In some cases initial inspections are in progress, or have recently been completed, therefore, no additional inspections are required.

Midway Coating Contractor, Field finish coating work has been overview inspected by Ceco OAD. The overview inspection consists of a check of ambient conditions, inspection of surface preparation, batch mixing, '

film thickness measurements and visual examination of finich coating and stored materials. Due to the comprehensiveness of overview inspections no additional action is required.
