QC Review Process
3 likes1,766 views
The document provides guidance on conducting quality control reviews of design projects. It discusses reviewing projects to identify errors and omissions, constructability issues, and compliance with standards. It recommends reviewing projects from the perspective of others involved in the project and provides tips on annotation, graphics, and ensuring consistency across design stages. Standards and checklists are important quality control tools. Allowing adequate time for review is important to catch issues early in the design process.
QC Review Process
- 1. Quality Control Review p r e s e n t a t i o n
- 2. Identify potential…. Errors & Omissions (E & O) Request for Interpretations (RFI’s) Constructability & Liability Issues Quality of Deliverables Compliance to EUA Standards Misdirected focus : Not enough vs. too much info See how EUA project teams work PM’s : project scheduling Tech Staff : interactions w/design team Team : meeting deadlines + communication Expectations : not perfect, all projects will have E&O’s WHY … QC Review Projects?
- 3. HOW … QC Review Projects? Review through the eyes of others : Contractor + Subcontractors Owner + Stakeholders (Users) Consultants Bldg Code Officials Limitations of QC Review QC Reviewer is unaware of : Client Expectations Project Budget & Design Schedule Specific Codes & Zoning
- 4. WHEN? . . . Design Stages SD : Schematic Design : conceptual design Project Planning : Schedule : Milestone Deadlines (SD, DD, & CD) Project Team : EUA Team + Design Team Project Scope : Area + Height + Site + Orientation EUA Standards : Sheet Numbering Liability Issues : Bldg Type + Site Issues DD : Design Development : refinement of the design Systems & Components : Preliminary Project Description (PPD) Phasing Strategies : Multiple Bid Packages? Technical Issues : Adjacent to Train Tracks? Acoustical Engineer? CD : Construction Documents : detail project requirements Consultant Coordination + Detailing
- 5. HOW MUCH? … Time & Cost QC Review : 30 minutes/Sheet Rules of Thumb $50/Sheet SD-Schematic Design : 16 sheets : 8 hrs DD-Design Development : 24 sheets : 12 hrs CD-Construction Documents : 40 sheets : 20 hrs TOTAL : 80 sheets = 40 hrs 40 hrs x $100/hr = $4000
- 6. QC Issues : Scheduling PM's don't always know milestone dates How can support staff work toward unknown due dates? Set a date for review sets to be final Don't send “what you have” Determine due date of all deliverables (consultants) Plan schedule “backwards” Determine deliverable due date = D Subtract Distribute Time (Dx) = D-Dx Subtract Revise Time (Dy) = D-Dy Subtract Review Time (Dz) = D-Dx-Dy-Dz
- 7. QC Issues : Scheduling
- 8. QC Review : Standard Tools Redline Color Codes Required Suggested Coordination General Comments Kudos…. Critique…
- 9. QC Issues : General Standards : Legends & Symbols L:\Design Applications\Revit\Imperial Library\Annotation\Legends and Diagrams Legends and Diagrams.rvt Symbol Legend.rfa Abbreviation Legend.rfa
- 10. QC Issues : General Tags & Schedules vs. “ Dumb” text Keynotes vs. “ Dumb” text
- 11. QC Issues : General Q : Since we aren’t sued because of standards , why focus on their noncompliance? A : The time EUA staff takes to create project or studio specific standards is time not spent on litigious issues (E&O’s, detailing, etc.)
