Abstract
Purpose Groundwater levels (GWL) are rising in many cities in the world. The purpose of this study is to present the multi‐faceted approach adopted for examining the impact of a 3 m rise in GWL on the durability, stability and strength of the structural components of a building complex with 40,000 m 2 basement. It also reports on the retrofit measures adopted to remedy the situation. Design/methodology/approach The overall stability of the building complex was examined for the revised loading conditions as well as the need to strengthen the structurally deficient components to satisfy owner's requirement of a dry and operational basement without the dewatering operation. Structural conditions of the basement walls and a slab of the building complex were assessed based on code guidelines, visual observations, site investigations, analytical finite element model (FEM) studies and sound engineering judgement. Findings About 25 percent of the existing basement slab was found to be structrally deficient to resist the applied hydrostatic load. A number of articulation and construction details were also found to be inadequate. Various options for retrofit for the deficient structural components and articulation details were examined and design details were presented for a cost‐effective solution. Research limitations/implications The presented methodology is general and can be adopted for similar situations. However, the presented solutions and conclusions are specific to the problem presented herein and modifications will be required for adoption to other situations. Practical implications Practising engineers are made aware of the problem of rising GWL for underground structures. Practical information is presented for practising engineers to solve the problem of water leakage in a large basement. Originality/value This paper presents an integrated approach for addressing the structural implications of rising groundwater level in an operational basement of a large building complex.

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
