am pleased to be writing my first letter as President of the ALA. It is an honor to be your new President and I look forward to serving you over the next couple of years.


First, I would like to thank outgoing president Steve Pate for his leadership and tireless efforts in moving ALA and its agenda forward over the last 7 years. Steve presided over many changes during his tenure some of which include: a rapid growth in membership to almost 1300; the incubation and continued growth of five chapters; the opening of ALA’s new headquarters in Barrington, Illinois; the addition of the ALA short form contracts; the new upgraded ALA website (ALAToday.org); and circulation growth and the redesign of the ALA Magazine. Steve received the ALA Lifetime Achievement Award at the recent Design Awards Banquet. On behalf of all of ALA’s Members and the Board of Directors, Congratulations Steve on a hard earned and much deserved award! Additionally, Peg McLean, our longtime Executive Director, received the ALA Outstanding Service award. Also much deserved - Congratulations Peg! Peg is owed a great debt of gratitude for doing much of the heavy lifting since the beginning of ALA, more recently with the help of Kay and Lisa. After many stalled attempts (the board refused to let her go!), Peg will be working her way into retirement over this next year and Joanne Sullivan, our new Executive Director, will be taking the helm. Welcome aboard Joanne!

As I mentioned, the Design Awards Banquet was held Friday, November 12th at Medinah Country Club and was attended by many members and guests. It was an outstanding event held at an unbelievable venue. With over 100 Design entries literally from all over the world, the event showcased the incredible depth of talent and expertise of ALA Members. Please take the time to review the 31 winning designs which are showcased in this issue. The design entries were all exciting and ran the gamut in terms of building types and architectural styles. All of the entries were on display at the Awards Banquet for review during the hosted reception prior to the dinner and program. Our emcee for the evening, WTTW Host and Producer Geoffrey Baer, did an excellent job. His knowledge of history and architecture was both entertaining and informative. Thank you Geoffrey! Start preparing your submittals for next year’s Design Awards Program. It will be here before you know it! Thanks also to the Design Awards Committee, all of the Jurors and to our staff for a job well done. Lastly, on behalf of the entire Board of Directors and staff, I would like to wish all of our Members a happy, healthy and joyous Holiday Season and a safe and prosperous New Year!

BUILDING CODE MYTHS & FACTS Some of this might seem elementary, but you would be surprised how many calls I receive about these questions. • STUD SPACING - Do all studs have to be spaced at 16" or 18"? No, as long as they hold the load they are designed for. • NON-COM WOOD - There is NO such thing as non-combustible wood. There is FRTW (fire retardant treated wood), but is does not comply with the code definition of non-combustible. • PANIC HARDWARE - Only required to use group A and E with more than 50 persons and all High Hazard use groups. It is not required on all exit doors. • EXITS SIGNS - Only required when two or more exits are required, not over every door. • DELUGE SYSTEMS - A row of fire sprinklers to protect an opening is not a deluge system. A deluge is when ALL fire sprinklers discharge at one time with open heads held back by a detection system (slave) that activates the excessive deluge of water. • GOVERNMENT BUILDINGS - They may not be exempt for building codes, permits fees and inspection. • SPRINKLER INCREASES - Height and area increases apply only when the entire building is protected by fire sprinklers. • SPRINKLERS CREATE WATER DAMAGE - If you think fire



sprinkler discharges a lot of water, just wait and see how the fire department attacks a fire in a non-sprinklered property with multiple hoses that discharge 250 g.p.m. each. SINGLE EXIT BUILDINGS - Travel distance is limited to Table 1021.1 (2009 IBC) based on use group so there will always be a dead end corridor. They don’t require Exit signs nor panic hardware due to their limited occupancy permitted in the code. OCCUPANCY LOAD CALCULATIONS - The code bases it on allowable number of persons. Actual number can be used under certain conditions such as a fixed seat movie theater or an automated warehouse with a small staff. A use group that wants to base their occupant load below the sprinkler threshold requirement (i.e., restaurant) by indicating just 99 seating places does not comply with the allowable area if it can accommodate additional persons. ALL WALLS ARE NOT FIRE WALLS - Fire walls must be noncombustible (except Type 5 construction), structurally independent, able to allow collapse on either side and has all doors, windows, ducts, vents protected. The minimum rating is two hours. CONFINE & EXTINGUISH - Those are the basis of the codes. Either contain the hazard or extinguish it. Remember - 80% of the building code is fire and life safety.