- 12. QC Issues : General Graphics Sheet layout Start on right Work to left Note Block Vertical or Horizontal All sheets : same date & deliverable description
- 13. QC Issues : Annotation Say it ONCE … Use references notes (keynotes, general discipline notes and/or sheet notes) vs. “dumb text” Don't repeat or redraw other disciplines' info Don’t repeat specification info
- 14. QC Issues : Annotation Dimensioning NCS : "The purpose of dimensioning is to locate each element of the construction. Each wall or part of a detail must be tied to a fixed point such as a column centerline or an existing or bearing wall.“ Dim to gridlines as much as possible Dim to identify design intent Dim using Dot vs. tick Don't close dimensions Don't dim the tagged & scheduled components Do’s Don’t Do’s
- 15. QC Issues : Annotation Tags & Schedules Room Name/Number Don’t include areas (w/o a disclaimer) Door/Frames + Borrowed Lights Openings Exterior Windows Storefronts + Curtainwalls Equipment + Specialties Furniture Casework Wall Types
- 16. QC Issues : Annotation Callouts Sections : Bldg vs. Wall Enlarged plans + elev Miscellaneous North Arrow Grids (A,B,C…1,2,3…) Diagrams : Mounting hgts ADA Shelving quantities
- 17. QC Issues : Constructability Consider the sequencing of construction Once the foundation, walls and slabs (w/opngs) have been set, the locations & dims of the "arch" components are determinate on this "in-place" structure Use gridlines as common project benchmark (s) Design Intent : Implied vs. Implicit Don’t indicate Means & Methods (GC’s role)
- 18. G000 : Index Updated legends Abbreviations + symbol legend Arch and Consultant sheet series correspond Set Title : Don’t include percentages (%) “ 100% CD’s ” : no such thing Progress stamp Signature stamp
- 19. G100 : Life Safety Plans Use standard LS legend & notes
- 20. A000 : General Architecture Info A000 Bldg Systems Use of Uniformat keynoting for systems B2010-A Wall System vs. WS-# or EWS-# or W-# General Notes : Don’t repeat spec language A010 Wall Types General Sheet Notes + Wall Details
- 21. A100's : Floor Plans Duplication of structural info Concrete walls Too many tags vs. Typical Note … all walls are A3S unless noted… (Structural) (Architectural)
- 22. A100's : Roof Plans Minimum 4” diameter RD’s per roof area : (2) Maximum RD spacing : 60’ Maximum area served per RD : 2400 sf Emergency drainage : drains vs. scuppers
- 23. A110 : Ceiling Plans Coordination of MEP Linked backgrounds? Standard symbol legend Lighting & Devices Ceiling tags
- 24. A120 : Finish Plans Standard abbreviations Standard room finish tag Show design intent
- 25. A200 : Exterior Elevations Material Legends + Bldg Systems Material key (fill) vs. Keynoting
- 26. A200 : Exterior Elevations Show : Level lines Sections Callouts Gridlines Const joints layout Masonry EIFS
- 27. A220 : Window Types Identify common/shared base & head heights
- 28. A230 : Interior Elevations Mounting hgts : accessories
- 29. A300 : Building Sections Can (2) wall section(s) provide the same info? (2) Wall Sections Bldg Sections
- 30. A310 : Wall Sections Don’t dim scheduled items: Windows Doors Ceiling Hgts Struct Members Don’t repeat info: Roof slope
- 31. A320 : Stair Section & Plans Section Landing to Landing (#) of equal risers Don’t repeat plan dims Plans : Identify important dims: Clear between stringers Clear between handrails # of equal treads Landing size Handrail + Guardrails Extensions
- 32. A320 : Elev Section & Plans Section Pit Depth ? (4’-0”) Pit ladder - keynote Total Travel Distance ? Add all flr-to-flr hgts Minimum Overhead ? Hoist Beam ? To underside of beam? Plans : Don’t repeating shaft dims
- 33. A460 : Unit Plans Layouts duplicated on overall plans (A100) A100’s : Demising and "common“ walls A460’s : Interior unit info (walls, doors, elevations, etc) If (when) a change occurs in a single unit, team will have to re-issue multiple drawings on multiple sheets.
- 34. A500's : Details Create typical details : Quantity vs. Quality Strategy for developing details Identify the typical head, sill and jamb details of the exterior materials. Develop these at a larger scale (1" or 3/4"). Reference the model into these detail views and lock detail components to certain model content: Face of wall + gridlines, levels, etc. Refer to Industry Standards: Brick industry : http://www.bia.org/html/frmset_thnt.htm Masonry advisory council : http://www.maconline.org/index.html EIFS industry members association : http://eima.com/pdfs/eima%20cguide%20final.pdf Roofing : http://www.carlisle-syntec.com/index.cfm?act=details Think about constructability and sequencing issues. Use keynotes instead of “dumb text” Don't identify specific sizes of other disciplines info (e.g. stl lintels ; should be identified on structural, not arch)
- 35. A600 : Door & Frame Schedule Don’t dim scheduled door sizes Use standard door/frame names Identify glazing types (GL-#) A630 : Room Finish Schedule Standard material abbreviations
- 36. QC Support : Current Checklists Studio-specific I:\Forms Light table reviews Revit Interference check Navisworks Collision detection Newforma Compare (PDF’s & DWF’s & DWG’s)
