  • Standard Guideline for Recording and Exchanging Utility Infrastructure Data, ASCE/UESI/CI 75-22

    blue and green cover of 75-22

    Standard Guideline for Recording and Exchanging Utility Infrastructure Data, ASCE/UESI/CI 75-22, specifies essential elements for documenting the location, geometry, and feature attributes of underground and aboveground utility infrastructure, with a particular focus on enabling creation of 3D digital twins for newly installed and/or exposed utility infrastructure.

    This standard provides guidance about the collection and exchange of utility infrastructure data to support a wide range of uses including digital software applications that facilitate design and damage prevention activities. Use of the standard will ultimately lead to consistently reliable and user-friendly utility data that will facilitate better accommodation and safeguarding of utility infrastructure while expediting construction delivery with reduced risk. It supports the larger civil engineering task discipline called utility engineering (UE), which incorporates the elements affecting civil engineering projects of any kind as they relate to utilities. Utility engineering optimizes planning, design, and construction activities to control costs and mitigate risks to the project and to the public. Because the standard is not overly prescriptive, it supports both current and emerging digital project delivery standards and practices.

  • Standard Guideline for Investigating and Documenting Existing Utilities (38-22)

    blue and green cover for standard 38-22
    Standard Guideline for Investigating and Documenting Existing Utilities, ASCE/UESI/CI 38-22, endeavors to safeguard public welfare by providing guidance on performing utility investigations and documenting results in a standardized fashion. It serves as both a prescriptive standard and a performance standard. As a prescriptive standard, it provides a series of minimum actions necessary to achieve utility quality level documentation. As a performance standard, it describes the professional judgment necessary to determine the appropriate timing, sequencing, location, and scope of a utility investigative effort.

  • Wind Tunnel Testing for Buildings and Other Structures, Standard ASCE/SEI 49-21

    Standard ASCE/SEI 49-21
    Wind Tunnel Testing for Buildings and Other Structures, Standard ASCE/SEI 49-21 provides the minimum requirements for conducting and interpreting wind tunnel tests to determine wind loads on buildings and other structures. Wind tunnel tests are used to predict wind loads and responses of a structure, structural components, and cladding to a variety of wind conditions. This standard includes commentary that elaborates on the background and application of the requirements.
