1. INTRODUCTION

  1.1 GENERAL

  Bridges are important links on the road network and represent a large investment. Indonesia has approximately 25,000 bridges and other crossings on National and Provincial roads, and more than 60,000 on local and urban roads. Sound management of these bridges and the optimum use of funds for their maintenance, repair and replacement is essential for the development and sustainability of a viable transportation and communication infrastructure in Indonesia.

  The Bridge Management System (BMS) supports the Government's policies for National Development and Decentralization. The BMS enables planning to be carried out in a systematic way and provides uniform procedures for all bridge activities at National and Provincial level.

  It is important that all planning is based on reliable data and that uniform procedures are used for the preparation of bridge work programs. It is also important that implementation and monitoring of bridge works is carried out to a high standard, incorporating acceptable design and construction techniques to ensure maximum life from the bridges.

  In order to satisfy these requirements, the Directorate General of Highways (DGH) has developed the Bridge Management System which enables it to plan, execute and monitor all bridge activities within an overall policy. In particular, with a large. number of bridges having been replaced since the 1970's, Indonesia is now increasing funding for Maintenance and Rehabilitation of existing bridges as Bridge Replacement needs reduce. The BMS enables DGH to identify and prepare treatments needed to keep bridges functioning, and to rank them in a priority order for Works programming. The BMS developed to date is for bridges located on-National and Provincial (Interurban) roads and is called the Interurban BMS (IBMS).

  This Manual describes the overall procedures to be followed in the execution of the Bridge Management System in Indonesia. The BMS is applied to all crossings on National and Provincial roads which are longer than

  1.2 OBJECTIVE OF MANUAL

  The objective of the General Procedures Manual is to provide simple general procedures for the operation of the BMS in Indonesia. The Manual provides an overview of the BMS and refers to all other BMS Manuals for detailed operational procedures. The Manual provides quidance for the operation of the BMS as a whole.

  1.3 HOW TO USE THIS MANUAL

  The Manual should be read as a whole in order for the reader to gain an overall understanding of the BMS. The description of the General Procedures in the Manual follows the two charts in Figures 1 and 2 which show the BMS components (Figure 1) and the BMS activities (Figure 2) in the form of flowcharts.

  1.4 SCOPE OF MANUAL The Manual consist of four Parts.

  Part 1 is the Introduction to the Manual. Part 2 gives an overview of the BMS. Part 3 is the main text of the Manual, setting out the General Procedures for the implementation of all BMS activities. Part 4 contains Appendices which give relevant information that is not part of the Procedures. The Appendices contain: Appendix 1 List of BMS Manuals Appendix 2 An outline of the organisation of DGH and DPU in Provinces as it relates to bridgeworks Appendix 3 Duty Statements for BMS personnel in Provinces.

  1.5 WHO SHOULD USE THE MANUAL

  The Manual should be used by all personnel involved in BMS activities so that they can obtain a clear understanding of the operation of the BMS and how the activity on which they are engaged fits into the overall System. The Manual should be read by all officials within DGH and Bina Marga in Provinces who are involved with Roads and Bridge planning, implementation and maintenance.

  Please note that all references to BMS in this Manual are for the Interurban BMS (IBMS). If more detailed information is required on the techincal aspects of any activity, reference should be made to the Manuals which have been prepared for each component of the BMS. A list of Manuals produced for the BMS is included in Appendix 1.

