Low cost is appealing, but in the long run only if the service slots into the way people do business. MEP drawings are important as instruments of service not as physical objects. That's a much more complicated role than what PlanGrid tackled. It's product did not have to bear scrutiny from Owners, Building Officials or the Design Team. It only had to make the construction manager's job easier.
I think you didn't get it. So,the design is as per that MEP consultant or designer only who is working on the project, but using this tool it will ease out his work by making the delivery more faster, efficient and detailed, thus cutting down his effort, time and he will be able to focus more on designing and providing quality to his customers.
If it works for you, we would be glad to connect with you and discuss and try to answer more of your questions and doubts. Thanks!
So, right now we are using the software in-house thus producing projects and getting feedbacks from various customers and accordingly developing the tool, the main vision is to make it SaaS, then relationships would not be a big issue.
