Chapter 7
Measuring Carpentry and Miscellaneous Items

2. Objectives Upon completion of this chapter, you will be able to:
Describe a system that will allow an estimator to accurately measure detailed carpentry work on a large project
Calculate quantities of lumber and sheet materials

3. Objectives (cont’d.)
Describe how to measure carpentry work in a takeoff
Describe how carpentry work is classified in a takeoff
Measure rough carpentry, finish carpentry, and miscellaneous items from drawings and specifications
Complete a manual takeoff of carpentry work and miscellaneous items

4. Measuring Rough Carpentry
Detailed carpentry work quantity takeoff
Requires comprehensive carpentry knowledge when estimating
Standard practices and code requirements
Framing methods and design requirements
Estimating commercial and institutional buildings
Different skills required

5. Board Measure Unit of measurement of lumber
Figure 7.1 Sample Board Measure Calculations (Delmar/Cengage Learning)

6. Metric Units Metric system: Lumber will be in millimeters
Sheathing does not change
Described in mm rather than inches
Takeoff process
Items of lumber: measured in linear meters

7. Measuring Notes—Rough Carpentry
Generally:
Lumber
Measured in board measure or linear meters
Measure lumber separately
Dimensions, dressing, grade, and species
Describe special treatment required
Kiln dried, pressure treated, etc.

8. Measuring Notes—Rough Carpentry (cont’d.)
Wall boards
Measured in square feet or square meters
Do not deduct for openings
Less than 40 square feet
Classify wall boards
Measure separately
Framing work
Lumber is classified and measured separately

9. Measuring Notes—Rough Carpentry (cont’d.)
Other considerations:
Trusses, truss joists, and truss rafters
Manufactured beams, joists, and rafters
Sheathing
Copings, cant strips, fascias
Soffits
Sidings

10. Measuring Notes—Rough Carpentry (cont’d.)
Vapor barriers and air barriers
Underlay and subfloors
Blocking and furring
Rough hardware

11. Measuring Finish Carpentry and Millwork
Finish carpentry on commercial project
Materials
Supplied by a millwork subcontractor
Installed by general contractor
Architectural woodwork
Supplied by millwork contractor as finish carpentry
Supplied and installed by custom subcontractor

12. Measuring Finish Carpentry and Millwork (cont’d.)
Estimators should be familiar with:
Trade scope definitions of finish carpentry
Architectural woodwork in project location
Evaluate supplied items
Items outside scope of subtrades
All are priced for installation costs and supply

13. Measuring Notes—Finish Carpentry
Generally:
Classify and measure items separately
Rough carpentry: grounds, rough bucks, etc.
Include allowance for rough hardware
Metalwork: measured under miscellaneous metals
Glazing: include in glazing section
Unless integral part of prefabricated cabinet work

14. Measuring Notes—Finish Carpentry (cont’d.)
Other considerations:
Trim
Shelving
Stairs
Cabinets, counters, and cupboards
Paneling

15. Doors and Frames Usually obtained from subcontractors
Quote prices and deliver goods
General contractors
Estimate cost of handling and installing
Different sections of specifications
Deal with metal and wood doors, frames, assemblies, and special doors

16. Windows General contractors Small jobs Obtains prices from subtrades
No work for them to measure
Small jobs
May not be worthwhile hiring separate specialists
Components may be obtained directly from suppliers

17. Miscellaneous Metals Miscellaneous metals trade
Prices received from specialized subcontractors
Supply and installation
“Supply only”
General contractor
Ability to prepare a realistic estimate
Wide scope

18. Specialties Specialty trades Wide-ranging trade section
Subcontractors will offer different price quotes
Example: bathroom accessories

19. Finish Hardware Supply cost Estimating costs
Cash allowance is often specified on larger projects
Otherwise obtained from a subcontractor
Estimating costs
Calls for quantity takeoff of all finish hardware requirements

20. Measuring Exterior and Interior Finishes
General contractor’s estimator
Does not usually measure finishing work for an estimate
Almost invariably subcontracted these days
Performed on some occasions

21. Examples Carpentry and miscellaneous work takeoff—house example
Takeoff notes shown as Figure 7.2a
Rough Carpentry—Floor System
Rough Carpentry—Wall System
Rough Carpentry—Roof System
Finish Carpentry

22. Examples (cont’d.)
Exterior and interior finishes takeoff—house example
Takeoff shown as Figures 7.3 and 7.4
Exterior finishes
Interior finishes

23. Summary Thorough knowledge of carpentry construction
Required to prepare a detailed estimate
Estimator must apply a systematic approach
Carpentry requirements of commercial and institutional projects
Usually well detailed
