3D laser scanning: the perfect choice for fast-growing automotive industry

The automotive industry is firing on all cylinders – especially here in Tennessee. For the fourth year in a row, the state has been ranked No. 1 in auto industry strength.

 

Not only has Nissan been operating here for 30 years, but Tennessee is also now home to General Motors and Volkswagen’s operational plants, as well as Magneti Marelli and a number of original equipment manufacturers. In the last year, Tennessee hosted 44 automotive projects generating over $1 billion and thousands of jobs.

 

Earlier this month, GM announced plans to add 1,800 jobs at its Spring Hill assembly plant over the next three years so that it can begin building two new midsize vehicles.

 

In June, Nissan Motor Co. announced that it will add 900 jobs at its plant in Smyrna, just northeast of the GM plant. Also this month, Nissan announced plans to up production of its electric motors in its engine factory in Decherd, Tennessee. The plant is already staffing up to launch a third work shift to accommodate production.

 

As the automotive industry continues to grow, 3D laser scanning can play a major role in the redesign and construction of these plants.

 

This high definition scanning technology is the perfect tool to help automotive manufacturers retool their assembly lines, update their as-built drawings, and maximize efficiency of their production line layout.

 

How, exactly, can 3D laser scanning help?

 

#1: Reduced risk. Not only is laser scanning safer than traditional scanning methods because it allows crews to measure in places that would have previously been impossible, 3D laser scans also save money by eliminating the need for construction reworks and field retrofitting. Because of the quality of the scanned data, the number of change orders due to design flaws and unknowns is dramatically reduced.

 

#2: More precise. A laser scan takes multiple scans to collect millions of data points that are then registered together to generate a single three-dimensional “point cloud” that provides accurate distances and elevations between points on X, Y & Z coordinates. This accuracy provides the ability to perform better simulations and visualizations for training and monitoring purposes.

 

#3: Regulatory compliance. As governmental regulation and scrutiny increases, factory owners must ensure the as-built and as-maintained condition of production assets is in compliance. Laser scanning can be used to ensure plants are always safely within the regulatory guidelines.

 

#4: Huge cost savings. Laser scanning enables designers and engineers to revisit the original scan multiple times without having to physically return to the jobsite. Coordination between design and construction teams is greatly improved by providing visual documentation for discussion, and expensive construction reworks are greatly reduced.

 

Additionally, schedule compression of as much as 10% has been reported when 3D laser scanning has been deployed. This means big savings – especially on projects where outage time can cost as much as $1 million per day!

 

Conclusion

As the automotive industry continues to expand, 3D laser scanning technology can be an invaluable asset to the construction and redesign efforts of auto manufacturers to increase accuracy and efficiency while significantly saving both time and money.

3D Forensic Scans: Three civil applications

In my travels along the 3D laser scanning superhighway, I’ve spent a lot of time talking to criminal forensic experts. This group was one of the earliest adopters of laser scanning technology and I’ve had the pleasure of meeting agents with the FBI, the Secret Service, and even generals and admirals who are familiar with its capabilities.

In my experience, the most advanced groups in the specific application of the technology to prevent and investigate crimes have been the Secret Service and Scotland Yard. Both have programs written specifically to analyze the data and use it proactively to protect kings, queens and presidents.

High definition scanning allows you to check every site line – not just one or two.

Our firm has worked on several “criminal” projects over the years – some supporting the prosecutors and their evidence and others supporting the defense teams and their clients. But we also work with the litigation and documentation of forensic evidence for civil or construction projects.

Many jobs require our expertise to go out and document the existing conditions of a site. We have literally traveled from Montana to Texas to Georgia working with clients on various cases.

Perhaps the most famous civil forensics projects were the scans used for analysis of the World Trade Center attacks and the Minneapolis bridge collapse. On both of these projects, the scan data after the destruction of the structures was used to determine exactly what caused the failure.

