Expert Witness










HG Cornerstone’s construction and civil engineering expert witness services include:

HG Cornerstone’s construction expert witness and civil engineering expert witness services are based upon our extensive experience spanning almost three decades in building design, engineering and construction, allowing for the numerous and varied types of construction and property damage issues that we can competently consult on.

We begin each new assignment with the end goal in mind…

Our construction expert witness and civil engineering expert witness services begin with an initial case consultation and we tailor the scope of our expert witness services around the technical aspects, size, and dollar value of the alleged claim. At HG Cornerstone, we are also innovators in implementing legal support cost controls for our clients.

Our approach is to carefully define the issues and to develop an agreed-upon strategy, pre-defined work scope, and set of deliverables.

It’s all in the execution…

Our execution involves providing the most comprehensive investigative and assessment work, including sound fact-based research, and offering the most knowledge-based information, assessments, evaluations, testing, opinions, and conclusions possible. Let us help you develop a truly winning strategy.
