Examples have generally been taken from practical situations. Indeed, students will find this book useful not only for passing examinations but even more during their professional career.
December Estimate quality refers to the delineation of quality requirements for the estimate. These requirements are set out in accordance with formal quality assurance standards. There may also be other expectations for the estimate which are not specific requirements, but may affect the perceived quality of the estimate.
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. The bidder ultimately will go out of business; the only question is how long will it take.
This can only be known after the project is completed. If the project ended up having a different scope or conditions, an unadjusted computation does not fairly assess the estimate accuracy. Predictions of the estimate accuracy may accompany the estimate. 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.
A Course in Electrical Installation Estimating and Costing
The accuracy of an early estimate relates to the estimate quality. 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.
High-quality cost estimates can be produced by following a rigor of 12 steps  outlined by the U.
Detailed documentation is recommended to accompany the estimate. Therefore, a good cost estimate—while taking the form of a single number—is supported by detailed documentation that describes how it was derived and how the expected funding will be spent in order to achieve a given objective. Additional documentation may accompany the estimate, including quantity takeoff documentation and supporting calculations, quotes, etc.
Although the pursuit of cost estimate accuracy should always be encouraged, a study in found that the estimates used to determine whether important infrastructure should be built were "highly and systematically misleading. When using an estimate which has no contingency to set a budget or to set aside funding, a contingency is often added to improve the probability that the budget or funding will be adequate to complete the project. See cost contingency for more information.
The estimate or budget contingency is not intended to compensate for poor estimate quality, and is not intended to fund design growth, owner changes, or anything else unrelated to delivering the scope as defined in the estimate documentation. Generally more contingency is needed for earlier estimates due to the higher uncertainty of estimate accuracy. The method used for most definitive estimates is to fully define and understand the scope, take off or quantify the scope, and apply costing to the scope, which can then be summed to a total cost.
Take advantage of home improvement jobs you may never have bid on before by relying on the solid cost figures in this reference. That's why so many home improvement contractors use this manual as their company price book.
You'll be able to quickly locate hard-to-find costs for demolition, foundations, framing, structural repairs, decking, deck repairs, window repair and replacement, door repair and replacement.
Provides manhours for each job, recommended crew size, and the labor cost for the removal and installation work. Many assembly prices are included to help you speed your estimates, just add linear or square feet to complete the estimate.
Material prices are current, with location adjustment factors and free quarterly software updates on the Web.
Gives step-by-step instructions for the work, with helpful diagrams, and home improvement shortcuts and tips from an expert. Recently added sections include: Restorative drying, water damage and mold remediation. Smart home electrical management systems prices that comply with U. Green Building Council standards for energy-efficient upgrades.
