Nybruket Gallery Located in one of the old factory buildings of
Kistefos Træsliberi, Nybruket Gallery was another old wood pulp mill established in 1896. Similar to the first pulp mill, this mill was also fully equipped and intact, contributing to the park's industrial heritage. Before the newly installed museum by
BIG, Nybruket was the building where all of Kistefos' seasonal exhibitions were held. Now, smaller or secondary exhibitions are held at Nybruket in their Art Hall. Kistefos was in need of a bigger, more modern museum to accommodate their ever growing collection of artworks, and there was also a need for a second bridge to complete the circulation of the park and allow visitors to explore more efficiently. The winning entry, submitted by BIG, combined both aspects into one structure, proposing a unique bridge-like building spanning across the Randselva river with a twist in the middle. The building was called a "hybrid of architecture, infrastructure and sculpture" and is intended to serve as an attraction of the park in of itself. BIG incorporates the twist skilfully into the 14000 square-meter building, accounting for the difference in elevation of the riverbanks on either side, the 90-degree twist in the middle allows for the width of building to be placed on the lower riverbank while the length is placed on the higher, artistically accommodating for Kistefos' natural landscape. team also contributed to this project. They helped to realize specialised construction and design elements of the facade and roof.Additionally, it creates an array of spaces, allowing for two to three stacked floors in the south, lower riverbank, and a floor-to-ceiling horizontal gallery in the north, higher riverbank. The large horizontal gallery can be used for sculptures and large installations, while the smaller vertical galleries are used for media, paintings, and sculptures, and also holds an information center, museum shop, and other facilities. The glazed-glass sides of the museum follow the warping of the twist, creating a side-lit space at the northern, which provides views of the old pulp mill further up along the river, sky-lit space at the southern part of the building and a dark gallery on the lower level. The engineering team had a challenge of converting the complex geometry from the architectural model to an engineering model complete with building calculations. The issue was solved using
Grasshopper, visual programming application, for the conversion to a
Tekla model, a modelling software, which is compatible with the calculation and structural analysis software
Robot. Assembly of the bridge was another challenge, as it required a sizeable interim bridge to support the museum bridge during construction. The interim bridge had to be of suitable design and assembly to give sufficient stability and enough working space to mount the steel components and aluminium and glass facades. A full-scale trial assembly of the twisted bridge-part exposed no issues that could not be corrected to avoid costly modifications on site. Furthermore, as none of the individual pieces were right-angled and there were no angular repetitions or fixed points on the bridge, the use of
3D modelling was necessary to ensure the complex geometry of the structure corresponds to the design models. With the structure made entirely of steel,
secondary steel was also designed for use as standard ceilings and walls, to cover both inside and outside of the building, and this smaller project took approximately 20% of the total design time. == Works ==
