3.9 Best Practices for Structural Drawings General Best Practices The Structural Engineer, as a member of the Design Team has the primary role of developing the structural system necessary to meet the needs of the architectural design as well as the code required performance of the gravity and seismic systems, dictated by seismic design category and the site specific conditions. Most project design start with the analysis of the geotechnical site conditions and the selection of the primary structural systems, which will determine the framework of the building, and become the supporting members for the architectural and MEP systems. Although much of the structural engineer’s work is determined by the site conditions and code design requirements for seismic and gravity restraint, it is key to the success of the design process that the structural system be highly coordinated with mechanical HVAC and piping as well as the architectural systems of the exterior cladding and interior partitioning. It is essential that the Structure Engineer have early involvement in the planning process and contribute to the Design Team solutions to the building that respond to Code and inform the Architect and MEP engineers what considerations need to be made in developing their designs. Early activities may include: • Compile site specific conditions as early as possible like existing buildings, survey of grades, geo-hazard and geotechnical reports. • Identify important project objectives like open spaces, long spans, floor plan flexibility, • Develop structural schematic design alternatives based on early planning, site conditions, and project objectives • Select optimum design alternative and validate major structural systems using approximate analytical methods • Establish, quantify, and validate all sources of structural loading. • Identify all conditions requiring alternate design procedures and / or special testing of structural elements • Coordination with ALL design disciplines for structural member penetrations, depths, support, bracing, anchorage, and other structural considerations. • Establish all elements of the Designated Seismic System • Define structural engineering design requirements for building system components (non-structural) Working with OSHPD Structural (OSHPD Best Practices) Page 46 DRAFT FINAL, Sept. 2011
Early in the design process, it is also essential to start communicating with OSHPD staff to identify any special issues and approaches necessary for the structural design to consider when developing the basis of design for seismic and gravity systems. For larger, new hospital projects, this might occur at a general kick-off meeting with OSHPD review staff to introduce the project and nature of the structural systems. For smaller projects, or renovations of existing hospitals, this might be a short meeting with structural reviewers to review special aspects of the project which have structural issues. • Identify all conditions requiring alternate design procedures and / or special testing of structural elements. • Identify and validate design methodologies with OSHPD for structures with special design considerations. As the building design progresses and structural documents are developed in coordination with the Architect and MEP Engineers, the Structural Engineer should be considering the following: • Complete analysis and design of major structural systems, members, and connections • Identify, map, and analytically validate all building load paths • Establish all member and connection capacities • Establish an appropriate analysis and design methodology • Identify structural requirements for the Test, Inspection, and Observation program • Regular internal peer review of structural systems throughout the design process Organization and Approach Overall quality of the design and the documents for the structural drawings will depend on having the right individuals with the right experience, as well as following established engineering processes for documentation and team coordination. • Only assign design professionals to the project with California hospital design experience • Establish early involvement of structural engineering expertise. • Maintain the same engineering resources throughout the project design, OSHPD plan review, and construction. • Apply design drawing standards for quality assurance. • Validate computer generated results by manual hand calculations at critical locations.. • Cross coordinate structural plans, sections, details, notes, and specifications. • Coordinate with other project design professionals to confirm geometric compatibility of AMPE systems components. • Maintain Structural Engineer of Record involvement throughout the project until construction is complete.
