Is Augmented Reality The Next Evolution of BIM?

May 8, 2012 in Technology | No comments

Last fall, I wrote about getting past the hype of BIM and making it a reality on construction sites. Here is a way we are continuing to use and see BIM beyond the construction drawings. Augmented reality might be useful to you as well…

Augmented reality (AR) is defined as:

“a live, direct or indirect, view of a physical, real-world environment whose elements are augmented by computer-generated sensory input such as sound, video, graphics or GPS data.”

In sports, a good example is that yellow first down line seen on tv football games. The view you’re seeing on the field is reality. The line is how that reality was augmented. This same technology can be applied to real estate and construction, not just ESPN.

AR can integrate with BIM on both smart phones and tablets. In the future, AR might come in glasses like the Google X Concept seen here. The idea is to use the GPS in a device to sync current location to a 3D Virtual BIM model. This will give each user the ability to go to a job site and see the future of the construction within the model, from their own perspective. It takes “virtual tour” to the next level.

Taking the wealth of data that BIM provides, the user will have to have the ability to view a proposed 3D model in the actual environment, whether that is in a space to be remodeled, a Brownfield or Greenfield. This will be a huge step forward in bringing BIM to the jobsite and out of the office.

This video might give you a good test drive of what a BIM and AR teaming could look like. Here are a few ways we see this technology being used now and in the future as it evolves:

  • During the entitlement process to share how the “new project” will appear
  • An owner could see how the property itself would look from any vantage point inside or outside the building.
  • The architect or designer will be able walk around the model of the project to view up in the reality of the surroundings.
  • Excavator Operators could view the area of excavation, and the locations of underground utilities.
  • A building superintendent would be able to look behind walls, floors or ceilings in order to avoid damaging waterlines or studs.

We think that this is another step in how BIM integrated will continue to help us across the spectrum of design, entitlements, construction and facilities management.

How can you see augmented reality changing projects and property development?

BIM: Getting Past the Hype

November 23, 2011 in Construction Trends, Technology | 2 comments

Earlier this week, I met with a national architectural firm with whom we are partnering on a 2012 mixed-use project. I asked the principals what they thought of BIM and their response was, “it will become the norm for architectural and engineering work sooner than later–in less than five years.”

We also believe BIM will become the standard, but not without growing pains and good effort to learn.

We know firsthand. On our first BIM project, our building superintendent was excited about getting into they system. He liked having the flat screen in the trailer and the ability to manipulate the plans. Cool. I recently spoke with him and he hasn’t done a whole lot more with it since then. The hype took over, but substance has not.

I also recently visited a site where everybody was carrying around iPads loaded with BIM software and the talk was about it being the greatest thing since sliced bread. As I read the tea leaves, I fear there is a bit of hype here as well.

So, how do you get past the hype?

For us, it all lies in educating our team.

Realize the initial benefits.

  • Using BIM in presentations can help you win jobs. This works as a commercial developer, a building contractor or as someone trying to sell the construction of a new project within your company.
  • Using BIM is helpful for non-construction types. Most have difficulty visualizing two-dimensional flat plans, but BIM helps them understand what they are seeing.
  • Putting BIM into practice will reduce change orders. The “tool” reduces clashes and delivers the images of the product with more clarity.
  • BIM will eliminate collisions and overlap between trades, saving time and money.

Realized future benefits.

  • BIM will be a great tool for operations and facilities management after construction is complete.
  • BIM will probably lead to better customer long term relationships. Models will help us “own” the project or development.

Realize the obstacles.

  • Right now there are only a small group of BIM-capable personnel in the workforce. With the hype, one would think everyone is using is using BIM, but that’s far from the truth.
  • The software is at times difficult to navigate, even after training. We’re hoping for more use-friendly programs that can be easily used in the field.
  • There are folks in the field who have been reading 2D drawings their entire lives. Widespread acceptance of  the technology will require it to be as easily accessed as a set of paper plans.

Even with these obstacles, to me, BIM is worth the time and cost on the front end. The gains in efficiency and understanding of the project will be of great value to our customer relationships.

