The oil boom of the 1970s caused Lagos, Nigeria’s rapid urbanization, which resulted in a large influx of people moving there in search of work. Due to the city’s expansion onto the mainland, industrial and infrastructure development were encouraged, which increased the state’s GDP and socioeconomic well-being. However, there are also significant drawbacks to urbanization, such as rising infrastructure needs and environmental issues like declining health, poor infrastructure performance, climate change, and energy scarcity. By analyzing professional practices, identifying gaps, assessing the potential of sustainable materials, and suggesting ways to incorporate these materials with better practices for durability, environmental performance, and cost-effectiveness, this study sought to increase the resilience of heavy engineering projects in Lagos. Primary and secondary sources of information were used for data collection. Two sets of questionnaire targeting stakeholders of six purposively selected EIA-heavy engineering projects and construction professionals were administered. Secondary data reviewed regulations, skill gaps, cultural, economic, and infrastructure factors affecting sustainable material adoption. Data were analyzed using descriptive and inferential statistics, particularly Mean Response Analysis (MRA), to derive insights and conclusions. Employed in analyzing the case studies and structured interviews was the OTTR (observe, think, test, and revise) method. SDGs 9 (Industry, Innovation, and Infrastructure), 11 (Sustainable Cities and Communities), and 13 (Climate Action) are all in line with the study’s findings, which add to the continuing conversation on creating resilient built environments. Conclusively, a resilient heavy engineering project is one whose design, construction and operation meet the criteria of sustainability. In achieving resilience in this industry, the sine qua non includes the enhancement of professional practices and adoption of sustainable materials that lead to project management improvements. This paper provides useful suggestions for the government, legislators, sustainability professionals, and sponsors with a view to promoting resilience in Lagos and other quickly expanding cities.