2. OVERVIEW OF BMS

2.1 OBJECTIVE OF BMS

  The overall objective of the BMS is to provide DGH and Bina Marga in Provinces with a tool to: x support National Development and Land Communications through a safe and functional network of bridges, and to x optimize the use of funds available for bridge works. The BMS provides the facility for: x inventory recording of all bridges:

• The BMS includes a Management Information System (IBMS-MIS), and a database of all bridges on National and Provincial roads in Indonesia which provide easy access to information on any or all bridges.

  x condition, traffic and load capacity rating:

• all bridges are inspected and assessed for Condition, Traffic Capacity and Load Carrying Capacity.

  x identification of bridges for treatment:

• bridges which are in poor condition, too narrow or not strong enough to carry normal traffic are screened out and alternative treatment strategies are prepared for repair, strengthening, widening, duplication or replacement. The most economic treatment can be determined.

  x priority, ranking of bridge works:

• bridges proposed for treatment are ranked in order of economic priority to ensure that bridges are treated in a sensible order.

  x optimum allocation of funds

• by determining the optimum (most economic) treatment strategy for a bridge, and ranking bridges in priority order, it is ensured that funds are spent in the best way.

  x standard procedures for implementation of all bridge works.

• standard procedures are available for each major bridge activity from site investigation to implementation and maintenance. The procedures are described in comprehensive technical and procedural Manuals

  2.2 BMS ACTIVITIES A chart of the main BMS Components is shown in Figure 1.

Figure 1

A brief description of each of these components is given in the following sub-sections.

  2.2.1 Policy Framework

  The Policy Framework is established by DGH at the start of the planning period, and includes policies on bridge condition standards, road-width standards, strategic links, link priorities, load capacities and so on.

  2.2.2 Inspections There are four types of bridge inspections in the BMS for the collection of bridge data. Inventory Inspections

  These register the bridges in the database and record administrative, geometric, material, and general condition data.

  Detailed Inspections

  These are carried out at intervals of five years maximum to assess the detailed condition of bridges and their elements. There is a hierarchy of levels for elements in the bridge, to facilitate inspection, and reporting is carried out at the highest level possible. The condition of the bridges and elements is recorded on a scale of zero to five, with a rating of zero for bridges or elements in 'as-new' condition and a rating of five for those that are no longer serviceable. The Condition Mark is derived by a series of objective questions developed originally for the Danish Bridge Maintenance Management System and which was modified for Indonesian conditions. This procedure helps to remove subjectiveness from the derivation of the Condition Mark.

  A Detailed Inspection is also carried out at the conclusion of all major bridge work, to gather updated data. During a Detailed Inspection, the Bridge Inspector checks the Inventory Data and he can make recommendations for treatments and for Special Inspections.

  Routine Inspections

  These are performed annually to check that Routine Maintenance is being carried out effectively and to discover any unreported circumstances which may require Emergency Action.

  Special Inspections

  Special Inspections may be required as a result of the findings of a Detailed Inspection. A Special Inspection may also be needed as part of data verification prior to programming major works determined from the Screening process in the IBMS-MIS.

  .

  A Special Inspection is a detailed investigation into defects and material properties of specific elements, such as core testing-of concrete. A Special Inspection can also be carried out to supplement the Detailed Inspection in cases where the Bridge Inspector did not have the necessary equipment to complete the inspection (eg. underwater inspection), and for periodic monitoring of specific elements of a bridge.

  2.2.3 Emergency Action

  Emergency Action is taken when the condition of the bridge is unsafe for vehicle or pedestrian traffic, and when a bridge is in immediate danger of collapse. This action must be given priority if it is determined that the bridge is at risk and must be kept functioning. Action taken can include minor or major repairs, rehabilitation or replacement.

  2.2.4 Load Rating

  Load Rating is a measure of the load carrying capacity of the bridge measured against a Standard Truck for the route on which the bridge is located. (Currently, the Load Rating Module in the IBMS-MIS is unavailable. However, procedures are described in the Bridge Design Code).

  2.2.5 Management Information System

  The IBMS-MIS forms part of DGH's overall Management Information System (BM MIS). The

  IBMS-MIS contains the Bridge Database and a suite of computer programs which allow: x entry and retrieval of data x preparation of standard reports on bridges x querying the database for any combination of information x Screening, Ranking and preparation of Treatment Programs x preparation of Annual and Five Year Plans x determination of the most economical treatment for each bridge. The IBMS-MIS is integrated with the Road Database in the Interurban Road Management System (IRMS).

