External auditing is done by a team from the contractor or the service provider. A company that takes the ISO should also be a company whose products and safety can be trusted. But, in reality, in some countries, such a list is nowhere to be had, while companies in other countries have the ISO but do not apply any of the system for quality assurance, as most of the companies are focused on quality control rather than on quality assurance or even on developing a quality manual.
Therefore, in major projects, the owner may consider forming a team from his own company’s quality department to conduct
external audits for other engineering or contracting services providers.
First, the contractor or other service provider delivers his quality manual for review by the quality team. They visit the site with a company representative to show their system in action and to inspect it. The process is as follows:
• the Supplier’s site is visited and a complete inspection performed;
• the Supervisor gives the visiting team an exact description of how their Q. C. system works;
• the contractor supplies examples of Q. C. documentation;
• the inspection team may ask to re-check a previously inspected batch;
• test equipment is checked for regular maintenance; and
• rejected or unacceptable products are clearly marked and segregated to avoid any chance of their accidental inclusion with acceptable products.
Three possible outcomes may ensue following this visit:
1. Acceptable to be registered in company bidder list
If the evaluation has shown that the supplier has a satisfactory Quality Management System (QMS), there are no deficiencies and the supplier is able to give an assurance of quality.

Also, in this case the supplier may have proven that they are up to satisfactory standards.
2. Weak Quality System
If the team finds several significant weaknesses in the supplied s system, the supplier will have to take steps to overcome these failures and improve their QMS.
The supplier can ask for another evaluation to confirm that their quality is approved. To enhance their company and employee work will take time, so it is not preferred to register the company but to give it a period to change.
3. Unacceptable Quality System
In this case the team found that the supplier will have to make radical changes to improve their overall QMS.
Note that in this case the actions from the supplier to reach the target to satisfy Q. M.S. will take not less than one year, so avoid dealing with this supplier.
ISO 9000 provides a check list that is essential and important for the auditing team. The following is the check list for every phase of the project. In the design phase there is a sample for what will be asked from the engineering company. For the construction phase, this check list is tailored to be a sample when auditing a contractor company.
From the above, and indeed as stated in ISO 9001 section 4.18, it is clearly important that all project employees possess appropriate technical skills as well as a QMS. Training may be required to increase these skills levels to the standard required.
