Ltd.) --- Case Study · Industrial · Piling & Civil # Tata Motors, Jamshedpur: Piling, Civil Works and I&C for 5.5 MW Solar Piling and civil works for the 5.5 MW solar plant at Tata Motors in Jamshedpur, Jharkhand. The Project ## About the Tata Motors, Jamshedpur project Tata Power issued Arrays Ingenieria the work order on 27 July 2023 for piling and civil work for the 5.5 MW plant at Tata Motors, Jamshedpur. The scope included a pre-cast boundary wall around the plant. Further orders followed through 2023 and 2024: land development, pull-out tests on the piles, gate fabrication, a temporary water supply, liaison with government offices and, from December 2023, the installation & commissioning of the 5.579 MWp plant at Jojobera Yard together with its module cleaning system. ### Our scope of work - Pile foundations (300 mm dia, 1.8 m deep) and pull-out tests - Land development and a pre-cast boundary wall - Installation & commissioning of the 5.579 MWp plant at Jojobera Yard - Module cleaning system - Gate fabrication, temporary water supply and statutory liaison ### Photos ## Project facts Capacity: **5.5 MW** Plant type: **Ground-mount, piling & civil** Location: **Jamshedpur, Jharkhand** Client: **Tata Power** Partner / programme: **Tata Motors (plant owner)** Our role: **Piling, civil works, installation & commissioning** Year: **2023-2024** ## Planning a similar project?

On Site ## Challenges and How We Handled Them ### A complete site package From land development and the boundary wall to piling, installation and liaison, almost every site trade on this plant was in our hands. ### Proving the piles Pull-out tests confirmed that the piles would hold the structures against wind uplift before installation began. ### Inside an industrial yard Working within Tata Motors' Jojobera Yard meant strict access, safety and housekeeping rules throughout. Installation & Commissioning ## What Our I&C Scope Covered The standard ground-mount installation & commissioning scope we deliver to EPC majors' specifications, after the mandatory quality and safety training and contractor safety sign-off. ### Civil works - Earth-pit chambers and covers (RCC/PCC) - Foundations for inverters, ACDB, ITB and accessories - Cable trenches - Cube tests to validate concrete strength ### Mechanical - Module mounting structure installation - Module installation and interconnection - Canopies for wall-mounted inverters and junction boxes ### DC side - String wiring from modules to inverters, tagged and identified - DC cables in conduit or tray - MC4 connectors crimped male and female - Array junction boxes ### AC side and protection - Inverters and inverter terminal boxes - AC distribution board (ACDB) - LT AC cables in trays to the approved layout - Reverse power relays installed and commissioned ### Earthing and lightning - Earth electrodes and pits - Earthing strips for structures, inverters and ACDB, including welding - Lightning arrestors ### Monitoring and cleaning - Data monitoring system (SCADA / power manager) - Module cleaning system with pump and motor - DWC pipe for RS485 communication cable ### Safety and handover - Safety lines and safety posters - Material unloading, storage under covers and care until handover - Third-party validation of tools where required - Testing, commissioning and handover [The full commissioning checklist](https://arraysingenieria.com/solar-plant-commissioning-checklist/)[Our I&C service](https://arraysingenieria.com/solar-installation-commissioning/) Related ## Services Used on This Project [Pile Foundations](https://arraysingenieria.com/service-piling/)[Civil Works & Fencing](https://arraysingenieria.com/service-civil/)[All Projects →](https://arraysingenieria.com/projects/) More Case Studies ## Other Projects by Arrays Ingenieria [Industrial · Civil Works: **DCM Textile, Hisar: Civil Works, Piling and I&C for Solar**9979 kWp (10 MW) · Hisar, HaryanaRead the case study](https://arraysingenieria.com/project-dcm-hisar-10mw-solar-civil-works/)[Utility-Scale · Civil & Fencing: **Noida International Airport (YIAPL): 14.36 MW Solar, Piling & Fencing**14.36 MW · Noida International Airport, Gautam Buddh Nagar, Uttar PradeshRead the case study](https://arraysingenieria.com/project-yiapl-14-36mw-solar-civil-fencing/)[Utility-Scale · Piling: **SECI 300 MW Solar Project, Koppal: Piling and DC Installation**300 MW solar project · Koppal, KarnatakaRead the case study](https://arraysingenieria.com/project-seci-300mw-koppal-pile-foundation/)
