The Willamette River Bridge Project will replace the existing bridge on Interstate 5 (I-5) over the Willamette River at Eugene and replace a second structure over a canoe canal. The replacement bridge will be two parallel concrete deck arch structures with two piers in the main channel of the river. The proposed structures are 1,759 feet long (SB) and 1,985 feet long (NB.) The bridges are composed of three structure types: a cast-in-place concrete girder span, two concrete deck arch spans over the Willamette River, and several spans of precast concrete tub girders over Franklin Boulevard, UPRR, and the NB exit ramp from I-5 to Franklin Boulevard. The bridge foundation will utilize 8-foot diameter drilled shafts.
The project is the largest CMGC transportation project in the State of Oregon and consists of the following components: demolition of the existing Willamette River Bridge, construction of the replacement bridges, reconstruction of the roadway approaches plus retaining walls, sound walls and major improvements to a park area and pedestrian path under and adjacent to the bridge. Work is being funded under the Oregon Transportation Investment Act, a $2.5 billion program to upgrade bridges on major transportation corridors throughout the State of Oregon.
CZE has the lead responsibility to manage the design quality control program, prepare the Project Quality Plan and directs the design review process for the entire Willamette River Bridge design team which is being led by OBEC Engineers and TY Lin International. QC activities require extensive interaction with the Oregon DOT, its project management consultant, the design team, and the CMGC team led by Hamilton Construction.

$1.4 billion |
|
The new $1.4 billion, 7.3 mile section will have 10 stations and 2,000 park & ride spaces and have a ridership estimated at 27,400 daily trips by 2030. The alignment will include a new cable stay, transit only bridge over the Willamette River. Cooper Zietz is providing design QA/QC for the west bank alignment preliminary design work led by CH2M Hill and design quality audits of the east bank alignment preliminary design work led by Hatch Mott MacDonald.

Project Title:
Columbia River Crossing Environmental
Impact Statement
Location:
Vancouver, Washington
Client: David Evans and Associates
|
|
CZE served as the
Project Quality Manager/Quality Team for this $50M project
investigating the replacement of the I-5 bridges across the
Columbia River between Oregon and Washington. Options being
considered include a new 3-lane bidirectional bridge with
light rail and modifications to 8 major interchanges. In addition
to completing the EIS, the project involves the preparation
of 30% preliminary design plans, specifications, and estimates.
CZE is responsible for preparing the Quality Plan and implementing
procedures, conducting audits of ongoing activities, and conducting
document review and design reviews. |

| Provided design and construction
engineering services for the construction of 18 boat ramps
and campsite areas for Indian Tribes with treaty fishing rights.
The improvements, with a construction cost of $30 million,
included breakwaters, floating wave attenuators, transient
docks, access roadway improvements, utilities, restroom and
shower buildings, fish cleaning stations, group shelters,
landscaping and other site amenities. The firm was involved
in environmental agency reviews and making applications for
construction permits. |

| Planning,
design, preparation of Contract Documents, construction management,
field inspection and building commissioning for a 105,000
sf hospital and outpatient medical and dental facility, visitor
and employee parking, ambulance bay, sitework and off-site
utilities located on the Rosebud Sioux Indian Reservation.
Responsible for monitoring all construction trades, coordination
with the prime contractor, payment and change order approvals
and final project acceptance. Total construction cost was
$13 million. |

Bureau
of Indian Affairs, US Department of the Interior
|
|
| Provided full project
design and construction management services for the expansion
of a salmon hatchery located on Annette Island in SE Alaska.
Work included new rearing ponds, marine outfall, new water
supply, access road improvements and a laboratory building
addition. |
|
|
|
| CZE designed a new water
distribution system, sanitary sewers, electrical distribution
system, streets, parking areas, access road and entry, residential
housing and structural improvements and renovations to the
tribal longhouse including a new community kitchen. Other
site improvements included a restroom/shower building for
large group gatherings, RV parking, landscaping, and fish
cleaning facility. |

|
|
| Design and construction
management services for to rehabilitate two irrigation and
flood control dams on the Pine Ridge Indian Reservation. The
$6.1 million project, funded by the dam safety program of
the US Department of the Interior, involved spillway modification,
rip rap placement, improvements to gates, raising of earthworks
and other repairs. |

Netarts-Oceanside
Sanitary District. |
|
| Provided design and construction
management services to the Netarts-Oceanside Sanitary District
for the installation of a new ocean outfall sewer. The sewer
was constructed under difficult conditions and crossed a sand
beach and extended some 3000 feet beyond the surf zone to
a depth of minus 10 meters. A plume dispersion analysis led
to the design of the diffuser section that would assure good
mixing. The outfall pipe and anchor-age system was designed
for installation during one tidal cycle and had to withstand
100-mph storms. The project was funded by an EPA grant. |
|
|
|
| Design and construction
management services for various phases and components of a
new $125 million regional sewerage system for the Eugene-Springfield
area. Specific projects included a major pumping station,
a land application facility for irrigation of food processing
wastes, 35 acres of sludge drying beds, construction of a
new regional wastewater treatment plant and major sewer interceptors.
The new treatment facility included a new headworks with automated
trash racks, grit removal and prechlorination.. Project was
funded under a grant from US EPA. |
|
|
|
| Provided design services
for a $15 million renovation and new construction of 18 sewage
pumping stations ranging from small duplex submersible stations
to large 30-foot diameter by 40-foot deep stations with 4
to 6 pumps. The project also included mechanical and electrical
site inspections for 13 pumping stations to determine the
degree of mechanical deficiencies, condition of pumps, motors,
valves, water seal units, sump pumps, ventilation systems,
and level controls. Electrical system inspections were also
made. Work included rehabilitating stations to bring them
up to current safety codes, standards and improved mechanical
reliability. |

| The Kafrein Dam is one
of several dams constructed along the East Wadis serving irrigation
systems in the Jordan Valley. Previous studies determined
that the existing earth fill dam could be raised some 21 meters.

determine the feasibility of raising the Kafrein Dam; evaluate
seepage and sedimentation effects on reservoir yield and irrigation
system operation; review and update the economic analysis
for the project; and advise the Jordan Valley Water Authority
and USAID on the appropriateness of the findings and recommendations.
