AGS specializes in providing one-stop geo-solutions on all size projects:
RESIDENTIAL, COMMERCIAL, MUNICIPAL.
Our one-stop solution includes not only geotechnology but also landslide & slope technology, foundation engineering, earthquake engineering, and civil/drainage/groundwater engineering, and geostructural designs. AGS takes pride in providing high-quality and cost-effective solutions in a timely manner. AGS is uniquely qualified to also offer you consulting services on design-build projects including contract management and quality control services. These capabilities offer convenience and assurance of a “one phone call” service.
What are the benefits of using an 'expert' and an 'insured' consultant ? 
We have many decades of cumulative and successful group experience which makes us an expert.  We carry $1,000,000.00 / $2,000,000.00 E&O insurance coverage from an established and highly ranked coverage provider.  An expert consultant can perform a thorough investigation which almost always results in reducing construction costs.
​
​What are the benefits of spending adequate resources on geo-investigations?
The cost of geo-investigation almost always pays for itself, in addition to saving significant monies which would have been spent due to over-design and poor performance of structures.
Why engineering service is not a commodity and 'you get what you pay for.'
The cost is based on many factors such as the scope of field exploration, number of laboratory tests, rigor of analyses, and how comprehensive and in-depth reporting is. If you choose the lowest cost service, you will almost certainly get a low quality report and cost of construction will increase, sometimes by thousands of dollars due to lack of design optimization.  At AGS, we take pride in providing in-depth reports based on analytical rigor and optimization methods so you get the best recommendations which lead to lower construction costs, in most cases.
