Job Overview

This project qualifies you to produce a coordinated finish-carpentry estimate for one residential project. The finished work product is one estimate covering interior doors, frames, jambs, casing, baseboard, crown and wall trim, closet shelving, stock-length optimization, fasteners and finishing materials, and labor, entered into the cost-code sections of the workbook built in Project 01.

You will reconcile the door schedule against the plans, separate door types and hardware groups, measure casing and baseboard by room, measure crown and wall trim by room and elevation, convert linear quantities into stock lengths with waste, calculate fasteners and finishing materials, coordinate scope boundaries with flooring, cabinets, painting, hardware, and electrical, price every component from dated quotations, reconcile door count and trim quantities against the schedules, and prepare the estimate by room, opening, profile, material, labor, and total.

This project follows Project 10, where wall and ceiling substrates were estimated, and precedes Project 12, where cabinets, countertops, and built-ins are estimated. Interior trim and finish carpentry cannot be measured accurately until wall, opening, and ceiling conditions are established, and cabinet coordination in the next project depends on the opening and trim boundaries set here.

Skills You Will Demonstrate

  • ET-061 — Count interior doors by tag, type, and hardware group, reconciled against the door schedule.
  • ET-062 — Calculate casing quantities by opening perimeter, profile, and stock length.
  • ET-063 — Calculate baseboard quantities by room perimeter with the approved opening-deduction rule.
  • ET-064 — Estimate crown or wall trim by room and elevation, including built-up profiles.
  • ET-065 — Estimate fasteners, adhesive, and caulk for finish-carpentry installation.
  • ET-066 — Prepare a complete finish-carpentry estimate with reconciled quantities, labor, pricing, and documented scope boundaries.

Where This Skill Fits

The drywall estimate from Project 10 establishes finished wall and ceiling surfaces; this project measures every trim element applied to those surfaces along with every door opening cut into them. The door count and hardware groups established here are the same count Project 12 uses to coordinate cabinet, appliance, and built-in openings, and the same count Project 15 uses to verify electrical switch and device locations near door swings.

The stock-length optimization and material-specific waste discipline used here is the same discipline applied to flooring transitions in Project 13 and to paint sundries in Project 14. Errors in door count or trim perimeter carry directly into the labor estimate in Project 17 and the selling price in Project 18.

Scope and Intended Use

This project covers:

  • counting interior doors by tag, type, swing, core, rating, frame, and hardware group, reconciled against the door schedule
  • measuring casing by opening perimeter, side, head, reveal, profile, and stock length
  • measuring baseboard, shoe, and quarter round by room perimeter with the approved opening-deduction rule
  • measuring crown, picture rail, chair rail, panel molding, wainscot cap, and wall trim by room and elevation
  • measuring closet shelving, rods, cleats, brackets, and supports where assigned
  • converting linear quantities into stock lengths with cut optimization and pattern matching
  • calculating fasteners, adhesive, biscuits, dowels, plugs, shims, filler, and caulk
  • coordinating flooring, cabinet, painting, hardware, and electrical scope boundaries
  • pricing doors, frames, trim, millwork, hardware, fasteners, finishing, and delivery from dated quotations
  • preparing the estimate by room, opening, profile, material, labor, finish, and total

This project does not authorize the learner to:

  • select door hardware, profiles, or finish grade on the owner's behalf; use only the schedule, specification, or approved selection provided
  • price field cutting of specialty stair components, custom millwork, or shop-fabricated items without a fabricator quotation covering that work
  • assume any stock length, profile, or species not confirmed by the specification, schedule, or a dated supplier quotation
  • issue this estimate as a client-facing proposal; that document is prepared separately in Project 19

Any door count, opening perimeter, or room perimeter that does not reconcile against the schedules must be resolved before pricing begins.

Workbook Conventions for This Project

Apply these definitions consistently across every room and opening measured in this project. Do not change them mid-estimate without a logged revision in the Project 01 workbook.

