Lakeview Garden Residence — Under-Soil & Substructure

Uttara, Dhaka · Completed 2024

Lakeview Garden Residence — Under-Soil & Substructure — under-soil works construction project completed by Build & Care Development Ltd. in Uttara, Dhaka
2-Level Basement · 7m Deep Dewatering & Earth Retention
Project Overview

What We Delivered

A lakeside plot with a high water table needed a two-level basement seven metres deep. Everything that made the site attractive also made the excavation difficult.

Build & Care designed and executed the full below-ground package: earth retention, staged dewatering, waterproofing and the substructure the residence now stands on.

The Challenge

Groundwater sat barely two metres below grade, and an uncontrolled drawdown risked settlement in the neighbouring plots.

Our Approach

A secant retention wall was combined with staged, monitored dewatering, with instrumentation tracking ground movement at the boundary throughout the dig.

The Outcome

The basement was completed dry, with recorded movement at neighbouring foundations staying inside a third of the allowable limit.

Scope of Work

  • Earth retention design & installation
  • Staged construction dewatering
  • Basement waterproofing & tanking
  • Underground utility & drainage corridors
  • Instrumentation & settlement monitoring
