Ourachievements ranged from reorganizing thecommittee structure, streamlining theapplication process and working with thelegislature on a Good Samaritan Law, to holdingan organization meeting for a proposed FortWorth chapter. During the year, I attendedseveral conferences around the country andfound that there are many good people interestedin helping the structural engineering professionprogress. Next year I would like to continue tosee progress made in leadership activities forstructural engineers in local, state, and nationalcommittees; the inauguration of Fort Worth asour newest state chapter, and a strong attendanceat the NCSEAWinter Institute inAustin. It is saidthat if you lead, people will follow. One of thecelebrations at the NCSEA conference this yearwas to pay tribute to Jim Cagely, P.E. , whohelped found the organization fifteen years ago,contributing much in financial help andleadership. I see an opportunity for our membersat a local, state and national level to continue thistradition by attending meetings and participatingin committees. Sometimes this involves onlycommitting a few hours a year.Afew hours is notmuch, but it is this kind of grass roots effort thathas helped the organization grow into a vital partof structural engineering. Employers pleaseencourage your employees to volunteer in somecapacity on a local, state or national committee.Employees, please ask your employers if you canactively participate in the organization. Workingtogether, we can achieve lasting progress quicklyand accurately.We are working to increase our membership byreaching parts of Texas where there is an interestin SEAoT. Last January, the state boarddetermined that one way to do this was to addanother chapter.According to the Texas Board ofProfessional Engineers, there are over 220structural engineers in the Fort Worth area.Currently, 28 of these Fort Worth engineers aremembers of the North Central Texas Chapter(NCTX). However, distance and traffic canmake it difficult for them to participate in chapterevents. With Ft. Worth identified as a viablevenue for a new chapter, invitations to anorganization meeting were sent out to our NCTXchapter members as well as non memberengineers in the area. Some 30 engineersattended the meeting that was held at Freese andNichols offices in November. We are mostgrateful to John Dewar, P.E. for helping set thisup. We obtained the five signatures needed topetition the state board, and we expect thepetition to be approved at the next SEAoT stateboard meeting in January.SEAoT is honored to be the host state memberfor the next NCSEA Winter Institute that will beheld in Austin February 29 through March 1.(See page 6). One reason the program is comingto Austin is because past attendance has beenlight. SEAoT member Davy Beicker, P.E., whois NCSEA’s 2007 Treasurer, promoted Austinbased on the success of the half-day seminarshosted by our Austin Chapter. The two-dayNCSEA seminar will feature seismic design forthe 2006 IBC regions of low and moderateseismicity. The program includes a tour of theFerguson Structural Engineering Laboratory andthe NEES Equipment Site at the University ofTexas. The event will be held at the MarriottCourtyard Inn in downtown Austin. For hotelreservations call 866 816-8693, group code is#NCSNCSA. Register online for the Institutefor one or both days at Theseminars with be an economical way to obtainCEUs for Texas and other states such as NewYork and Florida because of the DiamondReview Program. Please consider attending andhelp to make the Winter Institute a success.In closing, I would like to thank the SEAoT stateboard members for their hard work and progress.Structural engineering is my passion and Iappreciate the opportunity to have beenSEAoT’s President in 2007. Next year, as PastPresident, I will chair the Activities Committeecoordinating the activities of the Hall of Honor,Awards and Recognition, Technical and Code,and Information and Technology committees.Please welcome Lee Walden, P.E. as the 2008SEAoT President and plan to attend the StateConference next October at Minute Maid Park.John SchwabSEAoT President - 2007Winter 2007

STRUCTURALENGINEERSTEXASASSOCIATIONTHE STRUCTURAL ENGINEERNCSEA REPORT 2007By Joseph J. Luke, P.E.In October, NCSEA held its Fifteenth Annual Conference inPhiladelphia. The delegates took the opportunity to look atNCSEA’s past and to honor past presidents. In 1992 there wereapproximately a dozen independent state structural engineeringassociations, including SEAOT, each representing its owngeographical area. A group of engineers from these associationsrealized that rapid changes to the profession and the complex needsof society for safe, sustainable and cost effective structures wouldrequire the profession to speak in a single voice. In 1993, NCSEAwas established to bring together the varied regional structuralengineers associations under the umbrella of a single organizationwhile still maintaining the independence and strengths of theseassociations.NCSEA continues to work on the goals outlined in the Five-YearPlan developed in 2005 and ratified at last year’s