Seven subject areas, seven documented discrepancies between what should be and what is. In a Geesthacht school built in 1995 and used daily by minors, fall protection is missing, fire safety documentation cannot be found, and the air is too poor to concentrate. This is not a rumour — it is the content of an official status report.
Background: What the Report Contains
The present status report analyses the structural and safety-related actual condition of a Geesthacht school built in 1995 across seven categories. The methodology is clear: each subject area is assessed against the applicable safety standard, the actual finding is documented, and the discrepancy is named. The result is not an opinion piece but an enumeration of conditions that ought not to exist.
Remarkable is not only what the report contains, but also what it reveals about the period in which the deficiencies arose. The oldest problems go back to the year of construction, 1995. Others became apparent at the latest during renovation work in 2009/2012. The most recent official document — a notice regarding missing fire safety certification in the building permit file — is dated 11 May 2026. This means: some of these deficiencies have not been newly discovered. They have been administered for years.
All seven subject areas analysed show a documented discrepancy between the required safety standard and the structural reality. Not a single area is without a finding.
I. Fall Protection: 40 cm Instead of 80 cm
The guidelines for school buildings in force at the time of construction required window parapets with a minimum height of 80 centimetres, or alternatively a railing of 1 metre. The installed parapets measure only approximately 40 centimetres. Due to fixed benches installed directly in front of the windows, the effective protection is further reduced: someone standing on the bench clears the parapet with around 60 centimetres of remaining height and no meaningful barrier.
In addition: the glazing on the exterior and in the surrounding corridors from the first upper floor upwards does not have fall-arresting properties. This means that a pane subjected to mechanical stress — for instance by a person pressing against it or falling — can break. The person then does not fall against the glass but with the glass.
A further aggravating factor: glazing that extends from floor level up to a height of two metres and is freely accessible must, under the applicable guidelines, have fall-arresting properties — that is, be made of safety glass. This requirement is also not met on the exterior facade and in the surrounding corridors from the first upper floor upwards. Insufficient parapet height and missing glazing to safety glass standard thus constitute two independent deficiencies within the same subject area.
This is not a theoretical risk, and it is not a new finding. A senior engineer from the Unfallkasse Nord assessed the situation on-site and reached an unambiguous verdict: the safety regulations then mandatory (GUV 16.3) had been "criminally" disregarded by the architect. The entire glazing from the first floor upwards lacked safety glass, meaning "virtually no effective fall protection exists whatsoever." The Fachdienst Hochbau has simultaneously commissioned a structural engineer to examine retrofit fall protection options. A reliable result is not yet available at the time of reporting.
IIa. 2020 to 2026: The Documented Inaction
Knowledge of the missing fall protection is not new. The internal administrative memorandum is dated 13 July 2020: on that day, a representative of the Unfallkasse Nord recommended by telephone to a case officer at the Fachdienst Immobilien the "subsequent installation of a fall protection barrier of 1.00 m in front of the windows" — a direct, concrete recommendation from the responsible statutory accident insurer. The memorandum records what happened next: the case officer internally declined to act and noted that he "would wait out the summer holidays." The railings were not installed.
Five and a half years later, in January 2026, the head of the Fachdienst Hochbau attempted to treat the 2020 matter as closed. In an email dated 15 January 2026 to the senior engineer of the Unfallkasse Nord, the department head claimed that the issue had been "essentially conclusively resolved" by the Unfallkasse at that time. The engineer contradicted this account the same morning, at 11:28 a.m.: he feared "that the situation has not eased", and reminded the department head of the obligation to retrofit that had not been fulfilled since 2020. The department head responded that the facade offered "poor structural conditions" for railings. The retrofit did not take place.
The senior engineer of the Unfallkasse Nord explicitly named the legal consequences of an incident: should a fatal fall occur, the public prosecutor would inevitably "investigate for negligent homicide", as the failure to install the protection constituted an "avoidable breach of duty of care." This assessment does not come from a critic — it comes from the statutory accident insurer responsible for school accidents.