Have you been successful putting BIM into practice? What challenges have you overcome?

BIM and the Evolution of Drafting

November 11, 2011 in Customer Relationships, Technology | No comments

Recently, I talked with a major architectural firm about their use of building information modeling. To them, BIM is just another advance of communications and drawings. I can relate.

When I was in college, everybody used pencils. The quality of your lines on the drawings was most important. Then we moved to ink to give them more clarity. Then Auto Cad. We are now on AutoCAD 2012 v. 18.2 which means there have been 26 releases of the software.

As a company, we’ve advanced to the next level of customer-service centered modeling: BIM.

BIM is not a specific piece of software but a group of programs used together to build a data rich model. Stewart Perry uses software from AutoDesk who also own AutoCAD, so BIM is really just an extension of what we have been doing continuing to advance efficient ways of communicating. We use the following:

  • Autodesk Revit Architecture for structure and MEP for modeling
  • Autodesk Navisworks Manage for clash detection and presentation
  • Autodesk Navisworks Freedom for jobsite uses of BIM
  • Autodesk Quantity Takeoff for estimate and budgeting
  • Autodesk Buzzsaw for file management and transfers
  • Microsoft Project for scheduling

BIM takes the lines once drawn by hand on paper with rulers and pencils that evolved into lines on a computer screen created in drafting software. Architects, contractors and owners now have the ability to give meaning to the lines on the screen.

We can assign properties to items in a model that are quantifiable.

A line that used to represent a wall now can show a visual 3D representation of the wall, include information on stud spacing, fire rating and material choices, that can be accessed by those involved in the project.

Communication between the concept in the architect’s head and the reality of the end product has been a source of confusion, delay, and lawsuits. Now the architect can provide more information about the design than ever before. We couldn’t be more pleased.

As a company, we are out of the infancy stages of BIM. We have hired a BIM manager, and are using the technology on three of our projects:

  • Shoppes of Madison – Madison, AL
  • Brookwood Village renovations – Birmingham, AL
  • Redstone Gateway at Redstone Arsenal- Huntsville, AL
  • US Steel’s new headquarter – Birmingham, AL

Has your company started working with BIM? Have you been successful in implementation?

My Use of Social Media

January 27, 2011 in Customer Relationships, Leadership, Management, Team Building, Technology | 1 comment


Thanks to several social media tools, I have been able to stay connected with increased frequency than before web 2.0.  A couple of years ago we started using several  of these  and the effectiveness of helping with relationships has been very encouraging.  I can count on a brief exchange with someone due to my blog posts, as you see here, on Facebook or on Twitter.  On the other hand, I will say that social media can be a detriment to your time management efforts.

The internet is a large and highly populated space and it is easy to get lost or chasing rabbit trails. I compare it to someone looking into a refrigerator when one is hungry, but not really sure what they want, yet they open the door to see if anything has changed. Some would compare it to insanity; doing the same thing over and over and expecting a different result each time.

But through the use of Social Media, companies can now focus their attention on specific audiences much easier and start topics of conversation with just a sentence.  In addition, you can make people feel more important by personalizing the messages sent.  I enjoy reaching out to old friends to check on their well-being as well as business acquaintances, as I believe that this is a lost aspect of business today.

I believe that the economy is getting better and to me, it more important than ever before to be sure that you’re strengthening and maintaining relationships with your clients and associates in the most efficient ways across multiple platforms.

Listed below are some other blog posts to help you on your way:

Geotechnical Testing now, Saves Money later

December 9, 2010 in Construction Trends, Green Building, Technology | No comments

You can’t take anything for granted; even the ground under your feet. That’s why it is important to have Geotechnical testing done before construction begins on a project. But nothing is perfect, and even the best Geotech firms can’t always determine exactly what it is going on beneath the surface.

A Sinking Feeling

On one of our job sites, the crew arrived one morning to discover that the building slab had sunk about 5 feet, taking a nearby forklift down with it. It turns out there was a sinkhole below this area in the slab on grade. Plenty of pre-construction Geotechnical testing done, but none of the reports indicated the presence of this deep sinkhole.

