When you retain GeoInsight, we integrate ourselves with your existing project team to understand project objectives, restrictions, and variables and to ensure seamless communication. This helps us design and evaluate an efficient, technically-sound, cost-effective investigation approach that makes sense for your project and meets the design team's goals.
Investigation objectives are often defined by site conditions, proposed or existing structural loads, environmental loads (e.g., wind and hydrostatic forces), the configuration of the structure (i.e., a tower versus a heavy machine), and the area of influence of the proposed or existing structure. Our depth of experience with New England geology gives us strong intuition about where and what types of geotechnical soil samples to collect for field and laboratory tests to support investigation activities.
Clients frequently request the preparation or review of project specifications and construction drawings following our geotechnical evaluation. This involvement ensures that our investigation and evaluation results are accurately transferred to the final design and construction, achieving a deeper level of quality assurance.
We have experience in foundation studies for buildings, utilities, pipe jacking operations, towers, signs, tanks, machines, bridges, and roadways. When necessary, we rely on our relationships with numerous foundation contractors to obtain site-specific cost or construction input information for our design recommendations.
GeoInsight commonly aids in the selection and design of foundations comprised of timber piles, precast concrete piles, steel beam and pipe piles, pressure injected footings, caissons, and pressure-grouted or cast-in-place piles. For deep foundation system investigations, soil borings are normally required, and the program must be carefully planned. Foundation selection depends on soil strength, bearing depth, and load support required to evaluate soils at the design depth.
We provide oversight during installation of deep foundation elements (e.g., piles, caissons, pressure injected footings, etc.). We monitor installations, evaluate data, and prepare installation or load tests for these foundation elements. We also assess the integrity of installed foundation units (such as using a non-destructive concrete pile continuity instrument). Furthermore, we can also identify when instrumentation is needed to provide information on in situ conditions, and what type should be installed as well as vibration and settlement instrumentation.
Shallow investigation can often be accomplished using a combination of techniques, such as soil borings, test pit excavations, and geophysics.
We are familiar with multiple investigation techniques and have conducted explorations at sites with widely-varying above- and below-ground conditions. We offer you the methods best suited to your project’s technical requirements and cost framework.
Geotechnical exploration may be required at locations with complex and variable geology, including:
GeoInsight staff members have prepared reports and work plans for hundreds of projects, aiding development and construction planning and evaluation. Our reports are tailored to the project requirements and can range from simple data transmittals to complex multi-volume documents.
We also frequently prepare or review project specifications and construction drawings following our geotechnical evaluation. This involvement ensures accurate transfer of investigation and geotechnical evaluation results to the final design and construction, providing you an added level of quality assurance.
