Executive Summary

This report will discuss the infrastructure management of the Storm Water Management and Road Tunnel (SMART) of Kuala Lumpur, Malaysia. This tunnel was built mainly to cater to the reoccurring flash floods that happened in the area, and to act as an alternate traffic route. It began construction in 2003 and was operational early 2007.

A structure of such magnitude required in-depth designing and precise construction methods to ensure that the structure would be able to fulfill its desired purposes. As such, the structure has indeed proved worthy of being able to not only provide a solution to the flash floods, but also act as an alternate route for traffic heading from and to the city.

An asset management plan is crucial in identifying important aspects of the structure. These include the current and desired performance of the structure, identifying maintenance issues, highlighting critical risks, analyzing factors as well as providing suggestions and non asset solutions to potential problems and predicaments.

The report will discuss in detail:

- asset management practices
- level of services
- stakeholder analysis
- demand forecasts
- factor sensitivity analysis
- condition monitoring plans
- risk analysis and management

1. Introduction

The Stormwater Management and Road Tunnel or SMART Tunnel is an incorporated infrastructure consists of a storm drainage and road structure in Kuala Lumpur, Malaysia. It is the longest stormwater tunnel in South East Asia and also the second longest in Asia. Besides that, it is a one of its kind dual-purpose tunnel project integrating stormwater and motorway. The main objective of this infrastructure is to solve flash floods problems in Kuala Lumpur as well as to reduce traffic jams along Sungai Besi Road and Loke Yew flyover at Pudu during rush hour. There are two major components of this infrastructure – stormwater tunnel and motorway tunnel. Other components also include diversion structure, a holding basin, a bypass tunnel, a storage reservoir and the twin box culvert and an outlet structure. The SMART tunnel begins at Berembang Village Lake near Klang River at Ampang and ends at Taman Desa Lake near Kerayong River at Salak South. The tunnel is about 9.7 km long and has an internal diameter of 11.83 m. The total storage capacity for SMART system is 3 million m3. The motorway will consist of a 3 km double deck structure within bypass tunnel with ingress and egress connection links at both ends of the structure. This project is led by the Government of Malaysia through Malaysian Highway Authority (LLM) and the Department of Irrigation and Drainage Malaysia (JPS) and also a company joint venture of Malaysian Mining Corporation Berhad (MMC) and Gamuda Berhad. The cost of construction is about AU$558.44 million. The construction works started on January 2003 and the SMART Tunnel began its operation at the end of June 2007. The tunnel operates on 3 methods – normal conditions, most storms or major storms. Motorway will still be opened to traffic during normal conditions and most storms. During major storms, the motorways will be closed at both ends to traffic using twin water-tight flood control gates and flood waters will be allowed to pass through the tunnel. After 48 hours, the tunnel will be reopened to traffic. For safety purposes, the ventilation or escape shafts are allocated at 1 km intervals in the tunnel which consists of an exhaust and fresh air injector to protect the ventilation system during floods. The fans which are positioned outside of the SMART Tunnel can create a continuous longitudinal flow of air within the tunnel. In addition, this feature will also allow the control of smoke in the event of fire....
