Earth.jpg (27988 bytes)A pillar of HSA’s practice is our expertise in the geosciences. You benefit from our multidisciplinary capabilities in such fields as geotechnical engineering, geology, hydrology, hydrogeology and geophysics. These diversified skills in the geosciences blend with the company’s broad-based engineering and environmental experience allowing us to offer you a wide variety of geotechnical services, along with related expertise in land, water and natural resource development.

Our geotechnical specialists possess extensive experience working with soil and subsurface conditions requiring engineered solutions. Our engineers use their combined experience and knowledge of previous explorations to devise an appropriate method and scope of exploration for your site investigation. Following field exploration and laboratory analysis, the subsurface conditions of your site are evaluated in light of the intended site development. Our repertoire includes pavement design and evaluation, shallow spread footing foundations, mat foundations, driven and auger-cast piles and drilled piers. Ground improvement methodologies, such as dynamic compaction, grouting, soil additives and geosynthetics, have been especially useful tools in our store of methods to conserve your time and money on difficult projects.

Geotechical and CMT Services comprise 45 percent of HSA's gross revenue.

Providing Traditional Services Uncommonly Well

No matter what size your project or stage of development, we offer practical engineering concepts and solutions to difficult subsurface conditions. We remain committed to you by providing expert advice from development inception through design and construction. Our participation during the earliest phases of a project often results in significant cost savings for you, particularly on marginal or difficult sites.
