“We at Roth & Seelen, Inc., have worked with Golam Mustafa and Pristine Engineers on a number of projects. Pristine has provided HVAC, Plumbing, Fire Protection, and Electrical/Alarm engineering services to us on projects ranging in size and type from smaller commercial office fit-up projects, to a special needs school 86,000 SF in area. Pristine’s services have included all phases of engineering work, from design through construction documents and construction administration. They have been a pleasure to work with, and their professional and thorough approach to their work has helped us to deliver high quality design services to our clients. Golam Mustafa provides principal-level involvement in all phases of the projects.

I would not hesitate to work with Pristine Engineers in the future, and I recommend Pristine to others seeking building Mechanical/Electrical engineering services.”

“We have employed Pristine Engineers to provide MEP design for a complicated project which required unique design coordination details in order to maintain existing operations during new construction. They were most cooperative during all aspects of the project (permitting, design and construction) which contributed a successful project.”

“Golam Mustafa was the mechanical department manager for Jacobs, Edwards & Kelcey (JEK) at their Congress Street office in Boston, MA. As a senior project manager at JEK I worked with his department which included HVAC, Plumbing and Fire Protection engineers on numerous occasions.  I found Golam to be conscientious and an excellent engineer whose wealth of experience resulted in practical cost conscious solutions to design problems. As an HVAC engineer on one of my Beacon Hill projects we were required to obtain approvals from the the Beacon Hill Architectural Commission. After many public hearings and the production of a detailed report authored by Golam we were successful in satisfying the commission that Golam’s design was the only practical solution to the problem. During this time Golam exhibited excellent owner interface skills. I would not hesitate in recommending Golam and Pristine Engineers as lead engineers or as part of a multi-discipline A/E team for any project that I was involved with.”

“I have been working with Golam Mustafa for the last 10 years or so,  Not only he is a good friend, but he is an excellent engineer.  Our office, TLCR Architecture, is an open practice but, we have been designing a lot of public schools in New England for many years, lately, Golam has been our principal mechanical engineer.  Among the several dozen recent projects, including feasibility studies, renovations and new buildings, he worked with us at the Harrington and Fiske Elementary Schools, in Lexington Massachusetts, These two schools use geothermal systems for their heating and air conditioning, providing the Town with savings around 35%/year in their energy consumption costs.  The back-up gas heating systems have been used solely for testing during the last three years!

I have found Golam to be a very responsible professional with clear dedication to excellent design, meeting schedules and concern with available budgets.  These attributes, coupled with his cooperative and creative spirit has made him a very valuable consultant member of our design team.  I do not hesitate to highly recommend Golam Mustafa and Pristine Engineering.”

a service provider’s perspective, Golam has always supported the highest
standards for the industry and has always been very responsive. He is a true
problem solver and any prospective client would be well-served by Golam’s
commitment to first-class service, technical leadership and astuteness. I
wish Golam the best in his new venture with Pristine Engineers, Inc. and  I am
fully confident he will provide value to the market through differentiation
and responsive high quality engineering in the most demanding situations.”

“It was pleasure working with Golam. He is a very detailed oriented person.
He manages his projects very well and continues to maintain relationships
with past clients. After the project is completed he goes to see the
progress by himself. He is well liked by his peers and clients. His
technical capabilities are outstanding. He is a team player. I would love to
work with him in future opportunities. I wish him all the best in his
career and personal life as well.”
