The Technical Book of the Construction is a crucial document that compiles and preserves all technical information related to the design, execution, reception, operation, and ongoing monitoring of a building and its associated installations. Its primary purpose is to ensure that anyone who examines the structure, now or in the future, has immediate access to all relevant data needed to identify and evaluate the building’s technical condition as it evolves over time.

Below is an overview of the main components of the Technical Book of the Construction, as set out in Annex No. 6 of Government Decision (H.G.) 273/1994, which approves the Regulation for the Reception of Construction Works and Related Installations.

A. General Centralizer of the Technical Book

Also referred to as the “sheet with synthetic data regarding the construction,” this section provides a concise summary of the entire documentation included in the technical book. It usually contains:

• A general slip of the files making up the basic documentation.
• A set of copies of the slips for each separate file.

B. Design Documentation

Project Background and Location Documents

1. Proof of the design theme (requirements, objectives).
2. Documents describing the location of the construction, including zoning details and site conditions.

Supporting Opinions and Approvals

3. Various opinions or permits that justified and substantiated the development of the project (e.g., environmental clearances, urban planning certificates).

Technical Documentation of the Final As-Built Construction

4. Architectural plans, including any amendments made during execution.
5. Execution details for the load-bearing structure (resistance structure).
6. Installation schemes (electrical, HVAC, plumbing, etc.).
7. Modifications introduced by the designer, builder, or beneficiary during execution, documented through site provisions or supplementary projects.

Calculation Breviaries for Each Specialty

8. Structural analysis, equipment sizing, or other technical calculations.

Recorded Differences from the Original Technical Plans

9. Clear statements of any deviations from the approved technical projects or execution details, including the causes.

Execution Specifications

10. Written instructions regarding work procedures, materials, and quality standards to be followed during construction.

C. Documentation Regarding Execution

Building Permit

1. The construction authorization (autorizație de construire) and any attached plans, which must remain unchanged throughout the project.

Site Handover and Leveling Benchmark

2. Signed minutes of handing over the site and the initial reference points to the contractor.

Reception of Foundation, Structure, and Hidden Works

3. Minutes documenting the acceptance of the foundation soil, the foundations, the resistance structure, and any hidden works.
4. Phase Acceptance for critical stages (fazele determinante) identified in the project and verified by the site supervisor, designer, or authorities.

Technical Expertise (When Applicable)

5. If the construction was not supervised by an authorized site supervisor (diriginte de șantier) or if the required acceptance phases and hidden works minutes are missing, a technical expertise must confirm the quality of execution.
6. Any remediation measures suggested by the expertise and the minutes confirming their correct execution.

Material Quality Documents

7. Quality certificates, concrete condition reports, results of concrete strength tests, and certificates for all materials incorporated into the building.
8. The register of hidden works, inspection notes from control authorities, and the log of directives and site notes.
9. Records of major events (floods, earthquakes, extreme temperatures) that occurred during construction.

Measuring Installations for Monitoring

10. Minutes showing the installation of any monitoring devices specified in the project, including their initial readings that establish the starting point for future measurements.

Additional Documentation

11. Technical expertise, on-site checks, or further research needed due to technical issues, accidents, or design errors (if applicable).

D. Documentation Regarding the Reception of Executed Works

Reception Minutes

1. The minutes drawn up at the end of the works (provisional reception).
2. The final reception minutes issued after the mandatory monitoring period, if applicable.

Additional Documents

3. Any documents required by the reception commission, including verification reports or supplementary research, their findings, and solutions for resolving any identified issues.

E. Monitoring the Construction’s Behavior and Interventions Over Time

Designer’s Written Provisions

1. Instructions on how to monitor the behavior of the structure over its operational lifetime, as well as operation and maintenance guidelines.
2. A list of the basic technical prescriptions to be followed during the building’s usage.

Construction Modification Projects

3. Any changes made to the structure after the final reception must be documented. This includes expansions, redesigns, or retrofits.

Deficiencies and Interventions

4. Records of any issues that appear after final reception, alongside details about corrective measures taken.

Change of Ownership

5. Minutes documenting the handover of the building when ownership is transferred, ensuring the new owner fully understands the building’s technical status.

Why Is the Technical Book Important?

• Long-Term Traceability: It creates a complete history of the construction, from inception to operation, allowing for easy future reference.
• Quality & Safety Assurance: Ensures the building was designed, built, and maintained according to regulatory requirements and best practices.
• Regulatory Compliance: The technical book is required by law, providing a formal record in case of inspections or legal inquiries.
• Property Value & Responsibility: A well-maintained technical book can positively impact property valuation and simplify ownership transfers by providing all necessary data on the structure’s condition.

The Technical Book of the Construction is an essential document for maintaining and verifying the quality, safety, and compliance of any building in Romania. It centralizes all design, execution, reception, and operational records to ensure transparency and accountability throughout a building’s lifecycle. By adhering to H.G. 273/1994 requirements and keeping the technical book up to date, owners, builders, and authorities can ensure a safe, well-documented, and properly maintained construction for years to come.