Use Caution When Certifying Contractor’s Applications for Payment By James K. Zahn, FALA, FAIA, Esq.

have noticed an alarming increase in the number of lawsuits filed against Architects that include fraud counts. Owners are getting more aggressive in holding their Architects responsible for allegedly improperly certifying Contractor’s Applications for Payments that oftentimes includes payment(s) for what the Owner later discovers to be defective work. After a payment has been made, some Owners may argue that the Architect’s Certification for Payment constituted a fraudulent misrepresentation that the Contractor was entitled to the certified amount, and that the Owner, in reliance on the certification, made the payment for the defective work to his detriment. The Owner is now seeking to recover the overpayment for the defective work from the Architect. It is important to note that the American Institute of Architects ("AIA") and the Association of Licensed Architects ("ALA") agreement forms each qualify the Architect’s approval of the Contractor’s Application(s) for Payment, to be made "to the best of the Architect’s knowledge, information and belief." None of the AIA or ALA documents guarantee perfection or that the completed construction will contain no latent defects. AIA, and ALA, Owner / Architect Agreements each specifically define the role of the Architect relating to the approval or rejection of a Contractor’s Application for Payment. AMERICAN INSTITUTE OF ARCHITECTS DOCUMENTS: The following excerpts are taken from the American Institute of Architects, "Standard Form of Agreement Between Owner and Architect, AIA Document B101-2007: § 3.6.2 EVALUATIONS OF THE WORK § The Architect shall visit the site at intervals appropriate to the stage of construction … to become generally familiar with the progress and quality of the portion of the Work completed, and to determine, in general, if the Work observed is being performed in a manner indicating that the Work, when fully completed, will be in accordance with the Contract Documents. However, the Architect shall not be required to make exhaustive or continuous on-site inspections to check the quality or quantity of the Work. On the basis of the site visits, the Architect shall keep the Owner reasonably informed about the progress and quality of the portion of the Work completed, and report to the Owner (1) known deviations from the Contract Documents and from the most recent construction schedule submitted by the Contractor, and (2) defects and deficiencies observed in the Work.... § 3.6.3 CERTIFICATES FOR PAYMENT TO CONTRACTOR § The Architect shall review and certify the amounts due the Contractor and shall issue certificates in such amounts. The Architect’s certification for payment shall constitute a representation to the Owner, based on the Architect’s evaluation of the Work as provided in Section 3.6.2 and on the data comprising the Contractor’s Application for Payment, that, to the best of the

Architect’s knowledge, information and belief, the Work has progressed to the point indicated and that the quality of the Work is in accordance with the Contract Documents.... § The issuance of a Certificate for Payment shall not be a representation that the Architect has (1) made exhaustive or continuous on-site inspections to check the quality or quantity of the Work, (2) reviewed construction means, methods, techniques, sequences or procedures, (3) reviewed copies of requisitions received from Subcontractors and material suppliers and other data requested by the Owner to substantiate the Contractor’s right to payment, or (4) ascertained how or for what purpose the Contractor has used money previously paid on account of the Contract Sum. ASSOCIATION OF LICENSED ARCHITECTS DOCUMENTS: The following excerpts are taken from the Association of Licensed Architects, "Short Form Owner / Architect Agreement For Architectural Services, ALA Document OA4-2010: 3.4.1 SITE OBSERVATION. The Architect shall visit the site to observe if the construction is generally in accordance with the construction documents.... 3.4.4 REVIEW OF CONTRACTOR’S REQUESTS FOR PAYMENT. The Architect shall evaluate the Contractor’s requests for payment, including supporting data, and certify the amounts due the Contractor for work, products, and materials installed in the project. The Architect’s Certification for Payment represents to the Owner, that based upon the Architect’s evaluation of work installed and data presented for payment, to the best of the Architect’s knowledge, information and belief, the Contractor is entitled to payment. Recently, some Owners have determined that certain latent defects existed at the time the Contractor’s Application for Payment was processed and certified by the Architect. They now claim the Architect certified the Contractor’s Application for Payment to their detriment, ignoring the wording that the certification was made to the best of the Architect’s knowledge, information and belief. Such certification, the Owner now claims, constitutes a fraudulent misrepresentation of the facts that induced the Owner to make the payment to the Owner’s detriment. Fraudulent misrepresentation is also known as common-law fraud. (Continued on page 8)



LEGALISSUES (Continued from page 7)

