Concord, NH Nobis Group (Nobis), a leading environmental and engineering firm in the northeast, has completed the acquisition of Richard D. Bartlett & Associates, LLC, a small land surveying company. The acquisition is part of a greater strategy for Nobis Group to enter new market sectors and add in-house land surveying services for current and future clients. 

Established in 1973, Richard D. Bartlett & Associates is one of the leading land surveying firms in New Hampshire. Serving residential, commercial, and municipal clients alike, they play an integral part in the planning and permitting process, guiding clients through local, state, and federal government agency applications and approval requirements. 

“Nobis Group has worked seamlessly with the Richard D. Bartlett Team to deliver projects to our clients,” said Nobis president and CEO Chris Adams, PE. “The two firms are aligned with our values and our focus on our clients and our employees. We’re enthusiastic about this partnership and the additional capabilities we can now bring to our clients in addition to the growth opportunities it will create for our team members.” 

Nobis Group was founded in 1988 by Nannu Nobis, PE to address the demand for high-value, integrated engineering services with a personal commitment to each client focused on efficiency, creativity, and precision. Nobis has grown into a leading northeast engineering and environmental services firm, becoming 100% employee-owned in 2021. Nobis’ offerings include environmental consulting, geotechnical engineering, and civil engineering across commercial, state/municipal, transportation, and federal sectors. 

Richard D. Bartlett leadership, Mark Sargent and Daniel Mullen, will join Nobis’ leadership as the director of project development and the director of survey services, respectively. The two firms have a strong history of collaboration, working on 250+ projects together across each market sector. The amalgamation provides clients with a single source of comprehensive services and expertise to meet all their project needs.

Bartlett said, “We’ve worked with Nobis for more than 30 years and felt that their culture and focus on employees and clients was a great fit for us. This partnership provides opportunities for the Richard D. Bartlett team members and for our clients. We are excited for what the future holds.” 

Under the terms of the deal, Richard D. Bartlett & Associates will continue business for the first year under their existing name as a division of Nobis Group. Richard D.
