Our primary focus over the last several years has been colleges and universities. The size, building diversity and complexity of building systems demands careful attention to detail. That experience carries over into many other buildings and industries as well. Our specialty is in critical upgrades, expansions and replacements where missed items can greatly increase costs and delay construction. Various projects and customer quotes are include below.

“Our small school engaged Trinidad Engineering for a total HVAC replacement in one of our buildings. From the onset I was impressed with Mike's attention to detail and his drive to address every concern, even when it was beyond his scope of work. Mike relentlessly chased down every issue, no matter how big or small. He was constantly forthcoming with information and proactive to keep the larger team on time, on budget and on task. Mike was 110% dedicated to our project and delivered exceptional service and support.”

- Danielle Pedreira, Director of Facilities and Capital Projects, Carroll School, Lincoln, MA.

”With Trinidad Engineering, we are in great hands. Mike spends a lot of time understanding the customer requirements down to the nuts and bolts. He is very resourceful and investigates all possible designs and then provides the optimal one. As a result of his efforts, there are very few change orders and errors. Our projects are completed on-time and on-budget. Mike takes a lot of pride in his work and is focused on delivering the highest degree of quality service.”

- Cliff Migneault, Manager Engineering Services, Jones Lang LaSalle | Minuteman Park Andover, MA 01810

“Trinidad Engineering is one of the most detail-oriented firms we work with. Mike spends days, not hours, documenting each component of a system, literally down to the nuts and bolts. He uses this information to understand opportunities for efficiency upgrades in the most cost-effective way possible. He spends time understanding the maintenance required on a system and ensures that ongoing maintenance can be reduced and is safer by providing easy access to system components. For us, Mike's thoroughness has resulted in no change orders on our last three projects dating back to 2015.”

- Mark Remillard, NCARB, PMP, LEED AP, Facilities Project Manager, The Hanover Insurance Group, Worcester, MA.

“Trinidad Engineering has worked with Babson College on a hand full of mechanical projects and studies, we find them to be very thorough and very hands on through the projects. On the projects Trinidad designed for us there are no change orders which speaks volumes for the time and effort they spend on getting the scope and details right. Mike has always made himself available to Babson and their contractors when needed and assured the work as performed to the specified specs. We enjoy working with Mike and highly recommend his work to anyone who needs his type of services.”

- Andy Moutinho, Babson College, Senior Director, Operations, Facilities Management And Planning, Wellesley MA.
