Healthcare facilities require reliable structural performance, efficient construction timelines, and high-quality workmanship. In Singapore, where construction schedules are tightly managed and space is limited, precast construction has increasingly become a preferred method for delivering modern public infrastructure.
For the recent Jalan Damai Polyclinic development, the project team adopted a hybrid precast column connection system supplied by Leviat. The solution combines the Moment MPS‑T Precast Shoe with the Moment Grout Coupler, enabling efficient and robust connections between precast columns and the supporting structure.
This project builds on Leviat’s trusted track record in healthcare infrastructure throughout Singapore, including earlier applications in the Jurong Polyclinic, National Skin Centre and Woodlands Health Campus.
Technology in Action
The Moment Hybrid Precast Connection integrates two engineered components for a reliable and efficient structural system:
1. Moment MPS‑T Precast Shoe
– Cast into the precast column during fabrication
– Simple bolted connection with immediate load transfer
– Designed to support temporary construction loads, allowing cranes to be released immediately after tightening
2. Moment Grout Coupler
– Cast into the precast column
– Ensures reinforcing bars can be securely connected with high‑strength grout
– Designed to carry permanent structural loads after grouting
During erection, precast columns are positioned so the embedded shoes and couplers align precisely with starter bars from the supporting structure. Once aligned, the couplers are grouted to complete the structural connection.
This hybrid configuration provides a controlled and efficient column‑to‑column and column‑to‑foundation connection, ensuring structural continuity and reliable load transfer once the grout cures.
Why the Moment Hybrid Precast Connection Was Chosen
1. Integrated Connection Solution
By supplying both the precast shoe and grout coupler, Leviat provided a coordinated system with full component compatibility. Leviat, as a single supplier of the complete connection system, is fully responsible for the design, compatibility, and site training, avoiding complications that may arise from multiple third‑party components.
2. Faster Precast Installation
Precast columns can be installed more rapidly, helping shorten the overall construction schedule. Because the precast shoes are immediately load‑bearing, the crane can be released right after the anchor bolts are tightened. This allows the next column to be lifted even before grouting begins. Leviat also recommends mass grouting, where the entire system can be grouted in one operation—further streamlining installation
3. Reliable Structural Performance
The engineered system effectively transfers axial, moment, and shear forces. With precast shoes handling temporary loads and grout couplers handling permanent loads, the hybrid system enables propless installation while maintaining full moment continuity.
4. Collaborative Design Development
Connection details and calculations were jointly developed with engineering consultants to meet project requirements.
Project Impact
The adoption of the Moment Hybrid Precast Connection System provided the following benefits:
– Improved construction efficiency through faster precast installation
– Streamlined detailing using an integrated engineered solution
– High‑quality structural performance meeting stringent healthcare standards
– Strong collaboration between supplier, contractor, consultant and precaster
