A new build extension to a warehouse in gloucester. the build was in imperial brick using a lime mortar (hydraulic nhl 2:5). It was build using a stretcher bond. the extension had no openings and was a straight run using expansion joints. It had 100mm cavity and used 50mm kingspan insulation board tied into a metsec framework. The expansion joints were filled with a brown coloured silicone. It was damproofed using 100m DPC. The work was protected using damp hessian to protect from element damage. all joints and beds were finished with a flush and srippled joint. The wall was acid cleaned once completed and the mortar had cured. it was built in accordance with technical drawing and in line with the method satements and risk asessments. The materials were stored in a copound area on site and delivered to the scaffolding via forklift. The materials were then taken up the scaffold using a mechanical hoist. Training was provided to all staff on the uses of the hoists. All work areas were cleaned thouroughly at the end of every working day and on completion of the task. All waste was recycled in the relevant site skips. Safety notices were clearly displayed on site to warn all persons of possible dangers relating to the given task.
