17. Lump Sum Price Analysis Estimate for items paid as a “Lump Sum” Includes: ◦ Labor ◦ Materials ◦ Equipment ◦ Rental costs ◦ Profit and Overhead Typical lump sum items: ◦ Clearing and Grubbing ◦ Survey and Stakeout ◦ Temporary Traffic Signals 17

18. Lump Sum Analysis Example Item 619.13 (Temporary Traffic Signal) Labor Costs ◦ Backhoe Operator-$30.05/hr ◦ Electrician-$32.99/hr ◦ Laborer-$22.95/hr Prevailing Wages http://wpp.labor.state.ny.us/wpp/publicViewPWChanges.do?method=showIt http://wpp.labor.state.ny.us/wpp/publicViewPWChanges.do?method=showIt Installation and Removal of Temp. Poles ◦ 1 Backhoe Operator $30.05/hr * 16 hours = ◦ 2 Laborers @ $22.95/hr * 16 hours = Installation and Removal of Temp. Signal Heads ◦ 1 Electrician @ $32.99/hr * 16 hours = ◦ 2 Laborer@ $22.95/hr * 16 hours = Installation and Removal of Controller ◦ 1 Electrician @ $32.99 * 16 hours = ◦ 1 Laborer @ $22.95 * 16 hours = 18

19. Lump Sum Analysis Example-Cont. Item 619.13 (Temporary Traffic Signal) Materials ◦ Temporary Poles 4 @ $1,300.00 each ◦ Temporary Signal Heads 4 @ $250.00 each ◦ Controller, Fixed Time 1@ $1,000.00 ◦ Misc. Hardwire and Wire $1,000.00 Equipment (Installation and Removal) ◦ 1 Bucket Truck @ $18.00/hr * 24 hours ◦ 1 Backhoe @ $35.00/hr * 24 hours Profit and Overhead (20%) 19
