DeSimone Acquires Mumbai-Based ESS Detailing Services LLP

Merger expands structural detailing and Fabrication Ready Modeling capacity in India

NEW YORK, Sept. 29, 2026 /PRNewswire/ -- DeSimone Consulting Engineering, the innovative, multi-service engineering firm headquartered in New York City, today announced it has acquired Mumbai-based ESS Detailing Services LLP, a highly respected provider of structural steel detailing and modeling services. The move strengthens and unifies the DeSimone global team's ability to offer integrated engineering services, fabrication intelligence, constructability, and digital project delivery from design through fabrication and construction.

The acquisition, made through the company's India subsidiary, DeSimone Consulting Engineering India Private Limited, amplifies DeSimone's industry-leading structural detailing and Fabrication Ready Modeling (FRM) capabilities while establishing a significant platform for the expansion of DeSimone's multidisciplinary engineering services in India. The merger supports DeSimone's strategy to fortify and broaden an array of curated services—most notably FRM, and its turnkey steel design and procurement delivery system—to offer enhanced value and service to clients.

The acquisition of ESS adds nearly 200 employees to the DeSimone team, empowering the company to bring its broader multidisciplinary engineering offering firmly into the Indian market and positioning the company to respond robustly to the country's rapidly growing construction and infrastructure sectors and increased demand for sophisticated, integrated engineering solutions.

Noting the significance of the acquisition for the company and its clients, Stephen V. DeSimone, PE, Chairman and CEO of DeSimone Consulting Engineering, said, "Establishing a strong presence in India represents a critical step in achieving DeSimone's long-term, global growth strategy. Further deepening DeSimone's modeling and detailing expertise with the addition of the ESS team strengthens our ability to deliver integrated solutions and multidisciplinary engineering services to clients around the world."

ESS co-founders Arif Qureshi, Akbar Khan, and Aasim Hodekar will continue their leadership roles, now as DeSimone Principals based in India, contributing their experience and expertise to DeSimone's continued growth and expanding capabilities in the region.

Co-founder and former CEO of ESS Detailing Services, Arif Qureshi, said, "We've collaborated with DeSimone's structural detailing team as a trusted partner for many years, making our ability to work as one unified global team seamless going forward. Both ESS and DeSimone leadership share key objectives—global growth and the enhanced integration of structural engineering with Fabrication Ready Modeling. In joining forces, we bring together our teams, experience, and capabilities to deliver greater value to our clients while creating new opportunities for growth."

Ewen Dobbie, DeSimone Principal, noted: "This is an important step in the evolution of DeSimone's global Fabrication Ready Modeling and detailing business. ESS has been a trusted collaborator for many years, and we know their team, capabilities, and commitment to quality. Bringing the organizations together allows us to operate as one global team and further integrate engineering with fabrication-ready digital delivery. It gives us an excellent platform from which to build DeSimone's broader multidisciplinary engineering presence in India. Our objective is not simply to add capacity, but to create a globally integrated capability that delivers even better project outcomes for our clients."

DeSimone's Fabrication Ready Modeling service involves a unique, in-house collaboration between structural engineers and detailers who create fabrication-ready LOD 400 models during the structural design process. The firm has brought its integrated engineering and detailing services to such recent, high-profile projects as the new Bruce Springsteen Center for American Music in New Jersey, the award-winning One Times Square Redevelopment in midtown Manhattan, and the Hard Rock Hotel and Casino in New York City, among others.
