ScienceDirect First International Symposium on Risk and Safety of Complex Structures and Components Monitoring and Control of Schedule and Cost Performance in Facade Conservation Rosário Oliveira* Department of Civil Engineering, School of Engineering, Polytechnic of Porto, 4200-485 Porto, Portugal Feedback is crucial to the success of any project. Information on performance and project progress, at the right time and addressed to the manager, allows to identify and anticipate problems, and consequently make necessary adjustments to keep it within the limits of time and cost. Earned Value Management (EVM) is a technique used to measure the progress of a project. EVM provides information that enables integrated schedule and cost monitoring by providing performance indicators on the status of the project and estimates for completion. This article describes the application of the EVM technique to a contract for the rehabilitation and conservation of facades of a building. This case study was chosen to test the use of the EVM model. We conclude that this model presents satisfactory results and its implementation demonstrated easily and effectively in the control of rehabilitation and conservation of facades. The application of EVM has shown that it is possible to evaluate the performance of short term works with low complexity of tasks, since control parameters are calculated to quantify deviations of time and cost and to make relevant decisions about the work strategy. However, the EVM should be used to make an overall analysis of the work performance, and in the monitoring of schedule and costs it is necessary to identify the tasks that contribute most to the deviations and then make the control of their resources to adopt appropriate corrective measures. © 2019 The Authors.
