Estimating Caution
Ordinary risk of a missed scope item, ambiguous specification, or unclear responsibility split.
Project 02
Review one residential bidding package and produce a document register, scope map, exclusion list, risk list, and prioritized clarification log before detailed takeoff.
These cues appear at the point of work. They identify document-control failures, scope gaps, and unresolved conflicts before they become uncosted work or an untraceable bid.
Ordinary risk of a missed scope item, ambiguous specification, or unclear responsibility split.
An error here can leave a required scope item unpriced or a document conflict unresolved in every later chapter.
Practical recordkeeping: document register entries, revision references, and response tracking.
Bid-submission requirements, question-routing rules, or clarification procedures vary by company. Verify before proceeding.
Follow the specific markup, measurement, or PDF-comparison tool's instructions for the application in use.
Sheet, section, revision, and date guidance for every scope determination and clarification.
This project qualifies you to review a residential bidding package before any quantity is measured. The finished work product is one controlled pre-estimate package containing a completed active document register, a verified scale and sheet inventory, a scope map identifying included and excluded work, a list of owner, contractor, subcontractor, supplier, utility, and designer responsibilities, a list of allowances, alternates, unit prices, and provisional work, a prioritized clarification log with responses, and a final pre-takeoff review summary with authorization to proceed.
You will confirm the bidding package is complete and current, review every document category from site through specifications, identify what is shown but not narrated, what is narrated but not shown, and what is required for a complete installation but not assigned to any party, convert every unresolved item into a classified and prioritized clarification, submit and record responses, and update the scope map and document register before takeoff begins.
This is the second project in the book, and it opens the workbook you built in Chapter 1. Every quantity you measure from Chapter 3 through Chapter 16 depends on the scope boundaries, exclusions, and clarification responses recorded in this project. A takeoff built on an unreviewed document set produces a number that cannot be defended later.
Every quantity takeoff chapter that follows — sitework in Chapter 3, concrete in Chapter 4, framing in Chapter 5, and every chapter through exterior work in Chapter 16 — begins by opening the scope map and clarification log built in this project. A takeoff performed against an unreviewed plan set risks measuring superseded geometry, missing an item shown on one sheet but omitted from another, or pricing work that is actually an owner responsibility.
The document-verification and clarification discipline built here — confirming sheet currency, cross-referencing drawings against specifications, and converting every open question into a classified, prioritized, and tracked item — is the same discipline the Chapter 19 proposal depends on when it states exclusions, assumptions, and unresolved clarifications to the client.
This project covers:
This project does not authorize the learner to:
Any scope item that remains unresolved after the question deadline must be converted into an approved assumption, allowance, alternate, unit price, exclusion, or contingency before takeoff begins.
Establish these conventions before any document is marked up or any clarification is written, and do not change them mid-review without a logged reason.
| Term | Definition |
|---|---|
| Active document set | The current, non-superseded plans, specifications, addenda, and clarifications governing the estimate |
| Superseded document | A document replaced by a later revision; removed from the active set but retained in the archive |
| Scope map | The record identifying which work is included, excluded, or assigned to another party, by area and system |
| Shown but not narrated | Work appearing on a drawing with no corresponding description in the scope narrative or specifications |
| Narrated but not shown | Work described in the scope narrative or specifications with no corresponding drawing detail |
| Required but not assigned | Work necessary for a complete installation that no document assigns to any party |
| Clarification | A written question tied to a specific document reference, describing the issue and its estimating impact |
| Conversion | Turning an unresolved clarification into an approved assumption, allowance, alternate, unit price, exclusion, or contingency |
Before reviewing any sheet or specification section, record the following on the document register:
Project: ______ Bid due date: ____________ Site-visit date: ____________ Question deadline: ____________
Delivery method: ______ Required forms: ______ Bonds required: ______ Signatures required: ______
Every chapter takeoff from Chapter 3's sitework quantities through the Chapter 20 capstone depends on the scope map, exclusion list, and clarification log built in this project. A document set reviewed here as complete and consistent becomes the foundation every later measurement traces back to.
