I have recently been in touch with a company called Broutek Limited and had a conversation with Jose Fandos. Broutek are developing Revit MEP content for general download from their website. The website is apparently coming on line on 3rd September with content but as a member you can ask for specific content to be developed for download. They have provided me with some sample models and the quality is excellent. At last a company who is producing something that we have all been waiting for. I have been advised that membership details will be available on 3rd when the website launches.
