Abstract
To understand delays in the Indian construction context, an exploratory survey was
conducted as a precursor to the development of simulation models. System Dynamics (SD)
was used to visualise the pivotal feedback relations that cause delays to evolve mechanisms
that reduce it. A community development construction project in India serves as the case for
modelling. Findings of the study suggest that definite causal feedback relations exist among
difficulties in financing the project, ineffective planning and scheduling, poor
communication and coordination by the contractor, conflict between the contractor and
other stakeholders and use of inappropriate construction methods and construction delays.
However, the modelling efforts reveal that the use of these best practices can reduce delay
significantly: provision of adequate project finances and cash flow, effective planning and
scheduling, adoption of appropriate construction methods and contingencies for rework in
the schedule.
