Started today in class working with Rich on our assignment 4543, going over questions in moodle and parts of the calculations. Soon after headed out to the site to finish pluming the corners & sides of the wall frames. We also ran string lines with a dodger block being our length of our top & bottom plate to the string line, the top and bottom plates were then moved to get an accurate position of the walls. We used bracing timber to brace the walls, once it was plum we would hammer a few nails into the brace to the wall till the top & bottom plate was in the correct position. All though we done some good work through the day progressed.

Flooring
3.2.1 Explain using photograph’s, notes and sketches how the flooring was laid on the Unitec house.
You must cover: The type, sizes, direction of sheets, gluing requirements, cutting, nailing patterns, care, lifting, Health and Safety, etc. Include all fixings information as well.
Placing the particle boards, we had to find the full length of the joists and mark the middle. Then came out 800mm from the middle, we had to do this on both right and left sides of the middle mark. This mark is used for string lines to help guide the silver insulation.
Once the joists, and nogs are done. We then needed to use a planner to get the joists all plumb and levelled.
We also created a mechanism to give 100mm slack for insulation, for the floor of the house.
After laying down the insulation we then had to cut out 4 to 3 squares for a place to set the glue for the boards. This was 300mm spacing from each square on each joist.
Eg, of the glue placed into the squares cut out, only problem is that the glue sets within a 10 min period so you have to be quick placing the boards before it sets.
After the glue is placed you then will need to lay your boards 200 mm away from the 800mm, because the size of the boards is 1200 mm wide.so the measurements for the board is 600 mm out from the middle.
To fuse both boards together and getting a tight seal, you will need to glue the sides of board and place them side by side. Use a chisel, and hammer it on the sides to the joists and push the board into the spot where it is getting sealed with glue. Making sure that the board is plumb and equal, you then hammer the boards down with nails.
Piles, Joists,Bearers
3.1.1 Explain using photograph’s, notes and sketches how you would set out the temporary piles, bearers and joists.
You must include: Measuring, straightening, cutting, joining, nailing, selecting the timber, cambers, etc.
Jack studs are cut and placed at measurement where both jack stud and bearer will be equal for the finished floor level.
Each jack stud is braced off on the sides on a 45 degree angle for extra support.
We then used H 3.2 exposed timber for the bearers, laminating each one together till it was plum and level.
Using 100 mm galvanized nails to laminate the bearers together by marking up and lining up 60mm outside from the width of the bearers and 250mm spacing from the length of the bearers.
Placing the bearers on top of the jack studs, and hammering 100 mm galvanized nails into the jack studs.
Nailing extra braces to the jack studs, bracing across the jack studs to help support the weight of the building.
Joists are measured according to the house plan and cut out to be placed on top of the bearers at a span according to NZS 3604.
There were different timber treatments we used in different areas of the joists, there were highly treated timber were we used in the wet areas like the kitchen, bathroom, toilets and used the less treated in normal parts of the house.
Once the joists were layed we then used nogs between the joists.
Profiling
3.1.1 Explain using photograph’s, notes and sketches how you set out your house site using profiles.
Cover: datum height, profile pegs and boards, string lines, Builders dumpy level and laser level, how to level batter boards, squaring up the house footprint, checking diagonals, etc.
Builder’s Dumpy level
How to set out your house site by using profiles is firstly you would need to locate the datum points and the boundary pegs to figure out your datum height, after it is located you will need a dumpy level to figure out the height that you will be working off, and then run a string line along the outside of the boundary pegs to mark out your site.
Boundary pegs
Position profiles 900mm -1mm from outside of the building lines or whatever it says on your plans.
After positioning the profile pegs, you will have to calculate the finished floor level from datum and transfer the finished floor level to the braced pegs.
Batter boards are then attached to the profile pegs according to the F.F.L; if it’s not levelled correctly it can throw your whole foundation off. leveling the batter boards you will need to check if the pegs are plum and level to the ground floor.
Once your batter boards are in place and leveled, you then hammer a nail on to your batter board. Sighting across to the next of your other batter boards, add nails on each end. Then run your string line down the length and the width to each corner of your batter boards. This will locate the corner of your foundation.
Rule a tape measure and measure the corner points of the string line diagonally corner to corner to whatever measurement that is required. You should then have the same measurements in both directions. If it’s not, you must then move both nails to the measurement of one end the same amount of space until you reach your square number.
