*1.1. Knowledge Gap*

According to Epstein and Roy [13], managers have widely acknowledged the importance of formulating corporate sustainability strategies. For companies that have decided to assume economic, social and environmental responsibility, the question is not whether corporate sustainability strategies should be applied, but how they should be applied [14]. Nevertheless, transforming the concept into action and genuine initiatives remains a challenge. In this context, it is challenging to choose the right sustainability strategies [13,14], which are a consequence of distinguishing these strategies and knowing which are important for business sustainability in the long term. Companies lack a strategic approach to the integration of sustainability because of poor information and substantial uncertainty, meaning that failing to consider sustainability in strategic decision processes can increase the complexity of decisions and uncertainties [15]. From the firm's perspective, it is important to decrease uncertainty and achieve consistency with the purpose of promoting stability conditions. The integration of corporate sustainability into strategic managemen<sup>t</sup> offers a potential approximation to address these challenges [15]. This complexity is especially related to long-term vision in the context of sustainable development and stakeholder commitment [16]. Thus, different types of strategies are related to different sustainability levels [17], which can be identified both in the literature and in practice [18]. However, this identification is less clear in the construction industry because this industry has failed to consistently prioritize its strategies. Decision-makers need clear sustainable criteria to evaluate their strategies.

The knowledge of which sustainable strategies will be applied in the construction sector will enable design strategies, clarify sustainability concepts and facilitate the fulfillment of the proposed objectives through systematic application. The diagnosis of sustainable construction strategies is useful for identifying the sustainable strategies that are applied in the construction sector and the needs to be met to achieve a sustainable construction industry in Chile.

The purpose of this research is to diagnose sustainable construction strategies implemented in Chile by construction companies, uncover which strategies are applied and analyze the main associations that favor the development of sustainable construction firms. Therefore, this study contributes to mapping the strategic behavior of construction firms in terms of corporate sustainability and identifies the gaps that need to be solved to advance toward a sustainable construction industry.
