DCI Engineers

After a 38-year career, one Seattle Principal is retiring—nearly the entire lifespan of DCI’s 39 years in practice.

DCI’s 636 West 158th Street is nearing completion in Washington Heights, Manhattan, and was recently featured by New York YIMBY, a leading outlet covering real estate development, architecture, and construction in New York City.

This project showcases the kind of structural problem-solving that protects neighboring buildings while delivering a distinctive exterior. Key structural highlights include:

A steeply sloped site (up to 20 feet of grade change) driving stepped pile cap elevations to align with adjacent foundations and avoid undermining nearby structures.

Cantilevered columns and a perimeter ring beam supporting an architectural decorative crown at the second-floor terrace and roofline.

A very deep cellar (19 feet) that transitioned from a planned garage to a lightweight “box” community facility structure built within the completed main shell.

Congratulations to the project team on reaching this milestone. Read the feature HERE: https://newyorkyimby.com/2026/04/636-west-158th-street-nears-completion-in-washington-heights-manhattan.html
