07/25-07/26/15 WEEKEND ASPHALT PAVING FROM PUOHALA ELEMENTARY TO KANEOHE PRE-TREATMENT FACILITY (posted 07/23/15 12:20pm)

Asphalt paving activities will take place this Saturday and Sunday between 7:30am and 4:00pm. The impacted area will be from Puohala Elementary School through the golf course to the Kaneohe Pre-treatment Facility. Hauling of materials will take place on both days. Paving of these areas is necessary to assist with controlling mud and dirt tracking from the construction site.

If you have any questions or concerns, please feel free to contact the Construction Management Team by phone or email.

07/14/15 INCREASE IN CONSTRUCTION TRAFFIC DUE TO LARGE CONCRETE PLACEMENT AT KANEOHE PRE-TREATMENT FACILITY ON 07/14/15 (posted 07/13/15 8:00pm)

There will be an increase in construction traffic on 07/14/15 due to a large concrete placement required for the construction of the Kaneohe tremie slab to seal the bottom of the Kaneohe shaft. This work requires the contractor to continuously place cement concrete until the required elevation is achieved. As a result, approximately 30 or more cement trucks will be traveling to and from the Kaneohe Pre-treatment Facility throughout the day.

Thank you for your patience and understanding.

If you have any questions or concerns, please feel free to contact our project team.

Repairs to the 24-inch force main at the Kailua Regional WWTP are now complete.

 

05/12/15 EMERGENCY FORCE MAIN REPAIR AT KAILUA REGIONAL WWTP (near Aikahi Elementary) (posted 05/12/15 2:00pm)

The contractor is currently conducting emergency repairs to a broken section of a 24-inch force main outside the sound wall area located at the Northeast corner of Kailua Regional WWTP near Aikahi Elementary. Please be advised that this work will generate noise especially during the removal of a concrete encasement around the damaged pipe by chipping. Work is anticipated to continue until 6pm. However, this work could extend into night hours if unforeseen conditions are encountered. An update will be provided when the work is completed.

If you have any questions or concerns, please feel free to contact the Construction Management Team by phone or email.

On behalf of the Construction Management Team, thank you in advance for your patience and understanding.

05/11/15 TBM APPROACHING AIKAHI GARDENS (posted 05/11/15 11:00am)

Currently, the TBM is still within the boundaries of the Kailua Regional WWTP, but as tests are completed the TBM will continue to advance along the alignment towards Aikahi Gardens.  Tunnel boring activities will be performed completely below ground and will not affect traffic. Blasting is not anticipated.

Surface vibration readings are currently being recorded in the area above where the boring activities will be and will continue until the completion of the gravity sewer tunnel. Design engineers do not anticipate vibrations will be felt at the surface. Based on monitoring data collected, the contractor can make real-time adjustments to ensure the City is within the vibration limits shared at previous public meetings to avoid damage to structures, retaining walls, roads, and utilities.

04/30/15 BORING HAS BEGUN AT KAILUA REGIONAL WWTP (posted 04/30/15 4:00pm)

At approximately 4pm, boring operations commenced. The contractor is currently conducting routine tests to ensure all parts and equipment are functioning properly. As a result, the TBM is slowly being advanced within the Kailua Regional WWTP.

 

April 2015 BORING TO BEGIN THIS MONTH AT KAILUA REGIONAL WWTP (posted 04/21/15 5:15pm)

This month the Kaneohe-Kailua Gravity Sewer Tunnel project team launches the tunnel boring machine (TBM) at the Kailua Regional Wastewater Treatment Plant (WWTP). The TBM will bore through approximately three miles of basalt rock linking to the Kaneohe Wastewater Pre-Treatment Facility.

Tunnel boring activities will be performed completely below ground and will not affect traffic. Blasting is not anticipated.

Tunnel preparation has been ongoing since August 2014, including the construction of a 250-foot starter tunnel that begins at the Kailua Regional WWTP. The TBM will be setup, tested, and launched from within the starter tunnel where the machine’s gripper shoes will press against the side walls of the tunnel and then advance forward while the rotating cutterhead breaks the rock into small pieces. These pieces, known as tunnel “muck,” are then lifted from the tunnel floor with buckets mounted on the cutterhead and removed from the tunnel via “muck cars” on a temporary tunnel railroad system.

