Senior Calculator (Maarssen, NL)

Ballast Nedam Parking

Senior Calculator Parking, Marine & Civil

Your challenge

To strengthen our tender teams, we are looking for a Senior Calculator who takes responsibility for the financial part of our offers. You are proactively involved from the preparation / analysis and interim contract changes to the actual costs and evaluation. You draw up prices, enter into discussions with subcontractors, request quotes and cast your critical financial view on the design. Part of your work is also monitoring market prices and quotes from materials and partners, for example.

In this way you become responsible for the calculation of the correct quotation for our projects within Parking, Marine & Civil. You take into account all aspects required to arrive at the most suitable estimates and budget. In doing so, you weigh up the risks that stand in the way of the financial success of the project and you advise on the costs of control measures. Ultimately, we can offer a competitive but fair and realistic price with tenders or quotations.

You work on a large project for a few months but it also happens that you work on several smaller offers at the same time. For you, the regulations regarding tenders according to the UAV-gc have no secrets. Experience with BIM and Lean are welcome.

Your profile

  • You have completed the HBO degree in Civil Engineering or another relevant study;
  • You preferably have at least 5 years of experience in the calculation or you are prepared to invest in your knowledge level through training;
  • You become enthusiastic from the numerical side of the profession and you enjoy searching for better, cheaper solutions for technical challenges;
  • You are accurate, communicative and customer-oriented;
  • You are competitive, initiative-rich and resourceful;
  • You enjoy working as a team on the winning offer

The location of the position is at the office at Ballast Nedam PMC in Maarssen. There and at our head office in Nieuwegein you will find sparring with colleagues and colleagues.
