Bridges In Indonesia
Indonesia is an archipelago and tropical country has many
rivers/channels.
Recorded more than 88,000 bridges (1,050 km) including railway
crossing/ FO.
More than 21.371 bridges (404.84 km) located on National roads.

Process to collect data of physical bridges condition that
can be used for programming of bridge works,
maintenance (routine, periodic), rehabilitation,
retrofitting and replacement of the bridge.
Objective
• To convince the function of bridge in a safe condition for
users, besides to keeping investment value of bridge.
• To determine the maintenance action.

Implementation of Bridges in Indonesia are managed using a system called the Bridge Management
System (BMS), which includes the planning / programming, feasibility studies, technical planning,
implementation, operation and maintenance of bridges.
Stages Of Bridge Implementation
Refers to:
- NSPM Techniques
- Bridge Information Systems
- Best Practice Bridge
- Rehabilitation of Bridge Specifications
- Strengthening procedures BridgeUpgrading/Capacity Expansion Activities

WHEN ??
Follow the recommendations
presented in inspection reports
WHO ??
An experienced or licensed professional engineer is qualified
Where to repair and rehabilitate ??
Selective criteria can be applied based on location
and on a priority basis
Which bridges to repair and
rehabilitate first?Those which require
emergency work have a higher priority depending on condition evaluation

WHY ??
Safety, continuity of use & failure prevention.
1) Improve traffic condition
2) Addressing environmental concern
3) Increasing load capacity
4) Correcting deficiencies
5) Providing for possible future widening
6) Minimizing cost
The consideration are :

Structural Health Monitoring
System (SHMS)
• A system which can be used to detect a defect in the
structure with a Non-Destructive Test (NDT).
• This system could maintain the structure, so the
structure’s degradation and defect can be detected
early.

The Importance of SHMS
• Suramadu Bridge has a very complex structure.
• Suramadu is a huge investation.
• Degradation / Structure deterioration needs to be monitored
continuously.
• Manual monitoring activity will cost a lot of time and money.
• Is based on visual bridge inspection
• Requires a lot of time and money
• Provides a high risk to the checker
