This job was to set out the base of a garage in accordance with the technical drawings. The trenches were already dug to a depth of 1.8 m. We then had to pour the concrete for the footing. I established the finished height of the concret by measuring down from the existing dpc and transfered the height using lines and pegs. once the I set the levels using lines and pegs and poured the concerte to finish 900mm below the dpc of the existing building this allowed me to build four (900mm) courses to bring the blockwork inline with the dpc on the house. I setout the blockwork using string lines and ensured the building was square using 5-4-3 method of calculating 90 degrees.To make sure the blockwork was running through level I transfered the levels via a stright edge (spot leveling) The wall was built incorporating a cavity. The cavity was then backfilled with a semi dry lean mix of sand and cement. Wall ties were used on every course at 900mm intervals. The easterly elevation of the structure was built using red engineering brick as per the technical drawings. The blocks used were 100mm dense concrete blocks and were laid in 5:1 sand and cement mortar with feb additive.
