The Double Doors Glazed Estimating Calculator estimates the Materials, Labour and Plant required to fit double internal doors. There are options for estimating different widths of double doors into blockwork or studding.
This Estimating Calculator 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 Doors Glazed, you would enter 2. This multiplies all Materials, Labour and other associated Resources by two and subsequently doubles the cost.
- You should check all the pre-specified items, and in particular any items that are highlighted in red to show that they are “critical items” which are listed in the Calculated Resources tab of the Estimating Calculator.
- If the size of the opening is changed you must check the suitability of the door, frame and lintel. Carefully scrutinise the Sundry Resources tab. This section covers the more freeform aspects of the door such as the door type, furniture, lintels, sills and labour for fixing the door which are not necessarily directly linked to the dimensions you have entered.
