Approval grade estimate

The approval-grade estimate is normally produced after spending one quarter to one third of the engineering/architectural design dollars. It s focus is twofold with the first being verification of the completeness of the project scope (Is all we will do in the estimate ). The second focus item is improved accuracy and detail to better function as the cost control document for the balance of the project (Fig. 11). 

Additional engineering is used to remove factored values from the estimate by developing sufficient detail to allow the factored values to be replaced with estimated quantities and unit prices. Equipment purchases will be updated to reflect the input of quotations received for the equipment. The building details will be improved as well. The area sizes and layout will be finned up. The building estimate will be improved in the same manner, since it will now be based on takeoff quantities. The building room sizes will be given a first level confirmation. 

The approval estimate is the most important to the reputations of the managing engineers for the project. A successful project is completed on time, in budget, and gains a reputation for smooth and efficient operation shortly after dedication. This is not likely to happen by accident. The decisions on what is necessary for the smooth and efficient operation are made during preliminary engineering and funded by approval of this estimate.
