Today, critical deficiencies hinder the effective inclusion of social criteria in public-works procurement. The primary reasons for this are the lack of information and objective social assessment methods in the construction industry. Hence, this paper proposes a method to assist agencies in including indicators and objective assessments of social sustainability in public-works procurement. This method applies to civil engineering projects in the infrastructure life-cycle construction stage using design-bid-build delivery. Eight social categories and 22 factors are organized into two organizational levels (project and company). Quantitative and semi-quantitative indicators are proposed to assess the social commitment of construction companies in their organizations and projects. Additionally, two aggregation formulas are established as assessment criteria in public-works procurement. The results highlight that the indicators' importance in assessing social commitment in a project can be defined depending on the local context. Moreover, the method to assess corporate social responsibility can also measure and compare a company's performance, regardless of size. The proposed method can be used in procurement procedures, helping public-works procurers develop transparent decision processes.

Various studies have been recently conducted to predict pavement condition, but most of them were developed in a certain region where climate conditions were kept constant and/or the research focused on specific road distresses using single parameters. Thus, this research aimed at determining the influence of pavement structure, traffic demand, and climate factors on urban flexible pavement condition over time. To do this, the Structural Number was used as an indicator of the pavement capacity, various traffic and climate variables were defined, and the Pavement Condition Index was used as a surrogate measure of pavement condition. The analysis was focused on the calibration of regression models by using the K-Fold Cross Validation technique. As a result, for a given pavement age, pavement condition worsens as the Equivalent Single Axle Load and the Annual Average Height of Snow increased. Likewise, a cold Annual Average Temperature (5–15 °C) and a large Annual Average Range of Temperature (20–30 °C) encourage a more aggressive pavement deterioration process. By contrast, warm climates with low temperature variations, which are associated with low precipitation, lead to a longer pavement service life. Additionally, a new classification of climate zones was proposed on the basis of the weather influence on pavement deterioration.

Rural roads play an indispensable role in economic and social well-being, especially in developing countries, contributing to achieving the Sustainable Development Goals. For this reason, it is necessary to plan these projects properly to guarantee their success. In this line, the objective of this research is to identify significant variables generating overruns in time and cost using empirical data of 535 rural road projects in Colombia from 2015 to 2018. Bivariate analysis, with statistical tools like Spearman’s Rho and Kruskal–Wallis, allowed identifying that higher values of variables like budget and project intensity are related to higher deviations in cost and time. Additionally, it was found that projects with shorter durations are reporting higher time overruns. The worst performers are projects executed in the year that council mayors start their terms, those developed in municipalities with more resources, and those awarded using a competitive bidding process. Multivariate analysis, through Random Forest, assessed the effect of considering all variables interacting simultaneously and ranking them in order of importance. The results demonstrated a relationship between cost and time performance, and that numerical variables are more significant than the categorical ones. This study contributes to a better understanding of the causes of delays and cost overruns on rural roads, providing useful insight for researchers and industry practitioners.

Lean philosophy introduces a new approach for maximizing value while minimizing waste, facilitating sustainable practices at the same time. Companies have become aware of these improvements and are demanding students well formed in Lean concepts. However, to meet this demand, universities must adapt their curricula to include courses that use alternative teaching methods to connect to real contexts. This paper seeks to analyze the benefits of lecture- and game-based learning for developing students’ understanding of Lean Construction Principles. A case study is carried out in the “Lean Construction” course of the Master of Planning and Management in Civil Engineering of the Universitat Politècnica de València. A combination of a traditional lecture and three simple games is applied. Descriptive statistics, the Mann–Whitney U-test, and the Wilcoxon test are performed to analyze the impact of each activity on the understanding of each Lean Construction Principle. Results highlight the importance of combining the lecture class with multiple games to effectively impart knowledge about Lean principles and their application in the construction industry. In addition, they emphasize the importance of selecting the game according to the Lean principle to be taught.

Scientific literature highlights the need to engage social sustainability more effectively in the construction industry through public procurement. Previous contributions have been focused on establishing strategies and defining guides to encourage and facilitate the inclusion of social criteria in public procurement. However, to reach effective results, the characterization of the current scenario needs to be clarified. With this aim, this research analyzes 451 tendering documents from 10 countries in terms of social sustainability. Three research questions are stated to characterize what the current main social criteria are, how these are defined, and what the differences and similarities are with respect to the inclusion of social criteria in tendering procedures at the international level. To analyze tendering documents, a quantitative content analysis that combines inductive and deductive approaches is developed. Descriptive statistics and statistical analysis based on correspondence analysis and the chi-square contingency table analysis are performed. The results show a lack of metrics to assess social sustainability objectively, the predominance of health and safety as the main social criteria that are included in public procurement, and the importance of the contract size in the number of social categories considered in procurement procedures. However, the main result of this research is focused on showing the important role that the variable “country” plays when the behavior regarding the inclusion of social sustainability is compared at the international level since significant differences are found between Anglo-Saxon and Spanish-speaking countries. Policies should be implemented to promote the use of social criteria and metrics in the award of projects and in the evaluation and monitoring of social performance in the construction industry.
