HIGHWAYS
AND BRIDGES
Major current or recent transportation projects involving
SGSI personnel are briefly listed below:
|
Burro Creek Bridge |
|
Geotechnical exploration, geotechnical
engineering, and design services for resloping and rock fall
mitigation along SR 366 in Graham County, AZ. SGSI is handling
all the drilling, field geology, and rock excavation matters
on this current design project.
|
|
|
Rock excavation planning, specifications,
blasting surveillance, blasting vibration measurement and
control plans, blast plan review, and field engineering for
the new Navajo Bridge in Arizona (pictured at right).
|
Navajo Bridge, AZ |
|
Geotechnical exploration, geotechnical
engineering, and design services for the reconstruction of
US 60 at Hagen Hill in Gila County, AZ. The project entails
intricate and extensive excavation of tall, narrow cuts in
basalt. SGSI had responsibility for all the rock slope exploration,
field geology, and rock excavation matters on this project.
|
|
|
Geological engineering and
blasting consulting for the construction of Segment E on Arizona
SR 87 between Mesa and Payson. This is a direct outgrowth
of Mr. Cummings' instrumental involvement in the geotechnical
exploration, design and construction of Segments A through
E of that highway. Extensive coordination with the Tonto National
Forest was involved, as well as specialized rock excavation
and slope treatment techniques under very strong visual attainment
and traffic control constraints.
|
|
|
Foundation exploration,
design, and rock excavation plans, specifications, and estimates
(PS&E) for a new steel arch bridge on State Route 9 over
the Virgin River gorge, Hurricane, UT.
|
|
|
Blasting Consultant during
the design, and the construction, of the Lava Rock and Kaiser
Spring segments of US 93 in Mohave County, with responsibility
for rock blasting, rock sculpting, slope finishing, and related
constructibility assessments. This has entailed extensive
coordination with the Bureau of Land Management, as well as
review and administration of rock excavation practices to
meet the dual goals of stability and appearance.
|
|
|
Geological engineering for
rock excavation and slope treatment of US 89A between Sedona
and Dry Creek. This entails close coordination with the Coconino
National Forest to meet stringent aesthetic criteria without
sacrificing constructibility or slope stability.
|
|
|
Probabilistic slope design
calculations for proposed relocation of US-191 through Phelps
Dodge's new Coronado Pit, part of the large Morenci Mine complex
near Clifton, AZ.
|
|
|
Rock excavation and stabilization
tradeoff studies, rock bolting design, field engineering and
inspection, and reporting for Lower Sabino Canyon, AZ. SGSI's
design and implementation of a rock bolt pattern prevented
collapse of a 70-ft-tall rock outcrop above a heavily-used
road at this popular tourist destination.
|
|
|
Drilled shaft exploration
and design for 5 new I-10 bridges and retaining walls near
Tucson, AZ.
