FOREWORDOver the course of 100 years, change is constant. Ideas and ideologies, texts and tastes are unilaterally revised. History is re-written. Along the undeterred path of progress, the most lasting remainders of par-ticular moments in time are those that stand concrete and indisputable. Buildings are the artifacts by which we may judge the past. Each structure stands for the intentions and ideals of its design, and the hard work and ingenuity of the builder that brought it to fruition. Because of the builder’s craftsmanship and care, many structures remain long after those intentions and ideals either merge and strengthen, or falter and give way. In essence, every completed structure stands as a monument to an idea made tangible through expertise during a moment in time.

Irwin & Leighton has been, for 100 years, deeply entwined in the changing intentions and ideals of our culture. As a trusted builder, Irwin & Leighton has consistently partnered with leaders and pioneers in facilitating innovation in an array of fi elds. Railway stations and telephone exchanges connected the American public. Summer resorts and theaters have entertained, while federal banks, courthouses, post offi ces and army encampments have provided the comforts and securities of a modern infrastructure. Factories produced products that changed lifestyles. Modern retail stores re-energized consumerism, while great educational and research facilities unleashed world changing ideas _ all under the roofs of buildings Irwin & Leighton constructed.

Irwin & Leighton takes pride in its involvement with the great wave of technological and cultural innova-tions over a century, and its part in achieving these advancements. Herein are examined a selection of many pioneering projects Irwin & Leighton is proud to have partnered in since its founding in 1909.

INTRODUCTION

2009 PRESS ROOM EXPANSION UNDER CONSTRUCTION, READING EAGLE COMPANY

Reading, Pennsylvania • Architect: Muhlenberg Greene Architects

What follows is the story of Irwin & Leighton and its fi rst one hundred years in business. It is a story of strong management, expertise, perseverance, and good fortune. Above all, it is a story about an enduring mutual loyalty between a company, its customers and its employees alike, and the great achievements that have come from it.

Irwin & Leighton’s customers have consistently been the leaders and innovators of the age, giving us the privilege to have been a part of the history and growth of our great country. Furthermore, Irwin & Leighton’s great stability is evidenced in the fact that in over one hundred years, the company has had only four leaders and four headquarters locations. Customer relationships are measured in decades. Talented, hardworking and sincere people have devoted signifi cant portions of their careers in the employ of the company and continue to do so. This wonderful synergy of quality customers, stable competent leadership and outstanding staff has forged a unique organization that has been a continuing source of pride to its employees for one hundred years.

ii / OUR FIRST ONE HUNDRED YEARS

This book represents a collaborative effort to chronicle Irwin & Leighton’s great journey since 1909, and will demonstrate how worldwide events, emerging technology and economic cycles directly infl uenced Irwin & Leighton’s growth and its “hand in history.” Through this book, today’s Irwin & Leighton employees will gain more knowledge about the roots of their organization and the foundation of achieve-ment upon which they stand today.

At the celebration of its 100th anniversary, Irwin & Leighton is a healthy and vibrant organization because it has consistently adapted to the changes of its time, made key decisions with a long term conservative view and developed and retained great customers and great employees. In so doing, this remarkable organization has remained a leader in its fi eld for all these years. Our challenge for the future is to continue on the same path.

This tribute to Irwin & Leighton is dedicated to its employees, past and present. It is for all those who have proudly stood the “long green line” during the last one hundred years and simply done their jobs well.

It is for those who poured the Hotel Strand foundations with mules in 1909, and who framed the Camp Dix Barracks in sixty days in 1917. It is for those who successfully planned the extensive work at Bancroft Hall in 1939 and who persevered through the Ithaca winter to build Cornell’s Synchrotron Lab in 1966. It is for those who diligently placed the massive Telephone Exchange Building caissons in 1970 and for those who refused to yield to overwhelming adversity in order to complete Princeton’s Scully Hall on time in 1998.

This tribute is especially dedicated to the employees of 2009, who come to work every day eager to lend their skill, ingenuity and spirit to a company that brings out the best in all of us.

Extraordinary efforts are common at Irwin & Leighton. Lights burn late to be ready for the next day’s bid, or to issue an invoice on time. Sleep is lost pondering the correct purchasing decision or a pressing schedul-ing issue. The appearance and accuracy of administrative work is, by rule, taken very seriously. Because of the personal dedication and expertise that drives such everyday efforts, Irwin and Leighton is the outstand-ing company it is today. Your efforts are most appreciated.

This, then, is for you.

