Explosives, Blasting and Vibration Specialists Come to Visit

Made time today for the folks from a consulting company to come in and make a pre-construction video of all the surfaces inside and outside of my home prior to the construction beginning this month.  I learned that they are group of consultants specializing in explosives, blasting, and vibration.  The developer, I presume, does this as matter of routine in projects like these where homes might be damaged.  I decided to make my own video after learning that the company has a formal process for either party (developer or homeowner) gaining access to the video in the future.