conference. Someof the accomplishments made last year in addressing those goalsinclude:Since NCSEA is already set up to do this, the effort onSEAoT’s part would be minimal.In addition to the above, NCSEA continues to work with ICC onIBC code issues relevant to structural engineers. Most recentlyNCSEAtook on the task of improving Chapter 17 of the Code.A good source of information regarding NCSEA is StructuresMagazine. This magazine is published jointly by NCSEA, SEI andCASE.As a SEAoT member you should be receiving this magazineas part of your membership. Besides very timely and informativearticles on structural engineering, there is a regular section onNCSEAactivities.During the Conference, SEAoT member Galen Schroeder receiveda DesignAward for theAustin City Hall Project on behalf of DatumEngineers. Congratulations to both Galen and Datum for theaward. This should serve as motivation for other structural firmsfrom Texas to submit their projects for the yearly awards.Here is one last little tidbit from the conference. The delegate fromthe Structural Engineers Association of South Carolina noted thatthere are some free structural design spreadsheets on its website.Go to and click on “Alex’s Corner”. Of course, alwayscheck software before using it.SEAoT representatives Joe Luke (left ) and Davy Beicker at theNCSEA meeting.Page 2Revamping the NCSEA Website, which continues to be agreat source of information on NCSEA activities.

THE STRUCTURAL ENGINEERSTRUCTURALENGINEERSASSOCIATIONSTRUCTURAL ENGINEERING & BIMTRAININGPart 1By Will F. Ikerd II, P.E., C.W.I.This article is part one of a series of article on Building InformationModeling training. This first article addresses some of the basicconcepts that structural firms should consider when planning onmoving forward into BIM.There are several main factors challenging our profession regardingBuilding Information Modeling adoption such as software andhardware limitations, litigation concerns, and economicconsiderations; however the most obvious and immediate challengefor a firm wanting to progress in BIM is training. Training is theprocess of teaching the right skills to the right set of people withminimal disruption. There is no secret course for the way a firm cannavigate these waters. The prominent factors include: firm size,background of staff, attitude of staff, and available time to learn,flight risk of newly trained BIM staff leaving for other firms. All ofthese factors need to be accounted for along with any additional onesthat might be specific to your firm. Generally speaking though, wecan gather several meaningful conclusions from consideringtraining in BIM. These are (1) first, we are training for a paradigmshift, (2) we hope to see a Return On Investment, and (3) finally, wehave little time to train in the fast paced economy inAEC.Training the Paradigm ShiftBIM training represents a paradigm shift that should include achange in design methods and work flow. The fundamental conceptto keep in mind is that BIM necessitates changes in staffing, workflow, project structure, and the way information is recorded.The BIM paradigm shift needs to be soberly addressed beforeimplementation because change is disruptive to current workflows.Knowledge and understanding of BIM as a method are paramountwhen faced with the natural corporate inertia that reacts againstchange. This concept of corporate inertia is obviously proportionalto firm size. Small firms under 10 people have little corporate inertiabut also have small economic revenue engines to power change.Large firms over 50 people have larger economic revenue enginesthat can allow a few focused staff to dedicate time to confronting thenatural resistance to change a larger group of people will have. It isthe midsized firms in between that have the large firm bureaucracyand resistance to change combined with lower revenue relative totheir size that makes a particular challenge to the paradigm shift.The RIO of the BIM ParadigmCommon wisdom is for firms to save some money by not investingin training in the hopes of learning the new technology while wework. I equate this to taking a very good truck driver who has beenhauling your clients load, handing him a jet plane manual and askinghim to go fly your client's cargo. At best, the truck driver will go tryto parallel park or backup the jet and then come back and tell you“This jet thing will never work!” and then go back to trucking.Another possibility will be that the truck driver actually gets it in theair with your client's cargo and then crashes and burns due to lack oftraining. Without training, those who know CAD will try to use BIMin the same way with very poor results at best, and possiblydisastrous client relation nightmares.The loss of billable hours for training is a very real concern, but itneeds to be viewed as an investment and not a cost. You shouldexpect a return on your investment and measure it as such buttraining is an investment. It seems from non-scientific polling offirms that three to six weeks of lost productivity per person can beexpected the first twelve to eighteen months of bringing