We're coordinating with K. Rudivic on M&E part (initial comment was that the M&E requirement are met by the design that correspond to MI's requirement) and will get back to you soon. On architectural part, it doesn't seem to have much impact on design work except some specifications of materials while we cannot provide the estimated cost for modification and may need APK to respond on item 5. Item 2 should be a minimum at cost unless you need the whole set reprint.
