Team up with CTSI during your early stages in the design phase, filing phase and construction process to ensure the safety and integrity of your project is achieved. CTSI will work with your construction team to complete all inspections in a timely manner with the highest level of quality control. At CTSI we are committed to strict enforcement and assurance procedures throughout the special inspection process to guarantee total client satisfaction.
