Leslie  Earl ROBERTSON  ( 12 th Feb 1928 - 11 Feb 2021 )
( Continued from previous post)

ROBERTSON  , the American  Structural engineer  was highly innovative and a self made  expert since he never liked interference in his design work.
Even when he was entrusted design of Twin Towers,  he declined to consult other senior experts of that time.

His innovative works were - First use of Space frame Mega structure & outrigger for High Rise ; First use of multi-columns and Spanderal Wall panels to allow column free  interior spaces and to resist lateral forces generated by hurricane  winds ;  Creation  of Mechanical damping units  to reduce sway in Tall buildings due to heavy winds.

List of projects dealt by him is long , to name few - Twin Towers of WTC at NY City ,  US Steel Tower in Pittsburgh  , Bank of China Tower in Hong Kong  , Madrid's Puerta de Europa Tower .

He received many awards and recognitionS.

ROBERTSON died of blood cancer last year , one day before his 93rd Birthday, but Structures of Earl  Robertson STAND TALL.

JOSEPH BAERMANN  STRAUSS ( 1870 - 1938)

Born in Cincinnati  Ohio US , Strauss was American Structural engineer who revolutionized  design of Bascule Bridges. He was Chief  Engineer  of famous Golden GATE  Bridge which was longest span Suspension Bridge  at that time.

Baermann was born in artistic family , mother a  Concert Pianist and father was a Writer and Painter.   During his college days , he fell sick and hospitalized where   his hospital room overlooked a suspension  Bridge.  This sparked great interest in Bridges leading him to seek a Civil engineering  degree  from University of  Cincinnati in 1892.

Being a structural Civil engineer , his interest  in poetry never died and he wrote  famous poetry " MIGHTY TASK IS DONE " after completion of  Golden GATE Bridge . He also penned popular poems - REDWOOD  ;  SEQUOLA.

Strauss was highly safety conscious  for all personnels/ workers working at GG Suspension Bridge and a movable  safety net was provided under deck during construction which resulted in saving about 19 lives.

JOSEPH BAERMANN STRAUSS ( 1870 -1938 )
( continued from previous post)

Strauss , after seeking CE degree in 1892 ,  joined Bridge Consultancy firm Ralph Modjar and gave innovating ideas to reduce cost . He proposed Concrete counter weight instead of steel in Bascule Bridges. Sometimes his new ideas were not given weightage  and he decided to open own Bridge Design firm.

Golden GATE Suspension Bridge having length of 2.7 km , has 1.6 km span with 227.4 m height is 6 lane Bridge  connecting San Francisco to Marin County , bridging through golden strait .

Joseph Strauss was consulted for construction of GG Bridge,  which was felt to be impossible due to 2 km strait , strong swirling tides , water as deep as 115m . His reputation of design & construction  of  89 km rail road across Barring strait was a ray of hope to the Authorities.  Strauss agreed to work as Chief Engineer  for Golden GATE  Suspension Bridge  project.

JOSEPH BAERMANN STRAUSS ( 1870 - 1938)
(Continued from previous post)

Golden GATE Bridge Authorities Estimated the cost as 100$ million  and funds were not there.  Srauss  , the appointed CE ,  proposed the design of Golden  GATE Bridge  with massive  Cantilever at each end with a central suspended  span and costing only  $17 million.

But there was stiff opposition for this Bridge  from Deptt of  War stating that Bridge would interfere  with ship movements . US Navy feared collusion or sabotage causing blockage of movements  to main harbors. Further South Pacific Rail road Authority  strongly opposed new route  , but Joseph Strauss  was a man of strong determination . Even though his original design was changed due to aesthetc reasons , he continued to work on the project facing problems on every front.

Strauss arranged funds from Citizens , and US Military convincing them of advantages of project. Automobile Industry also supported Strauss. The Bridge construction started in 1933 , got completed in 1937 at a cost of $35 million.

After completion of  GG Bridge  , Strauss penned his poem "Mighty Task is Done" . But he died one year after opening of GG Bridge at Loss Angeles,  California US  and rested at Forest Lawn Memorial Park.

WILLIAM  FRAZIER  BAKER ( 1953 - STILL ACTIVE )
( The Structural engineer  of Burj Khalifa)

Born in Fulton Missouri , US  and grown up in small town of  Midwest having a population of 10000 people and Tallest buildings only two storieyed , William Baker , also known as Bill Baker , was destined to design Tallest Building of World Burj Khalifa as Structural Designer  of the super tall mega project .

