Underground Utility and Structure Mapping near Brick Minar and Jhulta Minar, Ahmedabad Railway Station for RLDA (Statutoru Authority, Under the Indian Ministry of Railways) in Collaboration whith IIT Gandhinagar
| Scope of Work: | GPR investigation to map underground utilities and archaeological structures up to depth of 8 m. | ||
|---|---|---|---|
| Location: | Ahmedabad Railway Station, Gujarat. | ||
| Client: | RLDA. | ||
| Equipment: | GSSI SIR 3000 and SIR 4000 equipped with 100 MHz, 200MHz and 400 MHz center frequency antennas. | ||
| Challenges: | Machine movement due to undulations, data collection is several small patch, local people and Rail movement. | ||
| Summary: | This project includes the study of the subsurface in surrounding areas of two archaeological structures, Brick Minar and Jhulta Minar under the scheme of the redevelopment of Ahmedabad Railway station. This study attempted to explore the potential locations containing any buried archaeological features corresponding to different eras and underground utilities up to the depth of around 8 m using the non-destructive technology, Ground Penetrating Radar (GPR). The objective of the survey is to locate possible buried archaeological structures related to historical buildings or ascertain other remnants of previous ages and underground utilities. The output results of this study helped to plan and optimize the further excavation at specific locations as this can minimize the risk of damaging an artifact or structure of archaeological importance and underground pipes, cable, etc. Considering the client's requirement, and available information about the existing features, the depth of exploration is 8 m. Therefore, the survey has been executed using 100 MHz, 200 MHz, and 400 MHz centre frequency antennas equipped with SIR 4000 and SIR 3000 GPR system to cover the expected depth with a fair resolution. | ||
