February 2016 Main article 3d printing of functional structures Lustrum edition Celebrating the past, into the future, To infinity Year 34 | Edition 1 Talented and ambitious electrical engineers With a workforce of more than 1000 specialists worldwide, we are part of the top ten Dutch engineering and consultancy firms. We have six of- fices in the Netherlands, with our main office in Deventer, and ten offices abroad. Our employees work on a variety of projects in the fields of infrastructure, water, the environment, spatial development and construction. We are for instance working on eminent projects like the Botlekbrug at Pernis, Spoorzone Delft, the ultrapure water factory in Emmen, and the design of the wastewater treatment plant in Amsterdam-West. Abroad we are contributing to for instance water projects for oilfields in Kazakhstan and drinking water facilities in Ghana. To be able to succesfully fulfill these projects, our employees have a background in civil, electrical, mechanical or building engineering or are educated in the field of environment. As an electrical engineer you will work on challenging projects like the (functional) design, control and pro- pulsion of constructions like pumps, (movable) bridges, locks, sewage and drinking water treatment plants, oil and power generation plants. The role you have in these projects will vary from feasibility and preliminary designs to guiding the construction. Innovation is an important part of your job. You will be working in multidisciplinary teams. Your main location can be Deventer, Breda or Utrecht. As an engineer at Witteveen+Bos you are constantly searching for new challenges. You will be cooperating with young colleagues and will be given the chance to explore on innovative solutions. We will support your development with both professional and personal studies. Would you like to be part of our team? Check our website www.witteveenbos.nl for our vacancies as well as our internships and thesis assignments.

This might be partially due to me, as the trees were of a nice Scintilla-red colour when I started writing this presidential note, but now that I am finishing it, there are only a few leaves remaining on the rather bare trees. But as the trees turn bare, my collection of memories and stories from my board year only seem to grow. When you read this note, I might al- chuckle now and then.
