Consultant Selection Guidelines Document for Lift Stations and Diversion Structures Improvements Project

This is a Consultant Selection Guidelines document outlining the procurement process for engineering services related to the Lift Stations and Diversion Structures Improvements project in Texas, with Project Manager Maria Wang, PE Senior Engineer. The document establishes the evaluation criteria and selection procedures for choosing a qualified consultant to provide comprehensive engineering services including investigation and study, preliminary design, final design, construction plans and specifications development, bid phase services, construction administration, and start-up assistance for modifications, repairs, and replacements at lift stations and diversion structures throughout the jurisdiction. The guidelines detail the consultant selection methodology, evaluation factors, scoring procedures, and technical requirements necessary to assess submittals and identify the most qualified firm to deliver these specialized engineering services.

The selection guidelines establish the framework for evaluating consultant qualifications, experience, project approach, and technical capability through a competitive process. The document specifies evaluation criteria that typically include consultant experience with similar projects, staff qualifications and expertise, proposed methodology, project management approach, and demonstrated understanding of lift station and diversion structure engineering requirements. The guidelines provide a structured scoring methodology to ensure consistent, objective evaluation of all submissions and establish the basis for awarding the consulting contract to the firm best positioned to successfully complete the investigation, design, and construction administration phases of this infrastructure improvement project.
