Independent technical oversight

Inspection at Turkish Manufacturers, Fabricators and Project Sites

Turkey has a broad industrial base covering machinery, steel, transport equipment, shipbuilding, energy, process industries and engineered manufacturing.

For international buyers, the challenge is often not simply finding someone who can visit the supplier. The requirement is finding a technical inspector with the right combination of qualification, equipment experience, manufacturing knowledge and project familiarity.

Dilenza can support third-party inspection at:

  • Equipment manufacturers
  • Steel fabrication facilities
  • Pressure equipment manufacturers
  • Piping fabricators
  • Machinery manufacturers
  • Shipyards
  • Rail equipment manufacturers
  • Energy equipment suppliers
  • Industrial construction sites
  • Maintenance facilities
  • Project suppliers

Inspection may take place during a single manufacturing milestone or throughout an extended production program.

Depending on the project, activities can follow the client's:

Inspection and Test Plan · Purchase Order · Technical Specification · Drawings · Project Procedures · Applicable Codes

The scope and inspector responsibilities are established from the controlled project documentation.

The supplier defines the location. The equipment defines the expertise.

The Right Inspector for the Actual Project

Industrial inspection should not be treated as a generic factory visit.

A person may hold the required certification but still lack the relevant equipment, material or industry experience for a particular assignment. Dilenza therefore reviews the requirement before proposing a profile.

Technical Visibility Before Equipment Leaves the Manufacturer

For engineered equipment, waiting until final inspection can be too late to understand what happened during fabrication.

Independent vendor inspection can provide project stakeholders with technical visibility during defined manufacturing stages.

Depending on the ITP and agreed responsibilities, inspection may include attendance during:

Documentation

Review of project-defined documentation relevant to the assigned inspection point.

Fabrication

Technical attendance during agreed production or fabrication stages.

Hold & Witness Points

Presence at defined ITP milestones.

Testing & FAT

Witnessing project-specified testing or Factory Acceptance Testing where included within the assignment.

Repair Follow-Up

Verification of defined repair activities where required.

Final Verification

Inspection at the agreed completion stage before release or shipment.

Inspection frequency can range from one critical visit to recurring surveillance or resident presence.
