AB  - The line of balance (LOB) plays an important role in the implementation of Location-Based Planning and Control (LBPC), inducing most activities to be carried out at only one production rate and enabling the established deadlines to be met. Monitoring deviations from these deadlines is essential for project success, particularly in the construction industry. Rhythm deviation, an indicator rooted in Lean Construction principles and closely linked to LBPC, reveals the interference of critical tasks with other project activities and enables the analysis of how rhythm deviation of critical activities affects the project's deadline deviation. Analysing deadlines using the LOB technique in combination with rhythm deviation helps identify which activities are associated with project delays and advancements, allowing for corrective actions to improve workflow. However, this topic receives limited attention in the literature. The aim of this research is to propose a Deadline Deviation Index for monitoring and projecting delays and advancements in construction projects based on LOB and rhythm deviation data. This paper adopts an Action-Research methodology within a Case Study Approach. It presents findings from a case study involving 12 residential building projects that utilized location-based methods for scheduling and control, alongside rhythm deviation for monitoring critical processes. The results underscore how integrating the LOB technique with rhythm deviation enhances workflow and deadline management, thereby refining the sector's ability to estimate delays and advancements.
