Quality and safety are of paramount importance objectives of construction project after time and cost. Literature shows
numerous methods estimating the quality and safety of project numerically. After an extensive literature survey, this paper
provide a framework to determine the quality and safety of project through determining the quality and safety in each alternative
of each activity. A case study project is used to demonstrate the working of this framework. Besides, this paper present the review
of past work conducted for adding the quality or safety or both in the time-cost trade-off models. Review shows safety is rarely
added in time-cost trade-off models, while quality is extensively added in time-cost trade-off models. Furthermore, this paper
provides some recommendations and suggestions to improve quality and safety parameters in construction project