  2.2.6 Bridge Database

  All available bridge data is stored in a Bridge Database held in each Province and in DGH in Jakarta. The Bridge Database consists of:

• a computerised Bridge Database, and
• manual bridge files, containing data which cannot be entered onto the computer, such as the original inspection forms, photographs, drawings etc,.

  2.2.7 Planning and Programming

  Planning and Programming involves the preparation of Programs of Work for Replacement, new Bridges, Rehabilitation and Maintenance. The BMS enables preparation of Programs to be carried out in a systematic way by utilizing the IBMS-MIS as a tool for screening, economic evaluation, ranking and budgeting.

  2.2.8 Bridge Investigation and Design

  After bridge programs are finalized, site investigation, site location and preliminary design are carried out before finalizing the design for the bridge works. Bridge Investigation includes: x reconnaissance surveys x topographic surveys x soil investigations x hydrologic surveys. Following these investigations, detailed design and preparation of tender documents is carried out. The BMS includes rules and procedures for Bridge Design, and Standard Specifications for Bridge Construction and Rehabilitation.

  2.2.9 Bridge Materials

  The BMS includes procedures for the management of the major bridge materials storage yards and for the allocation of bridge spans and standard bridge components which are supplied under various Contracts.

  2.2.10 Construction

  The BMS includes standard procedures for supervision of bridge construction and a Manual describing various techniques used in bridge construction..

  2.2.11 Maintenance and Rehabilitation

  Maintenance and Rehabilitation of existing bridges is needed to keep them functioning properly and to prevent bridge collapse. The BMS includes procedures for Maintenance and Rehabilitation of bridges.

  2.2.12 Monitoring

  Bridge construction works are monitored and data is entered into the IBMS-MIS so that at any time up-to-date data is stored in the Bridge Database.

3. GENERAL PROCEDURES OF THE BMS

  This Section describes the General Procedures for operation of the BMS, including an overview of the System so that the reader will understand the relationships between activities, timing, and responsibilities. A General Flowchart is shown in Figure 2. The Flowchart is based on activities rather than components. All bridges are considered as part of this flow and will undergo one type of bridge work each year. The description of the procedures follows the flowchart, so that the reader can easily see where the activity is located in the BMS cycle.

  In order to identify general responsibilities for BMS operation, a schedule of activities and responsibilities is shown in Figure 3. This shows the activities referred to in the Flowchart, together with the organisation responsible and the recommended timing for carrying out the activity. In order to simplify the chart, sub-activities, particularly for the budgeting process (preparation of DUP, Satuan III, DIP etc) are not included. These procedures are documented in other DGH and BMS Manuals.

3.1 POLICY FRAMEWORK

  The Policy Framework establishes the Standards under which the BMS operates. It specifies acceptable criteria for relevant parameters in the BMS as follows: x discount rate for economic analysis x load capacities on each route x link. priorities x acceptable bridge condition level x bridge and road width standards x responsibilities for design etc,. At 1992 the Standards are as follows: x discount rate 15% x load capacity - 10 tonne axle on Strategic Routes

• 8 tonne axle on Non-Strategic Routes x link priorities -

  1 National Arterial

• 2 National Collector and Provincial Arterial -

  3 Provincial Collector x acceptable Bridge Condition Mark 2 or better, ie. 0, 1, 2 x bridge and road width standards AADT Minimum Bridge/road width (metres)

Figure 4 - Overview of Bridge Inspections

  INSPECTION SPECIAL

  

Inventory Inspections were carried out at the start of the BMS to record bridges in the BMS

  with the following data: x Administrative data x Geometric data x Material data x

  General Condition Data for major components. Inventory Inspections are also carried out as part of a Detailed Inspection after major work is performed on a bridge, to update the, general data.

  After all bridges have been registered, Inventory Inspections are only required after major bridge work, ie replacement, widening, strengthening or duplication. This Inspection should form part of the final inspection of the bridge work and be covered by the budget for the Supervision of the construction of the bridge.

