    Cibecr. (palm tree, en.) – Borassus aethiopum

    Cibe is the vulgar name in crioulo (gw.) for the palm tree Borassus aethiopum which is typical from the Northern and Eastern regions of Guinea-Bissau (Diniz, 2012). Cibe timber is mostly used in civil construction in the form of beams (rachas, pt). Its trunk can reach up to 5 meters hight (and even more) and its section allows to extract 4 to 8 squared-section beams that are used fo building structures such as roofs and/or porches. Cibe was one of the primary materials used to build the strategic villages during the liberation war in Guinea-Bissau (1963-1974), especially employed in roof making. Nevertheless, different ethnic groups made (and still make) use of cibe in vernacular architecture too (Blazejewicz et al., 1983).

    Summary

    The construction of mining camps in late colonial Central Africa, specifically in Lunda (Angola) and the Copperbelt (encompassing parts of Zambia and the Democratic Republic of Congo), presents a complex narrative that questions the multifaceted roles of laborers within these colonial enterprises. This paper examines the conditions, contributions, and agency of workers engaged in the construction of housing and infrastructure under the rule of the Belgian Union Minière du Haut- Katanga (UMHK) and the Portuguese Companhia de Diamantes de Angola (Diamang), between the 1920s and 1970s, revealing a critical dimension of colonial exploitation, social dynamics, and resistance from the building site.

    Workers and families in Lunda and the Copperbelt were pivotal to the construction of mining camps, yet their contributions are frequently overshadowed by the broader narrative of colonial expertise and development. Despite challenging conditions, laborers demonstrated significant skill in their construction efforts. Traditional artisans, with expertise in masonry, carpentry, and other crafts, played a crucial role alongside large groups of still “invisible” men and women. They were often tasked with building their own housing, using a combination of traditional construction techniques and new methods introduced through colonial influence. This self-construction not only mitigated the inadequate housing provided by the companies but also reflected – to some extent – the laborers’ adaptation to new materials such as brick, corrugated iron sheets, and imported cement. The use of local materials like mud, straw, and wood, along with the incorporation of European architectural elements, led to the emergence of hybrid forms of housing that were both practical and culturally significant.

    Against this common corporate backdrop – shaped by strong cross-border and inter-imperial relations between UMHK and Diamang –, this paper questions the similarities and differences between mining camps, laborers, and building sites in Elizabethville (now Lubumbashi) and those in Lunda. These sites had different conditions and environments influenced by varying colonial administrations, mining company policies, and local contexts. While Elizabethville developed into a significant urban center, with diverse socio-cultural influences and a mix of populations from various regions, the Lunda region was arguably shaped by more dispersed and rural mining settlements. How were housing, construction methods, and technologies affected by these circumstances? What did the building site (un)cover about authorship and knowledge transfer? Were the construction yards places for the formation of cosmopolitan communities?

    Summary

    The Benguela Railway represents one of the most significant mobility
    infrastructures developed during the Portuguese colonial period in Angola. The railroad was constructed between 1883 and 1931. The primary objective of the project was to establish a transportation network connecting the Lobito Port in Angola to the mineral- rich region of Katanga in the southern region of the former Belgian Congo. The construction was overseen by a private English company, yet it consistently received substantial support from the colonial state, particularly in terms of recruiting labor.

    A substantial body of research has been conducted on the political, economic, social, and territorial impacts of the Benguela Railway. The project’s promotion facilitated significant inter-imperial connections, the establishment of new settlements along the route, and the creation of an important transportation corridor that would serve a large area extending over 1,800 kilometers. However, the role and building skills of the thousands of African workers who participated in the construction of this line and associated buildings remain to be evaluated.

    This presentation aims to examine the impact of African workers on the building sites, mobile yards, and tasks along the construction of the Benguela Railway. The diversity of political, economic, and technological factors in this case study will be employed to examine the nature and evolution of the concept of “skill”. In particular, the paper will focus on the types of skills developed by the workers and the changes in discourse surrounding those skills over time and across diverse geographical locations. What insights can be gained from a more nuanced perspective that extends beyond the dichotomy of skill versus unskilled? The research will identify and compare information from different sources, including reports produced by the company and colonial inspectors, drawings, and photographs.

