Scope of Work:
Numerous improvements to the Croton Harmon Station located on the Hudson Line. Improvements included: removal of the existing concrete platforms and piers; demolition of the existing pedestrian overpass; removal of existing railroad ties and stone ballast; excavation of new stone ballast; construction of new cast-in-place concrete footings and new concrete foundation for a new Southern Overpass. The scope of work for this project also included: installation of new precast concrete platforms and bents for two high level platforms; construction of a completely enclosed pedestrian overpass over three mainline tracks; rehabilitation of all staircases to the existing four passenger elevators. Other work activities consisted of the installation of platform and staircase canopies; railroad signage; furnishings; platform lighting and other electrical amenities. ECCO III also provided a snow melting test section for a portion of one of the platforms. The sequence of construction had to be developed so that all work could be coordinated with Metro North Railroad Operations, such that all construction activities were performed while Metro North was taking one track out of service, 24 hours per day. Even with the many redesigns to the architectural elements of the Southern Overpass structure and numerous other changed designs. ECCO III Enterprises, Inc. reworked the project schedule so that it was still completed ahead of the original contract schedule.
