Linking materials and as-built documentation: how PTO digitalization prevents the loss of certificates

In traditional construction management, procurement and as-built documentation processes often operate independently. The procurement department delivers materials to the site and assembles folders containing quality passports and certificates of conformity. These documents are then transferred to the PTO department without a systematic link to the specific types of work and the certificates in which the materials are actually used.

The disconnect between procurement and PTO

In traditional construction management, procurement and as-built documentation processes often operate independently. The procurement department delivers materials to the site and assembles folders containing quality passports and certificates of conformity. These documents are then transferred to the PTO department without a systematic link to the specific types of work and the certificates in which the materials are actually used.

Risks of not digitally tracking materials

The lack of an automatic connection between material registers and as-built documentation creates several objective challenges for a construction company:

• Difficulty finding a certificate: When construction supervision reviews an as-built documentation package, it may require confirmation that the material used meets the applicable requirements. Finding the needed certificate in a paper archive takes a considerable amount of time.
• Risk of document loss: Physical records, such as quality passports and certificates, may be lost during transportation, on-site storage, or handover between engineers as staff changes.
• Register does not match reality: A certificate may reference a material for which no certificate is available or whose certificate has expired. This leads to comments when the documentation is submitted.

Digital integration of materials in a cloud-based PTO platform

Specialized PTO management systems, such as PTO Online, implement the principle of a single materials database. Under this model, every inventory item delivered to the site undergoes incoming inspection and receives a digital record with scanned copies of its quality passports and certificates attached.

How materials are linked to certificates

When preparing an inspection certificate for concealed work (AOSR) or an as-built drawing, the PTO engineer selects materials from the approved register. The system automatically retrieves all supporting documents, including quality passports, certificates, and test reports, and includes them in the as-built documentation package. This eliminates the need to manually search for and scan paper records.

Benefits of centralized document storage

Moving certificates and quality passports to cloud storage provides the following benefits:

1. Instant access: Any PTO engineer can retrieve a certificate at construction supervision's request without having to physically search the archive.
2. Expiration-date monitoring: The system can automatically alert the team when a certificate of conformity is approaching its expiration date, allowing documentation to be updated in advance.
3. Legal protection: An electronic copy of a document with a timestamp confirms that the certificate existed on a specific date, which is important in disputed situations.

Conclusion

Integrating procurement and as-built documentation processes into a single digital environment is an objective direction for the development of the construction industry. Automatically linking materials to certificates eliminates the risk of losing documents, reduces the time required to prepare as-built documentation packages, and improves the transparency of production control.