    Summary

    As atividades extrativas da Diamang numa ampla região concessionada no distrito da Lunda, no nordeste de Angola, entre as décadas de 1910 e 1980, exigiram a construção de estruturas em diversas escalas, programas e contextos. Este artigo analisa a produção de habitação para os trabalhadores da companhia mineira, inquirindo os modelos desenhados e adaptados ao território, a diversidade de materiais de construção, assim como os processos de apropriação e contestação que os permearam. Cruzando diversos períodos do colonialismo português em África, o artigo explora agendas transversais que desafiam leituras dicotómicas e padronizadas dos modos de habitar. Entre centenas de aldeias e povoações, habitadas por milhares de trabalhadores e famílias, sobretudo oriundos de várias partes de Angola e Portugal, a Diamang procurou criar um «dialeto corporativo» que, contudo, esbarrou amiúde na ambivalência entre imagéticas urbanas, tanto por parte do poder colonial como por parte das comunidades locais.

    Summary

    During early 20th century European colonialism in Africa, mining companies were set up as key vehicles for the exploitation and extraction of the interior regions. The colonial powers granted large concessions to these enterprises, giving them control over resources and trade in exchange for investment in infrastructure. Within the scope of these operations, railways played a pivotal role in facilitating the transport of trade and people, as well as establishing territorial connections. The expansion of these lines served the economic interests of both the colonial powers and the companies, while having a major weight on the landscape through the physical presence of the rails and the creation of new dynamics of mobility.

    This presentation focused on the mining networks between Angola and the Belgian Congo, established under the auspices of the Societè Generále de Belgique, to question the wider and long-lasting socio-spatial implications of the construction of railway lines, considering the multiple agents and agendas involved. It explored the roles played by Union Minière du Haut Katanga, Forminière and Diamang in planning, building, and using railways between the two territories. These were complex and multifaceted connections, involving the railway routes’ layout – from the decauville lines for local transport to the trans imperial connections provided by the Benguela Railway between Katanga and Lobito –, the displacement and mobility of workers in the production of these infrastructures and through their use, the employment of new technologies and construction materials and the adaptation by local populations living near the lines.

    Summary

    The discipline of architecture, when dealing with Public Works associated with colonialism and territorial occupation, still focuses on the analysis of the constitution of the design teams, of the colonial Public Works (CPW) offices, of the architects and engineers themselves. This focus on the “designing elite” misses a critical input to these Public Works, namely the labour force responsible for realising these structures. As such, critical questions about the labour force engaged in the spatialization of architectural plans are still missing: who were those workers? What ethnic groups did they come from? How did they emerge in contingents that could aggregate a few thousand individuals? What was their recruitment like? What expectations did they have? How were they paid? What training did they receive? What repercussions did these (often compulsory) work experiences have? What conflicts did they provoke in colonial societies? How did they resist recruitment? How did they collaborate? How to deal with this legacy?

    Among other milestones and outcomes, ArchLabour will create and promote an online database to make research material and resources available. One of ArchLabour’s main goals is to collect and co-produce information about architectural culture, particularly CPW, and share and discuss it with the community. The database will follow a dynamic structure to engage both ArchLabour researchers and different users who may register, including other scholars interested in similar topics and anonymous persons with experiences linked to colonial construction, territorial infrastructure and urbanization. The platform will be used to share information (personal archives, photographs, video, audio and written testimonies) and it is expected to become a long-term tool of wide-ranging resources to facilitate discussion between scholars, experts, agents and users.

    Summary

    The Mabubas Dam, built in Angola between 1948 and 1954, was the first large infrastructural work promoted by the Portuguese state in Africa to sustain colonialism against the growing local and international scrutiny after World War II. Its 70-metre length, located in an isolated place near Luanda, resulted in an extensive and highly dynamic building site.

    Acknowledging the political, social and technological circumstances in the Mabubas case, this presentation aimed to investigate the overlooked histories of colonial construction spaces to contribute to broader debates on building site conditions. As a fixed construction yard, later giving rise to a new settlement, the Mabubas Dam offers an intricate research ground, merging thousands of people, different tasks and labour hierarchies. Three significant relationships were explored: the intricacies between European and African workers, the tensions among African communities and the manifold interactions across the specialization strata, namely the hostilities towards workers from other colonial geographies, as the Cape Verdean labourers, considered more “civilized” and therefore more “skilled”.

    Drawing from the thought-provoking “non-simultaneity” approach, by Heine and Rauhut, the presentation aimed to add new perspectives to the field from the peculiarities and complexities of colonial construction sites. While European building sites were based on familiar know-how systems and techniques, the construction spaces produced under colonialism arguably had a greater level of uncertainty, frequently exposed in reports. The colonial authorities did not control the traditional skills of the African communities nor the local materials, thus having to deal with unpredictable outcomes. Besides presenting a critical mapping of the colonial construction site, the presentation analysed its materialization in the archive. What information can be gathered in reports – from income to architectural design? What layers are absent (namely concerning women’s presence or building constraints)? How can these conditions contribute to more nuanced architectural histories?
