Cost estimating

Factors affecting the quality of the estimate include the people who prepared the estimate, how the estimate was prepared, and what was known about the project. An estimate at this level may be used to price various design schemes in order to see which scheme best fits the budget, or it may be used to price various design alternatives, or construction materials and methods for comparison.

On large projects it is common for estimators to specialize in disciplines that parallel design discipline specialization. Properly document this information for future use and guidance.

Cost estimate

Indirect costs include overheadprofitsales or use taxes, payment and performance bondsescalationand contingency. Contingencies for the aforementioned will be reduced as more design documentation is produced.

The Level 5 estimate will be used to evaluate sub-contractor bids and change orders during the construction process. Direct costs are itemized for all necessary parts of the project.

Keep these 4 steps in mind and you already have a framework to start making estimates. Similar Occupations The Similar Occupations tab describes occupations that share similar duties, skills, interests, education, or training with the occupation covered in the profile.

Determine from an outside source if there were subcontract or material bids provided only to certain bidders. Field cost reporting, when consistent with estimating procedures, enables estimators to apply the knowledge gained from these historical costs to future estimates, and help train field personnel in labor hour and cost reporting that provide the level of accuracy required.

Published quality requirements generally have to do with credibility, accuracy, confidence level, precision, risk, reliability, and validity of the estimate, as well as thoroughness, uniformity, consistency, verification, and documentation.

Additional Resources Accurately forecasting the cost of future projects is vital to the survival of any business or organization contemplating future construction. It is very important to have the cost estimator involved right from the start of the project to ensure that the project budget reflects the decisions made by the rest of the project team throughout the integrated design process.

RSMeans refers to this as, "Scope out the project," and, "Quantify. The Level 3 estimate provides a greater amount of accuracy, made possible by better defined and detailed design documentation.

In addition to construction costs, estimates for process or manufacturing areas require information related to the involved processes such as product line capacity, process layout, handling requirements, utility requirements, materials and storage required, service requirements, flow diagrams, and raw materials access.

Typically this is expressed as a range higher or lower as compared with the point estimate with an expected probability that the actual cost will fall in the range. State quantities and costs for all material, labor, equipment, and subcontract items of work.

Make other members of the project team aware of any problems with the project documents. They will review the various aspects of the project with the other disciplines involved.

This way they can be updated separately as new information becomes available. Using the same level of detail in both the value engineering studies and the base estimate is extremely important. One way to make those estimates is by determining the resources needed e.

The Level 2 estimate is based on the previous level of information available at Level 1, in addition to more developed schematic design criteria such as a detailed building program, schematic drawings, sketches, renderings, diagrams, conceptual plans, elevations, sections and preliminary specifications.

Being unable to complete a project risks public ridicule. It should also be noted that within each level of estimate preparation, not all portions of the design would be at the same level of completeness. For a discussion of project delivery systems.

The estimator with the most thorough knowledge of a project best serves the owner and project team, and has the best competitive advantage when preparing a bid.

Cost Estimating Welcome to the VTrans Estimating Resources website. This site provides information for the development of construction cost estimates for all Agency projects. This guide will be confined to cost estimating in the building construction industry.

Construction cost estimators can be contractually hired in many different ways.

Cost Estimators

They may be employed by the owner's representative/project manager, employed by the construction manager, employed as a member of a professional design team, or separately hired by the owner. In project cost estimating, estimators may create a three-point estimate of cost using optimistic, pessimistic, and most likely costs.

Alternatively, for projects that measure deliverables in units of time with fixed costs, estimators may use expected durations as the number of units and determine costs via parametric estimates.

An approximation of the probable cost of a product, program, or project, computed on the basis of available information. Four common types of cost estimates are: (1) Planning estimate: a rough approximation of cost within a reasonable range of values, prepared for information purposes only.

Also called ball park estimate.

Cost Estimating

The more accurate your estimate of project cost is, the better able you will be to manage your project’s budget. Therefore, estimating a project’s costs is important for several reasons: It enables you to weigh anticipated benefits against anticipated costs to see whether the project makes sense.

In project cost estimating, estimators may create a three-point estimate of cost using optimistic, pessimistic, and most likely costs.
