2. TUNNELING EXPERIENCE

2.1 Competence

Lane has inherited a 95-year history of tunneling experience from S.A. Healy Company (Healy), a tunneling and heavy civil contractor located in Henderson, Nevada. Healy merged with Lane in 2018.

Lane is highly competitive in the tunneling sector because of the resources and proven results from Healy, as well as the global experience from its parent company, Salini Impregilo.

Lane’s acquired tunneling portfolio consists of over 100 miles—more than one half million feet—and more than 200 projects worth billions of dollars. This tunneling experience can be seen throughout America’s largest cities including Cleveland, Portland, Las Vegas, Chicago, New York, Dallas, San Francisco, and Washington, D.C.

2.2 Our Most Valuable Asset

Lane believes in the skills of its people as a key asset of the company to fulfill business goals. In an ever-more-complex world, human capital is a key factor to maintain leadership and provide clients and all other stakeholders with quality performance and results.

3. KEY PROJECTS

Lane’s tunneling works support sustainable infrastructure that helps communities thrive. From clean water initiatives to reliable transportation alternatives, Lane’s experience focuses on improving the quality of life within America’s largest cities.

Lane has recently completed three combined sewage overflow (CSO) tunnel projects and is working on two additional CSO projects; all of which contribute to improving the quality of community rivers and lakes to benefit both current and future generations.

Lane provided a reliable water source to two million residents through the Lake Mead Intake No.3 Shafts and Tunnel, which included one of the world’s deepest subaqueous tunnels. In San Francisco, Lane constructed a subway tunnel that provides a time-saving travel

alternative in one of the fastest growing cities in the country.

Lane’s parent company, Salini Impregilo, builds sustainable tunneling projects throughout the world. In Denmark, they are building the Cityringen Metro, an underground circular line around Copenhagen to transport 240,000 passengers a day and help drastically reduce atmospheric pollution.

In Saudi Arabia, they are building the Riyadh Metro Line 3, the longest line in the new underground system, which will extend underneath the city with a total length of 109 miles for an estimated total investment of $20 billion. Salini Impregilo is also building the first underground line in Doha, in Qatar, under extreme environmental conditions.

TUNNEL WORK HIGHLIGHTS

4. THE LEGACYIt all began in 1890 when railroad entrepreneur John S. Lane started a stone-crushing operation for railroads and streets. By the turn of the century, the road construction business quickly became a success, paving 75,000 square yards of macadamized road (a mixture of stone, sand, and raw asphalt) in 1895 alone. With the invention of the automobile, the demand for roadway improvements skyrocketed, and John S. Lane seized the opportunity by incorporating The Lane Construction Corporation in 1902.

Lane has played a critical role in the development and maintenance of the nation’s infrastructure. In the 1940s, the company expanded into military bases to support the war effort, and in the 1950s and 1960s, Lane helped make the Interstate Highway System a reality, building some of the nation’s most well-known superhighways.

Throughout the 1960s, 1970s and 1980s, Lane expanded its heavy civil capabilities and added many new public/private clients to its portfolio. In the early 1990s, Lane began work on a privately built toll road. In the 2000s, the Company became a leader in public-private partnerships (P3) and innovative financing solutions that moved forward projects that would have otherwise been postponed due to a lack of public funding.

Today, the firm has the resources and expertise to invest in the most complex infrastructure projects in the United States, and build them in a sustainable way.

Backed by Salini Impregilo’s vast global experience, Lane looks toward the future with a focus on improving life for current and future generations.
