7AM - Marsden Park
Site prior to benching (levelling and compacting)
Let's roll!
Hi I'm Warren from Kaplan Homes,
today we're gonna take you through an early stage in construction:
site excavation.
Here we have our D939 Cat which is gonna help us bench the site.
So prior to starting here we've got the laser set up over there which is gonna
give us the heights of our benching platform.
The surveyors have already been in
you'll notice the four pegs in the corner
which gives us the exact location
of where we're gonna build the new home.
Steve's away here taking the top level off the benching platform
and then we'll start to dig in and get our levels right.
So you can see that Steve's now stripping off all the vegetation
and its important to make sure we don't have any vegetation in the cut
any material that can break down whilst we're compacting the slab.
We're starting to get down now into the good dark clay
which will all be spread around and evenly packed.
We're down now to about 300(mm) which is roughly what we want for our benching height.
We'll relocate the material, compact it with the D939
which will compact it to the level we we want and then on
will come the tractor to get the levels right.
So here we are, we got the tractor set up.
He's got the dumpy levels just adjusting it on the tractor there.
You've got the levels which will adjust the blade
and get us the the perfect level of what we need.
So now he's just gonna drive round and round and round in circles...
So now we're gettin' closer to our benching level,
we've had the tractor out there and brought it close to the level.
Now we're using the D939-C
to compact the benching platform
to the density we want and get it nice and solid.
The machinery going back and forth along the benching platform
to make this pad harder than the road.
As you can see the benching platform's now finished
and with the twelve and a half tonne machine
it's as hard as its ever gonna be.
The site has now been compacted to a laser-checked horizontal level.
