The Borden Base Line is a 39,009.73 feet (7.42 miles ) survey line through the State of Massachusetts. The line was the first project of its kind undertaken in America and its establishment was the key element for Massachusetts pioneering mandate to survey the entire state. 

The challenge was to use trigonometrical principles, instead of astronomical observation alone, to provide greater accuracy in surveying large areas.

The Triborough Bridge Project is a three-branched waterway crossing that connects Manhattan, the Bronx, and Queens at a junction of the East River and the Harlem River in New York City. The complex structure includes a suspension bridge from Wards Island to Queens, a vertical lift span from Randall's Island to Manhattan, a fixed span (designed to be convertible to a lift span) across the Bronx Kills, viaducts, and an innovative three-legged roadway interchange.

Central Pacific Railroad served as the Western terminus of America's first transcontinental railroad, passing through the formidable Sierra Nevada Mountains. In all, 15 tunnels were blasted through solid granite. 

Thousands of Chinese from Kwantung Province were recruited by Central Pacific Railroad Company and became known for their diligence and hard work. In the second year of construction, nine out of ten workers on the CPRR were Chinese.

Tipon is a self-contained, walled settlement that served as an estate for Inca nobility. Located 13 miles down the Huatanay River Valley by the Inca capital of Cusco, the 500-acre archeological site provides knowledge and better understanding of the pre-historic Inca and their irrigation and building skills. The site represents great mastery of irrigation and hydraulic technology. The civil engineers of Tipon designed buildings, 13 integrated central terraces, waterworks, hundreds of other terraces and massive structures to be visually and functionally harmonious with their surroundings.

Opened in 1835, the Thomas Viaduct was the first multiple-arch, stone railroad viaduct in the United States. The viaduct is composed of eight arches each with a clear span of about 58 feet. The viaduct has an overall length of 614 feet and a height of about 60 feet above the Patapsco River. Construction of the viaduct began in August of 1833, and a ceremony marking its completion was conducted on July 4, 1835. The viaduct was constructed for the Baltimore and Ohio (B&O) Railroad and is named in honor Philip E. Thomas, who served from 1827 to 1836 as the first president of the B&O.

Thames Tunnel

By the turn of the 19th century, London's streets were clogged with traffic. Over 3,700 passengers used the Thames River's main boat crossing each day, while wagons and carts were forced to cross via the London Bridge, two miles away. Building a bridge would further impede shipping on the already-crowded Thames; a tunnel was the obvious alternative.

The first attempt at a tunnel in the present location began in 1807. The excavation had proceeded only 1,000 feet-using traditional mining methods-when crews reached a layer of quicksand and were forced to stop.

Built between 1819 and 1826, the Menai Bridge was the major structure on Britain's strategically important Holyhead Road connecting London with Holyhead and by sea to Ireland. Designed by Thomas Telford, the bridge's main span was 579 feet from tower to tower, the longest that had ever been attempted at this time. He used four sets wrought-iron eyebars to suspend the deck. These were made by William Hazledine at his Upton forge near Shrewsbury. Each bar was carefully tested in his Coleham shops before being pinned together and lifted into place.

The Tehachapi Pass Railroad Line was cut through solid and decomposed granite by about 3,000 Chinese laborers using nothing more than picks, shovels, horse drawn carts, and blasting powder. This line, which rises from the San Joaquin Valley and through the Tehachapi Mountains, originally included 18 tunnels, ten bridges and several water towers to accommodate the steam locomotives. Completed in less than two years, it was part of the final line of the first railroad to connect San Francisco with Los Angeles.
