Amazon’s North Andover Fulfillment Center is a large warehouse steel detailing assignment in North Andover, Massachusetts. Moldtek handled 17,000 tons of steel for the core warehouse frame and its bracing, plus a deep miscellaneous-steel scope: elevator guide-rail post supports, dock-leveler embeds, galvanized canopies, roof platforms, opening frames, handrails, and girt structures, all coordinated across joist, panel, precast, and mechanical trades. A team of 26 to 30 detailers ran the package on a compressed 16-week schedule, with disciplined drawing release keeping high-volume deliverables on milestone.

The complication on the North Andover fulfillment center wasn’t the shape of the structure. It was volume and interfaces, on an aggressive clock — large member sizes, multiple related trades, and a stack of support packages, all inside a compressed 16-week programme.
Heavy W-shapes and plate girders had to be coordinated with wide-flange beams and braced frames.
Joists, roof deck, wall panels, and precast elements all had to align with the steel framing.
Guide-rail post supports, plates, clips, and embeds needed detailed modeling and embed coordination.
Accurate embeds, opening frames, and support angles had to serve the dock equipment and the MEP trades.
High-volume deliverables meant strict milestones, RFIs, and revision management.
Moldtek sequenced the work into major packages and ran a 26-to-30-person team against defined deliverables, level of detail, and responsibilities.
The core steel, the embeds, the opening frames, and the misc. steel all moved through coordination review without stalling the drawing release.
Joist, panel, precast, and mechanical coordination resolved in a controlled order rather than all at once against the deadline.
Drawings were quality-checked and issued as IFC models, shop drawings, and reports for fabrication and erection.
With high-volume deliverables on strict milestones, drawing control — RFIs, coordination items, and revision management — kept the package releasing on schedule rather than bunching up at the end.
The warehouse frame was detailed on Moldtek’s standard toolchain and delivered against US structural codes, so shop and field teams received erection-ready models and drawings.
Scope clarity, interface coordination, and schedule discipline converted a complex warehouse steel package into buildable deliverables that supported timely release and multi-trade alignment.
A clear breakdown of main steel, miscellaneous steel, embeds, and opening frames.
Better control over bracing, canopies, roof platforms, and support conditions.
Strong follow-up on RFIs, coordination items, and drawing release.
