A Case study of Ganga river Project is taken and possible risk is identified which on further technical risk assessment is done.

2. CASE TAKEN BIHAR NEW GANGA RIVER PROJECT
AND
TECHNICAL RISK IDENTIFIED
• UNPREDICTED RIVER FLOW AND SOIL CONDITIONS DELAY CONSTRUCTION
• BRIDGE MAINTENANCE IS NOT SUSTAINABLE, AND FUTURE CAPACITY FOR BRIDGE OPERATION AND MANAGEMENT IS WEAK
• PROJECT START UP IS DELAYED AND DISBURSEMENT IS SLOW
• IMPLEMENTATION CAPACITY IS NOT ADEQUATE
• PROCUREMENT (MANPOWER & MATERIALS)
• IMPROVEMENTS TO COMPLEMENTARY NATIONAL AND STATE HIGHWAYS ARE DELAYED
• INADEQUATE AND INCOMPLETE DESIGN
• INACCURATE ASSUMPTIONS ON TECHNICAL ISSUES IN THE PLANNING STAGE

Risk Factor Priority Mitigation Measures
1 Unpredicted river flow and soil
conditions delay construction
(a)
High Historical hydrological data collected by the
Central Water Commission and supplemented
with information available in the past reports and
literature.
2 Bridge maintenance is not
(b)
Medium The TA will strengthen the institutional capacity
of the Government of Bihar and BSRDCL to
effectively manage and maintain major bridges in
Bihar and develop sustainable operation and
maintenance plans for bridges in Bihar.
3 Inaccurate assumptions on technical
issues in the planning stage
(c)
Medium Value Engineering and Effective Planning team
with experienced members will conduct meetings
and review decision at Design stage.

Medium Collaborating Software use for proper
feedback and communication at various
stages of construction
5 Improvements to complementary national
state highways are delayed
(e)
Low National Highway Development Project
(NHDP) appointed to look after the
construction of Roads
6 Decision implementation capacity is not
adequate
(g)
Medium The PMAE team will to support BSRDCL by
providing overall project management
assistance and monitoring the
implementation of safeguards, including
the EMP and other measures related to
environmental protection.

(h)
Medium Procuring from local availability and
appointing the best logistic company for
material procurement.