a person online in BIM. In the following years they will gain back theproductivity loss during introductory period, and in the long termcontinue to capitalize and further build on that productivitythereafter. This long term return on investment is one of themotivations to change. However, as with any investment pastperformance does not guarantee future gains. If you pay on the highinitial cost of training and then let the staff be hired out from underyou, all of the hopes of return on your investment will walk away.Thus, staff retention will become an even more important factor inthis transition to BIM. The potential for ROI is very real as long asthe investments in staff are held on to maturity and not sold out tooearly.No time forAdvanced Training, Just-In-Time trainingNo formal instructor based training can replace the 'advancedtraining' that real project applications can offer after staff has hadbasic introductory training. Basic training would cover the softwareuser interface and more importantly recommended work flows.Ideally this would follow a path of having staff go through a threeday intensive basic introductory course in the application andimmediately follow into a real project with the same trainer involvedin consulting on setting up the first project and planning a strategyfor success as the project is under way. The consultant would also beavailable for quick phone conferences or meetings when the initialchallenges arise.Continued on page 17DOES YOUR WEB SITE DOJUSTICE TO YOUR PRACTICE?It is hard to sell professionalism if your web site looksamateurish, out-dated or incomplete.CALL US for a free, no obligation review of yourcurrent site and recommendations on transforming itinto your most effective marketing tool.SLizCALL FOR A FREE EVALUATIONSTANSFELD & FAIRBROTHERStansfeld at lizstansfeld@earthlink.net512 301 2744Page 5Page 5

STRUCTURALENGINEERSTEXASASSOCIATIONTHE STRUCTURAL ENGINEERHALL OF HONOR 2007 -PHIL MOSS FERGUSON: 1899 - 1986Each year, under the direction of Sam White, P.E. SEAoTresearches and recognizes Structural Engineers who have helpedshape the profession in Texas. In 2007, Professor Phil M. Fergusonof the University of Texas at Austin was nominated. Prof.Ferguson was truly a “pioneer” in the field of engineeringeducation andreinforced concreteresearch and design.Professor Phil M.Ferguson is recognizedas a leader indeveloping basictheory and designprocedures forreinforced concretestructures and anoutstanding civilengineering educator.He acted as Dean T. U.Taylor ProfessorEmeritus inEngineering at TheUniversity of Texas atAustin until hisretirement in 1976. Hisdistinguished scholarship and his leadership developing aninternationally recognized structural engineering program at UTwere recognized when the large structural engineering researchfacility at the University’s Balcones Research Center was namedthe “Phil M. Ferguson Structural Engineering Laboratory” in 1979.The son of a dentist, Phil Moss Ferguson was born in Bartlett,Texas, but moved to Waco when he was about seven. He graduatedhigh school in 1917. The following year, after a short spell workingfor the Gulf Refining Co., he rode the train toAustin and entered theCollege of Engineering. He received his Bachelor of Science inCivil Engineering in 1922 and a fifth year Civil Engineering degreein 1923. He received a Master of Science degree from Wisconsin in1924. He joined the Dwight P. Robinson Co. of New York as astructural engineer, where he was involved in design andconstruction of power plants, industrial buildings and high risestructures.In 1928, Ferguson accepted a job with Dean T. U. Taylor asAssociate Professor. For the next two decades he devoted hisenergies largely to the teaching programs at what was then apredominantly undergraduate institution. He was promoted toProfessor in 1939. He served as Chairman of the Civil EngineeringDepartment from 1943 to 1957, and played a leading role in theestablishment of the department's graduate engineering programs,supervising the first doctoral student in Civil Engineering at Texas.As Chairman, he recruited faculty members who becameinstrumental in developing what is now a world-class civilengineering program at Texas. While Chairman, he continued toteach supervise the growing number of graduate students.In contrast to many academic researchers, Phil Ferguson’s personalresearch and writing career did not bloom until he was past hisfiftieth birthday. In the late 1940’s Professor Ferguson wasintroduced to the world of destructive testing of reinforcedconcrete structural elements such as beams, slabs and columns. Hewent on to become one the nation's leading structural researchersmelding the behavior of structural elements with theory. Hispatience as a researcher looking for the truth in analyzing whymembers and systems failed enabled him to contribute much to thetechnology of reinforced concrete design.Following rigorous testing procedures he was conscious of theneed to load enough test specimens to failure to enable his students,himself, and his colleagues to be certain of their conclusions. Hewas a strong advocate