Project 02

Review Plans, Scope, and Specifications Before Estimating

Review one residential bidding package and produce a document register, scope map, exclusion list, risk list, and prioritized clarification log before detailed takeoff.

Field Cue System

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.

△

Estimating Caution

Ordinary risk of a missed scope item, ambiguous specification, or unclear responsibility split.

✋

Critical Control Cue

An error here can leave a required scope item unpriced or a document conflict unresolved in every later chapter.

⛑

Documentation Cue

Practical recordkeeping: document register entries, revision references, and response tracking.

▤

Company Policy Alert

Bid-submission requirements, question-routing rules, or clarification procedures vary by company. Verify before proceeding.

▧

Software Cue

Follow the specific markup, measurement, or PDF-comparison tool's instructions for the application in use.

▱

Traceability Cue

Sheet, section, revision, and date guidance for every scope determination and clarification.

Job Overview

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.

Skills You Will Demonstrate

  • ET-007 — Review plan sheets for completeness, currency, and internal consistency.
  • ET-008 — Identify scope boundaries among owner, contractor, subcontractor, supplier, utility, municipal, and designer responsibilities.
  • ET-009 — Identify excluded work, allowances, alternates, unit prices, and provisional work.
  • ET-010 — Locate and cross-reference specifications with drawings, schedules, and details.
  • ET-011 — Flag missing, conflicting, or ambiguous information before takeoff begins.
  • ET-012 — Create an estimating clarification list, classify each item, and record its resolution.

Where This Skill Fits

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.

Scope and Intended Use

This project covers:

  • confirming the bidding package is complete, current, and internally consistent
  • reviewing site, architectural, structural, MEP, and specification documents in sequence
  • identifying scope shown but not narrated, narrated but not shown, and required but not assigned
  • defining owner, contractor, subcontractor, supplier, utility, municipal, and designer responsibilities
  • identifying allowances, alternates, unit prices, deferred selections, and provisional work
  • writing, classifying, prioritizing, submitting, and tracking clarification questions
  • converting unresolved items into approved assumptions, allowances, alternates, unit prices, exclusions, or contingency
  • preparing the final pre-takeoff review summary and obtaining authorization to proceed

This project does not authorize the learner to:

  • begin any quantity takeoff before the pre-takeoff review summary is approved
  • resolve a design conflict, code question, or ambiguous specification independently; unresolved items must be converted into an RFI, owner question, supplier or subcontractor question, code or inspector question, or a documented internal assumption
  • proceed on a document set with unverified scale, missing sheets, or unreconciled revisions
  • submit clarification questions after the stated question deadline without company authorization

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.

Review Conventions

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.

Prerequisites

Common Field Fundamentals

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.

Document controlReceipt, due dates, active register, superseded documents, scale verification
Document reviewSite, architectural, structural, MEP, specifications, read in sequence
Scope mappingShown/not narrated, narrated/not shown, required/not assigned
ResponsibilityOwner, contractor, subcontractor, supplier, utility, municipal, designer
ExclusionsAllowances, alternates, unit prices, deferred selections, provisional work
ConflictsInconsistent dimensions, schedules, notes, sections, details
ClarificationsWritten, classified, prioritized, submitted, and tracked to response
CloseoutConversion of unresolved items, final review summary, authorization

Reading Drawings and Specifications Together

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.

C. Document Review Sequence

  • Site and logistics documents: site plan, grading plan, utility plan, access, property limits, and logistics information.
  • Architectural documents: plans, elevations, sections, schedules, details, and finishes.
  • Structural documents: foundations, framing, connections, and special inspections.
  • MEP and specialty documents: plumbing, electrical, HVAC, fire, low-voltage, and specialty documents where included in the package.
  • Specifications: products, standards, submittals, testing, warranties, installation, and closeout requirements for every system reviewed above.
  • Non-substitution rule: do not review a specification section without locating and reviewing the drawings it governs, and do not review a drawing without locating its corresponding specification section.

