Description
Technical Field

[0002] As we all know, the direct meaning of engineering cost is the construction price of the project. The three elements of engineering cost are quantity, price and fee. "Quantity" is the primary task of engineering cost. Cost engineers need to measure a series of data. The measuring ruler is an indispensable tool. Nowadays, with the development of the construction industry, people pay more and more attention to the saving of construction cost materials. Through advance measurement and planning, the best material usage can be calculated to reduce material waste and thus reduce the cost of the project. Therefore, the use of measuring rulers is becoming more and more important. Traditional measuring rulers are generally measured with rulers. In order to facilitate carrying, the length of the measuring ruler will not be too long. If the object to be measured is long, the measuring ruler needs to be used multiple times to measure the length of the object to be measured.
