Foundations for new dwelling quote

[nowtie]

Hi,

I'm in the SW. Just received a quote for the foundations of our 156.5 sqm dwelling and am looking for expert opinions. It seems on the light side and not much detail. What questions should I go back with? Drawings and spec attached 

 

1. Mobilisation of labour , plant and materials to site per rig, per gang. £650.00
2 To construct traditional foundations over a total maximum combined 63m, allowing for a maximum excavation depth of 1500mm from site
level, width 600mm and 1000mm depth of concrete. Concrete strength 35N £18,648.00

3 Additional depth if required hr cost +15% Rate only
4 To remove excavated spoil and any waste material off site Item cost +10% Rate only
5 Take and test 3No. Concrete cubes as instructed. £250.00 set Rate only
6 Standing time for reasons beyond our control. £160.00 p/h  Rate only

Total: £19,298.00

 

In preparing our quotation we have allowed for approximately 63000mm of traditional foundation. This allows for excavating a maximum depth of 1500mm from site level, 600mm wide and for maximum depth of concrete 1000mm.

We have assumed that the following will be provided:

1. Setting out. (We can arrange a Setting Out Engineer at cost if required)
2. Site welfare. (Water, Electric and WC)
3. Removal of excavated spoil off site.

What more are you expecting 

they are quoting to dig a trench 1500mm deep 600mm wide and fill it with concrete, to a depth of 1 m. 
 

you are doing the setting out

you are paying for muck away

 

concrete cost is about £5000. 
for a company with its own large excavator and a couple of dumpers it’s 2-3 days work. 
 

there’s probably not much detail as they want to get a feel from you first, detailed quotes take time, if their busy they haven’t got the time to mess about until they think your not a time waster.

It is what it says on the tin

Nice quick job 

 

Ask about grading the site  Drains Treatment Plant if needed 

As Russel says Detailed quotes are time consuming 
Its a start

Much better than I got, simple and straightforward. Sounds like a small business managing their time and risk.

You might want to get all the other basic ground works jobs done at the same time. Services, drainage, hardstanding areas, etc. Unless you intend doing those yourself with your own machine?