On another project the geotech report indicated the water table had risen 20 feet in a six-month span. The engineer said this was because the region was coming out of a severe drought and that had significantly dropped the water table prior to the recent rains, but I was skeptical. After grading we discovered that there was surface material on the slope that had been acting as a dam. Once the material was removed, the water table dropped, no problems after all.

Infill Building Sites

We are increasingly working on infill sites inside metropolitan areas, which have been passed over for one reason or the other, often because of the challenge of that particular site. With these challenges, it’s easy for geotech testing to often overlook a potential problem until work actually begins. Geotech is important in those situations, but it’s not a perfect science.

Geotechnical testing is important, but it’s not a perfect science. If the reports are too good to be true, then it probably is. Practicality and common sense still have to factor into the equation, we have found.

Green Building Focus Recap: Chris Brogan on The Efficiency of Social Media

September 2, 2010 in Customer Relationships, Green Building, Technology | 2 comments

Last week, Chris Brogan and I spent 2 days together here in Birmingham. We were pleased to have him as our guest for the Green Building Focus Conference.

For those unaware, Chris is the well-respected co-author of Trust Agents and Social Media 101. He’s carved out a niche for himself in social tools online and the means, methods and leverage of Web 2.0. He’s teaching business leaders how to stay connected and in the game.

In his talk, Chris compared Web 2.0 and its tools to the telephone when it was invented. At the time, many maintained they would rather write letters and talk in person than use a new device. Even though it enabled them to communicate across hundreds of miles, people were reluctant to move past the familiar. This compares to where we are now in business communication, particularly in relation to social media. The phone and email are now tried and tested ways of staying connected, building relationships and increasing profits, but are they the future?

I found Chris to be genuine, transparent, honest and helpful, both individually and on stage. He is the kind of person who makes you feel like he’s interested in what you have to say and gives you his undivided attention, one-on-one. There were so many takeaways from my time with Chris, but in interest of brevity, I’ll share just a few that relate to social media.

Be in it for others. The ratio you spend helping others should be 12:1 when compared to what you do to promote yourself. Strive to build long-term relationships and trust.

If you do it, do it right. After Chris explained the various social networking tools that work well for him, he made the point that it was best to choose what you can do well and maintain properly.  If you spread yourself too thin, you will represent yourself poorly.

Keep mobile top of mind. As more people are becoming reliant on their smart phones for web use, make mobile a priority when designing a site. A budget spent on expensive flash and non-compatible design is often money wasted.

Reply. Chris suggested that his popularity is attributed to the fact he actually takes the time to respond where many experts do not.

To sum it up, the more I learn about these new tools and their leverage, the more intrigued I become with delving deeper. After all, social media uses less carbon and less effort, often gaining more results. How’s that for energy efficient?

Game Changers, Green and Leverage for Good

August 18, 2010 in Green Building, Technology | No comments

Next week Birmingham will host the Green Building Focus Conference and Expo.

Experts in the field will be here—Karan Grover from India, Llewellyn Van Wyk from South Africa and Dr. Charles Kibert to name a few. It’s a gathering of like-minded individuals who are interested in sustainable designs and construction, conservation, recycling and reuse. Each will share knowledge with others, all while learning. We are bringing Chris Brogan to Birmingham as a speaker and participant at the event.

Chris is a social media guru. Why is he a fit for this event? I have been getting that question for months. Very simply, Chris and others in this field have mastered the use of Web 2.0 to be trust agents, not marketers but digitally savvy “regular people” who use the Web to humanize and be transparent, honest and genuine. They leverage action tasks for good. To me, it’s a natural fit. Chris has wisdom to share about how to use the Web to influence and build relationships that promote the initiatives of the GBF.

I got a chance to visit with Chris on Monday at his office in New England, beyond the normal “getting to know you” chat. We talked about things that are important in each other’s lives and the trails we have taken over the years. (He is younger on the trail than me.) We talked about the Web. We talked about helping others and not expecting anything in return. We talked about the times in our lives when we have truly struggled. Genuine. Honest. Transparent. And yes, we are trying to make a difference for others as we move along.

