3D Laser Scanning: Rent, Buy, or Hire? A Comprehensive Guide for Architects and Engineers

3D laser scanning is revolutionizing the way architects and engineers document and assess existing conditions of buildings and sites.

By capturing millions of surface points, a laser scanner generates a high-resolution, geometrically precise point cloud, which provides an accurate and detailed representation of a site. This data is invaluable for many architectural and engineering projects, as it facilitates detailed planning, reduces errors, and improves efficiency. The question that often arises is whether to rent laser scanning equipment, purchase it, or hire a professional 3D laser scanning service. This guide will examine each option in detail, focusing on the needs of architects and engineers.

The Importance of 3D Laser Scanning in Architecture and Engineering

3D laser scanning has become a critical tool for architects and engineers working on diverse project types. It is particularly beneficial for documenting complex existing structures, creating accurate as-built models, and providing detailed information for renovations, retrofits, and new construction. Laser scanning data can be processed into 2D CAD drawings, 3D Building Information Modeling (BIM) models, or other customized deliverables depending on the project’s requirements.

The benefits of 3D laser scanning extend to various sectors, including:

• Architecture: Capturing detailed spatial data for design, renovation, and project planning.
• Engineering: Assisting in structural analysis, prefabrication, and facility modifications.
• Construction: Supporting construction sequencing, progress tracking, and accurate cost estimation.
• Asset Management: Providing detailed records for maintenance, repair, and future modifications.

While the advantages of 3D laser scanning are clear, choosing the right method of access—renting, buying, or hiring a professional service—depends on the specific needs and capabilities of the firm.

Common 3D Laser Scanning Equipment

Option 1: Renting 3D Laser Scanning Equipment

Renting laser scanning equipment can be a viable option for firms that need access to high-quality scanning technology on a temporary or occasional basis. Renting gives flexibility without the long-term commitment or the high initial cost of purchasing equipment.

Key Considerations for Renting:

1. Product Knowledge: Architects and engineers must ensure they rent the right equipment with the correct range and accuracy for their specific project needs.
2. Training: Effective use of laser scanning technology requires training. While basic operation may seem straightforward, understanding the nuances of scanning, data registration, and creating usable deliverables requires expertise.
3. Additional Costs: Rental agreements often come with extra costs, such as for targets, tripods, batteries, and software licenses. Additionally, many rental companies require proof of insurance and pre-approved accounts.

While renting eliminates the responsibility of servicing and maintaining the equipment, it is essential to factor in the time spent on training and data processing. Without the necessary expertise in-house, firms may find it challenging to convert raw point cloud data into actionable deliverables like CAD drawings or BIM models.

Costs of Renting 3D Laser Scanning Equipment:

• Daily: $743
• Weekly: $3,046
• Monthly: $9,188

Renting is an option for firms who want to test the technology before making a significant investment. However, unless the operator of the scanner is properly trained, the results may be unreliable.

Option 2: Purchasing 3D Laser Scanning Equipment

For firms with a continuous need for 3D laser scanning, purchasing equipment may seem like the best long-term solution. However, there is again the element of training and experience relative to accuracy, and this path also comes with significant upfront costs and ongoing operational expenses.

Key Considerations for Purchasing:

1. Capital Investment: High-end laser scanners can be expensive, with prices ranging from $18,000 for a basic model to over $85,000 for advanced systems.
2. Training and Expertise: Mastering 3D laser scanning is not a simple task. Firms will need to invest in both equipment and the training necessary to use it effectively. Additionally, ongoing software and hardware upgrades will be necessary to keep up with industry standards.
3. Data Processing: Scanning is just the first step. Architects and engineers must be able to register the point cloud data and convert it into useful deliverables like CAD files or BIM models. This may require additional resources, such as specialized software and skilled personnel.

Costs of Purchasing 3D Laser Scanning Equipment:

• Leica BLK360: $18,000
• Leica RTC360: $85,000
• Leica P40 ScanStation: $85,000
  
  

Option 3: Hiring a 3D Laser Scanning Service

For many architects and engineers, hiring a professional 3D laser scanning service offers the most efficient and cost-effective solution. This option provides access to experts with the latest equipment and software, allowing firms to focus on core design and engineering tasks without worrying about the intricacies of laser scanning technology.

Advantages of Hiring a 3D Laser Scanning Service:

1. Accuracy and Expertise: Professional scanning teams, like those at Existing Conditions, are well-versed in the latest technology and can provide fast, accurate field documentation. They can handle all aspects of scanning, from data capture to delivering highly detailed point clouds, CAD drawings, and 3D models.
2. Cost and Time Efficiency: Outsourcing the scanning process allows firms to reduce labor hours, minimize the risk of errors, and keep projects on track. The service provider takes responsibility for equipment maintenance, data registration, and creating the necessary deliverables.
3. Tailored Solutions: Experienced 3D laser scanning companies can customize their services based on the project’s needs, whether it requires night or weekend scanning, specific deliverables, or a fast turnaround.

Cost of Hiring a 3D Laser Scanning Service:

The cost of hiring a laser scanning service varies depending on factors such as the size and complexity of the site, the level of detail required in the deliverables, and the project timeline. Services typically provide detailed pricing based on the specific scope of work, including considerations like square footage, site access, and deliverable requirements.

Hiring a service like Existing Conditions ensures that architects and engineers receive high-quality data without needing to invest in costly equipment or training. Existing Conditions specializes in delivering accurate and reliable laser scanning data, providing architects and engineers with precise documentation to support their projects.

The Decision: Rent, Buy, or Hire?

When deciding whether to rent, buy, or hire a 3D laser scanning service, architects and engineers should consider several factors:

• Frequency of Use: How often will the technology be required?
• In-House Expertise: Does the firm have staff capable of managing the entire scanning process, from data capture to deliverable creation? If not, hiring a service may be the best option.
• Budget: What are the firm’s capital and operational budgets? Can it afford the high upfront cost of purchasing equipment and software, or does hiring a service offer better cost control?

Ultimately, hiring a professional 3D laser scanning service like Existing Conditions offers architects and engineers the most streamlined, efficient, and reliable solution. By working with experienced professionals, firms can ensure that they receive the precise, high-quality data needed for accurate design and project execution, without the added burden of managing equipment, training, and data processing themselves.
