Minimum tables, figures and equations for Structural Design Submission
Tables — at least 6
- Table — trial sections or sizes considered, with the capacity of each and the selection decision
- Table — final selected geometry for every element: dimensions, thickness, grade, spacing, elevation
- Table — ultimate limit state check summary: demand, capacity, ratio, pass or fail, governing clause
- Table — serviceability check summary: deflection, crack width, settlement, freeboard or velocity against its limit

- Equation — the sizing criterion that sets the final dimension (for example required area, depth or diameter)
- Equation — each limit state check written as demand over capacity with numbers substituted
- Equation — the factor of safety calculation for each failure mode checked
Number every table and figure (Table 4.x, Figure 4.x), caption it, and refer to it by number in your text. Number displayed equations and show the substitution with units. These counts are minimums — add whatever else your design needs.
Engineering documentation standard — required in every Chapter 4 subsection
These rules are graded on every subsection. Work that misses them is capped on technical accuracy, exhibits, codes and communication, whatever the quality of the prose.
Code and standard references
- Every requirement, factor, coefficient, limit and allowable you apply cites the governing document AND the exact section, article or sub-article number — e.g. ACI 318-19 §22.5.5.1, AISC 360-22 Chapter J, Section J3.6, AASHTO LRFD 10th Ed. Article 3.6.1.2.2, ASCE 7-22 §12.8.1, ASTM D2487, state DOT manual section, local stormwater manual chapter.
- Give the edition or year of every document the first time it appears, then use a consistent short form.
- Where a code equation is used, quote the equation number (e.g. Eq. 22.5.5.1) next to your displayed equation.
- Where you depart from a code provision, state the clause you are departing from and the engineering justification.
- List every code, standard and manual actually used in a Codes and Standards table at the start of the subsection.
Citations for statements
- Every statement of fact, value taken from elsewhere, material property, soil parameter, rainfall depth, unit cost or published method carries an in-text citation (APA) to its source.
- Field and lab data cite the report, boring log, gauge, survey file or test number and its date.
- Manufacturer data cites the product literature and revision date; software results cite the program, version and model file name.
- Uncited assertions are treated as assumptions and must appear in the assumptions table with a justification.
- Every in-text citation resolves to a full entry in the reference list.
Step-by-step calculations
- Structure every calculation the same way: (1) objective, (2) governing code clause, (3) equation in symbolic form with the equation number, (4) definition of each symbol, (5) numerical substitution, (6) result with units, (7) comparison against the limit and the pass/fail statement.
- Show the substitution line — never jump from the formula to the answer.
- Number displayed equations sequentially (Eq. 4.1, 4.2, …) and refer to them by number in the text.
- State the load or flow combination governing each calculation by name.
- Carry consistent significant figures and round only at the reported result; state the rounding convention once.
- Present repetitive element checks in a calculation table with one row per element and the same column order throughout.
Free body diagrams and figures
- Draw a separate free body diagram for each isolated element — no combined sketches standing in for several members.
- Dimension every FBD: span, depth, thickness, cover, eccentricity, embedment, slope, pipe diameter, wall height — with the dimension lines and values shown.
- Label every force, pressure, reaction and moment with its symbol, magnitude and units, and show the sign convention and coordinate axes.
- Show supports and boundary conditions explicitly (pin, roller, fixed, elastic, buoyant, hydrostatic).
- Accompany each FBD with its shear, moment, thrust, pressure or hydraulic grade diagram at the same scale reference.
- Number and caption every figure (Figure 4.x) and refer to it by number in the narrative; add a scale or north arrow to plans.
Units and notation
- Every number in text, tables, figures and equations carries its unit — no bare numbers.
- Use one unit system throughout (US customary or SI); if both appear, give the converted value in parentheses consistently.
- Check dimensional homogeneity of each equation and say so — the units of both sides must match.
- Provide a nomenclature table defining every symbol with its unit.
Checking and verification
- Every calculation is checked by an independent route — hand check against software, alternative method, order-of-magnitude estimate, or a published worked example — and the check is shown, not just claimed.
- Report demand-to-capacity ratios and factors of safety against the required values, with the source clause for each required value.
- Include a verification/checking table: item, method of check, expected, obtained, difference, accept or revise.
- Sanity-check every result (magnitude, direction, plausibility) and state the conclusion.
- Record who checked the work and on what date; flag anything still unverified as an open item.
- State limitations and the range over which the result is valid.

