Project Overview
This project involved large-scale bulk earthwork, cut and fill operations, and compacted embankment formation for a 9.2 km road alignment in Panna district under the PWD MP. The project required significant terrain reshaping, including rock cutting in elevated sections and fill embankment in valley crossings. Wave Earth Infratech deployed a fleet of heavy excavation and earth-moving machinery to complete the earthwork within the contracted timeline, maintaining specified compaction densities across all embankment sections.
Scope of Work
- Site clearing and grubbing across 9.2 km alignment
- Rock cutting and hard excavation: 12,400 cum
- Soil excavation and cut fill: 55,600 cum
- Compacted embankment formation to specified density
- Subgrade preparation and trimming to formation level
- Box culvert construction (RCC): 8 nos
- Slope protection and stone pitching at critical embankment sections
- Drainage channels and cross-drainage works
Challenges & Solutions
Challenge
Unexpectedly hard basalt rock encountered in the elevated sections beyond initial estimates
Solution
Rock breaker attachment deployed on excavator; additional time factored in; final measurement revised with department approval
Challenge
Sandy fill material in valley sections failing compaction density tests
Solution
Borrow material replaced with approved laterite-soil mix; compaction process adjusted with additional passes
Challenge
Heavy rains during July-August disrupted embankment compaction work
Solution
Work rescheduled to night hours and early morning when ground was workable; polythene sheeting used to protect completed layers