Bill Baker while in high School was tested for his aptitude and it was revealed  that he would better persue engineering.  His Grandfather and great GF were Structural engineers of their times,  though not alive , the inheritance in  Bill was imminent when he aspired for Civil Engineering over Architecture.

William Baker completed his BSc Civil Engg degree in 1975 from University of  Missouri,  worked in Exxn Mobil for some time and persued  MSC Structures from University of  Illinois, completing in 1980.

Bill Baker was appointed by leading Consulting Firm Skidmore ,  Owing &  Merrill (SOM) in 1981 as Structural  Engineer , and in 1996 he was made Partner . This firm has expertise in Tall Buildings , Chief Architect is Adrian  Smith. BILL'S  expertise  on Super Tall Structures was instrumental  in  winning prestigious BURJ DUBAI prestigious project.

WILLIAM FRAZIER BAKER (1953 - STILL ACTIVE)

Bill Baker  in an interview  said  that he enjoyed designing even  single storeyed small homes  which shows his scale of working from one storied buildings to Tallest man-made Structure  on earth ,the BURJ KHALIFA  BUILDING.

Burj K is 829.8m high  (about  2.5 times ht of Effiel tower )  having having a floor space of 334000 sqm ( twice the floor space of China's Forbidden City). For design and construction of such sky high building  Structural design was greatest challenge within the limits of aesthetics  and constructability. Many projects of even much lesser heights were not taken off due to problems posed by Construction  .

In interview , Bill Baker revealed that Burj Khalifa building surpassed Tallest Building Taipei 101 by height with margin of 60% , contrary to height increase trend,  where Tall  buildings from  Empire State  to Taipei 101 , were higher by narrow height margins.

Bill Baker 's Two decades  experience  on Tall Buildings , especially Tower Palace Three in South Korea with Three wings having same geometry as Burj K ,but adopting different  structural system proved  handy.

WILLIAM FRAZIER BAKER (1953 - STILL ACTIVE)
(Continued from previous post)

Bill Baker 's  aptitude in Structural analysis   and his untiring efforts in diping / reducing  aerodynamic forces  by rotating building and fine tuning the building Geometry,  testing in Wind tunnel and simultaneously  satisfying the Architect's functional and aesthetic requirements was key factor in success of this mega project.  He accepted challenging and demanding requirements to design a sky tall building ensuring constructability.

Baker's  experience on  Tower Palace building   was  that  even with small changes in building Geometry ,  dramatic increase or decrease  of forces take place and therefore Burj K was not going to be  any exception. He also stuck to stay in module to have rigrous grid to the building avoiding transfers . Burj K was tested with various rotations and rotation at 60 degrees  resulted in minimal aerodynamics  as  per Bill Baker.

The system of structure proposed by Bill for this super Tall  building was 'Butteressed Core Structural  System". Baker used mostly rcc and Structural steel was less with building . Grounding steel was stainless steel embedded in surface concrete for lightning protection. Baker advised ice cooled concreting  in hot temperatures and Construction  firm M/s Samsung Constructions  carried the entire construction.

WILLIAM FRAZIER BAKER ( 1953 - STILL ACTIVE )

Skidmore Owing & Merrill (SOM)  headed by Chief Architect Adrian Smith  and Structural expert partner Willam Baker  alongwith Company' s Urban Planners , Interior Designers , Sustainability  Engineers and other professionals , all  worked tirelessly  with Baker at centerstage .

Bill (William)  Baker , in an interview,  also acknowledged  the expertise and efforts of Construction firm Samsung Constructions  in timely and successful completion  of mega Project of BURJ KHALIFA , on which Emaar Properties,  the Owner,  gained alarming profits as entire spaces were sold out at start of project. The vicinity areas rates have gone many times due to Burj effect as revealed by Baker .

Baker strongly  believed/believes  that time is greatest enemy if it overruns  in any project since ,  longer it stretches  , more things can happen   , political changes may affect project  , economics affecting cost ,  critical personnel falling sick and not available etc.

Baker 's other Tall Building projects are - Tower Palace Three  In South Korea ( already discussed in previous post) , Trump International Hotel & Tower , Cayan Tower and many more.

William Baker received many awards and recognitions . He is Fellow , ASCE ;  IASTRUCTE  and member National  Academy  of Engg.  

Being Structural designer of World's Tallest Building / Man made structure , his name is already in  HIGH  SKIES   as Living Legend of  Structural engineering .