  

Routine Inspections are carried out annually on every bridge to check that Routine

  Maintenance is being carried out and to report any Emergency Action needed, particularly with respect to the waterway.

  

Detailed Inspections are carried out on all bridges at least once every five years. Detailed

  Inspections are normally not carried out on small culverts, wet crossings and bridges less than six metres in length. The Detailed Inspection data is used to Screen and Rank bridges for priority for treatment. (At the start of the BMS, Detailed Inspections were conducted on bridges with Condition Mark of 2 or higher, so that bridges which were in need of immediate treatment were inspected). Detailed Inspections (including an Inventory Data update), are also carried out after major work, so that the Database is updated with the correct data.

3.2.2 Personnel

  Inventory Inspections are now carried out by Provincial Bridge Inspectors when doing a Detailed Inspection at the completion of major work on bridges. Detailed Inspections are carried out by Provincial Bridge Inspectors from the Dinas PU Bina Marga or Sub Dinas Bina Marga, under the direction of the BMS Supervisor. Routine Inspections are generally carried out by Cabang Inspectors from the Cabang Dinas Bina Marga office, under the direction of the BMS Supervisor and Provincial Inspectors.

  3.2.3 Planning and Budgeting for Bridge Inspections

  Bridge Inspections must be planned and budget must be allocated. The budget for Inspections is to be allocated from APBN and IPJP through the P3TNas for inspections of bridges on National Roads, and from P'TProp for bridges on Provincial Roads.

  3.2.4 Detailed and Routine Inspections

  In September each year the BMS Supervisor should prepare a list of bridges which require a Detailed or Routine Inspection in the following year. These lists are prepared on the IBMS-MIS through the 'Inspection Program' module.

  The BMS Supervisor must estimate the cost of the inspections taking into account: x Transport costs

  Vehicle operation and maintenance -

• Ferry costs
• Air fares x Inspection Costs - Accommodation - Allowances.

  x Hardware Costs

• Equipment cost

  Printing of forms - File and film processing - Replacement/repair of standard equipment - x

  Data validation and entry. In planning for Inspections, the BMS Supervisor should allow 3 - 4 bridges per day to be inspected for Detailed Inspections, and 10-20 bridges per day for Routine Inspections.

  In general, about 20-25% of the bridges in each Province should undergo a Detailed Inspection each year, except wet crossings, culverts and bridges undergoing work or which are programmed for work in the following year. All other bridges (except those undergoing' work or programmed for work in the following year), should have a Routine Inspection each year.

  Note: At present BIPRAN coordinates the preparation and execution of the Detailed Inspections until the activity becomes fully institutionalised within DPUP.

  3.2.5 Execution of Inspections All Inspections are carried out in accordance with the BMS Bridge Inspection Manual.

3.2.6 Reporting, Data Entry and Data Audit

  All Bridge Inspection Reports must be submitted to the BMS Supervisor, who will arrange for entry of the data into the IBMS-MIS. In each Province, there is a holding file for Bridge Inspection Data - the Bridge Inspection

  

Holding File. The Inspection Reports are kept in this file until they are checked and entered to

the IBMS-MIS.

  The data should be audited prior to entry into IBMS-MIS, because all subsequent activities are dependent on its accuracy. The BMS Supervisor must ensure that the Inspection Data is entered into the computer within 14 days after the Inspection is carried out. After the data is entered to the IBMS-MIS, the BMS Supervisor must file the Inspection Reports, together with photographs and negatives, in the Bridge Data File for the particular bridge. Routine "Inspection Reports from Cabang Bina Marga should be forwarded each month to the BMS Supervisor. A copy of the Inspection Report, together with a copy of the film negatives and one set of photographs should be sent to the BMS Coordinator in BIPRAN.