COMMON-LAW FRAUD In order to state a cause of action for common-law fraud, each element must be pleaded with specificity. Those elements are (1) a false statement of material fact was made; (2) the party making the statement knew or believed it to be untrue; (3) the party to whom the statement was made had a right to rely on the statement; (4) the party to whom the statement was made did rely on the statement; (5) the statement was made for the purpose of inducing the other party to act; and (6) the reliance by the person to whom the statement was made led to that person’s injury. In order for a cause of action for common-law fraud to survive, the Plaintiff must prove each of the following six elements of common-law fraud: (1) That the Architect made a false statement of material fact. An Architect states that "to the best of its knowledge, information and belief, the construction is in accordance with the contract documents and the Contractor is entitled to the requested payment." After this statement is made, it is later discovered that defective construction exists which should not have been paid for. The Owner now claims that the above is a false statement of material fact. (2) That when making its statement, the Architect knew or believed that its statement was untrue. The Plaintiff must be able to prove that the Architect did not believe, or actually lied, when making the statement. This is a very difficult thing to prove. What would the Architect gain from doing this? (3) The party to whom the statement was made had a right to rely on the statement. The very reason the Architect certifies the Contractor’s Application for Payment is to provide his professional certification to an Owner that the work either conforms or does not conform to the Contract Documents and that the Contractor is entitled or not entitled to payment for same. (4) The party to whom the statement was made did rely on the statement. It is expected that the Owner will rely on the professional certification of the Architect. (5) The statement was made for the purpose of inducing the other party to act. The purpose of the certification is to induce the Owner to take the advice of the Architect and pay the certified amount, or in some cases, pay nothing at all on this specific Application for Payment. (6) The reliance by the person to whom the statement was made led to that person’s injury. The Plaintiff will argue that his reliance on the Architect’s certification induced him to pay the Contractor for the work now determined to be defective construction. The cost to remove and replace the work correctly is the amount of damage that the Owner is claiming. The Owner is placing the risks of construction latent defects upon the Architect, and not upon the Contractor, who is responsible for them. If any of the above elements cannot be proven, the entire cause of action for common-law fraud will fail. WAYS TO LIMIT YOUR LIABILITY EXPOSURE One way to limit your potential liability exposure as an Architect is to avoid reviewing and certifying Contractor Applications for Payment. In



Design/Build situations, the Architect is engaged by a Design/Build entity which is responsible for the costs of construction of the project. In such situations, the Architect usually does not review and certify Contractor Applications for Payment. By not certifying Applications for Payment, the Architect’s potential liability exposure is greatly reduced. In projects where a Construction Manager is engaged by the Owner, the Construction Manager will review the Contractor’s Applications for Payment, even when the Architect is also reviewing them. If at all possible, attempt to negotiate out of reviewing and certifying the Contractor’s Applications for Payment. You can argue that the Construction Manager is more knowledgeable of current construction costs and in a better position to protect the Owner from overpayments. Why have two entities doing the same work and have the Owner pay twice? If you cannot convince the Owner to delete certifications from your contract, your liability exposure is still reduced due to the Construction Manager also reviewing and certifying the Applications for Payment. In a traditional design, bid, build project, the Architect will most likely still review and certify the Contractor’s Applications for Payment. It is imperative that the Architect strictly adhere to the specific contractual requirements of its contract with the Owner when performing such reviews and certifications. Failure to do so may result in a lawsuit by the Owner attempting to recover any overpayments made as a result of certifications by the Architect for completed work, that later is discovered to be defective work requiring replacement. An Architect should always qualify that the certification of a Contractor’s Application for Payment is made to the best of the Architect’s knowledge, information and belief. It is not an assurance of perfection, or a guaranty that no latent construction defects were incorporated into the actual construction of the project. Another way to limit potential liability exposure, as a result of your involvement in certifying Contractor’s Applications for Payment, is to urge the Owner to engage a title company to handle all of the construction payouts. By using a title company to process the construction payouts, both the Owner and the Architect will benefit by having an experienced third party review the Contractor’s Applications for Payment, The Contractor’s Sworn Statements, and all supporting paperwork, including partial and final waivers of lien from the various contractors, subcontractors and material suppliers, prior to making any actual payouts. The use of a title company for processing construction payouts is a relatively low cost process that provides great benefits to the Owner.

Forensics and Innovation by Robert G. Stanton, CPCU, ARM, RPLU

n this age of Green/Sustainable design, design professionals are being asked to be more innovative in design work. The push for innovation is coming in the midst of a huge market downturn in which there are a great number of design professionals who are not working. Many design professionals are looking to earn income by offering to perform forensic work given the lack of other types of projects. This scenario begs two questions: 1) Is the forensic expert being retained to review the design qualified to provide expert testimony as to the adequacy of the design? 2) How will any form of litigation affect the status of the design as "innovative?" The first question addresses whether an effective defense can be mounted against claims asserted against innovative designs. The second question is more of an "indirect" cost of claims related to innovation claims. Before delving into answering the questions, the historic approach to defending a claim frequently entailed the design professional citing other projects in which the designs or components were used without problems. With innovation, this may not be possible. The performance projections of an innovative design will be based on theoretical or empirical research and not field application. This may be more difficult for a jury to understand. There will be a greater emphasis of the "battle of experts" that will determine whether the standard of care has been met. Recently, there was a claim in which a designer had conceived and designed an air handling system that was considered to be innovative. Due to a series of misunderstandings where the contractor and owner/client (owner) began to second guess the design, the owner opted to retain an expert to review the design. Unfortunately, the owner selected expert was a direct competitor of the designer, and found all types of problems with the designer’s work. The fact that the

