WEEK 8 Joists

FLOOR JOISTS

Bearers already for marking out joist spacing, wall positions and where service waste lands. Marking position for timber is marked clearly with a bold line and a X on one side of that line. The X indicate that is where the timber is positioned.

Once bearers are all marked out, set the joist on the X mark. Sorting out where different treated timber and lengths are required in floor plan.

 

 

 Joist are all laid out and positioned with side of the house that is 15mm in from the outside edge of the bearer. This for the 30mm overhang of the boundary joist.

 

Once the 30mm overhang is positioned, check this with your stringline. Check the other side of the house and the overhang of the joist over the bearer will be 330mm to the stringline, then run another stringline -47mm from the 330mm stringline for boundary joist. Use a combination square to mark a plumb line from the singline, cut all joist to that -47mm line.

WEEK 7 Floor joists

FLOOR JOIST
The floor joists are sorted from the packet to see if the right lengths and quantity were delivered to site. The joist packet allowed for H3.2 joist in the kitchen.

Mark joist to plan and consider where walls land and service pipes will be ie. Toilet and shower waste pipes.

How do we provide a service area if a joist is in the way of a waste pipe?

WEEK 7 Jack studs

Once the sole plates are fixed into position, jack studs were nailed to the sole plate at 1600mm centers to the plans specifications.

Johnny and Arlee here cutting the jack studs to leveled height of the set string-line.

 

Once the jack studs are all cut to the -400mm from FFL, the bearers sat on top of the jack studs and fixed by two 100mm skewed nails to each jack stud, one each side of the bearer.

The jack studs and bearers are braced off and plumbed and measured for the correct width acording to the bearer plan.

What is the width from outside to outside of the bearers?

What is the measurement to the center.

If this is all correct, how would it make the next stage easier when installing?  

WEEK 6 Profiles and footing

BEARER PLAN

This shows where the foundation footings will be for the sole plates, jack studs and bearers to be positioned.

PROFILES
Building line has been set and footing lines was set also, for the Sole plates and Jack studs.

WEEK 6 Profiles

SETTING OUT PROFILES

Profiles are timber constructed frames to find the height of a finished floor level and the boundary of the building (house).

Profiles are a minimum of 900mm away from the marked peg (boundary of the building). 

PROFILE PARTS

Make sure the construction of the profile is sturdy, bracing will achieve this from moving. This is important when you start setting the string-line to find the building line it will not move and put the building (House) out of square.

WEEK 5 Start building the Unitec house

EXCAVATION

The site for the house to be built on was over grown with weeds and vegetation. This has to be cleared to reach solid ground and clear for marking out the location of the house.

 

The site is now cleared and looks a lot tidy for working on and marking out for profiles. This also makes the site safe from tripping over, standing on hidden sharp objects, twisting ankles. 

SETTING OUT LOCATION OF THE HOUSE

From the plans we set out the location of the house on-site, marking from the boundary of the property and measuring in from two boundary sides, we get the starting points to where the house is located on the site.

From here we can plot out the rest of the perimeter of the house using right angles from the formula 3-4-5. 

 

Depending on the shape of the house we can now work off these two sides and plot the building line of the house. Now we can set our profiles to each corner of the building line.

WEEK - 5 Site Safe

Wednesday 6th Site Safe

CCA1 Class completed the Site Safe course and enjoyed the session with Colin O'Gorman.
