The renderings are generally only sensory reference pictures, and the scheme diagram should be called the design scheme, which is more accurate and a constructive and prepared overall description of the proposed project. The construction drawing is the guiding drawing implemented by the actual instructor. It is precise and accurate, but it cannot be divorced from the design effect and scheme. In the process of implementation, due to site constraints or force majeure, adjustments and modifications are allowed with the consent of the owner. Finally, the as-built drawing is the final result of the whole construction. Honorary recommendation of Jinfeng. Jinfeng is honored to design the staff canteen and food city. It not only completed the design work, but also specially dispatched engineering supervision as supporting services to ensure the high restoration of the project.
