Why the Work Mattered

Purpose and Operating Need

The project added dedicated standby cooling capacity and system resilience through a chiller installation and tie-in.

Engineering Approach

Engineering Approach

Engineering scope: chiller coordination, pump package and piping tie-ins, cooling tower loop interfacing, field installation coordination.

Outcome & Engineering Context

Outcome and Context

Installed and tied in 250 tons of net standby cooling. Combined with the separate production-cooling project, the source records 450 tons of total net added capacity.

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.

  • Installation Contractors

    Project coordination

    Project coordination

    Mechanical and electrical installation responsibilities were assigned in the standby-chiller AFE.
