Often this person is a professional engineer engaged by a supplier or fabricator. Usually the delegated design is required to be shown on shop drawings bearing the professional seal and signature of the professional engineer who did the design.  \nDelegated design is commonly used in relation to shoring, stairs, guards, handrails, wood trusses, fire sprinkler systems, curtain walls or glazing for example.  \nMunicipalities are increasingly requesting shop drawings showing the delegated design be submitted before they will issue a building permit. At first glance, this can be disruptive of the normal processes and project work flow. Unless permit application occurs well after contract award (possibly delaying the start of construction), it is unlikely that suppliers or fabricators have been selected. Most suppliers and fabricators are unwilling to commit to the expense of producing shop drawings for a project that they have not been awarded. Further, comments received from the AHJs may require design or contract changes which would require the shop drawings to be redone.  \nSeveral building departments have been contacted to gain an understanding of the issues with delegated design from their perspective. The common thread is that the authority reviews the drawings for compliance with the building code and has a responsibility to confirm that the building has been designed to be in compliance with the building code.  \nIn some cases, there is not sufficient information on the permit drawings to determine if the design is in compliance with the building code. A simple note that the delegated design is to meet code and that shop drawings are to be submitted is not sufficient. To determine that the design is in conformance with the building code plans examiners may request the shop drawings up front. The issuance of the permit may be made subject to the submission of acceptable shop drawings for review by the authorities prior to construction.  \nSuggested Procedure  \nFor building elements relying on delegated design, sufficient information should be provided on the permit set to allow the authority reviewing the drawings to determine that the design intent meets the applicable code requirements. In most cases, it should only be the structurally engineered aspects of the design which are delegated. An exception to this is the hydraulic design of sprinkler systems.  \nThe delegation of design does not change the architect’s contractual responsibilities to coordinate the work of the consultants, including any scope which is subject to delegation. The dimensional, relational and connection information required to demonstrate code compliance should be provided on the architectural drawings.  \nIn the case of delegated design, the architectural specifications should include the requirement for shop drawings bearing a professional engineer’s seal to be submitted for review by both the consultants and the AHJs prior to any related construction  \nFor example,","cbCainaRmsyrocV7","https://ap.wps.com/l/cbCainaRmsyrocV7","pdf",212230,"English","# Summary\n# Background\n# Suggested Procedure\n# Disclaimer","[{\"question\":\"What is delegated design, and who typically performs it?\",\"answer\":\"Delegated design defers specific detailed design aspects to a specialist for the deferred work, often a professional engineer engaged by a supplier or fabricator.
