Libyan reconstruction plan will start after the end of the current crisis, so effective management of resources is crucial as adopting time-cost optimizing tools. projects' success depends upon achieving their objectives, which makes project planning essential. Repetitive Scheduling Method (RSM) ensures continuous utilization of resources from location to location in linear projects to eliminate time waste. This study applied RSM in the electrical project scheduling of Sirt-Hone 400kv transmission project. A graph of crew's movement through locations without idle time was presented, leading to fast project delivery and providing more value to the owner. The scheduling was done for a single work crew's composition and production rate two times, one time assigning one contractor and the other time two contractors. The project duration in 1st case was 574 days with zero idle time, and in the 2nd case was 275 days with zero idle time. RSM facilitates it easy to perform several scheduling scenarios to compare idle time and project duration. The study is empirical evidence for production strategies based on Lean Construction principles in project scheduling using RSM. Libyan reconstruction plan will need an advanced scheduling approach as RSM for repetitive linear projects due to the scarcity of resources.