The engineer also pointed out that in modern teaching, constant supervision of pupils at open windows is practically impossible. The expectation that teachers could substitute for missing railings through supervision is thus professionally off the table.
II. Building Documentation: Gaps with Consequential Costs
When additional emergency exit doors were installed in 2009 and 2012, documented deviations between the building plan and actual construction came to light. Contrary to the plans, the facade had not been suspended from the roof but was standing on the ground. Non-functional screws had been used. The thermal insulation had rotted due to moisture.
Verification against the original plans was not possible: the architectural firm had lawfully destroyed them after the statutory retention period had expired. Structural modifications during the construction phase had not been documented with the administration.
Rectifying the concealed deficiencies from the original construction has caused 550,000 euros in construction costs and 50,000 euros in planning costs — a total of 600,000 euros for errors that could have been avoided or detected earlier with complete documentation.
The finding raises an uncomfortable question: if the documentation of the original construction was so incomplete, how reliable are the assumptions on which current safety inspections are based?
III. Air Quality: Windows Shut, CO2 Rising
Because the windows do not have effective fall protection (see Section I), mechanical opening restrictors were installed as an immediate measure. The windows can since only be tilted to approximately 15 centimetres or opened to a gap of 10 to 12 centimetres. Cross-ventilation — the most effective method for rapid air renewal — is thus structurally prevented.
The consequences are measurable: CO2 monitors installed in 18 rooms regularly show values between 1,000 and over 1,400 ppm during lessons. Above 1,000 ppm, indoor air quality is classified as "notable" according to common reference values; above 1,400 ppm as "no longer acceptable." Pupils and teachers consequently report headaches, nausea, and fatigue.
An official memorandum dated 26 February 2026 explicitly states that pupil numbers in individual rooms are not in a reasonable proportion to the available floor area. This is an internal administrative finding of overcrowding — not external criticism.
The logic of this situation is circular: the windows were restricted because they lack fall protection. Because the windows are restricted, the air is poor. Because the air is poor, health complaints arise. Neither of the two underlying problems has been resolved.
IV. Fire Safety: Certification Not in the File
For a special-use building with a central atrium such as this school, substantive certification on smoke extraction is part of the building permit file. It must document how, in the event of fire, smoke is removed from classrooms, corridors, and the central hall.
A notice from the competent authority dated 11 May 2026 — not a rumour but an official information access notice — officially confirms: this certification is not in the file. Neither textual provisions nor cross-sectional evidence for smoke extraction openings for classrooms, corridors, or the central assembly hall are present.
The only document concerning smoke extraction that exists is an installation certificate from 1995 for the two main stairwells. The certificate shows a geometrically effective smoke extraction area of 6.3 square metres and an aerodynamically effective area of 3.78 square metres per stairwell. Following inspection of the actually installed components — one roof hatch and one window per stairwell — there is reasonable suspicion that this area is not achieved in reality.
The school was approved in 1995 under a special construction permit procedure. 31 years later, the essential textual fire safety certifications for the main usage areas are officially unfindable. This is not a records management problem. It is a structural failure in the building permit itself or in its archiving — or both.
V. Fire Brigade Deployment: Reality Check in March 2026
What often sounds abstract in safety assessments became concrete on 24 March 2026: a hazardous materials incident at the school, triggered by the release of irritant gas, forced the fire brigade to ventilate the building. The result was unambiguous and is documented.
The incident commander recorded: the building could not be properly ventilated via the limited window gaps. The fire brigade had to laboriously transport specialised ventilation equipment with long hose lines through a stairwell to the first upper floor to extract the contaminated air.
This is not an indication of a theoretical deficiency. This is a documented deployment in which the structural window restriction impeded emergency response operations. Whether this time loss would have been inconsequential in the event of a fire or a more serious chemical release is a question those responsible must ask themselves.
