How and for whom do I enjoy working?

I do not wish to make my clients dependent upon me. Instead, I wish to remain mobile and independent myself. Therefore, the focus of my work is on protecting my clients’ independence and ability to act.
“Reliability is non-negotiable” is my creed and the basis of my work ethic.

My clients are companies that appreciate collaborating with me as an equal, notwithstanding the pressure caused by competitors and regulatory requirements.

What services do I provide?

Engineering Consultancy:

New construction, reconstruction, seminars as well as communication between the operator, the building contractor and the relevant government agency.

Quality Certification:

External creation of test reports pertaining to the correct execution of refurbished or newly built vessels or drainage systems, e. g., potable water tanks or secondary containments for water-polluting substances.

Testing of AwSV-Plants:

For example storage tanks, filling areas and secondary containments. Test criteria are the German Water Resources Act (WHG § 62), the Ordinance on Installations for the Handling of Substances Hazardous to Water (VawS) and the Technical Rule for Substances Harmful to Water (TRwS).

Testing of Light Liquid Separators and Grease Separator Systems:

Test bases are the German industry norms: DIN 1999-100, DIN EN 858-1/2, DIN 4040-100, DIN EN 1825-1/2, DIN EN 1610 and DIN 1986-30.

Leak Tests on Large Containers:

In the areas of AwSV (German Ordinance on Installations for the Handling of Substances Hazardous to Water) and potable water, with proprietary measuring systems, e. g. for retention basins, waste-water processing plants, biogas plants and potable water containers.

Zalfen-Test-System in Operation

The Time-Capsule Principle

The concept of a time capsule is widely known. Items and information materials such as letters, newspapers and coins are stored within a durable container, thus protected from the environment. They are intended to endure many years before being recovered in the future. The contents are meant to give future generations an idea about life in the past. Some time capsules do not only contain contemporary documents, but also specific explanations or instructions. Such time capsules are not hidden, but may, for example, consist in a walled-in metal box carrying a visible intended opening date.

From the Idea to the Principle

In order to render my work as effective and valuable as possible, I apply the afore-mentioned idea to two problems frequently encountered in large and medium-sized enterprises, viz inadequate documentation, and a lack of knowledge about existing plants.

My Focus: Maintaining the Corporate Ability to Act

I take stock of measures undertaken in the past and thereby create a basis for evaluation that enables companies – independently of their own data inventories and employees – to make decisions on current and future developments. In the process, all services are rendered and documented in such a manner that the critical information is always available, irrespective of the circumstances, at any time including the distant future, just as if it were inside a time capsule.

Analyse, Test, Document

In order to obtain a comprehensive picture, I examine any plans and documents that still exist, interview employees and analyse the plants in question.
The culmination of my work is a comprehensive report and specific recommendations for action. Further information on the process involved in the “Time-Capsule Principle” is available via e-mail upon request.
