The brief

Three hundred twelve apartments built as finished volumetric modules, set six to eight a day and stitched together on site in half the usual time.

The developer wanted months off the schedule and less labor on a crowded site. Volumetric modules had to be designed so structure, plumbing, electrical and fire protection connected cleanly across hundreds of joints. Every module had to be trucked, lifted and set to tight tolerances, and the foundations and podium had to be ready before the first truck arrived.

How we built it

The approach.

  1. 01

    Designed for the factory

    Module sizes, connections and service routes were fixed in the model with the manufacturer before design was finished.

  2. 02

    Site and factory in parallel

    Our crews built foundations and the podium while the modules were being made, taking months off the overall schedule.

  3. 03

    Just-in-time deliveries

    Modules arrived in set order and were lifted straight off the truck, with nothing stored on site.

  4. 04

    Stitch crews on every floor

    Dedicated crews connected services, sealed joints and finished corridors floor by floor behind the crane.

The outcome.

“Every module showed up finished, down to the towel bar. Our job was to set it, connect it and make it look like it had always been there.”
