Sonu Infratech is a family-run industrial contractor that builds and maintains the physical backbone of western India’s biggest refineries and government installations - a business born from a small partnership in Jamnagar in 2001 and now listed on the NSE. Over 26 years, it has grown into a multi-state operator with more than 500 skilled professionals, executing everything from heavy foundations and cooling towers to pipeline fabrication and plant shutdown maintenance. The recurring approach that explains the entire business is simple: own the equipment, deliver on time, and earn safety awards from clients like Reliance Industries - which keeps the repeat orders coming. # Business segments Two deeply intertwined contracting engines - civil construction and mechanical services - that serve the same industrial and government clients, often on the same sites, using the same three contracting models and the same owned fleet of equipment. ## 1. Civil construction: the foundations and structures that everything else stands on **The company digs, grades, pours and builds the site itself - roads, drains, tanks, foundations, warehouses and entire labour colonies - for refinery complexes and military bases, mostly within Gujarat.** - **A registered government contractor** - it holds a Class ‘B’ contractor licence and is registered with the Madhya Pradesh PWD and Military Engineer Services for building and road projects, which qualifies it to bid directly on public-sector tenders. - **Builds the whole site, not just one piece** - the scope spans excavation, piling, heavy foundations, RCC tanks, cooling towers, sewage treatment plants (up to 2.5 MLD), cable trenches, boundary walls, asphalt roads, and even labour colonies, so a single client can hand over an entire plot. - **Three ways to get paid** - it works on direct contracts, as a third-party subcontractor where the client supplies the raw materials, or as a subcontractor to others where it provides the materials itself and settles the balance on completion. - **Timeliness is the moat** - the company says it has never been penalised for a delayed project, which keeps cost overruns low and earns repeat orders from marquee names like Reliance Industries, Adani Group, Essar Projects and Military Engineering Services. - **Equipment owned, not hired** - its own fleet of construction machinery lets it mobilise quickly to project sites as needs arise, rather than waiting on rental availability. ## 2. Mechanical services: keeping industrial plants built, connected and running **It fabricates steel structures, erects pipelines and towers, aligns motors and pumps, and cleans vessels during shutdowns - the hands-on industrial maintenance that refineries cannot operate without.** - **Fabrication and erection under one roof** - the company fabricates and erects structural steel, trusses, purlins, rectangular tanks and pipelines, then performs hydro-testing to prove the welds hold, so the client gets a turnkey steel package. - **Keeps the giants running** - during planned shutdowns at refinery complexes, its crews clean vessels, tanks and machinery, and handle plumbing, electrification and chemical dosing system maintenance, which is recurring work tied to the client’s operating calendar. - **Safety awards open doors** - it has won multiple “Best Contractor Safety Performance Awards” from Reliance Industries (across eight different years) and an appreciation from Essar Oil for safety promotion, which signals to other large industrial clients that it can work inside hazardous live-plant environments without incident. - **Same clients, same models** - mechanical services are delivered to the same Jamnagar-region industrial base - Reliance’s refinery and SEZ divisions, Nayara Energy - using the identical three-contract structure as the civil side, so the two segments reinforce each other commercially. # Group structure and partners **A promoter-family enterprise with one newly acquired subsidiary and two sister concerns that share the same works-contract ecosystem - all operations are domestic, with no foreign entanglements.** - The company is a standalone public entity with a single wholly owned subsidiary, Arpit Techno Infra Private Limited, acquired in March 2025 for ₹3.5 crore in cash; that subsidiary is itself an infrastructure contractor covering civil construction, water supply, highways and SEZ projects. - Two related-party firms - Dev Enterprise (a proprietorship) and Micro Protect (a partnership whose partners include the Chairman & Managing Director, Whole Time Director, and Executive Director) - both provide and receive works contract services from Sonu Infratech, with transactions capped at ₹20 crore each for FY26. - The promoter group spans the founder Ramji Shrinarayan Pandey, his wife Seema, their sons Sonu and Arpitkumar, and extended family members Ketan Vallabhdas Modi and Dipti Ketan Modi, who hold key board and managerial roles. - The company has no foreign collaborations, no overseas operations, and no separate geographical reporting segment - every project is executed within India. - Its shares are listed on the NSE Emerge Platform (the SME exchange), with board and shareholder approval secured in early 2026 to migrate to the NSE Main Board.
