Project Description

Client: Percon -MMCE -Leighton
Location: Kuala Lumpur
Services: Civil & Structural / Electrical & Mechanical
Completion Date: 2001
Project Value: MYR 450 Million

MMSB Consult was appointed as the Civil Structural, Electrical and Mechanical Engineer for the Ampang Kuala Lumpur Elevated Highway which forms the new elevated toll road along an arterial route in Kuala Lumpur.

The scheme includes two dual three lane sections which run on an elevated superstructure for its full 6 km length. The scheme also includes five interchanges with twelve ramp structures and a fourteen lane elevated Toll Plaza. This highly urban nature of the area has forced the route along the river reserve and the alignment was developed and optimised to accommodate the meandering course of the river.

The superstructure of the Elevated Highway was constructed from precast concrete segmental box girders with dry joints, post tensioned with unboned external tendons. The segmental superstructure was erected on a span-by-span basis using overhead erection gantries. Each span was independently supported and subsequently made fully continuous through the installation of second stage prestress.

Detailed Engineering Design services includes highway alignment and junction layouts, elevated structure consisting of segmental box girder and its setting out details, toll plaza and office building, highway lighting, noise barriers, emergency telephone, CCTV and drive information system and tolling facilities. A new 18-bed casting yard was set up to cast the 4,450 segments required.

MMSBs scope includes:

  • Detailed engineering design of civil, structure, electrical & mechanical services
  • Head office technical support during construction
  • Construction supervision
  • Preparation of specification of bills of quantities.
