Abstract: Construction project suspension is known to be one of the big issues that have a significant negative impact on the project and its participants. The paper's key goal is to adhere to the degree to which the project achieves its goals (timely and budgetary implementation). It also helps to understand the obstacles, challenges and causes that the project faces explicitly or implicitly, thereby providing background information for the delay. These factors will lead to a reduction in economic viability, forcing projects particularly in developing countries, to overrun and decrease in growth opportunities. Finally, the paper puts in a quantitative framework to calculate the delay effects and to predict the possible losses, using GSA algorithm to find the best solution for certain delays in construction projects. The unavailability of the client's serious evaluation of the bidders' 'real' technical capabilities through the tendering phase prioritises the awarding of bids to incompetent contractors, bringing them forward and winning the bids. GSA is a very easy solution to find, as most of its velocity is about zero.