for clarity in the writing of reports andpapers. His first serious, original paper at the national level waspublished on three-dimensional structural analysis in 1950. Thiswas followed by a number of papers exploring shear and diagonaltension in reinforced concrete which were recognized by theAmerican Concrete Institute's prestigious Wason Medals in 1954and 1958. His writings became internationally acclaimed and hehelped attract high caliber students to Austin while encouragingmany of the junior faculty to seek doctoral degrees. Many of thesestudents now hold leadership roles in structural engineering. Hisinternational stature as a leader in structural engineering researchand his development of design procedures led to election to theNational Academy of Engineering in 1973. His teaching abilitywas recognized by a General Dynamics Award for TeachingExcellence in 1962.In developing a research program in structural engineering whichwon wide acceptance and backing from government, industry,foundation, and trade associations, he provided leadership inpromptly translating research data into practice. His work led tomany of the significant breakthroughs in modern concreteresearch, especially associated to diagonal tension, torsion, slendercolumns, and reinforcement development.His renowned text on Reinforced Concrete Fundamentals was firstpublished by the American Concrete Institute. The papersubsequently went through several revisions. The Ferguson text isa digest of available research, design aids, and philosophy. Carefulinclusion of a balanced and unbiased evaluation of current designprocedures, comprehensive and forceful emphasis onfundamentals, and incessant urging that tradition give way to truthand logic justified his emphasis on ultimate strength procedures.The unusually wide acceptance of this work by the designer as wellas the teacher stands as a lasting testimonial. His research writingswere recognized three times by the American Concrete Institute’sWason Medal, a distinction accorded to only one other author in theInstitute’s history, and by the Raymond C. Reese StructuralAward.Continued on page 12Page 8


STRUCTURALENGINEERSTEXASASSOCIATIONTHE STRUCTURAL ENGINEER1A BRIEF HISTORY OF THE AASHTO BRIDGEDESIGN SPECIFICATIONSBy Linwood E Howell, P.E.AASHTO published the first nationally recognized compilation ofbridge specifications in 1931. Entitled Standard Specificationsfor Highway Bridges and Incidental Structures, the 240-pagepublication covered the essentials of bridge design andconstruction. The specifications had been compiled and revisedbeginning in 1921 with the formation of the Committee on Bridgesand Structures comprised of the Chief Bridge Engineer from eachState Highway Department.The First Edition included five Divisions that formed four distinctSpecifications. Division I, General Provisions, establishedprocedures for letting and administering bridge constructioncontracts. Division II, Materials, specified requirements for bridgeconstruction materials. Divisions III and IV, General Constructionand Special Construction, later combined into a single Division,specified construction methods and results. Division V, Design,consisted of 70 pages that comprised the first national BridgeDesign Specifications.The Early Effort to Innovate.The first national Bridge Design Specifications expressed a uniqueand innovative philosophy of structural design. The specificationcalled for two levels of allowable stress. A lower level at half thematerial strength was applied to Live Load and Wind Load. Ahigher level at three-fourths the material strength was applied toDead Load and certain secondary loads. This split-level designmethod foreshadowed modern probabilistic design philosophy thatattempts to achieve uniform levels of safety by adjusting factors ofsafety to reflect the variability of loads and materials.AReturn to Tradition.ndIn 1935 the 2 Edition was published under the shorter titleStandard Specifications for Highway Bridges. The original splitlevelallowable stress method, too radical and confusing to bewidely accepted among bridge engineers, was abandoned in favorof traditional methods known by various names such as workingstress design, allowable stress design, service load design, orallowable load design. These methods have in common a basicprocedure where the engineer attempts to specify materials of acertain type, quality, size, and configuration such that the strengthestimated for each structural component when reduced by a factorof safety will be at least as great as the estimated maximum loadsthe bridge will need to support.The Bridge Design Specifications codified standards forestimating loads and determining allowable stresses for commontypes of bridge components. Some effort went to specifyingengineering methods and formulas but few pages were required todo this since at the time the theory and practice of bridgeengineering remained relatively simple. The evolution of bridgedesign theory and practice since the 1st Edition has seen theoriginal 70 pages of the Bridge Design Specifications expand toover 2600 pages.By 1949 when