thirdly, an order and reporting line module with appointment certificates, confirmations and reporting calendar. Fourthly, a module for the document in accordance with Section 2 Paragraph 5 BaustellV with structured recording of the maintenance requirements, anchor points and the documented hazardous substances in the finished structure.

Fifthly, an audit trail module that documents all changes with a time stamp, author and version status and can therefore prove the status of the documentation at any time in the event of damage. Sixth, a reporting module for management and insurers that shows the status of BaustellV compliance per construction site and aggregated across the entire portfolio. CIVAC offers these six modules in a workspace with EU data residency, 93 controls according to ISO/IEC 27001:2022 and 490 ready-to-use templates that, in addition to the BaustellV, also cover the related compliance fields of asbestos, hazardous substances, fire protection and environmental protection. Licence the workspace for your internal representatives, or have our representatives order it.

The Construction Site Ordinance has been the central legal basis for occupational safety on construction sites since 1998 and will remain an often underestimated area of ​​responsibility in practice in 2026. Builders with several parallel construction projects, project developers and general contractors are particularly challenged because the BaustellV obligations must be fulfilled separately for each construction site, with their own SiGeKo order, their own SiGe plan and their own advance notice. Anyone who does not carry out this discipline in a structured and platform-supported manner not only risks fines of up to 30,000 euros per violation, but also personal liability in the event of damage and breaches of supervisory duties according to Section 130 OWiG with a fine limit of up to one million euros.

CIVAC is a German compliance platform and officer-as-a-service. We offer two models for the BaustellV. In the platform model, you licence the workspace, keep your internal construction manager or SiGeKo and use the modules for advance notice, SiGe plan, order and reporting line, with EU data residency and 93 controls according to ISO/IEC 27001:2022. In the service model, CIVAC also orders an external SiGeKo with an appointment certificate within two working days instead of the industry-standard two to six weeks, who takes over operational coordination and reports to the management on a quarterly basis. Licence the workspace for your internal representatives, or have our representatives appointed.

If you want to document the BaustellV obligations in a structured manner for your 2026 construction projects, have a BaustellV compliance audit created. Within three weeks, we deliver a gap analysis for each ongoing construction site, a template for the appointment certificate and SiGe plan as well as a roadmap for platform-based documentation. Send a short inquiry to info@civac.de or using the contact form on civac.de with keyword BaustellV. We will respond within one working day with a concrete proposal for a 30-minute initial consultation. Turn reading into an assignment.
