Testimonials

“SCI demonstrated its comprehensive, one-stop organization (Geotechnical, Environmental, Natural Resources, Cultural Resources and Construction Materials Testing), when the Edwardsville School District experienced major soil issues at Liberty Middle School, Goshen Elementary and Cassens Elementary School. SCI’s quality team found solutions to the problem and remained on-site with constant monitoring until the issue was resolved and the project completed. I would recommend SCI for your upcoming project.”

“We at Oculus were very fortunate to have SCI Engineering on our team on the VISN 15 IDIQ Contract for the VA. Their team was instrumental in helping provide our client with what they needed in the areas of industrial hygiene services. SCI’s high standard for customer service was evident throughout the entire duration of not only this project, but others we’ve worked on with them in the past. It is without hesitation that I would recommend working with them in the future.”

“Your team was an asset to the recent Fort Leonard Wood hospital replacement, especially dealing with our two sinkholes, and unique slab design. I have no doubt that you all will provide the same level of service and professionalism to other ownership teams.”