Obviously, in the World Trade Center, the initial impact of the plane created the fire ball and damage, but it was the fuel in the plane that heated up the beams in the structures and ultimately caused them to fail, each floor collapsing on the one below as the entire structure came down. The melted beams were documented with laser data.

Structural Integrity

One of our first projects was scanning a three story parking deck. During the initial walk around, we could tell that the deck – even though made of concrete – was warped and some of the columns were out of plumb. Other areas were cracked and stressed.

We produced plans and models with the data and structural engineers were able to determine that the structure was unsafe. Because of the density of the data sets, engineers were able to look at all surfaces rather than a few strategic spot shots before making their final determination.

By being able to look at the line of the vertical columns through the building, engineers could tell that the cost to fix the failing structure would be much larger than building new.

Large Vessel Analysis

We also had another project where we were asked to scan a large containment vessel that held various types of liquid depending on the product being produced or stored.

In this type of investigation, we were able to document that a certain vessel was out of plumb, warped or bent. This information was then used to determine if the vessel was safe and, if not, how and when to replace it before a failure occurred.

Settlement Monitoring

Being able to monitor when and how much something is settling is very important to a property owner. We recently worked on a very large project in the western United States that involved a large platform used for loading and unloading products.

In this case, one long section had settled much more that the specifications allowed and had begun leaning at a dangerous angle. The engineer showed me previous surveys and I asked him why they needed us if they already had survey data on the structure.

He explained how the parties involved were having difficulty understanding the traditional survey data and its implications.

Once we scanned the platform in 3D and modeled it, it was quite obvious to everyone how badly the shape of the original structure had changed, as well as the principal cause of the failure. This helped move the group discussion from, “There isn’t a problem,” to “How do we get this fixed?”

We have completed many other civil forensic projects for engineers ranging from dam failures to vertical wall failures and even construction slabs that were not level or flat. The common element in all of these projects was that the use of laser scanning technology was the perfect tool to document the conditions and the data was easy to interpret and model into a visual form that everyone could understand.

Forensic scanning of crime scenes will continue to grow, as will the 3D laser scanning of complicated civil projects. 3D laser survey data is becoming mainstream in analyzing the cause of catastrophic civil construction failures. If you know how something fell to the ground, you can usually tell what failed first.

3D Laser Scanning: The New Industry Standard

When we first started laser scanning back in 2005, we replaced some of our total station surveying equipment with scanning technology. As much as anything, this was a great way for us to learn how to use the technology and understand its capabilities and limitations.

Early on, much of the work we did involved transportation projects and large complicated intersection surveys. There were many immediate benefits. For one, our surveyors were no longer put out into traffic and in harm’s way.

Another benefit was that we didn’t have to drive across town or across the state just to check on a few ambiguous points in a survey. Instead, we could just go back and look at the point cloud.

Today, in 2012, the entire world of architectural and engineering design and construction has changed. While before we had to convince clients of the benefits of using laser surveys, we now have a growing client base that simply will not consider starting a project without one.

In addition to providing accurate spatial information to civil engineers, plant designers, architects, contractors – and even insurance companies and crime scene investigators – laser scanning saves both time and money.

The truth is that in very complicated environments – like a mechanical heating and air conditioning plant room or a baggage room in an airport – the cost of scanning is nominal when compared to the total cost of the project.

Here are four primary reasons 3D laser surveys, or high-definition scanning, is quickly becoming the new industry standard when it comes to making precise measurements in complicated environments:

Reason #1: Scanner Speed

The speed of scanning has changed dramatically compared to what it was just seven years ago.

The first scanner we purchased (and still use today) took one hour for a 360-degree spherical orbit. Today, with our current scanners, it takes just six minutes.  This speed enables us to take many more scan set-ups than we used to take.

With our phase-based high speed scanner, we can now get 40 to 60 scans per day, which is very adequate to cover a large two-story mechanical room. To get the same amount of scans seven years ago would have taken a week.

