On the one hand, to improve the market access system of survey enterprises, besides the strict examination of corresponding technicians, it should also include the strict examination of equipment and quality management system, so as to eliminate those survey enterprises with insufficient technicians, backward technical equipment and chaotic quality management. On the other hand, it is necessary to strengthen the management of scientific and technological input of survey enterprises from the system and regulations. For example, the administrative department in charge of construction industry should guide and encourage enterprises to increase investment in science and technology, strengthen technical reserves and technological innovation from systems and regulations. Only by relying on scientific and technological progress and updating technical equipment can we improve the technical level and content of survey enterprises and improve the quality of survey.

(2) Strengthen the management of the construction unit.

On the one hand, it is necessary to strengthen the bidding behavior of the construction unit. The standard of survey fee is too low, and there is no economic benefit. The survey unit will not do as required, because no survey unit will do business at a loss. Therefore, the administrative department in charge of industry should stipulate that the lowest price of survey fee shall not be lower than the national charging standard according to the regional characteristics. On the other hand, strengthen the integrity education of the construction unit, and try to avoid defaulting on the project payment.

(3) Surveyors should strengthen self-improvement and self-cultivation.

The main objects of investigation are all kinds of rock and soil. The variety, diversity and complexity of rock and soil determine that the objects of investigation are actually heterosexual and have different characteristics. In the process of exploration, we should constantly reflect and summarize, improve personal professionalism and improve the accuracy of judgment in the process of exploration.

(4) Establish an investigation and supervision system.

The implementation of inspection and supervision system can monitor the whole process from the aspects of inspection and supervision scheme, field work, inspection results and participation in tank inspection. This can prevent the unreasonable arrangement of investigation workload, especially the false record of original data and the fiction of original data. It can also monitor whether the technicians' sampling conforms to the specifications and whether the in-situ test experiment is done as required. It is particularly important to establish and improve the investigation and supervision system at present.
