Taconic State Parkway, Ramp X, Route 9A/100

Tectonic performed resident engineering, contract administration and inspection services for the NYS DOT’s construction of a new ramp from southbound 9A/100 to southbound Taconic State Parkway, and a new bridge over Route 9A/100.

Construction involved a new concrete deck and curved steel girder single span bridge on pile foundations, approach ramps and embankments, MSE retaining walls, partial cement, concrete, paving, asphalt super pave, drainage, guide rail and pavement markings.

Relocation of an existing pedestrian and bike trail was necessary to accommodate the alignment of the new approach ramp to the bridge. Staging of the bridge erection was coordinated with Con-Ed to accommodate the presence of overhead high voltage lines.

Tectonic’s responsibilities included resident engineering & inspection, contract administration, technical inspections, on-site field testing of materials, field measurement and collection of data for contractor payments, processing contractors partial and final payment estimates, coordination of contractors scheduling, conducting on-site progress meetings, coordinating with outside involved agencies, processing RFI’s, preparation of daily bi-weekly inspection reports, record keeping and as-built plan preparation.
