Codes & Standards

      • ASCE Standards provide technical guidelines for promoting safety, reliability, productivity, and efficiency in civil engineering. Many of our standards are referenced by model building codes and adopted by state and local jurisdiction. They also provide guidance for design projects around the world.

        Standards Development Process

        Accredited by the American National Standards Institute (ANSI), ASCE has a rigorous and formal process overseen by the Codes and Standards Committee (CSC). Standards are created or updated by a balanced, volunteer standards committee, followed by a public review period.

        All standards are updated or reaffirmed at least every 5 years. ASCE's standards program is regularly audited to ensure compliance with the ASCE Rules for Standards Committees and that it is consistent with ANSI requirements.

        Anyone can submit a proposal to change or create a standard. Please contact  Codes and Standards Director for proposal form.

        Step 1: Proposal

        • Proposal for New Standards Activity
        • Propose new or change to existing standard
        • Propose an amendment to an ASCE Standard

        Step 2: Balloting

        The committee shapes a proposal into a standard through meetings and ballots. The volunteers writing standards are experts with knowledge and expertise in the particular field.

        Upcoming Meetings

        ASCE rules require a 30 day advance meeting announcement.  Please click here to submit a meeting date and time.

        Step 3: Public Comment

        Public comment- In accordance with ASCE Rules for Standards Committees, ASCE conducts a minimum 45-day Public Comment period on any new, revised, or reaffirmed standard. Any individual who is not a member of a Committee shall be permitted to participate in a public comment period on a standard. Comments submitted after the close of the public comment period will, at the discretion of the chair, be resolved during the current public comment period or will be considered during the next revision cycle of the standard.
