Case Study: How S.H. Foundation is Securing a 4-Basement Excavation at Rupayan City Uttara

by with No Comment Construction

The Rupayan City Uttara Mexus Market is one of the most ambitious commercial projects currently underway in Dhaka. A key challenge of this project is the construction of four deep basement levels in a bustling urban area. S.H. Foundation & Construction was contracted to engineer and implement the critical excavation support system.

The Challenge: Deep Excavation in an Urban Zone Excavating for a four-level basement requires removing a massive volume of earth. This presents significant risks, including soil collapse, damage to adjacent properties, and ensuring the safety of hundreds of workers. A robust, meticulously engineered shoring solution was not just recommended; it was essential.

The S.H. Foundation Solution: A 3-Layer Joist Bracing System Our engineering team designed a comprehensive 3-layer joist bracing system to secure the site. This involves:

  • Installing an initial earth retaining wall using sheet piles.
  • Constructing a massive internal support frame using approximately 1800 tons of steel joists.
  • Carefully planned installation of three horizontal layers of bracing as the excavation goes deeper, ensuring continuous stability.

The Result: Safety and Progress Thanks to this robust engineering solution, the deep excavation at Rupayan City Uttara is proceeding safely and according to schedule. This project stands as a testament to S.H. Foundation’s capability to handle the most demanding deep excavation and shoring challenges in Bangladesh.

Choosing the Right Foundation: A Guide for Construction Projects in Bangladesh

by with No Comment Construction

The success of any major construction project in Bangladesh begins long before the first wall is raised; it starts deep in the ground. The choice of foundation is the single most critical decision, ensuring the structure’s long-term stability and safety, especially given the country’s diverse soil conditions. This guide will help project managers and developers understand the key differences between common piling methods we utilize.

1. Precast Piling: The Power of Consistency and Speed Precast piles are high-strength concrete columns manufactured off-site under strict quality control. They are then transported to the location and driven into the ground with powerful hydraulic machinery.

  • Best For: Large-scale projects with consistent soil conditions where speed is essential.
  • Advantages: High quality control, rapid installation, and immediate load-bearing capacity.
  • Real-World Example: For the landmark Bangabandhu Novotheatre in Barisal, a project requiring a solid foundation for a major public structure, approximately 2,000 precast piles were driven to ensure stability and longevity.

2. Joist Bracing: Securing Deep Excavations When a project requires deep basements for parking or other facilities, securing the surrounding earth is a critical safety challenge. This is where a shoring solution like joist bracing becomes essential.

  • Best For: Urban projects with multi-level basements, such as commercial towers or hospitals.
  • Advantages: Prevents excavation collapse, ensures worker safety, and allows for efficient construction below ground level.
  • Real-World Example: At the Popular Hospital Bhaban in Rajshahi, we installed a 2-layer joist bracing system to safely excavate for three basement levels, proving essential for construction in a dense urban environment.

Conclusion: Partner with an Expert Choosing the right foundation is a complex engineering decision. By partnering with an experienced team like S.H. Foundation & Construction, you ensure your project is built on a base of expertise and safety from day one.