owner’s expert was a competitor of the designer was a problem in and of itself. The real issue was the problems seemed to stem from the owner’s expert not truly understanding the design itself. A claim ensued. To attempt to address the concerns the owner had relative to the design, our intrepid designer retained his own expert to review the work and render an opinion. The designer indicated there were probably a handful of experts in the country who would truly be able to understand what he was trying to accomplish with his design. One was selected from the handful the designer named. Unfortunately, the designer’s expert stated that, "I really don’t truly understand all the intricacies and nuances of the design, but the calculations and physics of the work appear correct." Obviously, this was not as definitive an opinion as was the owner’s expert, and did not really go far to assist in the defense of the claim. If a design or component of a design is truly innovative, there may be a concern that there may not be qualified experts to address the design concerns, and that there are no field applications that can be used to demonstrate the adequacy of the design. A scenario may be created in which there will be greater hurdles to overcome to determine if the design has met the standard of care. The science behind the design will be of paramount importance to the determination of whether the design has met the standard of care. This may also result in a shifting of the standard of care as there is really a small group of "reasonable" designers who can do this type of work. Who will probably profit from this type of scenario…who else, the attorneys. Taking the above scenario, we have a situation where there is our designer, the owner’s expert and the designer’s expert having extensive access to an innovative design. With such expansive access not only to the design, but to the science behind the design, the designer has a realistic concern about losing its competitive advantage over the market because of its innovation. In this case, it becomes even more

“The push for innovation is coming in the midst of a huge market downturn in which there are a great number of design professionals who are not working. Many design professionals are looking to earn income by offering to perform forensic work given the lack of other types of projects.”



disconcerting a situation. The designer’s competitor now has access to the design and the science behind the design. Even if the competitor cannot recreate the innovation with adequate variations to ensure no violation of the patents, the inside knowledge gained will allow the competitor to formulate strategies to attack the innovations in competitive situations. In a world where most people fear change, any concern relative to anything new can create substantial problems for the innovator in gaining the acceptance of the change with the general public. To combat this, there are some steps the designer can take to attempt to protect itself from attacks on its innovative design. First, the designer must get the owner to be committed to the innovation, and that commitment must be with knowledge of both the benefits and risks associated with truly innovative design. This commitment should be incorporated into the contract if possible. If this cannot be accomplished, the discussions relative to the benefits and risks should be memorialized and communicated to all the parties involved in the project. This commitment should also be agreed to by the contractors as well as the owner. As HVAC contractors frequently have design responsibilities on projects, the buy-on by these contractors is even more vital. Second, the science behind the innovation will be essential. Therefore, extra care should be given to ensure the calculations used for determinations of loads or other operating criteria are workable and verifiable. This is a quality control issue that needs to be handled by the design firm.

Third, a designer should have a short list of experts they believe can properly offer expert opinions as to the standard of care in the creation of the innovative design. Also, the designer should share this list with the owner so that the list can be vetted and there can be a buy-on to this group by the owner before a problem arises. If possible, there should be a fairly extensive confidentiality agreement to be executed by any expert relative to the information gathered in the investigation into the adequacy of the innovative design. The confidentiality agreement should have specified damages for any violation of the agreement. Of course, this clause would be more effective if a proper copyright or patent is in place. With the enhanced demand for innovation in conjunction with the new delivery systems such as BIM and integrated design, preplanning for issues that may arise is becoming more essential to the design professional than ever. Two major issues related to innovation are the client buy-on to the benefits and risks associated with innovation, and the chance of problems associated with the retention of experts. These recommendations may prevent the potential of loss on innovative designs as well as reduce the chance of leakage of your innovative designs to other parties.

Reaching to the Top! by Kimberly Paarlberg, RA, and Jay Woodward, RA, ICC Senior Staff Architects

ompliance with the new federal standards for accessibility will be required as of March 15, 2012. The 2009 edition of the ICC A117.1, Accessible and Usable Buildings and Facilities will be referenced in the 2012 International Building Code. So there will be a learning curve for all architects and contractors with some of the new requirements. Knowing the history or reasons behind revisions will help when determining what is important when dealing with alternatives. History I (Kim) recently spent some time in the archives at the University of Illinois. What motivated my research is that the A117.1 standard will be 50 years old in 2011. The first A117.1 came out in 1961 and was reaffirmed in 1971. I looked through the files of the original development committee and the personal files of Dr. Tim Nugent. Nugent served as the first secretariat and then chair of the committee for a number of years. The research that he did with students at the U of I was one of the primary resources for the ‘building blocks’ used for accessible design. Physical therapists, mechanical engineers and students with disabilities worked together to gather ergonomic research to develop criteria for clear floor space, turning space, reach ranges, ramps, etc. I found it interesting that what the students could actually achieve was greater than the suggested minimum requirements. For example, the side reach range measured was 54 inches to 78 inches, with an average of 60 inches (1961 A117.1 Section 3.3.1). The 54 inches that ended up in ADAAG and later editions of the A117.1 as the high end of side reach was what was ‘comfortable’ for all tested subjects. Nugent was the founder of the Division of Disability Resources and Educational Services for the U of I. His responsibilities included looking for ways to make the entire campus accessible so students could participate in all activities offered by the University. Given the school had over 200 buildings on over 1000 acres, and has some of the oldest college buildings in the state, this was quite a job assignment. In March the University named a newly constructed residence hall in honor of Nugent, another example of how the work Nugent nurtured continues to grow and expand. Reasons for the Revisions The International Code Council (ICC) and the U.S. Access Board continue to work together on coordination and clarifications. Below are the sections dealing with side reach for the 2010 Standard for Accessible Design and the 2009 ICC A117.1.