I hope you’ll be able to make the conference next week. I can assure you that Chris has a lot to share.

Notes From a Pervious Concrete Seminar: How “Sustainable” Becomes “Practical”

July 2, 2010 in Construction Trends, Green Building, Projects, Technology, Tips from the Field | No comments

This week, several of our team attended a workshop led by Matthew Offenberg, a recognized expert in the field of pervious concrete. The discussion centered on the design and function of pervious concrete pavements, new developments in the technology and some of the challenges in implementing it. I found it interesting that the workshop was held here in Birmingham, an area known for its impermeable clay soils.

Our company has experience with pervious pavements in coastal areas with sandy, drainable soils. We will install our first pervious concrete parking lot in this area this month. Apparently, we aren’t the only ones expanding our use of this sustainable method. Factors that have contributed to the spread of the pervious industry to areas not originally thought to be candidates include:

Increased land values. The growing scarcity of suitable building sites have pushed developers and planners to squeeze more out of the site, and getting rid of the detention ponds creates more space.

Availability of materials. Readily accessible and relatively inexpensive crushed stone makes the addition of a “drainable layer” under paving easier in areas similar to Birmingham.

Industry growth. We now have more qualified suppliers and contractors, training programs and continuing education programs. This provides more resources and experience to draw.

As these and other sustainable technologies become tested by time and experience, their popularity will grow. In this instance, sustainable has become practical, and we consider that a success. Here are some pros and cons regarding the implementation and use of pervious concrete:

POSITIVE

  • Allows drainage of storm water directly into sub-soils
  • Omits the need for expensive retention/detention ponds, saving valuable land space for other uses
  • Structurally self-supporting water storage units can be placed under pervious concrete for irrigation use
  • Can be placed over tree root systems allowing for limited space traffic use
  • Can be placed in run-off buffer zones expanding traffic use space
  • Omits need for extensive storm drainage pipe systems as well as curb and gutter
  • No reinforcement required

NEGATIVE

  • Periodic cleaning required to maintain porosity, but minimal maintenance otherwise
  • Relative weakness does not allow for heavy truck traffic
  • Some raveling may occur over time, especially along edges—may require regular concrete ribbon along edges
  • 6” minimum thickness for light duty traffic
  • Requires substantial porous substrate for positive drainage
  • Must be kept covered and barricaded for a minimum of seven days after initial installation
  • Freeze/thaw spalling can develop in northern climates where there are extreme cold temperatures.

For us, the pros outweigh the cons when it comes to pervious concrete in the right applications—it maybe something to consider when you’re planning your next project. It’s a good option for the environment and an overall value-add.

On the Horizon: A Concrete that Eliminates Storm Water Management Systems

May 28, 2010 in Conservation, Management, Preservation, Projects, Technology | No comments

We try to keep our finger on the pulse of best management practices for today’s construction. To us, that happens when quality means/methods balance with an eye toward the environment. Pervious concrete can do both.

Pervious concrete is a wonderful concoction that holds up structurally and is porous enough that water can seep through it and flow back into the aquifer. It has polymers that glue the aggregate together, simultaneously allowing open cells to be formed in the concrete. The top inch filters out particulars such as oil and grease and the storm water flows through.

We had our first encounter with pervious concrete 5 years ago on one of our Florida projects. Since then, we have used it on several more sites. Here’s what we have learned from our experience:

● The product works better on sandy soil, which affords good drainage.

● Some pervious pavements fail because of insufficient drainage, especially in climates that experience heavy winter freezes that harden the ground.

● Shale aggregates in the concrete can break under freeze/thaw conditions, clogging the water flow.

● The selection of aggregate in the sub-base is important, and the curing process is crucial. A seven-day, wet-curing period is what we have learned works best.

Pervious concrete is a Best Management Practice recommended by the Environmental Protection Agency. While it is a little more expensive than traditional concrete, additional cost will be balanced by the reduction or elimination of traditional storm water management systems like retention ponds and sewer tie-ins.
