concrete cutting
Anyone know an easy formula for bidding on cutting a trench in a slab. I am working a job and they asked me to cut a trench for plumbers. And to let them know what they owe me. I always try to be fair and competitive but I have not ever cut a trench like this. It is 6" concrete that is going to be cut one time 144' long. It is up against the back of a building and will be a 3' trench and I will have to breakup and haul off. Any advice would help Thanks.
ALLPRO,
Quick question: Is the 144' one way or 72' each side?
144' one way it should break away from building. it was an apron that was poured later.
Well depending what type of Saw Cutting Machine you use, whether hydraulic or electric, I would say about $6.00 a LF for the cut. Might call your local saw cutting outfit and see what they charge for inside saw cutting.
On the concrete side, I would say in the neighborhood of around $2-$5 a SF depending on a lot of factors, if you’re removing by machine or all hand work, how you get it out of the building.
Removing the concrete, it takes about 0.0147 man hour per square foot, plus load time. If you’re using a machine it will go down.
Any word on this AllPRO?
Thanks for the help. It was a small job so I sub it out to a plumber that was going to have to put pipe in. Thanks for the help.
how much time is 0.0147 per man hour?14.7 minutes?
It's approximately 1.5 minutes per square foot. This does not include equipment or load out.
I just tonight put a bid in on about 350' of 18" wide trench (4" thick) as well as some other items. I got a quote of $1 per linear cut foot , so that would be $700 for the trench, plus $1.50 per cross cut. It will be inside with a slab saw. $6 a LF sounds crazy, but if thats what you can get all the power to ya!
Well you got out cheap. Places around here usually charge between .50 - $1.00 per inch foot. So a 4" slab cut would be between $2.00 and $4.00 a lineal foot.
A $1.00 per lineal foot is cheap and I mean cheap. If that is true, your getting a killer deal. I don't know how that company will make any money. 700 LF is a lot of cutting. I would like to hear how this one finishes out.
