CREDAI Karnataka Recommends Double Verification of Soil Reports After Bengaluru Tower Tilt Incident

The recent apartment tower tilt incident in Bengaluru has triggered renewed discussions on construction quality and geotechnical investigations, prompting the Confederation of Real Estate Developers’ Associations of India (CREDAI) Karnataka to recommend an additional layer of verification for soil investigation reports before foundation work begins.

The industry body has decided to include the recommendation as a suggested best practice in its developers’ handbook. Although the measure will not be mandatory, member developers will be encouraged to obtain an independent review of geotechnical investigation reports before finalising foundation designs. The objective is to minimise the risk of errors in soil assessment, which forms the basis for structural engineering and foundation planning.

The move follows the incident involving an 18-storey apartment tower at the SNN Raj Etternia project near Kudlu in Bengaluru. The building reportedly tilted after discrepancies were identified in the original geotechnical investigation report. The developer has since decided to demolish and reconstruct the affected 49-unit tower after a fresh investigation highlighted inconsistencies in the soil assessment, while maintaining that the remaining towers in the project are structurally safe.

CREDAI Karnataka said the recommendation reflects the industry’s commitment to strengthening quality assurance rather than introducing new regulations. The developers’ handbook is periodically updated based on practical industry experience, emerging construction challenges and evolving engineering practices. The latest recommendation is intended to encourage greater technical scrutiny at the pre-construction stage, particularly for high-rise developments.

Industry experts believe that independent verification of soil reports can significantly reduce structural risks. Bengaluru’s varying soil profile makes geotechnical investigations particularly important, with conditions often differing even within short distances. Accurate soil data plays a critical role in determining foundation design, structural loading and long-term building stability.

Developers have also stressed that existing engineering guidelines remain adequate when implemented effectively. Along with reliable soil investigations, they emphasise the importance of continuous site supervision, quality construction materials, engineering-based structural systems and strict quality control throughout the construction process.

The latest advisory is expected to encourage developers across Karnataka to strengthen due diligence during the early stages of project planning while reinforcing confidence among homebuyers in the quality and safety of residential developments.
