ABSTRACT

The failure of a project can be attributed to delays in implementation time and the arising issues. To prevent project failure, systematic project management is necessary to optimize both time and cost. Project crashing serves as a method to reduce project duration by streamlining activities with minimal cost. The analysis involves shortening the implementation time through two alternatives: overtime for 3 hours and additional work shifts. The research focuses on the replacement project for the Bondoyudo Bridge in Lumajang, East Java. The findings reveal that adding an hour of work incurs a cost increase of 0.94% compared to the project's normal conditions, while reducing the implementation duration by 0.55%. For a more expensive addition of 2 hours, the cost increases by 1.22%, with an implementation duration 1.09% faster than the normal duration. Furthermore, adding 3 hours results in a 1.19% cost increase and 1.64% faster implementation. Alternatively, implementing a shift work system increases project cost by 2.01%, but reduces implementation duration by 7.65% compared to the normal duration
