The Custom Size Double Internal Doors Estimating Calculator estimates the materials, labour and plant required to fit double internal doors of any size. You may choose to use this option if there isn’t a suitable sized door in the Templated Double Doors.
This Estimating Calculators is linked to the specification. Therefore, many of the items required for the doors are specified from the specification you have chosen. These items deal with the structural opening and the finishes.
The combination of resources taken from the specification and the dimensional information will calculate the following items automatically:
- Frame fixings
To estimate multiple doors of the same size and specification, enter the number of doors when prompted. For example, if you were estimating two double internal doors downstairs, you would enter 2. This multiplies all materials, labour and other associated resources by two and subsequently doubles the cost.
After reviewing the door dimensions, you will be prompted to define key resources in the Estimating Calculator, namely the door and lintel. Open the Sundry Resources tab in the Estimating Calculator and click Change Resource to select a suitable door and lintel from the price book. You may need to add the door to the price book first if it is a bespoke item.
