Engineer-of-record responsibility #

ILX Structures is a tool to assist qualified engineers. It does not provide engineering services, and its results are not a sealed or approved design.

• The engineer of record is solely responsible for the design, including the choice of loads, load combinations, materials, member types and details, the geotechnical values, and for confirming that the results are suitable for the project and comply with the governing building code and the project specifications.
• Every result, drawing and report produced with ILX Structures must be independently reviewed and checked by a licensed professional engineer before it is used for construction or issued to others.
• ILX Structures covers the checks and configurations described in its user manual. Whether the model represents the structure (its geometry, stiffness, supports, connections, mesh and loads) is the engineer's judgment. Conditions outside the documented scope (for example, connection design, seismic detailing beyond what the manual lists, fire, corrosion, construction stability, soil behaviour beyond the values you enter) must be addressed by the engineer separately. A check the program does not cover is marked as such and must not be read as a pass.

Accuracy #

ILX Studio, LLC tests ILX Structures, on every change, against closed-form solutions, textbook benchmarks, published design examples, code tables and hand calculations (see Verification). Even so, software can contain errors. ILX Studio, LLC makes no warranty that the results are free of errors or fit for any particular purpose, and accepts no liability for the use of the results, as set out in the Terms of Service.
