3.  Rough Carpentry  Framing, walls and roof  Finish Carpentry  Wood trim, shelving and handrails  Cabinetry  Cabinets and countertops

5.  Joists covered with OSB or Plywood Sheathing  Bearing on sills, walls or girders supported by posts

6.  P&G are used to support floor system  Posts are bid as counted items  Girders are bid as Linear Components

8. 3 ea 2x12 Nailed together 31 13 14

9. 3 ea 2x12 Nailed together

11.  Floor joists may be engineering I-Joists  Bid as counted item  If need joist blocking its counted as linear component

12. OSB = oriented strand board Engineered wood I-joist

13.  Treated as Sheet goods  Length of decking is assumed to run entire length of deck – when purchasing random lengths

14.  Consist of top and bottom plates, headers, hold downs (straps/ties), blocking, sheathing and obviously studs  Bidding  Top and Bottom Plates – Linear Components  Studs – linearly OR by quantity (depending on method)  May be in LF or Board Feet  Count the total of 2 x 4 lumber

15. A board foot, simply, is equal to 144 cubic inches of wood. Think of it as a piece I inch thick and 12 inches square. Since board footage is always calculated in quarters of an inch thickness, starting at no less than 1 inch (even if you order less than an inch, you’ll pay for the i-inch thickness). In inches BF = Volume/144 = BF So a 2”x4”x8’ board = 2x4x96 = 768/144 = 5.3 BF
