Why this pipe is under the steel mesh?

Any thoughts. Why this pipe is still under the mesh . This is for the drainage from shower @downstairs powder room. i am concern if they cut it too short.

Waiting for the engineering for the slab to completed. In a meantime noticed the deterioration of foundation condition due to the weight of steel re inforcement. The mesh is bending /sagging at the edges and boundaries.

This is a pipe which was abutting to the slab has now been fixed. Thanks to the supervisor and my building inspector David seville.

Some of the bending and sagging issue noted by supervisor and supported until the ready to concrete.

This is the place from where PD has removed the drainage from alfresco but left the vapour barrier open and damaged. Supposed to be covered or taped. 

If looked at the top right hand corner , the steel mesh has bended downwards.

Steel mesh sagging at a different place.

support chair sinking in to the waffle pod due to the weight of steel mesh. As a result there will be less concrete between the mesh and waffle pod.

Another sagging issue.

This is a garage. on the top where the timber barriers are the whole mesh is bending downwards.

After building inspector raised it as issued. PD wrapped the drainage pipes but some how the wrapping is short lived and required attention.

Again another neighbour got their agi pipes properly protected with the sock. My one has left as it is by PD. There answer is the job will be done by the crushed rocks. Honestly i don't even know if the crushed rock is placed over it yet?

Drainage work done. these photos are taken on 23/08/2014.

I have covered it with the a shpping bag.

2nd week of progress

It was great to see the progress on the site. The site cut completed and concrete piers are poured.
There are 30 piers in total. I suppose this is due to the cut and fill done on the slope.

The concrete company in-charge of slab .

This pier is on the edge of the slab. the empoty space will be filled with the strip footing of 500mm x600 mm.

The membrane used as per BCA. it is pretty thick.

Agi drain. In my opinion Agi drain should be covered with geofabric , which will stop all the soil ,getting into the pipe. But PD said it will covered with the crushed rock which will work as a filter. God knows what is right.

Introduction

I am in a process of building my First Dream home in Melbourne North.
After reading lots of information about Building process through blogs and other article. I just completed an exhaustive journey of selections, changes and signing of My  Building contract. I thought it is a good idea to share my experience and journey with other people who may assist or require some information along the way.
So here I

am with my first ever Blog of my life and have decided to start with the Site start.

Untouched block a week before.
