A successful project ultimately depends on the contractor fulfilling the designer’s intent during construction. Schnabel plays a vital role in seeing a project is built according to plan. We work for the owner in a resident engineer or construction QA/QC role, or for the contractor in a QA/QC role. In both, we advocate for the project’s success by promoting quality and minimizing disputes, change orders, and claims.

Key to our success in this role is a collaborative relationship with our client, maintaining continuous communication, and rigorously documenting construction and testing activities, results, and correspondence. We bring strong design capabilities and experience to this role, strengthening our analyses and recommendations. Our experience includes quality assurance testing for design-build teams, assistance to transportation firms on construction engineering inspection and materials evaluation work, and complete Special Inspections to meet building code requirements for new structures, including soil and materials testing from our in-house AASHTO and U.S. Army Corps of Engineers (USACE) accredited laboratories.
