Engineer-of-record responsibility

ILX Drawings is a tool to assist qualified design professionals. It does not provide engineering or architectural services, and its drawings and calculations are not a sealed or approved design.

  • The engineer or architect of record is solely responsible for the design, including the program, the dimensions, the loads and design criteria, the soil values, the materials, members and details, the mechanical, electrical and plumbing design, and for confirming that the drawings comply with the building code adopted by the jurisdiction, its local amendments and the project's requirements.
  • Every drawing, schedule, check and calculation produced with ILX Drawings must be reviewed, completed and, where the jurisdiction requires it, sealed by a licensed professional before it is submitted for a permit or used for construction.
  • Code checks are hints that cite the code section they come from. They do not cover every requirement of the code, and a check that passes does not mean the design complies. Reference values marked [verify] have not been checked against the adopted code text and need your confirmation.
  • Simplified methods (for example the residential heating and cooling load estimate) are labeled as such. Use the full method where the project or the jurisdiction requires it.
  • Data looked up from third parties (addresses, seismic values, parcels, maps) can be incomplete or wrong; check it before you rely on it.
