Due to the large volume of this fly ash storage project being a heavily loaded storage structure, settlement observation is required. To carry out the settlement observation work more accurately and objectively, it is recommended that the construction unit entrust a unit with professional survey qualifications to conduct the observations and integrate them into the entire factory's elevation monitoring network.

Due to the large-scale fly ash storage project's nature as a mass-bearing silo, settlement observations should be conducted. To accurately and objectively implement the settlement observation, it is recommended that the contractor entrust a unit with professional surveying qualifications to carry out the work and integrate it into the entire factory's elevation monitoring network.

Based on the actual site conditions, for convenience of observation, the settlement point is installed on the frame at +1m above the circular foundation benchmark elevation, with an elevation value of +0.50m. The position of the observation point is determined according to the design drawings provided by the design unit.