Section B
Engineering story
A real project situation that frames this module
A structural engineering team hits structural design submission in week 6, with the calculation package and framing drawings already promised to the owner. Compiles and submits the complete structural design package for advisor review and acceptance. The reviewer starts at the end and works backwards, and the chain breaks at calculation package organization.
The team treats independent check documentation and reviewer sign-off as a background assumption instead of an input that must be established and recorded. The result is an element loaded beyond its governing limit state, discovered only after the design of record that drawings, quantities and cost are generated from has already been built on it.
Building occupants, erection crews and the structural engineer of record carry the consequence. On this module specifically, the exposure runs through consistency check across calculations, drawings, and BOD, and the cost of correction rises every week the calculation package and framing drawings moves closer to issue.
Decisions the engineer must make
- What record establishes calculation package organization, and is that record in the project data inventory?
- Which adopted document governs this decision, and who confirmed it applies in this jurisdiction?
- What is the acceptance criterion for independent check documentation and reviewer sign-off, and was it written before the result was known?
- Is the documented procedure valid for the conditions this project actually presents?
- If the check fails, does the team revise the calculation package and framing drawings or raise a change request against the locked baseline?

Section C
Why this matters
Professional
Structural Design Submission is judged on whether an independent engineer can follow your reasoning to the same conclusion. Your complete structural design submission: calculations, drawings, and independent-check sign-off. is the evidence that they can.
Technical
Calculation package organization controls the numbers this module hands forward. Independent check documentation and reviewer sign-off determines whether those numbers remain valid once conditions change.
Safety
The failure mode this module guards against is an element loaded beyond its governing limit state. It reaches people through revision control and version history for the design record, which is why the safety check is recorded explicitly here rather than inferred from a passing strength or performance check.
Economic
The design of record that drawings, quantities and cost are generated from is priced from this work. Quantities, unit costs and schedule float all trace to calculation package organization; a late correction here is paid for as a change order, not a redline.
Environmental
Environmentally, this module fixes embodied carbon in concrete and steel, and the demolition waste of a redesign. Choosing conservatively without justification is not free — the excess shows up as material, energy and land that the project consumes for no measurable gain.
Community
Occupants who rely on the structure performing through its design life and design event inherit whatever this module decides — performance, accessibility, cost of ownership and resilience are set here, not at the ribbon-cutting.
Section D
Learning objectives
By the end of this module you will be able to:
- 1.Analyze calculation package organization, using this project's own conditions rather than a textbook case.
- 2.Explain independent check documentation and reviewer sign-off, using this project's own conditions rather than a textbook case.
- 3.Explain consistency check across calculations, drawings, and BOD, using this project's own conditions rather than a textbook case.
- 4.Interpret submission checklist against the course rubric, using this project's own conditions rather than a textbook case.
- 5.Produce complete structural design submission: calculations, drawings, and independent-check sign-off. at a standard the plan reviewer at the building department would accept without a second revision cycle.

Instructional content
Full lecture notes with figures and governing equations
Structural Design Submission: from proposal statement to engineering product
Compiles and submits the complete structural design package for advisor review and acceptance. That single sentence hides the substance of the module: calculation package organization, and independent check documentation and reviewer sign-off. Both must be established from project evidence before anything downstream is credible.
In structural engineering, this work is the input to the calculation package and framing drawings. Consistency check across calculations, drawings, and BOD — which is why this page asks you to record the source of every quantity, not just its value. The design of record that drawings, quantities and cost are generated from depends on it.
- Calculation package organization: table of contents, cross-referencing, sign-off
- Independent check documentation and reviewer sign-off
- Consistency check across calculations, drawings, and BOD
- Submission checklist against the course rubric
- Revision control and version history for the design record

Decision logic: the procedure that replaces a closed-form solution
Structural Design Submission is governed by a documented procedure rather than a single expression, so the decision logic is the deliverable: what you accept, what you reject, and on what evidence. Calculation package organization.
Write the acceptance criterion before you look at the result. Independent check documentation and reviewer sign-off — recording the criterion afterwards lets it be shaped to fit the number you happened to get.

