If it doesn't fit in our shop, it doesn't leave our shop.
Every major QB structure is trial-assembled before shipment: pre-built, measured, and verified, so the component that arrives on your site installs the way the drawings promise. Field failures don't begin in the field. They begin in fabrication shops that ship unverified steel. QB doesn't.
Trial assembly, from above.
Drone footage of lattice sections bolted together at QB's Clackamas facility. This is the proof behind every shipment.
A field failure costs more than the entire fabrication contract.
On critical transmission and substation projects, a member that doesn't fit in the field triggers schedule delays, crew downtime, safety exposure and procurement accountability. Trial assembly takes that risk out of the field and absorbs it inside our shop, where it can be solved without consequence. Zero surprises is not a slogan. It is the operational proof behind every QB shipment.
Risks resolved upstream.
- ×Misaligned bolt holes discovered
- ×Tolerance stack-up across multi-piece assemblies
- ×Schedule slippage cascading to interconnect dates
Fit and tolerance verified before shipment.
Trial assembly at QB's Clackamas yard gives utilities and EPC partners confidence that critical assemblies will fit in the field.
Six steps from drawing to verified delivery.
Additional process detail, catch-rate evidence, and field-outcome examples will be added as trial assembly intake documentation is completed.
Shop Drawing Review
Engineering coordination and detail review before steel is cut, identifying buildability and interference risk early.
Fabrication Under Controlled Procedures
Welding, drilling and forming executed under documented WPS and qualified welder programs.
Trial Assembly
Critical assemblies bolted together in our shop. Tolerances verified and fit confirmed before shipment.
QA/QC Inspection
Visual weld inspection and dimensional verification documented per project specifications.
Match-Marking & Documentation
Components match-marked, photographed and packaged with traceable records that follow the steel to site.
Coordinated Delivery
Logistics integrated with field schedules so steel arrives in the order it installs.
Quality you can audit, not just claim.
Every project ships with documented quality records. Inspection is integrated into fabrication, not appended after the fact.
Records that move with the steel.
From mill test report to photographed trial assembly, every component arrives with a documented history. When auditors, engineers or field crews ask, the answer is in the file.
- Material traceability to mill heat numbers
- Welder qualification and WPS records
- Inspection reports and dimensional data
- Photographic trial assembly evidence