Never review a drawing in isolation from its corresponding specification section, and never review a specification section without locating the drawings it governs. A door schedule without the specified hardware group, or a hardware specification without the door schedule it applies to, produces an incomplete scope determination even when each document is individually clear.
Verify printed or digital scale against a known written dimension before taking any scaled measurement from a drawing. Do not scale a drawing when a written dimension, schedule, or approved clarification already controls that value.
Confirm every sheet and specification section listed in an index is present, and remove superseded documents from the active set before mapping scope. Reviewing scope against a superseded sheet produces a scope map that must be entirely redone once the correct revision is identified.
Write each clarification with its specific document reference, the exact issue, the estimating impact, and a specific question. A clarification without a document reference cannot be verified as resolved when a response is received.
Confirm how the markup or PDF-comparison tool identifies revision clouds, layer changes, and superseded content before relying on it to detect differences between document versions. Some tools do not flag every type of revision automatically.

Document Review / Scope Mapping / Clarification Control
Quantity: one controlled pre-estimate package containing a completed active document register, a verified scale and sheet inventory, a scope map, an exclusion list, a responsibility list, a prioritized clarification log with recorded responses, and one approved pre-takeoff review summary, produced from one complete residential bidding package.
| Deliverable | Quantity | Basis | Contents | Preparation / Purpose |
|---|---|---|---|---|
| Active document register | 1 | Section E, Steps 1–5 | Sheet or section, title, date, revision, status | Confirms every document is present, current, and non-conflicting |
| Scale and sheet-verification record | 1 | Section E, Step 6 | Written dimension used, scaled result, discrepancy if any | Confirms scale reliability before any scaled measurement is used later |
| Scope map | 1 | Section F, Steps 8–15 | Site, architectural, structural, MEP, and specification scope by area and system | Identifies shown-but-not-narrated, narrated-but-not-shown, and required-but-not-assigned work |
| Responsibility list | 1 | Section G, Steps 16–18 | Owner, contractor, subcontractor, supplier, utility, municipal, designer | Assigns responsibility for demolition, protection, temporary work, permits, testing, inspections, cleanup, closeout |
| Exclusion and allowance list | 1 | Section G, Steps 19–20 | Allowances, alternates, unit prices, deferred selections, provisional work, explicit and proposed exclusions | Separates fixed scope from allowance, alternate, and excluded work |
| Clarification log | 1 | Section H, Steps 21–29 | Document reference, issue, estimating impact, question, classification, priority, response | Tracks every open question from identification through resolution |
| Pre-takeoff review summary | 1 | Section I, Step 30 | Confirmation that all deliverables are complete and authorization to proceed is obtained | Final gate before Chapter 3 takeoff begins |
| Field | Type | Basis |
|---|---|---|
| Document reference | Input | Exact sheet, section, schedule, or detail supporting the clarification |
| Issue | Input | Specific inconsistency, ambiguity, or omission identified |
| Estimating impact | Input | What cannot be quantified or priced until the item is resolved |
| Question | Input | Specific, answerable question directed at the correct recipient |
| Classification | Input | RFI, owner, supplier, subcontractor, code, inspector, or internal assumption |
| Priority | Input | Based on cost, scope, safety, schedule, and risk |
| Response and conversion | Input | Recorded answer, or the approved assumption, allowance, alternate, unit price, exclusion, or contingency used when no answer is received |
Inspect the finished pre-estimate package using the same checks regardless of which document category or clarification was reviewed.
Complete the Pre-Takeoff Review Worksheet in the Inspection Checklist section below before beginning Project 03.
Probable cause: the sheet was printed or exported at a scale other than the stated scale, or the digital file was resized during transmission.
Confirmation: measure a second known written dimension at the stated scale and compare the result to the first discrepancy.
Correction: obtain a correctly scaled copy of the sheet from the document source and repeat the scale-verification step before using any scaled measurement from that sheet.
Reinspection: repeat the scale-verification check on the corrected sheet and record the result on the scale and sheet-verification record.
