We have used Cornerstone Engineering for structural studies of our older school buildings and they are extremely responsive to the client’s need regardless of project size. They involve the client in the design process by discussing available options to provide guidance in decision-making. We appreciate their expertise in the use of fiberglass reinforcement for non-invasive structural repair. The work is complex, but Cornerstone Engineering has performed professionally and in a timely manner; helping us resolve many of our building issues.
