Department NewsPRI Selected for International Pavement StudyThe Department of Civil Engineering and the associated Pavement Research Institute have been named to the R21 Composite Pavement project team. The $4 million, two-year project aims to study composite pavements made up of both asphalt and concrete layers. The goal of the study is to de-termine performance characteristics, design procedures and construction guidelines for composite pavements. The principal investigator for the project is PRI Executive Director Mike Darter, with CE Prof. Lev Khazanovich serving as co-principal investigator. The Department of Civil Engineering and the Minnesota Department of Transportation (Mn/DOT) will be teaming up for a portion of the project. The R21 Project brings a total of just over $2 million in federal funds to the two partners and makes use of assets such as the Minnesota Road Research facility. PRI is excited for the project as it assures continued collaboration between the department and Mn/DOT in visible, important research in the field of pavement engineering. Other research institutions named to the project include the University of Pittsburgh, University of California at Davis and Applied Research Associates, Inc.

Rosene and Bonestroo Honored with Achievement Award Legendary CE graduates Otto Bonestroo and Robert Rosene were honored with the University’s Outstanding Achievement Award in recognition of their decades of professional and civic accomplishments. Bonestroo and Rosene have a long history of generously supporting the department, including funding building projects and scholarships. The pair received their ac-colades at a ceremony attended by peers, family and faculty during the department’s Fall Open House. Bonestroo (CivE ’49 and MS ’50) is widely lauded both for his business and engineering insight. In 1956, he joined with fellow award recipient Rosene and others to form the civil engineering firm Bonestroo, Rosene, Anderlik and Associates, Inc. (BRA). In the years following, Bonestroo became a leader in urban planning by serving terms on various guidance com-mittees such as the Minneapolis-St. Paul Area Metropolitan Planning Commission. Rosene too made a name for himself while working at BRA. In addition to co-founding one of the Midwest’s largest civil engineering firms, he specialized in the design of civic projects, government buildings and recreation areas like parks, ice arenas and swimming pools. In 1993, Rosene was named Engineer of the Year by the Minnesota Society of Professional Engineers.

C O N T E N T S

It is my pleasure to introduce myself as the new civilengineering department head, and to share with you some of the activities and accomplishments of our faculty, students and alumni in this edition of Civil Engineer. I have been fortunate to assume the head position at a time when the department’s teaching and research activities are arguably the best they have been in its nearly 100-year history. During my first year as head, I made it a priority to meet as many of the department’s alumni and friends as possible. I am absolutely convinced that this de-partment’s success could not have been achieved with-out the continuous and substantial support provided by its champions. It is with this in mind that I want to take this opportunity to thank the previous depart-ment head, John Gulliver, for fostering good relations with our alumni and the local community during his 10 year term. Sharing with you all of the good stuff that has happened over the recent months would require many more pages than is feasible. I hope you will enjoy the representative selections we made. In this issue, you’ll discover how our faculty and students are making in-credible contributions to both local and global society. Three stories concern the collapse of the I-35W Bridge and show how our faculty and students are discovering the engineering lessons to be learned from this tragic event. Another story shares how a dedicated group of students is making a difference by helping disadvan-taged communities around the world. And finally, we examine the legacy of former department head Prof. Charles Fairhurst and bring you up to speed on what he’s doing today. I look forward to meeting as many of you as I can in the future. Please feel free to stop by for a visit to experience firsthand the vibrancy in our classrooms and laboratories. In the meantime, please enjoy this issue of Civil Engineer.

the Heritage Gallery at the McNamara Alumni Center on Thursday evening, May 8, where they enjoyed a reception and buffet. The celebration continued the follow-ing day when department and campus tours allowed alumni the chance to explore the modern campus. A class pic-nic was held later at Northrup Memorial Auditorium where these alumni received caps and gowns for the commencement ceremony. The group then lead the Class of 2008 procession into Northrup, and later attended a post-commencement reception at the Campus Club Terrace, inside Coffman Memorial Union.

