Project Description

Post-tension works for BRUSK: An Ambitious Museum Project in Bruges

Bruges, renowned for its rich history and vibrant tourist scene, is set to elevate its cultural offerings with the construction of BRUSK, a state-of-the-art exhibition hall. This ambitious project underscores the city authorities’ commitment to fostering an innovative and contemporary art policy within the heart of the historic city centre.

The design and development of BRUSK are collaborative efforts involving prominent entities such as developer CIT Red and the design team led by architects Robbrecht en Daem Architecten and Olivier Salen at Ney & Partners.

CIT Blaton is carrying out the construction, ensuring the project benefits from top-tier expertise.

Strategic Location and Flexible Spaces

Located on the Garenmarkt, adjacent to a new park, BRUSK is designed to integrate seamlessly into the urban fabric of Bruges. The exhibition spaces are strategically separated by a public passageway known as Scala Grande, providing a unique blend of accessibility and grandeur. These spaces, measuring 40 x 40 meters and 20 x 40 meters, offer the flexibility to host a variety of exhibitions and events simultaneously. The design emphasizes natural light from the north side and boasts an impressive height of 13.75 meters, enhancing the spatial experience for visitors.

Post-tensioned slabs and beams – addressing Unique Design Challenges

Interspan was entrusted with the critical task of designing and constructing the post-tensioned slabs and beams that form the structural backbone of BRUSK. This 3,000 square meter post-tensioned scope posed several unique challenges:

  • Heavy-Load Slab Requirements: The slab was designed to withstand a dead load of 3.0 kN/m² and a live load of 25.0 kN/m², with additional structural demands to support a steel framework.
  • Strategic Structural Design: The 700mm thick slab incorporated openings to conceal ventilation and mechanical ducts, balancing structural integrity with aesthetic requirements.

Operational Achievements

Interspan navigated these complexities with precision and innovation:

  • Reinforcement Systems: The implementation of multi-strand (12-strand) and mono-strand (4-strand) bonded systems effectively reinforced the slabs.
  • Complex Installations: Challenges posed by tendons, internal openings, embedded steel anchors, and mechanical components were expertly managed.
  • Coordination Excellence: Seamless coordination with other project teams ensured the integrity of the post-tensioned system without conflicts between tendon layouts and mechanical ducts.

Engineering Excellence and Innovation

The successful completion of the BRUSK Museum project stands as a testament to Interspan’s commitment to delivering innovative engineering solutions and superior construction outcomes. Extensive expertise in post-tensioning technology, combined with a collaborative approach, has resulted in a structure that not only meets but exceeds the stringent demands of modern architectural design.

A Collaborative Approach

BRUSK is more than just an exhibition hall; it is a symbol of Bruges’ forward-thinking approach to cultural development. Through the collective efforts of architects, engineers, and builders, this project showcases the power of innovation and collaboration in creating spaces that inspire and engage.

As construction industry professionals, we can gain valuable insights from the BRUSK project’s challenges and achievements and apply these lessons to future endeavours in architectural and structural excellence.