In areas like these, it is the detail we look for, not the range. In extremely complicated areas, we make a set of scans on all sides. This data is invaluable to designers because it allows them to avoid interferences that often occur in these types of areas.

Reason #2: Software Improvements

Improved software programming has also contributed to the widespread acceptance of scanning technology.

I remember talking to clients back in 2005 and our message was something like this, “We will scan for you, then give you a 2D deliverable set of drawings that you can use to design your project.” When they would ask if they could use the point cloud in their design, our answer was always the same: “Yes, but you will have to buy $10,000 worth of software.”

As you can probably imagine, this was not an easy sell.

Fortunately, today Bentley, AutoCAD and Revit all have point cloud engines in them. The difference between an engine and a viewer is that we can now load a point cloud into an “engine” for a client and they can use the data in the design without having to purchase expensive “point cloud” software.

In fact, one of the takeaways from a scanning conference I recently attended was that all of the major software providers are moving to full 3D software design systems. They finally understand what we have known for years. Why would you survey in 3D, flatten the data to 2D, design in 2D then build in 3D? It just doesn’t make sense.

Reason #3: Clash Detection

This alone is worth the cost of a 3D laser survey.

Consider that if a project is modeled in the design phase, the completed final design – including the MEP systems, air handling systems, structural system and all of the architectural design – can be placed within the point cloud and clash detected. Anything that interferes with another system can be seen immediately and corrected before construction.

This is huge! What prudent engineer, designer or contractor would not want this advantage?  How important would this be to an owner?

Reason #4: TrueView or 360-Degree Spherical Photography

This technology has also improved quite a bit in the last seven years. When we first started scanning, we were fascinated with the fact that scanners could take photographs of the surrounding area, and then take that photographic data and overlay it with the scan data to make general measurements to the environment.

Unfortunately, back then the on-board camera was not as good as we had hoped and sometimes the pictures would come out octagonal and disjointed. As the process became more refined, we were able to mount a high resolution camera on the scanner and produce a crystal clear, color spherical photograph of the site.

This is a big step because it allows you to view a site from any scan set up. You can add text and information to the photographs and then e-mail a specific view to a client across the country or across the world. (In this case, some of our clients pay for our scanning fees with their savings in plane tickets!) This tool also enables clients to look out from the center of every scan and saves lots of time and discussion as to what is or is not located in the area of interest.

High definition scanning has quickly evolved from an emerging technology to an industry best practice when it comes to complicated projects. The construction process always includes many unknowns and the chance of design and construction errors is always high.

Why put yourself in the position of having to explain how a construction project was slowed down or over-budget because a laser scan was not the foundation of the project?

3D Laser Scanning and the Trayvon Martin-George Zimmerman Case

We have all heard and seen the news reports of the terrible tragedy that occurred in the altercation and subsequent killing of Trayvon Martin by George Zimmerman.

The case will be prosecuted on the facts of whether Zimmerman was acting in self-defense or whether he was stalking Martin and therefore the aggressor and his fate will likely be decided by a jury.

Watching the extensive coverage of this case, I noticed a laser scanner on the scene in some of the many news reports. I don’t know exactly how the data collected will be used, but I do know many ways that it could be used.

Police departments all across America are purchasing high definition laser scanners to use in their crime scenes investigations. Prior to laser scanning, a series of photographs would have been taken and lots of notes and measurements recorded as a way to document what happened.

Until recently, that was the best way to thoroughly document a crime scene.

But as soon as a scene is released, it is contaminated, making it unlikely that more useable evidence will be found. 3D laser scanning has changed all of that.

