3D Printed Steel Bridge

3D printing technology has quickly advanced from science-fiction to concept to novelty to legitimate construction technique in an amazingly short timespan.

3D printing works like standard printing but adds the vertical dimension to the normal up-down, left-right dimensions inn order to ‘build-up’ a shape.

EPS Foam Concrete Forms

Expanded polystyrene (EPS) is a light-weight, inexpensive, rigid material that is commonly used in packaging and as an insulator. It can be formed in any shape and is stiff enough to support normal-weight concrete.

Freeze/Thaw Protection

Exposure to cold weather is believed to damage and destroy millions of cubic feet of concrete annually; from buildings to roadways, dams to bridges. Any time concrete is saturated with water and frozen to 25°F or less.

Flat-Pack PC Concrete Arch Bridge

Segmented-arches are an ancient form of construction. But after centuries of limited use, they are making a come-back. The example shown above is installed in sections to achieve the desired width of the bridge. After the foundation, abutment, and wing walls are built; the bridge portion itself can be placed in a day or so without the need for shoring, bracing, or formwork.

Tunnel Form Construction


Tunnel form https://www.viagrasansordonnancefr.com/viagra-prix/ CIP is a modern method of construction (MCC) of building cellular structures using reinforced concrete. The method combines the quality, speed, and accuracy of factory production with the flexibility of on-site building.

Drones Provide Hi-Res 3D Mapping


Just in time for Easter, Pix4D and Aeroyn Labs has given us the only 3D digital record of the iconic Christ The Redeemer statue in Rio, Brazil. What makes it interesting is that it was completely mapped using aerial drones.

Combining very accurate GPS locating and hi-res cameras with drones makes for a cost-effecting and safe way to quickly map structures of any size and shape.

The Science of Salt

Deicing chemicals are the most common form of ice control and are necessary to prevent accidents and improve traction. Most of the time these chemicals are used without any thought toward the effect they have on the structure, surface, or roadway. Concrete in particular, can be significantly damaged by these chemicals.

Metallic Wonders

Though advanced ceramics, carbon fibers, and other new materials become more prevalent in construction, metals are not about to give up their dominance yet. Here are some fascinating metal materials you may not know about:

Amorphous Metal is basically metal lava or metallic glass. Composed completely of metallic atoms, it is cooled quickly before the atoms can align into a crystal structure. The disordered structure makes the metal amazingly hard, twice as hard as steel alloys of similar mass and volume. The downside is that its hardness also makes it brittle—just like glass.

Hot Weather Concreting

As the weather heats up it’s time to introduce hot-weather practices during concrete placement. Such practices typically involve using cooling mists, moist curing, retarding admixtures, low temperature mix water and even ice.
