英语翻译If rust and other defects are found on the surfaces duri

英语翻译
If rust and other defects are found on the surfaces during erection work,these portions shall be applied the suitable surface preparation and be coated immediately in accordance with the above schedule after the approval of the Engineer.
翻译：如果在安装期间发现表面有铁锈和其他瑕疵,应在获得工程师认可后对这些部分进行适当的表面处理并立即做好与之前一致的涂层.
又觉得不准确,尤其是in accordance with the above schedule ,并且after the approval of the Engineer.这个状语是只修饰coated 还是包括and之前的be applied the suitable surface preparation
