What’s Your Jobsite Photo Strategy?

August 4, 2010

When speaking with managers and executives from general contractor firms I make it a point to ask about their corporate strategy for jobsite photos. Ninety nine percent of the time, the response is “well, we don’t have one.”  Wow.

I’m sure if I asked the same question about estimating, scheduling, project management or accounting, one hundred percent would be able to convey their strategy to me. Yet, the one resource they have with the potential to irrefutably convey the value of their work isn’t worthy of a corporate strategy. Talk about an under-appreciated resource.

4D 5D Can’t Complete the Picture

July 29, 2010

For all the promise of 4D and 5D BIM technology, users can never capture the reality of jobsite conditions and their impact on a building.  Yes, including the dimensions of time and cost adds a stronger connection between design and construction. But there are many components of “as-built” construction that BIM can never capture. There are certain conditions that can only be accurately and comprehensively recorded in photos and video.

Here’s a partial list of conditions and I welcome you to add others:

  • installation processes
  • access issues
  • sequencing issues
  • use of specified materials
  • fabrication processes
  • water intrusion remediation
  • LEED point qualification

Finally, before you convince yourself that as-built conditions can be completely represented in a BIM model, remember that human beings are the connection between the two.

The Photo-Data Transformation

July 22, 2010

In my previous post I identified the cost associated with extracting information from the photos and video used to capture ground level information from construction project sites. Information extraction costs are a function of time once the project ends and eventually reach impractical levels as the project team disbands and their tribal knowledge of the project evaporates forever.

But it doesn’t have to be that way. What if the project team could encapsulate their tribal knowledge into an archive that remained accessible to the project team and the owner of the finished building for the duration of the building’s life? – Time out. You may be thinking, um, OK Geedra blog dude. Are we talking about some kind of Vulcan Mind Meld?

By packaging the visual media (photos and/or video) with the project team’s intimate knowledge of the images in the media into photo-data, we can make that information accessible without incurring the extraction costs associated with current forensic research efforts using construction photos and video. The components of photo-data include data tags (for indexing and research), annotations (tells the story of the image), contextual references (other photos, floor plans, reports) and any other supporting information.

Once converted, photo-data information will be resistant to degradation over time, making it as accessible 10 years after completion as it was 10 minutes after the photos were taken. Facility managers and building owners can not only benefit from knowing the history of their building’s past, but can continue to build upon their photo-database by adding new photos to capture conditions during building improvements and major maintenance overhauls. In doing so, they are making a major improvement to the value of the physical asset in a move that will lower operating costs and reduce operation risk for the life of the building.

Finding That Critical Project Photo

July 13, 2009

Imagine what it’s like to dig a hole in the sand at the beach. Hand over hand, you dig away and watch as the hole changes constantly with each shift in the sand. Whenever you see anything interesting in the hole (a sea shell, piece of sea glass, etc.) it’s covered over almost as quickly it’s uncovered.

Essentially, this experience provides a summertime analogy for tracking the work on a construction site. No matter what your role on a jobsite, you depend on knowing the condition of your area of interest continuously over the course of the project. The advent of digital photography has made it possible to inexpensively record the physical condition of the project in extreme detail. Unfortunately, recording the digital images are the easy part. After shooting hundreds (and sometimes thousands) of jobsite photos, finding that critical construction image after the fact becomes the ultimate challenge. (Raise your hand if you have a hard drive choked with project photos that are organized by project and date.)

I would like to know what you, as a construction-related professional, do to extract meaningful data from your jobsite photos. Feel free to leave your comments  and exchange ideas with your fellow readers.

Important Things to Know About Construction Photography

May 1, 2008

Here’s some interesting information to keep in mind the next time you decide to record the water proofing details way down in P5 using the same camera that you used to shoot  your kids birthday party. Thanks to our Construction Verification Supervisor Bob Gross for providing the expertise.

So it basically breaks down like this.  Most of the time we get asked what is the difference between the photos we take and photos other consultants take.

We use Canon 6.3 megapixel digital SLR’s and they have a removable lens.

Most of the other consultants including the QA\QC guy for the contractor use a simple point and shoot.

We use a full size flash (externally)  and they use the flash that is built in (to their point and shoot)

There are several major differences.

First of all the lens that we use is 55mm in diameter.  The larger the glass lens is on the front of the lens the more light it will gather.  An average point and shoot has a lens that is 15mm across if that.

Second the flash that is built into the average point and shoot is built to go 15 feet and light up two faces.  It is designed to take photos of people.   Our flash is 6 times bigger and made to throw up to 50 feet.  More light means better photos.  In a dark room (think condo before the electricity is turned on) more light is a bonus.

Third.  Our digital SLR’s have a better infrared beam built in.  Digital cameras throw out an infrared beam that measures distance a split second before taking the photo to judge distance for the autofocus feature.  Larger lens, better light, more light, better infrared beam means not only better pictures but, more in focus pictures.
