This article details the background and construction of a coal storage circular dome for Indonesia’s largest fertilizer producer, PT Pupuk Kalimantan Timur (Pupuk-Kaltim). Geometrica was selected based on the company's ability to meet Pupuk-Kaltim's very specific logistical and environmental needs.
Domes are surfaces that curve in two directions. The most common domes spring from a circular base and for that we call them "circular domes" at Geometrica, even if their cross-section is not circular. So the term "circular dome" differentiates domes on a circular base from Freedomes® that spring from bases of other shapes.
Vaults are structures that span in one direction only, such as arches or longitudinal cylinders, also known as barrel vaults. Vault spans begin at around 40m and can reach over 100m. Geometrica vaults have been used as sports facilities, transportation terminals, aircraft hangars and for environmental protection.
Many applications require roofs or covers that are flat, or nearly flat. Space frames provide efficient solutions for these requirements. The most common space frame geometries are called "offset rectangular grids", "square on square space frames", or simply "square grids".
But square grids have a couple of characteristics that may limit their use for the longest spans:
Since humans first began congregating in spiritual spaces, they have practiced their faith within vast interiors of inspiring heights. Today is no exception as architects design innovative prayer and assembly spaces.
The first integrated solid waste facility in the Middle East began operation near Mesaieed, Qatar, in October 2011. It uses a Geometrica Freedome® for its roof.
It is an unparalleled honor to receive the Architizer A+ Popular Choice Award, earned through public voting after a three-week campaign, for its façade structure in Fernando Romero's Soumaya Museum. Geometrica received the good news on April 1, 2014. Thanks to all that voted for Geometrica and the Museo Soumaya!
A gridshell's organic shape and column-free space provide unlimited design freedom to architects and structural engineers. These innovative space-frame structures derive their strength from having double curvature in their overall shape.
