Heavy Civil Infrastructure

Engineering the foundations of large-scale development.

Complex civil construction — water infrastructure, industrial civil works and large-volume earthworks — delivered with the plant, people and precision heavy projects demand.

Rayax Infra LLP is building its Heavy Civil Infrastructure vertical to take on large-volume earthwork, water infrastructure and industrial civil construction for government missions and private industrial clients. As a new entrant to this sector, we are combining experienced technical leadership with disciplined engineering processes to execute high-precision civil works safely and reliably.

Heavy civil work is equipment- and engineering-intensive. From our first project, we are structuring our teams around geotechnical expertise, a planned investment in earthmoving and concreting plant, and structured EHS management — so clients get precision execution even as we build our own project history.

Our capabilities

Comprehensive civil infrastructure capabilities spanning water systems, irrigation, industrial facilities, mining infrastructure and site development.

Water & Urban Infrastructure

  • Water supply pipeline networks (raw water and treated water)
  • STPs and ETPs (sewage and effluent treatment plants)
  • Urban drainage and stormwater management systems
  • Elevated Service Reservoirs (ESRs) and Overhead Tanks (OHTs)
  • Water treatment plant (WTP) civil and allied works
  • Jal Jeevan Mission and AMRUT scheme execution

Irrigation & Water Resources

  • Canal lining and irrigation network construction
  • Check dams, barrages and lift-irrigation schemes
  • Flood protection and river-training works
  • Pump-house civil works and intake structures

Industrial & Mining Civil Works

  • Foundations for steel, cement and process plants
  • Heavy equipment foundations and structural civil works
  • Mining infrastructure — haul roads, benches and drainage
  • Material-handling systems and conveyor foundations
  • Industrial yard paving and internal road networks

Earthworks & Site Development

  • Bulk excavation, filling and grading
  • Ground improvement and soil stabilisation
  • Site levelling for industrial parks and SEZs
  • Retaining structures and slope protection
  • Blasting and rock excavation where required

Our project delivery process

Five stages, one accountable delivery process, from investigation and planning to testing and commissioning.

01

Geotechnical investigation

Soil testing and hydrogeological study to inform foundation and pipeline design.

02

Engineering & planning

Detailed design, quantity estimation and equipment/resource planning for large-volume works.

03

Earthwork & excavation

Bulk excavation, dewatering and ground-improvement works ahead of structural construction.

04

Structural & pipeline works

Concreting, pipe-laying, jointing and testing to design pressure and load specifications.

05

Testing & commissioning

Hydrostatic testing, structural inspection and handover with as-built documentation.

Standards

Technical standards & compliance

Every project in this vertical is engineered and executed in line with the following codes, standards and regulatory frameworks.

  • IS 3370 for water-retaining structure design
  • CPHEEO manuals for water supply and sewerage systems
  • IS 1893 & IS 456 for structural and seismic design
  • MoRTH/IS specifications for earthwork compaction and testing
  • ISO 14001-aligned environmental management practices
  • State irrigation-department and PHED technical specifications