the 5th Edition was published, the size had beenexpanded to 284 pages of which 89 pages comprised the BridgethDesign Specifications. In the 7 Edition (1957) the Divisions ofGeneral Provisions and Materials were removed to separatepublications. The two remaining Divisions of Design andConstruction totaled 290 pages of which 117 pages comprised theBridge Design Specifications.Updating the Design Philosophy.thThe 11 Edition, published in 1973, reflected a move within theengineering profession toward a probabilistic design philosophy.The initial step in this direction was the adoption of the Load FactorDesign (LFD) method presented in parallel with provisions for theolderAllowable Stress Design (ASD) method still favored by mostbridge engineers.In the LFD method, Dead Load, which could be estimated with ahigh level of certainty, received a 1.3 load factor whereas LiveLoad, which was difficult to predict or control, received a 2.2 loadfactor. Other load types received appropriate load factors.Subsequent editions of the specifications called for increasinglycomplex combinations of loads, load factors, and strengthreduction factors that tended to reflect committee consensus and adesire to achieve roughly equal design results whether using thenew LFD or the olderASD provisions.ATime for Reform.By the mid 1980's, bridge engineers generally acknowledged thatthe Bridge Design Specifications needed a major overhaul. Thespecifications were considered significantly out-of-date and notparticularly well organized and were seen to inadequately addresscertain important topics such as bridge railing, joints, bearings, andfoundations.In response to such concerns, AASHTO and the TransportationResearch Board commissioned a project to assess the BridgeDesign Specifications and recommend corrective actions. Theproject, completed in 1987, provided a clear picture of significantshortcomings along with a plan for rewriting the specifications tofully reflect the probabilistic design philosophy now widelyaccepted and known as load-and-resistance factor design (LRFD).While the LFD method had reflected probabilistic designphilosophy in a limited way, LRFD extends the concept to makeextensive use of statistical methods in assessing the variability ofloads and of the resistance provided by structural components.In 1988 AASHTO commissioned a follow up project to rewrite the2Bridge Design Specifications . The project involved thirteen taskgroups that drew heavily on current bridge research and designpractice throughout the world. The final draft was approved andpublished by the Subcommittee on Bridge and Structures in 1994under the titleAASHTO LRFD Bridge Design Specifications.A companion document entitled AASHTO LRFD BridgeConstruction Specifications was published in 1999 to completeupdating of both Divisions of the AASHTO StandardSpecifications for Highway Bridges.Continued on page 17Page 10


STRUCTURALENGINEERSTEXASASSOCIATIONTHE STRUCTURAL ENGINEERHall of Honor - Professor Phil FergusonContinued from page8No professional service gave Professor Ferguson more satisfactionthan his over 40 years of service as a member of the AmericanConcrete Institute Building Code Committee. He was an extremelyinfluential member of that committee which formulates the basicstandards for design and construction of reinforced concretestructures in the United States as well as many foreign countries.He served as president at the national or state levels of theAmerican Concrete Institute, the American Society of CivilEngineers, and the Texas Society of Professional Engineers. Hewas named an Honorary Member of both the American ConcreteInstitute and the American Society of Civil Engineers inrecognition of his long and distinguished service to those societies.Both The University of Texas and the University of Wisconsinrecognized him as a distinguished graduate.In 1976, Phil M. Ferguson was appointed Professor Emeritus atThe University of Texas, signaling the end of 48 years on the activefaculty. He continued to counsel the faculty and students and wasinvolved in professional and technical affairs, until moving toAustin near the near the end of his life. His final yearsimmediately before his death were spent in close contact with hissonYale, a professor of political science at Rutgers, his daughter inlaw and his grandchildren.In addition to his many technical contributions, Phil Ferguson willbe remembered for his spirit of uncompromising integrity, hisdedication to the application of fundamental engineeringprinciples, and his stimulation of young minds. A seemingly sternand demanding teacher, he inspired his students to strive forexcellence, but to never compromise their personal integrity orneglect their family and; civic responsibilities. Professor Fergusonalways devoted the last half hour of the last meeting of the semesterin his class on reinforced concrete (composed almost entirely ofsenior students) to presenting a personal challenge to the newengineers, asking them to be “truly professional” as CivilEngineers in the community following graduation. He made itclear that this professional responsibility to the public was moreimportant for them than understanding reinforced concrete theory.Phil Moss Ferguson was an unassuming, gentle man who leftbehind him a totally changed approach to teaching, research, andgraduate education in the two corners of his world which weredearest to him - his native Texas and the special world of reinforcedconcrete.