First used on crime scenes by the FBI, Secret Service and Scotland Yard, laser scanning is now becoming a “best practice” for the documentation of a homicide. There are many reasons for this, but here are just a few:

  1. The 3D element: Scanning a scene in 3D enables all of the evidence in the scene – from the buildings, sidewalks, parked cars, and surrounding areas – to be preserved in three dimensions. This means that you can look at the scene from every possible view, not just the view of the photographer and camera angle.
  1. Data capture: As cases progress, there will be evidence that comes up later that was not looked for originally. If you have done a thorough job of scanning, objects like drink cups, candy wrappers, or even potential weapons that were unknown at the time can be seen in the scan. This has proven to be an excellent tool for the prosecution in criminal trials. Many cases have been helped by data captured in a scan that was totally unknown at the time of the initial investigation.

So how can this technology be used in the Trayvon Martin/George Zimmerman case?

If you remember the scene where the killing occurred, it was on a sidewalk between two adjacent apartment buildings. There were many witnesses who testified that they heard and saw all or part of the incident from inside their apartment.

With a thorough laser scan, you could easily capture the view from each window in the adjoining apartment building. Armed with this data, if Witness A later says he saw the incident from his window and Witness B says she saw something from her window, you could easily use the 3D ‘point cloud” (dense scan data) to go behind the windows referenced by the witnesses and check the exact line of site.

This view would essentially allow investigators to stand in individual apartments and view the crime scene in 3D, enabling them to confirm or refute the testimony of a witness as to what they said they saw.

This extremely detailed data would also enable them to determine if something like a lamp or curtains was inside the apartment and obstructing the witness’ view.

This type of scan actually exonerated an accused person in a California case in which a man was accused of shooting his wife from his house, across the road from a hill where she was walking.

Several witnesses reported this. Turns out, the police scans showed that the line of site from the man’s window to the path the victim was walking on was blocked by low trees and high bushes. No one inside the house could have seen the victim from this viewpoint.

This knowledge ultimately led police to continue their investigation and eventually catch the guilty party.

High definition scanning can also be used to compute the exact location of a shooter. If a bullet enters a house from the outside and goes into the wall across the room – and that room is then scanned – the exact path of the bullet can be shown with a great degree of accuracy.

If multiple shots penetrated the house, the evidence is even more compelling. Because of the multiple trajectory lines that are formed by multiple bullets, the area of shots will be very precise. This data can help determine if the shots came from a house across the street or from a parked car in front of the house, for example.

The tunnel that Princess Diana’s car crashed in is still probably the most thoroughly scanned crime scene in the world. The scan data, combined with the physical data, was able to help determine the precise path of the car.

Similarly, there have been several scans conducted of the “Grassy Knoll,” where a second shooter of President Kennedy was allegedly positioned. In this case, however, there was no conclusive evidence.

I don’t know how the Trayvon Martin-Zimmerman case will ultimately be resolved. I’m not even sure if the authorities with the data understand completely how it can be used. But I do know that courts across America have allowed laser scan data to be introduced as evidence in all types of trials, both criminal and civil.

What used to be viewed as an unproven technology has now become much more common and mainstream.

Then there is also the other side – the defense team. If they know how to more effectively leverage the collected data, they may be the ones to show that what a witness said he saw was not possible from the data collected by the prosecution.

3D scan helps Feds catch vandals of ancient American Indian temple

The Nez Perce Indians of Idaho lived in the Pacific Northwest for many centuries before they bumped into Lewis and Clark in 1805. A peaceful tribe who lived mostly on the natural foods available in Idaho’s rivers, they probably never imagined they would one day use high definition scanning technology.

Fast-forward to February 2010.

In a small, little known rock shelter at a national park in Idaho, vandals used spray paint to deface ancient Nez Perce tribal pictographs, estimated to be some 2,500 years old. In addition to having both cultural and spiritual significance to the Nez Perce tribe, the rock shelter is located in a national park on federal land, which makes it a very serious crime.

LandAir Surveying worked with the Archaeological Damage Investigation and Assessment (ADIA), the U.S. Army Corp of Engineers, and the FBI to assist in a federal investigation to prosecute the vandals and document the destruction.

This wasn’t your everyday survey.

