    Waterford School, Eswatini

    WATERFORD SCHOOL, ESWATINI

    Waterford School is situated on a hill four miles from Mbabane, the principal town of Swaziland (British Protectorate), now the kingdom of Eswatini. In defiance of apartheid, it was founded by Michael Stern as a multi-racial secondary school for boys, regardless of their ethnicity, religion or income. It opened on February 2, 1963, inspired by British institutions and sponsored by private patrons. The 200-acre site is located 4,500 feet above sea level and 500 feet above Mbabane. “Rondavels”, a pre-existing group of buildings, served as the first classrooms and other accommodation. The new complex occupied the hills, leaving the flat area free for sports facilities. Access was via a difficult road, which gave the site an atmosphere of isolation.

    01. Plan & Construction

    Pancho Guedes was the architect of the first phase, on a pro bono basis (1961-1972). A drawing by former student Pedro Guedes dated the different phases of the first nucleus, structured from a level corridor/open-air gallery, with perpendicular buildings following the slope: one-storey dormitories, ending with two staff/teachers’ houses (1963-1964); three blocks for collective activities, including meals (1964-1966); two-storey dormitories (1967-1970), culminating in a residence (1970). The library, two classroom blocks and laboratories were built nearby. A girls’ dormitory was built away from this first core but near the “Rondavels” (1969-1972). As the complex expanded, the internal functions changed, ensuring that the school could be used while the building work continued. 

    02. Labour

    James Richardson, an experienced British carpenter, who settled with his family at the beginning of the school’s construction, was one of the pillars of the enterprise. He was part of the team that coordinated a workforce of local labour, augmented by mostly of Waterford residents – pupils, staff and teachers. They were joined by Mozambican workers brought in by the architect Pancho Guedes and the Portuguese builder Machado, who replaced the first contractor of South African origin. Students and teachers performed unskilled tasks, supervised by more qualified laborers. The different languages that coexisted on the building site reflected the heterogeneity of the agents involved. 

    03. Skills & Technologies

    The initial construction work consisted of clearing the land of granite boulders. The sequence of tasks included making sun-cured sand and cement bricks and molding them on site; laying foundations and compacting the earth; formwork and concreting; assembling cages of reinforcement from straight steel rods; pouring concrete roof slabs; and laying roof tiles. The construction systems mixed the Portuguese tradition practiced in Mozambique with the South African one, the latter using industrially produced components such as standardized steel windows. Although the construction was solid, the finishes were precarious, as a result of unskilled labor (including students) in tasks such as painting. At least one mural was frescoed in one of the dormitory courtyards.

    BENGUELA RAILWAY, ANGOLA

    The Benguela Railway, built between 1903 and 1931, was one of the most important mobility infrastructures developed during European colonialism in Africa, bringing together Portuguese, British and Belgian interests. The railway is 1,866 km long, with almost 60 stations, and connects Lobito, on the Angolan coast, with Luau, a small town near the eastern border – and then extends to the Katanga mining region in the Belgian Congo.

    01. Plan & Construction

    Construction of the Benguela Railway began on 1 March 1903 and involved two British contractors with extensive experience of building railways in Africa. George Pauling & Co. started the earthworks and imported some rails from England. Th following year, Norton Griffiths & Co. continued the process, completing the first section of 197 kilometres to Cubal in 1908. Pauling was later reappointed and completed the railway to Luau in 1929 (with a long hiatus between 1913 and 1920 due to the economi effects of the First World War). Other smaller contractors, such as the Italian Vigano, also worked on some sections.

    02. Labour

    For the first decade, the work was carried out by 7,000 men working day and night in continuous shifts. Most came from abroad, including Ghana, Liberia (especially “kroo boys”), French West Africa (Senegal), Cape Verde, the Belgian Congo and South Africa. About 2,000 Indians (known as “coolies”) were recruited in Natal and India, some with their families. From 1912 there was a shift towards using local labour in Angola. By this time, construction work was being carried out by smaller teams. Some 2,200 Africans were involved in clearing land, earthworks, steelwork, bridge and telegraph construction and bricklaying. Their wages were “between 100 and 140 réis” – almost half the amount quoted by the Portuguese colonial government in 1900, perhaps because of the “voluntary” position of these men.

    03. Skills & Technologies

    Each section of the line faced different topographical conditions and logistical problems, requiring different techniques, materials and numbers of workers. The first section, for example, involved the construction of an advanced “rack” system. Unlike the “European” personnel, the African workers had no formal qualifications and were not expected to have experience in railway construction. Their assessment by the railway managers was based on ethnic prejudice as well as physical and social ability. Some groups, such as the Kroo, were valued for their physical strength, while others, such as the Quilengues men, were valued for their commitment to the work.

    MABUBAS DAM, ANGOLA

    The Mabubas Dam (1948-1954) – formerly known as Capitão Teófilo Duarte Dam, after the name of the Portuguese Minister of Colonies at the time –, was the first large hydroelectric work promoted by the Portuguese state in Africa. Its construction started in February 1948 at an isolated place near Luanda, Angola.

    01. Plan & Construction

    The project included a gravity dam with a triangular profile and a curved plan: 40 meters high, 282 meters long, and 63,000 m3 of concrete. Portuguese, French and British construction companies were involved in the production, such as Luso-Dana, Neyrpic Portuguese, Obras Metálicas Electro-Soldadas (OMES), Sociedade de Electricidade e Fomento, Construções Especiais, Cimentation Company, The S. Morgan Smith Company and Westinghouse Electric Company. After some failed attempts, the Portuguese state hired the British firm Sir Alexander Gibb & Partners, which re-evaluated the initial plans in 1944, and continued with French and Danish experts.

    02. Labour

    At its peak, the construction gathered 1,053 workers, described in inspection reports as Indigenous and Europeans. “European” and “assimilated” labourers made up the most qualified group; yet accounting for no more than 15% of the workforce. Unskilled positions were held by the remainder of the workers, including 17% “volunteers”. The movement of people at the yard increased over time, with hundreds of men arriving and leaving every month. Inside Angola, the contingents came from Camacupa, Bié, Alto Quanza, Huambo, Dande, Zombo, Pombo, Ambrizete, Dembos, Cambo, Duque de Bragança and Malange, among others.

    03. Skills & Technologies

    Over 30 fields of expertise took part in the construction, from engineers, doctors, nurses, accountants, executive managers, assistants and cooks to construction managers, foremen, toolmakers, bailiffs, warehouse keepers, electricians, motorists, bricklayers, machinists, plumbers, electricians, painters, carpenters, miners, ditchdiggers, quarrymen and servants. Both European and African laborers had to deal with many materials and techniques that combined traditional methods with cutting-edge technology. The simultaneity of systems, materials, and skills was a significant feature of the building site and a decisive factor in the success of the work.
