    Exterior of the Bristol Myers Squibb building.

    The CAR T cell therapy production center at the Leiden Bio Science Park (LBSP). Leiden in the Netherlands will be the biopharmaceutical company’s first cell therapy facility in Europe and the fifth in the world. CAR T cell therapy is an immunotherapy in which a patient’s white blood cells are reprogrammed so that they are able to recognize and fight cancer cells.


    The client required hygienic door solutions for its new cell therapy manufacturing plant.


    Dortek doors are designed to meet CGMP requirements and have a seamless gel coat finish which is non absorbent and easy to clean. These doors are high performance and low maintenance making them ideal for pharmaceutical and biotechnology applications. Dortek provided fire rated hinged doors to meet EN 1634-1 and local Netherlands fire requirements.

    Dortek supplies doors into a 50mm panel wall system. The client requested a flush integrated magnet. We developed a solution to provide the flush magnet that integrates into the frame head. The Dortek katro frame enables very quick door and frame installation time for the contractor, as the doors are factory fitted with ironmongery and integrated magnetic locks, but also the frame and door system can be installed later in the project meaning more flexibility during the erection of the panel walls and better quality control. This detail is now being implemented in many of our other projects as the standard magnet detail for 50 and 60mm wall panel systems.

    Many of the Dortek doors were interlocked, which included flush integrated mag locks into a 50mm frame system, traffic light and door activation where the doors were automated, and connection to the BMS (Building Management System).