D. Clarification Classification and Priority Schedule

FieldTypeBasis
Document referenceInputExact sheet, section, schedule, or detail supporting the clarification
IssueInputSpecific inconsistency, ambiguity, or omission identified
Estimating impactInputWhat cannot be quantified or priced until the item is resolved
QuestionInputSpecific, answerable question directed at the correct recipient
ClassificationInputRFI, owner, supplier, subcontractor, code, inspector, or internal assumption
PriorityInputBased on cost, scope, safety, schedule, and risk
Response and conversionInputRecorded answer, or the approved assumption, allowance, alternate, unit price, exclusion, or contingency used when no answer is received

E. Preparation — Document Receipt and Verification

  1. Obtain the invitation, bid instructions, scope narrative, plan set, specifications, addenda, schedules, reports, alternates, selections, and submission forms. Confirm every listed component of the bidding package has actually been received.
  2. Record receipt date, bid due date, site-visit date, question deadline, delivery method, required forms, bonds, signatures, and acknowledgments. Enter these on the Bidding Package Control Record in the Review Conventions section above.
  3. Create the active document register. List every sheet or specification section with its title, date, revision, and status.
  4. Confirm all sheets and specification sections listed in indexes are present. Cross-check the plan index and specification table of contents against the actual document set.
  5. Identify duplicate, superseded, missing, unreadable, resized, or conflicting documents. Remove superseded documents from the active set while preserving them in the archive.
  6. Verify drawing scales against written dimensions. Select one known written dimension per drawing type, measure it at the stated scale, and record any discrepancy on the scale and sheet-verification record.
  7. Read title blocks, legends, general notes, abbreviations, revision clouds, and addendum references. Note any abbreviation or symbol that is not defined in the legend.

F. Document Review and Scope Mapping Procedure

  1. Review site, grading, utilities, access, property limits, and logistics. Mark boundaries, easements, and access constraints on the scope map.
  2. Review architectural plans, elevations, sections, schedules, details, and finishes. Cross-reference each schedule against its corresponding plan and detail.
  3. Review structural foundations, framing, connections, and special inspections. Note any special inspection requirement and its responsible party.
  4. Review plumbing, electrical, HVAC, fire, low-voltage, and specialty documents where included. Confirm which MEP systems have complete design documents versus allowance-level information.
  5. Review specifications for products, standards, submittals, testing, warranties, installation, and closeout. Cross-reference each specification section against the drawings it governs.
  6. Identify work shown on drawings but omitted from the narrative. Record each instance on the scope map as shown-but-not-narrated.
  7. Identify work specified but not clearly shown. Record each instance on the scope map as narrated-but-not-shown.
  8. Identify work required for a complete installation but not assigned. Record each instance on the scope map as required-but-not-assigned.

G. Responsibility, Exclusion, and Allowance Procedure

  1. Define owner, contractor, subcontractor, supplier, utility, municipal, and designer responsibilities. Record each on the responsibility list by scope item.
  2. Identify demolition, protection, temporary work, permits, testing, inspections, cleanup, and closeout responsibilities. Assign each to a specific party on the responsibility list.
  3. Identify owner-furnished, contractor-installed and owner-furnished, owner-installed items. Record each with its exact designation.
  4. Identify allowances, alternates, unit prices, deferred selections, and provisional work. Record each on the exclusion and allowance list with its stated basis.
  5. List explicit and proposed exclusions. Record explicit exclusions as stated in the documents and proposed exclusions identified during this review, kept in clearly separate columns.

H. Conflict Identification and Clarification Procedure

  1. Compare dimensions, schedules, notes, sections, and details for inconsistencies. Record each conflict with the specific documents compared.
  2. Flag missing dimensions, undefined assemblies, ambiguous products, incomplete schedules, and uncoordinated systems. Add each to the clarification log.
  3. Identify site conditions requiring a visit, survey, test, investigation, or owner information. Add each to the clarification log with the required action.
  4. Write each clarification with document reference, issue, estimating impact, and specific question. Use the fields defined in Section D.
  5. Classify questions as RFI, owner, supplier, subcontractor, code, inspector, or internal assumption. Assign the classification field for every clarification log entry.
  6. Assign priority based on cost, scope, safety, schedule, and risk. Rank clarifications so the highest-impact items are submitted first.
  7. Submit questions before the required deadline and record responses. Enter the submission date and the response, or its absence, for every clarification log entry.
  8. Convert unresolved items into approved assumptions, allowances, alternates, unit prices, exclusions, or contingency. Record the conversion decision and its basis for every clarification without a response by the question deadline.
  9. Update the document register and scope map after every response. Reflect each resolved clarification in both records before proceeding.

I. Closeout — Pre-Takeoff Review Summary

  1. Prepare the final pre-takeoff review summary and obtain approval to proceed. Confirm the document register, scope map, responsibility list, exclusion and allowance list, and clarification log are complete, and record the name and date of the person authorizing takeoff to begin.

Performance Check

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.

Project Closeout

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.
