Kastol Engineering Company

Midtown’s side streets pack more than just high-rises—engineering firms keep the city’s infrastructure humming from offices tucked between delis and design studios. Kastol Engineering Company fits right into that rhythm, offering structural assessments, feasibility studies, and permit expediting without the midtown markup. Their address at 136 W 57th St places them steps from Carnegie Hall and the southern edge of Central Park, a spot where precision matters as much as the projects they handle.

Need a second opinion on load calculations or a fast-tracked approval for a facade alteration? Their team covers mechanical, electrical, and plumbing engineering too. The phone rings at (646) 813-3598; call before you swing by—schedules fill quickly in this neighborhood. For directions, pull up the map and walk from 7th Ave; the building’s glass lobby is easy to spot. Simple as that.
