Write This Requirement Properly

B2 Writing the Spec
About this lesson ▾

A note on a drawing is not a description. It is an instrument that binds someone to do something. Before we teach how, we find out how you write one now.

Warm-up · 5 min

How do you write notes now?

Answer honestly — nobody is marking this:

  • When you add a note to a drawing, do you think it in Portuguese first?
  • Have you ever copied a note from an older set because you were not sure how to word a new one?
  • Has a contractor ever done something different from what a note of yours intended?

The third question is the one this unit exists for.

Teacher note The copying admission is common and is not laziness — it is a sound instinct (spec English is formulaic and reuse is correct practice). Frame it that way. The problem is only that copying without control breaks the moment a new requirement has no template.

Input & Noticing · 10 min

Two versions of the same requirement

One of these is enforceable. The other is a suggestion.

Same intention, different instrument

VersionWhat it actually does
The conductors need to be the right size — check the code table.Describes a concern. Binds nobody. If the wrong size goes in, this sentence does not establish that anyone failed.
Conductors shall be sized per CEC Table 310.16 and protected in accordance with CEC Article 240.Creates an obligation, names the standard, and is checkable against a specific table. If the wrong size goes in, this sentence is what proves it.

The second is from your own Wooster Avenue set. Notice four things it does that the first does not:

  1. Names the thing, not the person. Conductors, not you or the electrician.
  2. Uses shall. Not need to be, not should, not will.
  3. Cites a specific authority. Not the code table — CEC Table 310.16.
  4. Covers a second requirement in the same breath without repeating the subject.

Focus on Form · 8 min

What spec English is for

A specification note is read by four different people, and it has to survive all of them:

  • the contractor, who needs to know exactly what to build;
  • the plan checker, who needs to confirm it meets code;
  • the inspector, who checks the built work against it;
  • and, if something goes wrong, whoever has to decide whose fault it was.

That last reader is why vagueness is expensive. A note that could mean two things will eventually be read the cheaper way.

The verbs that carry obligation

You will meet all of these in your own notes next lesson. Listen and repeat.

Diagnostic Practice · 12 min

What do you already control?

Measurement, not teaching. Answer from what you know now.

Lexical Matching

Match each spec phrase to what it actually signals. Click the phrase, then its meaning.

A binding obligation — the thing must happen, and failure is a violation
Permission — the contractor is allowed to, but is not required to
A recommendation — good practice, but not enforceable as written
Points at an external standard that governs how it is done
Limits the requirement to the conditions in which it actually applies
Makes the work conditional on someone else’s approval
Teacher note If she confuses shall and should, that is the single highest-value thing to fix in this unit — and it is a real Portuguese interference, since deveria and deverá are one letter apart and map to opposite ends of this scale.
MCQ Reading

Choose the version that would survive a plan check.

1. You need the contractor to confirm site conditions before building. Which note does that?

2. Which of these grants a choice rather than imposing a requirement?

3. Why does spec English usually avoid naming the contractor as the subject?

4. Which citation is enforceable?

Baseline Performance · 15 min

Write three requirements

Your Day One marker for this unit. You will rewrite these in Lesson 8.

Task card

Your teacher describes three things, in plain speech. You write them as drawing notes.

Turn each spoken intention into a note you would be willing to put on a stamped set.

  • “The electrician has to run the new circuit from the existing main panel, not a new one.”
  • “Whatever equipment they use has to be proper listed equipment, and the city has to be able to inspect it.”
  • “They need to leave enough space in front of the subpanel to open it and work on it.”

Write them by hand or type them. Keep them — they are compared directly against your Lesson 8 versions.

Teacher note Do not correct these. Note specifically: does she use shall at all? Does she name a person as subject? Does she cite anything? All three of her attempts map onto real notes in her own set, which she meets next lesson — the recognition is the hook.

Feedback & Reflection · 5 min

What was hardest?

  1. Which of the three was hardest to word, and why?
  2. Did you write any of them starting with The contractor…? What made that feel natural?
  3. In Portuguese, would you have used deverá in all three? Would that have been right in all three?

Wrap-up · 5 min

Before the next lesson

Homework. Open the electrical notes on your Wooster Avenue set — the sheet with the CEC citations. Do not study it. Just count how many sentences contain the word shall, and how many do not. Bring both numbers.
