The City Is Seeking Up To Five (5) Consulting Firms To Provide Multi-Disciplinary Engineering Consulting Services To Support The Design And Construction Of New Siphon Infrastructure At Existing Crossings To Improve System Redundancy. Tasks Vary For Each Project And Typically Involve Field Assessments, Civil Engineering Analysis, Creation Of Engineering Reports And Drawings, Approvals, Procurement Preparation And Support, And Construction.The City Operates Multiple Wastewater Siphons And Crossings That Are Essential To Its Linear Utility Infrastructure, Enabling The Continuous Conveyance Of Wastewater Across Significant Barriers Such As Rivers And Light Rail Transit (Lrt) Corridors. To Enhance The Overall Resilience And Reliability Of The System, The City Intends To Design New Siphons/Crossings And Upgrade Or Replace Aging Infrastructure Where Necessary. This Effort Will Introduce Redundancy By Constructing Additional Siphons Alongside The Existing Ones, Reducing The Risk Of Service Interruptions In The Event Of Failures Or Maintenance Needs. As Part Of This Work, Control Structures Will Also Be Designed To Allow For The Improved Transfer Of Flow Between Siphons To Facilitate Shutdowns, Thereby Ensuring Greater Operational Flexibility And System Integrity.
