### PHASE 3--Application for the 3D Simulation of the Maintenance Management of the Building Facilities
#### 3.3.3 Step 3--Develop Pre-Maintenance Activities  
Among the previous activities to be carried out are _corrective maintenance_ and the corresponding _work orders_. The following section explains how to manage them using the _YouBIM_ CMMS. Asset Management (Types)  
Assets are all the elements that make up the structure where maintenance is to be performed, from a screw that requires a predictive operation to an industrial electrical panel. With the \"filters\" tool in the CMMS, the assets can be browsed through, either by listing them (Figure 20a) or by viewing them in a 3D format (Figure 20b). When an asset is selected in the model for consultation, its properties can be accessed. In addition to being highlighted, a pop-up appears displaying preliminary information associated with the asset. Furthermore, the pop-up allows the information to be expanded in the \"details\" section, enabling the generation of _Work Orders_ (in the \"WO\" section--OT in Spanish) or providing access to the asset's location in the 2D drawings (Figure 21). Figure 19: **(a)** The 3D navigation capabilities for the exterior of the Civil Engineering School model within the CMMS YouBIM environment. This feature enables users to interactively explore the building’s exterior, examining architectural features and surrounding elements. **(b)** A 3D visualization of assets within the CMMS YouBIM model. This feature offers an interactive representation of various assets, enabling users to examine their locations and interrelationships within the building. Manage Asset Details  
The asset details are managed through the \"view details\" option, which displays a pop-up containing all the information associated with the asset. In addition, it allows linking or filling in information that has not yet been updated or included, such as \"asset data\", \"type\" data that provide further information on the asset, data on the system to which it belongs, work orders generated, associated documents or inclusion of new documents, etc. (Figure 22). Figure 21: Selection and visualization of an individual asset in the men’s restroom on the first floor of the Civil Engineering School within the 3D model. This feature allows users to view asset details, including their placement and condition within the facility.

This filtering feature enables users to efficiently organize and manage various assets, facilitating quick and effective access to relevant data for maintenance and operational needs.

This view specifically highlights devices located in the bathroom complex on the first floor of the Civil Engineering School, enabling an interactive and detailed exploration of assets within this space. Work Orders (WO)  
The software was configured to classify the work orders that are created according to the case, in the group of preventive, corrective, and predictive maintenance (Figure 23). In this way, when working with the work orders, the manager will be able to classify them quickly. The labels were also previously configured. Labels are a secondary way of sorting by assigning a color marking directly on the asset. Work orders can be managed through listings (Figure 24a), scheduling (automatically generated in a calendar view with a monthly layout) (Figure 24b), and email notifications (Figure 25). This scheduling and notifications can be followed both from the CMMS itself and from the personal or institutional calendar associated with the account of the stakeholder in charge of the WO. Thus, every modification that is made to the WO will