Probable cause: a later revision was received but the earlier revision was not removed from the active set.
Confirmation: compare revision dates and addendum references across all versions of the sheet.
Correction: move the superseded sheet to the archive, update the document register with the current revision, and re-check every scope-map entry that referenced the superseded sheet.
Reinspection: repeat the completeness and currency checks on the corrected register.
Probable cause: the referenced drawing was omitted from the package, or the specification references a sheet number from a different revision of the plan index.
Confirmation: check the plan index for the referenced sheet number and confirm whether it exists in the current or an earlier revision.
Correction: add a clarification log entry classified as an RFI, requesting the missing drawing or a confirmed cross-reference.
Reinspection: confirm the clarification log entry includes the exact specification section and sheet reference before submission.
Probable cause: the issue was identified verbally or from memory rather than recorded directly from the document during review.
Confirmation: review the clarification log entry for a blank or vague document-reference field.
Correction: return to the source document, record the exact sheet, section, schedule, or detail, and update the clarification log entry before resubmission.
Reinspection: repeat the clarification check on the corrected entry.
Probable cause: the item was reviewed for its physical scope but not cross-checked against the responsibility list during Section G.
Confirmation: compare the scope map entry against the responsibility list for a matching assignment.
Correction: add the item to the responsibility list with its assigned party, or add a clarification log entry if no document assigns responsibility.
Reinspection: repeat the responsibility check after the correction is recorded.
Probable cause: the recipient did not respond in time, or the question was misrouted to the wrong classification.
Confirmation: check the submission date and classification recorded in the clarification log against the question deadline.
Correction: convert the item into an approved assumption, allowance, alternate, unit price, exclusion, or contingency, and record the conversion decision and its basis in the clarification log.
Reinspection: confirm every unresolved clarification has a recorded conversion before the pre-takeoff review summary is prepared.
Probable cause: Section H, Step 9 was skipped, or a clarification's conversion was not completed before Section I began.
Confirmation: review the clarification log for any entry without a recorded response or conversion.
Correction: complete the conversion for every remaining open item, then re-update the scope map and document register.
Reinspection: repeat the Common Review Inspection section before re-preparing the pre-takeoff review summary.
This project ends with an approved pre-takeoff review summary, not an open review file.

Pre-estimate package declared complete: ______ (Pass/Fail) Date: ____________ Estimator name: ____________
With the review complete and every clarification resolved or converted, review the finished package against the Pre-Takeoff Review Worksheet and confirm the document register is complete and current, scale has been verified for every drawing type used, the scope map correctly identifies shown-but-not-narrated, narrated-but-not-shown, and required-but-not-assigned work, the responsibility list assigns every party correctly, the exclusion and allowance list separates allowances, alternates, unit prices, deferred selections, provisional work, and exclusions, every clarification log entry has a recorded response or documented conversion, and the pre-takeoff review summary has been approved. If a check fails, identify whether the error occurred in document control, scope mapping, responsibility assignment, or clarification tracking before correcting it and re-running the affected check.
You have completed the second project in the construction estimating sequence: reviewing plans, scope, and specifications before any quantity is measured. This project required you to review plan sheets for completeness, currency, and internal consistency (ET-007), identify scope boundaries among owner, contractor, subcontractor, supplier, utility, municipal, and designer responsibilities (ET-008), identify excluded work, allowances, alternates, unit prices, and provisional work (ET-009), locate and cross-reference specifications with drawings, schedules, and details (ET-010), flag missing, conflicting, or ambiguous information before takeoff begins (ET-011), and create a classified, prioritized estimating clarification list with recorded resolutions (ET-012).
You now have a controlled pre-estimate package — a document register, scope map, exclusion list, responsibility list, and clarification log — that every remaining takeoff chapter in this book depends on. That system carries directly into the next project: measuring sitework and excavation quantities against the scope boundaries and clarification responses recorded here.
Store your document register, scope map, exclusion list, responsibility list, clarification log, and pre-takeoff review summary in the estimating record alongside the Chapter 1 workbook. You will reference these records throughout every remaining chapter in this book.
