CME developed the concept plans to replace these highway bridge structures in which the beams were deteriorated beyond repair on a major urban highway in Bridgeport, Connecticut. CME’s design recommended Accelerated Bridge Construction techniques including the use of PBUs (Prefabricated Bridge Units) to replace the existing bridges in a short duration closure of the roadway.
As this was the first Design Build project managed by the Department of Transportation, CME worked with the Department to create the Design-Build process manuals and RFQ/RFP (Request for Qualifications/Proposal) documentation, and other tools in order to make this pilot design-build project a success for the Department. CME also assisted with public outreach and project branding to improve engagement with affected communities, developing the project logo and managing social media during closures.
The Bridgeport Design-Build Project was Connecticut DOT’s pilot Design-Build Project and consisted of the rehabilitation of four bridges which carry Route 8 northbound and southbound. One pair of bridges located over Lindley Street and several spans of a parking lot were rehabilitated by reducing the total number of spans from 7 to 2. The construction involved in-filling the five northernmost spans, converting a pier into an abutment and replacing the remaining superstructure spans with PBUs (Prefabricated Bridge Units) that took advantage of a nearby highway gore area to site cast the units. The second pair of bridges were single span structures over Capitol Avenue and the superstructures were replaced using the same techniques.
Additionally, CME developed extensive highway design plans that detailed the crossover that would occur during construction. The crossover allowed for the closure of alternating highway bounds to accommodate the phases of construction. CME aided in all phases of the procurement process by collaboratively preparing the Request for Qualification (RFQ) documents, Request for Proposal (RFP) documents, RFQ and RFP Process Manuals, and all Departmental review forms and correspondence templates. CME also advised CTDOT in the sensitive analysis of the best value scoring and weighting criteria.
CME assisted with a successful outreach campaign for the Route 8 project using social media; creating an informative, interactive and intuitive project website; and preparing effective PowerPoint presentations and associated support materials (mapping, posters, handouts, etc.) for Public Information Meetings (PIMs). CME also designed the project logo and was responsible for updating content on the project’s social media sites to keep the public informed of traffic impacts and progress during construction.
CME provided owner’s representative services throughout the final design and construction of this project. These services included review of the Design-Build team’s design and submittals for conformance with the contract documents. CME worked closely with CTDOT construction and inspection staff during construction and provided on-site technical support during the accelerated construction periods.
