For more than 27 years, SINGH + Associates has been meeting and exceeding our clients’ expectations for high quality planning, design, and engineering services delivered with care and attention. But capabilities alone don’t begin to describe the underlying culture and orientation to our business. The core values we uphold – INTEGRITY, EQUALITY, GRATITUDE, and KINDNESS – have served as a foundation to our practice from its inception because of the dynamic force of our founder, S. Singh Rikhiraj, PE.


Mr. Rikhiraj left his wife and two young daughters in his native Punjab, India to pursue a passion for civil engineering and create a better life for his family. In 1970, he immigrated to Canada where he completed a Bachelor’s degree in Engineering from the University of Ottawa and began work at the Ontario Ministry of Natural Resources. In 1982, he moved his family to the Chicago area to expand on his passion and put down roots for what eventually would become SINGH + Associates.

In 1992, at the age of 50, Mr. Rikhiraj established our company to harness his entrepreneurial spirit and provide cutting edge and collaborative civil engineering services for public infrastructure projects in a highly competitive marketplace. Through his driving determination and commitment to core values, he gathered a team of quality professionals with a broad spectrum of design and engineering capabilities who embraced the same commitment to strong business ethics and client satisfaction.

In 2019, Harvind K. Singh assumed the lead of SINGH + Associates as President and Owner. Ms. Singh joined SINGH & Associates in 1999 and was the driving force behind the firm’s growth and development – advancing the corporate structure and integrating effective management practices, policies, and procedures. She is dedicated to Mr. Singh’s legacy of a business culture centered in Integrity and Kindness while advancing the development of SINGH’s Prime Consultant engineering capabilities as well as SINGH’s expansion into new geographic markets and service sectors.

Today, SINGH + Associates retains more than 40 professionals who specialize in roadway lighting, Intelligent Transportation Systems (ITS), and transportation as well as offering expertise in civil, MEP|FP, and CM services.
