LandAir Surveying at the Georgia Automotive Manufacturers Assoc. (GAMA)…

LandAir Surveying Company will be at the Georgia Automotive Manufacturers Association (GAMA) annual meeting today at the Volkswagen plant outside of Chattanooga, Tennessee. Volkswagen will be conducting facility tours for participants.

The plant, which started production in 2011, is a $1 billion facility and the first stage of Volkswagen’s goal of producing 592,000 per year in this area. This is one reason why Business Facilities magazine has named the state of Tennessee number one in automotive manufacturing strength for the fourth year in a row…

3D Laser scanning helps with job site safety

When most people think of laser scanning, they think of capturing and documenting existing conditions prior to a construction project.

 

While this is LandAir’s primary use of our laser technology, there are many additional benefits that our clients are beginning to take advantage of from the scans we provide. One of these benefits is safety, a priority for all of us in the construction industry.

 

Virtual job site

Laser scanning is a great way to incorporate new personnel into an environment. Enabling workers to view a job site prior to physically stepping onto the site is just one valuable resource provided by a scan. 

 

Whether it is identifying hazards on a site like open pits or high traffic areas, or just identifying where the lay-down areas for supplies will be, the ability to immerse workers into a site can protect them and cut down on miscommunications in the field. 

 

Visualization can also assist with language barriers that may be present on a site or tradespeople who don’t understand the entire safety plan of everyone onsite. It can also provide “virtual tours” to interested parties or at least help them identify caution areas before walking the site. 

 

Training

Laser scanning and modeling can also provide virtual training in a 3D space. The ability to identify parts on equipment and look at the space the equipment is in helps workers identify potential hazards and ensure that they have the necessary tools to make repairs or installations. 

 

There are partner companies today who are putting virtual “how to” training guides online that demonstrate anything from changing a tire to repairing valves in a virtual environment. This virtual 3D training not only allows for repairs and replacements to be done faster, which can save money on shut downs, but lessens the time workers are exposed to the elements. 

 

Many times, moving machine parts, extreme temperatures and dangerous spaces are involved with repairs or replacements and cutting down time in the field can help get workers out of harm’s way. 

 

Clash avoidance

Many times on job sites large equipment is present and cranes are erected. Staging these areas and making sure that the equipment has room to maneuver without colliding with anything else on a site is very important. 

 

Laser scanning can provide very precise measurements of equipment and the surrounding environment prior to being onsite. A crane’s radius can be measured, modeled and dropped into the virtual site to determine where potential clash areas may exist.

 

Risk management

In the event an accident does occur, having a laser scan of the site allows the team to go back in and examine the area where the accident took place. It may provide a better understanding of how the accident happened and who may have truly been at fault. 

 

Having a 3D laser scan of the existing conditions may help limit liability and demonstrate an added level of due-diligence. This information could also be used to create a guide for “what not to do” on future sites.

 

First responders and safety plans

Providing valuable information to first responders is another benefit created by a 3D laser scan.  Demonstrating the fastest and safest routes on a job site is something that can be easily demonstrated with a laser scan.

 

Floor plans can be developed or access to a web-based viewer like Leica’s TruView can allow 360-degree views of the environment. Evacuation routes can also be reviewed and demonstrated with a fly-through video for workers on the site.

 

Deliverables

The deliverables for 3D laser scanning that we provide are various and based on the needs of our clients. We provide drawings, models, fly-throughs and TruViews.

 

Autodesk’s AutoCAD and Revit are the two most popular formats in which we deliver drawings and 3D models. Our 3D point cloud fly-throughs are easily shown in Windows Media and Leica’s TruView allows clients to see our scan set-ups in full 360 views from each station. 

 

As the virtual world and building information modeling become more prevalent in the construction industry, new uses for 3D laser scanning that provide increased safety on job sites will hopefully increase as well.