2010 Standard for Accessible Design The Department of Justice (DOJ) officially published the 2010 Standard for Accessible Design in the Federal Register on Sept. 15, 2010. While a designer can choose to use the new requirements now, compliance will be required by March 15, 2012. The link to the 2010 standard and guidance document is: http://www.ada.gov/2010ADAstandards_index.htm. This federal standard will match the 1998 and 2003 ICC A117.1 revisions that limit the side reach from 15 inches to 48 inches. This is different from the 1991 ADAAG, which allowed for a side reach of 9 inches to 54 inches. Both documents revised the side reach based on statistical data provided by an organization called Little People of America. Their concern was for persons with limited reach having access to controls, ATMs and fuel pumps. 308.3 Side Reach. 308.3.1 Unobstructed. Where a clear floor or ground space allows a parallel approach to an element and the side reach is unobstructed, the high side reach shall be 48 inches (1220 mm) maximum and the low side reach shall be 15 inches (380 mm) minimum above the finish floor or ground. EXCEPTIONS: 1. An obstruction shall be permitted between the clear floor or ground space and the element where the depth of the obstruction is 10 inches (255 mm) maximum. 2. Operable parts of fuel dispensers shall be permitted to be 54 inches (1370 mm) maximum measured from the surface of the vehicular way where fuel dispensers are installed on existing curbs. 308.3.2 Obstructed High Reach. Where a clear floor or ground space allows a parallel approach to an element and the high side reach is over an obstruction, the height of the obstruction shall be 34 inches (865 mm) maximum and the depth of the obstruction shall be 24 inches (610 mm) maximum. The high side reach shall be 48 inches (1220 mm)

maximum for a reach depth of 10 inches (255 mm) maximum. Where the reach depth exceeds 10 inches (255 mm), the high side reach shall be 46 inches (1170 mm) maximum for a reach depth of 24 inches (610 mm) maximum. EXCEPTIONS: 1. The top of washing machines and clothes dryers shall be permitted to be 36 inches (915 mm) maximum above the finish floor. 2. Operable parts of fuel dispensers shall be permitted to be 54 inches (1370 mm) maximum measured from the surface of the vehicular way where fuel dispensers are installed on existing curbs. 2009 ICC A117.1 The A117.1 development committee strives to clarify requirements as well as address coordination items. Jay wrote about the revisions for side reach in the Significant Changes to the A117.1 Accessibility Standard. Below are some excerpts on side reach. Revisions to the A117.1 text are shown in legislative (i.e., strike out/underline) format. 308.3 Side Reach. 308.3.1 Unobstructed. Where a clear floor space complying with Section 305 allows a parallel approach to an element and the side reach is unobstructed, edge of the clear floor space is 10 inches (255 mm) maximum from the element, the high side reach shall be 48 inches (1220 mm) maximum and the low side reach shall be 15 inches (380 mm) minimum above the floor. Exception: Existing elements that are not altered shall be permitted at 54 inches (1370 mm) maximum above the floor. In Section 308.3.1, the intent is to provide clarification as to where the clear floor space must be located to be considered an unobstructed reach to an element or control. For an "unobstructed" reach, the clear floor space must be located within 10 inches horizontally, and any obstruction within that space must be 34 inches or less in height. This revision was not intended to create any technical changes but was considered more as a clarification of Figures 308.3.1 and 308.3.2. Adding into the exception the text "that are not altered" helps limit the application. Earlier editions of the A117.1 standard and the original ADAAG permitted a 54-inch high side reach. Because of this earlier allowance, numerous elements in existing buildings may be located above the maximum height that is required in new construction. If an existing control is relocated, than it must meet new construction limits. 308.3.2 Obstructed High Reach. Where a clear floor space complying with Section 305 allows a parallel approach to an object element and the high side reach is over an obstruction, the height of the obstruction shall be 34 inches (865 mm) maximum above the floor and the depth of the obstruction shall be 24 inches (610 mm) maximum. The high side reach shall be 48 inches (1220 mm) maximum above the floor for a reach

