I need to have my driveway and back yard repaved. I'm not sure about the price of concrete per sq. ft. it's a 150ft driveway anf 50ft backyard. I also am going to have a deck with an arbor put on. Should I have the deck built first or the driveway and backyard concreted. I'ts the first project in a long time. Any advice

I don't know what part of the world you live in but the following information is pretty accurate for Southern California these days.

The average cost of ready mix concrete delivered to the job site is $110 - $135 per yard (cubic yard)... one yard will provide about 80 square feet of concrete at 3-1/2" to 4" thick. A job the size of the one you're describing will require a "pumper" and that can cost anywhere from $300 to $400 in addition to the cost of the "mud". If you're planning to build at deck you will need to dig footings for each of the posts... the size will depend on the size and span distances of both the rafter/joists and the header (distance between each post).

Also... you will have to factor in the expense of forming, grading the area and providing any sand or gravel base that may be required (if your native soil is expansive or swampy, etc.). Additionally, you will need to consider the labor cost to hire concrete finishers to help you get the mud on the ground and finish it before it's too late (the concrete hardens).

Don't try to cut corners on the help you plan to use... it's much too expensive to fix any mistakes or have the concrete "get away from you".

Good luck.
