As-Built Drawing Services Professional Facility Documentation for Renovation & Compliance
Transform your facility documentation with our comprehensive as-built drawing services. We deliver accurate as-built drawings documenting the exact installed condition of buildings and facilities—helping facility managers, building owners, architects, and engineers support renovations, facility management, and regulatory compliance.
Whether you need as-built floor plans for renovation planning, MEP documentation for compliance, or complete facility record drawings, our team delivers reliable as-built documentation that supports your project success.
What Are As-Built Drawings?
As-built drawings document the complete physical installed condition of a building or facility as it actually exists. Unlike original design drawings, as-builts reflect all field changes, modifications, and substitutions made during construction.
The gap between what drawings say and what actually exists in a facility grows every time a modification gets closed out without a document update. It compounds quietly until a renovation, an audit, or an expansion project makes the scale of it visible all at once.
As-built drawings are essential for:
- ✅Renovation and retrofit planning – Understanding existing conditions
- ✅Facility management and operations – Maintaining accurate records
- ✅Regulatory compliance and safety documentation – Meeting OSHA PSM requirements
- ✅Asset management and record keeping – Tracking facility assets
- ✅Contractor bidding and coordination – Providing accurate information
- ✅Property transactions and due diligence – Supporting property sales
As-Designed vs. As-Built
Understanding the difference between as-designed and as-built documentation is essential:
The gap between design and reality grows every time a modification gets closed out without a document update. A proper as-built program goes back to the physical asset, measures it, scans it, verifies it, and produces documentation that reflects what's actually there. That's the only version worth trusting.
| PARAMETERS | AS-DESIGNED | AS-BUILT (ACTUAL) |
|---|---|---|
| Focus / Objective | Design intent before construction | Actual installed condition after construction |
| Field Modification Status | May not reflect field updates or redlines | Captures all changes, substitutions, and updates |
| Facility Management Utility | Often incomplete and outdated for operations | Essential for reliable maintenance and OSHA compliance |
| Creation Timestamp | Created before construction commences | Created after construction is finalized |

Capture Methods
We use multiple methods to capture accurate, reliable as-built data:
Laser Scanning (3D)
3D laser scanning captures millimeter-accurate point cloud data. We deploy terrestrial scanners across the facility—live plant or shutdown—and capture millions of data points per setup. The result is a millimeter-accurate point cloud that becomes the master spatial reference for everything downstream.
Laser scanning offers:
- ✓ Millimeter accuracy (2-4mm)
- ✓ Million+ data points per scan
- ✓ Complex geometry capture
- ✓ Faster field time
- ✓ Reduced drafting rework
| PARAMETER | LASER SCANNING | MANUAL MEASURE |
|---|---|---|
| Accuracy | Millimeter accuracy | Less precise |
| Data density | Million+ data points | Limited data points |
| Geometry handling | Complex geometry capture | Simple geometry |
| Field efficiency | Faster field time | Slower field time |
| Upfront Cost | Higher upfront cost | Lower upfront cost |
Deliverables Included
Every drawing package contains clear, precise as-built sheets ready for integration and building audits.
Our As-Built Drawing Workflow
Our process pairs state-of-the-art capture technology with multi-stage QC reviews to guarantee precision.
Site Assessment & Scope Definition
Before mobilization, we review your existing document register in detail. Drawing quality, revision status, coverage gaps—all of it gets mapped. The scope boundary gets defined area by area, system by system. Ambiguity here costs money later.
Field Data Capture
Laser scanning and targeted manual survey run in parallel where access allows. Our field teams work to a structured capture plan—every area, every deck, every congested pipe rack accounted for. We coordinate access directly with your operations team so field work doesn't interfere with production.
Data Processing
Scan data gets registered into a unified point cloud model, cleaned, and handed to our drafting team. CAD outputs—plans, sections, elevations—are extracted directly from verified scan geometry. No guesswork, no approximations.
Drafting & Review
All drawings are reviewed against the registered point cloud and project requirements to confirm alignment, completeness, and consistency before delivery. Our experts verify accuracy and completeness.
Delivery & Document Control
Final deliverables are packaged to your EDMS requirements. File naming, metadata, revision status, transmittal register—all structured to drop directly into your document control system without a manual re-sort.
Our Technology Stack
We work with industry-leading software to ensure compatibility with your project requirements.
Regulatory Compliance
We ensure all as-built documentation meets applicable code and regulatory requirements. Our processes conform to rigorous international frameworks to guarantee drawings are audit-ready and safety-compliant.
| STANDARD | ORGANIZATION | APPLICATION |
|---|---|---|
| ISO 19650 | International Organization for Standardization | Information management for built assets |
| OSHA 29 CFR 1910.119 | OSHA | Process Safety Management (PSM) |
| ASME B31.3 / B31.4 / B31.8 | ASME | Piping documentation |
| AIA Standards | AIA | Architectural documentation |
