43 glulam buildings in two months: record construction times for the pavilions at the Expo 2015

Cluster CL1

In only two months, Rubner Objektbau constructed 43 special turnkey buildings to be included in the cluster pavilions, which were conceived as multifunctional exhibition areas for approx. 70 countries.

1,410 m³ of glued laminated timber, 6,000 m² of roof panels, 18,000 m² of wall panels, and 5,050 m² square ceiling tiles were made from Xlam. A team of experts completed the assembly of all these in record time.

The pavilions stand for four major themes: “Bio-Mediterraneo” (Bio-Mediterranean), “Isole” (Islands), “Zone Aride” (Arid Zones), und “Cereali e Tuberi” (Cereals and Tubers). Each area was designed individually and given the characteristics of the region it represents. A multifunctional common area complemented the clusters.

The “Bio-Mediterraneo” cluster included twelve exhibition buildings, three technical buildings, and four kiosks grouped around a pergola-covered square. The exhibiting countries were Albania, Egypt, Greece, Lebanon, Serbia, Malta, Montenegro, Tunisia, and San Marino.

The “Isole, Mare a Cibo” cluster was composed of two exhibition buildings and a technical building as well as a tasting area and a roofed area with bamboo cane elements for sun shielding. It represented all those small countries whose territories are islands and archipelagos. What they all have in common is their ocean-based ecosystems (Cape Verde Islands, Maldives, Comoros, Caribbean).

The “Zone Aride” area introduced visitors to a desert landscape consisting of eight modular exhibition buildings and a technical building grouped around a roofed square. This cluster was dedicated to countries struggling with desertification: Eritrea, Senegal, Mauritania, and Palestine, among others.

Seven modular jute-lined buildings, a central aisle shaded by sun shields, and a roofed square with a kitchen building formed the fourth cluster, “Cereali e Tuberi.” It was the representation of a valley with cereals and tubers from all around the world, e. g. from Bolivia, the Congo, Mozambique, and many other countries.

The following material was used to construct the timber halls:

  • 1,410 m³ of glued laminated timber,
  • 6,000 m² of roof panels,
  • 18,000 m² of wall panels,
  • 5,050 m² of Xlam ceiling elements.