2000 IRWIN & LEIGHTON’S CORPORATE HEADQUARTERSKing of Prussia, Pennsylvania

A Brief History Of Our Company

1909-1955

In 1909, Irwin & Leighton was founded through the partnership of A.D. Irwin and A.O. Leighton. Cor-porate headquarters were initially located at 126 North Twelfth Street in Philadelphia. Mr. Irwin, a native Philadelphian of means, acted as the primary investor and business manager, while Mr. Leighton managed the completion of projects and the direction of personnel.

Benefi ting from early connections and ingenuity, the young company was able to distinguish itself quickly. From the beginning, strong customer relation-ships were forged that would prove to be central to future prosperity. Lead customers of the period included the Pennsylvania Railroad, Bell Telephone, Sears, Roebuck and Company, and Ford Motor Company. The company also did major work for the U.S. Government, including the Cantonment at Fort Dix which was built under an aggressive schedule in order to support the quickly expanding needs of the military at the onset of World War I.

A reputation for dependable performance was born.

After World War I, modernizations in healthcare and technology fueled company contracts to build steel mills, telephone buildings, modern hospitals, and prominent offi ce and educational facilities. The company built for organizations that became central to the growth of the Philadelphia area such as the Victor Talking Machine Company, Campbell Soup, Philadelphia Electric, Atwater Kent Manufacturing and Strawbridge & Clothier.

In 1927, the Philadelphia headquarters moved to 1505 Race Street, where it re-mained for nearly fi fty years.

The Depression Era brought about hard times for most Americans and their busi-nesses. Irwin & Leighton’s corporate re-cords indicate that in the ten years from 1930 to 1939, only 54 projects were com-pleted, refl ecting greatly reduced activity for the company. Nevertheless, Irwin & Leighton persevered and survived.

1909 1920

Activities of the 1930s included the construction of numerous hospitals for the Gen-eral Services Administration (GSA), the sprawling Cantonment at the Aberdeen Proving Grounds, and several prominent projects at The United States Naval Acad-emy in Annapolis _ including the renowned Bancroft Hall which, to this day, is the largest single dormitory in the world.

During World War II, the company worked for Bethlehem Steel and other industrial companies involved with the war effort, including Sharpe & Dohme, Westinghouse Electric, Owens Illinois Glass, Container Corporation of America, and Armstrong Cork Company. However, and true to form, throughout the 1940s, Irwin & Leigh-ton’s most active customers were its oldest. The company built three projects for RCA, four for Ford Motor Company, and nine stores for Sears, Roebuck and Company.

The post-war period saw Irwin & Leighton become heavily involved with projects surrounding the growing economy of the late 1940s and early 1950s _ building schools, hospitals, manufacturing facilities and suburban retail stores.

After the war, a young William O. Olmstead joined Irwin & Leighton. Bill, a graduate of Thayer School of Engineering at Dartmouth, served in the South Pacifi c during World War II and as the Naval Offi cer in Charge at Willow Grove Naval Air Force Base where he came to know Irwin & Leighton. Bill would become the future head of the company.

1955-1978

The importance of the Founders’ actions in 1955 cannot be overstated. In that year, after nearly fi fty years of successful business, Messrs. Irwin & Leighton made an important decision that dictated the future of their company. They could have simply dissolved the organization, but instead, solely in the interest of their employees, they took the steps necessary to allow the company to continue without them. By selling the company to its employees, they allowed the creation of a unique construction organization held by key employee stockholders and free of family infl uence. Irwin & Leighton, Inc. was born.

The process of incorporation was completed with the guidance of attorney Paul I. Guest of Guest & Greene. Paul, a bomber pilot in the U.S. Army Air Force during World War II and a graduate of Ursinus College and the University of Pennsylvania Law School, became involved with the fi rm, we believe, in the early 1950s. He was counsel during all four eras of leadership at Irwin & Leighton, guided the fi rm through each of three successful management transitions and, to this day, has been the only non-employee stock-holder in the company.

A BRIEF HISTORY OF OUR COMPANY / vii

1940s1930s1930 1940

Staunchly loyal to and supportive of Irwin & Leighton, and an avid golfer until his death in 1986, Paul is honored and remembered every year when the company holds its annual Paul I. Guest Memorial Golf Tournament.

With incorporation in 1955, Bill Olmstead was named President; he proved an effective, easy-going leader, popular with employees and clients alike. Bill would be central to shaping the unique culture of employee ownership and tradition of conservative leadership by consen-sus that have been fundamental to Irwin & Leighton’s stability and success. For these reasons alone, his legacy will endure at Irwin & Leighton.

