In survey responses for the 2021 ENR’s Top International Contractors and Top International Design Firms rankings, companies reported infrastructure development and urbanization as driving forces behind some of the fastest growing global construction markets.
作为设计公司重组操作pandemic-ready, contractors are equally busy managing new project risks while also readying for a boom of new infrastructure projects in regions such as Asia, Australia, Europe and the U.S.
然而，对于许多公司而言，该地区呈现出长期业务增长的最大潜力是非洲。纽约市ARUP副主席Tristram Carfrae说：“非洲是最大的机会。”“随着人口的增长和城市化，它根本拥有将来建设的最大潜力。”
非洲开发银行集团估计，在Covid-19去年造成的2.1％的收缩后，非洲的真正GDP今年将增长约3.4％。该银行称，该大陆正处于“半个世纪以来最严重的经济衰退”之路。意大利Gruppo ICM的副总裁兼业务发展经理Giovanni Dolcetta说，如果承包商想在非洲不断增长的建筑市场中打破地面，他们将需要了解许多国家的外部和内部风险。
“Although the African market’s dynamics are very peculiar—and sometimes, the time for a tender to be expedited is very long—we see Africa as one of the most promising markets at the moment,” Dolcetta says. “The African continent is also a source of huge possibilities: many infrastructures are to be built, most of them financed by the European Investment Bank, various development banks and funds. Given our longstanding presence in Africa, we are following them.”
The following five projects being undertaken by firms appearing on ENR’s Top International Contractors and Design Firms lists highlight the multiple types of infrastructure developments underway on the continent.

Long experience working in Africa prepared DRA Global to deliver during COVID-19. “We delivered projects in Africa during the Ebola outbreak so we have an idea of some of the requirements,” says Senior Vice President Christo Visser. Strict quarantine measures required a major commitment from on-site staff. “Some of them couldn’t get home for around six months to South Africa due to travel and quarantine restrictions,” says Visser. “Their and their families’ commitment have been absolutely admirable.”
该地点围绕着黄金加工厂，该工厂将使用重力和碳素叶状工艺提取黄金。它添加了浸出剂，稀氰化物溶液和活化的碳和水的混合物。浸出剂从矿石中除去黄金，然后被碳吸收。该工厂的目标是每年生产130,000盎司的黄金。
