In what circumstance would a project home builder specify screw piles? Is it due to soil classification test? I thought it was odd when I saw them... Also what are the 3x trenches for? This is sitting underneath the main bedroom on the low side of the block, however when I say low side of the block the contour from left to right is a total fall of ~1m Note that this perimeter wall will also be the location for the rainwater tank 5000L and aircon unit. Is it reinforcing for the weight of the rainwater tank? Re: H Slab - Screw Piles 27Sep 23, 2019 8:41 am Snowlaina_80 Thanks for the advice. In what circumstance would a project home builder specify screw piles? Is it due to soil classification test? I thought it was odd when I saw them... You're Welcome The engineer specifies the footing details and piling, not the builder, piles are used in a number of instances, uncontrolled fill, differential settlement, building adjacent to sewer lines,etc Snowlaina_80 Also what are the 3x trenches for? This is sitting underneath the main bedroom on the low side of the block, however when I say low side of the block the contour from left to right is a total fall of ~1m You are familiar with the plans, looking at the geotech report, engineering footing/slab details and on site taking photos several times a week during the entire build? when asking for advice photos only take you so far and more info helps (the better the info the better the reply, this also helps others) Try putting up the site photos with images of the plans /engineering, delete the builders info or Leave a PM It saves guessing or receiving no reply at all I always tend to comment when I see a red flag..that's just me.. trying to help out the Battlers & Punters Snowlaina_80 Note that this perimeter wall will also be the location for the rainwater tank 5000L and aircon unit. Is it reinforcing for the weight of the rainwater tank? Possibly, the water tank will require a raft slab.

As mentioned it's not my build, its a friend of mine so I don't have the geotech report or the full plans on hand with me. I've only got a contour plan with what looks like a peg out plan & the RL levels on it. I will try and catchup with them ASAP and have a look so we can review what you've mentioned. I've previously built, hence why I'm aware of documenting all stages of the build and been to the site weekly to take detailed photos. Just can't be too careful Re: H Slab - Screw Piles 29Sep 23, 2019 11:17 am StructuralBIMGuy The engineer specifies the footing details and piling, not the builder, piles are used in a number of instances, uncontrolled fill, differential settlement, building adjacent to sewer lines,etc The RHS boundary has a concrete encased sewer line running the full length of the block just off the boundary Re: H Slab - Screw Piles 30Sep 23, 2019 1:49 pm Snowlaina_80 StructuralBIMGuy The engineer specifies the footing details and piling, not the builder, piles are used in a number of instances, uncontrolled fill, differential settlement, building adjacent to sewer lines,etc The RHS boundary has a concrete encased sewer line running the full length of the block just off the boundary The screw piles may be for the angle of repose regarding the sewer line as it may be to deep for conventional bored piers. This will depend on the depth of the sewer pipe. Screw piles can go much deeper than conventional bored piers. Just a guess but should be of the engineers drawings.

That basically means that the villa board is glued to the brick wall with… 3 8311 Thanks for the insights, that makes perfect sense, and yeah, I will be leaning on the experience of the excavator operator entirely. 6 16147 4 6201 |
