Many building projects performed poorly because they took longer than expected to complete; time management is, therefore, crucial for achieving the program objectives. This study examines time management in the Libyan construction sector from the perspective of the contractors. A postal questionnaire survey was sent to construction enterprises in Benghazi, and data was gathered from 53 respondents who were chosen through purposive sampling. The relative important index (RII) was adopted as the research methodology. As a consequence, it was discovered that the majority of respondents concur that creating a clear and adequate time management policy is critical for meeting project deadlines because doing so at the outset will guarantee the success of any project. Therefore, the majority of construction companies undertake management reviews on time management of the administration as an effective and useful tool for time management. A closer look at the 8 categories used to categorize the variables causing delays in Libyan building projects reveals that one of the main causes of delays is financial issues. It is advised to keep an eye on the time management aspect of building projects in Libya by using certain effective tactics like the Just-in-Time (JIT) approach and the precedence requirement.
