"DCD is an asset to any project and any mechanical subcontractor. As a BIM/VDC consultant working with a large variety of mechanical subcontractors and MEP modelers, we have worked with DCD on countless jobs ranging in complexity, size, and BIM/VDC coordination requirements. Each time, Bil/DCD have gone above and beyond each time to be a team player, find workable solutions for all parties, and meet even the toughest project deadlines. Bil has even jumped into the middle of projects and worked long and late to get caught up and make the project a success. His communication and dedication each time are commendable. DCD consistently produces the cleanest, field-friendly deliverables from install drawings and sleeve layout drawings, to CMU/specialty wall penetration drawings, and more. MB BIM Solutions would recommend Bil and DCD time and time again."
