The construction industry is one of the largest sectors that contribute to the economy in the UK and Jordan due to the amount of investment and opportunities that it provides. To construct a new project, there are several stages which need to be followed to complete the project. The pre-construction stage is the beginning of any project, and contains many procedures and elements which prepare the project for the construction stage. The cost planning process is one of main elements that is involved in the pre-construction stage, and prepares the estimated total cost of the project before construction to ensure that it meets with the assigned budget of the client. Cost planning contributes from the beginning to the completion of the design stage to provide control of costs and avoid going over budget during the construction stage. This book highlights the factors that impact the cost planning process in the Jordanian construction industry due to the importance of this process. In this regard, the book aims to define the cost planning process and identify factors that affect this stage, and uses the UK construction industry as a benchmark to provide a comparison.
