Performing meters and estimating principles, correctly and with high accuracy has an important role in preventing the increase or decrease of twenty-five percent of contracts, concluding contract supplements and preventing contractors and other problems in this area. Therefore, it is important for Metror to master the map, checklists, and indexes attached to the estimate in order to achieve this. In this article, we will deal with the basic principles of meters and estimation of metal and concrete structures.

After the approval of the design plans of phase two of the consultant, by the employer, the municipality and the organization of the engineering system, and notifying it to the consultant, the meter and estimation process begins. The initial estimate prepared by the consultant and approved by the employer, at this stage, will be attached to the project bidding documents and the contractor price offer criterion by applying the contract coefficient. It should be noted that at the end of each study and design phase (zero, one and two), the initial estimate of the same phase will be provided to the employer and the estimate of phase two of the consultant is the same as the estimate attached to the tender documents.
In fact, the meter and the initial estimation of the bridge between the end of phase two and the beginning of phase three (superior supervision) are in the consulting system. Obviously, Metror’s mastery of map reading and his technical knowledge play an important role in compiling the list of map defects and transferring it to the design unit.
By examining the final drawings of phase two and its compliance with the estimation checklists, a professional metro can, before and during the meter and estimate all the executive codes of the drawings, joinery tables, compliance of the executive details of the drawings and sections with Track joinery tables, sections and sections, identify starred items, and prepare a list of project execution items. Obviously, the accuracy and mental order of Metror at this stage will be of special importance in concluding a principled contract in accordance with the technical conditions of the project.
In construction projects and the price list, there are items of work that are not listed in the contract lists. These items and rows are starred in the final estimate booklet and are identified and defined as starred items.
If new items are concluded after the conclusion of the contract and during the project implementation in the form of contract amendment, or the percentage increase of the contract, the employer notifies the contractor that the description of the activity is not in the list attached to the contract, these items are notified after approval. By forming a commission with the participation of the employer’s representatives and the contractor, it will be reviewed and notified and will be considered as new price items in case of the contractor’s condition.
