2. Smart Tunnel Report
Introduction
The site visit is held on the Thursday of 10th of October 2013 which organized by
Puan Mariatul Liza who is our Building Services 1 lecturer. This site trip is about
Stormwater Management and Road Tunnel (SMART) also known as “Smart Tunnel” in
Malaysia which located in Imbi, Kuala Lumpur. After that, Mr. Mohd Mustaffi briefs us
about the SMART tunnel.
First of all, SMART is actually storm drainage and road structure which consist of
two component which helps to solve problem of flash floods in Kuala Lumpur and also
reduce traffic jams along Jalan Sungai Besi and Loke Yew flyover at Pudu during rush
hour. SMART is 9.7km long stormwater bypass tunnel
This consists of two components which is stormwater tunnel and motorway
tunnel. Stormwater tunnel consists of 13.2m (43.3ft) of outer diameter and 9.7km long
which begins at Kampung Berembang Lake near Klang River at Ampang and ends at
Taman Desa Lake near Kerayong River at Salak South. Motorway tunnel consists of
double deck structure with 4km long which route from the Southern Gateway of
KualaLumpur–Seremban Highway, Federal Highway and East-West Link entering the
city centre.
The SMART tunnel works in three modes. The first mode which is under normal
conditions where there is no storm or flood water will be diverted into the system. When
the second mode is activated, flood water in lower channel of motorway tunnel will
divert into the bypass tunnel. In this case the motorway section still open to traffic.
When the third mode is in operation, the motorway will be closed to all traffic. After
making sure that all vehicles have exited the motorway, automated water-tight gates will
be opened to allow flood waters to pass through. The motorway will be reopened to
traffic within 48 hours of closure after the maintenance.
Not only that, SMART tunnel also have additional features that are unique over
and above the features seen in a normal motorway tunnel. Automated flood control
gates are used as water tight gates are installed on either ends of the motorway tunnel
within the stormwater section. Similar single flood control steel gates are installed at
both entrances and exits of the motorway tunnel. Cross passage are used between
decks at 250m intervals which act as emergency exits during emergency. Ventilation
and escape shafts are located at 1km intervals which consist of powerful air ventilators
that will constantly renew the air and maintain the air quality within the motorway. Radio
re-broadcasting services available as can receive radio channel, handphone and other

3. maintenance communication reception without any interference. SCADA monitoring and
surveillance as 212 units of Closed Circuit Television (CCTV), BARCO wall is able to
show 70 CCTV’s screen at one time and automatic detection systems use video image
and laser beams processing to detect unusual events. First responder vehicle (FRV)
which is a custom built fire engine which could shorten mobilization time from a Fire and
Rescue Department. Medical Response Vehicle (MRV) which is a custom built
ambulance which is capable in emergency treatment.
Throughout this visit to SMART tunnel, we gained more knowledge about
stormwater management in Malaysia. We also get to know how a SMART tunnel’s
function in traffic and stormwater management.
