From this aspect, an estimate provides a guide of how much it will cost to deliver something. Figure 2.1 below displays the relative accuracy of each type of cost estimation process. This estimate shows required materials, labor, time to complete the project, complete cost details and overhead and also contractor profit. Conclusion. Simply put, you will break the project work into its smallest work components. This is a key concept for your PMP preparation related to Project Cost Management.

It has not been confirmed a significant relationship between the level of education of project managers and using bottom-up approaches, cost estimates of construction projects. Project managers often tend to make over-estimations to stay on the safe side. Total Cost management; 4. In project management, an estimate is an approximate calculation of the effort and costs to complete the task or the project. Estimate Costs (Planning) Three interactive processes are required to manage costs … 4.3 Project Management 18 5. It needs to be divided into each task and allocated as much as practical. In order to begin project budgeting, you first need to understand types of costs and cost estimates. Types of estimates 1. The first step in creating a project budget is to generate cost estimates. The term "project cost estimate," as used during the project development process, includes all direct capital outlay costs, including right of way, structures, and landscaping, but does not normally include indirect capital outlay support costs. Planning the estimate; 8. Project Report. Therefore, it is considered a better estimation method. In this article, you will learn about the types of costs associated in a project, which are then explained by using examples. The other processes are: [1] Order-of-magnitude. Rates. Preliminary Cost Estimate: The preliminary cost estimate is also known as an approximate cost estimate, abstract cost estimate or budget estimate. Types of Cost Estimates in Project Management: There are different Types of Cost Estimates in Project Management. TYPES OF ESTIMATES Prepared by:- Simarpreet Singh A.P, Civil Engg. Therefore, it should be made before to start a project. There are three basic types of contingencies in projects: tolerance in the specification, float in the schedule, and money in the budget (CIRIA 1996). Cost estimating. TYPES OF COST ESTIMATES IN PROJECT MANAGEMENT. Such tools can allow for rapid consideration of multiple cost estimate alternatives. Customers; 7. It defines what costs are required for each deliverable. Patrascu (1988:115) observes, "Contingency is probably the most misunderstood, misinterpreted and misapplied word in project execution". Project Management Chapter-5 Estimating Project Times and Costs. This paper deals with project cost contingency. 3 1. Project estimates are projections of costs, task completion times and resource needs for a project, often broken down by activity. These two estimates vary significantly with the actual project cost but the differences are justified in the analysis. Initial, high-level estimates are often used in the earliest stages of project planning and can determine whether or not a project is ultimately pursued. 1. The following are common types of cost estimate. This type of estimate is prepared in the initial stage of a project. Page iv GAO-20-195G Cost Estimating and Assessment Guide . Expert judgment – estimation based on previous knowledge and experience of the estimator. Contingencies – Indicates incidental expenses of miscellaneous character which cannot be classified under any distinct item. As can be seen, cost estimation forms a pylon in the cost management process and as a result in project management. There are four other types of estimates, three of which are more accurate than the study estimate. Types of Costs Fixed and Variable Costs. Project Cost Management. An equipment factored estimate is produced by taking the cost of individual types of process equipment, and multiplying it by an "installation factor" to arrive at the total costs. Building the estimate 6. The resource management feature on ProjectManager.com is another tool that can help you achieve a more accurate project cost estimate. Project Cost Management is defined as the process of planning and controlling the project cost effectively. The types of costs in projects are: Fixed, Variable, Direct, Indirect, and Sunk costs. • Project Management Estimating Software – use of project management cost estimating software applications, computerized spreadsheets, simulation, and statistical tools.

Being able to make accurate cost estimates is key to delivering a solid project plan. • Vendor Bid Analysis – determination of what the project should cost based on a review of vendor bids/proposals. For this type of estimate, an estimator needs complete set of drawing and instruction manual of the project. Expected values of project costs and construction periods should reflect past experience that actual values achieved have normally been far in excess of those estimated originally, particularly those estimates produced at the early stages of project preparation. Please refer to PMBOK® Guide Fourth Edition, page 167, figure 7-1. 1. Cost estimating is one of the most important steps in project management. Here, you will calculate the cost of every single activity with the highest level of detail and roll them up to calculate the total project cost. In practice, this has proven to be quite a useful method since a substantial part of total project costs are made up of equipment.
