Drawing Checking checklist.

The drawing checking 'checklist' “Checking is a necessary evil. Checkers aren’t necessarily evil” (hill international 2004) Inherently in any creative process the ‘CONCEPT’ stage is most exciting, pleasant. Probably because the evolution of the design for the idea communicates with designer and whole process is pleasurable, which is quiet fuzzy unlike the typical working drawings. Therefore Architect who deals the project from concept till commissioning needs to have mastery in both the works. As Unchecked drawings the generally resulted in to Plan discrepancies and missing/insufficient information. Due to insufficient information causes delays. Further results in to friction between different departments and had adverse impact on the overall moral of the project Simply these two different processes can be broadly terms as Creative and mechanically creative process. Now in order to tackle the partial Mechanical process of execution drawing and detailing , one needs to have process and tools to create the error free drawings. Using Revit or similar other software’s can solve the problem but number of Revit user much lease than Autocad user. One way checking /co-ordinating the architectural structural drawings are thru check list which little bit time consuming but it can produce good result. A Checker's check list (Source - http://www.draftsperson.net/index.php?title=Shop_Drawing_Checking_Guide) 1. Is all the information in the title block correct? 2. Are the details presented in an "easy to read" manner? 2.1 All necessary sections/views present and projected properly. 2.2 All necessary dimensions present. 2.3 Any ambiguous dimensions. 2.4 All necessary annotations present and legible. 2.5 Are details in accordance with standards, job specs, and fabricator policy? 2.6 Is their redundant or excessive information on the detail? 2.7 Could I build the piece from the information shown on the detail? 3. Did I check ALL the dimensions? 3.1 Are running dimensions required? 4. Did I check the member sizes? 4.1 If size is substituted did I consider impact on adjoining members? 5. Did I check the Connections? 5.1 For fit. 5.2 For engineer’s compliance 5.3 For code compliance 5.4 For erection clearance. 6. Did I read the specs? 6.1 Is the grade of the material noted correctly for all material? 6.2 site weld testing required? 6.3 Are there special cleaning and painting requirements? 6.4 Is shop inspection required: NDT, Radiograph, MagParticle etc? 6.5 Are weld procedures required? 6.6 Should any members or parts of members be noted "no paint"? 6.7 Is special testing required for the bolts? 6.8 Load indicator washers required? 6.9 Is shop assembly required? 6.10 Is Cambering required? 6.11 Is Punching dis-allowed or reaming required? 7. Is each shipping piece shippable? over length, over width, overweight. 8. Are all the quantities correct? 9. Does the bill of material match the dimensions on the drawing? 10. Are the erection drawings presented in an "easy to read" manner? 10.1 Are the marks in the proper location? 10.2 Do the columns have the correct direction orientation? 10.3 Is there a "North Arrow" on the plan? 10.4 Are all necessary dimensions shown correct on the plan / elevation views? 10.5 Are all member sizes shown correct for each member? 10.6 Is all field welding that is required shown correctly? 10.7 Are elevations at top of floors, roofs, landings etc. shown correct? 11. Are the bolts sizes, grades, and quantities correct? 11.1 Are oversize washers required for the holding down bolts? 11.2 Is there and special bolt requiremen

ts? 12. Did I thoroughly study all the design drawing to see if all the members in the in the scope of the fabricators contract have been detailed? 12.1 Lintels. 12.2 Deck support angles. 12.3 Embedded plates. 12.4 Ships ladders, trash gate frames, bollards, stairs, railings. 13. Is there a better, less expensive way to fabricate any of the pieces? 14. Are any pieces detailed beyond the capabilities of the fabricator's equipment? 14.1 Are bend lengths and thickness within machine capacity? 14.2 Shop splices shown where required due to machine/material limitations? 14.3 Are punch sizes available for the slotted and round holes shown? 14.4 Are any pieces beyond lifting capacity of the shop? 15. Did I co-ordinate interface with other trades (holes for owner machinery, holes for wood, match holes in existing members)? 16. Did I put a lot of my unwanted opinion into marking up the detail (did I mark it up the way I would have detailed it) or did I check to see only if it was right or wrong (if it works let it go)? 17. Establish marks for typical parts such as base plates, cap plates, stiff plates, shear plates , connection angles. 18. Layout and confirm connections shown on design work... special concentration to brace bays, rafters or trusses or girders and parts connecting to them. (
