Overview

 

This is an update on the status of the US 20:  Pioneer Mountain to Eddyville project; the status of the dispute between ODOT and the Design Builder, Yaquina River Constructors; and a look at what direction the project may take from here.

 

Remaining site work on the US 20:  Pioneer Mountain to Eddyville project is stopped and remains on hold due to continuing landslide activity at four bridge locations where landslide mitigation work, which was added to the contract in 2008, has failed.  The four bridge locations are in the center of the project; these are (east to west) Eddy ‘C’, Eddy ‘B’, Crystal Creek, and Cougar Creek. 

 

The Design Builder and ODOT are in dispute over responsibility for the cost of the additional engineering and construction, and the delay to the project associated with the failed landslide mitigation.

 

Procurement / Delivery Method:

 

ODOT determined that this project should be delivered as a Design-Build project, an approach where the contractor provides both the engineer to design the project as well as the construction contractor to build the project. 

 

The Design Build contract was awarded to Yaquina River Constructors (Granite Construction).

  

New Developments

 

  • The Design Builder is proposing design concepts at the four locations where the landslide mitigation has failed that move toward fewer or no bridges built at the four landslide locations.   
  •  
  • ODOT ‘s goal is to find solutions and resume construction in 2012

 

  • The Dispute Review Board has issued a recommendation in the dispute between the Design Builder and ODOT.    

 

  • Updated information has been developed on the status of four bridge locations.

  

Bridge Location Update

 

In February, 2010, the Design Builder notified ODOT that bridge columns at the Eddy B and Cougar Creek locations had moved out of plumb.

 

Additional monitoring by the Design Builder found ground movement in the landslide areas of all four bridge locations:   Eddy C, Eddy B, Crystal Creek, and Cougar Creek. 

 

 

These four locations were the focus of significant landslide mitigation work added to the contract in 2008, including the construction of large buttresses and shear keys at the bottom of the slopes to hold the four slides in place.   The mitigation has failed.

 

 

Current Status

 

    Eddy C

The Design Builder has determined that the $7.4 million completed bridge at this location has been compromised by continued landslide activity.  Its future remains undetermined.  Action has been taken to relieve stress caused by the landslide movement on the bridge foundations.

 

 

Eddy B

In March of 2010, the Design Builder demolished the bridge columns that had moved out of plumb.  Piles were driven around the drilled shafts and a foundation was constructed in anticipation of erecting new columns. No work has taken place at this location since then.

 

Crystal Creek

While ground movement has been monitored at Crystal Creek, there has been no movement recorded in any of the 5 sets of columns or two end bents.  No work has taken place at this location since February 2010.

 

  

Cougar Creek

The Design Builder recommends the removal of Cougar Bridge Bent 4 that was found to be out of plumb in February, 2010.  No action to remove the bent has yet been taken. No other work has taken place at this location since the discovery of out of plumb columns in February 2010.

 

 

Completing the Project

 

ODOT, along with the Design Builder, continues to monitor and assess landslide activity within the project boundaries.

 

In October, 2011, the Design Builder informed ODOT that their engineers do not support pursuing the construction of bridges at the four locations where landslide activity continues. 

 

Eliminating the four bridges would require significant changes in alignment and profile to enable the roadway construction through the four creek drainages rather than traveling on bridges above the drainages.

 

ODOT is encouraging the Design Builder to provide more details on this concept so that discussions can begin with the environmental agencies to learn how this impacts our permits.

 

ODOT’s goal is for solutions to be determined and on-site work to be resumed in the 2012 work season.

  

  

Design Builder/ODOT Dispute

 

The Design Builder and ODOT are in dispute over responsibility for the cost of the additional engineering and construction, and the delay to the project associated with the failed landslide mitigation.   

 

ODOT’s belief is that this is a design-build contract and the Design Builder is responsible for the design.  The Design Builder performed the engineering and design, and the Design Builder constructed the mitigation work.  The Design Builder remains responsible for the successful completion of the project.

 

The Contract allows a dispute to be presented to a Dispute Review Board (DRB) for a non-binding recommendation of resolution prior to the Design Builder pursuing a claim.  The Contract states that if either Party does not accept the DRB’s recommendation, the Design Builder may pursue a claim according to the terms of the contract.

 

 

The landslide mitigation failure issue was presented to the DRB in July of 2011.  The Dispute Review Board has issued a non-binding recommendation in the dispute between the Design Builder and ODOT. ODOT has chosen not to accept the recommendation.  The Design Builder now has the right to pursue a claim under the terms of the contract.

 

Overall Project Status

 

The new roadway is paved from the easterly end of the project into the Eddy ‘C’ Bridge, and from the westerly end of the new alignment into the Cougar Creek location. 

 

Project bridges that are completed and unaffected by the landslide activity are: Little Elk Creek Bridge, Trapp Creek Bridge, Yaquina River Bridge, Western Pacific Railroad Bridge, Elk City Road Bridge, Simpson Creek Bridge, and Hayes Creek Bridge.

