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.

如今，严重的缺陷阻碍了将社会标准有效地纳入公共工程采购中。造成这种情况的主要原因是建筑行业缺乏信息和客观的社会评估方法。因此，本文提出了一种协助机构在公共工程采购中纳入社会可持续性指标和客观评估的方法。此方法适用于使用设计-投标-建造交付的基础设施生命周期构建阶段的土木工程项目。八个社会类别和22个因素被组织为两个组织级别（项目和公司）。建议使用定量和半定量指标来评估建筑公司在其组织和项目中的社会承诺。此外，建立了两个汇总公式作为公共工程采购的评估标准。结果表明，可以根据当地情况确定指标在评估项目中社会承诺方面的重要性。此外，评估企业社会责任的方法还可以衡量和比较公司的业绩，而不论规模大小。所提出的方法可用于采购程序，帮助公共工程采购人制定透明的决策程序。
