Mr. Mugnier's staff is professional, competent, and respectful, even accommodating a compressed timeline in our case (which may not always be possible). His structural assessment and plan for correction was conservative, but eminently sound. When we passed it on to the builders, and I asked if they thought it was the best approach, they paused, then said: "you got the opinion of the best structural engineer in the region, of course it's the best approach". Our primary inspector frequently asked, after pointing out a fault in the building, "what did Rene say about X". It is clear he holds Mr. Mugnier's judgment and opinion in high esteem. We didn't know at the time, but have since learned Mr. Mugnier is the structural engineer Boston turns to when it seeks advice on preserving architectural works. I have worked with structural engineers on two other occassions. Unfortunately, common sense, reason, and sound judgment are not always present the case in this "cover your a**" industry. Given that Mr. Mugnier's price is very competitive, and his work more thorough and comprehensible to builders responding to his advice, you have every reason to try to book with Mr. Mugnier first, if he is available.
