Browse Forums Building A New House 1 Jul 25, 2012 5:33 pm Hi all, We have just been quoted $60K for siteworks plus $30K to have the concrete pool removed from a block which we are currently awaiting finanace approval on. Luckily, we included a feature survey clause in our terms of sale so we can back out if we need to. I would really like to know what the site works costs others had for their blocks, as $60K sounds extreme, but since I've never been in this position before I have nothing to compare it with. The block is 800sqm and has a slight (1.5-2m) slope to it. The main reason for the cost is because in order to fill in the slope, the block will need to be retained. Thank you in advance for any replies. Re: Site Works estimated cost 2Aug 29, 2012 9:08 pm Hi Oscar We have been discouraged from demolishing and building as the site works would cost "half as much as the house" - about 150K. I find this incredible and would love to hear from others. Re: Site Works estimated cost 3Aug 29, 2012 9:33 pm The details here are a little on the vague side so I'm ging to have to make a few assumptions, but given what you've mentioned above a few points spring to mind: A. 1-5-2m of slope isn't all that "slight" - you're going to be building on a decent amount of fill even if it's a vacant "virgin" block (our site costs were about $25k on a virgin block with a balanced corner-to-corner cut+fill on stiff clay - maximum height of fill was 0.8m in rear left corner), but having said that ... B. ... given that you're referring to having to remove a pool I'm thinking that the block isn't "virgin" at all (ie. it's had another structure built on it already). If that is the case then this complicates things as the earth will have settled beneath the footprint of the previous structure whereas the earth around it will not have, resulting in uneven compaction under the new house you're building and therefore reinforcement of the slab/footings in the affected areas (that is if the soil doesn't need to be dug up completely and replaced with clean fill). C. Depending on how close the pool is to the footprint of the house you wish to build we might be talking about disturbing subsoil which should be helping stop your house from moving down the slope (which may result in the need for deeper piers/edge beams). The retaining walls will be a significant contributor to the site costs, but they wont be the only large cost item I suspect. Some people apparently have nothing better to do than comment on other people's sigs. Re: Site Works estimated cost 4Aug 29, 2012 10:50 pm i would say the price you have been quoted is reasonable if not very cheap. i have recenetly built on a slooping block and the expenses keep adding. Cost to removal soil can be very high and cannot be planned for in advance. In additional as noted eariler depending on the location of the old pool and your new house you may also be up for peiring cost More concrete and excavation.. peiring may also be required even if the pool is not close. Best to seek advise from an enegineer or get soil test done you do not want a house that slips or moves to much.. A solution that i have used a few times now is by using "ultrafloor" as a way of addressing sloopiong blocks to achieve a level building pad. This provides you with a concrete floor and is quick and easy to deploy if done right. And don't forget drainage, pipes blue metal waterproofing of external walls etc etc good luck Hi Kristy Around $1.7-1.8m or around $4,600/sqm. if you PM me your email I will send you a break up in a spreadsheet so you can get an understanding of the costs for… 1 9925 Fair Trading can issue orders to rectify and complete but once the matter goes to NCAT these orders are automatically vacated.