depth of 10 inches (255 mm) maximum. Where the reach depth exceeds 10 inches (255 mm), the high side reach shall be 46 inches (1170 mm) maximum above the floor for a reach depth of 24 inches (610 mm) maximum. Exception: At washing machines and clothes dryers, the height of the obstruction shall be permitted to be 36 inches (915 mm) maximum above the floor. The addition of the exception is the primary change within this section. The exception is included to conform to the 2010 Standard, which allow washers and dryers to exceed the maximum height for an obstruction. With the popularity of frontloading machines with front controls there are more options available. Additional revisions were made in Section 611 to address the front-loading laundry equipment. Since the allowances for reach over an obstruction did not change, an exception similar to Section 308.3.1 is not needed. Conclusion: The 2010 Standard and the A117.1 sometimes differ because of style, approach and methods of enforcement. For example, 2010 Standard, Section 308.3, Exception 1 is dealt with within the text in ICC A117.1, Section 308.3.1. If anyone is interested in providing a code change proposal for fuel dispensers to match the second exceptions in the 2010 Standard for Sections 308.3.1 and 308.3.2, I would suggest a possible code change proposal to 2012 IBC Section 1109.14, Fuel-dispensing systems. Code change forms can be found on the ICC website at http://www.iccsafe.org/cs/codes/ Pages/2012-13_Cycle.aspx. Deadline for submissions is January 3, 2012. ICC code development staff is always available to assist you through the process if you are interested!

The Architect as Expert Witness: A Survival Guide by Bob Greenstreet Dean, School of Architecture and Urban Planning, University of Wisconsin-Milwaukee rchitects can turn their hands to a number of professionally related fields, which is a useful attribute when times are hard. We possess a broad perspective of the entire design and construction process, an ability to problem solve and think creatively on our feet and an innate knack of being able to talk intelligently about such subjective issues as space and design. For these reasons, architects can become very useful expert witnesses, and a number of our colleagues have developed rewarding sidelines by providing reports and testimony for either the plaintiffs or defendants in construction related disputes, of which there are regrettably no shortage. However, as attractive as the field might seem, it must always be remembered that, when we enter the realm of law, we are out of our natural environment. We are in the combative world of attorneys whose task it will be to question and, if possible, undermine and call into question the reliability of our evidence. Attorneys were trained to do this, they do it every day and they

are usually very good at it. Consequently, a few safeguards might be advisable before you venture into their world to ensure that your role as an expert witness remains a credible one and that your opinions remain as defensible and as valuable to your clients as possible. Polish Your Credentials Being selected as an expert witness will depend to a great extent on the architect’s credentials, which must be extensive enough to impress a judge, jury or arbitrator and signify that his/her opinion is one worthy of consideration. Degrees and diplomas from reputable academic institutions provide a solid foundation of credibility, which should be backed up with details of sufficient practical experience relevant to each case in question. Details of special training courses and ongoing continuing education are also helpful. If you’ve undertaken any teaching, have written any papers or articles or have given lectures within your field of expertise, all the better. Make sure that you are scrupulously accurate in outlining your professional profile – if opposing counsel finds any exaggerations or inconsistencies in your claims, your credibility is diminished before you even get to your testimony or report – and make sure your resume is professionally balanced. If you appear to do little else beyond expert witness work, you are vulnerable to claims that you are nothing more than a ‘hired gun’ who will say whatever is required for compensation, regardless of your real opinion. An architect who is primarily involved in architectural practice and who does the occasional expert report can arguably demonstrate a greater degree of professional detachment and less financial dependency and can therefore be more convincing as an expert witness. Expert witnesses can be selected based upon prior reputation, by a simple web search that will locate any earlier writings or websites, or through agencies that specialize in expert witness placement. In any event, you as a potential expert witness are likely to be interviewed before selection to determine if you are appropriately qualified for the case in question, if you possess the right characteristics of a convincing expert witness and if your opinions on the case in question are helpful to the lawyer and his/her client. If you have reports rendered in previous cases or articles written on similar construction issues, you might want to share them with the attorney, both to demonstrate your writing ability and your general approach to construction disputes. If you have expressed an opinion in your previous work that conflicts with the required direction indicated in the current case, your attorney will want to know in case it is discovered by opposing counsel and used to undermine your latest opinion.