MTO Completes First Year of Operations

April 2008 marked the successful first year of operation for the Minnesota Transportation Observatory (MTO). This past year, the MTO has been in the spot-light on several occasions for its con-tinuing mission to be a hub for informa-tion and research on local and national transportation problems. Several new research projects where initiated during this past year total-ing in excess of $1.5 million. Most notable was the “Development of the Next Generation Metro-Wide simulation Models for the Twin Cities Metropolitan Area” project. This project aims to cre-ate a state-of-the-art hybrid simulation model for the entire Twin Cities met-ropolitan area. The MTO is also testing the “Transportable Low Cost Traffic Data Collection Device For Rapid Deployment For Intersections And Arterials” system. The MTO also began providing tech-nical assistance and project result dissemination for several “Access to Destination” projects headed by faculty across the University. Additionally, the MTO has hosted many visitors, includ-ing the University Central Corridor LRT advisory panel, the Hennepin County Emergency operations board, and the Denali National Park multidisciplinary research group.

6 Civil Engineer | Summer 2008

Civil Engineering junior Rachel Gaulke participated in the ultimate

extra-curricular activity when she was chosen to build a scale model of the former I-35W Bridge for the National Transportation Safety Board (NTSB). NTSB investigators hope the model will help them visualize why the bridge fell. The agency contracted with the University of Minnesota to produce the model because of its familiarity with the span. Civil Engineering Professor Carol Shield received the request from the NTSB and chose Gaulke for the project because of her steady hand and excite-ment for working on the project. “I immediately thought of Rachel because of her attention to detail,” said Shield. Gaulke, admittedly, was the perfect student for the intricate task. “I’m a perfectionist,” she explained. Gaulke crafted the 1/200th-scale, five-foot long model with model rail-roading plastic, and referenced bridge plans and photos for its design. The scale of the bridge was chosen to bal-ance fine detail with portability. The

bridge decks can be removed to offer a better view of the truss work. The trusses themselves are color-coded, with maroon highlighting compression members and yellow signifying tension members. Gaulke estimated she spent more than 150 hours over two months fabricating

the span. She built the model in her spare time between classes, work and studying. The high-profile nature of the bridge collapse meant the project had to be completed in secret. Gaulke kept her task hush-hush by working alone inside a nondescript office tucked into an obscure corner of the building. Constructing the model was not only a valuable way to contribute to the col-

lapse investigation, but also good prac-tice for the budding structural engineer. “The most important and useful thing I have learned in doing this project is time management,” Gaulke said. “I also learned the importance of precision and accuracy, and what can go wrong if measurements and calculations are not perfect.” While the model certainly required a lot of work, the student also found it enjoyable. “I usually work with concrete and steel, so it was fun to do something a little bit different,” said Gaulke. The model was shipped to Washington, D.C. where it will be used as a visual reference during NTSB brief-ings. After all the time and effort it took to make the model, do Gaulke and Shield want it back? “My understanding is they actually have a trophy case with lots of the models they’ve had built for their investigations, so we’re hopeful it’ll end up in there,” concluded Shield.

When the I-35W Bridge near the University campus in Minneapolis

collapsed it not only shook up driv-ers, but also local traffic patterns. In an instant, daily commuters were left scrambling to find alternatives to busy routes they’d driven for years. For traffic experts and professors Henry Liu and David Levinson the ensuing chaos of-fered a unique opportunity to study how drivers go about finding and settling on new routes.

Which Way To GoCommuters exercise as much personal preference in choosing the routes they take as the vehicles they drive. Their choices are often based on practical concerns like fastest speed, shortest travel time and roadway knowledge. But there are those who pick a path based on whimsical preferences too. “Some people drive along the Mississippi River because it’s more aesthetic, even though they’re only going 15 miles per hour,” said Levinson. Whatever the range of factors, there’s one attribute that all drivers appreci-ate and it’s the freedom to conveniently decide almost everything for themselves. “Travelers are generally self-selecting in terms of departure time, route and things like that,” said Liu. It’s the freedom of self-selection that also allows drivers to initially experi-ment with their routes. When a majority of people are thought to be driving their preferred route, traffic is considered to be in a state called “equilibrium.” “The idea is that in equilibrium there’s no way for you to improve your travel time because you are doing the best you could and everybody else is doing the best they can,” said Levinson. Traffic has never been scientifically observed to be

in equilibrium, yet it remains the theory underlying all traffic modeling. The problem is no one has ever had a chance to watch the condition develop. “The theory of equilibration is not well understood,” said Liu. “There’s no veri-fication in terms of the process.” Until now. The loss of the I-35W Bridge meant a popular and speedy route was gone, and along with it the surrounding area’s established traffic pattern. Liu and Levinson now had the perfect environ-ment to learn exactly how drivers choose their preferred routes and to see how equilibrium emerges.

