Conceptual Connection: Would it be worthwhile for Charlene to establish standards for atypical jobs (such as those with more than one sink cut or wider than normal)? It probably would not be worthwhile. 50.00 1.50 etting Standards, Materials and Labor Variances om Belford and Tony Sorrentino own a small business devoted to kitchen and bath granite installations. Recently, building contractors have insisted nup-front bid prices for a house rather than the cost-plus system that Tom and Tony had been using. They worry because natural flaws in the granit nake it impossible to tell in advance exactly how much granite will be used on a particular job. In addition, granite can be easily broken, meaning tha om or Tony could ruin a slab and would need to start over with a new one. Sometimes the improperly cut pieces could be used for smaller nstallations, sometimes not. All their accounting is done by a local certified public accounting firm headed by Charlene Davenport. Charlene listened to heir concerns and suggested that it might be time to implement tighter controls by setting up a standard costing system. Charlene reviewed the involces pertaining to a number of Tom and Tony's previous jobs to determine the average amount of granite and glue needed per square foot. She then updated prices on both materials to reflect current conditions. The standards she developed for one square foot of counter installed were as follows: Granite, per square foot Glue (10 oz. $0.15) Direct labor hours: Cutting labor (0.10 hr. $15) Installation labor (0.25 hr. 825) 6.25 These standards assumed that one seamless counter requires one sink cut (the space into which the sink will fit) as well as cutting the counter to fit the space available. Charlene tracked the actual costs incurred by Tom and Tony for granite installation for the next 6 months. She found that they completed 50 jobs with an average of 32 square feet gf granite installed in each one. The following information on actual amounts used and cost was gathered: Granite purchased and used (1,640 sq. ft.) Glue purchased and used (16,000 oz.) Actual hours cutting labor Actual hours installation labor The actual wage rate for cutting and installation labor remained unchanged from the standard rate.
