Terms of Reference
1. Background
The rural electrification program in Bangladesh has progressed significantly through a
variety of initiatives. These initiatives have contributed to building the capacity of
Bangladesh Rural Electrification Board (BREB) to plan, design, and construct distribution
system according to international standards. The program has also contributed to
developing the capacity of BREB to organize Palli Bidyut Samities (PBSs) for management,
operation, and maintenance of distribution systems. Over the years, the distribution
network in PBSs, the electric load, and consumers have grown dramatically to a very large
size consisting of about 20 million consumers. This has also made the system technically
complex. As a result, the service to consumers and other stakeholders are being affected. In
order to provide a better service to its stakeholders BREB now proposes a number of
initiatives such as automation of the network, developing modern O&M systems and use of
technologies such as Geographic Information Systems (GISs) in order to improve the
technological environment and enhance corporate capabilities. The main purpose of the
current assignment is to introduce GIS based technologies to all areas of utility practice in
BREB and PBSs.
BREB has already commenced a program of securing GIS based information in a number of
PBSs. However, establishing the data requirements to fully operationalize GIS practices in all
PBSs will take considerable time. Hence the strategy to be adopted in the present exercise is
to continue to carry out the routine work of data collection by the PBSs and to use the
current consultancy assignment to develop this program in accordance with established
best practices, train the PBS personnel in carrying out all related activities and to introduce
GIS applications where possible as and when the data requirements are met. In this way, the
effectiveness of the program will be better realized and there will be only a limited time lag
between data collection and its usage.
2. Objective
The objective of the assignment is to develop a GIS framework for use in BREB and the PBSs
so as to modernize the planning, network operations and maintenance practices and
consumer interactions.
3. Scope of Services
The consultant’s scope of work will essentially consist of two parts: the first related to the
development of best practices in GIS data collection and the second related to its
applications for use in utility practice. Initially the consultant should review the current
practice of GIS data collection and provide proposals for its improvement and
modernization. Thereafter the consultant will carry out a pilot study in a selected PBS to
demonstrate the best practice to be used in GPS data collection on a pole by pole survey.
2 | P a g e
The pilot study will also be combined with a training exercise for PBS staff who will finally
carry out the work in each of the PBSs. In this manner with the work spread out over each of
the PBSs, it is envisaged that the conversion of all PBS utility practices to GPS based
programs will be carried out within a short period of time. The second part of the
consultant’s duties will consist of development of applications to utilize the GPS based data
for all forms of utility practice. For this purpose, the consultant will need to develop a well-
planned database system and a number of application software and programs. In some
instances, the consultant will assist BREB in securing commercially or open source available
software and link their application to the GIS based database.
The scope of the services of the consultant will include but not be limited by the following:
3.1 Review and recommendations on BREB procedures for GIS data collection
The consultant will review current procedures and techniques used in GIS data collection in
relation to securing of GPS coordinates and the equipment data input and storage and
recommend procedures to bring the practices up to acceptable international standards. The
activities to be done will include:.
� Update Existing Pole numbering system of HT (33 kV and 11/6.35 kV) and LT lines
� Update GIS inventory Sheet (Survey Form)
� Upgrade equipment record forms for items such as voltage regulator, power
transformer, distribution transformer etc.
� Update transformer unique numbering system. Transformers information should be
unique and linked up with pole numbering.
� Introducing of geo-location capturing in all kinds of survey forms and staking sheets
and build as digital format for software used.
3.2 Primary GIS data collection
Primary data collection is the base data collection for GIS development in a power system.
This consist of gathering electric distribution system information such as grid substations,
primary substations and their feeder wise data which include network data on a pole by
pole basis of both HT and LT lines. It also includes information on the electrical equipment
installed such as transformers, voltage regulators, ACRs/OCRs, capacitors, meters and line
conductors. Information on consumer characteristics and their connection to the network
(location and connection of the service pole) is also needed.
