Ettinger Engineering Associates

Engineering consultants help turn designs into buildable realities; Ettinger Engineering Associates sits at the center of that translation process. At the top end of one of Midtown’s busiest cross-streets, the firm occupies the 24th floor of 505 8th Avenue. Found here: structural studies that shape residential towers and institutional renovations; feasibility analyses for complex retrofits and façade restorations. Plans for new construction in tight Manhattan sites—high-rise additions, terrace expansions—also cross this desk. Shoring up existing buildings forms a large part of the work. Temporary support drawings for adjacent excavations share space with façade inspection reports mandated by local mandates. For owners of pre-war co-operatives, the office prepares Local Law 11 / Façade Inspection Safety Program filings and site-specific safety plans. Roof terrace load calculations feed directly into new permits, while tenant alteration reviews keep proposed work within code constraints before shovels ever hit the ground. Before the first bolt is ordered, the numbers must hold; that’s where the calculations come in—wind loads for slender buildings above subway vents, snow drift studies on setbacks, wind tunnel synopses for slender cantilevers. Energy modeling supports LEED submissions and façade optimization studies; envelope thermal performance reports tie early-stage sustainability goals to final construction details. Call 212-244-2410 for next steps. A precise map takes you straight to the 24th floor at 505 8th Avenue via the elevator banks on the north side of the lobby.
