In 2022, the shortage of senior engineers and cost engineers is due to the increasingly difficult examination and the lower pass rate. Cost engineers are professionals in charge of project cost, mainly responsible for pricing, pricing and business management in project cost. What needs to be clear is that it is first of all a professional qualification, and employees must pass the unified professional qualification examination and register successfully before they can become cost engineers. In the past, there was a saying that there was a cost engineer in the industry, but now the cost engineer has been cancelled. The original cost engineer examination has also been graded into a first-class cost engineer and a second-class cost engineer. At present, it is generally believed that the second-level cost engineer has assumed the post of the original cost engineer.
