What our clients say

City of Columbus

I am delighted to recommend DHDC Engineering Consulting Services as a qualified firm to provide Geotechnical, Subsurface Utilities Engineering (SUE), construction materials testing, and inspection services. DHDC Engineering has provided successfully those services to the City of Columbus for the last few years. DHDC Engineering has attention to detail in mind, and always provides high quality work. DHDC Engineering has played a key factor to the success of many of our projects and we look forward to working with them in the near future.

I have known Savvas Sophocleous personally and he has always been instrumental in making sure the needs of the City are met. Please do not hesitate to contact me at 614 645-0584, if you need any further information.

Franklin County Engineer

In 2012 and 2013, DHDC performed soil borings and submitted a Geotechnical Subsurface Investigation Report for a proposed storm sewer casing under CSX RR along Trabue Road. The report included a description of the subsurface soil and groundwater conditions as well as construction recommendations for the proposed storm sewer casing. In 2016 DHDC performed soil borings for Thoburn Road Improvements following ODOT Geotechnical Procedures.

Savvas Sophocleous was our main point of contact. Savvas' reports for both projects were complete, accurate, and delivered early. He was always quick to respond to questions or requests for information made via telephone or email. He provided very good service, and the fees he charged were reasonable and fair.

As the need for additional Subsurface Investigations arise, we look forward to the prospect of hiring DHDC Engineering Consulting Services, Inc. for their high quality geotechnical work, and we strongly recommend them to anyone requiring such services. Any additional questions regarding our work with DHDC may be directed to Cornell Robertson at (614) 525-3080.

City of Upper Arlington

I am honored to recommend DHDC Engineering Consulting Services to provide future services for your Engineering and Construction service needs. DHDC has been providing construction materials testing services along with other various engineering/construction services to the City of Upper Arlington for the past decade.

We have worked directly with Savvas Sophocoleous for the past several years, during which time we have collaborated on many construction projects in Upper Arlington. His attention to detail and his personal involvement with all aspects of the services provided helps to create the best possible customer service from DHDC.

DHDC provides us with quick responses to our needs and at the same time provides us with the lowest prices available. In working for government entities, it is rare to find such excellent customer service at the low bid pricing that DHDC can provide. For these reasons, I expect that DHDC will continue to be our top choice for construction materials testing and other related consulting services for a long time in the future.

I would be happy to discuss our past experiences with DHDC with anyone who is interested in learning more about them. You can contact me at JThiel@uaoh.net or by phone at 614-583-5360.