Answering the QuestionsIn the early days after the collapse, Liu and Levinson teamed up with U of M cognitive psychologist Kathleen Harder to design a study to track how drivers adapt to the traffic disruption. For the first phase of the study, they handed out 900 copies of a questionnaire at bus stops and parking ramps in the Univer-sity and downtown areas. Drivers were asked to record daily information regard-ing departure time, arrival time, routing and the like. Two hundred of those forms were mailed back to the researchers. Liu, Levinson and Harder plan to keep track of the 200 commuters until after the new I-35W Bridge is finished to see how their driving habits continue to change and stabilize. But the research won’t just stop when the new bridge is opened. The project will continue to monitor the commut-ers. “We want to see if people return to the patterns they had before or whether they keep new patterns that they’ve learned as a product of this new disrup-tion,” said Levinson.- continued on page 14

Graduate student Alicia Forbes works on a structural computer model of the I-35W Bridge.

On a grassy Mississippi River flat NTSB investigators comb over the mangled

remains of the I-35W Bridge searching for the cause of its collapse. Finding the reason is a painstaking mystery with far more questions than clues. The Department of Civil Engineering is try-ing to find the answers first with a new student-run bridge study using com-puter models. “We’re trying to see if we can col-lapse the bridge on the computer,” said project advisor and Department Head Roberto Ballarini. “It’s a good project for students because it’s very exiting.” The team is using computer model-ing to determine if the combination of traffic, structural design and a suspi-cious gusset plate called “U10” were enough to bring the span down on Aug. 1, 2007. Doing so would precisely fin-ger the trigger for the structural chain reaction that sent the real bridge plum-meting into the Mississippi River near downtown Minneapolis. “It’s like a post-mortem; you’ll have the evidence to go along with the body,” said Ballarini. “We hope to learn as much as we can…and these lessons must be used and conveyed widely to reduce the likelihood of such a tragedy reoccurring in the future,” said co-advisor Taichiro Okazaki.

Team Players The dedicated and talented students working on the project are Charles Devore, Tor Oksnevad, Alicia Forbes and Minmao Liao. The unique project is advised by Ballarini, Okazaki, along with Professor Arturo Schultz and Professor Emeritus Ted Galambos. All four profes-sors are experts in their respective fields of steel structures mechanics, modeling, and analysis. The students are doing all the

research themselves, with the faculty providing only guiding oversight and advice. The researchers initiated the project almost immediately after the bridge

Factoring It All InAccurately modeling a complex struc-ture like the I-35W Bridge involves factoring in the bridge’s design, suspect components and the mix of stresses it was subject to at the time of collapse. This meant the team’s first step for was to learn as much about the bridge as they could. The students found informa-tion in bridge construction plans, NTSB reports and photographs. Even details like weather conditions and the loca-tions of vehicles and construction mate-rials piled on the bridge at the time of the event were gathered for incorpora-tion into the models. The next step in designing the mod-els was to plot a digital framework of the bridge based on its original design plans. It was an intricate task that required precisely translating two-dimensional drawings into 3-D space. The job was given to undergraduate - continued on page 15

dropped. “We went to the bridge site the day after the collapse,” said Ballarini. A short while later, the team secured a Small Grant for Exploratory Research (SGER) from the National Science Foundation. The federal agency supplied a SGER grant for a similar student-run research project following the California Northridge Earthquake in 1994.

In the rural Ghanaian village of Amponsah Akroase the water local

children drank often made them too sick to go to school. The water harbors the parasite responsible for Guinea Worm, a gruesome and painful disease. “You wouldn’t know if we came back in a year’s time if some of the kids would still be around,” lamented Jamie Velkoverh, a member of the U of M’s student chapter of Engineers Without Borders (EWB-UMN). Velkoverh and a water engineering team from EWB-UMN traveled to the village to fix the problem. The call to aid came from the Minnesota Christian Academy, a village school started by a Minneapolis teacher. The fact that the group answered the plea is a testament to both its expertise and compassion.

