Looking at their forums, their moderators are against any kind of growth or adaptation of new technologies. 

These I think are considered rookie mistakes, but I'm all about finding ways to reduce risks from human error.Has anyone else considered technological solutions to help the due diligence process?

Real- Estate  is a lot tougher game now because of technology now allowing buyers, sellers to access the market using the internet without using agents but  you do have hot areas that can support  more bodies .

Those losses can be substantial, by the way within an HVAC system-Again I doubt these technologies would hold up under scrutiny within a court of law because all it takes is one person with even a basic grasp of principles of engineering and you’d find an easy 10+% delta in these systems’ measuring abilities.

These types of places typically don't use alot of technology or have great systems, making it easy from a management perspective to turn things around.
