SCV Water Contracts LEE + RO to Design Pipelines for Sierra Highway Bridge

LEE + RO to address constraints, anticipated problems, and potential construction issues.

The City of Santa Clarita is currently designing their Sierra Highway Bridge Widening project. As part of construction of that project, the southbound bridge will be reconstructed. The Santa Clarita Valley Water Agency (Client) is constructing two new pipelines (one 20” potable water pipe and one 20” recycled water pipe) inside two new bridge cells. Each bridge cell will contain one new pipeline.

1. The potable water pipe-line work will include a pipeline casing, spacers, the carrier pipeline, pipeline supports and appurtenances, as-needed vaults, and the connections to the existing pipelines on the North and South sides of the bridge.
2. The recycled water pipeline work will include a pipeline casing, spacers, the carrier pipeline, pipeline supports and appurtenances, as-needed vaults, and capped-out stub outs for future connections.

Situation

Water pipelines are one of the “high-risk” utilities by many bridge agencies since its failure could damage the structure, endanger the public or create a traffic hazard. The advantage of using a host bridge in an established corridor over building a dedicated crossing provides greater pipe alignment, lower pipeline cost, reduced environmental impact, and simplified and faster permitting process.

The Project execution will be completed over three months and services includes:

• Project Management and Meetings
• Preliminary Design Investigation
• 75% Plans, Specs, And Estimates
• 100% Plans, Specs, And Estimates
• Bid Documents
