Three accuracy measurements, correlation coefficient (R), Root Mean Square Error (RMSE) and Mean Absolute Error (MAE), were used to check the mathematical model and to compare the actual values with predicted values. ![]() The number of factors affecting the planning and scheduling of the repetitive projects has been identified through a questionnaire that analyzed its results using SPSS V22 software. The software (WEKA 3.9.1©2016) has been used in the process of developing the mathematical model. This study develops a mathematical model to forecast repetitive construction projects using the Support Vector Machine (SVM) technique. However, they need continuous development because of the evolution of execution methods, essentially based on the repetitive construction projects’ composition of identical production units. Repetitive planning and scheduling methods are more effective and essential. It should be integrated and flexible to accommodate the changes without adversely affecting the construction project’s total completion time. Due to the nature of unique repetitive construction projects, time contingency and project uncertainty are necessary for accurate scheduling. It is achieving the project within the defined deadline that required careful scheduling, that be attained early. 2.The second procedure is the following: (i) Under this modality of the procedure, in the first stage prospective bidders are requested to submit proposals on a partially developed technical specifications, and they are expected to contribute to the completion of the technical specifications and provide a methodology and work plan for carrying out the assignment.Each project management system aims to complete the project within its identified objectives: budget, time, and quality. In this second stage, if an agreement is reached, the technical specifications or terms of reference are finalized and the highest ranked firm is invited to first submit a financial proposal based on the agreed technical solution, and then to contract negotiations. This process is very similar to the quality-based selection (QBS) procedures used to request proposals from consulting firms when the Terms of Reference are difficult to define under highly specialized and complex requirements. (ii)Stage two is for receiving the final offer of the technically highest ranked firm. ![]() The proposal is evaluated and scored, and the firm with the highest ranked technical proposal invited for discussions with the purpose of reaching agreement on the proposed technical solution. In this first stage, bidders are requested to submit a technical proposal with their best solution for fulfilling the requirement. ![]()
