The Häring Ensphere dome concept and Saldome salt storage facility
May 2018

Ensphere is a radical departure from traditional structural systems. It is based on the simple concept that any rigid, double curvature dome can be supported directly on the ground, to rise freely over all internal structures and across the expanse of space to be enclosed. Glulam dome structures are built, for example, to store bulk goods. Their design and architecture draw inspiration from nature and are perfected by subtle engineering. The Häring Ensphere dome concept makes it possible to cover even large areas with diameters of more than 120 metres efficiently and inexpensively using the sustainable raw material wood. The dome system provides a unique solution to the bulk storage industry. Besides the beautiful design of the structure, the dome system storage meets the demands of the industry offering a potential free span from 80m up to about 200m. Customers profit from highest volume per-square-meer ratio, optimised logistics and minimum maintenance requirements.

The history of thin-shell concrete dome structures and Zeiss-Dywidag system
May 2018

No history of modern building construction can avoid referring to the Zeiss-Dywidag (Z-D) system. In the history of thin-shell structures, four of the major influences are: Anton Tedesko (1903-1994), who is attributed with much of the success of thin-shell structures in the U.S.; Pier Luigi Nervi (1891-1979), who in Italy gave structural integrity to the complex curves and geometry of reinforced-concrete structures such as the Orbetello aircraft hangar (begun 1938) and Turin’s exposition hall (1948-50); and the Spaniard Eduardo Torroja (1891-1961) and his pupil Felix Candela (1910-1997) who followed his lead.

Pix4D Crane Camera is the first crane solution for 3D construction site mapping
April 2018

Revolutionize the way you collect as-built updates of your site with the Pix4D Crane Camera. Images are automatically collected during normal crane operation, then turned into 2D maps and 3D models in the Pix4D Cloud to be easily analyzed or shared online. The construction industry is fully embracing the concept of BIM, as it provides an efficient way to manage complex projects. A prerequisite for BIM to be used successfully, however, is that the very detailed schedule and build sequences defined by BIM must be strictly adhered to. Regular and accurate site surveys are crucial to achieving this. Although drones are suitable for collecting such site data, they have various limitations. A crane-based camera mapping system offers an alternative and enables the automated capturing of on-site data, both at minimal cost and without interfering with the site. This article explains how a crane camera solution allows project managers to resolve some of the most complex and lingering challenges…

Dougong, 2500-Year-Old Chinese Wood Joints Make Buildings Earthquake-Proof
March 2018

Dougong is a unique structural element of interlocking wooden brackets, one of the essential elements in traditional Chinese architecture. The use of dougong first appeared in buildings of the late centuries BC and evolved into a structural network that joined pillars and columns to the frame of the roof. Dougong was widely used in the ancient Chinese during the Spring and Autumn period (770–476 BC) and developed into a complex set of interlocking parts by its peak in the Tang and Song periods. The pieces are fitted together by joinery alone without glue or fasteners, due to the precision and quality of the carpentry.

The Old Fashioned Milk Paint is a natural chemically safe and environmentally friendly paint
March 2018

Milk paint is a nontoxic water-based paint. It can be made from milk and lime, generally with pigments added for colour. In 1974, after much experimentation, The Old Fashioned Milk Paint Co. recreated an old Milk Paint formula to provide an authentic finish for the primary business of building reproduction furniture. Since then the company has sold paint to professionals who are either restoring original Colonial or Shaker furniture, making reproductions or striving for an interior design look that is both authentic and beautiful. Milk Paint is now gaining an even wider usage because it contains only ingredients that are all-natural and will not harm the environment. Authentic real milk paint is truly a "green paint" that comes in 20 colours.

Cuomo Bridge after former New York Governor Mario Cuomo, is a twin cable-stayed bridge being built to replace the original Tappan Zee Bridge over New York's Hudson River. The Tappan Zee Bridge, officially named the Governor Mario M. Cuomo Bridge after former New York Governor Mario Cuomo, is a twin cable-stayed bridge being built to replace the original Tappan Zee Bridge over New York's Hudson River. The new twin spans will be located to the north of, and roughly parallel to, the existing Tappan Zee Bridge, crossing the Hudson River in a parallel east-west direction.

Mjøstårnet, world's tallest timber tower to be built in Norway by Moelven
February 2018

Moelven is responsible for one of the current claimants of the world record for the tallest timber building, "Treet" in Bergen, at 51 meters tall. However, the contractor’s latest project Mjøstårnet is set to reach an even taller height of 81 meters. The Norwegian contractor HENT AS is building the Mjøstårnet project for AB Invest. Moelven Limtre AS is HENT's turnkey subcontractor and will supply glulam, Kerto® and cross-laminated timber for the tower structure. Mjøstårnet will have wood-based floor elements in the bottom ten storeys, using Moelven's Trä8 system. The installation takes place from September 2017 until May 2018.

Siam Research and Innovation Company is developing innovations to push the limits of 3D printing in construction
February 2018

The "Triple S” represents a surface transformation on the human scale using a function of the suitable size of printing nozzle compared to the pattern scale design to formulate a new surface transformation to function - the most sophisticated design method in architecture in this 3D printing work. Siam Cement Group, the most significant cement and building materials company in Southeast Asia, has announced its latest construction 3D printing project, called "Triple S." The Thailand - based company says the new project marks a “new evolution in 3D printing.” Siam Research and Innovation was established in 1991, and currently, it is located at Kaeng Khoi, Saraburi (130 km north of Bangkok). It's one of the subsidiary companies under SCG Cement - Building Materials. Its primary responsibility is to conduct research and development of new products and services related to cement, mortar, concrete and refractories.

What if all of the material used in buildings could be recycled into a new type of construction material?
February 2018

Every year, more than 530 million tons of construction and demolition waste like timber, concrete, and asphalt end up in landfills in the U.S.–about double the amount of waste picked up by garbage trucks every year from homes, businesses, and institutions. The Cleveland-based architecture firm Redhouse Studio, led by architect Christopher Maurer, has developed a biological process to turn wood scraps and other kinds of construction waste like sheathing, flooring, and organic insulation into a new, brick-like building material.

Al-Khazneh, one of the most elaborate temples in the ancient city of Petra
February 2018

Petra means "rock" in Greek, fitting for a town carved out of sandstone desert cliffs. It is located about three hours south of Amman, the capital of Jordan, and was founded by a nomadic Arab tribe known as the Nabataeans several centuries before Christ's birth. Nabatean architecture refers to the building traditions of the Nabateans in Jordan. It includes the temple and tombs of Petra in the sandstone cliffs of Jordan’s Negev desert. The style appears a mix of Mesopotamian and Hellenistic (Greek) influences. Much of the surviving architecture was excavated out of rock cliffs. So the columns do not support anything. Ceramics and coins were also part of the culture. In addition to the most famous sites in Petra, there are also Nabatean complexes at Obodas (Avdat) and residential complexes at Mampsis (Kurnub) and a religious site of et-Tannur.

London's Brutalist style: Balfron and Trellick Tower residential buildings
February 2018

The term "brutalism" was originally coined by the Swedish architect Hans Asplund to describe Villa Göth in Uppsala, designed in 1949 by his contemporaries Bengt Edman and Lennart Holm. He originally used the Swedish-language term nybrutalism (new brutalism), which was picked up by a group of visiting English architects, including Michael Ventris. Brutalist architecture flourished from the 1950s to the mid-1970s, descending from the modernist architectural movement of the early 20th century. The term originates from the French word for "raw", as Le Corbusier described his choice of material béton brut, meaning raw concrete in French.
