RIVER STOUR SCOUR PROTECTION SYSTEMS 24th April 2015

RIVER STOUR SCOUR PROTECTION SYSTEMS PROJECT BRIEF The installation of scour protection surrounding the cutwater section of a main pier structure spanning the river stour. This project used a pumpable micro concrete mix that was operated from a topside unit and directed into position by the diver. Prior to carrying out the works, we had to prepare the area using hydraulic underwater cutting equipment to clear a number of subsurface obstructions. RESPONSIBILITIES As director of operations and project manager I…

RIVER AVON SCOUR PROTECTION SYSTEMS 23rd April 2015

RIVER AVON SCOUR PROTECTION SYSTEMS PROJECT BRIEF The installation of eco sensitive scour protection systems around the abutment structure of a main line railway bridge spanning the River Avon. With the site being of SSSI and the land privately owned by the Royalty Fisheries, strict protocol and operating procedures had to be adhered to at all times making this project both ambitious and complex. With rock armour already in situ we were initially assigned to create a mattress formulated…

ROCK ROLL MATTRESS INSTALLATIONS 11th February 2015

ROCK ROLL MATTRESS INSTALLATIONS PROJECT BRIEF Used as a temporary scour protection measure, our brief was to install a series of rock rolls to form a rock roll mattress that was capable of resisting high velocities and shear stress loads of up to 1200 k/N which equates to around 120 ton-force within a high energy river. This system was temporary but it provided a suitable instant and flexible solution where other bioengineering techniques would be less effective. The rolls were…
