As India’s most populous state, home to over 241 million residents, Uttar Pradesh faces significant water scarcity issues that are exacerbated by low precipitation levels and an arid climate. Aligned with the country’s Jal Jeevan Mission to provide access to clean water to every rural household, L&T Construction is delivering the Uttar Pradesh tube well project to improve potable water supply in the state’s remote villages, where residents rely on uncertain water sources. The project aims to provide safe drinking water to 6.8 million rural residents through 1.7 million household connections.
THE CHALLENGE
Delivering the project required design, construction, and installation of overhead tanks (OHTs), pipelines, pumps, and solar panels to ensure energy efficiency and reliable power supply for the network.
The sheer volume of work on a limited schedule presented challenges right from the tender stage. L&T needed to analyse, design, and submit detailed bills of quantity for the 3,000 OHTs. Managing the multiple disciplines, stakeholders, resources, and logistics across the dispersed villages compounded the difficulties meeting the accelerated project schedule. L&T realised that they needed a flexible and integrated 3D BIM, structural, and hydraulic modelling solution.
THE SOLUTION
L&T utilised Bentley’s 3D BIM technology with STAAD and OpenFlows to design the distribution network. After thorough study, they came to the conclusion that going ahead with precast staging (coupler connection) with a steel container option is the most optimised. By developing 3D BIM models, L&T visually presented the construction sequence to the client, enabling them to better understand and ultimately approve the precast construction methodology.
RESULTS
- L&T saved 80% in optioneering time working in Bentley’s integrated design and analysis environment.
- The new construction methodology shortened the construction period by 90% and minimised the project’s environmental footprint.
- Working in Bentley’s collaborative BIM, structural, and hydraulic design environment resulted in saving 4,500 workforce resources per day, a time equivalent to 5.4 million resource days.