Our crews packed up their gear and boarded a plane to Idaho. Then they rented a car and drove to an access point on the Snake River in Hells River Canyon, where a jet boat was waiting to take them to the crime scene. The ride down river was exciting and rigorous, and the drop-off point was a small piece of land in the middle of the wilderness.

The colors and materials used to create the ancient drawings made it very difficult to capture all of the detail in the pictographs. After multiple scans – using a combination of laser scanners and GPS – over two trips, our crew was able to collect enough data to create detailed images of the rock face, as well as the defaced pictographs themselves.

Once processed, the data was presented to the Nez Perce elders, many of whom were very angry as they were seeing the vandalism for the first time. When we returned, we created color drawings, digital files and spherical photography that was used to evaluate and document the damage.

But ultimately, just two years later, justice was theirs.

Two Idaho men were eventually arrested and prosecuted for willful injury or depredation of U.S. property and were sentenced this February to federal prison and fines of more than $33,000 each for defacing the pictographs. A third man is set for sentencing in June.

What’s all the fuss about high definition scanning?

When it comes to making precise measurements in complicated environments, high definition scanning – or 3D laser surveying, as it is sometimes called – is quickly making its way to the front of the line in a wide range of industries from engineering to historic preservation.

Engineers use laser scans to work with real-world conditions in complex industrial as-built and plant environments. Construction companies use them to gather precise data on site terrain and renovations, and architects use them to check proposed design models against existing conditions to fine-tune their designs.

Even insurance companies and law enforcement have gotten on board, utilizing the technology to recreate large-scale accident scenes.

Why is it better? For one, laser scans are incredibly precise. Images are created from a “point cloud” of millions of points that can be measured precisely including the distances and elevations between points. They are also versatile. The scans, when used with digital color photos, can produce survey-quality files, videos or even 3D animated computer models and are so intuitive that even a novice can understand the information.

Laser scans are also fast. In 2006, when we bought our first scanner, it took almost an hour to produce a full dome 360 degree scan. Now we can scan in 6-8 minutes. This allows us to take many more scans and capture more detail than we did before.

Scanning almost always pays for itself. It is cheaper in the long run because you can revisit the original scan multiple times from your computer desktop without having to revisit the project site. Also, because the technology is so precise, the need for construction reworks and expensive retrofitting is minimized or removed alltogether.

For firms thinking about getting involved with this technology, there are currently three ways to capture 3D data on large scale projects: Airborne LiDAR (Light Detection And Ranging), Mobile LiDAR, and Terrestrial Scanners, which all produce LiDAR data.

Typical projects for terrestrial scanners are large pipes and tunnels, manufacturing facilities, plant process facilities, airport conveyor systems, bridges, buildings, towers and construction projects. (Our firm focuses on terrestrial jobs, as most cannot be readily scanned from airplanes or cars.)

The cost of entry into this kind of scanning is generally between $150,000 to $250,000 for the first units and software. (Although less expensive scanners are now available, software packages can still be expensive and the cost of training should also be considered.)

Aerial platforms and Mobile Platforms start at $500,000 and go up to $5,000,000. These units are constantly being upgraded with newer and better digital sensors and data management enhancements. We currently work with service contractors on these types of jobs, which are typically focused on documenting civil infrastructure on a much larger scale than terrestrial scans.

Projects could include scanning 100 miles of road to prepare a pavement analysis, mapping 1,000 miles of rail line, or mapping the City of Atlanta and producing 3D models of all the buildings.

If the cost of these units seems intimidating, keep in mind that firms that have already invested in these technologies are often open to partnering opportunities with smaller firms.

Small scanning focuses on objects the size of a Volkswagen all the way down to the mechanical components inside of a watch. The applications in this field – commonly referred to as “reverse engineering” – include quality control of manufactured parts or data capture for a manufactured process. A typical project could be scanning an ornate stair rail so that an exact replica can be created from wood, metal or composite.

This scanning method is so precise that you could dissemble a toaster, rifle or carburetor, scan the parts, manufacture duplicates, and they would all work when re-assembled.

