Case Study: Relay Supply for a construction contractor in North America

Relay for A construction contractor in North America

A construction contractor came to us with a relay programme for North America. The brief was ordinary and unforgiving at the same time: a fixed launch window, a landed cost that had to survive freight and duty, and a part that had to match an existing sample. This case records what was specified, what went wrong in sampling and how the bulk order landed.

The starting point

  • Premature wear on the first batch
  • Warranty claims traced back to a single lot
  • Documentation that arrived after the container shipped

What was specified

PartRelay
ClientA construction contractor
MarketNorth America
Volume50,000 pieces across 4 specifications
Base materialTempered Glass
Sampling rounds4
Delivery window8 weeks from PO to ex-factory
ComplianceIATF 16949

How it was resolved

  1. The specification was rebuilt around Tempered Glass and the tolerance locked before bulk.
  2. A pre-production sample was approved and kept as the golden reference.
  3. Production ran with in-line inspection and a mid-run photo report.
  4. Cartons were packed to the client's own barcode and ratio specification.
  5. Documentation shipped with the goods instead of after them.

Relay production run

Result

  • 50,000 pieces delivered inside the 8-week window.
  • Unit cost held within 1.5% of the original quotation.
  • Inspection-related rejection stayed under 2.0%.
  • The specification is on file, so reorders reproduce the approved sample.

What we would repeat

Approve a pre-production sample made from the actual bulk material. Substitute material behaves differently in service.

Planning something similar?

Send the specification you are working to and we will confirm what we can match, what we would change and why.
