Hey guys the township i live in is taking bids to ad on to our youth sports complex. They are adding another soccer field. Now im not bidding on this job but i got the specs on it and im going to see what kind of number is can come up with to see if im near what the winning bid is. However they said they have about 25 guys that are bidding on in!!! so Im sure there will be some low bids in there.

Heres the main part of the ad i saw in the paper for it:

BASE BID~ Construction of one North American Soccer League standard size soccer field at the northeast end of Evans Park located in Allegheny County, PA. The major tasks of work include clearing and grubbing 7.6 acres, establishing. Erosion and Sedimentation Control and Stormwater Management Control BMPs in accordance with the NPDES Permit #E02-1594. Bulk earth moving of approximately 25,000 cy., 352 ft. of 15" RCCP underdrain, approximately 1,000 ft. of PVC piping of various sizes, 4,114 sy. of Surface Treatment for the access road and parking lot, a permanent wet retention basin and appurtenances.

ADDITIVE ALTERNATE BID: Construction of an off-site stream and wetland Mitigation Area located on lands of Waste Management Landfill along Piney Fork Creek approximately 1.75 miles from Evans Park.

Restoration will be in accordance with the approved mitigation plan. Compliance with the approved Erosion and Sedimentation Control plan, planting and maintenance of the site are also included.

Theres a lot of specs in the plans but il give a few.
Most of the field it self is going to be all fill. So that 30,000 cy is going to be the fill.
352 ft 15'' RCCP non-sealed joint
206 ft 15" CPP smooth Bore
3 precast manhole bases, cone tops
58 vf Precast barrel sections
270 tons of #57 agg. for that.

380 ft 12" Perf. PVC
760 tons #57 agg.

Sediment Basin Construction
Clear 1 acre
5700 cy excavation

Clearing of rest of site. 5.5 acres
Remove topsoil/stockpile. 2500 cy

Bulk earth work. 30,000 cy

487 tons #57 agg.

Parking lot construction
1000 cy excavation

Those are just some of the main points from the bid sheet im looking at. Iv never even looked at something like this before.

I really dont even know what size machines would be needed for the job.

Im going to do some research on this and see what i can come up with. If you guys have any tips or helpful advice to pass on id appreciate it.

Thanks

I can give some advice on the equipment for now. I'll do a little number crunching and get back after that.

For the fill, depending on how much manpower you have and how many trucks you want to run, all you need is a D6 and a decent sized roller. We've done 150,000 tons with a D6RLGP and roller, been working on it for 7 weeks. Typically a D6 can keep up with around 400tons per hour, we could probably do a little more but that's what we've been working with for trucks.

For the pipe, a 20-25 ton hoe will be fine. For support, a 12-15 ton hoe with hoepac and 3.5 yard loader to run pipe and bedding material.

For your builk cuts, this really depends again on the amount of trucks you want to run and your manpower. You could run anywhere from a 30-60 ton hoe, it's up to you. Without seeing the site and how the cuts are laid out, it's tough to know what would be better, a truck and hoe show or scrapers. For truck show, at least (2) 40 ton ADTs will be fine, depending on haul times. If you're running a 6 in the fill, trying to stay around 400 tons per hour would be ideal and that depends on the ability to compact the material more than getting it spread. I can keep up with a D6 on my roller very easily, even considering the fact that the material I've been in is a pain in the ass to compact. Moisture content and other variations will play into the compaction game, but it's easy to change the compaction requirements if you need to.

I can't offer too much info about scrapers, best guess is maybe 2-3 631's as that's all I'm really familiar with out here. Same fill site requirements but you'd need a push cat in the cut. You'd more than likely get the same production, depending on soil conditions, with (2) 631's as (2) 40 ton ADTs, payload is about the same. Scrapers load faster though, however you have added cost of having a push cat which will need to be an 8 at the very least.

Thanks for your input.

I was pretty much thinking the same as you are with the equipment, I wasnt sure on what size dozer though.

I was readind over the specs and it says for the land clearing, they want all trees over 6" in diamater to be cut into no longer then 16' sections and transported to the township stoarage lot which is actually on site but on the other side of the park. This is a whole baseball and soccer complex. Theres about 9 baseball fields and 2 soccer fields now.

Also this is a prevaling wage job.
