SANDSTONE ROCK ARMOUR REMOVAL

SANDSTONE ROCK ARMOUR REMOVAL

PROJECT BRIEF To locate and remove a number of 5 tonne sandstone boulders so that the site contractor could complete the installation of a sheet pile retaining wall.  On completion of piling works, rock armour was to be reinstated to provide a suitable means of scour protection.
RESPONSIBILITIES I was responsible for interpreting the drawings provided by the client and compiling the dive management system which included everything from the sequence of works to be adopted to the comprehensive risk assessments to be evaluated.
CLIENT MMC Diving Services | Raymond Brown Construction Ltd
CHALLENGES Lifting operations inherently pose the potential for high risk situations especially whilst working on the seaward elevation of a coastal defence system.  Due to the size and irregularity of each boulder caution had to be taken both in fitting the lifting strops and retaining them in situ during the lifting process.  For this purpose additional machinery on site consisted of an air lift pump and a Spitznel Hydraulic Drill.  There were many other factors for consideration that I included within the comprehensive risk assessment.
