CME prepared design plans for this fast-tracked roadway reconstruction project of Ocean Avenue in New London. The project was funded under the Local Transportation Capital Improvement Program (LOTCIP) and our team delivered the design plans within 3 months of the contract signing to meet program requirements.
CME saved the City over $100,000 by performing a FHWA Manual on Uniform Traffic Control Devices (MUTCD) signal warrant analysis that revealed replacement of traffic signals was not necessary, as originally scoped.
Design included reclamation and repaving of the roadway; repairs to sidewalks, driveway aprons, ramps and curbing; addition of bike lanes and improvements to drainage infrastructure. CME also specified the use of soil additives in the sub-base in order to maximize compaction during construction and provide extra protections for icing roadways in the harsher winter months.
The surface of Ocean Avenue was uneven and deteriorating due to numerous utility crossings and poor drainage. The slope of the northern portion of the roadway was very flat (less than 1%) and did not include any drainage structures. This caused many areas of shallow ponding that were contributing to pavement and subbase failures as well as creating safety concerns during rain and snow events. The purpose of the project was to reconstruct the roadway and include adequate drainage to prevent future damage and improve safety for motorists during wet weather conditions.
The project involved the design of approximately 0.85 miles of collector roadway in a residential area including repair and replacement to sidewalks, installation of bike lanes and drainage improvements. CME provided comprehensive services for this project including land surveying; coordination with utility companies; design; storm drainage; environmental documentation; permitting and bidding assistance. CME prepared specifications, cost estimates and construction documents including signage and pavement marking and maintenance and protection of traffic plans.
In addition, CME was to provide the design of traffic control signal replacements at two (2) intersections, however, CME performed a MUTCD signal warrant analysis and found that installation of signals at both intersections were no longer warranted. At CME’s recommendation, the city removed the signals from the project saving over $100,000 on the project.
