People typically use it to forecast a project’s cost, size, resources, effort, or duration. There are several tools and techniques recommended by the Project Management Institute (PMI) in the estimate cost process of the Project Cost Management expertise area. Cost estimation and budgeting are essential tools for planning in the construction industry and play a central role in both preconstruction and construction phases of a project. The unit cost should be developed from weighting the data that emphasizes the average value, yet it should account for the extreme maximum and minimum values. 5. General project management cost estimation techniques and tools are listed here (project management skills 2016), [13]: Tools and techniques in project cost estimation… (3.1 ) c an be used for weighting cost data from previous projects. The higher the number of team members the higher will be the project cost. By carefully analyzing these many reports, an average productivity rate of 70% is established. 13.2.3 Construction Cost There are many different types of estimation techniques used in Project Management with various streams like Engineering, IT, Construction, Agriculture, Accounting, etc. Estimation is the process of finding an estimate, or approximation, which is a value that can be used for some purpose even if input data may be incomplete, uncertain, or unstable.. Estimation determines how much money, effort, resources, and time it will take to build a specific system or product. construction projects is done by Pethkar & Birajdar (2014). ANN is new approach that is used in cost estimation, which is able to learn from experience and examples and deal with Where design and construction overlap, cost planning might run into the construction phase of a project.
