MACTEC geotechnical engineers and earth scientists
are established specialists in soils engineering,
hydrology, geology, geophysics, seismology, and
rock mechanics. Through our state-of-the-art exploratory
techniques, we determine the behavior of soil,
water and rock as they are affected by natural
phenomena and construction activities.
Geotechnical services begin with project planning
and design, and extend into the construction phase.
MACTEC’s geotechnical activities encompass
soil, water and rock exploration and sampling,
as well as laboratory testing of soil and rock.
To determine the most appropriate subgrade preparation,
pavement design, or foundation type for a variety
of structures, MACTEC geotechnical consultants
investigate the soils and foundation conditions
at potential project sites. As a direct result
of our longevity in the industry, MACTEC is extremely
familiar with site and subsurface conditions that
may adversely affect foundation installation and
general construction. Our engineers and technicians
provide substantiated data for the most appropriate
design for the site conditions, including consideration
of alternative designs and their impact on cost.
In addition, MACTEC’s familiarity with soil
and site conditions throughout the US and abroad
contributes to early planning activities, avoiding
potential difficulties, wasted time, and the resulting
increased cost.
Value Added Recommendations
MACTEC geotechnical engineers are experienced
in evaluating and providing geotechnical recommendations
for virtually every construction situation, including
the performance of various shallow and deep foundations,
slopes, earth embankments, retaining walls, dams,
bridges, and pavement sections under both light
and heavy traffic loading.
Construction Quality
Assurance Laboratory Testing
Using nationally certified laboratories, MACTEC
provides in-house, supplementary testing services
in conjunction with subsurface investigations
and quality assurance programs, including laboratory
testing and construction materials testing.
Other geotechnical services include:
• Construction Monitoring Programs, including
erosion and sediment control plans
• Blasting Engineering Characteristics
• Earthquake Engineering Characteristics
• Embankments, including seepage and slope stability
analysis, and slope erosion control
• Excavations, including shafts, tunnels and bracings
• Foundation Engineering, including piles, drilled
shafts, and bearing and settlement analysis
• Karst Terrain
• Subgrade and Pavements, including geotextile
fabrics stabilization, ground surface subsidence,
and grouting application
