Transcript of 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
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

Finish Carpentry Recap and Pricing Notes Example 1—House– Refer to Figures 12.6 through 12.10
• Masonry Work Pricing Notes Example 2—Office/Warehouse Building– Refer to Figure 12.11