Bridging BordersEWB-UMN formed in 2005 and has 40 eager and active members committed to the organization’s mission. “Our goal is to partner with disadvantaged communi-ties around the world that lack safety, security, health, water supply, sanitation and energy to give them the necessi-ties to live a better life,” said chapter president Brian Bell. The group has got-ten off to a quick start working on their life changing projects despite being only three years old. “Our chapter has done projects in Guatemala, Ghana, and we’re currently working on others in Uganda and Haiti,” said Bell. For Bell and the EWB-UMN members, projects like the Ghana school offer both

a chance to improve their skills as well as the world. “It provides an amazing opportunity for students to get involved with these incredible projects that are changing thousands of people’s lives around the world,” said Bell. Unfortunately, the humanitarian construction projects also have another extraordinary value: cost. The upcoming Uganda project, without travel expenses, is expected to cost about $35,000. De-spite a raring willingness, the high price tag hinders the group’s ability to help as much as it would like. “We’re limited right now by money on how many proj-ects we can have and how many students can be involved,” added Bell. He says the only solution is reliable annual funding. With enough money, EWB-UMN mem-bers can continue to reach out and lend a helping hand, just like they did this past summer to the Minnesota Christian Academy in Ghana.

Gone to Ghana“The villagers just had a dirty stream down the road that they’d get their wa-ter from,” recalled Velkoverh. The roads near the Academy are unpaved and lined with open sewers. Any local water source likely holds Guinea Worm larvae, which grow to three feet long inside villager’s intestines, then emerge through a pain-ful blister in the skin. Velkoverh, along with fellow EWB members David Gasperino, Nathan Knutson, Per Hansen, Andrew Sander, -continued on page 12

Travis Kluthe and engineering mentor Walter Eshenaur travelled to Ghana on a two week mission to build a sanitary drinking water system for the village. Eshenaur, an employee of SRF Consulting, was chosen to advise on the project due to his professional engineer-ing experience and 13 years serving UNICEF in Africa. Sander found the motivation to help in the children he saw playing around him. “The kids hardly had any cloth-ing, shoes, and no toys. They took our Pringles chip can and played with it as a toy,” said Sander. The area is undeniably poor, but the Minnesota Christian Academy offers the promise of a richer life. It’s just a matter of keeping the kids healthy enough to stay in school.

Getting Down to ItEWB-UMN’s solution to the problem was to install a water distribution system consisting of eight 180-watt solar panels used to power a 300 volt submersible pump filling a 6,500 liter holding tank. The system was designed to be easy to

build, cheap to operate, self-sufficient, and above all, reliable. The very first day in the village the team set to work feeding pipes into a pre-drilled well. The top goal for the day was to at least get the water pumping. “We wanted to show we meant busi-ness,” said Sander. Much to the villag-ers delight, by the time the sun set the team had water flowing out of a pipe and into a steel drum. “Everyone from

make-do with what’s termed “in-country appropriate technology,” or in other words, locally available materials. Exotic components, like the solar panels and the water pump, were flown to Ghana as checked luggage, but basic building materials were bought near the village. Often, the homegrown parts weren’t exactly what the team had in mind. Components like pipes were found in in-consistent dimensions, but with a little ingenuity and adaptability the team made everything work. Most of the project’s materials were purchased from small specialty stores lining a nearby highway. Shopping trips for construction supplies usually took place each morning. Once items were found, paying for them proved to be an additional challenge. “There were no price tags,” said Sander. “You had to bargain to get a fair price,” added Velkoverh. The team arrived with all the tools and odd items it would need. The packing list included unique items like -- continued on page 14

the community was there and cheering,” recounted Velkoverh. Once the water was flowing, the next phase of the project was to erect a small-scale water tower and run distribution lines to the school and village. Build-ing the tower meant the team had to

Professor Emeritus Charles Fairhurst originally wanted to be a British air

force pilot. “When I took my medical exam, they said my vision wasn’t good enough to be a pilot,” recalled the dis-tinguished engineer. Fairhurst responded with a decision to go into mining. What followed was literally a ground break-ing career that would change the field of rock mechanics forever, and for the better. Following WWII, male high school graduates in Britain were required to serve two years in the military, agricul-tural or mining services. When Fairhurst failed the vision screening, his next choice was to serve his two years in underground mining. He quickly excelled in the discipline and was awarded a National Coal Board (NCB) fellowship to study mining engineering at Sheffield University. Fairhurst went on to earn a doctorate and a position with the NCB from 1948-1956.

