Improving Performance in Mining and Construction Projects An Integrated Method Based on the Triple Constraint, Change and Risk Management with Normalized Databases

Globally, construction projects, particularly in the mining industry, face growing challenges related to efficiency, sustainability, and resource management. In Peru, a key player in global mining production, these challenges are exacerbated by complex geographical and social conditions. This study presents a comprehensive project management methodology, called the Master Plan, designed to overcome the limitations of traditional approaches focused on the triple constraint, risk management, and change management. The article details the development of an advanced model based on normalized and standardized databases, structured into four stages: bidding, planning, monitoring and control, and performance evaluation. The method's validation is conducted through a case study of a mining project in Puno, Peru, where performance indicators such as the Cost Performance Index (CPI) and the Schedule Performance Index (SPI) were assessed. A comparison with eight mining projects demonstrates that the proposed model optimizes costs and timelines compared to traditional approaches. This research enhances project management in the mining and construction sectors, highlighting the importance of information integration and standardization, as well as proactive risk and change management.
