Demo approval is simple enough, intervals, as you know, is a totally different ball game.

Very true NRG37+ Just wondering, what have been your experiences with M's accuracy in predicting stormwater and BASIX costs, ie how close was their actual cost to their provisional sum? We just received a variation for our stormwater and BASIX items and it ended up being 30% more than M's provisional sum. We didn't budget for this significant sum and feel it's a bit unfair for M to slap this on us after they submit to council with all the hydraulics and BASIX reports so we can't really complain without affecting out DA after application Would be good to know what people think here about provisional sum vs actual sum re stormwater and BASIX

Good question Q, made me think.

Provisionals;

Stormwater disposal-$20,000
BASIX- $10,000
Bushfire (BAL 12.5)- $7000
Rock removal- $10,000
Traffic control- $8,000

Actuals;

Stormwater disposal & BASIX- $11,287 refund
Bushfire (BAL 12.5)- $2594 refund
Rock removal- TBC
Traffic control- TBC

I expect to get most if not all of the money back for rock and traffic as it wasn't ultimately needed.

Ours was a bit all over the place, originally 20k provision for stormwater and 10k for basix. Then changed stormwater provision to 5k and I questioned what caused the big drop and was advised it wasn't final. Then final cost came in at 11k for stormwater and 10k for basix.
Still don't know why they changed the provision from 20k to 5k but final of 11k is better than 20k

Thanks guys, I'm just feeling a bit sore about being charged $6.8k for a 6800L above ground rainwater tank, $3.5k for gutter protectors, and $27k to implement the hydraulic engineers' stormwater system. Our provisional sum was $23k for stormwater and $10k for BASIX, but we are being hit for a $10k bill on top of the provisional sums

Damn that sux!

We were
Provisional sums:
Stormwater disposal- $20,000
BASIX- $10,000

Actuals:
Stormwater disposal - $16,359
Gutter Guards - $5,180
Additional Concrete & Drop Edge Beam for Rainwater Tanks - $6,562 + $592
Rainwater Tanks (x3) - $4,416 + $6,079
Recycled Water plumbing - $2,210

So in total our actuals were $11,398 more than the provisional sums

Thanks Aria, you are in Ryde?

Yup

Thanks Aria, I guess we just live in an area with higher than average stormwater system requirements

Haha the stormwater/basix requirements have been the most painful part of the administration part of the build for my husband lol

Yes, Ryde makes you do "stupid" levels of stormwater detention. Costs a small fortune here.

Lol I was just looking at my variation again and realised we have 3 x 5960l tanks .... Meaning a total of 17,880l!!!!

One up you. 3 6k litre tanks and 1 2k:):)

Haha your house must be a lot bigger

Any idea what factors in to calculating storm water disposal?

Our provisionals were $25k - came in at $22k. BASIX $10k - came in at $11k.

Based on the differences evetyone is quoting above, how can they vary so much for similar sized homes (excuse my ignorance if this is glaringly obvious)??

One 5710 L tank for us. Aria are you sure you need 3 tanks, could it be an admin error?!

it was on the osd/basix report that went to Council

Our land slopes slightly from front to back so I think that's why we needed heaps....lol my husband argued with them about why we needed so much but apparently that's how it has to be it meant we had to make his study smaller as well to accommodate for the rainwatertanks

I guess we should seek comfort that our houses shouldn't wash away as easily from storms with such a robust stormwater system..lol

Aria, is your husband called Noah by any chance?! Last time we saw that much rain, we had to save the animals two by two
