The Algoma Melt Shop Building is a major industrial steel detailing assignment in Sault Ste. Marie, Ontario — a high-tonnage steel-melt shop. Moldtek is handling 12,000 tons of main steel, miscellaneous steel, girt steel, and four stair towers, broken into roughly 30 controlled sequences so a connection-intensive structure can be detailed, reviewed, and released without losing momentum. The assemblies run heavy, 20 to 80 tons, and the work turns on splice detailing, heavy connections, and disciplined RFI and CDQ tracking across a 50-week structural steel detailing programme.

The difficulty in the Algoma melt shop was never a tall frame or a tight site. It was weight and connections. High-weight assemblies, trusses, girts, stair towers, and peripheral framing all demanded careful detailing and constant issue resolution across a large industrial melt shop environment.
Splice detailing across major steel members required careful control — get a splice wrong on paper and it becomes a fit-up problem in the field.
Heavy truss assemblies demanded robust connection detailing and review before they could be released.
Peripheral girt interfaces required accurate fit-up and coordination with the cladding and boundary conditions.
Edge conditions and support interfaces added detailing complexity that couldn’t be treated as typical.
Open technical queries were critical to manage to keep deliverables moving on an active build.
The building was divided into roughly 30 controlled sequences across its process, main-frame, peripheral-girt, and support/access zones — the structure that let the team break down high-weight assemblies and hold momentum.
Column and truss splices, girt interfaces, and deck-support conditions were handled inside the sequenced structure rather than all at once.
Open items were tracked through weekly status reporting, resolved in a controlled order rather than piling up against the drawing release.
Quality-checked drawings were issued for construction sequence by sequence, keeping an ongoing build moving.
Because the model is sequenced into roughly 30 packages, detailing progress stays visible sequence by sequence, and weekly status tracking keeps the RFI and CDQ log current — so on an ongoing build, everyone can see what is modeled, checked, and ready for release.
The melt shop is detailed on Moldtek’s standard toolchain and delivered against US/Canadian structural codes, so heavy assemblies and splice-intensive connections release fabrication-ready.
Sequence discipline, connection clarity, and structured issue tracking translate a high-tonnage industrial steel package into coordinated deliverables that support fabrication planning and timely drawing release.
A clear breakdown of main steel, miscellaneous steel, girt steel, and the four stair towers.
Better control over heavy-assembly detailing and the welding-intensive zones.
Strong follow-up on RFIs, CDQs, and weekly status tracking keeps the build moving.
