I would like to know who did the planning, design, and construction drawings for the hangar. Quality control of the design and construction drawings plays a big part in the timely and successful execution of any project. Was DCK the design-build contractor. If so, their quality control comes into question. I believe the source of all the problems are due to poor quality control of the planning, design, and construction documentation, and no amount of audits will do anything to resolve the matter.
