An EPC project was given to a contractor.He did the design and generated MTO based on his design. We have reviewed and appropved both design and drawings.Now he call for material inspection and during the inspection we found that:
1) the line pipes supplied are welded seam pipes instead of seamless pipes specified on the approved drawings.
2) 60% of the fittings are recycled materials(i.e used materials)
3) 50% of the pipes/fittings have reduce wall thickness due to corrosion as a result of usage.
4) Mill test reports are not traceable to materials.
5) some of the materials have no identification marks.
Project tittle: Fire water system
Line product: water
My Country: Africa-Nigeria
My project manager want the contractor to start work with the materials. Can someone advice me what to do? I want to issue stop work order to the contractor but am affraid of loosing my job.
