Hirani was retained as part of the survey team to provide comprehensive survey services for three subway stations.  The project was design-build engineering packages to aid in design of multiple ADA-accessible improvements.

A topographic survey used to create a basemap of the road right-of-way which identify roadway profile, utility mark-outs, above ground appurtenances, and elevation grades.  Mezzanine and Platform Levels were scanned and drafted as 3D design elements.  Property lines were determined to establish and identify scope limits for the design-build team.  All design files were extracted, drafted and delivered as 3D MicroStation design files.  All work was completed in New York City Transit Vertical Datum and North America Datum of 1983 horizontal datum.  All work was provided in MicroStation Connect to include a digital terrain model as a surface for the purpose of design.  The NYC Transit 2SR Specifications were followed.