The main task of preliminary data collection for the entire BREB/PBS system will rest with
the respective PBSs. However, the consultant will carry out an exercise in the collection of
preliminary data at a selected PBS to serve as a model exercise. During this exercise the
consultant will train sufficient number of PBS personnel in the carrying out the related
duties and establish best practice methodologies in the collection of the primary data for a
utility GIS program. The activities to be carried out will include:
���� Collection of pole by pole data for HT and LT lines and recording the locations by a
Precise GPS receiver
���� On-site processing of GPS data and conversion to GIS data format
3 | P a g e
���� Verifying accuracy (to less than 1 meter) of field data of geographical locations
���� Keeping records appropriately and correction of defective data (at every following
day)
���� Daily uploading/Digitizing the field data collected to the database
� Conductor information, equipment information and device information collection
during the pole by pole survey by GIS inventory sheets
� Collection of data related to grid substation, switching station, sub station
� Collection of data related to important land marks using appropriate forms
���� Collection of information of transformer and other equipment/devices from
‘Equipment Record Cards (ERCs)’ and related PBS documentation and integration of
the data with electric distribution system’s GIS Database. A computerized database
management program providing a suitable data assembly software will be needed
for this purpose
� Pole and Equipment information will be collected through Precise GPS Equipment or
Temporary Stations (TS) and a short questioner survey. A digital data input format
can also be used by applying some macros with the Precise GPS Equipment and
Tablet Mobile based questioner survey and data input. In this case the Existing
Equipment records card’s digital format can be used.
� Pole oriented consumer and equipment data is maintained at each PBS. Transformer
record cards as well as records of other equipment in the system are also
documented and updated regularly at each PBS. This data needs to be uploaded to
the database.
Information to be captured in a pole by pole uploading of data includes the following:
Electric Pole Unique pole number with feeder name/ID, Latitude, Longitude,
Pole Size, Pole Materials, Pole Type, Pole Fittings, Pole Environment, Conductor
Size/Type, Conductor Phase Sequence, Conductor Line Voltage (KV), Transformer
Capacity (KVA), Transformer Phase Connection, Guy unit, Jumper Size, Devices.
Electric Lines Capacity, type of all HT, LT, overhead and underground line from grid source to
consumer end.

3.3 Geo-referencing
The GIS Data must be geo-referenced in respect of Bangladesh’s coordinate system. For that
purpose data should maintain referencing GCP on Bench Mark.
3.4 Secondary data collection and Mapping
Secondary data is very important to develop the information needed for a variety of
applications to be used in a power utility. Thus, the primary data needs to be supplemented
4 | P a g e
by numerous secondary data that deals with the geographic features of the land,
characteristics of the population served or to be served, important institutions located in
the service area etc. The consultant will be responsible for the collection of the relevant
secondary data not only related to the pilot PBS where detailed work is being conducted but
also for the country as a whole, for use in other PBSs. However, while overall country
related data collection shall be facilitated and arranged by the consultant the collecting
much of the secondary data may be focused on that of the pilot PBS. Information to be
obtained includes:
� Processed geo-referenced satellite images or Arial photography information.
Accuracy level of these images could be ±0.5 meter aAer post processing
� Base maps with cadastral boundaries such as local administrative districts (village,
union, upazilla, district, division etc.), linear features such as roads (primary,
secondary, tertiary and quaternary), rivers, lakes, canals etc.
� Preparation of the Base Map of PBSs with demarcation of PBS
boundary/Area/Location should be geo-referenced in Bangladesh reference system.
� Demographic and social data such as population, house hold / settlement type etc.
occupation, stakeholder type can be collected from the statistical year book of
Bangladesh bureau of Statistics (BBS). Such demographic and social data would be
used for assessing future growth and trends such as projection of population and
consumers, and service area demarcation.
3.5 GIS Database Establishment and Analysis
The consultant needs to develop a fully functional GIS database and a Data Base
Management System (DBMS) for data processing, inquiry and analysis by various
departments of BREB and the PBSs. The GIS platform will be the latest version of the
Environmental System Research Institute (ESRI)’s ARCGIS (latest version). The DBMS should
consist of a set of software programs that controls the organization, storage, management,
and retrieval of data in various databases established. DBMS should support the application
programs and enable the transfer of appropriate data to various users.
Initially the consultant will carry out a Business Area Analysis so as to design the GIS system
requirements to the needs of all intended users and determine the appropriate
functionalities to be incorporated within the GIS. Overall the database structure may include
the access database, survey database, electrical network and analysis database and the
billing database plus any others as per the requirements of users. The specific structure of
data storage and GIS system architecture should be determined after discussions with the
various users to meet their various needs. A set of interactive macros for query and access
between the databases will need to be developed.
The data received from the Precise GPS Equipment and equipment records need to be
verified and error checked for accuracy and consistency. For example, the network data can
be checked with reference to the single line diagrams and geo-referencing with geographic
maps.
5 | P a g e
Basic analysis capabilities of the GIS shall include the following:
� Geospatial query and statically Analysis: this will include items such as geographical
queries like area and length calculations, details and quantification of various assets
and their physical locations, equipment status, computation of area served by
substations, feeders etc.
� Electrical query and analysis: some of the features will be processed with internally
developed software while items such as load flow analysis will be conducted using
commercially available software packages that will be linked to the GIS data base.