What can be scanned?

If it can be built, it can be scanned. There is virtually nothing built that cannot be duplicated and modeled with current scanning techniques.

In addition to the engineering, construction and manufacturing industries, this technology is also being used by insurance companies and law enforcement to reconstruct accident scenes – like when a highway bridge falls during rush-hour traffic or a multi-car pile-up – and even on Hollywood sets. There are companies that make their living scanning elaborate movie sets before and after they are constructed.

To give you an idea of the wide-ranging capabilities of this technology, in the last month, we have scanned a 120-foot pipe in Chicago, a 737 aircraft in Delaware, a luggage system in LaGuardia, and the interior of a peppermill in Virginia. This technology is everywhere!

Surviving 2012: Six things every business can learn from the surveying industry

As a professional land surveyor for 40 years, I have a first-hand understanding of the housing downturn and subsequent economic recession we have been experiencing for the past six years.

At our firm, we began seeing the impact in early 2008, just one year after the peak in our business in 2007. Surveying is often viewed (at least by banks) as part of the construction industry and when construction loans dried-up, so did our business.

For surveyors, the hit was especially hard because our industry doesn’t just rely on the housing market, but also on commercial and retail expansion, which depends on the public sector to build infrastructure like new roads, sewer outfalls, parks, schools, airport expansions and industrial parks.

When things got bad, many surveyors began discounting their services in an attempt to hold onto their clients and market share. Over the past three years, for example, I have seen the fee and value of ALTA surveys – surveys required by banks before they will refinance a loan – sell for half of what they did before the fall.

The irony is that as the economy slowed, interest rates began to fall and investors, shopping centers and businesses began to refinance their properties. The need for ALTA surveys actually grew as a result! It was only a matter of months before attorneys representing banks began calling our firms asking for “ALTA updates,” implying something other than a new survey.

The firms of the future will be smaller with fewer permanent staff. Fees will change. It will no longer be just about how many crews you have, but how smart you are at collecting and selling 3D data. And those firms that can find ways to use existing sources of 3D data will be even better equipped to weather the storm.

For survey firms – as is true for all industries in this economy – the way to survive is to simply be a better businessperson. Here are six important things every business can learn from the surveying industry:

#1: Control your price. There are only two ways to control your prices: have a healthy backlog of profitable work and provide valuable services to your clients.

#2: Utilize subcontractors. Have a permanent staff large enough to process the workflow and provide quality control, but maintain relationships with good subcontractors and associate firms to expand your workforce when you have a wave a work that your permanent staff can’t handle.

#3: Make profit your goal – not billing. Just because you bill a crew out at $1,000 doesn’t mean you make $1,000. Your actual profits are typically closer to $150.

#4: Don’t buy – rent, swap and borrow. If you can rent a piece of equipment for $500 and make $150, you have greatly reduced your cash flow and improved your profit margin. Take a look at all of the expensive equipment you have purchased and must pay for every day. Unused equipment sitting on the shelf is not a good investment. Swap with other firms when you can, rent when you have to, and buy when the workload demands it.

#5: Always have a contract. Make the signing of a contract the starting point for every job. Even with an established client, having a signed contract can save a lot of scope creep and misunderstanding even on the simplest jobs.

#6: Don’t cut your price without changing the scope. Many lawyers have called to tell me that my price is too high. I remind them that it’s less than their price and they don’t even have to leave the office!

Lastly and most importantly, be realistic. If your workload goes down, you must cut your overhead immediately. For most of us, this means staff, which is always the hardest thing to do.

At one point, we had to reduce our employees from a high of 45 to just seven. We have since slowly built back up, but it was this reduction in staff, combined with tight cash management and a realistic outlook, that enabled us to survive.

The key to surviving this economy – for land surveying firms, as well as all business – is to be realistic, creative and adaptable. This is what it will take to survive and grow into better times.
