New Login Experience Coming!
ASCE will launch a new login experience in early 2026.
ASCE/COS 73-23, addresses development and implementation of sustainable infrastructure solutions through the entire infrastructure life cycle. It can be used for infrastructure solutions of any scale, although it is specifically not intended to unduly burden small projects.
The standard guides project leaders to encourage transformative development of the infrastructure solution from the earliest stages; consider and analyze all reasonable alternatives; and consider natural, no-construction, and constructed project solutions. It also provides life-cycle cost analysis requirements to protect and professionally steward private and public funds.
