As-Built Drawings & Job Book Development

Documenting Every Detail for Long-Term Success
Accurate project documentation is essential for the ongoing maintenance, regulatory compliance, and future upgrades of pipeline systems. Liu Engineering’s as-built drawing and job book development services provide a complete, detailed record of every aspect of your project—from initial design modifications in the field to final documentation delivered to the client.

Field Verification and As-Built Markups
During the construction phase, changes and deviations from the original design can occur. Our team conducts rigorous field verification to capture all modifications:
• On-Site Measurements: Collecting detailed measurements and verifying the actual installation against design specifications.
• As-Built Markups: Updating CAD drawings and other design documents to accurately reflect the final installed conditions.
• Photographic and Digital Records: Maintaining comprehensive records, including photographs, digital scans, and inspection reports, to support the as-built documentation.

Developing Detailed CAD Drawings
Our engineers convert field data into precise CAD drawings that serve as the definitive record of the project. These as-built drawings include:
• Pipeline Layouts and Routing: Detailed maps and schematics showing the exact route of the pipeline.
• Facility Designs: Updated drawings for meter and regulator stations, launcher/receiver facilities, pump/compressor stations, and other installations.
• Utility and Ancillary Systems: Documentation of all related systems such as electrical, instrumentation, and safety systems.

Job Book Development and Turnover Packages
A comprehensive job book is a critical deliverable that encapsulates the entire project:
• Engineering Reports and Test Records: All reports, test results (including hydrotest data), and inspection certificates are compiled.
• Material Certifications and Weld Logs: Documentation of all materials used, weld procedures followed, and quality control records.
• Operation and Maintenance Manuals: Detailed guides to help operators manage and maintain the pipeline and facilities over the long term.
• Regulatory Submissions: Complete documentation packages prepared for submission to regulatory bodies, ensuring that the project meets all compliance requirements.

Digital and Physical Archive Management
To support long-term asset management, we provide both digital and physical archives of all project documentation. This ensures that critical information is readily accessible for future reference, audits, or system upgrades.

Benefits to Pipeline Operators
By providing comprehensive as-built documentation and detailed job books, Liu Engineering helps pipeline operators:
• Maintain Accurate Records: Essential for ongoing maintenance, inspections, and regulatory compliance.
• Plan Future Upgrades: Detailed records facilitate effective planning for future modifications or expansions.
• Streamline Asset Management: Easily accessible documentation supports efficient operational decision-making.

Our Commitment to Quality Documentation
Liu Engineering’s meticulous approach to documentation is part of our overall commitment to quality and excellence. Our as-built drawings and job books are more than just paperwork—they are an integral part of the project’s lifecycle that ensures continued safety, reliability, and performance.
