Nanjing Municipal Engineering Design and Research Institute Co., Ltd. (abbreviated as “Nanjing Municipal Engineering Institute”) is a state-owned, comprehensive municipal engineering survey, design, and full-process engineering consulting service provider with over 70 years of expertise in urban infrastructure. Its predecessor was the Nanjing Municipal Engineering Design Office, established in 1952. The institute completed its corporate reform in 2017 and is now a wholly owned subsidiary of Nanjing Urban Construction Investment Holding (Group) Co., Ltd. The enterprise positions itself to support high-quality urban development, with core businesses covering the entire technical service chain—including municipal public works (roads, bridges, tunnels, water supply, drainage, sewage treatment, utility tunnels, sponge cities, and slow-traffic systems), urban and rural planning, transportation engineering, environmental engineering, geotechnical engineering, and BIM and intelligent municipal technology applications. Leveraging key qualifications—including Class-A Comprehensive Engineering Design Qualification, Class-A Comprehensive Engineering Survey Qualification, and Class-A Credit Rating for Engineering Consulting Firms (Municipal Public Works)—as well as ISO 9001/14001/45001 management system certifications and extended qualifications for pressure pipelines, highways, and buildings, the institute possesses systematic capabilities spanning early-stage planning, survey and design, technical consulting, standards development, and intelligent implementation. It employs nearly 600 professional and technical personnel, over 40% of whom hold senior professional titles, and more than 180 are registered engineers—including one national-level Engineering Survey and Design Master and two Jiangsu Provincial Design Masters. To date, the institute has received over 100 national- and provincial/ministerial-level awards for outstanding survey and design projects and has led or participated in drafting more than 10 national and local standards, including the Technical Specification for Monitoring and Alarm Systems of Urban Utility Tunnels. Its project practice spans over 20 provinces (autonomous regions and municipalities directly under the Central Government) nationwide, with the Yangtze River Delta region as its core. It has deeply engaged in regional collaborative initiatives such as the Nanjing Metropolitan Circle and the integrated development of Nanjing-Zhenjiang-Yangzhou, undertaking government-commissioned tasks including the “14th Five-Year Plan” Special Municipal Planning and the Three-Year Action Plan for Drainage and Flood Control. The institute has also developed distinctive technical expertise in areas such as deep-bore tunnel shield design, low-carbon process technologies for reclaimed water plants, BIM-based forward design, and integration with CIM platforms. It provides multidimensional collaborative support—including full-process engineering consulting, specialized technical breakthroughs, standards research and development, and digital solutions—to local governments, urban construction investment platforms, real estate developers, and engineering EPC contractors.
