Abstract. The socio-economic conditions of a country and the overall practices of the construction industry towards Sustainable Construction (SC) are critical factors to define the foundations for developing and carrying out a strategic plan to advance in sustainable construction. This paper reports the results of a study about SC practices currently implemented by construction companies and discusses the level of awareness and knowledge, barriers and drivers of SC that were found in building and infrastructure construction companies. In addition, it analyses the influence of the company size on SC practices. research results show that Chilean construction firms are in an early stage of the path for achieving SC. Their practices towards SC are highly dependent of the company's size and its core business. Main barriers towards SC are the lack of financial incentives, lack of integrated design, and affordability whereas company's tax reduction incentives related to the level of investment effort on SC would be a key governmental policy to promote sustainability. The results of this study might be particularly useful for other countries, particularly developing ones, and for government policy making.

PurposeTo analyze the role of construction site supervisors, including foremen and general foremen, as front‐line managers. The role is treated as a critical labor function and a source of value‐added for construction management.Design/methodology/approachAn original model based on the labor competency management framework is proposed for training, developing and certifying construction supervisors in Chile and other developing countries. This model was developed from the findings of a case study in which the competency framework was applied to a specific construction company.FindingsThis case study has demonstrated the significant potential of the competency framework for the Chilean construction sector, with its underdeveloped human resources management methods. In particular, this framework can be an effective approach to achieving the competencies required by construction site supervisors who must deal with inadequately trained workers, as is the case in many developing countries. The structured approach of the competency framework can help companies create more objective schemes for the design and implementation of training programs.Practical implicationsThe application of the competency approach can greatly improve the human resources management function in construction companies as well as the site performance of their personnel. The findings obtained so far in Chile can also be projected to construction companies in other developing countries in the region.Originality/valueThis paper presents the first application of the competency framework to a Chilean construction company. This study is also original in the sense that the application described here was carried out in an environment where human resource conditions are quite deficient.

Construction organizations in developing countries, approach risk management in construction projects by using a set of practices that are normally insufficient, produce poor results often, and limit the success of project management. This paper describes the development of an instrument based on an organizational maturity model for evaluating the risk-management capability of construction organizations. This instrument has been applied to both, clients and contractors and is part of a general knowledgebased system. Outcomes of this research will allow a client or contractor first, to develop or improve its project risk management capability based on international and local best practices and second, to continuously improve the performance of this function along the realization of new projects. The novelty of this approach is that it addresses the risk management function from a knowledge-based perspective and that it will be based in a web application that will be available to every organization.
