2 servicesHow we fit your project
From supplier selection to site acceptance
Most quality and delivery failures are visible early to someone standing in the supplier's workshop. Our services are organised along the procurement lifecycle, so each phase has the right control.
PHASE 01
Supplier selection
Capability and process audits before award, so the sourcing decision rests on what the supplier can actually do.
PHASE 02
Engineering review
Drawings and specifications reviewed for clarity and feasibility. Technical queries resolved before production starts.
PHASE 03
Kick-off and ITP
Pre-inspection meeting, quality plan and ITP agreed, hold and witness points defined, schedule baselined.
PHASE 04
Production surveillance
Material, in-process and welding inspection at the stages defined in the ITP. Nonconformities managed to closure.
PHASE 05
Expediting
Verified progress of procurement, manufacturing and documents against the schedule, with early escalation of risk.
PHASE 06
FAT and testing
Factory acceptance tests, pressure and functional tests witnessed, NDT reviewed, punch list managed.
PHASE 07
Release and shipment
Final and pre-shipment inspection, documentation review, packing and loading supervision, inspection release note.
PHASE 08
Site and handover
Installation inspection, SAT and commissioning support, local representation and handover documentation.
Positioning
Your technical presence inside the Turkish supply chain
Buyers in Europe, North America and the Middle East source castings, forgings, machined parts, fabrications, machinery and engineered equipment from Turkey. The opportunity is real: capable suppliers, short lead times and proximity. The risk is distance. Problems that are obvious on the shop floor are invisible from an office abroad until the shipment arrives.
QUALITAS TR closes that distance. We are engineers based in Ankara who inspect, audit, expedite and manage projects on behalf of buyers, with reports written for decision makers. We are not the supplier's consultant and we do not sell certificates: our only client on a job is the party that appoints us.
Inspection
Is it right?- Verifies conformity to drawings, specifications and codes
- Works to the ITP and acceptance criteria
- Output: inspection report and release note
- Authority: accept or reject against criteria
Expediting
Will it be on time?- Verifies physical progress against the schedule
- Follows materials, sub-suppliers and documents
- Output: progress report with forecast dates
- Authority: escalate and follow recovery
Project management
Is the whole project under control?- Plans and coordinates scope, interfaces and risks
- Integrates engineering, quality and schedule
- Output: status reports and decisions needed
- Authority: coordinate within the agreed mandate
Engineering management · Project management · Expediting
Engineering, project and schedule control, not only inspection
Many inspection agencies stop at accept or reject. Our scope continues into the technical and project questions behind the result: is the drawing clear, is the tolerance feasible, is the change controlled, is the material on order, will the FAT happen on the planned date?
Engineering management, project management and expediting are offered as distinct services with their own deliverables, and combined with inspection when that gives you the best view of an order.
Expediting dashboard: planned versus actual progress
Weighted manufacturing progress of a fabricated equipment order with milestone markers. Select a scenario or a milestone.
Expediting compares verified physical progress with the agreed schedule and flags delivery risk early.

SPC individuals chart: bore diameter Ø25.000 mm
Control limits calculated from the first 15 samples. Select a scenario, then a point.
An individuals chart plots each measurement against limits at three standard deviations from the centre line.
Risk matrix: severity versus occurrence
A simplified 5 x 5 matrix used to rank supplier and process risks before an inspection plan is set. Select a cell.
Rows: occurrence. Columns: severity.
Higher scores call for stronger controls: hold points, 100% checks or process changes.

Why QUALITAS TR
Principles you can hold us to
We prefer commitments we can be measured against to adjectives. These are the principles behind every QUALITAS TR job.
Independence
We work for the party that appoints us. We do not accept fees from the supplier being inspected, sell consultancy to it on the same job, or approve our own work. See our independence policy.
Engineering judgement
Inspections are led by engineers who understand how the product is made: metallurgy, welding, machining and quality engineering, not checklists alone.
Facts in every report
Measured values, photographs, references to the document revision used and a clear verdict. Findings are classified and traceable.
Defined scope, honest limits
Every proposal states what we perform, what we witness and what we coordinate through qualified third parties. We never present partner capabilities as our own.
One accountable contact
One engineer or coordinator for your order, who knows the product, the supplier and the history, and answers in English.
Direct communication
No forms and no call centres. Email or call us and an engineer answers.