Coming to America In 1956, Fairhurst moved to Minnesota to help solve a mining prob-lem on the Iron Range. “I was invited to the University of Minnesota because I had been doing research on rock drilling. It was a time when the taconite industry in Minnesota was having severe diffi-culty because the rock was very hard,” said Fairhurst. He quickly settled into teaching at the University. Before long, the then Head of the School of Mines and Metallurgy, Gene Pfleider, asked Fairhurst to develop the University’s first rock mechanics pro-gram. “I was actually teaching courses in other topics, but I said if you can find someone to take over those classes, I’ll develop the rock mechanics program,”

said Fairhurst. He set to work designing the curricula and opened the program to graduate students in 1959. As his work continued into the 1960’s and 70’s, Fairhurst found that he was dissatisfied with current practices in rock systems analysis. The problem was that the mechanics of large scale systems were far too complex to pre-

numerical modeling techniques for de-scribing rock systems. At that same time, the invention of computers provided the calculating power to quickly crunch numbers and make the numerical models a handy analytical tool. Still, the day hadn’t quite dawned on this new age in rock mechanics model-ing.

Itasca Emerges “It was clear that if rock mechanics was going to advance, then the research we were doing at the University had to be carried forward into field applica-tion,” said Fairhurst. Furthermore, the creation of the techniques also meant Fairhurst had an invaluable team of talented engineers that ideally should remain intact. “It seemed natural to try to develop a company that would allow them that opportunity and carry things forward into the field,” said Fairhurst.- continued on page 14

“a lot of Sharpies,” 1,000 zip ties, 200 feet of 8-guage wire, and something the local villagers couldn’t keep their hands off. “We brought a couple of cordless drills, which they had never seen before,” said Sander. Velkoverh remembered having a hard time keeping hold of her drill. “I’d be working on something and they would always want to take it away and use it themselves.”

Life LessonsAfter two weeks of hard work, the water tower was up and running. Initially, the pump filled the tank at a rate of 10 liters per minute, with expectations its performance would improve with adjust-ments. All the same, for the first time Amponsah Akroase had a safe, reliable source of water that would not only help nourish the bodies of its young students, but also help them keep their minds on school too. The EWB-UMN team, rather fittingly, learned many important lessons. As the group’s lone woman, Velkoverh saw how impressed the local girls were to see her working as an engineer alongside men. It made her quite popular. “The girls would come up to me and say, ‘I want you to be my friend.’ “ In turn, the girls taught Velkoverh a few important things themselves. “Personally, it was such a good experience to learn what life is like in these poorer countries and the impor-tance of water.” Sander echoed her sen-timent. “It opens your engineering mind to the problems that are out there.” The danger, of course, is that lessons such as these can be easily forgotten. For Sander and Velkoverh, the water well project only whets their appetites to learn more. Since serving in Ghana, Velkoverh has begun working on a project in Haiti to figure out a way to recycle plastic ration water bags into something usable, like sandals. As for Sander, he’s heading to Guatemala on another water supply project, this time for a town of 3,000 people. To him, working on EWB projects is the only way to live. “Once you’ve done it, you’ll keep doing it for the rest of your life.”

Path, from page 5

What’s more, sensors and cameras oper-ated by the Minnesota Department of Transportation near the bridge will give them additional data to make and con-firm their observations. In a novel new approach, the two re-searchers plan to examine the changes in bridge and surrounding traffic from the perspective of hysteresis. “The process is used in structural analysis, but it hasn’t been used in traffic before,” said Levin-son. In simple terms, hysteresis consid-ers whether or not a system springs back to its original shape or behavior after it’s been temporarily forced to change and how long it takes. The concept will have the researchers watching to see if drivers stick to their new routes when the bridge is reopened instead of resum-ing the old ones they used before the its failure. Once the overall study is complete, not only will it aid engineers dealing with other unexpected events, but also planned ones. “It will help agencies pri-oritize in terms their traffic management projects,” said Liu. With the new insight on equilibrium, traffic engineers will be able to arrange the order of construc-tion projects better so they produce less congestion, disruptions and headaches.

