Sheffield tudor sqaure. Bin store base (underground works) PIC 8

A base for a binstore in sheffiled that wont be seen as its finished height is below ground level. The wall itself had three elevations of which all three of them were built in 100mm dense concrete block, however two of the elevations had verangular returns built in red engineering brick. The blockwork was laid on flat (215mm) and bedded in sand and cement mortar with feb addative.(5:1). The height of the wall specified was 4 courses of blockwork (100mm) I then incorporated a rowlock bond with regards to the brickwork to ensure the bedheights would work once tied into the blockwork. I did raise concrens to the fact that the bsae itself was being built with an opening which was specified in the drawing, because in my opnion the backfilling and concrete pour would of been made very difficult by building in this fashion. after a discussion with the clerk of the works I was informed it was being built this way for a specific reason. The jointing was flush finished. All works were completed in accordance with the technical drawings and engineers markings. the wall was passed off and took 1 day to complete. All waste was cleared and recylcled in the relevant skips.
