Selecting an Engineering Consultant

All engineering reports, plans and specifications must be signed, sealed and dated by a Missouri professional engineer. The procurement of planning and design services is one of the most important steps in the design or upgrade of wastewater systems. 

Qualifications-based selection (QBS) is a recommended process to negotiate procurement of an engineering firm based on qualifications and competence relative to the work to be performed.  Below is a link to the QBS proper procurement steps and information provided by the American Council of Engineering Companies (ACEC) Missouri.
