Learn to recognize the principles, calculated components and conclusions of the report.
Start with the basics
Check the project address, description and revision. See what drawings and data have been used and what use of the building has been adopted. Missing parts may fall outside the order.
Calculation and drawing belong together
The report substantiates the selected components. On the construction drawing states where these parts are used and how they connect. A separate profile number does not tell you how the entire construction should be carried out.
Ask for clarification if anything is unclear
Discuss unclear details with the structural engineer before ordering or building. A contractor must be able to work with the correct and coordinated documents.
First check whether the report is part of your plan
Start with the project address, description, date and revision. Then check which drawings were used as a starting point. A technically extensive report can still be part of an earlier classification. Also look at the demarcation: only becomes one beam examined or have columns, supports and foundation been included? Make a list of things that you see in your construction plan but do not find in the described assignment.
Read results together with the construction drawing
A profile name or beam size is not a complete installation job. The drawing must make it clear where the part will be located, how it will be supported and which connections have been worked out. The contractor and supplier may also need production or assembly data. Ask who develops these and who reports back changes. Have an unclear detail explained before the implementation continues based on your own interpretation.
Which standards and principles are stated?
A report should clarify the relevant design principles, including materials, loads and assessment framework. A different framework may be relevant for a renovation than for new construction. It is up to the structural engineer to determine the applicable standards and versions. It is especially important for a client that the described use corresponds to the real plan and that deviating situations are explicitly discussed.

Frequently asked questions on this topic
Can I choose a steel beam based on the span alone?
No. Loads, support, lateral support, deformation and connections are also relevant. Two openings of the same width may therefore require different solutions. Do not use a general beam table as an ordering specification for an unknown existing structure.
Is another steel profile with the same height interchangeable?
Not automatically. Profile shape, dimensions, steel type and connections influence the behavior. Have a proposed alternative assessed before ordering. Also ask whether connection details, plates and required protection need to be adjusted.
