What Oriental Structural Engineers does

Oriental Structural Engineers Private Limited (OSE) is an Indian infrastructure construction company founded in 1971 and headquartered in New Delhi. It specializes in rigid and flexible pavement engineering for highways, expressways, and airfields, and operates three primary business verticals: EPC (Engineering, Procurement and Construction) contracts, BOT (Build-Operate-Transfer) toll and annuity highway assets, and commercial coal mining. Over five decades OSE has constructed more than 8,308 lane km of highway and completed pavement works at 39 Indian airports including challenging island locations such as Car Nicobar and Agatti.

The company generates revenue through a mix of project-based EPC contracts, long-duration BOT toll and annuity concessions with NHAI, and mining services contracts with government coal companies (BCCL and MCL). Its core technology is heavy civil-engineering execution supported by an in-house plant and equipment fleet valued at over Rs 8 billion, a centralized 5-acre maintenance workshop in Gurgaon, and a deep technical bench of 180+ graduate engineers and 210 diploma holders with up to 45 years of individual experience. Marquee technical accomplishments include India's first F1 racetrack at Buddh International Circuit (delivered in 18 months) and 2.5 million tonnes of concrete produced in under a year for the Yamuna Expressway.

OSE monetizes completed road assets through Oriental InfraTrust, an InvIT established in June 2019 that holds approximately 631 km of operational roads and is backed by multilateral investors including IFC, AIIB, and DEG. OSE is part of Bakshi Enterprises, a Delhi-based industrial group with Rs 55 billion in annual turnover. Its primary customers are government agencies (NHAI, MoRTH, NHIDCL, Airports Authority of India, state PWDs, UPEIDA, BCCL, MCL), with select private-sector infrastructure developers (IRB, Tata Realty, Jaiprakash Associates, GMR) accounting for a smaller share of revenue. Pricing is determined through competitive bidding on government tenders rather than published price lists.
