FAQ's

The time required for onsite work depends on the size and complexity of the site. Each project is unique, so we tailor our approach accordingly.
Yes, you can be present. Movement doesn’t interfere with the scanning process, but we recommend a relatively static environment to ensure the best results.
 

LiDAR (Light Detection and Ranging) uses laser pulses to map and measure the environment. Here’s how it works:

Laser Emission: LiDAR systems emit rapid laser pulses, usually in the near-infrared spectrum.


Reflection: The laser pulses bounce back after hitting objects or surfaces.


Distance Calculation: By measuring the time it takes for the pulses to return, LiDAR systems can calculate the precise distance to the surface.


Data Collection: LiDAR collects millions of data points per second, creating a detailed “point cloud” that represents the scanned environment.


Data Processing: This point cloud is processed to generate 3D models, detailed maps, and accurate measurements that can be used for a variety of applications, including surveying and environmental modeling.

We capture 360-degree reference photos to complement the scanning process. These images provide a visual reference that helps ensure accuracy during the drafting phase and allows us to revisit details later.

Turnaround time varies depending on the size and complexity of the site. We work efficiently to provide the best results within a reasonable timeframe.

  • Building Condition Assessment: To evaluate the structural integrity and identify areas in need of maintenance or repair.

  • Renovation or Restoration Projects: To obtain precise measurements of an existing structure before starting any renovations or restorations.

  • Building Design and Redesign: To analyze the current layout, helping architects and designers plan efficient and functional changes.

  • Compliance with Building Codes: To ensure the building meets current safety, accessibility, and zoning regulations.

  • Property Valuation and Due Diligence: To assess the building’s condition for real estate transactions, investment planning, or property leasing.

  • Sustainability and Energy Efficiency: To identify energy inefficiencies and plan for improvements or green building certifications (e.g., LEED).

  • Legal or Insurance Purposes: To provide accurate documentation for legal disputes, insurance claims, or property assessments.

  • Site Analysis for New Construction: To gather data on topography, existing utilities, and site conditions that affect new construction projects.

  • Historical and Cultural Significance: To document and preserve the features of historically significant buildings for restoration or preservation purposes.

  • Construction and Project Management: To provide a detailed reference for project planning, cost estimation, and coordination of trades.

  • Risk Management and Safety: To identify potential safety hazards, such as structural issues or compliance gaps that need to be addressed.

  • Documentation and Historical Record: To create a permanent, accurate record of the building or space for future reference or renovations.
    As-builts are essential for anyone needing precise, up-to-date information about an existing space to guide future design, construction, or maintenance decisions.
