Some information on the carbon footprint of the project. The building for cost and construction reasons is steel frame with concrete blockwork walls. The blocks we are using have a reduced carbon footprint however through the use of GGBS cement where possible instead of ordinary portland cement. Typically for blockwork this is 30 to 40% and will be higher in poured ‘insitu’ slabs.
Before the Christmas break the steel frame was in place, ready for installation of the precast upper floor slabs. Rising walls will start in early January.
