Would love to submit a sample of permit CD's per your requirements, I have not done plumbing riser diagrams in many years as I work primarily in residential construction. If awarded the bid I will provide a sample of a residential that would closely approximate your needs.
I have over 20 yrs experience in residential construction and design, here in the US. I am extremely familiar with the IRC. I have produced plans built in MD, IN, NC and work locally in VA. I am fully capable of producing a full set of construction documents, including beam, joist and structural requirements, that would be permit ready, subject to the requirements of your locality. I use Chief Architect for my CAD work and can produce 3d renderings throughout the design stages to facilitate the process. I can set up a dropbox folder to assist in transferring large documents, pictures etc. and we can have live online meetings using go to meeting. Please give me a call so we can discuss what you have to start with and how you would like to proceed. I can begin immediately.I can be found on Google+ just search Kevin R.
