Pile Cage Stability Evaluation – The Line NEOM
Project Overview
GeoStruXer along with A-squared Studio conducted an independent design review to evaluate the stability of a reinforcement cage during lifting operations. The cage, weighing 16,956 kg with a length of 20 metres and a diameter of 2.3 metres, is intended for use in 2.5-metre-diameter piles. The lifting system, comprising 32 mm diameter circular lifting bands spaced at regular intervals and six hooked chains, was assessed under static and dynamic loading scenarios, including wind forces and weld capacities.
Challenges
Solution Approach
Conducted checks for shear, deformation, and weld capacities under conservative loading scenarios.
Verified weld adequacy using an E35 electrode.
Highlighted critical precautions, such as prohibiting lifting from shear links and ensuring competent welding practices.
Value Engineering & Sustainability
Conducted checks for shear, deformation, and weld capacities under conservative loading scenarios.
Evaluated cage behaviour under wind forces and dynamic effects with a 1.25 enhancement factor.
Verified weld adequacy using an E35 electrode.
Highlighted critical precautions, such as prohibiting lifting from shear links and ensuring competent welding practices

Collaboration
Worked closely with Trevi Arabian Soil Contractors, incorporating bar bending schedules, reinforcement drawings, and client-provided assumptions into the evaluation. Recommendations align with site-specific conditions and client requirements.
