Portland-Milwaukie Light Rail, West Segment
Special Inspection/Materials Testing
TriMet, in partnership with several agencies and
municipalities, including the Oregon Department of
Transportation, Multnomah County, Clackamas County, the
City of Portland, the Portland Development Commission,
the City of Milwaukie and the City of Oregon City, is
currently constructing a 4-segment light rail extension
from Portland State University to downtown Milwaukie.
Segment A includes the creation of two new
stations, and the renovation of a third. The costs
of the Milwaukie Light Rail Extension are estimated to
exceed $1.4 billion, with the west segment accounting
for approximately $69.5 million. This segment will
run from the southern most station on the existing Green
and Yellow MAX lines to the west abutment of the
Willamette River Transit Bridge. Additional
stations will be created at the intersection of SW
Lincoln & 3rd and at SW Moody along the South
Waterfront. NTI is currently providing materials
testing and inspection in support of the contractor’s
quality control program. NTI’s scope of materials
testing and inspection services included in-place
nuclear density testing of structural fills, laboratory
analysis of soils and aggregates, visual welding
inspection of reinforcing cages, inspection and testing
of thousands of cubic yards of reinforced concrete, and
ultrasonic inspection of rail connections. The project
is currently scheduled for completion in 2015.
