*4.2. Identify the Owner's Requirements and Analyze the Working Conditions*

According to the central and provincial government's overall plan, the project needed to be delivered before the end of August 2019. The project construction period included design and construction for a total of about 500 days. In order of decreasing importance, the owner put forward the following requirements: to be completed on time or in advance, without quality and safety accidents, reducing environmental damage, improving the ability of the project to resist potential disasters, and improving the local medical level.

The historical weather statistics show that the local area faces regular heavy rains in July, and low temperatures in November, December, January, and February. For about five months of each year, normal construction cannot be carried out and may even be completely shut down. Therefore, the actual available time of the project was about 350 days, which is only 70% of the average time. The owner of this project did not have any management capabilities or experience in similar projects. Moreover, when the project was bidding, the project's detailed design was not completed, and only the plan was made. The final needs of the owner for the project were not precise, and there was the possibility of new requirements midway. The project site was small and challenging to construct. It was close to the river, and the groundwater level was high. The environmental carrying capacity of the project site was fragile, and it was close to a natural heritage protection area, so environmental pollution needed to be minimized as much as possible.

#### *4.3. The Survey and Implementation*

The survey was sent out in May 2021. The interviewees were the owner, on-site representative of the owner, designer, contractor enterprise manager, contractor project manager, project production manager, and project supervisor who had participated in the project. The questionnaire asked respondents to review the project implementation process and propose adjustments based on their practical experience.

The basic information of the interviewees and the projects they participated in are shown in Table 2.