The city's press office assessed the incident differently a few weeks later: the inadequate ventilation capability posed "no immediate high-risk hazard." This assessment stands in direct contradiction to the documentation of the incident commander and the statement of the Unfallkasse Nord.
VI. Roof Structure: Glulam Beams Without Verified Certificates
The roof over the central assembly hall consists of visible glued laminated timber beams, purlins, and a trapezoidal sheet metal roof package. For load-bearing roof structures over atria with a height of more than seven metres, defined fire resistance requirements apply — generally 90 minutes.
The status report identifies several items in the existing documentation that require verification:
- The structural charring calculation for the timber beams
- The fire resistance class certificates for the purlins and cross-members
- The test certificates for the trapezoidal sheet metal roof package regarding enclosure and thermal insulation
- The fire safety certifications for the structural connection nodes
This is not an isolated finding. The central assembly hall over which this structure hangs is simultaneously the area for which no textual smoke extraction certifications exist in the building permit file, as Section IV documents. Missing fire safety certifications for smoke extraction and an unresolved fire resistance rating of the roof structure thus converge in the same space: the place where the most children are present every day.
The report's wording is cautious — "require verification" — but the direction is clear: there is a need to clarify whether the roof structure over the most-used area of the school would hold long enough in the event of a fire. This question is not answered in the existing documentation.
VII. Compensatory Measures: Testing Instead of Solutions
The administration is not inactive. That should be acknowledged. But it is worth looking closely at what the current measures achieve — and what they do not.
Technical modifications are being tested in a reference classroom (Room 6d): rotating locks on windows, windows with horizontal subdivision, and openable skylights to the corridor for cross-ventilation. On 29 April 2026, bird protection nets were mounted on the electric smoke extraction windows in the assembly hall so that these could in future also be used for regular ventilation. The caretaker ventilates the building daily before lessons begin.
A permanent structural certification for retrofit fall protection is not yet available. The bird protection nets mounted on 29 April 2026 to make the assembly hall smoke extraction windows usable for regular ventilation have an open problem: their impact on the aerodynamically effective smoke extraction area is not documented. The only active improvement measure for air quality could simultaneously reduce smoke extraction performance in case of fire. Whether this is the case is currently unverified.
The caretaker's morning ventilation is a sticking plaster on an open wound. It changes nothing about the window parapets, nothing about the missing fire safety certifications, and nothing about the fact that the fire brigade deployment in March 2026 already demonstrated what happens in an emergency.
VIII. Life-Threatening Risks Listed Under "Any Other Business"
Parallel to the structural chronology runs a political one. The school parents' council had submitted a timely application on the window and ventilation situation to the responsible specialist committee. The administration placed this application in the May 2026 session under the agenda item "Any Other Business" — the last, typically abbreviated item on a committee agenda, under which topics disappear without dedicated debate time.
The committee did not allow this. The elected representatives overruled the administration and ensured that the topic would be scheduled as a fixed agenda item for the session on 16 June 2026. The committee also bindingly demanded the submission of the ventilation protocol and the official statement from the Unfallkasse Nord.
The administration classified a safety issue that the Unfallkasse Nord has linked to the term "negligent homicide" under "Any Other Business." This is not carelessness in agenda management. It is a measure of how the matter is being handled.
Conclusion: Who Bears Responsibility?
A building constructed in 1995 and used daily by hundreds of minors shows, 31 years later, safety deficiencies in seven documented categories. Some of these deficiencies are as old as the building itself. Others became visible at the latest in 2012. The most recent official record dates from 11 May 2026.
What distinguishes this case from an ordinary maintenance backlog is the chronology: the Unfallkasse Nord recommended the retrofit in July 2020. A case officer waited out the summer holidays. The railings were not installed. In January 2026, the department head attempted to declare the matter closed. The Unfallkasse engineer contradicted this the same morning. The department head again declined the retrofit. The parents' council submitted an application. The administration filed it under "Any Other Business."
