Today we nailed the last of the piles down,We re-checked the spot levels on the sole plates and they were level.After that we installed the bearer to the top of the piles.Bracing was nailed to the piles so we could get the bearer level.A string line was put on the side with a block of 4x2 at each end and run another block down the line.Once these were all leveled,the barrier joists were nailed on.Our diagonals were out by 5mm so Matt and Cam Hit the bearers and got them to 17.091 making the bearers all square.We then started cutting up the joists,so 45mm at each end taken away so (90mm in total) from 7200 making the joists lengths 7110.To get the amount of joists needed,15500 length of the building divide by 450mm=34.4,rounded up to 35 and another one added for the one for nothing,so 36 in total.We managed to get all the joists cut to the correct lengths and tacked in place.Me and Brad started installing the blocks for the walling.The blocks width are 140mm,and we were to have them centered at 600mm,670 for the first measurement then used the running measurement to carry on,670,1270,1870 and so on.

Joists being put in place.

Joists all in place,along with blocks.

Our results for the day.

The blocks were made up for the potential manhole,The joists were cut and a square structure was nailed in.Next time we are back at tech we will be strapping the joists into place making the structure stronger.

Blocks for walling being installed.

The powertools I used today were;Nailgun and Radial arm saw.

Bearers being shaved then Joists being installed.

Before using the radial arm saw I checked around for potential hazards,such as off cuts,nails,anything that could get in the way whilst using the saw.I wore eye and hearing protection.I also never leave the saw untill it stops spinning,that    
way I know it cannot harm anyone.





When using the nail gun,I wore ear muffs and nailed into strong bits of timber,not to close to the edge causing the nails to fly out.I also made sure nobody had their hands in the way.
