Construction Updates

Construction Activity- Week of May 11, 2015

Lincoln Wastewater Reclamation and Treatment Facility Construction Activity

            

Work/Activities Performed Last Week:
-Mason Painting working on above pump deck pump header piping for four days last week, missing only Thursday due to rain.
-The last of the pipe supports were completed along with grouting under the pig launch assembly and around the through the deck pump discharge pipes.
-DCI – Poured the concrete landings at the electrical building and the perimeter walk around the standby generator slab. Still two sidewalk sections remaining between north landing and generator walk, and down the west side of the electrical building.
– DCI – Not much done on installing 3‐way valves for hose bibbs as DCI and HD Supply could not find the specified valve and have submitted an alternate product.
-DCI – Some AB material brought in for final grading however DCI will submit an alternate recycled base rock for AB surface areas to provide a surface that will not ravel as much as the approved AB that is a more rounded river rock.
– CraneWorks – Testing of the overhead monorail crane mechanism by the factory representative to certify the crane and conducted the lift tests and training on May 5th.
-DCI – Continued to clean up the lay down area north of the generators.
-DCI ‐ Continued to monitor SWPPP measures and review the SWPPP approach & BMP’s with some cleanup before the Thursday rain event.
-DCI – the 72” junction manhole was tested this week, but still have a leak which may be at the pipe to concrete manhole base connection.
– DCI – The supports for the ARV vent lines still need to be installed at the deck piping.
Work/Activities Planned for this week:
-DCI – Install angle iron for grating supports at the HWDS to allow Mason Painting to start on the inside 100% solids coating of the inside surface.
-DCI – Pour the two remaining concrete sidewalks at the electrical building.
– DCI – Continue to install water lines and 3‐way valves for hose bibbs around pump station area.
-DCI – Have AB material brought in for final grading of AB areas and prepare subgrade for final paving at east entrance road and between pump station and electric Bldg.
-DCI – Will continue to clean up the lay down area north of the generators and possibly start rough grading per Stantec’s revised grading plan and at DCI’s laydown area.
-DCI ‐ Continue to monitor SWPPP measures and review the SWPPP approach & BMP’s.

 


Pipeline Construction Activity

Construction Activity Notification

Wise Road

The horizontal directionally drilling (HDD) installation beneath Doty Ravine is underway.  As a result, there may be an increase in construction traffic on and around Wise Road.

Highway 193 (Off Pavement)

Excavation off-pavement from Highway 193 for the installation of the pigging station is underway. There will be trucks entering and exiting the site, which will have a minimal impact on traffic. No lane closures are anticipated for this work.

Virginiatown Road

The horizontal directionally drilling (HDD) installation beneath Auburn Ravine is underway. There may be an increase in construction traffic on and around Virginiatown Road west of Fowler Road.

Chili Hill Road

Culvert repairs will continue the week of May 18. Traffic impacts during this time will be minimal.

Lincoln Blvd./Old Highway 65 (Off Pavement)

Installation of the biofilter will resume the week of May 18 on the parcel northeast of the intersection of Lincoln Blvd. and Ferrrari Ranch Road in Lincoln.  This work involves new piping, fans, and electrical improvements. There will be trucks entering and exiting the site, which will have a minimal impact on traffic.

Mt. Vernon and Joeger Road Update

This week, the contractor is completing the pipeline installation at the intersection of Joeger Road and Bell Road. Starting the week of May 18, the location of the work will move to Joeger Road near SMD-1 (near Meadow Glen Road). Work will progress toward the west, and then southwesterly, towards Dry Creek Road. Please utilize the detour where possible. Additional details on remaining work next week will follow in a separate email notification.

In order to expedite completion of the construction activity, the contractor is implementing overnight flagged traffic controls for the pipeline construction in Joeger Road. This allows the contractor to complete the construction on Joeger Road more quickly, because the construction equipment will not be required to move on and off site every day.  This overnight traffic control is expected to last until July 2015, and it will only be in effect during the week. The road will return to two lane traffic on weekends and holidays.

PLEASE NOTE- CONSTRUCTION WORK WILL NOT BE 24 HOURS A DAY.  Active construction will take place between 7:00 a.m. to 7 p.m. Monday through Friday, and 9:00 a.m. and 6 p.m. Saturdays, as approved by and coordinated with the City of Lincoln inspector.

The overnight single lane closure will be limited to 300 feet (much less than the closures you have seen during the working periods).There will be a flagger present at both ends of the construction zone 24 hours a day.  A third flagger will be on site to help direct traffic as necessary. Light plants and flashing signs/traffic cones will be in place in order to ensure visibility for the flaggers and safety for motorists in this zone.  The light plants will be directed in such a way to avoid disrupting homes in the area and to avoid creating a disabling glare for motorists.

Access to Joeger Road will occur as follows:

  • 7 a.m. – 9 a.m.: (FLAGGED TRAFFIC). One-way traffic control through the work zone on Joeger Road (except Saturdays and Sundays)
  • 9 a.m. – 3 p.m.: Total closure Joeger Road within the work zone, excluding Emergency vehicles, school buses, and residents accessing their property (except Sundays)
  • 3 p.m. to 7.p.m. (FLAGGED TRAFFIC). One-way traffic control through the work zone on Joeger Road (Fridays)
  • 3 p.m. to 6.p.m. (FLAGGED TRAFFIC). One-way traffic control through the work zone on Joeger Road (some Saturdays)
  • 3 p.m. to 7.a.m. (OVER NIGHT FLAGGED TRAFFIC). One-way traffic control through the work zone on Joeger Road (Monday through Thursday only)

During one-way traffic control, drivers may be required to stop for 15-20 minutes at the direction of a flagger. Please utilize the detour, where possible, to avoid the work zone.

Please note- ALL pedestrians and cyclists MUST be escorted through the construction zone by a member of the construction crew during active construction periods.

We apologize for the inconvenience.

Post-construction Roadway Pavement Process

In the construction segments where the pipeline is being installed in a roadway the existing pavement is excavated for pipeline placement.  After the pipeline is installed and the trench filled in, a temporary pavement patch is placed on the disturbed section of roadway.  After the pipeline has been installed, a variety of pipeline-related equipment such as air release or blow off valves are placed along the alignment.  Once that work is completed and no further construction activity is required, the contractor will provide the permanent paving patch over the disturbed section of roadway.  This will likely occur later this fall, depending on construction circumstances.  We appreciate your cooperation and patience!