The question this report raises is not technical. It is political: how long is it acceptable to keep a school building in operation whose fall protection is inadequate, whose fire safety certifications are officially unfindable, whose air quality is documented to cause health complaints, and whose smoke extraction system demonstrably failed in an emergency — while the administration tests rotating locks in a reference room and files safety issues under "Any Other Business"?
The Fachdienst Hochbau is examining. The structural engineers are calculating. The compensatory measures are running. That is better than nothing. But the Unfallkasse Nord has already put in writing what happens if an incident occurs: the public prosecutor will "investigate for negligent homicide." That is not a worst-case scenario from a critic. That is the official assessment of the statutory accident insurer.
A school is not a provisional arrangement. Those responsible for its operation assume a duty of care towards minors — a duty that is not fulfilled by bird protection nets and early morning caretaker shifts.
FAQ
How long have the deficiencies been known?
The fall protection problem and the faulty facade construction became apparent at the latest during renovation work in 2009/2012. The indoor air overcrowding problem is documented in an official memorandum dated 26.02.2026. The notice regarding missing fire safety certifications in the building file is dated 11.05.2026.
Is the school currently open to pupils?
Yes. Ongoing operations are maintained through immediate operational measures, such as morning ventilation by the caretaker. Structural solutions for fall protection and fire safety are, according to the status report, still in the testing and review phase.
How much does it cost to fix the deficiencies?
Rectifying the concealed construction deficiencies from the original build alone has already caused 550,000 euros in construction costs and 50,000 euros in planning costs. Costs for the outstanding measures — structurally certified fall protection, ventilation upgrades, and fire safety certifications — have not yet been quantified.
Which authority is responsible for remedying the deficiencies?
The Fachdienst Hochbau of the city administration of Geesthacht bears operational responsibility. It has commissioned a structural engineer to carry out an assessment and is testing technical modifications in a reference classroom. Political responsibility lies with the competent committee and the city council.
What specifically did the Unfallkasse Nord demand?
The Unfallkasse Nord recommended by telephone on 13.07.2020 the subsequent installation of a 1-metre fall protection barrier in front of the windows. The responsible case officer internally declined. In January 2026, the senior engineer of the Unfallkasse reiterated the demand and noted that a failure to install the protection could be assessed as an avoidable breach of duty of care in the event of damage, resulting in investigations for negligent homicide.
Can parents exempt their children from school because of the deficiencies?
Compulsory schooling remains unaffected as long as the school is officially considered operational. However, parents can submit written statements to the school management, the school authority, and the competent school supervisory authority. The school parents' council has already submitted an application to the specialist committee. This avenue of political influence is currently the most effective.
What do CO2 levels above 1,400 ppm mean for children's health?
Above 1,000 ppm, indoor air is classified as hygienically notable by the Federal Environment Agency; above 2,000 ppm as unacceptable. Values between 1,000 and 2,000 ppm demonstrably lead to reduced concentration, headaches, and fatigue — symptoms documented at the Alfred Nobel School. Children are more sensitive than adults, as their breathing volume relative to body mass is higher.
When will the political decision on concrete measures be made?
The competent specialist committee has scheduled the matter as a fixed agenda item for the session on 16 June 2026, after the administration had initially filed the parents' council application under "Any Other Business." The committee has bindingly demanded the submission of the ventilation protocol and the statement from the Unfallkasse Nord.
Is the architect liable for the deficiencies?
That is a question for a specialist construction lawyer. What is established: the Unfallkasse Nord engineer assessed the disregard of the then-applicable safety regulations (GUV 16.3) as "criminal." Civil law claims against the architect are likely time-barred after more than 30 years. Criminal liability lies, in the Unfallkasse's assessment, with those who have failed to act since 2020 despite knowledge of the deficiencies.
Are there comparable cases at other schools in Schleswig-Holstein?
No publicly available comparative data exists. What sets the Alfred Nobel School apart is not the existence of construction deficiencies as such, but the documented combination of known deficiencies, refused retrofitting, missing fire safety certifications in the file, and a fire brigade deployment that has already demonstrated the consequences in real operation.