3.3 SPECIAL INSPECTIONS

3.3.1 General

  Special Inspections can be recommended by the Inspector during a Detailed Inspection when: x the Inspector cannot complete the inspection because of difficulty of access (such as under-decks or underwater) x specialist equipment is required to investigate suspected defects, such as for core testing of concrete x monitoring of specific elements is require to detect movements which cannot be identified during a single inspection.

  There are three types of Special Inspections: x

  Supplementary Inspection

  Another inspection of elements of the bridge which could not be assessed or inspected during a Detailed Inspection except by using special equipment. Equipment or resources required could incude scaffolding for deck inspections or divers for underwater inspections. x

  Material Inspection

  An inspection and evaluation of defects and material properties of specific elements which cannot be visually inspected or which require specialist investigation. Example are concrete testing and assessment of scour problems and treatments. x

  Monitoring Inspection

  Monitoring of the condition, (usually the geometry) of specific elements of a bridge. Special equipment for testing or measurement of level is normally required.

3.3.2 Personnel

  Special Inspections are carried out by Engineers with expertise in the particular type of Special Inspection required. For example, investigation of scour at a bridge should be carried out by experts from PUSLITBANG AIR. Material Investigation should be carried out by Engineers from PUSLITBANG JALAN. * In some cases, Provinces have the necessary equipment and personnel in Provincial laboratories in the KANWIL. The advice of personnnel from the Sub-Directorate of Bridge Design in BIPRAN should be sought in the first instance.

  3.4 LOAD RATING OF BRIDGES

  Determination of the load carrying capacity of a bridge should be carried out on bridges if rehabilitation is being considered and there is doubt about the load carrying capacity of the bridge. It is not necessary to load-rate bridges which are to be replaced or bridges which are in good condition (unless there is doubt about the load capacity).

  Load Rating is carried out in accordance with procedures in the Bridge Design Code. Where there is doubt about the load capacity of a bridge, the Chief of the Bridge Design Sub- Directorate in BIPRAN should be advised, and he will take the necessary action.

  3.5 EMERGENCY ACTION

  If an Inspector has recommended Emergency Action, it should be reported by the Provincial Bridge Inspector or Cabang Inspector directly to the BMS Supervisor, who will take the appropriate action.

  Bridges requiring Emergency Action must be given high priority. The BMS Supervisor must immediately report to the Chief of Planning Section all bridges requiring Emergency Action and they should discuss the Report with the Inspector and determine the action to be taken. Depending on the circumstances, an immediate site visit should be made to ascertain the nature of problem and the rectification needed.

  A decision must be made as to whether the bridge requires immediate repair or whether the work can be deferred until the next Rehabilitation Project. The IBMS-MIS includes the Emergency Action Report No. IBMS-AR 1 which lists all bridges requiring Emergency Action at any time. This Report should be checked and the Bridge Data updated after action has been taken. If emergency funding is required, the Province should apply for allocation of 'Bencana Alam' from DGH.

3.6 IBMS-MIS AND BRIDGE DATABASE

3.6.1 General

  The IBMS Management Information System (IBMS MIS) includes: x the Bridge Database x the computer programs for Data Entry, data manipulation and analysis, Standard Reporting, Monitoring and querying of the Database.

  The IBMS-MIS is a tool which Bridge planners can use to perform routine tasks with greater efficiency. The IBMS-MIS is a subsystem of the Bina Marga Management Information System (BM MIS). The Bridge Database must be maintained and updated through Inspection Reports and Monitoring of Bridge Replacement and Rehabilitation Projects.

  In Provinces, the daily operation of the BMS computer is the responsibility of the BMS Supervisor under the direction of the Chief of the Planning Section. The IBMS-MIS and the Bridge Database provide a great variety of useful information. Most information can be retrieved in Standard Reports, but the facility also exists for querying the Database in a general way. Procedures for querying the Database are given in the IBMS-MIS Manual. The daily operation of the BMS includes the following: x reviewing bridge data x preparation of inspection programs x reporting on bridge condition x evaluation of treatment strategies for bridges x reporting on bridges needing Emergency Action x preparation of Indicative Programs of Work x monitoring construction progress. In DGH, the operation of the BMS is the responsibility of the BMS Coordinator in the SubDirectorate of Bridge Design.

