Subcontractor selection in private infrastructure construction was examined because inconsistent evaluation practices and limited documentation had increased project risk exposure in many organizations operating in the Czech Republic and the European Union. The purpose of the thesis was to develop a practical subcontractor risk assessment matrix that supports consistent decision making throughout prequalification, tendering, delivery, and close out. The objective was to strengthen transparency, traceability, and proportional governance in supplier selection. The intended users are procurement teams, project managers, and senior management responsible for contracting decisions.
The study was carried out using semi-structured interviews, document review, and design-oriented development work. Interviews were used to identify commonly observed risk factors and control requirements. Document analysis clarified current procedures and evidence needs. The risk matrix was designed as a Microsoft Excel-based tool supported by likelihood-impact-consequence scoring, standard supplier evidence requirements, and approval gates.
The resulting framework provided a structured way to evaluate subcontractors with clear scoring criteria and linked documentation. It offered a defined link between assessed risk levels and contract control measures. The main conclusion was that a transparent and repeatable selection process reduces uncertainty in supplier decisions and improves accountability. Further development was recommended through testing the matrix in additional tenders and refining scoring thresholds based on observed outcomes.
