The Lintels Below Ground Estimating Calculator estimates the materials, labour and plant required to install lintels below ground for garage conversions or for bridging across services trenches.
To estimate a lintel, start by selecting a lintel from the Lintel Specifier. Review the dimensional information for the lintel, paying particular attention to the labour required to break out any slab and excavate for the lintels.
This Estimating Calculator is linked to the specification.
The combination of information taken from the specification and the dimensions you enter will be used to calculate the following items:
- Engineering bricks
- Heave protection board
- Coursing blocks
- Blockwork and brickwork
- Plus the labour associated with the above
