Abstract: This paper present structural integrity assessment of the remodelled office building for the National Directorate of Employment (NDE), Abuja. Structural and the architectural drawings were reviewed. Visual inspections, soil investigation, and in-situ concrete testing were carried out. However, to identify structural flaws and the type of reinforcement bar used; structural elements were measured, photographed were taken, Ground Penetrating Radar (GPR) was used to assessed the reinforcement in all the structural elements (columns, beams and slabs). A total station survey of the structure utilizing structural Non- Destructive Test Unmanned Aerial Vehicle (NDTUAV) was used to create the as-built plan for the building. The elevations inside the construction area were surveyed to determine the slope's orientation in order to assess the effects of wetting on the building foundation. There was no indication of structural fatigue on the structural components at the time of the visit. The structural members' in-situ compressive strength tests were satisfactory. The geotechnical investigation yielded the permissible soil carrying capacity between the range of 96.63 kN/m2 to 278.76 kN/m2. The structural members were constructed based on accepted engineering principles and the structural components were found to comply with the design specification. As a result, the structure is safe, reliable, and passed the structural integrity assessment.

Abstract: Soil stabilization is a critical aspect of civil engineering, involving various methods to modify soil properties and enhance its engineering performance for diverse construction projects. The necessity for soil stabilization arises when natural soil conditions cannot support structural loads due to undesirable characteristics. Soil stabilization involves altering soil properties through chemical or physical means to increase bearing capacity, weathering resistance, and permeability while reducing construction costs. Waste management and waste materials play a significant role in soil stabilization techniques by providing sustainable and eco-friendly solutions to improve soil properties and enhance stability. The connection between waste management and soil stabilization lies in the utilization of various waste materials as stabilizing agents. These waste materials can serve as cost-effective alternatives to traditional stabilizers while reducing the environmental impact of construction and civil engineering projects. This research acknowledges the significance of soil stabilization for civil engineering purposes and explores the effectiveness of various materials as soil stabilizers. Different kinds of stabilization techniques like cement, lime, fly ash, chemical, bituminous, thermal, and electrical stabilization, and other recycled waste materials are investigated. This comprehensive review serves as a valuable resource for civil engineers, researchers, and practitioners seeking a holistic understanding of soil stabilization techniques. As infrastructure demands continue to grow, adopting and advancing soil stabilization techniques becomes imperative for ensuring safe, resilient, and cost-effective construction practices in the face of changing geotechnical challenges. The insights gained from this review will aid in making informed decisions for successful soil stabilization in various civil engineering projects, ensuring the safety, stability, and resilience of infrastructure developments in an ever-changing environment.