3D Laser Scanning for Renovation of Healthcare Facilities

As a facility, hospitals and other healthcare buildings present a unique situation.

They have the aesthetic needs of a hotel or retail store, but the engineering requirements of an industrial or mechanical facility. These competing needs make space allocation difficult for design, construction, and operations and when renovations are due, accurate as-built information is absolutely critical.

3D laser scanning delivers perfect as-built information to meet the MEP and architectural needs of even the most complicated facilities.

Changes are always afoot in hospitals

Hospitals facilities are anything but static. Improvements in technology constantly call for new equipment and can shrink or modify the size of existing equipment. 

Equipment and mechanical rooms in hospitals are notoriously crowded. Walls, ceilings, kiosks, laboratories, and operating rooms are virtually full of pipes, wires, conduits, and other tools of the MEP (mechanical, electrical, and plumbing) world. 

This makes renovations difficult for both design and construction. 

There is a human factor, too. Office layouts change as employees are churned (or “moved” in facilities management terms). Departments often have to compete for space and square footage comes at a premium!

The health and safety of employees is also a consideration. Hospitals must comply with statutory requirements related to office layouts including the minimum amount of space per employee, security features, fire safety protocol, ventilation, temperature control, restrooms, dining facilities and more.

3D Laser Scanning: Perfect asbuilt information

3D laser scanning allows architects and engineers to design renovations from perfect as-built information. This directly addresses the need for accuracy within the tight tolerances of the hospital environment. Since human measurement error is eliminated, re-designs are greatly reduced and errors and omissions on the construction and architectural plans are also of no consequence.

3D laser scanning also gives contractors the upper hand. Since designs are based on actual existing conditions, the contractor can be more confident that it is constructible as designed.  Plus, precise material schedules developed from the model help avoid cost overruns.

The contractor can also use “clash detection” to determine exactly what must be moved or removed to complete the renovation. This technique compares the scanned as-built world to the construction plans and shows which areas are trying to occupy the same space. This significantly reduces change orders.

Owners and facilities managers also save money through efficient design and construction, as they can use the 3D picture of existing site conditions as a decision-making and communication tool during construction and a facilities management tool afterwards.

How it works

A 3D laser scanner uses harmless light rays to collect the 3D location of every object and surface it can “see” from where the instrument is set up. Scanners automatically rotate 360 degrees on a tripod, sending and receiving these light rays in all directions. In about five minutes, the scanner setup is complete and millions of data points have been collected. 

This data, which is known as a “point cloud,” is a perfect 3D asbuilt of existing conditions. The point cloud can be used by itself or modeled in a software program.

Advantages over traditional as-built techniques

3D laser scanning has many advantages over traditional measuring techniques including:

  • Accessibility: 3D laser scanners collect information from areas that can be seen but not easily accessed. For instance, scanners can collect information about MEP pipes and wires running along ceilings and other inaccessible areas.
  • Speed: Each scanner setup takes less than five minutes, so scanning crews can be in and out of an area quickly, without disturbing patients and without compromising the integrity of the data.
  • Safety: Since the scanners use harmless light rays to take measurements, neither patients nor field crews are affected. In fact, field crews do not have to be in a place to measure it.
  • Detail: No other data collection system records such precise information. Architects can see finishes, molding, and other aesthetic features and engineers can measure the locations of all objects seen by the scanner.

Conclusion

The strengths and efficiencies of 3D laser scanning are extraordinarily applicable to the unique environment of healthcare facilities. From design through construction and facilities management, all parties benefit from the precise as-built information given by this remarkable technology.

ICSC RECon Packed with Optimism

Las Vegas hosted the annual ICSC RECon Conference last week – the largest retail real estate convention in the world. This year had more than 35,000 attendees and a record number of individual companies. Most attendees were packed with meetings and the tradeshow floor was bustling with activity. 

