Construction projects often go over budget and take longer than planned, causing problems for everyone involved. To understand why this happens, a study looked at the roles of key people like owners, consultants, and contractors. They found that these stakeholders play a big part in whether a project stays on track financially. By identifying the main reasons for cost overruns and getting input from experienced professionals, the study suggests ways to prevent these issues in the future. This research helps us see how important it is for everyone involved in a construction project to work together to meet cost goals and make the project a success.