(Source: Extracts from Phil Moss Ferguson’s Memorial Resolutionprepared by a special committee consisting of Professors John E.Breen (Chairman) Ned H. Burns, and J. Neils Thompson.)For more information on the Hall of Honor, see adjacent panelPage 12FUTURE OF THE SEAOT HALL OF HONORby Sam White, P.E.In 1908, the SEAoT Structural Engineering Hall of Honor will beaccepting nominations for outstanding engineers who began theircareers in Texas between 1900 and 1950. Thus, we will havecovered the first half of the twentieth century. By expanding thetime frame by ten years, 1940-1950, the Hall of Honor will nowmake eligible all of those who witnessed World War II and theimmediate post-war period.Although we have inducted five outstanding engineers from thishalf century period in to the Hall of Honor, there are many otherswho have not yet been recognized. The 1920’s was a boom time forconstruction, particularly in the downtown area of most cities. Eventhough most of this work halted in the early 1930’’s, the federalgovernment funded and otherwise encouraged many importantengineering projects during the depression. Of course, duringWWII construction work for the war effort greatly acceleratedacross Texas. Many military bases, production plants and defensefacilities were built during this time. Aviation-related projectsboomed in Texas during the war years and thereafter. Much of thiswe take for granted, but try to imagine what the state would be likewithout these structures.All members are encouraged to seek out older and retired membersof our profession to learn about the outstanding engineers of thistime in our history. It is never too late to document thecontributions of engineers of the past. Contact the SEAoT Hall ofHonor Committee member for your chapter and discuss your ideasfor honoring an important engineer from this time.All members areencouraged to participate in researching and documenting the livesand accomplishments of these individuals.The deadline for nominations will be 1August 2008.SEAoT Hall of Honor CommitteeRobert Tieman, P.E AustinGary ten Eyck, P.E North TexasBritt Gardener, P.E.

THE STRUCTURAL ENGINEERSTRUCTURALENGINEERSASSOCIATIONSTRUCTURAL ENGINEERING & BIM TRAININGContinued from page 5This process helps overcome the challenge of taking staff offproduction work for more than three days by leveraging just-in-timetraining to learn while working on real projects. Referring to ourprevious analogy, this option is like giving our truck driver realflight time training before letting him take off and then he is not'soloing'. He has a direct line to the same instructor that trained himwhen he soars into some turbulence.In summary, structural firms should consider the overall picture ofwhat changing to a BIM delivery method really means. This is adepth of understanding that acknowledges that this change is muchlarger than simply learning a new software, but rather a new workflow of the way we do our business. Secondly, they should view theROI in a holistic why that considers staff retention. Finally, thetraining must be a mix of both pure training and just-in-time on thejob training with support on the first few projects. The next article inthis series will focus on the various forms of pure training availableand the advantages and disadvantages of each relative to firm sizeand staff profile.

In 2002 the 17and final Edition was published to incorporate interim updates.These updates were limited to technical corrections since allefforts of substantive updating had focused on the LRFD BridgeDesign Specifications.The Future of Bridge Design.With the 2007 publication of the AASHTO LRFD Bridge DesignthSpecifications,4 Edition, bridge engineers have an invaluabletool for designing bridges of the future with superior serviceabilityand uniform levels of safety. This remarkable book is the result ofa five-year research effort and the continued efforts of theAASHTO technical committees to incorporate the results of thelatest research and the expertise of the bridge engineeringcommunity.1.The American Association of State and Highway Transportation Officials (AASHTO) is astandards writing body with quasi governmental powers that was originally incorporated in1914 under the name American Association of State Highway Officials (AASHO). It wasreorganized and reincorporated under its present name in 1984. Since its inceptionAASHTO has served as the primary national authority on highway design standards andtesting procedures for highway construction materials.2.“Development of Comprehensive Bridge Specifications and Commentary”, TransportationResearch Board, NCHRP Project 12-33, Modjeski and Masters, Inc., 1993.Page 17

