The PVCu Windows Estimating Calculator should be used to estimate the Materials, Labour and Plant required to fit PVCu windows.
This Estimating Calculator is linked to the Specification. Therefore many of the items required for the window are specified from the Specification you have chosen.
The combination of resources taken from the Specification and the dimensional information will then calculate the following items automatically:
- Frame fixings
- Window boards
To estimate multiple windows of the same size and specification, enter the number of windows when prompted. For example, if you were estimating two 600 x 1200 windows, 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 window, frame and lintel. Carefully scrutinise the Sundry Resources tab. This section covers the more freeform aspects of the window such as the window type, lintels, sills and labour for fixing the window which are not necessarily directly linked to the dimensions you have entered.
