The Serpentine Water Control Structure replaces a century-old structure that is seismically vulnerable and inadequate for projected sea level rise. The new watertight concrete structure spans the Serpentine River and serves several functions:

  • Flood protection for the Surrey Lowlands.
  • Tidal management - limits tidal influences within the Serpentine River.
  • Gravity drainage - allows the river to flow into Boundary Bay at low tide.
  • Pedestrian bridge with limited maintenance vehicle access, requiring adherence to bridge design codes.

What I did

I was responsible for developing the design criteria for the new structure. My work involved reviewing and synthesizing diverse technical documentation to establish a foundation for the design phases.

  • Reviewed the detailed Request for Proposal (RFP) to understand the client’s objectives and requirements.
  • Examined the building code, focusing on provisions applicable to water control structures.
  • Reviewed CSA S6 Canadian Highway Bridge Design Code for the pedestrian bridge requirements.
  • Analyzed technical reports from geotechnical, process mechanical, and electrical disciplines to identify structural implications and integration needs.
  • Synthesized findings into a structured design criteria document that served as the guide for both the client and the project team.

Deliverables

  • A design criteria document that was accepted by the client and the project team.
  • Early identification of potential conflicts between design aspects and regulatory requirements.
  • A clear technical and regulatory basis for the detailed design phase.