The “Baby Boom” motivated expansion in retail, educational, communication, transportation and healthcare facilities in the 1950s, and Irwin & Leighton continued to provide quality service during this period. The company built such Philadelphia area retail landmarks as the Wynnewood Shopping Center and completed major projects for Episcopal Hospital, Jeffer-son Hospital and The Hospital of the University of Pennsylvania.

Similar to the early years of the company, strong customer relationships were fostered in the 1950s that proved to be signifi cant to future success. Irwin & Leighton earned new business with John Wanamaker (1953), Lafayette College (1954), Princeton University (1955), Ursinus College (1956), and Cornell Uni-versity (1957).

To this day, Lafayette College and Princeton University remain among the company’s most vital and im-portant customers. In a 55-year relationship with Lafayette the company has completed ten major projects in addition to numerous other smaller contracts on Lafayette’s Easton campus. This record includes the award winning Farinon Student Center. Irwin & Leighton has undertaken 50 projects for Princeton Uni-versity during a 54-year relationship; these projects include the acclaimed Jadwin and Fine Halls, Scully Hall, Little Hall, Witherspoon Hall and Madison Hall projects.

Mr. Leighton continued to report to work at 1505 Race Street through the early 1960s. According to employees, he spent mornings playing his beloved violin at home in Villanova before arriving to the offi ce around lunch time. Known for his wit, he would chide employees about their diet and health and often recite humorous (and sometimes unprintable) limericks.

Mr. Irwin also visited the offi ce, though more sporadically. He was not likely to participate in the lighter engagements of his partner, Mr. Leighton. His presence commanded respect and seriousness and he was known for his insight and wisdom.

Mr. Irwin and Mr. Leighton both died in 1964.

1950s 1960s

MR. LEIGHTON

19601950

In the 1960s, the fi rm earned the business of leaders such as Philadelphia Gear, Smith Kline & French, Armstrong Cork and Air Products. Other customer relationships started in this decade with McGraw-Hill, Children’s Hospital of Philadelphia, AT&T, Educational Testing Service and Mobil Oil would endure for thirty years or more. Irwin & Leighton also was prominently involved in the construction of suburban retail stores throughout the 1960s.

In January of 1963, Walter P. Babich came to Irwin & Leighton as Chief Engineer. A former Lieutenant in the United States Army, Walt graduated from the City Col-lege of New York and earned a law degree from the University of Denver. He was a Professional Engineer licensed in Pennsyl-vania and New York and was admitted to the Colorado Bar. Within a year of joining the company, Walt was elected Vice Presi-dent. Walt would later lead the company following the 1978 retirement of Bill Ol-mstead.

The 1960s also saw Charles R. Vail join Irwin & Leighton. A Drexel engineering graduate and veteran of the United States Air Force, Charlie would become a Vice President and be instrumental to the suc-cess of the company’s operations until his retirement in 1987.

The 1970s proved to be a very dynamic period for Irwin & Leighton. The company undertook more than 100 projects in ten years, across many sectors and for many notable organizations. Irwin & Leighton built three signifi cant projects for the University of Pennsylvania: The Wharton Graduate Center, Presbyterian Medical Center, and the Class of 1923 Hockey Rink. It also constructed landmark facilities such as the Telephone Exchange Building near the Expressway in Philadelphia.

During the 1970s, Irwin & Leighton led the way in healthcare construction. The company undertook thirteen major hospital projects throughout the area, working with many leading architectural fi rms such as EwingCole, Robert D. Lynn, and others.

1970s 1980s1970 1980

In 1971, Edward S. Babcock joined Irwin & Leighton. An Eagle Scout who had earned a degree in Build-ing Construction from Virginia Polytechnic Institute, Ed had completed two summer internships for the company, and was employed full-time after graduating. In many ways he is the epitome of Irwin & Leigh-ton’s values, having exercised the opportunity for personal growth Irwin & Leighton offers to talented and motivated employees. Ed, who has never worked for another company, has progressed through virtually every operations position to his current position of President and Chief Operating Offi cer.

In 1974, Irwin & Leighton constructed, as its new headquarters, The Irwin Building on 460 North Gulph Road in King of Prussia, Pennsylvania _ after nearly 50 years at 1505 Race Street. The fi ve-story building was sited on part of the estate of Mr. Irwin. In 1979, the company would build The Leighton Building on the same site.

