The article deals with the studies related to the production of precast segments for the Tapovan Vishnugad HEP project (TVHEPP) in Uttarakhand, India. The project and its significant characteristics, and the management aspects related to productivity improvement are presented. The Tapovan Vishnugad hydroelectric power project (TVHEPP), a run-off river scheme, includes the construction of a barrage on the Dhauliganga river, a major tributary of Alaknanda River, near Tapovan, Uttrakhand; a 12 km long and 6.24 m diameter circular head race tunnel (HRT); and an underground powerhouse near Helang for 520 MW power generation. From the findings of work sampling and the questionnaire survey, the problem areas for nonproductive works were identified. A list of improvement points were made to improve the productivity. Subsequently, a simulation model using EZStrobe software was developed to forecast productivity levels, and the expected improvement was quantified in terms of the production cost of segments.
