Vacuum Sweeper Maintenance

If I specify a vacuum sweeper on a construction project, I expect it to be operational.

I require all systems to be functional per manufacturers specifications.

If not, the sweeper goes away, maybe the job is shut down, until a working sweeper is brought to the site.

Specifications:
1) Power brooms shall not be utilized without prior approval by
the Engineer.

2) Contractor shall have sufficient working vacuum sweepers on
site at all times work is being performed.

3) All sweepers shall have on-board water spray systems that
shall be operating at all times.

4) systems shall function per manufacturer specifications
including, but not limited to, spray water systems, blowers,
vacuum nozzles, hoses, debris hopper, hydraulics and
electrical.

5) At no time shall debris hopper seals leak debris and liquids.

Why Power Brooms are a Bad Idea

Filed under: Video — Tags: , , , , , , — Sheetflow @ 10:13 am

As you can see, these types of sweepers don’t pick up dirt and sediment from asphalt, they just spread it around.

Water spray system attachments help some but then the sweeper mostly turns the dirt to mud and smears it around.

These are useful for picking up gravel and sand.

A vacuum sweeper is the way to go.

Soil Stockpile Needs to be on Plastic

Filed under: Video — Sheetflow @ 7:10 am

Soil stockpiled on asphalt will leave soil residue no matter how much you sweep. When possible, stockpile soil on heavy plastic, plywood, geotextile fabric, or some other material.

Clean Water Diversion Using an Unrolled Asphalt Road Edge

Filed under: Video — Sheetflow @ 7:00 am

My favorite best management practices are the ones that involve a slight modification of the contractor’s “means and methods“. On this project, the foreman told the roller operator not to go all the way to the edge of the new asphalt, leaving a small, rolled asphalt edge. Since this is the first lift of asphalt, with several more inches to be added later, this will be covered up near the end of the project. At that time, stormwater will run off the asphalt shoulder into a grass-lined ditch. The best part is this was done at no additional cost to the owner.
