Rolsch Assetmanagement

"Our method provides insight in risks
and assists in lowering costs"

About Rolsch

For several years Rolsch Assetmanagement has been engaged in the infra-world concerning waste water and drinking water. We specialized in this field because of the relevance on our daily life of collecting waste water and supplying drinking water in combination with the complexity of its maintenance. Over the years our consultancy activities have been expanded to include the development of specialistic assetmanagement software. This software assists our customers in the management of their sewer or drinking water network.

Assetmanagement

Assetmanagement

Using our specialized software we are able to apply assetmanagement in a practical way. Based on client specific data the current performance and risks of the assets are investigated. Guided by a desired quality level we determine which assets are to be selected for an effective maintenance plan.

Optimun

Optimum

Using advanced algorithms we calculate for each asset a risk based business case. This method allows for an optimal balance between performance and costs. The calculation is done on asset as well as on business level.

Kostenbesparing

Cost reduction

Using our method asset are being replaced based on performance and cost efficiency for the entire network, in contrast to the often used cyclic replacement of assets. Experience shows that up to 30 % reduction of the current budget is achievable without compromising the desired performance of the waste water or drinking water system.

Rolsch Assetmanagement rationalizes maintenance. Using our software your assets are being maintained risk-driven, based on advanced algorithms.

The Team

Our team consists of a broad selection of professionals.

Ronald Laverman

Consultant

Is maintenance strategist and interested in sustainable business with both the customer and the people that work with us. I think it's important that everyone feels personally involved and responsible in a challenging and complex environment like ours.

Background After my HTS education in Amsterdam I quickly enrolled in the engineering world. It struck me that maintenance of existing equipment was often neglected while the financial consequences to keep systems running was quite large. A solid base for the usefulness and necessity of the rather expensive maintenance activities almost always lacked. At that time decisions based on gut feelings seemed adequate, but very difficult to quantify. In 1999 I was assigned the task to examine and possibly improve the maintenance strategy of one of the largest drinking water companies of the Netherlands (Vitens). This formed the foundation of our current quantifiable maintenance management philosophy.

Private Together with my wife we run a family with three great kids. In the weekends I can be found along the line of sports fields or cycling a firm trip on a mountain bike.

Hajo Molegraaf

Hajo Molegraaf

Consultant / Software Engineer
Owner

Has studied experimental physics at the University of Groningen, followed by a PhD research on quantum mechanics and high temperature superconductivity. After that he has done research on nanotechnology and magnetism at Yale University, University of Geneva and University of Twente. He has a lot of experience with data analysis and development of mathematical models to describe the measurements. He often developed the necessary software for the analysis himself.

After he came into contact with Ronald he started working on the analysis and modeling of pipe networks, initially part time and later full time. The application of statistical analysis on pipe data and the development of new algorithms for asset management, together with the ability to create a user friendly software tool, has led to a product that gives interesting results.

Richard Hinkamp

Software Engineer

Has been raised on the internet. After I created my first website in 1995 I studied HBO informatica. Then after succesfully running an Internet company for 14 years, I am now responsible for MapKit. Most of the time I am working on the development of new functionality for MapKit. Besides developing I like to discuss with our customers the needs they have, in order to improve the software and have it match as good as possible to their way of working.

Besides my work I spend as much time as possible with my girlfriend and my two children. In my spare time I like doing basketball; I like to throw a ball and am a member of the board for 10 years.

Peter Wonink

Peter Wonink

Consultant

Is always looking for new ways to further improve existing solutions. Often a solution is found by getting inspiration from adjacent areas. Risk based asset management of drinking water systems was in this way found to be perfectly applicable to sewage systems and pressurized waste water systems. This formed the foundation for the development of Rasmariant-Sewer: An innovative ICT solution that makes asset management for waste water systems practically applicable.

After his studies at TU-Delft Peter has worked for several leading engineering companies in the Netherlands in the field of water system maintenance and water supply chain maintenance, including many years as head of a department.

Peter is in many ways actively connected with developments in his field. As the secretary of NSTT, division pipeline renovation, he promotes trenchless technologies. As a member of the NEN committee wastewater techniques he guards the interests of sewer community and he contributes to the formulation of new standards. For RIONED he regularly provides courses.

Peter is married and has four children.

Rasmariant

Rasmariant

Rolsch puts the drinking water or waste water network from your municipality or company under the microscope. Visual CCTV inspections or recorded pipe failures provide information on possible cracks, ground water in pipes, barriers and intruding soil. With Rasmariant, our software program developed by Rolsch, we provide you with more insight in the consequences of problematic pipes. In short: With Rasmariant we make the step from existing data to new information. When does a pipe require renovation in order to guarantee its proper working? And which pipe in your company gives the highest return upon replacement?