1978-1985

Walt Babich, Vice President of Operations for some time, was named Presi-dent upon Mr. Olmstead’s retirement in 1978. As President, Walt used his experience to rejuvenate the company, resolving to take on and excel at “doing only the work we can handle.” His effectiveness as a leader served to preserve the company’s high performance standards.

In 1979, James F. Brecker, Jr. was hired as Chief Estimator. Jim graduated from Saint Joseph’s College and served in the United States Marine Corps for three years during the Vietnam era. A native Philadelphian, Jim left a position

with a West Coast construction fi rm to join Irwin & Leighton and return home. His fi rst project for Irwin & Leighton was the anchor Bloomingdale’s department store at the King of Prussia Mall, an innovative structure that represented the retailer’s entry into the Philadelphia market.

Jim would later become the leader of Irwin & Leighton, and currently serves as Chairman and Chief Ex-ecutive Offi cer.

Strong relationships with academic and medical institutions continued to provide an abundance of work for the fi rm during the 1980s. In addition, technological changes led to increased corporate and industrial construction activity for contemporary technology leaders such as Digital Equipment Corporation, IBM, Mobil Oil Research & Development and Union Carbide Corporation.

1985-Present

In 1985, Walt Babich retired and Jim Brecker, who was serving as Vice President of Estimat-ing and Purchasing, was named head of Irwin & Leighton. His leadership has been marked by his calm practicality and realistic optimism, as well as his strong focus on long term relationships with quality customers and employees alike.

In 1985, The Irwin and The Leighton Buildings were sold. The company remained in The Irwin Building until it relocated in 2000 to its current headquarters at 1030 Continental Drive in King of Prussia.

WALTER P. BABICHPresident, 1978-1985

A BRIEF HISTORY OF OUR COMPANY / xi

The organization operated as a partnership from 1985 un-til 1987, when it reincorporated.

1985 marked the addition of Harry R. Rogers as Irwin & Leighton’s Comptroller. Harry received his undergraduate degree from The Pennsylvania State University, earned a MBA from California State University, and is a CPA with a distinguished athletic background. He has been instru-mental in guiding the fi nancial operations of the company through its continued growth.

In 1986, David O. Himmelberger joined the company as a Project Manager. Dave’s background included service in the United States Navy and experience in the construction of nuclear and fossil-fueled power facilities. He has been responsible for many major projects, and has been heavily involved in Irwin & Leighton’s marketing efforts. Today, Dave is part of Senior Management.

The 1990s were a time of intense activity and growth for Irwin & Leighton. The company was particularly busy with established customers such as Princeton University, Children’s Hospital of Philadelphia, Lafayette College,

Brown Printing and the General Electric/Martin Marietta/Lockheed Martin organizations. During the 1990s, Irwin & Leighton completed 15 projects for Children’s Hospital, 21 for the “General Electric” orga-nizations and 22 for Princeton University.

During the same time, Irwin & Leighton also earned business from new customers such as State Farm Mutual Automobile Insurance Company, Education Management Corporation, Saint Joseph’s University, and Princeton Theological Seminary as well as the leading retailers of the day: Wal-Mart, Target Stores, Home Depot and Lowe’s. These organizations have been very important to the company’s operations since they became customers in the 1990s.

In the new millennium, as the result of good leadership, consistent performance and exceptional service, the company has been very active with its established customers. Perhaps most symbolic of the continuing strength of Irwin & Leighton’s relationships with long term customers is Princeton University’s award of its Jadwin Hall renovation project to the company in 2009. Jadwin Hall was Irwin & Leighton’s fi rst on-campus project for the University some forty years ago. Irwin & Leighton’s selection was, therefore, very gratifying to the organization.

Since 2000, Irwin & Leighton has also earned important new customers, such as Cabrini College, Pru-dential Life Insurance, Kohl’s, Lehigh Valley Hospital, Muhlenberg College, and The Bryn Mawr Trust

Company. In addition, it has made new inroads with the pharmaceutical industry by working for Sanofi Pasteur, Bayer, Alcon, Wyeth, and Pfi zer.

Signifi cantly, and on the strength of references from current clients, Irwin & Leighton has been entrusted with prominent projects from other new customers, such as The Duke Farms Foundation, The Coriell Institute, Reading Eagle, Villanova University and ReCap (a consortium of Columbia University, The New York Public Library, and Princeton University).

Plans for the future have begun in the new millennium as employees have been promoted to leadership posi-tions at the operating level to help ensure Irwin & Leighton’s continued growth and prosperity.

Today, Irwin & Leighton’s daily operations are guided by its Mission Statement and Corporate Values, which refl ect the great traditions of the organization and its promise for the future.
