Four Sheet Indexes

B1 The Drawing Set
About this lesson ▾

Four different jobs, four different jurisdictions, four different sheet counts — and the same five sheets always open the set the same way.

Your own index

Read out your own sheet index, first sheet to last, in order.

Predict

Before you compare your index with three others, predict:

1. A set with 9 sheets and a set with 4 sheets — how similar do you think their opening sheets will be?

Input & Noticing · 14 min

The first five sheets, verbatim

From one of your own sets.

L4NEW GRADING, DRAINAGE PLAN

Sheet counts across your four sets

ProjectJurisdictionSheets
Wooster Ave.City of Belmont7 sheets
Colonial Ln.San Jose7 sheets
Vancouver Ave.Burlingame4 sheets
Silverwood Dr.Lafayette9 sheets

Notice what stays constant across a set that is 4 sheets and one that is 9. Both start with L0, project information. Both put the existing conditions before the new design. The set that is more than twice as long does not reorganise the convention — it just adds more sheets after the same opening sequence.

That means once you can navigate a 4-sheet set, you already know the first four moves of navigating a 9-sheet one.

Discovery Check

Check the sheet-count table above.

1. Which project has the fewest sheets?

2. What do a 4-sheet set and a 9-sheet set have in common at the start?

Focus on Form · 10 min

What is always there

The fixed opening sequence

SheetWhat it always is
L0Project information — the cover sheet
L1Existing conditions — what is there now
L2New / proposed design
Later sheetsDetails, schedules, sections — vary by project

This is a question you can now answer about a set you have never seen: "Where would the existing-conditions plan be?" L1, almost always — because that is the convention, not a guess about this specific job.

The Fixed Opening

Put these four sheet types back in the order they always appear.

MCQ Reading

All the evidence is in the tables in Phase 02.

1. Which sheet is the existing site plan?

2. What do L0 and L1 do the same way on every one of your sets, no matter the sheet count?

3. Which of your four sets has the most sheets?

4. Why does knowing a 4-sheet set help you navigate a 9-sheet one?

Communicative Task · 10 min

Predict the sheet

Task card

A set you have never seen, with an unknown number of sheets

Your teacher names something they need — "the existing conditions," "the project info," "a construction detail." Say which sheet it would most likely be on, and why.

  • Answer from the convention, not from memory of one specific set.
  • Say "almost always" or "probably" where the convention allows variation.
  • For the last one, say honestly that it could be anywhere — details vary by project.
Before You Predict

One check before your teacher starts naming things.

1. If you are not completely sure which sheet something is on, what should you say?

Feedback · 4 min

Convention or memory?

Were you answering from the pattern, or trying to remember one specific set? The pattern is the more useful skill — it works on a set you open for the first time.

Which Is More Useful?

Apply today's lesson.

1. Which skill works on a set you are opening for the very first time?

Wrap-up · 4 min

Before the next lesson

Homework. Find the scale notation on one of your own sheets — the fraction, not just the word "scale." Practise saying it aloud.

Quick Check

One check before you go.

1. What exactly should you find for homework?
