Bridge Blasting


Hey guys, I went today and looked at a local township bridge they want done. The bottom beams underneath they want blasted and painted.

Here is some pics. Any idea how you guys would bid this? the one side i can do without having to much of a problem. My idea is to contain all the sand with tarps and bringing fresh air in, filterd air out.

The other side there is a stream running through, they just poured new concrete and the forms will stil be there. My idea is to build a platform to work off of. And plastic to contain from getting into water.

This is my first job to do like this. Anyone have any advice. I really dont think its going to be to hard. with the idea i have of doing it. Anyone good at estimating sand use and etc?

the beams are 18ft long. 4 beams each section
we are looking at like 144ft of beam to blast

Chris





this is pic of the other side, no water

Re: Bridge Blasting


Sidebar:

I suggest you give your insurance broker a call and run this job by them before you bid on it. Work on bridges, even just sandblasting on a small bridge, is a restricted class for many insurers. Other insurers may want to surcharge.

Also, as this is a public tender where the owner is a township, they may have specific insurance requirements that your current insurance program does not have. For example, the current trend in public works is to require pollution liability insurance and it is possible this job will require this coverage as there is a creek running under the bridge. If you bid on the job and are awarded it, you will then be bound to buy any extra insurance laid out in the specs.

Your broker may tell you that you are good to go with whatever insurance you already have, but seeing as you mentioned that you haven't done bridge work in the past, I would hate for you to find out after the fact that your bid price did not include any extra insurance costs and now the job is no longer profitable for you.

Re: Bridge Blasting


With that said, you had better make sure that the paint that is present does not contain lead. If so and if you don't have experience then you would price yourself out of the job and the township probably don't have the money to even do the project. One flake of lead paint or a speck of spent abrasive get's on the ground or in that water way then you will wish you have never seen that bridge. Do your homework.

How you going to reach up there?

Maybe a vacuum blast system would be better on this job.

Re: Bridge Blasting


im going to build a platform on the water side, i have some scafolding, i could stand on. i live in the country, in the middle of no where. the bridge is local. The engineers told them to just scrape the paint off and repaint it.

as far as the cleanup, i can have a helper as im blasting cleaning up my mess under me, DNR is my main concern but if i build it right, shouldnt be no issues i wouldnt think.

anyone know how to bid this? i just have general libility

Test for lead.
Charge hourly rate plus any extra materials.

I only give estimates now and blasting is buy the hour

Re: Bridge Blasting


12 years ago don't mean nothing. If it wasn't taken down then it probably does. If you don't know then you always assume it does until proven it don't. You really need to do your homework on this one my friend. If you get caught up with it's not only on your hands but everyone involved. If your inexperienced then your chances for success is slim. Your township needs to hire a coatings consultant to specify the project out as well as to do the proper inspection procedures as well to ensure their money is spent wisely. As far as how to bid the project. Figure the estimated cost for all labor, materials and expenses and then put a little in for profit and you have your pricing. As far as anyone here telling you what to charge per hour or foot. Not gonna happen. Your own your own there. No pricing given on this forum.

If Benny was three hours away and free I would pay him to do a site visit and consult you in the whole process. Your only going to gain the needed exp. you will need in the future and succeed at the job at hand.

Re: Bridge Blasting


This is what we had to do to meet the lead paint regs. Air out was filtered and all used abrasive had to be double bagged. It was very hard to price as everything is twice as complicated as any other blasting job we have done.

It all depends on your angle...Getting help quoting something to sound educated might help get the job..or help disqualify yourself from the job..

Re: Bridge Blasting


I understand, but you can be talking a thousand bucks for proffesional consulting fees. Benny for instance would have six hours in to it just from the round trip before he even gets to talk. It would have to be a six figure job you risking it against.

Re: Bridge Blasting


the township is a poor township. They dont got much $. I live in the boonies. No cops around or any local law enforement for 30+ minutes. Only way to safely do this, i think.. is build a wooden box/plastic around it... seal it good

Re: Bridge Blasting


You do realize that you have just announced this job to the world and your intentions to possibly do this job by using un approved means to prevent possible health exposures as well as environmental exposures. Just because your in the boonies don't mean jack. If you decide to go against the rules then you deserve to get caught and fined. Other contractors have to play by the rules and the ones that think that they can fly under the radar gives the industry a black eye.

Re: Bridge Blasting


im just kicking around ideas on how to even think about doing a job like that. I did not place a bid, have not contacted them about it yet. I myself really dont want to get caught messing around a stream with sand or any abrasives that can get into the water. I am aware of the risk being taken if i decided to do the job. I came here asking for any help/insight into a job like this. Not to be casted out as a bad contractor. Ive heard all your opinions. And recommendations. and ill go from there. If i did decide to do the job, it wouldnt be half assed. Im not gonna pay a fine and etc...

Re: Bridge Blasting


Have you received the township's tender specs yet? The information laid out in the specs will tell you how the township wants the job done. The insurance specs will be in there as well, and that will answer the question regarding the pollution insurance requirements and what amount of liability you will be assuming via contract. There really isn't much point guessing without having the full details. You need to read the specs, and then you can figure out if you are comfortable re submitting a bid.

If you would like some input on the insurance, I would be happy to comment. You don't need to post identifying names or locations if you want to keep this job to yourself. Just cut-and-paste the insurance coverage/limits/terms paragraph(s) and I can give some general guidance.

Re: Bridge Blasting


Thanks for info. All they want is general liability. No specs. Their engineer wanted them to scrape off paint and repaint. There was no specs. All they want is it blasted. Clean enough to repaint. Thats what they want.
