Cost Analysis and Control of Highway Engineering Testing and Inspection

This paper discusses the cost of road engineering tests and inspections. Firstly, the object of cost analysis is clarified, including the unit price of all testing projects in highway delivery, completion acceptance, and construction control. Secondly, the basis of testing cost analysis is introduced, covering relevant laws and regulations, fee management regulations, technical standards, and norms. Next, the composition of testing costs and specific analysis methods are analyzed, including calculating direct cost fees and other costs. Finally, the costing methods of different testing projects are illustrated through examples, the main factors affecting the unit price are pointed out, and suggestions for establishing a standardized testing fee system are put forward. This paper provides theoretical support and practical guidance for the reasonable control and effective management of highway engineering testing costs.
