Located in the Leiden Bio Science Park West in the Netherlands, Nexus Leiden comprises 9,100 square meters over four large floors, housing laboratories and offices to support the critical work of life science, health and pharmaceutical companies. With its construction site nestled in a busy science park, modular construction techniques were employed to minimize the timeline, space and onsite disruption of the building’s construction. Working closely with the project’s main contractor, Dura Vermeer Bouw Zuid West, and concrete supplier Holcon BV, Mammoet supported the assembly of the building’s shell structure, which was made of precast concrete and steel. A centerpiece … Read more
