Browse Forums Building A New House 1 Nov 19, 2015 9:56 am Hi everyone, I would really appreciate some opinions about the site costs for our new home tender which we received last week. This is how it appears on our tender: Engineering costs -Provide Structural design for home: $2048 -Provide M or H class slab (as required): INCLUDED -Allowance for up to 80 lineal metres of concrete piers including Drill Rig and Pump Hire: $3980 Site Costs -Site excavation and preparation for the concrete slab (up to 500mm fall over building envelope). Excludes removal of excess spoil: $2925 -Connection to electricity supply: $3187 -Sewer drainage connection: $2048 -Connection to ground water: $731 -Provision of concrete pump for piers and slab (2 visits): $2194 -Stormwater connection: $2706 -Gas connection: $1024 -Site management: INCLUDED Provisional Allowances -Drop edge beam if required: $6962 -BAL requirements if required: NOT INCLUDED -Retaining walls if required: NOT INCLUDED -Scaffolding to front facade due to sloping back: $1097 -Spoil removal: NOT INCLUDED -Extra soil over requirements for waffle pod concrete slab in accordance with council and/or engineering requirements, salinity soil testing: NOT INCLUDED Statutory/Council Requirements and Standard BASIX Requirements are there and listed separately as certain costs, INCLUDED, or NO CHARGE next to the relevant items. SITE COST TOTAL: $35,660 (Cents are listed next to all the totals but I have omitted them for ease here). Our land has a sloping front and we're doing cut and fill. Reports came back saying that it needs an H class slab. Single storey only. Building in an area which is predominantly clay under the ground. Are these site costs too much? Is there anything missing? Is there anything fishy? Please let me know your thoughts! Re: Site Costs question 8Nov 19, 2015 1:04 pm We will be building a 27sq house in Vic, single storey on a sloping block (2m slope from side to side) with an M class slab (with engineering), retaining walls, etc - our site costs are just over $37,000.00. So your amount sounds pretty right to me (but then it is possible we are both getting duped... ) My blog: tashandpaul.wordpress.com Re: Site Costs question 9Nov 20, 2015 8:52 am Are you going with a project builder? or a custom home builder? I have been talking to some project home builders and some advised that they will provide a upfront price and not list it as provisions. So if they hit a major rock or extra piering then it will be their cost. Have you approach one of those builders? for example, Rawson homes does it. which builder are you with? Re: Site Costs question 10Nov 20, 2015 9:18 am Hi Guys It is impossible to tell if you are being overcharged why. 1.If you work the prices backwards they relate to Quantities ( ie,Nos, m2,m3 etc) multiplied by Rates (ie, Item$, $/lm/$/m2,etc).. you have provided neither, just ambiguous totals no other details. 2. If you compare totals with other projects, are all the variables the same..No? 3. ..as was stated are you all being duped, that is a good question? The correct process is as follows A. From the plans/Sketches, quantities are derived B. The builder should discuss various options,costs and build implications and from there you should should pick the optimized solution C. This whole process can automated through 3D drawings and BIM, yet clients seem to be only concerned with renderings and can the roof colour be changed in the Design Image ? D. Clients need to insist on better Site/Design options and engineering...Do the Talking with your feet..walk out if they aren't going to give you what you want and go to someone who will..they'll soon change.

If not , be prepared it will change sending on your cut and fill Re: Site Costs question 13Nov 22, 2015 7:56 pm zc12345 StructuralBIMGuy, are you saying that the builder cannot give a true site costs until plans are drawn? btw, where are you based? You would think the builder should be able to price the true site costs? But sometimes its easier for the salesman or builder to blame unforeseeable factors and the clients has to pay more (Sticker shock?). Top excuses 1. We didn't have the engineering back then and there is now (down the track?) a problem... " WT%$^#"? 2. We aren't experts (engineers)..the problems were unforeseen at that time? 3. You (client) didn't want to spend money upfront, LOL Blame shifting? 4. What would the salesman know he's not a certified Geotech Engineer? 5. We made a mistake..etc,etc Unfortunately you have to ask the questions and seek the answers yourself beforehand (caveat emptor comes to mind) This forum is a great resource use it wisely, Here's what I would do in your shoes. a. Get full copies of all the plans, engineering, siteworks, geo,etc,etc b. Work out a fair price for the items based on materials, labour, plant costs and Builders Margin c. There is also parametric optimization software that can do this and analyse all options d. Also get independent quotes and compare them e. Armed with all this information, then try to negotiate a fair price if necessary, but somehow I think you have gone past that stage. Finally I am in Perth and Take this from me I've got my hands full structurally repairing relatively new projects/homes, most (clients) are paying a high price when you analyse the data/costs so expect more of a service from your builder/contractor than the average " we'll fix that up later when the need arises " sorry for the rant Designer,Engineer (Civil,Const & Envir),Builder,Concrete & Masonry Contract.Struct Repairs I am not sure whether Perth has its own way of doing things in regards to this. Most of Perth has class A (sandy soil), except for some areas near rivers or hills. 2 13098 Is anyone building with Mojo and have a recent site cost tender 0 15952 Henley should give you some indication of site costs. Too many variable to give you any reasonable accuracy 1 1882 |
