Quick Summary<\/strong><\/p>\n

When a Quartzite order is split between two fabricators, responsibility should not stop at each fabricator’s individual scope. Any location where their work must meet needs a named interface owner, one governing drawing revision, agreed dimensions, compatible edge and finish information, traceable piece IDs, and a defined approval route. The goal is not to make one fabricator responsible for the entire project. It is to prevent a shared seam, return, cutout, alignment line, or adjacent component from becoming an undocumented gap between two otherwise correct fabrication packages.<\/p>\n<\/div>\n

A Natural Quartzite project is divided between two fabricators.<\/p>\n

Fabricator A produces the island. Fabricator B produces the perimeter countertops.<\/p>\n

Or one factory fabricates the stone before export while another fabricator completes several pieces locally.<\/p>\n

Each party may understand its own scope perfectly.<\/p>\n

But what happens where those scopes meet?<\/p>\n

That shared condition is the interface.<\/strong><\/p>\n

A split-fabrication project becomes risky when both fabricators assume the other party is controlling it\u2014or when each uses a technically valid but different drawing, dimension, seam detail, edge interpretation, finish reference, or revision.<\/p>\n

Two Fabrication Scopes Need One Interface Record<\/h2>\n

Start by separating three concepts:<\/p>\n

\n
\n

Fabricator A Scope<\/strong><\/p>\n

Pieces, fabrication operations, QC and deliverables specifically assigned to Fabricator A.<\/p>\n<\/div>\n

\n

Fabricator B Scope<\/strong><\/p>\n

Pieces, fabrication operations, QC and deliverables specifically assigned to Fabricator B.<\/p>\n<\/div>\n

\n

Shared Interface<\/strong><\/p>\n

Any condition where the geometry, appearance or installation result of one scope depends on the other.<\/p>\n<\/div>\n<\/div>\n

The interface should not disappear simply because the purchase order has been divided.<\/p>\n

What Counts as an Interface?<\/h2>\n

An interface is not limited to a physical seam.<\/p>\n

For a Quartzite project, it may include:<\/p>\n
