Present study aimed to integrate Geographic Information Systems (GIS) and Building Information Modeling (BIM) in conjunction with multicriteria decision-making (MCDM) to enhance infrastructure investment planning.

This analysis combines GIS databases with BIM simulations for a novel highway project. Around 150 potential alternatives were simulated, narrowed to 25 more effective routes and 3 options underwent in-depth analysis using PROMETHEE method for decision-making, based on environmental, cost and safety criteria, allowing for comprehensive cross-perspective comparisons.

A comprehensive framework proposed was validated through a case study. Demonstrating its adaptability with customizable parameters. It aids decision-making, cost estimation, environmental impact analysis and outcome prediction. Considering these critical factors, this study holds the potential to advance new techniques for assessment and planning railways, power lines, gas and water.

The study acknowledges limitations in GIS data quality, particularly in underdeveloped areas or regions with limited technology access. It also overlooks other pertinent variables, like social, economic, political and cultural issues. Thus, conclusions from these simulations may not entirely represent reality or diverse potential scenarios.

The proposed method automates decision-making, reducing subjectivity, aids in selecting effective alternatives and considers environmental criteria to mitigate negative impacts. Additionally, it minimizes costs and risks while demonstrating adaptability for assessing diverse infrastructures.

By integrating GIS and BIM data to support a MCDM workflow, this study proposes to fill the existing research gap in decision-making prioritization and mitigate subjective biases.

The purpose of this paper is to propose recommendations and guidelines for the initiation phase of a public–private partnership (PPP), focusing on the electricity sector in Brazil.

A literature review allowed gathering international best practices, while brainstorming meetings and document research permitted acquiring data from the Brazilian electricity sector through a multiple case study of 12 projects. By applying benchmarking principles to compare findings, the paper proposes guidelines and recommendations, which culminated in a final framework for implementing PPPs.

The created framework structures a series of recommendations with application in PPP projects. Also, the paper gathers worldwide best practices, which could increase the rate of success by avoiding problems throughout the other phases of a PPP project.

This paper addresses the electricity sector. Due to the singularity of such infrastructure enterprises, it is possible that the framework suggested is not entirely applicable to other enterprises, being a suggestion for future studies to perform an adherent test. Also, validating this framework is not in the scope of this project.

The use of a framework on PPP implementations brings attention to necessary efforts on previous phases of projects, which can avoid financial and technical problems, improving the reliability of PPPs.

The application of guidelines and recommendations on the electricity sector has not appeared with such focus in previous studies. The paper provides a practical manner to upgrade the process and suggests a model for implementing PPPs.
