Construction projects are increasing in complexity and thus more contractors are becoming more reliant on subcontractors that are trade specific to complete a project. Since a large portion of the work is subcontractor-driven, the success of a project related to time, money, and quality is highly dependent on the work that the subcontractor completes. Job success is also highly dependent on the general contractor’s relationship with subcontractors and the clarity of goals that they set. This research created a tool in the form of a survey to evaluate the subcontractor’s performance at the end of the project. The questions created for this survey were based on a literature review and evaluation of the general contractor’s processes & programs. Based on this review Critical Success factors and Key Performance Indicators were identified, to evaluate a subcontractor performance. Some of this CSFs and KPIs included Schedule/time, Money, Quality and Safety. For the purposes of this research, the electrical and mechanical subcontractor of three projects of similar size and volume were evaluated by the onsite general contractor teams. The survey was tailored to the role that the survey taker held on that project, such as Project Manager, Engineer, or Superintendent. The results and review of this survey succeeded in collecting qualitative data that focused on providing actual feedback and insight about the subcontractor’s performance from the review of each GC employee. Results from this sample showed that the subcontractor’s foreman and project manager involvement (or lack thereof) was a large factor in the positive and negative performance of a subcontractor respectively. Those subs with good leadership and project management support ranked more favorably overall and higher in each individual category. The review of each of the performance cards by the general contractor employees noted that the survey can be beneficial as input for future projects and repeat subcontractors, to continue building relationships and to set the next project up for success.
