• Water conveyance main — A formal variant or secondary terminology for the noun 'aducție' (adduction), denoting the complete system of structures, aqueducts, main channels, or large-scale pipelines designed for the capture and conveyance of fluids (especially potable or raw water) from a collection source directly to distribution nodes or treatment plants. In older medical or academic treatises, it was also occasionally used to describe the biological inward movement of limbs.
• Scour — The act of scouring and its result; a hydrodynamic phenomenon of local erosion, washing away, and excavation of a riverbed or soil at the base of a hydraulic structure, such as bridge piers or dikes, under the direct action of strong currents. This structural process can jeopardize the stability of the entire foundation if consolidation measures are not applied.
• Alignment — A straight line marked by fixed reference points used for guiding, laying out, or regularizing spatial elements; a geometric direction along which buildings on a street, trees in a plantation, or troops in a formation are aligned. In an urbanistic and legal sense, it represents the boundary separating public domain from private properties, determining the street configuration.
• Construction site — The precise plot of land, site, or delimited portion of the earth's surface where a building, technical facility, or military camp is located, built, or scheduled to be set up. It represents a fundamental reference element in cadastral documentations and building permits, defining the physical and legal framework of the investment.
• Water intake — A technical term designating a specialized engineering structure intended for capturing, intake, or managed diversion of a water flow from a natural course, canal, or basin, for supplying irrigation systems, hydroelectric plants, or drinking water networks; also, the term is sometimes used in topography and transport to indicate the width of the land strip definitively occupied by a railway or a public road.
• Anchorage — A device, part, or structural assembly used to tightly secure a machine, a building element, a pole, or a cable to a solid foundation or a fixed support. In civil engineering, it represents the system that ensures the transmission of tensile stresses from structural elements (such as the cables of a suspension bridge) to the foundation block.
• To coat with bitumen — To coat, cover, or mix mineral aggregates (crushed stone, gravel, sand) with a hydrocarbon binder (fluid bitumen or bituminous emulsion) to obtain asphalt mixtures for road surfaces. In civil engineering, this structural process ensures the cohesion, impermeability, and mechanical resistance of bituminous layers applied to highways or public roads.
• Riprap — A massive construction element made by heap-piling, orderly laying, or chaotically dumping large blocks of raw stone, boulders, or prefabricated concrete elements (such as stabilopods). In hydrotechnical and civil engineering, this heavy structure is used for building dikes, dams, riverbank reinforcements, protections against wave or torrent erosion, and for solid underwater foundations.
• Diaphragm girder — A secondary horizontal beam, rigid connecting piece, or structural stiffening element mounted transversally between two parallel main girders, aiming to maintain their distance constant, prevent their twisting or buckling, and uniformly distribute gravitational or dynamic loads. This element is essential in the construction of steel bridges, viaducts, and complex roof frameworks.
• Aqueduct — An old and regional technical term used as a partial synonym for aqueduct; a civil engineering structure, canal, massive flume, or large pipe built to transport and guide the flow of drinking water from a distant source to a settlement or industrial facility.
• Aqueduct — A complex system of channels, large-scale pipelines, and civil engineering structures (often in the form of bridges suspended on arches) designed for collecting and transporting potable water over long distances, from the catchment source to a city's distribution network. It represents a major hydrotechnical infrastructure work.
• Arcare — The act of arching and its result; a physical, geometric, or structural process through which an object, line, surface, or construction element is bent, curved, or shaped into the form of an arch. In civil engineering and architecture, it represents the curved configuration of load-bearing structures to optimally distribute gravitational loads.
• Arched — Having a curved, bent, or vaulted shape resembling an arch; a structural or geometric element specially configured to distribute weight or to follow a concave or convex trajectory. In architecture, it describes an opening, ceiling, or bridge supported by mechanical arches.
• Arcuda — A proper geographical name designating a locality in Giurgiu County, Romania, as well as a famous water treatment plant belonging to the utility network of the Bucharest municipality. Structurally, the hydrotechnical node at Arcuda, situated on the Argeș River, represents an essential strategic point for national municipal infrastructure, possessing a technical history that dates back to the late 19th century.
• Asphalt — A natural or artificial mixture of bitumen and granular mineral matters, black or dark brown in color, structurally used as an impermeable binder for road paving, waterproofing buildings, or manufacturing protective varnishes. In colloquial sense, it designates the roadway surface of a modernized street or highway.
• To asphalt — To cover a street, a highway, a yard, or an industrial platform with a layer of asphalt to ensure a flat, durable, and waterproof surface. In a structural sense, it defines the execution of road finishing works by compacting bituminous layers according to technical projects.
• Asphalt pavement — The totality of technical paving or covering works of a road, pedestrian, or industrial surface with a compact layer of asphalt; the result of the asphalting operation, viewed as a finished structure. It is a technical term more rarely used in current speech, usually replaced by the noun of action 'asfaltare'.
• Asphalted — Having been covered, paved, or treated with a protective layer of asphalt (bituminous mixture); a road, driveway, or sidewalk mechanically engineered to ensure a flat, durable, and waterproof surface. This structural phenomenon facilitates road transport under high safety and comfort conditions, preventing soil degradation caused by climatic factors.
• Asphaltic — Containing asphalt, having the characteristics of asphalt, or referring to it; bituminous. In a structural and geological sense, it describes rocks, deposits, or industrial mixtures rich in heavy hydrocarbons, used as raw material in refineries or directly in road construction and insulating materials industries.
• Course of masonry — 1. (In construction and architecture) A continuous horizontal layer of stone blocks, bricks, or other masonry materials, laid at the same height within the structure of a wall. 2. (In geology) A layer of sedimentary rocks deposited uniformly, characterized by the same lithological or paleontological composition. 3. (In law and history; plural) A court of assizes, session, or periodic judicial structural gathering where criminal trials of outstanding severity were judged.
