I WILL ASSUME YOU ARE REFERRING TO CONSTRUCTION DRAWINGS... BASIC FLOW OF DRAWING PREPARATION ON CONSTRUCTION: 1. CONCEPTUAL DRAWINGS 2. DESIGN DRAWINGS 3. DETAIL DRAWINGS OR SHOP DRAWINGS OR CONSTRUCTION DRAWINGS 4. COORDINATION DRAWINGS 5. AS-BUILT DRAWINGS - USUALLY DIFFERENT FROM PREVIOULY PRODUCED DRAWINGS BASED ON ACTUAL SITE CONDITIONS DUE TO SEVERAL ENGINEERING FIELDS COORDINATION AND CONSIDERATIONS AND CONSIDERING ARCHITECTURAL FAMOUS AND NEVER ENDING TERM "AESTHETIC" AND "SYMMETRY". OTHERS ARE EQUIPMENT LAYOUT ISSUES AND CLIENT OR CLIENT REPRESENTATIVE MODIFICATIONS WHILE ON THE PEAK OF CONSTRUCTION -- VERY VERY NORMAL. UNSEEN INFLUENCE OF SUPPLIERS: DESIGNERS(?) USUALLY RELY ON WHAT THE SUPPLIER SUGGESTS -- THIS ONE AND THAT ONE IS BETTER THAN THE CONTRACT SPECS --- THIS ONE IS GOOD FOR YOU AND GOOD FOR ME... AT THE END OF THE DAY THE DESIGNER CAN BE CALLED --- COPY & PASTE ENGINEER AND CLAIM THAT IT IS HIS IDEA AND CONFIDENTLY SIGN THE PLAN.