 

The project is essentially complete except for the middle segment containing the four bridges.

 

ODOT anticipates two construction seasons of work will be necessary to complete the project, once the final solution is designed.

 

 

Project Budget

 

The original construction allocation was $140,185,000

 

Since then, there have been four additional allocations approved by the Oregon Transportation Commission

:

  • 9/10/08 for $64,995,101
  • 2/27/09 for $4,800,527
  • 1/14/10 for $5,300,000
  • 9/8/10 for $1,744,238

 

The current TOTAL construction allocation (Original and subsequent allocations) is $217,024,866.

 

The current construction expenditures total $194,647,146.

That leaves $22,377,720 remaining for construction.

 

In addition, there have been the following expenditures:

  • Preliminary Engineering-$7,353,034
  • Right of Way-$5,928,184
  • Utilities-$197,422

 

The total expenditures for the project currently stand at $208,125,786

June, 2011 Update

Posted 7 months ago

Overview and update

Although bridge construction on the project has been delayed since February, 2010, the project continues to move forward and work is planned for the 2011 construction season.

 

In February 2010, movement was detected at two bridge locations, and subsequently at two additional bridge locations.  Since then, ODOT and the Design Builder have been in dispute about responsibility for the correction of the mitigation at these four sites.  

 

ODOT is actively engaging the Design Builder on the best way to finish the project.  The terms of the contract make the Design Builder responsible for the design and construction of the project.  It is the Design Builder’s responsibility to provide the design for the project.  The Design Builder must provide the analysis of the problem and subsequent corrective actions.  As the owner, ODOT’s role is to review the Design Builder’s information, using third parties for input, if necessary.

 

The contract completion date of December, 2011 can not be met.  Limited bridge construction and earth work will take place during the current construction season.  We have not ruled out a 2012 completion date.  Due to many factors, a 2013 completion date is also a possibility.

 

ODOT is mindful of the significance of this project on this important corridor and the investment that has already been made.  ODOT is committed to completing the project and opening the new highway as quickly as is feasible while being good stewards of the taxpayers’ investment in this facility.

 

ODOT will not compromise long-term safety.  The earth movement needs to be understood and resolved before the bridges can be completed.  We continue to monitor movement at several project locations.  Data collection is continuing.  We are developing important trend lines for the settlement and movement occurring at the project site.  We will continue to monitor and add data as the season moves through spring and into summer.

 

Due to the geology and the rain in the Coast Range and the subsequent saturation of the soils, earthwork on this project can only happen during the summer months.

During the winter shutdown, we continued to work with the Design Builder on erosion control and other typical site maintenance requirements.  The project is doing well with erosion control.  We enjoy a strong working relationship with environmental regulators who have recognized this project’s erosion control, after the 2007 summer re-work, as a success.

 

 

 

Other US 20 project “on schedule”

The U.S. 20: Pioneer Mountain Loop Road-Yaquina River project, immediately west of Pioneer Mountain-Eddyville, continues on schedule.  We appear on track for the summer 2011 finish of the approximately $7 million project.

Bridge bent and ground movement update

Posted about 1 year ago

As we first reported in March, 2010 and updated in June and November, we have been monitoring for ground movement at several bridge locations within the project boundary after two bridge columns were found to have moved out-of-plumb.

 

In December, we were notified by our contractor that additional movement was detected in the area of the Eddy C Bridge.  Additional movement has also been detected in other landslide areas of the project.

 

We are now working to independently verify how much movement there has been and what the significance of the movement is. 

 

We have installed additional instruments to monitor the landslide areas.

 

We hope to have enough data by early spring so the contractor  can make a decision on how to respond to the movement.  At that time, we hope to have a better estimate on when bridge construction can restart, how much it will cost and when we might complete the project.

 

When construction begins again, we will have about one season of work left to complete the project.  Some of that work includes:

  • 100,000 cubic yards of material to be excavated
  • 4 bridges to complete
  • Paving the remaining 50 percent of new alignment (About half of it was paved in 2010)
  • Planting vegetation in the disturbed soil areas

Second U.S. 20 project “on schedule”

Posted about 1 year ago

 

 

We also made good progress on the second project that will make U.S. 20 safer and more efficient for motorists. 

·     About 80,000 cubic yards of rock and soil have been removed for the new alignment over Simpson Creek; this sets the stage to build the new bridge during this winter.

·     A critical soil retaining wall has been completed, improving site distance through this curvy part of U.S. 20.

·     All storm water culverts have been installed.

·     Only bridge and concrete work will take place during the winter.

·     The U.S. 20: Pioneer Mountain Loop Road-Yaquina River project, immediately west of Pioneer Mountain-Eddyville, continues on schedule.  We appear on track for the summer 2011 finish.

 

The $8.5 million project will realign the curves near Sam’s Creek Road to allow interstate-size trucks to use this section of highway.  The highway will be shifted north for environmental protection of the creek and will construct a new, fish-friendly bridge over Simpson Creek, replacing a restrictive culvert.  The road will also receive a pavement overlay throughout this section.
