Point Cloud Performance Issues Solved for Revit

Many Revit users that do not have an issue with point clouds in Autodesk ReCap find those same files will cause performance issues in Revit, even with a high end computer.

Guest Author: Chris Alby, specialist with over 8 years of experience working in Revit. See the following – Revit articles and Revit families

Depending on the size and density of point clouds that you work with, typically if your computer can open the file in ReCap, it should be able to open it in Revit without crashing. However, just being able to load the file into Revit is not good enough, if you cannot comfortably work with it. Continue reading

FAA Part 107 Waiver for Flights Over People Granted

FAA Part 107 Waiver for Flights Over People

Hensel Phelps has been issued a Certificate of Waiver from FAA Part 107 for flights over people by using drones with parachutes.

From an article in Commercial UAV News.

Whilee Part 107 has enabled organizations to create and scale drone programs in powerful ways, the limitations around flights over people and beyond visual line of sight (BVLOS) operations have nonetheless limited how many of those same companies can apply the technology. In the construction industry, drones have given contractors unprecedented situational awareness of their job site and created immeasurable differences when it comes to safety, but the constraints of Part 107 have prevented many from unlocking the true power of the technology. One company has proven that they can sufficiently meet and exceed industry standards though, and that has allowed them to move beyond these regulatory limitations.

Recently, the FAA issued Hensel Phelps a Certificate of Waiver, allowing certified operators to safely fly parachute-equipped drones over people, including populated construction sites. These parachutes provided by ParaZero have allowed Hensel Phelps to deploy drone technology across their job sites while knowing they aren’t breaking any rules or regulations. Their approach will set a precedent for other organizations interested in pursuing similar operations, and the way in which they gained that approval is essential to understand.

Mobile Lidar Robots Will Map Car Assembly Plants

Mobile Lidar Robots

Ford is going to employ two of Boston Dynamics’ “Spot” robots, which are four-legged, dog-like walking robots that weigh roughly 70 lbs each, to help them update the original engineering plans for one of the transmission manufacturing plants. The plants, Ford explains, have undergone any number of changes since their original construction, and it’s difficult to know if the plans they have match up with the reality of the plants as they exist today. The Spot mobile lidar robots, with their laser scanning and imaging capabilities, will be able to produce highly detailed and accurate maps that Ford engineers can then use to modernize and retool the facility.

From an article in Tech Crunch by Darrell Etherington.

There are a few benefits that Ford hopes to realize by employing the Spot robots in place of humans to map the facility: First, they should save a considerable amount of time, as they replace a time-intensive process of setting up a tripod with a laser scanner at various points throughout the facility and spending a while at each location manually capturing the environment. The Spot dogs are roving and scanning continuously, providing a reduction of up to 50% in terms of actual time to complete the facility scan. Continue reading

3D Laser Scanning Least Disruptive to Schedule

3D Laser Scanning Least Disruptive to Project Schedule

The $4 billion launch of LaGuardia Airport’s new Terminal B Arrivals and Departures Hall, which opened June 10, is already garnering accolades. The use of a 3D laser scanning proved to be the least disruptive to the 4 year project schedule.

From an article in Construction Dive by Joe Bousquin.

From its soaring glass façade and 60-foot-high ceilings to artist Sarah Sze’s two-story hanging spherical artwork, the grand sweep of the 850,000-square-foot facility, known in aviation parlance as a headhouse, is enough to soften even the most jaded business traveler’s frayed nerves, especially those hardened by the old LaGuardia’s cramped, oppressive feel, which handled a record 31 million passengers in 2019.

Roadway Expansion Means Expanding Tools

point cloud Roadway Expansion Uses Many Tools

Roadway Expansion Uses Many Tools

When officials in Sarpy County, Nebraska began looking at ways to connect additional traffic from a new bridge built on Highway 34 over the Missouri River they realized it would require a lot of data for planning and design. Platteview Road would be a major connector of the most southern continuous east-west route expanding this two-lane roadway from the 1960s to a four-lane highway.

This is a guest post by Cyn Rene’ Whitfield at the Trekk Design Group.

This spring, TREKK used the combination of survey tools and the varying aspects of terrestrial mobile LiDAR, UAV LiDAR and UAV photogrammetry to establish the base mapping for this more than $100 million transportation project near Omaha. Within two days, we acquired 8.33 miles of two-lane highway, 2.71 miles of cross streets and 700 acres of farmland areas outside the current right-of-way. Continue reading

Comparison of Structure from Motion with UAV Lidar

In this paper a side-by-side comparison of structure from motion photogrammetry is performed with lidar using the same UAV platform. Thanks to Bill Gutelius at Qntfi for the lead.

The capabilities and utility of UAV LiDAR and surface from motion photogrammetry have been of wide discussion in the remote sensing community and assumptions made, often speculative, about the potential strengths and limitations of these systems.

3D BIM – What is the Real Adoption Rate?

The 3D laser scanning industry has certainly demonstrated that they have the technology to deliver an as-built 3D BIM. The question is – “Are the building owners willing to pay for it?

From a blog post in November 2018.

Slide for 3D BIM

3D BIM

I had a chance to speak with some knowledgeable people in the Boston commercial real estate market a few months ago. One was with a national real estate firm and the other with a large consulting engineering firm with over 1400 employees.

This was not at a 3D laser scanning event. These people had over 30 years of experience. They had no vested interest in 3D laser scanning, but were familiar with it.

UAVs Are Demonstrating Their Value in Construction

UAVs in Use on Offshore Platform

The construction industry in Europe is beginning to find that UAVs can improve productivity, reduce risk and improve profitability.

This is from an extensive article in Construction Europe by Mike Hayes.

While technology advances in the construction sector promise faster and more efficient working practices, productivity levels remain a thorn in the side for many European contractors.

Telematics, machine control, robotics and a myriad safety and uptime improvements can’t seem to defeat this stubbornly costly issue.

Cue the drones…or maybe not. It was not so long ago that unmanned aerial vehicles (UAVs), otherwise known as drones, were seen by industry insiders as gimmicks at best – toys at worst.
