WILEY Simplified Engineering for Architects and Builders (Parker/Ambrose Series of Simplified Design Guides) 12th Edition ISBN-13: 978-1118975046, ISBN-10: 1118975049 Very good condition textbook if you’re majoring in Architecture or Engineering. Used it for 2 semesters but took very good care of it. Only annotations I took are at the end of the book (some equation we used throughout the whole course). Other than that no other annotations. Usually goes for around $125. Great bang for your buck if you’re a student!
