This was one of the worst unprofessional experiences. Mr. Brennan Marks, Owner and Principal Engineer, was hired to create a site plan for a residential home. The first red flag should have been the misspelled words and incomplete sentences in his contract. Over the course of the contract he charged me more than 3 times his original quote. His elevation work was so amiss it cost me well over $15,000 more for a retaining wall he couldn't and didn't design properly. During initial construction he had the audacity to state he made no mistakes in the design of the site to the builder, the site contractor and the retaining wall contractor. He put things in the site plan that were not necessary because, to paraphrase, the Planning Board likes to see such things. In order to get a certificate of occupancy, the town requested a sign off from Mr. Marks on the completed site work. Mr. Marks stated he had concerns about drainage, but would sign off. A week later, he changed his mind and would not sign off. It was then I terminated his contact and hired another site engineer who reviewed the site plan, the actual site work and signed off. I went with the less expensive guy in the beginning and paid dearly for it. Mr. Marks has burned many bridges for his failure to perform. I would encourage all to steer clear.
