His forensic cases have occurred in approximately 40 states, have included intellectual property and patent factors, and have involved allegations concerning approvals, personal injury, damages, illegal facilities, and the correction of problems.

Approximately 40% of his professional time has been spent providing expert witness services nationwide for over 45 years. Approximately 45% of his expert witness services have been for defendants and about 55% for plaintiffs. Despite the generally narrow technical focus of Heritage and that it is unusual for attorneys to have more than one case within Mr. Dutill’s expertise, combined with Heritage having cases in approximately 40 states, Heritage has had 3 clients for more than 25 years, 7 other clients for 15 to 24 years, and 12 other clients for 5 to 14 years, from the commencement of to the conclusion of services or to the current time, as appropriate. As indicated in feedback from attorneys on expert witness cases, some of the strengths of Mr. Dutill include understandable guidance, responsiveness, timeliness, communication, effective report writing, strong testimony (including on cross), efficiency, organization, and assistance with framing case issues.

Both as principal of Heritage Technical Services in the Philadelphia, Pennsylvania area and as a member of two distinguished international civil and environmental engineering firms, the hydrology, civil engineering, and environmental engineering work of Mr. Dutill has been heavily concentrated in:

• provision of expert witness services, including investigation, analysis, consultation with counsel, expert reports, and expert testimony
• analysis of regulations, including concerning compliance and enforcement
• evaluation of monitoring requirements
• development of engineering feasibility studies and facility plans
• acquisition of permits with appropriate requirements and fees
• provision of project cost advice

He also has significant engineering experience in the areas of design, construction management, operations assistance, maintenance, and community acceptance. Serving as an environmental engineer, civil engineer, and hydrologist on a consulting basis for private, institutional, and governmental clients, Mr. Dutill has expertise in hydrology, stormwater, wastewater, hazardous waste, potable water, solid waste, and air quality issues.
