it accessible through internet and roll it out to the all the field offices across the State. This will
help HPPWD in better Project management, improved reporting and dissemination of
information. HPPWD also desires to establish a computerized Road Maintenance Management
System (RMMS) so as to streamline the road maintenance activities of the Department. Beside
this, HPPWD also want to integrate core activities of the Department, by way of automated
business processes and work flow system and to facilitate informed decision making, using
electronic information database, captured while working through the system

preparation of running-account and final bills.
Payments for executed work and fund flow
Monitoring and review of work and administering the Contract for work
Inspection of works by Engineers at various levels, exercise of quality control

Proposed Hardware & Network Architecture
3 Proposed Technology Architecture
The proposed solution will be based on N-tier Service Oriented Architecture with separation of
business logic from application, database and presentation.
A service-oriented architecture (SOA) will allow PWD to establish a flexible, robust infrastructure
so that the SI can build, deploy and integrate services, independent of applications and the
computing platforms on which they will run and will make PWD business processes more flexible.
SOA will also ensure that the services to be provided and consumed, now and in the future as the
system scales up as per PWD requirement. In addition, further integration with existing or new
systems is required. The use of SOA will also ensure that connectivity to services will be as flexible
as required and applications will not be tightly bound to each other.
A modular approach has been adopted for the development and implementation of various
project modules such as Budget allocation and management, Construction Works management
System, Project Planning Management System, Building and Asset Information Management,
Integrated Inventory Management, Road Repair Management System etc. Project should ensure
interoperability with complete independence among various modules.
The framework is proposed to include front end for the application, Application layer, service
components, channels of delivery, integrated ‘To-Be’ processes, Database logic layer as the
critical elements of the model. These elements provides for allow comprehensive functionality
to proposed solution for the PWD, Himachal Pradesh.

Proposed Hardware & Network Architecture
3.1 Network Connectivity
Network Architecture
Networking forms the back-bone of any IT infrastructure setup in the current period. Data and
functional integrity between the applications installed at different locations depends on the
networking connectivity between the locations. Reliable and high bandwidth connectivity
between all the offices of PWD will make a centralized architecture feasible that will remove
duplicate data entry and make the information flow across the hierarchy smooth. However, it is
important to note that the implementation of a state-wide network infrastructure is a part of
national e-Governance programme; therefore PWD shall use HIMSWAN for the implementation
its proposed ERP solution. HIMSWAN should be utilized as the communication backbone for
connecting HPPWD offices (up to Divisional Office level). Offices outside the span of HIMSWAN
Point of Presence (POP) can be connected through optimal connectivity means like Optical Fiber
Cable (OFC) or leased lines as per requirement and availability. However, wherever, it is not
possible to have network connectivity using these options, department can consider using
broadband connection over VPN.

PWD, Himachal Pradesh
Proposed Hardware & Network Architecture
But, looking at the pace of implementation and connectivity problem at the offices located at
remote locations, it is therefore suggested that all the proposed ERP solution shall have the
architecture that works in both offline and online mode with the central server at the State Data
Centre. The architecture should be such that it supports the synchronization of data with
centralized database when the systems work in offline mode to consolidate the data at the
central database (refer Figure). The offline and online mode is dictated by the reliability and
bandwidth of the connectivity between the office and the central server. The offline mode shall
be case only when the required reliability and bandwidth is not available. It is hoped that when
the HIMSWAN implementation is fully implemented all the offices of PWD shall be functioning in
online mode.
