The Quality Loop, #CONSTRUCT #T03

The Worm Ouroboros from Atalanta Fugiens, Michael Maier, 1617

Quality Assurance and Quality Control are terms frequently used interchangeably, but which actually represent very different aspects of Quality requirements. 

A clear understanding of the relationship between Assurance and Control is essential to effective specification of the duties and responsibilities of the parties in construction. The overall level of quality required for the project determines the ultimate quality requirements in the specifications.

Understanding the concept of Quality Assurance and Control as a Quality Loop, where the work result of one section becomes the substrate for the next section allows determination of the correct location to specify quality requirements.

These clear descriptions of project quality assist in the identification and correction of non-conforming work, as well as the parties responsible for their correction. and the ability to enforce the requirements at the proper time in the construction sequence.

Learning Objectives:

Explain the difference between Quality Assurance and Quality Control.

Determine which Quality Requirements should be specified in Division 01, and which should be specified in the Technical sections.

Employ the concept of the "Quality Loop" where the interrelationships of Work Results mean that one Work Result becomes the substrate for another, clarifying coordination between related sections.

Analyze and deconstruct building assemblies to formulate the Quality Requirements of the assembly and specify them in the appropriate Work Results sections.

Programs for CONSTRUCT 2013

I am honored this year to present three original education sessions at the 2013 CONSTRUCT show / CSI convention in Nashville.  This post is to set forth the titles, topics and session codes for the sessions.  I will discuss the contents and educational goals of each in forthcoming posts, please stay tuned.

If these sessions don't look interesting to you, please take a look at the convention schedule, there is a large number of presentations by some first-rate speakers, it is an excellent educational opportunity.  I hope to see you in Nashville in September.

San Francisco CSI Profair

Dance to the Music of Time, Nicolas Poussin, 1640

San Francisco CSI is holding their annual Profair event at the UCSF Mission Bay Conference Center, 1675 Owens Street, San Francisco on May 8, 2013.

I will be presenting a brief talk on specifying Division 01, "The Hub of the Wheel".  One of those wheels can be seen in the painting Dance to the Music of Time above, held up by Apollo in the chariot.

Anne Whitacre FAIA, CCS, Associate AIA will be discussing “Specifying Beyond Platinum: Working with Red Lists, Pharos, and Living Building Challenge Projects”, pointing the directions beyond LEED, CAL-Green and garden-variety sustainability.

Michael Chambers FCSI, FAIA, CCS, SCIP will offer "“UniFormat™: Preliminary Project Descriptions, Cost Estimates, and Post-Occupancy Maintenance", to round out the technical sessions.

For more information, or to enroll for the presentations, see http://sanfrancisco.csinet.org.

Don't delay, the wheels are turning and the music is playing, make sure you have a chair when it stops.

The Beginning of Specifications... and More

 I am very honored to be invited back to California Polytechnic University at San Luis Obispo, College of Architecture and Environmental Design (CAED) to present to the students on the relationship of architecture and construction specifications on Thursday, 25 April.

This year we will discuss a little of the beginning of specifications and how the written component of construction documents evolved out of the early contracts for construction.  The slide above is a brief preview of the central content.

Thanks to Jim Doerfler, Associate Department Head of CAED for the opportunity to address the students and share CSI principles and specification trivia with the next generation of architects.

The next day, Friday, 26 April, the CAED students are presenting the Cal Poly Construction Forum, with sponsorship by CSI, with a focus on sustainable materials and innovative techniques.

DTR Consulting Services is fortunate to be involved with the Human Needs Project, creators of an innovative approach to help people in need of basic utilities and facility services that the developed world takes for granted.    

This project by architect Ken Kao of Kao Design Group of Somerville, MA http://www.kaodesign.com, constructed by Redhorse Constructors of San Rafael, http://www.redhorseconstructors.com, embodies new thinking about human needs and exciting applications of ordinary materials to offer a promise of better circumstances to the people of Kibera, Nairobi, Kenya.

A brief presentation will outline the architectural response to the social and environmental factors in the community of Kibera and discuss the engineering and design effort involved to address the concerns of the residents.

Please consider visiting the Human Needs Project, http://www.humanneedsproject.org, to learn more about their plans for the future.  Donations are gladly accepted at their site.

The Code of Specifications

Do construction specifications require translation?

Often construction specifications seem as oblique and inaccessible as these hieroglyphic carvings in the hypostyle hall at the Great Temple in Karnak, Egypt. (Engraving by Josef Durm, 1914)

Is there a correct way to encode the information for a new product into the "CSI Format"?

(Fragment of the Papyrus of Ani, ca. 3500 BC)

Is there a "CSI Format", and how does it work?  Can it help you write better specifications, or even read and understand specifications more easily?  Is Cleopatra discussing specifications with Mark Antony? (The Banquet of Cleopatra, Giovanni Batista Tiepolo, 1746)

Join us on Tuesday, November 13, 2012, 1:30 to 3:30 p.m @ North Coast Builders Exchange
1030 Apollo Way, Santa Rosa.

This presentation qualifies for AIA HS&W learning units.

Changing Horses Mid-Stream: Managing Substitutions

Consider attending the Santa Clara Valley Chapter of CSI next meeting, 1 November 2012, at Biltmore Hotel & Suites, 2151 Laurelwood Road, Santa Clara.

The topic will address Managing Substitutions, Changing Horses Mid-Stream.

Few construction administration procedures inspire such strong emotions as Substitutions.  

Architects seem to despise them, while Contractors seem to dote on them.  

Owners are concerned that the project quality is maintained, but are beguiled by possible cost savings or schedule acceleration.  

Substitutions have the potential to disrupt a project, or confer great benefits.

Substitution Procedures are primarily a means of Quality Assurance, to prevent un-"equal" products from undermining the design intent.  But How Equal is Equal?  And who decides?

What actions can the A/E take in product selection and specifications to reduce substitution requests or to deal effectively with those that arise?  

What risks arise to the parties in construction from substitutions, authorized or not?  

What actions are appropriate to allow acceptable substitutions to be incorporated into the Work while maintaining the risk allocations of all the parties?

Can Construction Documents be crafted to resolve these issues fairly for all the parties?

Join us for the discussion.  Details are here >> http://www.csiscv.org/

Today's painting is "The Horse of Alfonso Ugarte" by Agostino Marazzani Visconti, 1905.  The rider is not exactly mid-stream, but seems to be considering a change of steeds.  Image courtesy of Wikimedia Commons, believed by this author to be in the public domain since it was published before 1923.

High Concept, Low Tech

Today's post looks at a striking design effect that was very easy to implement.  Proof that simple things can still be uplifting, and 3D modeling of biscuit-shaped forms is not always needed.

The photo shows the ceiling of the escalator lobby in a new department store in the Bay Area.

The little sparkly bits are nothing more than acrylic film tied off with monofilament plastic line (fishing line), which is suspended from the ceiling in long strands.

The plastic film is sidelighted by the clerestory windows and the whole thing sways gently in the HVAC breeze.


The effect is mesmerizing and really easy to pull off, although it was probably tedious to assemble thousands of pieces of film on hundreds of strands.  I am not sure if this was part of the architecture, or an art installation that came later, but it is very effective.  An excellent design effect with extreme economy of means.  This would be fun to specify.

High Concept, Low Tech.

Best Regards.
