Construction

The video documents the construction and testing of the longest single-span FRP composite bridge of its kind in the world. Made by Polish company Mostostal Warszawa in 2015 the bridge was part of the Com-bridge research project, co-financed by the National Centre of Research and Development’s programme supporting scientific research and development activities on demonstration scale.

Edotco Group based in Malaysia has installed the first carbon fibre telecommunications tower in the region.

The tower which has been installed in Taman Tasik Prima, Puchong is 70% lighter than a conventional steel tower whilst being 10 times stronger. In addition the company also said it was up to 50% faster to install and the anti-corrosive will contribute towards lower maintenance costs over the lifespan of the structure.

These features result in lower total cost of ownership of 20%. As the company gains more experience in the deployment of carbon fibre towers, customisation requirements will lessen, bringing the company closer to its target of 40% in TCO reduction.

The company’s next carbon fibre installation will be a rooftop structure in Bangladesh where it will provide a solution to building constraints. edotco is investing into high quality infrastructure and encouraging tower sharing where tenancy ratio has improved to 1.3 now.

Researchers at the University of Stuttgart’s Institute for Computational Design have created a new construction method using small robots.

University of Stuttgart graduate Maria Yablonina developed a carbon-fibre fabrication process that uses small robots. These robots climb the walls and ceilings working together to pull carbon fibre filaments across a space, creating a simple structure.

The project is a form of “swarm construction” a modern fabrication process that involves teams of small robots that work together reaching areas and creating structures that larger industrial sized robots can’t.

ICD director Achim Menges told Dezeen.

We are only at the very beginning of exploring the true architectural potential of this fabrication system. But we are convinced that its main advantage is that you can build entirely new structures that would be impossible to materialise otherwise.

The next step is to increase the number of robots, allowing them to attach the carbon fibres to other surfaces which would allow for more complex creations.

The Wilhelmina Canal is an important water way in the south of the Netherlands, and a vital part of the transportation infrastructure. In order to keep up with the increasing water traffic and increasing size of the ships, the canal is being widened and deepened near the city of Tilburg.

As part of the larger project, the existing locks II and III are replaced by a single new lock. Also, new sheet piling is installed along the canal sides and a more environmentally banks are being developed.

While smaller composite lock gates have been installed in the past, so far the number of installations have been limited. The use of the large composite lock gates (size of each part 6.2 x 12.9 m) in the Tilburg project, means a major breakthrough in the acceptance of composite technology for this demanding application. The individual gate doors need to have very high strength and stiffness, and are required to resist water in continued contact for over 80 years, whilst surviving any potential impact of ships in that time.

“Lock gates in composite materials are highly competitive in terms of cost compared to traditional material solutions based on steel and wood”

The composite parts were designed, engineered and manufactured by FiberCore Europe using resins from Aliancys. The large parts have a relatively low weight (24 MT) which is significantly lower than comparable solutions in steel and wood (respectively 50% and 25% less). This makes the installation much easier, requiring simpler equipment and upfront preparation. Because the fact that the specific gravity of the gate material is fairly close to the one of water (unlike steel), the wear and tear on the pivoting points is greatly reduced.

Once the project is complete, larger vessels should be able to sail through this section much faster, which would mean less congestion and heavy traffic on main roadways. The improvements to the canal will also create additional economic opportunities in the south of the Netherlands, as businesses are increasingly using the canal network for delivery of products.

Located in Nomi, the three storey building is a workspace, exhibition area and research facility for Japanese fabrics manufacture Komatsu Seiren. The carbon fibre strands created by the client company, are made up of a thermoplastic carbon fibre composite called CABKOMA Strand Rod. The product is considered the lightest seismic reinforcement in the world with a 160 metre long roll weighing in at just 12kgs.

The carbon fibre material creates a light and very strong rope like rod that is said to be ten times stronger than iron. Using computer technology the position of the carbon rods were calculated to respond to the seismic force and motion generated from north to south, and east to west.

The lightweight carbon fibre composite has also been used on the inside of the building which features white draped fabrics that replicate the exterior. The green roof is topped with another Komatsu Seiren product called Greenbiz, a porous spongy ceramic panel made using the waste material generated from carbon fibre production.

Apple has shared some updates on its ongoing construction of its new campus, scheduled for completion in January 2017.

Alongside new building renderings, the company shared pictures with Mashable on the progress being made on its “Theatre” complex, the new area where they plan on holding future product events. Due to space issues with their current campus, Apple typically rents out buildings for its press launches at venues such as the Moscone Centre in San Francisco.

Designed by U.K.-based architect firm Foster+Partner, the new underground theatre occupies around 120,000 square feet and can reportedly take around 1,000 people. The cylinder-shaped lobby at ground level matches the main campus building and is encased in glass which provides visitors with a 360 view of the surrounding area.

The 80 ton roof which Apple believes is the largest freestanding carbon fibre roof ever made, was created by Dubai-based Premier Composite Technologies. It was assembled and tested in a Dubai desert before being shipped in pieces to Cupertino, California. The circular roof is made up of 44 identical radial panels averaging 70 feet long and 11 feet wide, and each connects to a small central hub positioned in the middle.
