The following is one estimate I received for concrete flatwork to replace the crap the builder installed. This is the highest bid, the lowest was around $12,300. What is mentioned in the estimate is based on specifications and a drawings I submitted to three contractors. Unfortunately we can't afford to do this project, so it's on the back burner...maybe next year.
PHASE 1:
Tear out and remove existing concrete driveway apron leading in off the asphalt street.
Area is: 270.5 square feet.
Remove 2" (+ or -) of the surface soils, to allow 6" depth.
Remove dirt/gravel areas behind the concrete, to lengthen the driveway back to the South.
Adjust landscape materials along the East side of the concrete, over and around the culvert
pipe, to allow water to properly drain from the concrete into the ditch.
Compact and fine grade loose soils.
Form and replace the driveway area, at: 446 square feet.
Concrete will be replaced using a city/county approved six sack cement mix,
with a minimum compressive strength of 4,000 p.s.i.
Concrete will be poured at a six inch thickness, with #4 rebar set at 24" on center
running East to West. Rebar will be placed on chairs to assure 3" coverage on all sides.
Edges and joints will be tooled.
Barricades/traffic cones will be provided for protection.
Broom finish.
