Electronic surveying improves accuracy on BIM-driven hospital project.
Electronic surveying improves accuracy on a @McCarthyBuild BIM driven hospital construction project and @SouthlandInd a mechanical contractor combines an electronic surveying tool with a BIM model to make significant productivity gains in a large-scale hospital construction project.
Using electronic surveying and BIM modeling, two-member crews were able to hit as many as 900 data points per deck per day
All is calm, form deck is ready for inspection and concrete.
For you contractors and engineers’ tech jargon: Stressing an unbonded post-tensioning tendon with a hydraulic jack (8-inch stroke). This tendon was roughly 130 feet long so it required two strokes. The elongation for a 100-foot-long tendon is roughly 8 inches.
3D Concrete Printing developed at Loughborough University is capable of producing large scale additive manufacturing, has the potential for producing full scale building components.
A demonstration of 3D construction using Contour Crafting where a robotic arm excretes clay or concrete and a metal guide is used to form walls that include a corrugated internal structure for strength. Because the walls are hollow, they have excellent insulating properties. Using Contour Crafting the shell of a 2,000 sq. ft. house, including floors, ceiling and roof, can be built in less than 20 hours custom designed on site.

In the video, Walt Disney Imagineering takes you onto the construction site to learn more about new innovative technology for instance using iPads,clash detection and B.I.M.
Using cutting-edge 3D scanning technology, crews from a nonprofit called CyArk have wedged themselves into seldom-seen spaces in four of the state’s 21 missions, bouncing 50,000 laser beams a second off centuries-old timbers. The idea is to map the fragile structures more precisely than they’ve ever been, creating virtual 3D models accurate down to millimeters.

SpaceX is exploring methods for engineers to accelerate their workflow by designing more directly in 3D. We are integrating breakthroughs in sensor and visualization technologies to view and modify designs more naturally and efficiently than we could using purely 2D tools.
