Veit Crew Installing Concrete Precast Weir Segments at Castle Rock Veit Crew Installing Concrete Precast Weir Segments at Castle Rock

Marine

Project Overview

Veit’s dive team completed a critical marine project at the Castle Rock Powerhouse.  The project entailed installing 125 concrete precast weir segments downstream of the powerhouse discharge.  The purpose of these weir segments is to better dissipate flow rate from and preserve the river bottom of the hydroelectric facility.  Through the efforts of management teams and their excellent planning, these segments were able to be installed as designed, while staying on schedule and doing so without any injuries.  The dive team went above and beyond to work with the facility owner, general contractor and crew members to reduce any associated risk and improve performance.

Challenges We Solved

01.
Tight Tolerances
Weighing in excess of 3000lbs each, these concrete weir segments had to be carefully positioned as each one was designed with only 1” of clearance tolerance.
02.
Poor Visibility
Underwater conditions made work difficult for the divers as they could not see more than 3ft in any direction while diving. Careful planning and constant communication was necessary during every dive to ensure worker safety and to avoid any accidents.
03.
Crane Clearances
Lifting the hefty 1.5-ton weir blocks required the use of a lattice boom crane, and lack of accessibility meant it had to be on a floating barge platform. Throughout this project, the crane was frequently positioned underneath high voltage power lines. Crews continually monitored boom height and used spotters to avoid striking the lines.
