Chapter 12 Pricing Masonry Carpentry, and Finishes Work

Objectives Upon completion of this chapter, you will be able to: –Describe the specific job factors that affect the price of masonry work –Explain what influences the material price of masonry bricks and blocks –Describe the specific job factors that affect the price of rough carpentry work

Objectives (cont’d.) –Explain what influences the material price of lumber –Describe how finish carpentry is priced –Describe how interior and exterior finishes are priced

Objectives (cont’d.) –Complete the recap and pricing of masonry work, rough carpentry, finish carpentry, and interior and exterior finishes using manual methods –Use Excel spreadsheets to price masonry work

Introduction Masonry work, rough carpentry, and finish carpentry –Commonly subcontracted –Still performed by some contractors Specialized companies –May have questionable reliability record Price errors

Masonry Labor costs –Laying masonry –Installing accessories Ladder reinforcing and wall ties Masonry materials Modularization –Factory construction of masonry panels Not common

Masonry Productivity Factors affecting productivity: –What is being built –Workmanship required –Size and weights of units –Mortar and bond used –Design complexity –Presence or lack of repetition –Availability of skilled trade workers

Figure 12.1 Masonry Work Productivities (Delmar/Cengage Learning)

Masonry Materials Prices vary –Depend on requirements –Normally found in specifications When not provided, based on materials agreed upon (e.g., materials defined in the bid) Wastage –More materials delivered than used Accounted for in takeoff quantities

Rough Carpentry Fabricated off-site –Assembled at the job site Costs –Labor and material Lumber or fabricated components Cranes Beams Trusses

Rough Carpentry Productivity Factors affecting productivity: –Carpentry components –Size of cross-section and length lumber –Power tool use –Design complexity –Presence or lack of repetition –Off-site fabrication

Rough Carpentry Materials Specifications define: –Species –Use classification –Lumber grade Softwood lumbar classifications: –Yard, structural, factory, and shop lumber –Rough, surfaced, and worked lumber –Boards, dimension, and timber

Rough Carpentry Materials (cont’d.) Lumber lengths and waste factors –Generally multiples of two feet Waste factors still required Lumber grades –Information on ability to meet requirements Rough hardware –Mostly consists of nails Other fasteners may also be required

Finish Carpentry and Millwork Pricing finish carpentry –Applying materials and labor prices to items measured in takeoff process Productivity of labor crews –Influenced by job factors Similar to rough carpentry

Exterior and Interior Finishes Procedure: –Measure quantity of each item of in takeoff –List takeoff items on a recap –Apply separate materials and labor prices Material prices: –Determined by suppliers Productivities: –Job, labor, and management factors

Wage Rates Basic hourly wages: –Masonry foreman: $43.00 –Mason: $39.00 –Equipment operator: $40.00 –Labor foreman: $33.00 –Laborer: $30.00

Wage Rates (cont’d.) –Cement finisher: $37.00 –Carpentry foreman: $41.00 –Carpenter: $38.00 –Painter foreman: $37.00 –Painter: $34.00

Summary This chapter reviewed pricing and influential pricing factors of: –Masonry work –Rough carpentry work –Finish carpentry work –Interior and exterior finishes
