Fact Sheet: Construction Zone Noise
January 24, 2012
We all know a heavy construction project such as the Columbus Crossroads project can generate a lot of noise, dust and vibrations. And it doesn’t always happen at convenient times, since portions of this project are pretty much a round-the-clock operation.
Since we’ve had questions about this from you and your neighbors, we wanted to get you some answers.
How will the actual construction affect my neighbors and me?
In order to keep the I-71/670 Interchange project on schedule, crews are working overnights and on weekends to remove old bridges. That’s when traffic is at a minimum on local streets and highways, and most of all it is safer for you and the construction workers.
There is much more to demolish in the next few weeks before reconstruction can begin.
Here are a few examples
You may hear a machine called a hoe-ram crunching away at old concrete as it demolishes old pavement and bridge surfaces. Some of this work occurs at night, but only when we have no other choice.
Pile driving (sinking metal columns for bridge supports) normally happens during daylight hours, so any noise will be heard during those hours. Businesses and residences within up to 400-500 feet away could feel some vibrations, although these vibrations are not damaging.
Mining work on the underground micro-tunnel is also underway and can generate considerable noise. Mining operations will occur approximately half the calendar days between now and mid May. When crews are mining, they will work 22 hours per day. The noise is mostly generated as the mining slurry (a mix of water and materials) is cleaned and separated for either recycling or disposal.
Beginning on or about January 29th, crews will begin demolishing the old I-670 East “flyover” bridge, which will take several days. When construction begins on the new flyover, there will be more heavy equipment and pile driving, which usually means noise, dust and vibration. While Kokosing, the contractor, will do everything it can to minimize noise and dust, some of it can’t be avoided.
How noisy will it be and what can we do about it?
Demolition and pile driving to build new bridge supports can be loud. Depending on weather and wind conditions, noise can carry or seem louder.
Area business and residences are advised to make sure doors and windows are shut to minimize noise exposure. Relocating to interior rooms of the home or keeping curtains closed will reduce audible noise. You might also consider turning on a fan or similar device that creates "white noise" to minimize sounds from outside.
Will there be constant pounding?
There will be times when workers will be welding the pile together to build bridges, performing mechanical checks of equipment and changing operators. During these times, noise from the operation may be notably reduced.
Please also be aware that the vehicle back-up alarms you may hear are required by law to protect the safety of those working in the construction zone. Noise like back up alarms on trucks can be annoying but are safety features that save lives and are required by law to help ensure the safety of the construction workers.
ODOT and Kokosing, the contractor, are working closely with the City of Columbus to be respectful of the people who live and work in the area. That includes coordinating with local churches to make sure construction zone noise and vibrations don’t interfere church services or special events. Some noise and vibration, however, cannot be avoided.
Please be assured that ODOT and Kokosing will continue minimize noise to the extent possible. We will also continue to reach out through our neighborhood visits and you can follow us on both Facebook
