Vergehorn Construction Works (Commonspeak: Vergehorn Bauwerk Companë) is a privately held Aerlan construction and civil engineering company headquartered in Zareda. It was founded in 1724 AN by the engineering and surveying cadre that had just completed the Mount Kane to Zareda segment of the Great Aerlan Highway, and it only builds, taking no design, planning, or property work. The firm is the only contractor in Aerla with a permanent high-altitude tunneling division, and it developed the Achterberg method for placing concrete in cold weather above 2,000 meters. In 1757 AN it employed about 11,400 people and reported revenue of ₣890 million.
The company builds mountain highways, tunnels, dams and their associated hydroelectric civil works, long-span bridges, and avalanche galleries, and it carries out slope stabilization across the Keltian interior. It takes its name from the Vergehorn massif, at 6,017 meters the highest peak in Aerla, where much of its early work was done. Beyond Aerla, the firm works in the Wechua highlands of Nouvelle Alexandrie, in the mountains of Anglien, and in Natopia.
History
The Great Aerlan Highway was built between 1715 AN and 1728 AN in four segments to link the more isolated parts of Aerla to the interior road network. The third of these, running from Mount Kane to Zareda through high ground, was the hardest to build. Its chief engineer, Konrad Achterberg, kept the surveying and engineering teams together when the segment opened in 1724 AN and incorporated them as a private firm at Zareda in the same year. The segment's high sections had been worked in part by the convict battalions of the Penal Reserve Labor System, and Vergehorn's early sites relied on that labor until the system was abolished in 1750 AN, after which the firm rebuilt its workforce around paid site crews.
Through the following decades the company moved from mountain roadwork into tunneling, dam construction, and the long-span bridges that high valleys require. Aerla's rivers are fast and steep, and the firm built much of the civil work for the small hydroelectric stations raised along them. The problem that shaped the company was cold: concrete placed at altitude in low temperatures cures poorly and cracks. A mountain dam in 1733 AN first forced the issue, when a full season's concrete cracked before it cured. In answer, Achterberg's engineers developed a system of heated aggregate, insulated formwork, and staged curing that allowed reliable placement above 2,000 meters, and the technique came to be known within the trade as the Achterberg method. Leadership later passed to Anneliese Achterberg, who chairs the firm as of 1757 AN.
Operations
Vergehorn Construction Works restricts itself to construction and civil engineering. It does not offer architecture, master planning, or property development, and it subcontracts or declines work that falls outside heavy building. Its core capabilities are mountain highway and tunnel construction, the civil works for dams and hydroelectric stations, long-span bridges, avalanche galleries that shield roads and rail from snow, and the stabilization of unstable slopes.
Its high-altitude tunneling division, the only permanent one in Aerla, holds the drilling crews, ventilation plant, and cold-weather equipment that mountain tunneling demands. Paired with the Achterberg method for concrete, the division lets the company take work at elevations that seasonal contractors cannot reach for most of the year. Because the Mount Kane segment that formed the company ends at the seat of the Aerlan Nazarene Church, the See of Mount Kane, Vergehorn has long built the access roads, funiculars, and slope defenses that serve the church's high monasteries in the northeastern mountains, leaving the fabric and its restoration to specialist conservators.
Operations abroad
Vergehorn Construction Works takes mountain construction contracts outside Aerla. It has built in the Wechua highlands of Nouvelle Alexandrie, where the terrain resembles the Aerlan interior, and in the mountain country of Anglien, and it takes civil works contracts in Natopia. Its slope stabilization and avalanche galleries apply abroad the same alpine methods it uses at home, and its high-altitude tunneling division handles most of these foreign contracts.
Organization
The company is privately held and has remained under the founding family's control since 1724 AN, with its headquarters in Zareda near the Mount Kane to Zareda highway it was formed to build. As of 1757 AN it is chaired by Anneliese Achterberg, with Bertram Kolditz as chief executive and Ivo Radev as chief engineer. It employed about 11,400 people that year, the larger part of them site crews rather than office staff.
