1. Construction Estimating Using Excel Professor Locurcio CON4003, CVE4073, CVE5073

2. Performing Quantity Take Offs Work Packages Communication in the Field Counted Items Linear Components Sheet and Roll Items Volumetric Goods Quantity-From-Quantity Goods Waste

3. The process of preparing a complete list of all components needed to complete the project Includes all components including site and direct overhead Units include all common units (feet, sq. feet, yards, etc.), months, each, and lump sum

4. Determine all materials, equipment, and labor Building the project from the bottom up in the mind Example: Prehung Door

6. Related labor tasks are divided into work packages Job cost codes may be broken into multiple work packages Example: The same lumber used in different floors of a building Should match project sequence and scheduling

7. Foundation wall package (top) Foundation footing package (bottom) Anchor bolts are placed in concrete first, so they are part of the wall package

8. Estimators and workers need to communicate to prevent delays in the project Methods and procedures can differ, creating problems

9. Counted Items Linear Components Sheet and Roll Items Volumetric Goods Quantity-From-Quantity Goods

10. Simplest way to determine quantity Important to check off items already counted Count repetitive items using equations (????)

11. Members at both ends, Eqn. 4-1 Number = (Distance / Spacing)+1 Member at one end, Eqn. 4-2 Number = (Distance / Spacing) No end members, Eqn. 4-3 Number = (Distance / Spacing)-1

13. 120 ft. 16 + 1

15. Components measured by length Can be connected with lap or butt joints

16. Distance between the start of two linear components Number = (Length / Effective Length)

18. Components measured by area Can be butt, lap, or spaced jointed Two methods: Area and Row/Column

20. 8ft 50ft Effective Area 8 x 18 = 128 in3 15 5/8” 3/8” 16” 8”

21. Number = (Number Rows )(Number Columns ) Eqn. 4-18 Example:

22. Volume = (Length)(Width)(Height) Eqn. 4-19 Additional volume formulas in Appendix A Example (Concrete, Sand, Rock)

23. Quantity estimated from another quantity Examples: 1 gal paint covers 250sf of wall 1 lb of nails covers 100sf of roofing

25. Unavoidable waste should be included Expressed as a percentage of calculated quantity

29. Distance = 120 ft = 120 ft (12 in/1 ft) = 1,440 inches Spacing = 16 inches on center Number = (1,440 inches / 16 inches) + 1 = 91 studs

30.  Book problems only ask for quantity  I require…. a) Quantity… plus b) Material Cost c) Equipment Cost d) Labor Cost e) Total Cost per unit f) Excel Format

32. 1. Identify items to be counted 2. Determine quantities needed for each item 3. Select “correct” RSMeans item – CSI format 4. Cite RSMeans line item selected 5. Use Excel columns for Material & Labor Costs 6. Note… cite units for all items  Differs from item to item  Differs from text questions 7. Determine total cost for each item 8. Sum all line item costs for materials & labor 9. Add OH & Profit at end

33. 1.Homework due for Thursday…. 2.Shed Estimate… 3 documents a)Cover sheet b)Transmittal letter w/total cost c)Excel sheet with itemized costs
