Project Description

Overview

As part of a £3million regeneration project to weir gates throughout the Thames valley, Jacksons Civils asked Marine Civil Solutions to support them with the temporary works required to provide a safe and dry working area for the Engineers replacing the gates.

Challenges

This required divers to position and fix large steel frames against the concrete structure of the weir in order to place large steel “Stop Logs”. This created a water tight barrier on both the upstream and down stream side of the radial gates which when pumped out, provided a safe working area for the Engineers.

On completion of each of the gates installation, MCS Divers relocated the temporary works to the next gate to be changed.

Quick facts

Project type: Weir Restoration

Scale: Above and below water level.

Project Details

The works consisted of;

  • Using Hydraulic and Pneumatic Drills underwater to secure the temporary steel works to the concrete.
  • Lifting and positioning of heavy steel frames.
  • Removing obstructions and Debris from the operating area of the gates using BROCO underwater cutting equipment.
  • Underwater survey of works area to help Jacksons form temporary works design.
  • Above and Below water cleaning of Weir Concrete Structure using water jet.
  • Above water temporary works Fabrication
  • Provide Jacksons with complete Diving Project Plan prior to works commencing.