 

The retail industry has definitely picked up momentum over the last few months and with the number of prospective sites and development renderings being displayed, it appears the next few years should be busy.  Many of the receptions and parties were back in full swing and the overall atmosphere was more upbeat. News on the home front was good as the Georgia contingent was represented by around 1,000 attendees. 

 

LandAir Surveying was busy discussing many new projects and exploring ways to assist in gathering as-built documentation. Two things I took away from the project discussions were:  

 

First, there is work out there and people are looking to make things happen! Deals are being done and getting valuable information into the hands of the parties doing the deals is in high demand. 

 

Secondly, because people need as-builts of existing space, this signifies that redevelopment is still very predominant. Many of the deals I saw represented in booths were infill projects, urban development and Transit Oriented Development (TOD).

 

While retail, and for that matter the economy as a whole, is not yet back to pre-recession days; there were many positive trends on display at the ICSC RECon Conference. Let’s hope this trend continues!

3D Laser Scanning Saves Busy Airports Big Bucks

We love airports here at LandAir Surveying – and airports love us, too! Airport managers need quality data quickly and with minimal intrusion, which are core strengths of 3D laser scanning.

Learn how we have been able to save big bucks for some of the country’s largest and busiest airports with 3D laser scanning…

Clash detection

3D laser scanning adds a lot of value to construction and remodeling projects inside airports, which are large, complicated facilities. Utilities, baggage handlers, human conveyors, escalators, and other features are closely packed together, making it impractical and expensive for architects and engineers to measure every feature individually (which would be subject to human error, anyway).

Conversely, 3D laser scanning does not miss important details and delivers an excellent asbuilt on a consistent basis.

Once scanned, we can perform a “clash detection” analysis by comparing the existing facilities to the new proposed design. In airport projects, often some existing features will have to be removed, whether temporarily or permanently, so we look for features from the asbuilt and new design that want to occupy the same space.

Using this technique, architects, engineers, and contractors can essentially “test” the new design against real conditions before construction begins. Contractors can easily see unexpected interferences and save money budgeted to fix these unknown “clashes.”

One of the biggest airport projects we have done recently was in Hartsfield-Jackson Atlanta International Airport. The client wanted to build a luggage conveyor through an existing portion of the airport. In this video of our scan, you can see that our software has painted all of the areas that clashed red, making them easily visible.

In our scan, we found that an unknown structural column was located in the center of the new proposed conveyor. The general contractor was able to save our fee and much more by identifying these interferences in the design phase rather than paying for them in the construction phase. Ultimately, our services more than paid for themselves.

Minimal intrusion

3D laser scanning also has the advantage of being minimally intrusive to patrons of the airport.  On top of being significantly faster than traditional surveying, the scanning process is much less obvious.

The scanner uses light reflected from any given surface without the need for another worker to hold a rod or mirror on the object being located.

For example, the airport in San Francisco needed an asbuilt of its luggage handling system, but this required data from the area where travelers actually picked up their luggage. With 3D laser scanning, we were able to collect the necessary data quickly and efficiently. Most of the patrons had no idea that they were even in an area being scanned.

Shorter runway shutdown times

3D laser scanning may lend itself even more to scanning an airport’s outside facilities.

When a runway has to be redesigned, it must often be resurveyed to account for settlement and movement. Survey crews must be able to locate the existing pavement, lights, striping, etc. Depending on the runway, this can take several weeks with traditional surveying methods and requires the runway to be closed.

With 3D laser scanning, data is collected in less than half the time. Plus, every square foot of the runway is captured as opposed to the traditional 25-foot grid. Airports face reduced runway shutdown time and our field crews are safer. It’s a true win-win scenario.

For example, one regional airport in Southeast Georgia needed to resurface its runway. They needed topographic data accurate to within ¼-inch and they needed it fast. We provided a scanning crew to quickly collect the data and delivered the project with the required accuracy within their required timeframe.