An Introduction to Thermal Stress in Float Glass by Christopher Barry, Director of Technical Services, Pilkington Building Product North America

Learning Objectives: 1. Understand what thermal stress is and how it is caused. 2. Learn how poor edge strength of glass can lead to breakage. 3. Describe how shadows impact glass stress. 4. Define heat traps and how to avoid them. 5. How HVAC vents can cause glass breakage. 6. Appreciate the unique thermal conditions of spandrel glazing. 7. Understand solar absorption and how it affects glass temperature and stress. 8. Specifying glass and assigning responsibility for design and stress analysis. SUMMARY Window glass is heated and cooled by visible and invisible (infra red) radiation from the sun and other heat sources; by natural and forced convection from wind; by air from HVAC vents, etc.; and by conduction from contact with framing and other materials. The small differential expansions and contractions of the hot and cold areas create stresses which, if they are excessive, can cause breakage of ordinary annealed glass. STRESS The expansion of ordinary window glass with heat is small but can be of considerable consequence. For example, a piece of glass 50" x 100", when heated from 0 to 100°F, will only increase in size to 50.025" x 100.049". See: ATS #129 for thermal expansion coefficient, and Pilkington North America, Inc. "Good Glazing Techniques" brochure for proper glazing clearances, etc., to accommodate this expansion. When the glazed edge of a window light is shielded from sunlight by a frame, this covered edge will be cooler than the central area which is exposed, particularly on calm days when there is no cooling breeze. The expansion of the central warm area will be resisted by the cool edge. Typically, the hotter exposed area is much larger than the cooler edge area and so the edges are stretched into a state of tensile stress of about 50 psi (pounds per square inch) for every degree F difference between the center and the edge. On a calm day, sunlit heat-absorbing glass can easily reach 40°F above the ambient air temperature. The covered glass edge temperature will be somewhere between



that of the ambient air and the exposed glass. The frame detail determines how much heat reaches the edges; e.g., a deep concrete frame insulates the edges, while structural silicone glazing allows edge heating almost equal to that at the exposed area. In the example above with 40°F temperature difference, a stress of 40°F x 50 psi / °F or 2000 psi will be developed if the edge is fully insulated from direct solar heating. This stress value is approaching the strength limit for clean-cut, undamaged, annealed glass edges. EDGE STRENGTH When the tensile stress in a glass edge exceeds 2,000 to 3,000 psi, the probability of breakage becomes significant. The actual edge strength depends on the cut edge quality. The edges must be ‘clean cut’ (with minimum serration, hackle, etc.), fabricated (into insulating glass units, etc.) without damage from sealant nozzles, tools, hard surfaces, etc., and then handled and installed without being damaged to minimize the breakage probability. SHADOWS Shadows from vertical mullions and horizontal frame overhangs cause temperature differences in heat-absorbing glass. If a vertical mullion is less than 20" deep, then its shadow can be considered "mobile" as it sweeps across the glass because it does not remain still long enough to develop major temperature differences. Vertical mullions greater than 20" deep develop "static" shadows which develop higher glass stress. Overhangs greater than 3" deep develop static shadows. Mobile shadows typically develop 11% more stress than the "no shadow" situation. Static shadows develop about 35% more stress than the "no shadow" condition. Unusual shadow patterns, e.g. "V" or "L" shaped shadows, cause higher stresses than the simple cold edge case detailed above. It has been shown theoretically (Boley, 1964), and measured in practice, that the resulting stresses are not more than 30% greater than that for the basic condition of a hot central area with cold edges. HEAT TRAPS Heat Trap conditions caused by insulating blinds, drop ceilings below the level of the top of the glass, heat-absorbing labels or decorations on the glass, etc., can cause larger temperature differences than are allowable for annealed glass and may cause breakage.

Spandrel glazing represents the extreme heat trap condition where insulation, and restricted air flow on the room side, prevents the solar heat which has passed through the glass from entering the building. The only way for this heat, which is absorbed on the outer facing surface of the spandrel pan insulation, to leave the spandrel is by raising the glass temperature sufficiently for external convection and radiation from the outer glass surface to balance the heat input. Obviously such a condition can develop major temperature differences in the glass. Heat-strengthened (twice as strong as annealed glass) or tempered glass (four times stronger than annealed) is typically used in spandrels to prevent breakage from thermal stress, except in unusual conditions where the heat gain is ventilated to the exterior or there are no shadows or edge cover to develop large temperature differences. HVAC Heating, Ventilating and Air Conditioning vents which blow hot or cold air directly against glass will also cause excessive tensile edge stress for annealed glass, resulting in possible glass breakage. SPANDRELS Spandrel glazing is often used to cover the edge of a floor slab. Typically there is insulation between the glass and the floor edge. This effectively turns the spandrel into a solar collector with no exit for the solar heat gain other than back out through the front surface. Adding to the thermal load is the recommended use of double glazing in the spandrel to better visually match the appearance of the adjacent vision glass. In still air insulated glass, spandrel temperatures will easily exceed 100 ÂşC. To resist the resulting stresses fully tempered glass may be needed rather than heat strengthened glass. It can be noted that single glazed spandrels with polished edges have reportedly been used successfully in the past but it is suggested that those installations may not have had adequate insulation behind them, and the edge shadows from framing may have been minimal or non-existent.

The image above shows high stress fracture lines originating at the right hand side. In this spandrel glazing, the insulation behind annealed heat absorbing glass and shadows from an overhang and deep mullion caused excessive stress on a clean cut edge.

