Reinforcement comes in the form of a mesh constructed from reinforced steel bars. These are laid at the bottom of the trench, slightly elevated by spacers to allow the concrete to flow beneath.

Slide 5 Plot plans provide necessary dimensions required for staking out a house location on an empty lot Plot plans provide necessary dimensions required for staking out a house location on an empty lot The corners of the house are located and stakes are put into the ground The corners of the house are located and stakes are put into the ground Preparing a Lot for Construction Slide 6 Stake out the house: Put a stake in the ground for each corner of the house Stake out the house: Put a stake in the ground for each corner of the house Staking requires a measuring tape and contractors level Staking requires a measuring tape and contractors level Preparing a Lot for Construction Slide 7 Batter boards are marks placed for use as references or guides during the initial excavation and rough grading of a building construction Batter boards are marks placed for use as references or guides during the initial excavation and rough grading of a building construction They consist of 2 x 4 inch wood stakes with a crosspiece of 1 x 6 inch lumber nailed to it They consist of 2 x 4 inch wood stakes with a crosspiece of 1 x 6 inch lumber nailed to it Preparing a Lot for Construction Slide 8 Building a House on the Lot The structure of a house carries the weight to its supporting element - the ground. The structure is what makes the house stand up. A house is constructed from the bottom up. The structure of a house carries the weight to its supporting element - the ground. The structure is what makes the house stand up. A house is constructed from the bottom up. These are often called load-bearing elements or systems.

Its the first member of the load-bearing structural systems. Also called the footer. This is where the house meets the ground. Its the first member of the load-bearing structural systems. Also called the footer. The footings are placed under all load-bearing parts of the foundation, i.e. piers, columns, foundation walls, etc. The footings are placed under all load-bearing parts of the foundation, i.e. piers, columns, foundation walls, etc. Pouring Concrete Footing Pouring Concrete Footing http://www.youtube.com/watch ?v=Mq4kE9BbKvc http://www.youtube.com/watch ?v=Mq4kE9BbKvc Slide 10
