Elevating Construction: The Blueprint to Success with Precast Multi-Storey Buildings 

Elevating Construction: The Blueprint to Success with Precast Multi-Storey Buildings 

Nestled at the heart of the urban sprawl, this high-rise residential development epitomizes excellence in modern construction. Comprising of 272 apartments spanning two towers, the project employs a precast concrete vertical structure, post-tensioned concrete slab, and a metal decking basement slab structure.

“Maximizing Precast Construction: A High-Rise Residential Case Study”

272 Apartments, 2 Towers – Elevating Construction Standards to New Heights


A newly built residence, a dream home for its inhabitants, became the focal point of a daunting challenge. The builder, proud of his craftsmanship, found himself entangled in the complex webs of construction litigation. With the structural integrity of the home in question and no previous testimonies, drawings, certifications, or inspections to fall back on, the situation was dire. 


The Challenges We Faced:

  • Podium's Expanse: A sprawling 2,800 sqm podium floor presented a massive area to manage and monitor effectively.
  • Budget Constraints: The ambitious project faced tight financial constraints, demanding optimal resource allocation.
  • Dimensional Dilemmas: Low headroom spaces posed construction and design complications.
  • Building's Jigsaw: Multiple building joints, coupled with irregular tower level floor plates, required a meticulous approach to integration and alignment.
  • Structural Complexities: Balancing long-span post-tensioned slabs, cast insitu columns, precast load-bearing walls, and metal decking formwork was no small feat.
  • Stakeholder's Orchestra: A joint venture with numerous stakeholders, consultants, and client-side PMs called for harmonious coordination and seamless communication.
  • Detailing Devil: The intricacies of precast concrete, post-tensioned slab, building, and construction joints demanded precision and expertise in detailing.

Palantir's Solution Implementation: 

  • Early Engagement: Initiated the structural design process at the concept stage, ensuring foundational decisions were proactive and informed.
  • Sub-contractor Synergy: By involving subcontractors from the get-go, we ensured a convergence of brainstorming and cost-effective ideas.
  • Digital Blueprint: The BIM Digital twin was employed, ensuring accurate documentation and a structural model that responded to real-time changes.
  • Sequenced Success: Our designs prioritized the construction sequence, focusing on minimizing risks throughout the project's lifecycle.
  • Unified Detailing: Streamlined and standardized construction detailing was introduced, simplifying methodological complexities.
  • Data-Driven Decisions: Integrated material tonnage and quantity take-off sheets within the BIM model to stay on top of resource management.
  • Responsive Design: Adapted design strategies in response to site feedback, ensuring flexibility and relevance.
  • Quality Assurance: Prioritized the selection of structural products with a proven track record, ensuring durability and performance.

Impactful Outcomes: 

  • Budget Clarity: Early budget determination meant no surprises down the line, fostering better financial planning.
  • Pinpoint Accuracy: Aimed for a razor-sharp accuracy, achieving a final structural material quantity variance of just 5% from design to reality.
  • Negotiation Leverage: Our data-driven approach empowered the client, placing them in a position of strength during subcontractor negotiations.

Important Takeaways:

  • Proactive Designing: Beginning the design process earlier can pave the way for strategic decision-making, especially when choosing structural types.
  • Supplier Sync: Open dialogues with suppliers about material wastage are crucial. It equips subcontractors to quote more precisely, mitigating end-project surprises.
  • Steady Communication: Weekly touchpoints with clients ensure everyone is on the same page. This proactive approach accelerated design updates and troubleshooting.


Navigating the complex terrains of high-rise residential development requires foresight, precision, and collaboration. By blending traditional methods with advanced technological tools and emphasizing early stakeholder engagement, we not only met but exceeded project objectives. Here's to building the future, together, one structure at a time.
