Late completion of construction project compared to planned schedule is common in construction projects. Delays can create cost and time over run and disputes between client and contractor executing construction work. First part of the study focusses on determining reasons which contribute to delay in construction work. This paper doesn’t attempt to propose methods to avoid delays. The possibility of using extant time and cost forecasting methods to help project managers anticipate delays has been evaluated in second part of the study.

Construction of pre-stressed concrete (PSC) structures is becoming a common practice in various parts of the world, because of its better stability, serviceability, economy, aesthetic appearance and structural efficiency. Post tensioning is a method of reinforcing concrete or other materials with high strength steel strands or bars, typically referred to as tendons. The provision of large openings in pre-stressed concrete beams is necessary to accommodate utility services in residential, commercial, and industrial buildings. A post tensioned I-beam is analyzed by using ANSYS software and the deformation and stress pattern of beam is studied for different parametric conditions by changing the position of opening and different shapes of openings.
