ZS performed maintenance access/fall protection analysis and design for the Northwestern Mutual Campus Connection (NMCC) project. Designed by famed architect Pickard Chilton, the NMCC is a 32-story glass curtain wall office Tower combined with a two-block long Commons building that is integrated with the company’s historic 1914 headquarters building. The 1.1 million gross-square feet project was completed in 2017.

ZS developed and engineered the maintenance access/fall protection systems for the commons building which included a custom built, one of a kind, MHA unit to access a seven (7) story high atrium glass curtain wall structure. The engineered maintenance access/fall protections systems included:

• A 70′ span Custom Mobile Hoisting Apparatus (MHA) to access all interior glass curtain wall elevations at the atrium.
• Rope Descent System (RDS) Access Rails to access exterior wall elevations at the commons.
• Monorail Trolley Systems.
• Horizontal Life Lines (HLL).
