Roles & contributions
  • Project Ownership

    Full lifecycle project ownership

    Owned the full project lifecycle: capital planning and prioritization, need definition, feasibility and scope development, engineering and AFE justification, procurement and vendor coordination, construction sequencing and field oversight, commissioning, turnover, and post-startup support. Connected operating requirements with technical scope, funding decisions, execution readiness, and the needs of operations and maintenance.

  • Engineering dependency

    Civil staging dependency. Planned slab stabilization, gravel access and temporary erosion controls prepare the later drainage construction.

Project ownership and delivery context

Owned the full project lifecycle: capital planning and prioritization, need definition, feasibility and scope development, engineering and AFE justification, procurement and vendor coordination, construction sequencing and field oversight, commissioning, turnover, and post-startup support. Connected operating requirements with technical scope, funding decisions, execution readiness, and the needs of operations and maintenance.

Developed the reinforced channel, debris screens, five-step weir, outlet basin and stabilization scope. Curbing, grading, landscaping and wastewater-collection interfaces were coordinated with the work. The system reduced sediment carry by more than 90 percent while providing a maintainable runoff path.