3D laser scanning’s ability to capture the entire runway can lead to the creation of more accurate glide slopes, which are the paths used by airplanes approaching the landing strip. We provided this service to Lockheed at the Dobbins Air Force Base in Marietta, Georgia.

Unlimited applications

There are many other applications for 3D laser scanning in and around airports. Recently, we had the opportunity to do a somewhat unusual scan for an airport in Arkansas.

Developers were planning to build hotels and other commercial properties around and adjacent to the airport property. However, several decades ago, large underground storm drains were installed through the proposed property with limited record of where these pipes existed.

We were able to use 3D laser scanning to determine the location, size, and dimensions of these storm pipes.

It was a tight squeeze, but our crew traversed through all the storm pipes from the river outlet through to the runway. The contractors learned where the pipes were, engineers learned their locations and storm water capacities, and the owner gained valuable information about its assets. 3D laser scanning benefitted everyone involved.

Hotel and Casino Markets Bring Big Opportunities for 3D Laser Surveys

It looks like 2013 will be a banner year for the hospitality industry.

In 2012, U.S. hoteliers collectively sold more than 1.1 billion rooms. Las Vegas welcomed a record 40 million visitors last year and nationwide commercial gambling revenues surpassed the $35.6 billion mark in 2011, up from $34.6 billion in 2010.

A recent study released by the American Gaming Association (AGA) reports that the commercial casino industry supported approximately $125 billion in spending and nearly 820,000 jobs in the U.S. economy in 2010, based on direct, indirect and induced impacts.

Though development, funding, business travel, convention participation and disposable income were almost non-existent over the last five years, the hospitality industry is making a comeback.

So, what does all of this mean to the construction industry? How can the AEC community, which has struggled for years, take advantage of this opportunity?

It already is. The number of projects in the pipeline has already greatly increased during the first two months of 2013 over the first two months of 2012. The AIA reports that the Architecture Billings Index (ABI) is reflecting its strongest growth since November 2007.

Not only is the number of new ground-up projects increasing, but renovations and expansions are also happening at a record pace.

Hotels and resorts are expanding, updating rooms, adding new restaurants, providing more services and implementing property improvement plans (PIP) that have been on hold.

As a result of all of this construction, we have seen a tremendous surge in the need for accurate as-built documentation from owners, designers, engineers and contractors.

They need to know what they have and they need to know fast – and 3D laser scanning and measuring services are in high demand.

In just the past few months, our firm has completed a wide variety of projects and requests including field measuring and verification of rooms, hallways and common areas; documentation of exterior elevations and connect points for building expansions, theatres, meeting spaces and parking decks; and complete renovations of old hotels or buildings being transformed into new facilities.

Here are just a few examples of some of our recent projects:

Hotel Renovation

We provided as-built documentation for common areas, hallways and over 100 interior rooms in a major hotel renovation project using laser scanning and laser measuring to produce AutoCAD documents and 3D models.

Rather than measuring each space then returning to the office to create documents, we utilized our laser data capture techniques to wirelessly import to a BIM workstation. This allowed us to measure and create 3D models and AutoCAD files on site and in real time.

We were able to generate floor plans, reflected ceiling plans and interior elevations in the field, which led to increased accuracy, reduced collection and drafting time, and eliminated the need for return visits.

The architect was able to begin work on floor plans immediately while we continued to measure additional floors.

Mechanical Room Boiler/Chiller Replacement

We generated a 3D laser scan of a 20,000 square foot mechanical room, providing a level of accuracy and detail that would have been unattainable with traditional measuring techniques due to the amount of heavy piping and ductwork required.

This enabled designers to drop their prospective model into the point cloud and determine clash issues and tie-in points. The laser scan saved field rework time, material costs and allowed enhanced coordination amongst the project team.

Casino Theater Addition

Because there was insufficient data on the existing condition of the space targeted for the design of a theater, we provided a point cloud and TruView to the contractor and design team via a 3D laser scan. The point cloud allowed for existing mechanical systems and structural elements to be measured and inventoried.