Room perimeterThe total wall length of a room measured at floor level, used for baseboard, before the approved opening-deduction rule is applied
RevealThe recessed margin between the jamb edge and the inside edge of casing, defined for each opening type
Built-up profileA trim assembly made from two or more individual components installed together, such as a crown with cove and bed molding
Stock-length optimizationAssigning net linear quantities to available stock lengths to minimize waste while preserving pattern match
Hardware groupThe set of hinges, locksets, closers, and stops assigned to a door tag or type

Project-Information Confirmation

Estimate number: ______     Revision status: ______     Pricing date: ____________     Door schedule revision: ____________

Prerequisites

Common Field Fundamentals

Every finish-carpentry estimate in this book is built the same way: reconcile the count, measure the perimeter, convert to stock length, apply material-specific waste, calculate fasteners and finishing, coordinate trade boundaries, and price from dated quotations. Applying this sequence consistently is what keeps the door count, casing quantity, and labor estimate traceable from this chapter through the Project 20 capstone.

Reconciling the Door Schedule

Compare every door shown on the floor plans against the door schedule before any hardware or casing quantity is calculated. Record the tag, size, swing, core, rating, frame, and hardware group for each door exactly as listed on the schedule. Where a plan shows a door not listed on the schedule, or the schedule lists a door not shown on the plan, treat the discrepancy as an unresolved clarification and do not resolve it by independent judgment.

C. Material and Species Categories

  • Species and material separation: separate species, MDF, composite, PVC, finger-jointed, clear, stain-grade, and paint-grade materials into distinct lines; do not combine differing materials under one line item.
  • Stain-grade handling: apply pattern-matching and grain-continuity requirements only where the finish schedule specifies a stain-grade finish.
  • Specialty trim: identify built-up profiles requiring multiple components and record the assembly labor for each component separately from the material quantity.
  • Non-substitution rule: do not substitute a species, profile, or stock length not confirmed by the specification, schedule, or an approved clarification.

E. Document Review and Door Reconciliation

  1. Review plans, door schedule, finish schedule, elevations, sections, details, millwork drawings, and specifications. Record the revision date of each document used.
  2. Identify door type, size, swing, core, rating, frame, jamb, stop, casing, hardware group, finish, and responsibility for each door tag. Record these fields exactly as listed on the schedule.
  3. Count doors by tag and reconcile the schedule with the plans. Record any discrepancy as an unresolved clarification before continuing.
  4. Separate prehung, slab, pocket, bypass, bifold, barn, access, rated, and specialty doors. Assign each its own line so pricing and labor differences are not averaged together.
  5. Identify pairs, transoms, sidelights, louvers, glass, and special hardware. Record each as its own line item linked to the parent door tag.
  6. Confirm whether the quoted price includes frames, jambs, stops, hinges, locksets, closers, thresholds, seals, and painting. Record the confirmed scope on the quotation log for each door line.

F. Casing, Baseboard, and Wall-Trim Takeoff

  1. Measure casing by opening perimeter, side count, head count, reveal, profile, and stock length. Record the opening tag supporting each casing quantity.
  2. Include window casing, stools, aprons, jamb extensions, returns, rosettes, and specialty details. Record each as a distinct line linked to its opening.
  3. Measure baseboard by room perimeter and apply the approved opening-deduction rule. State the deduction rule used on the room schedule.
  4. Add corners, returns, transitions, and stock-length waste. Record the corner and return count separately from the linear footage.
  5. Measure shoe, quarter round, and cap, and flexible trim separately. Do not combine these with the baseboard line.
  6. Measure crown, picture rail, chair rail, panel molding, wainscot cap, and wall trim by room and elevation. Record the elevation reference for each measurement.
  7. Identify built-up profiles requiring multiple components and assembly labor. Record each component of a built-up profile as its own material line, linked under one assembly reference.

G. Shelving, Stair Finish, and Material Categorization

  1. Measure closet shelving, rods, cleats, brackets, and supports where assigned. Record the room and closet type for each shelving line.
  2. Count stair finish items only from approved details. Do not estimate stair stringers, treads, risers, rails, or balusters without a specific approved detail reference; treat missing stair details as an unresolved clarification.
  3. Separate species, MDF, composite, PVC, finger-jointed, clear, stain-grade, and paint-grade materials. Apply the material category rules in Section C.

H. Stock Optimization, Waste, and Consumables

  1. Convert linear quantities into stock lengths with cut optimization and pattern matching. Use the approved stock-length reference and record the assigned stock length for each line.
  2. Apply waste by profile, stock length, stain grade, room geometry, and cut complexity. Record the waste percentage and its basis on each line; do not apply one waste percentage to every profile.
  3. Calculate finish nails, screws, adhesive, biscuits, dowels, plugs, shims, filler, caulk, and touch-up. Base the quantity on linear footage, joint count, and manufacturer coverage.
  4. Calculate primer, paint, stain, clear coat, and shop finishing only when included in this estimate's scope. Record whether finishing is included here or excluded and coordinated with Project 14.

