Apple Store, Market Street, Lynnfield MA

Fast-track project. Custom tapered girders to create thin-profile hip roof. Client pushed for early mobilization ASAP. We communicated to project team the benefits of allowing us to take an extra week to fabricate large roof truss assemblies to limit erecting time. This enabled the project to gain an extra two weeks of schedule by accelerating additional concrete work for underground MEP that otherwise had to start after steel erection.
