At CERN, the European Organization for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe. Using the world's largest and most complex scientific instruments, they study the basic constituents of matter - fundamental particles that are made to collide together at close to the speed of light. The process gives physicists clues about how particles interact, and provides insights into the fundamental laws of nature. 

Introduction

You will undertake concept and preliminary design and prepare and implement design and construction contracts for the detailed design and construction of the civil engineering required for the new FCC Injection Complex to be constructed at the CERN Site in Prevessin, France, subject to FCC project approval. The civil engineering consists of a cut and cover reinforced concrete structure over 1km long and a series of surface buildings to house ancillary technical infrastructure