  The daily operation of the BMS in DGH includes similar activities to the Provinces. However, operations are more directed' towards data auditing, long-range planning, preparation of (DGH's) Annual Programs and overall management of the System. Guidance and direction on the operation of the BMS is available through the Chief of the Sub Directorate of Bridge Design and the BMS Coordinator.

3.6.2 Interface with IRMS

  The BMS uses data directly from the IRMS. Data is exchanged in BIPRAN through a Local Area Network which connects the two Systems. The IBMS-MIS uses Road Programming Data from the IRMS to establish priorities for Bridge Programs of Work. The following data from the IRMS is used by the BMS: x vehicle operating cost (by vehicle type) x traffic data by link and suffixed link x data reference points x projected traffic growth rates x road conditions x road width x road works programs

  In Provinces, data is exchanged with BIPRAN by monthly basis by floppy disk. The procedures for exchanging data are explained in the IBMS management Information

  System Manual.

3.6.3 Backing-up of Data

  Bridge Data should be backed-up every week by the BMS Supervisor. At the end of each month, a copy of the data must be sent to the BMS Coordinator in BIPRAN for updating of the Central Database. The data disk should be addressed to:

  Koordinator BMS Sub Direktorat Jembatan Direktorat Bina Program Jalan Departemen Pekerjaan Umum Jl Pattimura 20 Kebayoran Baru - Jakarta Selatan

  3.7 SCREENING AND TECHNICAL RANKING Screening is the filtering-out of bridges that require treatment based on current policy.

  Screening can be carried out at any time, and must be carried out in August each year, in preparation of the Annual Program for the following year. The purpose of Screening is to identify bridges with: x poor condition x inadequate traffic capacity x insufficient load capacity. The Screening model in the IBMS-MIS uses the data in the Bridge Database to determine indicative treatments for each bridge. These treatments must be confirmed by the BMS Supervisor or Planning Engineer by a field inspection, before the bridge is committed for major works. The Screened bridges are given a Rating which is a function of the Condition Mark, the importance of the element, the importance of the road, the Traffic Mark and the Load Mark. Bridges at the top of the Ranking List are those that are most in need of treatment and therefore those which should receive priority in Works Programs, if economically viable.

  3.8 ECONOMIC EVALUATION AND RANKING

  Following the Screening process in the Planning Module of the IBMS-MIS, the bridges must be ranked in order of economic priority. This is also carried out in the Planning Module using the Economic Ranking option which system-analyses the bridges.

3.9 INDICATIVE ANNUAL AND FIVE YEAR PLANS

  After Screening and Economic Evaluation in the Planning Module, the IBMS MIS can produce Draft Annual and Five Year Programs. These Programs are 'indicative' only, until the data on which the treatment is based and the recommended treatments are confirmed (see Section 3.10). Furthermore, the costs generated in these programs are assumed costs which must confirmed by the Bridge Planners especially for rehabilitation. It is a requirement of the BMS that treatments must be verified in the field and should undergo a Treatment Strategy evaluation in the IBMS-MIS Programming Module.