Internally generated query facility would include generation of single line diagrams
(SLD), connected kVA on feeders etc.
� Consumer related analysis: requirements would include features such as consumers
connected to each feeder and line section, energy consumed by feeder etc.

6. Methodology for carrying out the services
Initially the consultant will review the work already carried out in developing a GIS data base
and provide an assessment of its appropriateness. Thereafter he will suggest any
modifications and/or updates needed and assist BREB and the PBSs in carrying out such
changes.
The focus of this assignment is the development of a GIS data base and related application
software to be used in all of BREB and PBS activities. Developing the pole by pole GPS
coordinates and populating the asset attributes will mainly be carried out by PBS staff or
separate consultants. Nevertheless, the consultant will undertake a pilot exercise to
demonstrate the best practice and methodologies to be used in collecting the GPS
11 | P a g e
coordinates of network assets and attribute data. This pilot exercise will be carried out by a
team of experienced GPS specialists and will be used to train the PBS staff who will
eventually populate the data base in all PBSs. The pilot exercise and related training will be
carried out in one PBS. In parallel with the pilot exercise PBS staff or other consultants will
also carry out the collection of GPS coordinates and attribute data in this PBS under the
guidance of the consultant so as to populate the data base as quickly and as extensively as
possible. The GPS data collected in this PBS prior to the commencement of the assignment
will also be used in the analytical work that will be done in this PBS.
The consultant will use the data collected in the pilot PBS along with additional geographic
and other information that will also be developed to demonstrate the satisfactory operation
of all application software that will be developed in this assignment.
The selection of a suitable PBS to pilot the GIS development will be done after the
consultant commences duties by mutual discussions between BPDB and the consultant. The
selection will be based on the following characteristics:
1. A smaller area of service with less consumers
2. Where network lines and substation data are fully updated
3. Where equipment records are updated
4. Where Pole numbering is completed
5. An industrial Area could be preferable
6. A PBS with better transport/road facilities and more or less flat and high land terrain
7. More or Less Profitable and resourceful PBS
It is expected that the consultant’s GIS field team will be able to complete the needed pilot
field work in the PBS selected so as to demonstrate the use of all applications by the end of
the assignment. If this work can be completed before, the activity will be continued in
another PBS so as to enable continued training of PBS staff in completing the field data
collection work in a timely manner
7. Capacity Development and Training
A comprehensive training program shall be developed by the consultant on the GPS survey,
GIS development, Database Software, Electric Analysis Software, and Web GIS Software.
In addition the following training materials shall be provided:
Improvement of existing training programs: Currently there are Three GIS/GPS based
Training Programs being used in BREB for its staff development. The consultant will review
these training materials and update them to include the latest software and hardware
applications and usage and develop any additional training courses necessary. The currently
operating Training Programs are
1. Basic Geographic Information Systems (GIS) For Rural Electrification Program
This training program includes advance level GIS development works on GIS software. The
total Duration is 10 Days.
12 | P a g e
2. Application of Global Positioning System (GPS) and Introductory Geographic
Information System (GIS)
This training program includes Basic GPS Survey works related training. It is developed for
the field survey on handheld GPS receiver and Pole to pole information collection. The total
Duration is 05 Days.
3. Fundamentals of Geographic Information System (GIS)
This is a short training program for the GIS mapping also including field survey activity. It
includes the very basics of ArcGIS Software and handheld GPS receiver operation. The total
Duration is 05 Days.
Additional training programs: Additional to updating and improving the above training
material the consultant will develop a number of additional training courses and prepare all
required training material and documentation. The new training programs to be developed
include the following:
1. Training programs on each of the new electrical analysis software introduced in this
assignment as described in sections 5.4 and 5.5 needs to be developed. These should
be training programs at user level and should be comprehensive so as to enable a
number of users to be trained in BREB and the PBSs to be competent in the use of
these programs. The duration of each of these training programs should be around
10-15 days and include hands on demonstrations so as to enable the users to
become fully professional in the applications. With reference to the load flow
analysis software if a decision is made to continue with the existing Windmil
software the current training program for this software should be updated and
improved to include the GIS linkage application.
2. Training programs for the use of all software linked to the database such as for
entering the Equipment Record Card (ERC).
3. Training programs in the application of the desktop and web based software. These
should contain modules for usage of the programs, operation of analysis and query
facilities and maintenance of the programs.
4. Training program on the usage of the newly buildup macros including their operation
and linking up the macros with other software.
Overall a program to train the trainers consisting at least 10 Personnel need also to be
developed to carryout future training activities.
