So today,I cut the final piece of facia.I had to put blocking off the soffiet bearer so I had fixing for the join for the facia boards.Primed up each end.Then sat it in place and used a hand drill to predrill the holes for the jolts.Now the final soffiets can be set up and finished.I then moved on to the second to last window of the house.Used flat heads to sercure the flashing down to the sill of the window.We had to roll over the edge of the flashing as the space we had was a tight fit.8mm packers were used at the left hand side of the opening with 5mm at the other end.I used a straight edge spirit level to get the sills all level then put the final packers in the last slot,After this it was all screwed off.My rule was used against the edge off the sill and the face of the wall,this was done as the gib is 10mm thick.

Nailing off a beam for our scaffold.

The Standards and putlogs and blocking.

After lunch me and the other half of the class went on to making our own timber scaffold set up.Ours is 6 metres in length.The set up contains components off;Putlogs,Standards,Kick rail,mid rail,top rail and 4 rows of scaffold boards.These have to be set up on a building site if the building exceeds 3 metres in height.This is to ensure that we as the builders are safe for when it comes screwing off the iron sheets for the roof.The kick rail is there to prevent tools,paint,power tools,basically anything that is sitting up there.

In our morning session upstairs Matt taught us about what materials that can be used with each other,Metals and plastics for roofing.And other things around the house,I never knew how badly corrosion can be untill I looked at the chart we were given stating what can be matched together and what can't be.Plastic can be attached to a roof of corrigated gav iron as it can rust it.The minerals in each metal can have a positive or a negative effect on each other.It is important to get the right materials for the right job.

Matt taught the class about how water can get into an external wall on a house or a shed.Whether it be weather boards or iron cladding.There are 4 ways water can get into a wall.

-Capillary Action.
-Kinetic Energy.
-Surface Tension.
-Gravity.

Wind can push the water up into the cracks or grooves in the weather boards or iron cladding.Gravity lets the rain run down the boards on the outside,Whilst Capillary action is when water is obsorbed and seeps it's way up through the timber.There are 4 ways to weather proof a house or building.They are known as the 4 D's.;Deflection,Drainage,Drying and Durability.

Materials that have absorbant properties,Bricks,Clay tiles,Stone,natural roofing and twitch.These obsorb water,while the remainder of the water drains down the face of the materials.A ventilated Cavity allows the water that penetrates the cladding to drain down the inner face of the outer skin.A water proof wall wrap acts as a second line of defense against water ingress,A wall wrap must breath to allow vapour to escape.

Ceiling Battons.

After the small session in class.We all vacated back to the house build.We started fixing the weather boards to the house,Matt made up a guide as to where the chalk lines were to be snapped to on the wall wrap.Then galv Jolt heads,75mm were used.All the joins were mitred.They were directly fixed as the soffiets were 600mm wide.Therefore no cavity batton was needed for the build.Most of the ceiling battons are now installed.They were spaced at 600mm centers.As the Gib boards are 1200mm wide.The windows arrive this Friday ready for us to go ahead and put them in.We will also be finishing the remainder of the facia and soffiets then onto the rest of the weather boards.

We started off in class working on a subject,Scaffolding.And what it is used for ect.Scaffolding is set up on a building site around the construction or erection of a building.It is very useful for us as builders needing to work on high points of the build,For example,Me and Brad used portable scaffolding on each side of the house.We needed it for the installation of the outriggers for our soffiets.

There are many parts to a scaffold set up;Ledger,Standard,Hand guard,midrail,Kick rail,putt rails,Sole boards.These are some of the components involved in scaffolding.

Aluflex which was attached to the lounge opening.

Aluband along with the plastic corners.

Aluband.

Soffiets.

Once we got back to the E Shed.We went ahead with facia.We got our entire side done,Then we moved onto one of the 7.2m sides of the house,turned out the outriggers were all different lengths,So we had to remove them and re cut them to the correct lengths,A dodgem block was set up as well.A spirit level was used to level the outriggers in place.Then used a nail gun to fix them to place.A few of the other groups were setting up ceiling batten,for the inside.While another group is doing the soffiets.Cement board ws used.200mm centers for the nailing with nails to the soffiet plate.with a nail into every outrigger.Flat head nails were used.Regan and Tom were laying down aluband,Plastic corners were also nailed in before the aluband was laid down,Add 200mm to the bottom length of the band at each end,so 400mm in total.Then clean the surface it is being attached to.After this remove the film on the adhesive surface then place it onto the building wrap around the buildings openings.Once this is all laid out,attach a stip of 50mm by 100mm to each of the corners on a 45 degree angle to prevent the tape from moving or coming off while continuing with the build.

So today,We started off with a small blog session in the e shed.I then went back to the house build after and finished doing the bracing for the corner/Hip purlins,I cut them on a 10 degree slope with a 45 degree angle cut.I nailed them off with a nail gun using 4 inch bright galvs.

Facia going up.



Wire stapled down to the purlins.



Me,Brad and Takey getting the facia to the right height.

We went back into the E shed after smoko to endure a 2 hour session of assessment related work on the laptops in regards to the Roofing section of the build.I basically have caught up with most work and have passed all standards so far.After 12pm me and a few others started with Facia.This was my first time doing it,The end of the Facia was cut on a 45 angle and the top of the inside groove was to fit flush with the bottom of the outriggers that are attached to the Soffiet bearer.I used my rule to slot into the grove and sat it flush with the outriggers.I used a electric drill to pre drill the holes for the 3 inch galv nails.We worked our way one out rigger at a time.After each one we sighted it down the other end.Each end of the facia was coated with a selant to prevent rott in the timber.
