Boskalis Westminster is looking for a Cost Estimator to join our small, dynamic Estimating team. You will be responsible for developing innovative and sustainable working methods to deliver a wide range of marine projects, including the maintenance and capital dredging of ports and harbours, coastal protection works and land reclamation. Working within our team you will be involved in understanding vessel productions, cost calculations and the preparation of the tender submission documents.

We have a proven track record of supporting personal and professional development, allowing you to grow within our organisation. Full training will be given, with opportunities to study for ICE qualifications as well as internal and external courses specific to our industry. Whilst the role is predominately office based, travel to meet clients and visit projects is expected, with potential opportunities for overseas travel.

We recognise that we are a specialist contractor and whilst previous marine experience would be beneficial, it is not a requirement.

Main Tasks

  • Analysis of client tender documentation.
  • Working with the wider Boskalis organisation, ensuring all the elements required to complete a tender are correctly managed and understood.
  • Development of cost estimates and written quality elements, including work methods.
  • Completion of tender documentation.
  • Following up submitted tenders with clients and involvement with any post tender queries / negotiations.
  • Supporting the project team once the works have been awarded and are underway

Required Knowledge and Experience

A good degree, ideally in Civil Engineering or with a marine basis is required. We recognise that we are a specialist contractor and whilst previous marine experience would be beneficial, it is not a pre-requisite. We are looking for an enterprising future colleague who is comfortable working with numbers and able to develop technical documents clearly and concisely. Working within a team, at times to challenging deadlines, is a given as is the ability to communicate clearly with clients and senior management.
