Occupational safety for engineering and planning offices
Engineering and planning offices calculate and design at the desk. Measurements and sign-offs, by contrast, take place where the installation is: in a hospital plant room, for example, or in a client's production hall. On site the operator's rules apply. The risk assessment for your own employees is still yours to produce, and it has to cover these site visits explicitly.

Engineering offices in the field: working in other operators' plant
An engineering office works in two places that have little in common. At the desk, staff read plans on several screens and on paper. In the field, your employees work in installations and on sites where someone else sets the house rules.
Where your employees work on a client's premises, the Occupational Health and Safety Act requires both employers to cooperate: they inform each other about the hazards and agree on protective measures (section 8 ArbSchG). In practice that means asking about access rules, the protective equipment required and any particular hazards of the installation before the first visit, and recording the operator's on-site briefing. Without that record, it is hard to show after an accident that the coordination took place.
For measurements carried out by one person alone in a remote installation, DGUV Information 212-139 describes the options for raising an alarm, from agreed check-in calls to a personal emergency signal device. The risk assessment decides which solution is sufficient. A sign-off in an occupied office building is assessed differently from a measurement someone takes alone in a pumping station at the weekend.
How engineering and planning offices are classified under DGUV Regulation 2
| Item | Engineering and planning office |
|---|---|
| Accident insurance institution | VBG. Its risk tariff position for engineering and architecture also takes in structural engineering and surveying offices |
| Planning department within an industrial company | The accident insurance institution of the main business (section 131 SGB VII). The membership notice is binding |
| Economic sector | WZ 71.1 architectural and engineering activities |
| Support group under DGUV Regulation 2 | III: above 20 employees (Annex 2) 0.5 hours of basic support per employee and year, shared between specialist and occupational physician, at least 20 per cent each. Company-specific support comes on top |
| From the first employee | Risk assessment, safety training, first-aid organisation, appointment of an occupational safety specialist and an occupational physician |
| Up to 20 employees | Annex 1 of DGUV Regulation 2 with no fixed support hours |
| Above 20 employees | Occupational safety committee meeting once per calendar quarter (section 11 ASiG) |
| Up to 50 employees | Unternehmermodell permitted as an alternative. More than 50: standard support |
| From 50 employees in an office | Safety officers (section 22 SGB VII, since 29 May 2026) |
All employees count, whether they work in the office or in the field, including technical draughtspeople, working students and trainees. Part-time staff count proportionally towards the threshold of 20: up to 20 hours a week as 0.5, up to 30 hours as 0.75.
What matters in the risk assessment of an engineering office
- Site visits in other people's plant. For measurements, inspections and sign-offs the operator's rules apply, not your own. Access, on-site briefing and the required protective equipment have to be settled in advance and belong in the assessment.
- Lone working in the field. Site visits frequently happen alone. A binding arrangement is needed for who is where and at what point a missing check-in is noticed.
- Several screens and printed plans. Plans are read side by side, often on two or three monitors plus a printout. That shifts the focus to monitor arrangement, viewing distance and lighting.
- Commercial areas of manufacturing businesses. Where the planning office is part of a manufacturing business, office and plant areas have different hazards. They must not be merged into a single assessment.
Survey teams and inspectors working on public roads also need high-visibility clothing and a measuring point protected from passing traffic. The assessment should give this work a section of its own.
What a walkthrough of an engineering office brings to light
The office area rarely stands out: the workstations are well equipped and the findings usually concern monitor height and glare from window fronts. Field work is where things surface. What is regularly missing is a list of recurring site visits, an arrangement for protective equipment, and evidence that employees were briefed on the operator's rules before their first visit.
Safety training in an engineering and planning office
Alongside the office topics a field-work block is needed: conduct in other people's plant, handling your own protective equipment, securing your position when working alone, and the reporting route after an accident while out. Where measuring instruments, ladders or access equipment are used, operating them belongs in the training too, not in an operating instruction nobody reads.
Ladders carried in a company car have to be checked visually for obvious defects before every use. If they are exposed to influences that can cause damage, they also need recurring inspection by a competent person (TRBS 2121 Part 2); the risk assessment settles whether frequent transport counts as such an influence. For electrical measuring instruments and chargers, use the Test-interval calculator (DGUV Regulation 3).

Frequently asked questions
Which employers' liability insurance association covers engineering offices?
For independent engineering, structural and surveying offices, the VBG. If the planning function is a department of an industrial company, it belongs to that company's insurance association, because the institution covering the main business is responsible for every part of the same enterprise. Your membership notice says what applies to you.
Who briefs our engineers on the client's plant?
The operator has to make sure that staff of other firms working on its premises have received appropriate instructions (section 8 (2) ArbSchG). Your own safety training still applies alongside that. You prepare your staff for work in other operators' plant in general; the operator covers the hazards of its own installation.
Is a mobile phone enough when someone takes measurements alone?
That depends on the hazard. Where it is low, an agreed call-back at fixed times may be enough. Where it is higher, meaning an accident could leave the person unable to call for help, DGUV Information 212-139 describes technical solutions such as personal emergency signal systems. The decision and the reasons for it belong in the risk assessment.