The results increased the speed of design, reduced cost of materials and field rework, assisted with developing a safety plan, and increased collaboration efforts between team members.

As the hospitality industry continues to expand, the demand for 3D laser surveying will increase as clients search for ways to save time and money on their construction and renovation projects. You can bet on it!

Five reasons to consider laser scanning in 2013…

Blog 5 photo c10 scannerI hope you are off to a wonderful New Year! In the theme of the New Year, I continue to be amazed at all of the new applications for laser scanning that our clients are coming up with or projects they inquire about measuring.

Hopefully this blog will inspire you to think of opportunities to utilize our services in 2013 to make your next project even better.

As-built data capture has always been a challenge for the AEC community and owners of assets. The outdated methods of gathering data are time consuming and lack accuracy and utilizing these record drawings can be inexact.

LandAir Surveying uses the latest technologies to help our clients. Whether you are looking for accurate as-built floor plans, historic preservation of a structure or MEP surveys in the plenum of a ceiling, we have an accurate and cost-effective solution for you.

Over eight years ago, we began utilizing the revolutionary technology of laser scanning. Our first laser scans were for the transportation industry, performing bridge surveys. Through these and other projects, we found laser scanning to be superior to traditional methods of data capture for a number of reasons:

#1: They are more precise.

A laser scan takes multiple scans to collect millions of data points. These scans are then registered together to generate a single three-dimensional “point cloud” that can be measured accurately and provides distances and elevations between points on X, Y & Z coordinates.

#2: They are versatile.

Laser scans can produce (when used with digital color photos) survey quality files, fly-through videos, BIM Models and CAD drawings.

#3: They are fast.

A single laser scan can be collected in around six to eight minutes. This enables crews to take many more scans and capture more detailed data than ever before. It also allows for accurate surveys to be done with minimal interruption to building occupants.

#4: They are safe.

Laser scanning provides a safer environment and allows crews to measure in places that would have previously been impossible.

#5: They save you money!

Finally, laser scanning almost always pays for itself. Here are a few examples of ways laser scans can save you money on your next project. Here are a few examples of ways laser scans can save you money on your next project:

  • You can always revisit the original scan multiple times from your computer desktop without the time and expense of traveling to the site again and again. With a laser scan, you can even revisit the site from your desktop years after the initial scan.
  • The quality of data collected can minimize or eliminate the need for construction reworks and field retrofitting.
  • The number of change orders due to erroneous design and unknowns in the field are dramatically reduced.
  • Material waste is reduced and the amount of production in the shop is increased.
  • Coordination between design and construction teams is greatly improved by providing visual documentation for discussion.
  • The speed of design is increased by providing accurate as-built conditions and clash detection.
  • Bid documents can be created from as-built data, resulting in lower-priced bids and a quicker schedule.

As you can see, the reasons for laser scanning are compelling. But what types of projects are best suited for this technology? In our experience, we have seen the greatest return on investment for laser scanning on projects that are complex and difficult to measure. Those projects with precise measurement requirements and a required speed of data gathering typically yield the greatest return on investment.

We have scanned miles of tunnels, airport conveyor systems, MEP structures that look like pipe “spaghetti,” hotel and casino atriums, and theaters and stadium grandstands with thousands of different sized structural beams. Laser scanning was by far the best solution for these projects.

While complex projects are great opportunities to utilize laser scanning technology, other advances in virtual design and construction solutions have allowed us to provide results for less complex environments.

New software and measuring solutions allow us to provide detailed as-built drawings and 3D models for hotel rooms, retail spaces, classrooms and offices with amazing speed and at a greatly reduced cost-per-square-foot over traditional architectural surveys. Field measurements to productions of floor plans and even Revit models can now be delivered in days.

From the industrial, manufacturing and energy sectors to hotels, hospitals and retail spaces – LandAir can provide solutions to make your next project more efficient and affordable.
