As-Built Documentation and Modeling is the comprehensive process of creating accurate records of buildings as they actually exist following construction or throughout their lifecycle. Unlike design documentation that shows intended configurations, as-built documentation captures the true constructed reality including dimensional variations, system configurations, and installed equipment. This documentation can range from 2D drawings to complete 3D Building Information Models depending on project requirements. As-built documentation is critical because it provides the accurate facility knowledge needed for renovation planning, system modifications, space management, and regulatory compliance. Without reliable as-built information, future interventions require extensive field verification, introduce significant uncertainty, and increase both costs and risks. Proper as-built documentation preserves essential building knowledge that supports effective decision-making throughout the facility lifecycle while reducing the time and expense of future projects.

We employ multiple information gathering approaches to create comprehensive as-built documentation, selecting appropriate methods based on project requirements, accuracy needs, and building conditions. Advanced capture techniques include 3D laser scanning that collects millions of measurement points with millimeter accuracy, photogrammetry for detailed surface documentation, and mobile mapping for efficient data collection in accessible areas. Traditional methods supplement these technologies with selective manual measurements, condition assessments, and targeted investigations of concealed elements. Existing documentation review integrates available drawings, previous surveys, and historical records with verification of current conditions. For comprehensive projects, we often implement hybrid approaches that combine multiple methods—using scanning for overall geometry, detailed measurement for critical dimensions, and investigations for concealed conditions—ensuring complete documentation while optimizing resources. Throughout data collection, we maintain systematic documentation of information sources, methodologies, and confidence levels to establish clear reliability standards for the resulting as-built records.

We provide versatile as-built deliverables tailored to specific project requirements and intended applications. For 2D documentation, we develop complete drawing sets including floor plans, reflected ceiling plans, building elevations, sections, and detail drawings with appropriate dimensional information and annotation standards. When 3D documentation is required, we create various model types from basic geometric representations to complete Building Information Models with component-specific intelligence and parametric behavior. The detail level ranges from basic documentation capturing primary architectural elements to comprehensive recording of all building components including systems, equipment, and finishes. For specialized applications, we provide integrated deliverables including point cloud references with aligned drawings, photographic documentation with dimensional overlays, and condition assessment information linked to spatial records. The appropriate detail level is determined through careful analysis of project requirements, ensuring deliverables provide exactly the information needed for intended applications without unnecessary complexity or cost.

Our As-Built Documentation achieves exceptional accuracy tailored to project requirements and appropriate to documentation methods. When employing advanced measurement techniques including laser scanning, our standard documentation achieves overall dimensional accuracy of ±15mm (0.6") with critical dimensions typically within ±5mm (0.2"), significantly exceeding traditional measurement methods. For projects using conventional documentation approaches, we maintain industry-standard accuracy of ±25mm (1") with enhanced precision for critical elements. The appropriate accuracy specification is established during project planning based on intended applications—higher precision for manufacturing integration or detailed renovation, standard accuracy for general planning and documentation. Throughout documentation development, we implement quality verification processes including dimensional cross-checking, consistency validation, and comparison against source data. For projects with explicit accuracy requirements, we provide detailed verification reports documenting achieved precision with statistical validation. This accuracy transparency ensures appropriate reliability for all documentation applications while preventing excessive precision costs where not required.

Documenting inaccessible areas and concealed conditions requires specialized approaches that balance factual recording with practical limitations. For areas with restricted access, we employ remote measurement technologies including long-range laser scanning, pole-mounted cameras, and specialized probes that capture information without direct access. When dealing with concealed conditions such as wall assemblies, ceiling plenums, and underground utilities, we integrate multiple information sources including selective investigation openings, available construction records, non-destructive testing results, and industry-standard assumptions appropriate to building age and type. For each concealed element, we clearly identify information sources, confidence levels, and verification recommendations to maintain documentation integrity. Where critical conditions remain unverifiable, we implement appropriate notation systems that clearly distinguish verified information from reasonable assumptions while providing guidance for future investigation. This transparent approach ensures documentation reliability while addressing the practical realities of recording existing buildings without excessive disruption or unreasonable investigation costs.

Our As-Built Documentation process follows a structured methodology refined through extensive project experience. The process begins with detailed planning that establishes documentation scope, accuracy requirements, deliverable expectations, and information gathering methods. On-site data collection combines appropriate measurement technologies, condition assessment, and targeted investigation based on project requirements. For large or complex facilities, we implement phased documentation strategies with systematic zone coverage to ensure complete recording. Data processing transforms field information into organized datasets including registered point clouds, measurement databases, and condition records with appropriate quality verification. Documentation development follows established standards with consistent annotation, dimensioning systems, and information organization as drawing sets or models progress. Throughout development, continuous quality assurance protocols verify dimensional accuracy, content completeness, and documentation clarity according to project requirements. The final production phase includes comprehensive checking, drawing set organization, and deliverable preparation including appropriate metadata, reference information, and usage guidance. This systematic approach ensures consistent quality, appropriate accuracy, and complete deliverables regardless of project scale or complexity.

Our As-Built Documentation provides critical information foundations that enhance both renovation planning and ongoing facility management. For renovation projects, accurate as-built records reduce uncertainty, minimize disruptive field verification, and enable more precise design solutions that properly address existing conditions. This reliable foundation improves construction planning, reduces change orders, and prevents costly field adjustments by identifying constraints and opportunities before design development begins. For facility management applications, our documentation creates comprehensive spatial records, equipment inventories, and system configurations that support maintenance planning, space utilization, regulatory compliance, and future modifications. When developed as intelligent BIM models, these records enable advanced applications including preventive maintenance scheduling, space management automation, and system performance monitoring. Throughout the facility lifecycle, proper as-built documentation provides the accurate building knowledge needed to support informed decisions, efficient operations, and effective capital planning while reducing the time and expense of addressing future facility needs.

Quality assurance is fundamental to our As-Built Documentation methodology, with comprehensive procedures that ensure reliable, accurate deliverables. Our quality management begins with clear project standards including accuracy specifications, content requirements, and deliverable expectations established during planning. Throughout data collection, we implement systematic documentation of measurement methods, information sources, and coverage verification to ensure comprehensive recording. Multi-stage verification protocols include dimensional cross-checking, content completeness review, and consistency validation comparing multiple information sources. For drawing production, standardized templates, annotation systems, and quality checklists maintain consistent documentation standards regardless of project scale. Independent quality control reviews verify both technical accuracy and documentation clarity before deliverable completion. Throughout documentation development, we maintain transparent communication about information reliability including clear identification of verified elements, methodological limitations, and appropriate confidence levels for all recorded conditions. This comprehensive quality approach ensures as-built deliverables provide reliable facility information appropriate to intended applications while clearly communicating any limitations or assumptions incorporated in the documentation.
