Based on the above five points, based on the powerful database function of BIM model, optimize the measurement process, and more efficiently complete the on-site high-precision measurement and setting out, precision control, on-site review and other work; At any stage of the whole life cycle of project design, construction, operation and maintenance management, the comprehensive situation of the construction site shall be completely recorded to facilitate project quality inspection and project acceptance.
β‘ Through BIM Technology, the shape, retaining structure, surrounding environment and various monitoring points of the foundation pit are modeled, the daily monitoring data are imported into the model, and the expression mode of 4D technology + deformation chromatographic cloud diagram is adopted to facilitate engineers, managers and constructors to check the deformation of the foundation pit retaining structure.
So, do you know the application value of Bim in construction survey? In the traditional construction survey work, it mainly follows the principle of taking the data as the center, usually taking the CAD plane icon recognition data as the main method for data viewing and field application, ignoring the component of 3D model (especially BIM model with accurate coordinate information and elevation information).
according to the construction drawings.
BIM Technology helps the measurement work to be efficient.
1.
The application of BIM Technology in construction survey is reflected in many aspects and stages, starting from the project construction: project construction control network layout, foundation pit settlement monitoring, process construction in place setting out, main construction survey monitoring, elevation survey transmission, building deformation monitoring, monitoring and analysis after project delivery, etc.

The main application points of BIM Technology in survey work.
According to the benchmark provided by the owner, BIM Technology is used for review, and then the survey is conducted around the foundation pit.
Construction survey scheme preparation and technical disclosure: the survey scheme is prepared based on BIM Technology, and the three-dimensional visualization advantages of BIM are applied to visually reflect the scheme intention, survey construction technology, etc., and the visual disclosure before construction survey is carried out.
The project survey control network is arranged based on BIM.
Quickly and accurately extract the data and guide the efficient operation on site.
If combined with three-dimensional laser scanning equipment, carry out on-site intelligent and efficient measurement and setting out, so as to realize the high efficiency and high precision of construction measurement.
A level-1 three-dimensional control network is created on the roads and buildings around the construction site, which is used as the primary control network for the construction of the project.
Application of foundation pit monitoring based on BIM Technology β introducing BIM Technology into foundation pit engineering monitoring can intuitively show its deformation situation and deformation trend in the process of deformation monitoring of foundation pit retaining structure.
Nowadays, the application of BIM Technology has gone deep into engineering design, construction, management and other aspects, and achieved considerable benefits.
In construction measurement, accurate data is the foundation of measurement.
The establishment of BIM model of construction survey and the establishment of BIM model with accurate coordinate elevation and appearance shape and size is the first step of application work.
2.
BIM model based on refinement and informatization can facilitate surveyors to quickly extract coordinates, elevation, size and other data, which can be applied to on-site monitoring, setting out, measurement and other work.
Generally, in the process of project application, Revit is used to establish accurate and consistent construction BIM model, site foundation pit monitoring BIM model, construction survey equipment BIM model, project control network BIM model, etc.
4.
Before the survey on the construction site, BIM technicians extract the survey data and identify the model according to the needs of the survey engineer and the created BIM model, submit the application results to the surveyors and bring them to the site for efficient construction and setting out.