UNIQUE CONDITIONS Unique installations can cause potentially damaging temperature differences to occur. Some examples are given below: 1. Large horizontal sills in front of vertical or sloped heat absorbing glass where snow can accumulate. When the exposed portion of the glass absorbs sunlight a large temperature difference can easily develop between the exposed area and the portion of the glass shaded and cooled by the snow. 2. When sloped glazing meets a vertical wall a heat trap condition is easily generated at the interior by the rising hot air caused by sunlight, which has passed through the glass, when it is absorbed on the wall surface and then heats the air. Such a space needs to have a ventilation system to prevent the hot air from accumulating.

3. Inside corner reflections (where two curtain wall sections meet at a 90 degree angle, measured on the exterior, in plan view) cause increased temperature differences in glass when the heat from the glazing solar reflection of an adjacent glazing is added to the direct solar radiation.

(Continued on page 40)



(Continued from page 39)

SOLAR ABSORPTION The temperature reached by the exposed glass depends on its Solar Absorption. The absorption value is available from: brochures, LBNL Window 5 program, or the glass manufacturer. It can often be calculated from the relation: Solar Transmission (%) + Solar Reflection (%) + Solar Absorption (%) = 100 (%) Double glazing changes the amount of heat absorbed by each light depending on the inter-reflections between the two glasses. The effective absorption of the outer glass is typically increased over its nominal single glazed absorption value, while the effective absorption of the inner light is reduced from its single glazed value. These effective absorption values can be computed in the ‘Optical Data’ section of the LBNL Window 5 program. This slightly complex program is available at no charge from: http://windows.lbl.gov/software . The program does allow center of glass temperatures to be computed for any custom specified weather condition. The worst-case thermal stress typically occurs when the sun is shining directly onto the glass and the air is still. Unfortunately the program cannot estimate glass edge temperatures within the frame. It is the magnitude of this center-to-edge temperature difference that is the main factor in causing thermally induced stress and sometimes, breakage. The use of low emissivity coatings reduces radiant heat flow from the coated side. This increases the resulting glass temperature and stress. Triple glazed units have a unique condition where the absorbed heat in the middle light of glass faces insulating layers of still air on each side. The center light temperature can then rise significantly, depending on its absorption value. If a low emissivity coating is on the center light it both adds to the absorbed solar radiation and further inhibits the loss of heat from it. In general, a clear glass as the middle light of a sealed triple unit, with a low emissivity coating on either surface #3 or #4 (of the 6 possible surfaces), will need to be heat treated to prevent breakage from thermal stress. STRESS CALCULATION There are too many variables to give a simple table of when heat treatment may be needed to resist thermal stress for a particular installation. Steady state heat flow calculations can be made to approximate worst case situations, and some programs have been written using this process. A full analysis, with dynamically changing heat flow, using computational fluid dynamics for the air flow at the glass surfaces, plus a finite element analysis for glass stress, has not yet been written.



CONCLUSION Where glass temperature differences and the resulting thermal stresses are too great for ordinary (annealed) glass, then heatstrengthened or fully tempered glass can be used. High stresses caused by deep shadows, heat traps, insulating blinds, etc. can be accommodated by either heat strengthening or fully tempering the glass. Both products are generally strong enough to prevent breakage from typical thermal stresses encountered in buildings. Heat strengthening is generally preferred, where safety codes permit, because of the reduced risk of the spontaneous breakage which can occasionally be seen with tempered glass. Heat strengthened glass is also often preferable because it may have slightly less visible distortion than fully tempered glass. Full polishing of the cut edges reduces the weakening from cutting and handling damage. Polishing slightly raises annealed glass average strength, but not as much as heat strengthening. Annealed polished edges are occasionally used in marginal thermal stress situations. When specifying glass to resist applied loads and to meet solar, optical and thermal requirements, clear responsibility must be placed on who needs to show the design criteria have been met. The energy section of Building Codes typically specify solar and thermal criteria, and the glass type to meet the Code required applied load resistance can be determined with relevant ASTM standards such as E 1300 for "…Load Resistance of Glass…". But too often the suitability for a glass type in a particular installation is left as the responsibility of the glazing contractor bidding on a project. It need hardly be stated that thermal stress analysis is not typically the main skill of a glazing contractor. The person responsible for the glass design must accept or delegate the thermal stress analysis for their project. ASTM Standards group has developed a standard practice for determining thermal stress in single glazing (ASTM E 2431). It will be some time before their work is completed for thermal stress in double glazed units. Some major glass manufacturers have proprietary computer programs for thermal stress analysis for their registered customers, using their particular products. Pilkington Glass NA Inc. has a thermal stress analysis program, available to all, at no charge, on their website. As with all such programs, the user must take full responsibility that the program and its results are applicable to their particular project and its unique details.
