Floor plans for new office and warehouse

we are looking for a 2 d/maybe 3d CAD drawing of the office on multi level. 1/ General layout, 2/ Power / CAT 5 etc 3/ escape routes and fire exits 4/ Desk allocation Computers+ monitors. This is to help with Health and safety / Planning / etc. If this is OK I propose a walk through Video to be sent as well as sketches of each room to help you understand the layout. Or do you have a standard format that you would like us to fill out. I hope you can help. Peter
