Gonna have a 16 x 25 addition put on and need the foundation dug/installed

1. more or less flat area
2. just need the 4' underground of block plus footing
3. would prob need some of the interior dirt removed for a small crawl space.

any sort of estimate would help in planning.

thx

Get some bids!!!
Here in the northeast concret is $60-75 ayrd delivered!!!
You can plan on double that for a "poured/ finnished price per yrd!!!
if you or a friend have operated equipment than you could rent an excavator and dig it yourself
watch out for underground utiities phone,gas water electric cable irigation septic ect!!!
DO NOT LET HEAVY TRUCKS OR EQUIPMENT DRIVE OVER YOUR SEPTIC TANK OR LEACH FIELD
iF YOUR DRIVEWAY IS TAR PUT DOWN 2X6 OR WIDER BOARDS ON THE EDGE OF THE DRIVEWAY SO YOU DON'T CRACK IT!!!
If digging is easy a 4-ton machine will dig it in a day easy what is your soil like???
Rocks???
access???
Is the ground frozen???
You will need a machine again to backfill your frost walls to do this right you should also "compact the soil both under the fondation and while backfilling the sides!!!
Is it wet???
Do you need a curtain drain???
An excavator to rent can cost $225-$500 per day
To hire someone you will pay$50-$125 per hour!!!
A skidsteer might work better for "backfilling but an excavator will work fine also!!!
Sometimes you can rent a skidsteer for $150 per day!!!
GOOD LUCK
BIG
