CME serves as a Consultant Liaison Engineer (CLE), acting as an extension of Connecticut DOT staff, assisting in their delivery of two bridge programs, involving bridges on State routes and Town roads throughout the state. CME has served in this role since 2011 and has overseen approximately 80 bridge improvement projects. While providing overall management for each assignment, services have included concept planning, preliminary engineering and project development, Designer oversight, and support through construction.
CME works closely with CTDOT to identify and improve systems, processes, and tools to better deliver this important program Statewide. CME has also brought new methods and technologies to the program which minimize project impacts to the public, extend bridge service life and minimize project costs. Through the CLE Program, CME has introduced the use of GRS-IBS as an economic and durable solution for building bridge substructures. We have also recommended the use of Ultra High-Performance Concrete (UHPC) for beam end repairs. In addition to new construction techniques, CME developed a standardized decision matrix for assessing the feasibility of using Accelerated Bridge Construction (ABC) for projects. As an example, our CLE team recommended and successfully-guided the design and implementation of CTDOT’s first Lateral Slide bridge superstructure, an ABC technique that has gained attention for its notable success nationwide in recent years.
Since 2011, CME has worked as an extension of CTDOT staff, managing the project schedule, design phase and design support during the construction phase of bridge rehabilitation projects under the State List Bridge and Federal Local Bridge Programs. CME manages these projects from initiation through construction completion, with upwards of 40 projects underway, simultaneously, at any given time.
For each bridge assigned, CME conducts a rehabilitation study to identify bridge deficiencies, project scope and goals, project constraints and cost-effective solutions. Preliminary engineering is developed by the CME team which includes alternative design strategies to address project challenges, offer ways to accelerate construction/minimize user impacts and save money. CME’s team, along with their Subconsultants, provides numerous services during the study phase including: visual inspection, non-destructive testing, highway geometrics, traffic analysis, hydraulic/scour analysis, structure load rating, utility coordination, geotechnical investigation, survey and mapping.
Once an option is selected, CTDOT assigns the design phase to an on-call engineering consultant for completion and CME oversees their performance of the design and preparation of bid documents. While design is underway, our team prepares environmental permitting documents and coordinates with various utility companies, railroads, and other state, federal, and local agencies.
Additionally, the CME team technically and administratively reviews design submissions; performs hydraulic analysis, provides geotechnical engineering, reviews structure load ratings, reviews invoices; coordinates tasks and activities; schedules and facilitates meetings; manages the project schedule and assesses budgets; prepares correspondence; manages design support during construction, and maintains all project records. The team leads stakeholder and public outreach efforts to educate and inform communities of expected impacts and mitigation measures.
