Bhagwati Machinery stands at the forefront as a Top down construction service provider, employing innovative construction methodologies that significantly enhance the efficiency and safety of building projects. Our approach involves the strategic installation of vertical load-bearing elements and a retaining system from the ground level using advanced piling and retaining wall techniques.
Bhagwati Machinery is succeeded to provide Top Down construction services. Wherein upper section is built prior to the lower. It seems strange but with our extreme efforts we have succeeded to achieve this technique. This is the risky method but our skilled people could successfully achieved this goal which is also called reverse approach.
Process Overview:
- Initial Construction Phase: We commence by installing piles and retaining walls directly from the natural ground level, followed by casting an in-situ lid, which serves as the future suspended ground floor covering the entire area slated for excavation.
- Simultaneous Excavation and Superstructure Construction: Once the lid is in place, excavation proceeds underneath to the required depth while the superstructure is built simultaneously above ground. This method not only accelerates the construction timeline but also reduces the costs associated with site mobilization and extends the potential for earlier tenancy due to faster project completion.
Advantages of Top Down Basement Construction
- Material and Cost Efficiency Our innovative retaining wall designs require less concrete and steel reinforcement, responding adeptly to the rising costs of construction materials. This reduction in resource use not only offers an environmental benefit by lowering embodied energy but also cuts overall project expenses.
- Reduced Environmental Impact By eliminating conventional sheet piling and extensive propping and anchoring, our construction approach minimizes noise, dust, and vibrations. This method proves exceptionally safe when working near neighbouring properties, avoiding the need for extensive regulatory compliance.
- Optimized Design and Documentation All substructure components are meticulously designed and documented in-house, ensuring seamless integration and optimal material use. We eliminate common design gaps typically left for specialists, ensuring every critical element is engineered for the best possible outcome.
- Noteworthy Precision Our precision in construction has led to us gaining recognition and accolades, thus showcasing our capability to work within stringent tolerances. We have undertaken various projects and have successfully completed them without inducing any kind of damage.
Ground Anchor Systems Benefits in Construction
- Enhanced Safety: Our ground anchors provide essential lateral stability, significantly reducing the risk of collapse by stabilizing diaphragm walls against external forces.
- Cost and Time Efficiency: The use of ground anchors can diminish the necessity for traditional supports like struts and braces, reducing both the material costs and construction timelines.
- Versatile Wall Configurations: Ground anchor systems accommodate a diverse range of diaphragm wall designs, from straight to curved or stepped configurations, offering flexibility in construction planning.
Integration with Diaphragm Wall Construction
To further ensure the integrity and longevity of diaphragm walls, we incorporate PVC water stoppers in the joints. These water stoppers enhance the waterproofing capabilities of the walls, preventing water leakage and seepage while protecting the concrete from potential corrosion and cracking.
Types of Structures Suited for Top Down Basement Construction
Top down construction is ideally suited for structures requiring deep basements, such as high-rise buildings, parking garages, subway stations, and underpasses. This method is particularly effective in urban environments where space constraints or soil movement must be minimized, delivering robust solutions even when traditional tieback or anchor installations are not feasible.
At Bhagwati Machinery, our commitment as a Top down construction contractor reflects our dedication to innovative, safe, and cost-effective construction solutions tailored to meet the dynamic needs of modern urban landscapes.
