This ventilation ductwork checklist can be used and completed throughout the project and its different stages covering:
- installation &
Once the pre-functional checks have been completed, including all equipment and ancillaries related to the ventilation system, the full functional testing/commissioning can be conducted.
This checklist should be used and completed throughout the project, and its different stages, delivery, storage, installation & pre-commissioning, before the functional testing occurs.
Once the ductwork has arrived on-site, usually delivered by a transport company, and before being unloaded and accepted into storage, the following should be checked with the driver.
Any damage that is noted should be reported to the manufacturer/supplier immediately in writing supported with photographs.
|1||Supplier's consolidated delivery ticket is available, showing all equipment and ancillaries for inspection and being used to check against.|
|2||A copy of the order that was sent to the supplier is available for reference and is being used to check against|
|3||The ductwork, flexible ducting, grilles/louvers and dampers are packaged, protected, for maximum protection|
|4||The labels on the ductwork sections and technical details/sizes match the purchase order and drawing.|
|5||Delivery protection is dry|
|6||Ductwork is dry|
|7||The flanges and frames of the ductwork are undamaged|
|10||Ductwork, if ordered, is pre-insulated.|
|11||Bracketry, if ordered, is included in the delivery.|
If the ductwork is to be placed into storage on site prior to installation there will be an inspection completed checking the following.
|1||The area is internal and will not be affected by the weather.|
|2||The surface where the equipment is to be placed is level.|
|3||The equipment will be raised from the floor to allow airflow and stop the risk of water ingress.|
|4||The area is well covered and protected.|
|5||The area is well ventilated and has no risk of high humidity.|
|6||The area is clean & dust-free.|
|7||The area is secure and protected from the movement of other materials and vehicles.|
We have created this bundle to consolidate all the Equipment Pre-Commissioning and Maintenance Checklists that are available across the site.
The checklists are provided in Microsoft Word and Excel.
Storage of Ductwork
Prior to the ductwork being placed into storage, the following should be checked.
