“This was our 2nd project with obrien design + drafting. Adam is very knowledgeable of BCA requirements, a very good communicator and gives fast turn around. He provided various options then fined tuned the chosen design. The plans were accurate and detailed which made construction easy. I highly recommend their services, we couldn’t be happier.”
