LTA ER495 – Roadworks at Upper Serangoon Road between Hillside Drive & Lowland Road
Contract ER495 involved the widening and recambering of live carriageways along Upper Serangoon Road. To minimise the inconvenience caused to the public, the project team has planned the works meticulously, coupling with systematic execution of temporary road diversions.
Besides, innovative products and services were also deployed to speed up the construction process. For examples, semi-rigid pavements were installed at all junctions, temporary road markings were removed using in-house ultra-high pressure (UHP) waterblasting system and etc.
Alongside, the drainage system and other road facilities were duly upgraded with the construction of reinforced concrete drains, box culverts and sumps, building of new retaining structure and erection of new covered linkway.
The relentless safety efforts that the project team have put in place were not left unnoticed with the conferment of Certificate of Merit (Minor Category) during LTA’s Annual Safety Award Convention 2017.