  

3.10 DATA VERIFICATION, FIELD SURVEYS AND TREATMENT

STRATEGIES

  The outputs from the Screening process are recommended treatments, such as Replacement, Rehabilitation or Widening, and an indicative cost for the treatment. The recommended treatment must be confirmed. This will involve: x verifying the data by checking the Inspection Reports and photographs x carrying out field surveys if necessary to confirm the treatment or alternative treatments, especially for major work x ordering Special Inspections if necessary (particularly for extensive concrete repair or scour protection work). Reference should be made to all available Reports such as Detailed Inspections, Special Inspections, Manual Bridge Data File, and Photographs, road data etc,. Treatment Strategies are prepared using the Treatment Strategies option in the IBMS-MIS Programming Module. This basically involves considering 2 or 3 alternative treatments, determining the NPV of each, and adopting the one with the lowest NPV (over a 10 year period). Costs include owner costs and road user costs. Treatment Strategies must be prepared for all elements with Condition Mark 2 or more, so that they are repaired or replaced to restore the condition of the bridge and all its components to at remaining life of at least 10 years after treatment. If this is not the case, then other treatments within the 10-Year planning period must be specified and included in the analysis of the Treatment Strategies. Bridges are then economically-ranked to finalise the proposed bridge list.

  3.11 PREPARATION OF DESIGN PROGRAMS

  The IBMS-MIS is used for preparing the program for bridge design. Wherever possible, bridges should be designed one year before construction is scheduled. This is particularly important for long span and multispan bridges, where alternative bridge locations and more extensive site investigations need to be performed.

  The IBMS-MIS includes an option for establishing the Design Program, based on the following:

  Year Activity

  1 Planning and Programming - prepare Replacement program for Year 2 and proposed Replacement program for Years 3 and 4. Prepare Design Program for year 2.

  2 Design Bridges.to be constructed in Year 3 and first 20% ranked for Year 4, and any Bridges for which Design was not completed for Year 2.

  3 Bridge Replacement implemented The activities of course follow a regular cycle, and are carried out each year.

  It is important that the lead time for design is taken into account when preparing the Annual Programs of Work.

  3.12 PREPARATION AND REVIEW OF BUDGET PROGRAMS

  Following Economic Evaluation and Ranking, the Bridge Projects are documented by the Planning Sections in the Sub Dinas Bina Marga and Dinas PU Bina Marga. DUP documents setting out the proposed lists of projects for funding in the following financial year, together with Draft Five Year bridge programs, are prepared before mid-September each year in accordance with the Ministry of Public Works planning time-table.

  Provincial proposals are reviewed by BAPPEDA, the Governor, and the Ministry of Home Affairs. Responsibilities are summarized as follows: (i) Programs of Works are prepared by the Planning Section in Sub Dinas Bina

  Marga or by the Sub Dinas Bina Program in Dinas PU Bina Marga; (ii) Programming is coordinated and assisted by the Sub Directorate of Bridge Design in BIPRAN; (iii) Planning Sections prepare DUP documents and Draft Five Year budget programs;

  (iv) DITPEL review projects proposed for APBN funding and send to BIPRAN; (v) Projects nominated for Provincial APBD funding are sent to the Governor's office for review by the Governor, BAPPEDA and the Ministry of Home Affairs.

  National Budgeting

  Bridge works proposals in Draft Annual and Five Year Budget Programs are reviewed by DITPEL and BIPRAN. Revised Annual Programs are incorporated in the SATUAN III document which lists all Annual budget proposals for Projects to be administered by the Directorate General of Highways.

  Programs for later years in Five Year Programs are adjusted by the Planning Sections in the Sub Dinas Bina Marga and Dinas PU Bina Marga after Annual Programs are finalized. SATUAN III proposals are negotiated by BIPRAN on behalf of DGH with BAPPENAS and the Directorate General of Budgeting in the Ministry of Finance. These negotiations are usually completed before the end of December. A revised SATUAN III document is submitted to the Ministry of Public Works at this time. The Projects defined in SATUAN III are individually documented in DIP documents. The Draft DIP documents are prepared by PERINTAL and DITPEL. Final DIP documents are jointly issued by BAPPENAS and the Ministry of Finance.

  Provincial Budgeting

  Provincial budgeting operates at two levels. Some Provincial projects are funded from APBN and Foreign Loans. These Projects must be reviewed and processed in the same way as National projects. Projects which are funded purely from Provincial resources are reviewed by the Governor and the Ministry of Home Affairs.