Fairhurst, from page 13

In 1981 Fairhurst decided the time had come to form a company, but his ascen-sion to Head of then Civil and Mineral Engineering left him too busy to do it alone. He was fortunate to find two col-leagues from industry, John Markham and Magnus Bergman, who were willing to accept the challenge with him. Aided by Cundall’s computer modeling develop-ments, Itasca Consulting Group broke ground in Minneapolis that year. Itasca took only three short years to take numerical rock modeling from the laboratory to the marketplace. In 1984, the company released its first commer-cially available modeling software called “UDEC.” Short for “Universal Distinct Element Code,” the software was de-signed for geotechnical analysis of soil, rock, and structural support in two dimensions. Following the release of UDEC, the

company added FLAC and other products to become a globally dominant player in mining, earth resource and civil geo-technical design projects. “The computer models Itasca has developed are probably the most generally applied for mining projects worldwide,” said Fairhurst.In the years since Itasca’s formation, the firm has grown from a handful of local researchers to more than 100 employees in offices around the world. A majority of the company’s consultants have ad-vanced education, with the bulk of them earning doctorates from the University of Minnesota. Fairhurst himself retired from the University in 1997 and now serves part-time as a senior consultant to Itasca.

Down Under “We’re trying to push the state of the art,” said Fairhurst. “Itasca, probably more than anybody else, is giving a bet-ter insight into how things are going to change as you push new frontiers.” Lead-ing the charge into new areas, Itasca’s engineers are digging deep into solving problems with petroleum harvesting, underground nuclear waste storage and carbon sequestration. Fairhurst and Itasca are also making new forays into scientific research. With a majority of the planet explored and rockets routinely flying into space, it would seem science has nowhere to go but up. Not to Fairhurst; he thinks sci-ence is on its way down. “Going below the surface is almost the last frontier,” said Fairhurst. “Around the world labo-ratories are increasingly going under-ground.” Scientists in maturing fields like particle physics and cosmology are keen to set up shop hundreds of feet under-ground where thick slabs of rock can shield sensitive experiments hunting for neutrinos and other elusive things. The National Science Foundation intends to build such a lab called DUSEL, short for “Deep Underground Science and Engineering Laboratory.” DUSEL will be constructed inside an underground mine and serve as a next generation lab for physics, biology, rock engineering, and other research. Fairhurst sees tremen-dous potential for DUSEL and believes Itasca has the expertise to help create it. Both literally and figuratively, Itasca has made a name for itself by digging deeply into understanding the nature

students DeVore and Oksnevad. “You have to calculate all the coordinates and it’s very tedious,” said Ballarini. By the end of September ‘07, DeVore and Oksnevad had the 3-D geometry plotted and ready for modeling, just in time for the arrival of Alicia Forbes.

Model Students “Sometimes I think it was just fate,” said Forbes. The new grad student had recently started her first year on-campus after graduating from Purdue University. She was anxious to work on a civil engineering failure analysis project. As luck would have it, Ballarini was Forbes’ new advisor. Their original plans were to study bone fracture together. “She hinted that she’d like to work on this project if an opportunity opened up,”

said Ballarini. Forbes’ verbal hand-rais-ing soon paid off. “Not too long after school started I was informed that I had the opportunity to work with the rest of the team to investigate the failure,” said Forbes. “I was excited and honored that I would get a chance to work on some-thing the whole nation was wondering about!” As Forbes puts it, her job was to know the bridge like the back of her hand and program the model to behave like the real thing. Whereas the undergraduate students merely gave the model shape, Forbes’ work gave the bridge model behavior by applying forces and loads to its digital makeup. Midway through the teams research the NTSB discovered the twisted U10 gusset plate within the bridge ruins. The gusset plate joined multiple bridge members and its failure may have caused the whole structure to unravel. Graduate student Minmao Liao has recently focused on taking a good look at the U10 plate design. He’s busy cre-ating a model to visualize the forces needed to tear it apart and see if it really is the key piece to the bridge col-lapse puzzle. When Liao’s gusset model is complete, it will be plugged into Forbes’ overall bridge simulation. Then the team will see whether it was the faulty U10 gus-

set or some other culprit that collapsed the bridge. The team is confident that in the next few months it’ll have answers to some or all of the major questions regarding why the bridge fell. Just as importantly, the select team of engineering students will also have unique expertise to help ensure it never happens again.

of Earth’s underworld. Fittingly, the company’s success has been guided by a man who views rock-hard obstacles as an opportunity to innovate and excel. Charles Fairhurst simply has a remark-able ability to see solutions, and that’s the sort of thing that can’t be predicted with a vision test.
