Tectonic Engineering & Surveying Consultants P.C. is providing construction inspection services for the $67M I-86 upgrade of Route 17 in Orange County as part of the NYSDOT’s on-going plan to meet Interstate standards and convert the highway into the designated I-86 by 2012.

The 8.8 mile stretch of highway from Exit 116, at the border of Orange and Sullivan Counties, to Exit 121 in the Town of Wallkill will be milled and resurfaced; including a 3.6-mile section requiring full depth reconstruction and an interchange ramp.

Six bridges along Route 17 are to undergo various repairs and upgrades as well, including the rehabilitation of the Scotchtown Road Bridge and the construction of a new bridge carrying Route 17 over a town road between I-84 and Route 211.

Bridge work will range from joint replacements and pier columns repair; removal of existing steel bridge railings and safety walks; installation of single slope concrete barrier with pedestrian fence; milling existing asphalt or concrete overlay from approach slabs and resurfacing; and replacement of backwalls, pedestals and bearings.

Traffic management strategies will be deployed such as construction phasing, lane closure restrictions and night work to lessen the impact of construction work on commuters.

Tectonic is also providing services involving code compliance for NYSDOT maintenance facilities.

Responsibilities include detailed inspection, on-site field testing of materials, field measurement and collection of data for final payments.