As a safety measure, surface vibration readings will be recorded above boring activities. Design engineers do not anticipate vibrations will be felt at the surface; this monitoring effort is for peace of mind.

Tunnel boring is expected to last about eight months. For up-to-date progress on the boring, click on FOLLOW THE TBM.

04/15/15 EMERGENCY FORCE MAIN REPAIR AT 1:00AM AT KAILUA REGIONAL WWTP (posted 04/14/15 5:00pm)

At approximately 1:00am tonight, the contractor will begin emergency repairs to a section of the 42-inch force main located at the Kailua Regional WWTP. Work is anticipated to take 2 to 4 hours and should be complete by 5:00am. The emergency work must be completed during low flow at the plant, which occurs in the early morning hours. This work is not anticipated to be noisy. However, since this is emergency force main work, please be advised that some noise may be generated if unforeseen conditions are encountered.

If you have any questions or concerns, please feel free to contact the Construction Management Team by phone or email.

02/06/15 PILE DRIVING AT KAILUA REGIONAL WWTP (posted 02/06/15 3:00pm)

The contractor will be pile driving at the Kailua Regional WWTP. This work is outside of the sound attenuation walls that surround most of the contractor's work area. As a result, you may hear a series of loud banging noises coming from the site for the next two weeks.

01/02/15 HOE-RAMMING AT KAILUA REGIONAL WWTP (posted 01/02/15 1:00pm)

Happy New Year! Hope that 2015 brings everyone good fortune.

Southland has excavated down the Kailua TIPS Shaft to tunnel invert elevation and will begin breaking through the concrete slurry wall on January 2, 2015. Hoe-ramming, an activity similar to jackhammering but with the hammer fitted to an excavator, will be required for this work. Although this work will be at the bottom of the shaft within the sound wall, neighbors can still expect to hear some hammering noise coming from the site during the day from 9:00am to 5:30pm except on Saturday and Sunday per the Community Noise Permit for this project. We expect this to go on for a couple of weeks.

If you have any questions about this update or the project, please feel free to contact the Construction Management Team.

12/08/14 SECOND WORK-SHIFT AT KAILUA REGIONAL WWTP TO BEGIN (posted 12/03/14 2:30pm)

Happy holidays!

Excavation at the Kailua Tunnel Influent Pump Station (TIPS) Shaft is underway. In order to maximize the efficiency of this work, the contractor, Southland / Mole JV (SMJV), will be commencing a second work-shift allowed per the project noise variance approved by the Department of Health. The noise variance allows work within the sound wall in the shaft 24 hours/day, except Sundays. The second shift SMJV is planning to work will be from 5:00pm to 3:00am, Monday thru Friday and Saturday from 5:00pm until Sunday morning at 12:00am (see schedule below) starting Monday, December 8, 2014.

Work during this additional shift will occur only within the Kailua TIPS shaft which SMJV has recently excavated down 45 feet below grade. Work during these hours will include starter tunnel work (will stay within the wastewater treatment plant property), hoisting of tunnel muck (wet dirt or mud) and installation/maintenance of supporting utilities within the shaft. These tasks will occur underground and/or within the project sound wall. Controlled blasts are not anticipated for this work. If deemed necessary the Construction Management Team will distribute announcement notices and will monitor noise and vibration effects very closely.

The tunnel construction (beyond the wastewater treatment plant property) will not begin until 1st quarter 2015. The Construction Management Team will distribute an announcement prior to tunnel construction.

Additionally, there will be no construction truck traffic after 9:00pm until 8:30am. Approved construction truck traffic hours will be between 8:30am and 9:00pm (but not between 4:00-5:30pm M-F) daily at the Kailua Regional Wastewater Treatment Plant. Please note the truck operators are required to follow a specific hauling route that avoids the Aikahi area and Kaneohe Bay Drive on the Kaneohe side of Paku Place.

New Work Hours at the Kailua Regional Wastewater Treatment Plant (WWTP)
Monday: 7:00am-3:00am (Tuesday morning)
Tuesday: 7:00am-3:00am (Wednesday morning)
