## Question

Write down the unit of measurement and payment of the given items of works: i) Iron grills ii) Skirting iii) Formworks iv) Door window shutters.

## Short answer

Iron grills are measured in m² of grill area or kg by weight; skirting in running metre; formwork in m² of concrete contact surface; door and window shutters in m² of shutter area. Frames are measured separately.

## Answer

| Item | Unit of measurement | Unit of payment |
|---|---|---|
| i) Iron grills | m² of the grill area (frame included) or kg by weight | m² or kg, as per the item description |
| ii) Skirting | m (running metre), height and thickness specified | m |
| iii) Formwork | m² of the concrete surface in contact with the form | m² |
| iv) Door and window shutters | m² of shutter area, thickness specified | m² |

The measurement of the shutters is taken over the frame opening (rebate included), and the frames are measured separately in m³ or running metre.
