# Building Information Management System (BIMS) # About BIMS The BIMS is a core module of the IMIS that serves as a comprehensive database of all buildings within a municipality. It encompasses detailed information about each building maintained by the Buildings sub-module, including: Physical attributes (structure type, number of floors, and year of construction); Location details (address and geographical coordinates with building footprints; Usage and ownership (Building usage, ownership status, and associated tax codes); Utilities and services (sources of water, solid waste management services, access to sanitation, access to roads, etc.); Demographics and classifications (basic demographic data and classifications for low-income community areas). Buildings are central to IMIS, functioning as the foundational entities that interconnect all other components essential for efficient municipal service delivery. New buildings constructed post-IMIS implementation are recorded through the IMIS mobile application during the building permit process and updated for new constructions. The app, currently available for Android, captures building footprints and related data for new structures. Additional building attributes are updated during municipality’s business process in delivering various services such as sanitation assessments, sanitation service delivery and other services. However, this needs to be incorporated into the municipality’s service delivery policy. BIMS provides an interactive dashboard dedicated to building related information. This dashboard provides visual insights into building data from multiple perspectives. BIMS provides comprehensive interfaces and tools for data entry, updates, queries, and analysis. The system has a map-based integration feature that provides geospatial visualization tools for location identification. The module has data extraction tools that have capability for generating data in various formats, including CSV, Shapefiles, and KML files. BIMS offers municipalities valuable insights into Building infrastructure status, utility and service access and the critical data for planning, management and monitoring and evaluation of sanitation system and services in CWIS approach. The data maintained by BIMS helps municipality to monitor the CWIS indicators such as (i) % of LIC population with access to safe individual toilets / % of total population with access to safe individual toilets, (ii) Population with access to safe individual toilets, and (iii) Low-income community (LIC) population with access to safe individual toilets. # 9.1 Building Information Dashboard 9.1.1 Navigating to Building Information Dashboard · Open the sidebar and click on ***Building IMS*** to expand. · Select ***Building Dashboard.*** ***![](http://152.42.244.158/knowledge-product/uploads/images/gallery/2025-02/embedded-image-aiexxzzg.png)*** **Overview:** · The Building Information Dashboard provides a quick synopsis of the information maintained in this module.

Additionally, if image is already present for the building, it will not be collected during the emptying process. # 9.2.3 Add Containment to Building When the user intends to make changes to the building details (edit), by clicking on ***edit*** button, user will be given an option to Add Containment to Building. ![](http://152.42.244.158/knowledge-product/uploads/images/gallery/2025-02/embedded-image-whdmfy6y.png) · The user will then be allowed to add new containment information to existing buildings. ![](http://152.42.244.158/knowledge-product/uploads/images/gallery/2025-02/embedded-image-f5ppbiw5.png) · The form fields of the add containment are the same as the above-explained containment information in the form fields of the add building (refer to section 9.2.2 Add Building). · The user can also ***edit*** the containment information from the building edit page by simply clicking the edit button, which redirects to the edit containment page. · If the user attempts to modify the sanitation system technology and the system encounters different containment information, the system will not allow the user to change the containment details directly. The user must update the appropriate containment information (delete containment connection, edit containment type), and then modify the sanitation system technology. · When editing the building data, if a user attempts to delete the connection between the building and the containment, the following conditions must be met: 1. If the containment has application data with an "Emptying Status" of False, the connection to the building cannot be deleted. 2. If the application data is emptied, meaning the "Emptying Status" is True, the connection between the building and the containment can be deleted. In this case: § If the containment has a single connection to the building, it will be completely deleted. § If the containment has multiple connections (for example, a Septic Tank connected to both a Sewer Network and a Drain Network), only the connection to the building will be removed, and the Sewer Code or Drain Code for that containment will be nullified if the containment has outlet connections. · Additionally, new containment information/ connection can also be carried out as per the requirements. Example: If the user initially has the sanitation system set to Sewer network and needs to add containment information, the user should click the ***'Add Containment to Buildings***' button, fill out the required fields, and click ***'Save'***. This will dynamically update the Sanitation System and add the containment information. The error message below is displayed if the user attempts to add a different containment to the existing one: ![](http://152.42.244.158/knowledge-product/uploads/images/gallery/2025-02/embedded-image-7siylrvx.png) · For the deletion of either building or containment data, If the building has no connection with the containment, user can easily delete the building data, if it has the connection with the containment user must follow the below steps: o Step1: To completely remove the building data, first user must remove the connection between the building and containment. This can be accomplished by clicking on the ***“View*** ***Containments Connected to Building***” button. Upon selecting the ***details*** button, the user will be redirected to the containment details where user can proceed to delete the specific containment associated with the same building. - - - - Step 2: If the user attempts to delete building or containment data without removing the connection between the building and containment, the system will notify the user with an error message as: ![](http://152.42.244.158/knowledge-product/uploads/images/gallery/2025-02/embedded-image-tiauqacw.png) # 9.2.4 View containments connected to the Building · Click on the Building button in the Action Column. ![](http://152.42.244.158/knowledge-product/uploads/images/gallery/2025-02/embedded-image-yh39hsq7.png) - A pop-up with containments connected to the building will be displayed. ![](http://152.42.244.158/knowledge-product/uploads/images/gallery/2025-02/embedded-image-bs4qidnf.png) The user can click on the information icon (i) to view the details of the containment. # 9.3 Building Survey The **Building Survey** sub-module is dedicated to maintaining information about field surveys conducted to identify and digitize both pre-existing and new buildings in the municipality via the Building Information Collection mobile application.
