Engineering is the use of scientific principles to design and build machines, structures, and other items, including bridges, tunnels, roads, vehicles, and buildings. The discipline of engineering encompasses a broad range of more specialized fields of engineering, each with a more specific emphasis on particular areas of applied mathematics, applied science, and types of application. See glossary of engineering.
The year 1871 in science and technology involved some significant events, listed below.
A rivet is a permanent mechanical fastener. Before being installed, a rivet consists of a smooth cylindrical shaft with a head on one end. The end opposite the head is called the tail. On installation, the rivet is placed in a punched or drilled hole, and the tail is upset or bucked, so that it expands to about 1.5 times the original shaft diameter, holding the rivet in place. In other words, the pounding or pulling creates a new "head" on the tail end by smashing the "tail" material flatter, resulting in a rivet that is roughly a dumbbell shape. To distinguish between the two ends of the rivet, the original head is called the factory head and the deformed end is called the shop head or buck-tail.
The Severn Railway Bridge was a bridge carrying the railway across the River Severn between Sharpness and Lydney in Gloucestershire, England. It was built in the 1870s by the Severn Bridge Railway Company, primarily to carry coal from the Forest of Dean to the docks at Sharpness; it was the furthest-downstream bridge over the Severn until the opening of the Severn road bridge in 1966. When the company got into financial difficulties in 1893, it was taken over jointly by the Great Western Railway and the Midland Railway companies. The bridge continued to be used for freight and passenger services until 1960, and saw temporary extra traffic on the occasions that the Severn Tunnel was closed for engineering work.
Gloucester Railway Carriage and Wagon Company (GRC&W) was a railway rolling stock manufacturer based in Gloucester, England from 1860 until 1986. Products included goods wagons, passenger coaches, diesel multiple units, electric multiple units and various special-purpose vehicles. The company supplied the original fleet of red trains for the Toronto Subway, which were based upon similar vehicles to the London Underground. The company also produced pivoting sections for the Mulberry Harbour for the British War Office 1944.

B. Hick and Sons, subsequently Hick, Hargreaves & Co, was a British engineering company based at the Soho Ironworks in Bolton, England. Benjamin Hick, a partner in Rothwell, Hick and Rothwell, later Rothwell, Hick & Co., set up the company in partnership with two of his sons, John (1815–1894) and Benjamin (1818–1845) in 1833.
Sopogy was a solar thermal technology supplier founded in 2002 at the Honolulu, Hawaii-based clean technology incubator known as Energy Laboratories. The company began its research on concentrating solar thermal energy to produce solar steam and thermal heat for absorption chillers or industrial process heat. The company has also developed applications that incorporate its solar collectors to generate electricity and desalination. Sopogy's name origin comes from industry key words "So" from solar "po" from power and "gy" from energy and technology. The company has its OEM and IPP sales teams along with research and development located in Honolulu, and in 2006 expanded its manufacturing, C&I and oil and gas sales teams in its Silicon Valley facility. Pacific Business News and Greentech Media reported that the VC-funded micro-concentrator solar power firm was shutting down operations based on statements from its President David Fernandez, however Hitachi Power Systems acquired Sopogy in a private transaction in 2014.
Sir William Arrol & Co. was a Scottish civil engineering and construction business founded by William Arrol and based in Glasgow. It built some of the most famous bridges in the United Kingdom including the second Tay Bridge, the Forth Bridge and Tower Bridge in London.
Mather & Platt is the name of several large engineering firms in Europe, South Africa and Asia that are subsidiaries of Wilo SE, Germany or were founded by former employees.

William Ezra Worthen was a Harvard-educated American civil engineer. He was President of the American Society of Civil Engineers in 1887, and elected an Honorary Member in 1898.
Ralph Hart Tweddell was a British mechanical engineer, known particularly for inventing the portable hydraulic riveter, which greatly facilitated the construction of boilers, bridges and ships.
Gloucester Quays is an outlet shopping centre on St Ann Way, Gloucester, in the area of the city formerly known as High Orchard. The outlet is situated close to Gloucester Docks, a historic area of the city.
High Orchard was an industrial area of the city of Gloucester in England that was developed in the 19th century on the former orchard of the Priory of Llanthony Secunda (1136).