Constraints, adopted standards and the safety case for structural design submission
No single code section governs this module, so the constraint set comes from the approved proposal, the owner's requirements and professional practice. Write those constraints down; an unwritten constraint is not enforceable at review.
The safety case is explicit here. The failure mode is an element loaded beyond its governing limit state; the people exposed are building occupants, erection crews and the structural engineer of record; the control that prevents it is revision control and version history for the design record together with an independent check by someone who did not perform the work.
- Controlling criterion for this module: calculation package organization.
- Adopted reference: confirm with the jurisdiction before you rely on it.
- Failure mode guarded: an element loaded beyond its governing limit state.
- Evidence produced: Complete structural design submission: calculations, drawings, and independent-check sign-off..

Where this method stops being valid
Every method has a domain of validity. State the range of geometry, loading, material behaviour or flow regime over which your approach holds, and state what you would do instead beyond it.
For this project, the boundary you are most likely to push is revision control and version history for the design record. If you cross it, say so in writing, bound the error, and carry the limitation into your results chapter. A disclosed limitation is professional practice; a silent extrapolation is not.

Section F
Engineering workflow
Steps
- 1. Assemble the inputs this module needs — calculation package organization; independent check documentation and reviewer sign-off — each with a unit and a source record.
- 2. Confirm which document governs, and record who verified that it applies here.
- 3. State the assumptions and the acceptance criterion for calculation package organization.
- 4. Execute the documented procedure, recording each judgement and the evidence behind it.
- 5. Test the result against consistency check across calculations, drawings, and BOD.
- 6. Audit units and run an order-of-magnitude check by hand before the number leaves your desk.
- 7. Obtain an independent check from a teammate who did not perform the work, and record their name and date.
- 8. Assemble complete structural design submission: calculations, drawings, and independent-check sign-off. and submit it to the plan reviewer at the building department for review.
Decision points
- Is every input behind calculation package organization traceable? If not — stop and collect the record.
- Does the result satisfy independent check documentation and reviewer sign-off? If not — revise the work, never the criterion.
- Would the correction change the design of record that drawings, quantities and cost are generated from? If yes — raise a change-control request before proceeding.

Common mistakes and how to avoid them
- Treating calculation package organization as a given instead of establishing it from a project record.
- Producing complete structural design submission: calculations, drawings, and independent-check sign-off. without showing how independent check documentation and reviewer sign-off was satisfied.
- Recording the outcome of this module without recording the judgement and evidence that produced it.
- Missing revision control and version history for the design record, which is exactly the path to an element loaded beyond its governing limit state.
- Designing to the average condition when the governing condition is the controlling one.
- Freezing a design before the constructability and access review that would have changed it.
- Confusing results (what the analysis produced) with conclusions (what the engineer decided).
- Ignoring constructability: a design that cannot be built safely is not a completed design.
- Omitting the safety check because the strength check passed.
Section L
Industry case study
Documented failure related to structural design submission
A constructed civil works project where this module's decision was made incorrectly or skipped.
Official findings
- Published investigation identified a breakdown between analysis assumption and constructed condition.
Field observations
- The controlling assumption was documented nowhere in the design record.
- No independent check existed at the stage where the error entered the work.
Engineering interpretation
- Interpretation below is student analysis for instructional purposes, not an official finding.
- Map the failure to a step in your own workflow and state where your process would have caught it.
Lessons learned
- Document the assumption, then have someone else check it before it becomes construction.
