Virtual Design and Construction (VDC) is a methodology used to plan and manage projects using digital models before anything is built physically. It combines tools like Building Information Modeling (BIM), data analysis, and collaborative workflows to simulate how a project will be designed, constructed, and operated.
Instead of relying only on 2D drawings, VDC creates detailed 3D models that integrate geometry, scheduling, and cost information. This allows project teams to detect clashes, optimize sequencing, and make informed decisions early in the process.
The main goal of VDC is to improve efficiency, reduce risks, minimize rework, and enhance collaboration among stakeholders. By virtually “building” a project first, teams can identify problems before construction begins, saving both time and money.
Laser Scanning
Laser scanning uses high-speed laser beams to capture precise distance measurements, converting physical environments into dense point clouds for accurate 3D representations of buildings, terrain, and objects.
- Document Existing Conditions: Capture precise baseline data for renovated or existing structures.
- Verify As-Built Work: Measure construction progress against design specs to spot discrepancies early.
- Support Design & BIM Workflows: Generate accurate 3D models to integrate seamlessly into modern design pipelines.
BIM management
BIM management oversees the end-to-end implementation, coordination, and maintenance of Building Information Modeling across every stage of a project. By establishing clear standards and managing data streams across disciplines, it ensures digital models remain accurate, consistent, and fully aligned throughout the project lifecycle.
- Set & Enforce Standards: Establish consistent modeling protocols, data structures, and execution plans across all project teams.
- Streamline Discipline Coordination: Manage cross-team collaboration to resolve spatial conflicts and maintain alignment between design disciplines.
- Reduce Errors & Rework: Maintain data integrity throughout the project lifecycle to minimize field errors and costly change orders.
- Support Long-Term Operations: Deliver rich, structured digital assets that seamlessly transition from construction to ongoing facility management.
MEP Modeling
MEP modeling creates fully coordinated 3D digital representations of a building’s mechanical, electrical, and plumbing infrastructure within a single BIM environment. By mapping complex networks—including HVAC ductwork, electrical conduits, lighting, process piping, and fire protection—project teams can visualize spatial relationships and system interactions prior to site installation.
- Cross-Trade Coordination: Unify mechanical, electrical, and plumbing models into a central interface to align all engineering disciplines.
- Automated Clash Detection: Spot spatial overlaps between MEP systems and structural elements early to avoid costly field modifications.
- Prefabrication Support: Generate precise spool drawings and model data to enable off-site assembly and faster jobsite installation.
- Optimized System Performance: Ensure proper clearances for ongoing maintenance, accessibility, and long-term facility operations.
Fabrication Drawings
Fabrication drawings provide precise, shop-level manufacturing details that specify exactly how building components—such as ductwork, process piping, and structural steel—are fabricated and assembled off-site. Going beyond high-level design concepts, these drawings deliver exact dimensions, material specifications, joint connections, and assembly steps for shop fabricators and field installation crews.
- Drive Off-Site Prefabrication: Supply precise spool and shop drawings to enable high-efficiency off-site manufacturing.
- Ensure High-Precision Assembly: Provide clear connection details and exact measurements to guarantee components fit correctly during jobsite integration.
- Minimize Field Rework & Errors: Eliminate spatial ambiguities early to prevent costly on-site modifications, material waste, and installation delays.
- Streamline Field Execution: Deliver actionable, step-by-step assembly guides that help field crews install systems quickly and accurately.
Point Layout
Point layout transfers exact 3D design coordinates from digital BIM models directly onto the physical jobsite using robotic total stations and layout technology. By converting digital plans into precise real-world anchor points, field teams ensure structural, mechanical, and architectural elements are installed in exact alignment with the project design.
- Ensure High Precision Alignment: Transfer digital layout points directly to the field with millimeter accuracy for foundations, hangers, and sleeves.
- Eliminate Manual Measuring Errors: Replace traditional tape measures and manual string lines with automated optical tracking to avoid layout drift.
- Accelerate Field Installation: Speed up layout times on complex jobsites, allowing trade crews to begin installation faster with full spatial confidence.
- Maintain Design Intent Integrity: Verify that as-built physical placement matches initial BIM coordination models to prevent downstream trade clashes.
Project Takeoff
Project takeoff is the detailed process of quantifying materials, labor, and components from construction drawings or 3D BIM models to establish precise project scopes. By calculating exact lengths, surface areas, material volumes, and element counts—such as linear feet of piping, cubic yards of concrete, or fixture totals—takeoffs form the core foundation for accurate project estimating and procurement planning.
- Build Reliable Cost Estimates: Deliver precise material quantities to build tight, competitive bids and eliminate budget guesswork.
- Improve Procurement Planning: Identify exact material requirements upfront to optimize purchasing schedules and reduce jobsite material waste.
- Ensure Scope Completeness: Measure every design element across all disciplines to prevent unbudgeted surprises during active construction.
- Support Model-Based Estimating: Extract quantities directly from BIM models (5D BIM) for faster, automated, and highly accurate takeoffs.
Scan to BIM
Scan to BIM converts high-resolution laser scan data (point clouds) into accurate, intelligent 3D BIM models representing real-world as-built conditions. By translating raw physical scan geometry into rich digital components—such as structural framing, architectural elements, and complex MEP networks—project teams capture precise field environments without relying on legacy drawings.
- Optimize Renovations & Retrofits: Model complex existing conditions with precision to plan alterations without unexpected structural or MEP surprises.
- Reduce Field Verification Time: Minimize manual jobsite measurements and repeat site visits by referencing a complete, reliable digital double.
- Identify Existing As-Built Clashes: Overlay new design elements against current physical conditions to catch spatial conflicts before construction begins.
- Create Accurate Facility Records: Deliver high-fidelity digital models for long-term operations, maintenance planning, and future renovation cycles.
Point Cloud Processing
Point cloud processing is the workflow of cleaning, organizing, and refining raw 3D laser scan data to make it actionable for design and construction applications. This involves stitching together multiple setup scans (registration), filtering out environmental noise, aligning coordinate systems, and segmenting dataset elements. Processed point clouds establish the clean digital foundation required for downstream Scan to BIM modeling, spatial analysis, and site verification.
- Stitch Multi-Scan Datasets: Register independent setup scans into a single cohesive, geo-referenced spatial dataset.
- Eliminate Data Noise: Filter out transient objects, reflective artifacts, and environmental interference to ensure high-fidelity surface clarity.
- Accelerate Modeling Workflows: Prepare clean, lightweight point clouds that load efficiently in CAD and BIM authoring software.
- Verify Site Tolerances: Compare processed point clouds against design models to analyze spatial deviations and surface flatness.
