Kheng Cheng School

DP Engineers had the privilege to work with Kheng Cheng School in its upgrading programme (addition & alteration works) to give the existing campus a face-lift and add an indoor sports hall (ISH) into the premise. The ISH building at the back of the school is four storeys high and houses a multi-purpose area, a sports hall and classrooms. The main structural systems adopted for the ISH are post-tensioned reinforced concrete (RC) beams and slabs, precast staircase and a double-volume steel roof truss at its apex. Pre-cast elements and the steel truss roof helped to increase construction speed and productivity on site during the project.

Post-tensioning is a method of reinforcing concrete or other materials with high-strength steel strands or bars, typically referred to as tendons. In building construction, this method allows longer clear spans, thinner slabs, fewer beams and more slender, dramatic elements. Thinner and smaller elements mean less concrete is required, which in turn reduces the embodied energy for a structure thus, creating a sustainable structural solution.