I. Coordination, Labor, and Pricing

  1. Include field measurement, templates, mockups, samples, and shop drawings where required. Record which items require field verification before ordering.
  2. Include delivery, protected storage, acclimation, sorting, culling, handling, and disposal. Record these as separate cost lines, not absorbed into material unit cost.
  3. Estimate labor by door, hardware preparation, casing, base, crown, wall trim, shelving, stair, sanding, and punch. Assign a separate labor line for each task category.
  4. Adjust production for occupancy, high ceilings, stain grade, irregular walls, specialty joints, and protection. Record the adjustment reason on each affected labor line.
  5. Coordinate flooring, cabinets, painting, hardware, and electrical boundaries. Record each boundary in the trade-boundary log with the responsible trade for supply and installation.
  6. Price doors, frames, trim, millwork, hardware, fasteners, finishing, and delivery from dated quotations. Record the quotation date, source, and expiration for every priced line.
  7. Identify long-lead custom doors, profiles, species, hardware, and factory finishes. Record the lead time and its effect on the schedule assumption.

J. Reconciliation, Documentation, and Review

  1. Reconcile door count, opening perimeter, room perimeter, and trim quantities. Compare the workbook totals against the door schedule and room schedule independently.
  2. Prepare the estimate by room, opening, profile, material, labor, finish, and total. Enter the completed estimate into the Project 01 workbook's cost-code sections.
  3. Document exclusions and unresolved opening, profile, hardware, finish, and responsibility questions. Record each in the assumptions, exclusions, and clarifications register linked to the affected line.
  4. Complete independent review of doors, stock lengths, specialty trim, and finish labor. Confirm the review is performed by someone other than the original estimator where company policy requires it.

Skill Check

  1. Why must the door count be reconciled against the door schedule before hardware or casing is priced?
  2. What is the difference between opening perimeter and room perimeter, and which trim category depends on each?
  3. Why must shoe, quarter round, and cap be measured as separate lines from baseboard?
  4. What must be confirmed on a door quotation before its price is entered into the workbook?
  5. Why does waste for casing, base, and crown vary by profile, stock length, and stain grade instead of using one percentage?
  6. What must be recorded in the trade-boundary log, and what happens if a shared item is left off the log?
  7. Why must stair finish items be estimated only from approved details rather than field judgment?
  8. What is a built-up profile, and how must its components be recorded on the takeoff?
  9. Why must field measurement, templates, or shop drawings be identified before ordering certain finish-carpentry items?

Performance Check

With the finish-carpentry estimate entered into the workbook, review the finished file against the Finish-Carpentry Verification Worksheet and confirm the door count fully reconciles against the door schedule, casing and baseboard quantities reconcile against opening and room-perimeter data, crown and wall-trim built-up profiles show every component, stock-length optimization and waste are applied per profile rather than as one blanket percentage, fasteners and finishing quantities are calculated from linear footage and coverage, the trade-boundary log is complete, every unit cost carries a date and confirmed scope, and the independent review is complete. Complete the Finish-Carpentry Verification Worksheet and correct any failed item before entering the estimate into the workbook's summary sheets and beginning Project 12. If a check fails, identify whether the error occurred in reconciliation, measurement, waste basis, coordination, or pricing before correcting it and re-running the affected check.

Project Closeout

You have completed the eleventh project in the construction estimating sequence: preparing a coordinated finish-carpentry estimate. This project required you to count interior doors by tag, type, and hardware group reconciled against the door schedule (ET-061), calculate casing quantities by opening perimeter, profile, and stock length (ET-062), calculate baseboard quantities by room perimeter with the approved opening-deduction rule (ET-063), estimate crown and wall trim by room and elevation including built-up profiles (ET-064), estimate fasteners, adhesive, and caulk from linear footage and coverage (ET-065), and prepare a complete, reconciled, and independently reviewed finish-carpentry estimate (ET-066).

The reconciled door count, room perimeters, and trade-boundary log built here carry directly into Project 12, where cabinet, countertop, and built-in openings are coordinated against the same door and wall data, and into Project 17, where the labor tasks identified here are converted into crew hours and duration.

Store your reconciled door count, finish-carpentry estimate, trade-boundary log, and independent review record in the estimating record. Project 12 begins with the door and wall data confirmed here.
