Syblon Reid

Building a stronger future, one project at a time! 💪 At Syblon Reid, we’re committed to safety, quality, and excellence in every job we take on. Recently, we teamed up with Sevenson Environmental Services to enhance the waterfront parking area in Vallejo, CA. Our work included installing 60” Reinforced Concrete Pipes (RCPs), cast-in-place manholes, an outfall structure, and more. We are proud to deliver top-tier solutions, even on the toughest projects! 👷

Syblon Reid teamed up with HDR to tackle the Pyramid Dam Spillways project, working alongside the California Department of Water Resources (DWR).

Our primary tasks:

-Project Management
-Rope Access Rescue Services
-Helicopter-Supported Rock Coring
-Communications and Site Facilities Support

Syblon Reid provided SPRAT Level III and Level I certified personnel and equipment to perform rescue egress services on an as needed basis. In addition, Syblon Reid performed cleaning and conducted pressure testing of the underdrains along the spillway.

Syblon Reid also provided project management and work monitoring support in all capacities under HDR.

Syblon Reid was awarded a project for a northwest hydropower company in July 2023. The team executed detailed planning for access, demolition, drilling, grouting, concrete placement, and water management. Access was primarily through the spillway intake structure, with a scaffold stair tower and temporary guardrails ensuring safety. For the inclined tunnel section, a traveling platform supported by hydraulic winches and accessed via a heavy-duty swing stage was employed.

Drilling and grouting focused on water intrusion and reinforcing the substrate layer with cementitious and polyurethane grout injection. Demolition included radial saw cutting and selective removal of concrete using a remote-controlled hydraulic demolition machine.

The project utilized a self-consolidating concrete mix to ensure smooth application and high-quality coverage. Custom-designed radial wood forms, anchored with coil rod anchors, were used to match the tunnel’s curvature. Concrete was pumped through ports on these forms using a line pump and tremie tubes, ensuring consistent distribution and avoiding segregation. This approach, combined with advanced formwork techniques, led to successful and efficient aerator system placement.

Despite facing initial delays and a tight schedule, the project prioritized safety with zero loss-time incidents. The Contractor-designed access platform proved effective, and while drilling revealed substrate issues affecting stability, the team overcame challenges with innovative water control and demolition methods. The use of advanced concrete technology resulted in a high-quality finish and overall project success.
