Authorities in Calcutta are engaged in the upkeep of the Calcutta High Court and have actively taken various measures to maintain the building in its original beauty.
One of the aspects of the restoration work is micro-pilling in certain sections to support the structure. The importance of monitoring the effects of these actions is vital, and VDV makes it easy for all stakeholders to take required actions when necessary.
Vista Data Vision automates data generation and visualization. It is easy to use and saves a lot of manual work.
The Calcutta High Court is a heritage building that is about to complete its 150th anniversary in 2022. Some part of building structure has suffered damages over the period of time. The Authorities & consultants have decided to have online Real-time data to understand the structure’s behavior during the renovation & restoration work of the building. This project’s scope is to perform long-term structural health monitoring of designated sections of the building for a duration of five years.
Authorities & consultants have proposed various measures for restoration work, and one such activity is micro-pilling in certain sections to support the structure. The importance of monitoring the effects is vital, and the parameters to be monitored are:
• Expansion or contraction of cracks,
• Underground water pore-pressure
The sensors and Data Acquisition systems used in this project are from Geokon & Campbell Scientific.
All the Vibrating wire sensors are connected to a centralized data logger via a multiplexer through cable routing. Data is automatically pushed to the FTP server of VDV through a GSM module, i.e., a 2G/3G/4G enabled cellular modem. A DSL modem is also provided for backup in case of any mobile network failure or otherwise. Data is then uploaded to the VDV cloud for Online monitoring.
Working with VDV allows all parties to simultaneously access the same data, resulting in easy and quick consultation of the data. The automatic transfer and processing of data saves a lot of time every day, and it is error-free. There is no possibility of error(s) as the data transfer & processing, and then, the generation of pre-configured graphs is a seamless, uninterrupted automatic process without any human interference using VDV compatible data files and FTP connection.
Alarms are configured as per the client’s thresholds, and in case the limits are breached, alarm messages are sent by e-mail for stakeholders who can then take necessary actions. Data visualization in VDV presents an overview of the latest data for each location.
On the 20th of May, 2020, a Super Cyclonic storm called Amphan, caused widespread damage in Eastern India. The effects of the storm are seen in the screenshots below.
With Vista Data Vision, the client, authorities, and consultants can monitor the building entirely automatically. In addition, with automatic data generation and visualization, a lot of labor is saved.
Alarm configuration helps stakeholders stay on top of the situation and take the required steps when necessary.