THE STRUCTURAL ENGINEERSTRUCTURALENGINEERSASSOCIATIONBIG DIG TUNNEL CEILING COLLAPSE - ADIFFERENT VIEWPOINTTo the editor:The article on the Big Dig Tunnel Ceiling Collapse (NationalTransport Safety Board report reprinted in The Structural Engineer,Fall 2007) blames the ceiling collapse of Interstate 90 connectortunnel in Boston on the inappropriate use of epoxy anchor adhesiveand “creep.” It is my opinion, based on a great deal of professionalexperience, that many of the findings of this report should beseriously questioned. I would like to suggest that the followingpossible, but very simple causes also be considered:1. Wrong drill size. Epoxy grouts are very sensitive to ‘creep’problems when an oversized bit is used to drill holes. Even avery small over-specification of the drill bit, perhaps as littleas 1/4” can cause serious bonding and creep problems.2. Wrong drilling angle. It is not uncommon for the driller toturn the drill body round and round while drilling in order toease his up-push effort, particularly if the drill bit is dull orhad a wrong point bevel. The result is a cone-shaped hole,with the large end at the surface, making ‘creep’ problemsworse!3. Wrong drill depth. This is a common field problem. If thedrilled hole is too deep, the inserted bolt will push the epoxyahead, up into empty space, instead of through trappedepoxy that would force it to flow back downwards andaround the bolt as intended.All three of the above scenarios can be prevented if a knowledgeableinspector is present during the drilling process.4. Wrong epoxy mix: It appears that in the Big Dig Tunnel, theepoxy mix specifications were for holes drilled down, whenin fact these holes were drilled up. To avoid this, the epoxymix should be specified by someone knowledgeable inepoxy bolting work, rather than boilerplate specificationwork.5. No depth gage inspection of hole filling (or, the lack offilling) during the epoxy fill work. If nothing else isavailable, a simple stick can work as depth gage.6. No testing of installation technique before starting work onthe up-drilled holes. The National Transport Safety BoardReport never mentions anything about testing of fill, of mix,of drill, of set time, of cure method, of pullout strength gainper cure time, or of install temperatures. All are critical tosafe embed tension anchorage with epoxies.7. There is no mention in the report of vibratory loading on roofpanels and anchors. Any person who has ever worked in atunnel roof over traffic will attest to this one: Trucks passingbelow exert a windblast uplift as they pass. The force flapspanels hard as every truck goes by. Even cars give someupforce. As a result, anchors are alternately relaxed andover-pulled (by reactive flutter down-force, panel weightinertia) by every passing vehicle. With thousands passingvehicles, the vertical flutter motions per anchor becomessignificant. None of the publications I have reviewed on thesubject of these tunnels discusses how much overload (intension) is/was caused by this flutter, compared to deadweight of the panels.7. It would be interesting to know what cure temperature ordampness of hole was specified in matching the grout mix tothe job. I find most specifications do not regard theseconsiderations as important, when in fact they are critical!The report concentrates on ‘creep’ of bolts out of holes. However,this is a known issue with every epoxy bolt installations. Was thereport giving this so much emphasis in order to gloss over otherdeficiencies? PerhapsThe lack of proper specification.The lack of proper field inspectionAT EVERYBOLT.The lack of proper worker training.The fact that there are many grouts which will work well inthe manner needed on this job, but were not specified by thedesigners.There is also a real-life fact that is often not overlooked thedifficulty of drilling upwards. The driller must contend with theweight of the drill, the drag of the hose or wire, the constant showerof dust falling onto his face and possibly interfering with his vision,the up-force needed to penetrate strong concrete, and the stamina tokeep “correctly” drilling hole after hole. And, many of these jobsinvolve thousands of holes.So, how should this tough problem be addressed? Three possiblesolutions come to mind:1. Specify cement-grouted anchors, in oversize air-drilledholes, with center-bolt-hole filling for 100% surety in totalbolt surrounding by the grout. Grout, which is insensitive tolow concrete temperatures was present in those tunnels.However, Boston tunnel outer walls often remain at around40-50 degrees F. year round. This temperature is hardlyconducive to good curing for epoxies, and is not much betterfor cements. However, the right mix can perform correctly inthis temperature range.2. Eliminate all drilling. Set the anchors as the wet tunnelconcrete is poured. With today's drafting and field layouttools, accurate placement often cited as a reason againstthis approach should not be an issue. I have used thistechnique myself many times as have many others!3. Set anchor plates in the wet concrete, and simply weld tothese when the exact anchorage spot is known. I have alsosuccessfully used this technique.Ramon J. Cook, P.
