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.

Bridge Inspection





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

- 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 :





WHAT COMPONENT ??

NEED GREATEST ATTENTION

Deck

Expantion joint

Bearing

NEED ATTENTION

SUBSTRUCTURE

constant wearing surface

erosion or earthquakes

Girder RIVER TRAINING WATERWAYS





1) Field Inspection & structural health monitoring

2) Preparing an inspection report

3) Computing condition rating

4) Analysis & Load Rating

5) Preparing the Rehabilitation report

6) Implementing diagnostic design procedures

7) Selecting method of repair, reftrofit, rehabilitation or replacement

8) Preparing contract document

HOW ??





1) Inventory

Inspection

Type of bridge inspection

Inspection should be done

for a life time of the bridge.

2) Routine

SHMS for LONG and COMPLEX BRIDGES





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
