The brief

A 44-story apartment tower on a tight urban lot, built on a repeating four-day floor cycle with curtain wall and interiors following close behind the structure.

The lot had no laydown space and shared walls with occupied buildings. Every delivery had to be scheduled to a street permit, and the crane served every trade. The developer’s financing depended on hitting leasing milestones, so structure, envelope and interiors had to move together up the tower without stacking trades on the same floor.

How we built it

The approach.

  1. 01

    A four-day floor cycle

    Formwork, rebar, embeds and concrete were planned as a repeating cycle, with crews and crane time fixed for each day.

  2. 02

    Deliveries booked to the minute

    Every truck had a time slot, and the crane schedule was published each afternoon for the next day.

  3. 03

    Trades stacked by floor

    Envelope, rough-in and finishes followed the structure in a planned train, with trade handoffs reviewed in every look-ahead.

  4. 04

    Leasing floors first

    Amenity floors and the lower apartment floors were finished first so leasing could start while the top floors were still in progress.

The outcome.

“On a lot this tight the crane schedule is the project schedule. We published it every afternoon and held to it.”
