T.Y. Lin International (TYLI) was responsible for the delivery of Civil & Structural Engineering Services for the design of the National University Hospital (NUH) Medical Centre in Singapore. Drawing on TYLI’s expertise with healthcare structures and complex building design, the project team overcame numerous engineering challenges.

The NUH Medical Centre lies adjacent to the existing NUH Hospital and directly above an operating Mass Rapid Transit (MRT) station and tunnels on Singapore’s Circle Line. The facility has a gross floor area of 72,000 square meters and accommodates six linear accelerator bunkers on the 8th floor; operating theaters and diagnostic imaging facilities; four floors of medical suites; the National University Cancer Institute of Singapore; and four decks of integrated parking.

Careful planning, from the feasibility study through to project implementation, enabled successful delivery of the project, with no disruption to the operation of the MRT or the hospital.

Project Highlights:

  • The project was delivered within an ambitious, 28 month program.
  • The project team overcame and managed a number of challenges associated with the site, including undulating terrain and a varying geological profile, with the rock formation ranging from fully- to highly-weathered.
  • TYLI’s development of a steel truss system, incorporating six sets of double steel transfer trusses located between Levels 12 and 13, allowed for the expansion of the gross floor area by supporting the addition of eight extra floors over the MRT station box.
  • For best hospital planning and operational efficiency, the six linear accelerator bunkers were located on the 8th floor. That made it a key design consideration to ensure the adequacy of the formwork to support the wet concrete required for bunker construction.
  • To eliminate micro-cracking of the bunker structures, the 2.5-meters-thick bunker slabs at Level 8 were cast in seven layers, using ice water and cement replacements for effective control of the peak and differential temperatures.
