A crane is a machine used to move materials both vertically and horizontally, utilizing a system of a boom, hoist, wire ropes or chains, and sheaves for lifting and relocating heavy objects within the swing of its boom. The device uses one or more simple machines, such as the lever and pulley, to create mechanical advantage to do its work. Cranes are commonly employed in transportation for the loading and unloading of freight, in construction for the movement of materials, and in manufacturing for the assembling of heavy equipment.
The Millau Viaduct is a multispan cable-stayed bridge completed in 2004 across the gorge valley of the Tarn near Millau in the Aveyron department in the Occitanie Region, in Southern France. The design team was led by engineer Michel Virlogeux and English architect Norman Foster. As of October 2023, it is the tallest bridge in the world, having a structural height of 343 metres (1,125 ft).
The Kingston Bridge is a balanced cantilever dual-span ten lane road bridge made of triple-cell segmented prestressed concrete box girders crossing the River Clyde in Glasgow, Scotland.
A box girder bridge, or box section bridge, is a bridge in which the main beams comprise girders in the shape of a hollow box. The box girder normally comprises prestressed concrete, structural steel, or a composite of steel and reinforced concrete. The box is typically rectangular or trapezoidal in cross-section. Box girder bridges are commonly used for highway flyovers and for modern elevated structures of light rail transport. Although the box girder bridge is normally a form of beam bridge, box girders may also be used on cable-stayed and other bridges.
In geotechnical engineering, a caisson is a watertight retaining structure used, for example, to work on the foundations of a bridge pier, for the construction of a concrete dam, or for the repair of ships.
The Saipem 7000 is the world's third largest semi-submersible crane vessel, after the SSCV Sleipnir and the SSCV Thialf. It is owned by the oil and gas industry contractor Saipem S.p.A.
Formwork is molds into which concrete or similar materials are either precast or cast-in-place. In the context of concrete construction, the falsework supports the shuttering molds. In specialty applications formwork may be permanently incorporated into the final structure, adding insulation or helping reinforce the finished structure.
A pile driver is a heavy-duty tool used to drive piles into soil to build piers, bridges, cofferdams, and other "pole" supported structures, and patterns of pilings as part of permanent deep foundations for buildings or other structures. Pilings may be made of wood, solid steel, or tubular steel, and may be driven entirely underwater/underground, or remain partially aboveground as elements of a finished structure.
A kendang or gendang is a two-headed drum used by people from the Indonesian Archipelago. The kendang is one of the primary instruments used in the gamelan ensembles of Javanese, Sundanese, and Balinese music. It is also used in various Kulintang ensembles in Indonesia, Brunei, Malaysia, Singapore, and the Philippines. It is constructed in a variety of ways by different ethnic groups. It is related to the Indian double-headed mridangam drum.
A jack is a mechanical lifting device used to apply great forces or lift heavy loads. A mechanical jack employs a screw thread for lifting heavy equipment. A hydraulic jack uses hydraulic power. The most common form is a car jack, floor jack or garage jack, which lifts vehicles so that maintenance can be performed. Jacks are usually rated for a maximum lifting capacity. Industrial jacks can be rated for many tons of load.
A concrete pump is a machine used for transferring liquid concrete by pumping. There are different types of concrete pumps.
A deep foundation is a type of foundation that transfers building loads to the earth farther down from the surface than a shallow foundation does to a subsurface layer or a range of depths. A pile or piling is a vertical structural element of a deep foundation, driven or drilled deep into the ground at the building site.
The Haukilahti water tower is located in Haukilahti in southern Espoo, Finland. The water tower was built in 1968 and is owned by the Espoo waterworks. The diameter of the tower is 45.3 m and it has two water containers—one inside the other—with a total volume of 4100 m3. The height of the tower is 45.3 m and from sea level 76.3 m.
Slip forming, continuous poured, continuously formed, or slipform construction is a construction method in which concrete is placed into a form that may be in continuous motion horizontally, or incrementally raised vertically.
The Surtees Bridge is a road bridge carrying the A66(T) road east west across the River Tees near Thornaby-on-Tees in the borough of Stockton-on-Tees in the north east of England. The bridge is situated one kilometre upriver from Stockton town centre, just upriver of Surtees Rail Bridge – a rail bridge carrying the Tees Valley Line. Built at a cost of £14.3 million the bridge replaces an earlier Surtees Bridge (1981) that showed signs of distress resulting from excessive settlement.
Indonesia is to be considered as one of the leading countries in science and technology developments. There are numerous examples of notable scientific and technological innovation, developments and achievements contributed by Indonesians. Despite being a developing country, Indonesia is one of a handful nations that have developed their own aerospace technology.

Demolition is the science and engineering in safely and efficiently tearing down buildings and other artificial structures. Demolition contrasts with deconstruction, which involves taking a building apart while carefully preserving valuable elements for reuse purposes.
The Bletchley Flyover is a railway viaduct that crosses the West Coast Main Line (WCML) just south of Bletchley railway station in Milton Keynes, England. It was originally a reinforced concrete railway viaduct that carried the former Varsity line between Oxford and Cambridge from 1959 until its closure in 1968. The flyover was retained, but largely unused until 2021, when the East West Rail Alliance demolished then rebuilt the structure. It reopened for engineering use in early 2022.
