QC Review Process

Quality Control Review

p r e s e n t a t i o n


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?


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


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


HOW MUCH? … Time & CostQC Review : 30 minutes/Sheet Rules of Thumb $50/Sheet

SD-Schematic Design : 16 sheets : 8 hrs DD-Design Development : 24 sheets : 12 hrsCD-Construction Documents :40 sheets : 20

hrsTOTAL : 80 sheets = 40 hrs

40 hrs x $100/hr = $4000


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

QC Issues : GeneralTags & Schedules

vs.“Dumb” text

Keynotesvs.

“Dumb” text


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.)


QC Issues : General Graphics

Sheet layout Start on right Work to left

Note BlockVertical or Horizontal

All sheets : same date & deliverable description


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


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.“

1.Dim to gridlines as much as possible2.Dim to identify design intent 3.Dim using Dot vs. tick

4.Don't close dimensions5.Don't dim the tagged & scheduled

components

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


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


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)


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


G100 : Life Safety Plans Use standard LS legend & notes


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

A100's : Floor Plans Duplication of

structural info Concrete walls

Too many tags vs. Typical Note …all walls are

A3S unless noted…

(Structural) (Architectural)


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

A200 : Exterior Elevations Show :

Level lines Sections Callouts Gridlines

Const joints layout Masonry EIFS


A220 : Window Types Identify common/shared base &

head heights


A230 : Interior Elevations Mounting hgts : accessories


A300 : Building Sections Can (2) wall section(s) provide the

same info?(2) Wall Sections

Bldg Sections


A310 : Wall Sections Don’t dim scheduled items:

Windows Doors Ceiling Hgts Struct Members

Don’t repeat info: Roof slope


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


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


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.


A500's : Details Create typical details : Quantity vs. Quality Strategy for developing details

1. Identify the typical head, sill and jamb details of the exterior materials. Develop these at a larger scale (1" or 3/4").

2. Reference the model into these detail views and lock detail components to certain model content: Face of wall + gridlines, levels, etc.

3. Refer to Industry Standards: Brick industry : http://www.bia.org/html/frmset_thnt.htm Masonry advisory council :

http://eima.com/pdfs/eima%20cguide%20final.pdf Roofing : http://www.carlisle-syntec.com/index.cfm?act=details

4. Think about constructability and sequencing issues.5. Use keynotes instead of “dumb text”6. Don't identify specific sizes of other disciplines info (e.g. stl

lintels ; should be identified on structural, not arch)
