Geotechnical engineering is all about giving information about the earth to people who need it for designing sustainable structures like roads, bridges, buildings, and dams. It’s also about protecting the environment and ensuring that construction activities are done in a sustainable way. Waliu Adeolu, the National President of the Nigerian Association for Engineering Geology, believes that the government should take action to prevent unqualified individuals from engaging in construction projects. He emphasizes the importance of proactive measures to address flooding in the country and the need for sustainable construction practices to protect the environment. Adeolu also highlights the role of geotechnical engineering in assessing the impact of human activities on the environment and providing solutions for remediation. He stresses the significance of engaging geotechnical experts in construction projects to ensure safety and avoid potential dangers. Adeolu calls for proper evaluation of construction sites, considering factors like soil type and environmental impact. He emphasizes the need for attention to detail in geotechnical engineering and the importance of implementing the National Building Code to ensure safe and sustainable construction practices. Adeolu also raises concerns about the risk of extinction faced by low-lying coastal cities and suggests the implementation of strong barriers to prevent land encroachment. He advocates for the government to address housing and environmental challenges by cracking down on quackery in the construction industry and promoting interdisciplinary collaboration. By taking these steps, Adeolu believes that the country can thrive in a healthy and sustainable way.
