New Liverpool landmark is defined by Jura limestone

The new Museum of Liverpool in the U.K. is being touted as a “global benchmark for museums of its kind.” Scheduled to open in 2011, the building’s design features 70,000 square feet of Jura limestone from Vereinigte Marmorwerke (V.M.) Kaldorf of Kaldorf, Titting, Germany.

When it is finally completed in the early part of 2011, the new Museum of Liverpool in the U.K. represents an opportunity for the city to be noticed on an international level, and this fact has not been lost on the museum’s trustees, who expect the facility to set “the global benchmark for museums of its kind.” To help meet these lofty goals, the museum is being outfitted with a striking design that includes Jura limestone as a key element.

Constructed at a cost of more than $116 million (72 million British Pounds), the Museum of Liverpool is the largest newly-built national museum in Britain for over a century. It is also the world’s first national museum devoted to the history of a regional city, reflecting Liverpool’s “global significance” through its unique geography, history and culture.

The design by the architects at 3XN called for the stone panels to be cut into a range of shapes, including elongated triangular shapes for much of the facade. Much of the stone cladding was installed in a system that allows panels to angle outward from the building - creating a three-dimensional pattern.

The architect for the project is 3XN of Denmark, and the firm released a design statement that reads: “The new Museum of Liverpool ambitions to become the world’s leading city history museum, showcasing social history and popular culture and will look at Britain and the world through the eyes of Liverpool. It is estimated that the new museum will attract at least 750,000 visitors on a yearly basis, and that Liverpool, with the museum as a symbol of Liverpool’s ongoing regeneration, will be elevated into the front rank of European tourist destinations, as well as providing a brilliant place for local families to find out about their own history.”

The museum is located at a noteworthy site within Liverpool, and with this in mind, 3XN’s design needed to be distinctive while also fitting into the overall context of the area. “Located at the UNESCO World Heritage Site between the Albert Dock and the Pier Head, and next to a row of prominent historic buildings dubbed ‘The Three Graces’ the museum building is conceived as inclined or elevated platforms, gradually forming a sculptural structure,” stated 3XN. “Fully accessible, it will contribute to the public promenade flow along the Docks. Situated at the Pier Head, the museum will be visible from both the river and the city.”

Use of stone

The exterior of the Liverpool Museum is characterized by geometric panels of Jura limestone from Germany. The material was quarried and processed by Vereinigte Marmorwerke (V.M.) Kaldorf of Kaldorf, Titting, Germany - in the heart of Bavaria’s stoneworking region. Waldemar Ruff of V.M. Kaldorf explained that the Jura Beige limestone was taken from “Layer 17” of the quarry, which is part of the upper section of the site. The stone was furnished with a “Kratzschliff” (scratched) surface finish, and V.M. Kaldorf supplied a total of 70,000 square feet of material for the project.

The design by the architects at 3XN called for the stone panels to be cut into a range of shapes, including elongated triangular shapes for much of the facade. According to Ruff, these triangular pieces required special attention during fabrication. “The technical execution in our factory to do the special diagonal cuts at the long edges [were a challenge],” he said.

In addition to the triangular pieces, the stone panels at the base and around the large window openings was specified in a rectangular format.

Installation details

The contractor for the Liverpool Museum is Pihl Galliford Try - a joint venture of E. Pihl & Søn A.S. of Lyngby, Denmark, and Galliford Try of Middlesex, England. “The facade is covered with natural stone, interrupted by some large glass panels, which eliminates the boundary between indoors and outdoors,” explained architect Mogens Hedegaard Andersen, head of the Pihl Architectural Design Office. “The [joint venture] project includes the construction of works consisting of concrete foundations, steel structures and natural stone facade cladding as well as electrical and plumbing. The design supply and installation of natural stone facades is being performed by the Pihl Architectural Design Office and the Pihl Natural Stone Department.”

Pihl reports that it has used Jura stone on a number of projects in Northern Europe, and it has proven to be resistant to environmental factors such as frost, salt, pollution and other elements. The stone was specified in a range of thicknesses, primarily 3 and 4 cm.

Much of the stone cladding was installed in a system that allows panels to angle outward from the building - creating a three-dimensional pattern. The resulting “shadowing effect” adds life to the facade, as the color and tone of each stone panel will vary depending on its placement on the wall.

A range of installation techniques were used for affixing the stone to the building. For the protruding sections at the upper portions of the facade, the stone pieces were assembled onto steel trusses, which were then installed over a steel frame system. Meanwhile, the stone at the base of the building was installed over a concrete backup wall. Finally, the vertical stone panels around the large window openings were installed on a steel rafter system.

The steel framing beneath the stone cladding contains 2,100 tons of structural steel, and the steel structure allows the museum’s largest exhibition spaces - which are 130 feet long x 92 feet wide - to be column free, ensuring that the galleries and public spaces are maximized.

A worldwide attraction

According to the Board of Trustees, the Museum of Liverpool will attract more than 750,000 visitors per year, including 100,000 learning visits, and it will provide at least 500 construction jobs and 73 direct permanent jobs. “The new Museum of Liverpool will be one of the world’s leading city history museums, setting the global benchmark for museums of its kind and raising social history as a museum discipline to an international scale,” stated the Board. “The museum will demonstrate Liverpool’s unique contribution to the world and will showcase popular culture while tackling social, historical and contemporary issues.”

Construction of the museum began in January of 2008, and the project will be fully completed in early 2011.

A computer rendering was made for each assembled component, and the stone had to be fabricated to precise specifications.
