Foundation Remediation with InSAR – Al-Awali School Bahrain
Project Overview
On 12th July 2024, GeoStruXer was commissioned by MSCEB to design a foundation rectification system for Al-Awali National School in Bahrain, following severe cracking and deformation due to foundation issues. Using advanced 3D soil–structure interaction (SSI) analysis, GeoStruXer evaluated the foundation under various scenarios, identifying significant deficiencies in the footings. Two repair options were proposed: micropile underpinning and geopolymer grouting. The study provided key insights into the foundation’s performance and recommended strategies, enabling informed decision-making.The project aimed to harness existing soil conditions while ensuring enhanced structural performance and sustainability.
Challenges
Solution Approach
Advanced SSI Analysis
3D FEA integrated superstructure, foundation, and ground behaviour, considering staged construction and non-linear soil properties.
Model Calibration
Improved accuracy by calibrating soil models with field test data.
Coupled Models
Geotechnical deformation data informed structural force redistribution for a holistic design.
Value Engineering & Sustainability
Precision
Accurate assessments of load transfer and foundation behaviour under real-world conditions.
Cost-Effectiveness
Micropiling avoided extensive foundation replacement, saving time and money.
Alternative Solutions
Geopolymer grouting offered a minimally invasive, flexible option for rectification.
