• measured the distance between the purlins for the raft wings to go under each purlin keeping it strong. top plate of the side frames we measured the space in between the raft wings and put nogs which were green treated timber in between them sticking side by side but above the top plate of the side frames. for the nogs sticking out of the front frame we used the pink treated timber because it was water resistant and was the correct treated timber to use. the sized nogs we used was 90mm. and then we used 4x4 nogs in between the rafts (view from the front) to keep the rafts from twisting and to give it that extra strength for the roof.

• purlins were stagged and nailed on top of the rafts and nailed in to prevent the rafts from twisting. Put up a Metal and wooden scaffolding to reach the top of the house. Before bracing we used the spirit level to make sure the vertical parts of the scaffold were plumbed then we braced it with long pieces of timber to avoid the scaffolding from rocking or falling over. Spaces between each raft was 751mm. Made a string line across the width on top of the rafts as a guide for the purlins so they could be nailed in a straight line. made scaffolds in the middle of the house up against the back wall and braced it to the walls with timber under the braces for more support.

Reflection on the Profiles

1. Profiles/ Ground plates

• Name the parts and explain their functions/purpose?

Profiles: to set the boundary line and the mark the height of the batter board by using the telescope to set the measurement on the the measuring stick.

Ground Plates:

• How do we set them up?

By nailing them into the ground with a nail gun and making sure the profiles are braced.

Piles/ Bearers/ Floor Joist

• Types of piles as per plan and their functions?

 doubling timbers and hammering the nails on a 45 degree angle so it prevents it from sliding and creates a stronger support for anything that goes on top of the bearers etc.

• Fixing requirements for pile to bearer and joist to bearer?

skewing the nail on a 45 degree angle and nailing it from the side  of the bearer down to the pile.

• What are the spacing requirements for the following piles and joist?

90mm from the sides then 600mm between each joist.

• What is the living space area?

Wall Framing requirements

• Find the length of walls A,B,C,D?

• A wall has structural components. Name all the components and state their functions?

Trimming studs: marked at the width of the window and upholds the window.
Studs: holds the top plate. keeps the wall frames strong vertically.
Nogs: keeps the spaces in between the studs and stops them from bending and creating a bow.
Solid blocking: keeps the studs straight and prevents the studs from twisting.

• What timber treatment is the bottom plate and why?

H3.1: because its water resistant and the bottom plate is closest to the ground.

• How do we set our wall frames? Use HBG Branz book to help answer the questions?

• Which nogs do we cut and nail later after we build our frames?

• what are the nailing requirements for the wall frames?

* Studs were squared off on one side and cut on a 6 degree angle for the top plate(roof).

Bracing requirements

• how can we identify bracing elements from the plans?

by locating the BL1 on the plans.

• why did we fix bracing straps on the trimmer studs and the lintels?

because the trimmer studs and lintels support the windows and will help prevent them from sliding or coming out and also prevent them being one sided.

• how many nails did we use and what nails were they?

4 on the top 2 in the middle and 6 on the bottom. 30x2.5mm, galvanised nails.



Roof framing

• Name the two roof framing members that you placed on the roof today?

Rafts and Purlins

• At what centres were they?

Rafts: 600mm
Purlins: 751mm

April 11

• We replaced the studs with longer ones and the nogs in between them with the correct sized nogs. then we learnt how to put up scaffolding step by step and learnt that they were used for reaching the height of a roof while it was secure with decent space. On the top on the ends of the top plates of all the frames we applied a silver plate that combines the two top plates together and hammering the groves down so its resistible when it tries to widen.

•  Then we went to go plan on how to build our roof and used the Building book to get our information from it and identify the steps we needed to take. Before we started on our roof our team had a little meeting and organised ourselves and splited up into pairs to get two jobs finished before the day because most of our team was gone and there was only for of us. So two of our team mates started on the rafts of the roof and me and other team member started on marking and chiseling 3mls off the timber and then nailing the stainless straps in them. We also marked and sawed small studs to hold up the ends sticking out of the house so it doesn't drop and cause the stud to disconnect from the top plate.

April 6

• We put the perforated aluminium foil over the joists of the floor and let it drop at 100mm between each of the joists and then nailing them in at the joists. Safety of the perforated foils is to wear sunglasses on sunny days because of the strong reflection it gives. Then we applied the ply wood on top for the flooring as staggered sheet joints and making the edges match T and G (tongue and groove) flooring with no gaps. Then we nailed the floor into the joists with galvanised jolt head nails. Nailing edges of sheets at 150mm crs and nailing the intermediate joists at 300mm crs.

• Then we nailed timber that was 90mm thick on the ends and middle of the bottom plate sticking up as a stop for the back wall and as a spacing guide. Then we lifted the back wall onto the floor and braced it on each side to the bottom of the bottom plate to the top of the wall. We lifted the frames up onto the floor and placed them in the places they were suppose to go in and braced them from the bottom of them to the top of the back wall. And the last wall we lifted and braced across the face of it (temporary braces). Then we made a string line going across the bottom plate and used a measuring block to check if was the same thickness as the spacer block and to check if the top was plumbed we used a spirit level and placed it on the corner of the back wall and frames and when they were plumbed we nailed the brace in the inside of the walls and frames. After that we cleaned up our workspace and went inside the workshop and planned and talked about what we going to do next week and how we were going to fix what needed to be fixed before we moved onto our roof planning.

• Overall as a leader i found it challenging. What i found challenging was trying to understand what to do on the first attempt and trying to keep my team organised by giving them tasks to do while doing them myself. But as i listened the second time my mind was starting to click more easily by trying to picture it in my head. One way that made it more easy for me to understand of what to do in each task we were given to progress in our work was reading the House Building Guide if i had listened and red this book earlier i would've been clued onto what we were doing in each step of the way.

• wall framming
• roof and ceiling framing
• sub floor jack framming

At what height did you place your lintels and why?

• 2mters 10

What points did you consider when setting out the wall frames?

• 
  

At what centres are the..

• Nogs: 800mm
• Studs: 400mm

How many nails did you use to fit studs to the bottom and top plates and what size and finish?

• 3 nails hammered to the bottom and top plates
• nail size 90 used 
• 
  

Subfloor

Why did we use solid blocking?

• to keep the joists straight and prevent them from twisting when it rains and absorbs moisture then dries up from the sun. 

Describe the nailing pattern for the sheet flooring..

• Perimeter: nailing edges of sheets at 150mm crs
• Intermediate: nailing to intermediate joists at 300 crs

April 4

• The first week of April and the week i step up to the plate of becoming leader. The things i found challenging about being leader was not do you only have to worry about what you do and how you work but to also make sure everyone else has something to do and that their doing there job correctly. first by making sure that we construct the frames fast and accurately. by the end of the day we finished both walls A and B but with different measurements for the windows.

• The studs and trimming studs we marked had to be angled off at the end at 6 degrees so that the roof can be on an angle when it goes on top. The length of the window on wall A was 410mm leaving the extra 10mm for the gap and the width at Lintel . For the small window at Wall B it was measured at 900mm.
