RFID in Construction: What You Need to Know

Rfid In Construction 1

How does RFID work in construction?

Radiofrequency identification (RFID) technology is used in the construction industry to improve safety, increase efficiency, and as an asset tracking software. RFID systems consist of a reader or interrogator that emits a signal to labels or tags. The tags contain a microchip to store and process information and an antenna that receives and transmits a signal to the reader. In passive systems, when the reader emits electromagnetic waves, it powers the tag, which transmits the data back to the reader.

RFID technology is used in construction for equipment and tool management, inventory management, workforce management, and enhancing safety. It can track thousands of high-value assets used at construction sites, reducing the need to order or rent new items as replacements for equipment that cannot be located. RFID solutions are an easy way of keeping track of which tools have been checked out, which employee checked them out, as well as how long the tool was used once it is checked back in.

The Cons 
1. High cost of equipment
Implementing RFID technology requires expensive equipment, such as RFID readers, antennas, and tags. These costs can impact project budgets, especially for larger construction projects.
2. Lack of standardization
The lack of standardization in RFID technology for construction can lead to integration challenges and increased costs. Different systems may require various hardware and software.
3. Lack of widespread adoption
The construction industry has limited adoption of RFID technology due to challenges in implementation, management support, strategy, funding, and planning.
4. Poor infrastructure
Poor infrastructure can affect RFID data collection and transmission, leading to incomplete or inaccurate data on remote job sites.
5. Inconvenience for workers
RFID technology may cause inconvenience for workers, including additional scanning steps, training, and a perception of added burden.
6. Technical complications
Technical challenges with RFID include signal interference, power limitations, and integration issues with legacy systems.
7. Security and privacy concerns
RFID tags can be vulnerable to unauthorized access and data breaches, raising security and privacy concerns, particularly in less secure construction environments.
8. Lack of ROI
High implementation costs and limited benefits may not provide a sufficient return on investment, especially for smaller construction companies.
9. Unsuitable for all types of projects
RFID may not be suitable for projects with a small number of materials, frequent material changes, or materials that are not easily tagged.

What to look for in an RFID tool and equipment tracking software?

1. A database to keep track of inventory items

A database is a crucial component of an RFID tool and equipment tracking software. It stores all the information related to each asset, including its location, status, and maintenance history. The database should be designed to be easily searchable and updateable, allowing for real-time tracking of assets. It should also be customizable, allowing businesses to create asset fields that are relevant to their specific needs.

For example, a construction company may want to track the voltage of a piece of equipment, while an IT asset manager may want to track the serial number of a laptop. The database should also be secure, with access controls in place to prevent unauthorized changes to asset information.

2. Ability to track objects in real time

RFID tags emit a signal that is picked up by RFID readers, which then transmit the location and status data to a cloud-based system. This system updates in real-time, allowing for accurate and up-to-date information on asset location and status.

This feature can benefit construction sites in a number of ways. For example, it can reduce on-site loss and theft by enabling centralized records that incorporate location and status data. It can also improve safety practices and decrease materials-related incidents with contact tracing software that tracks crew whereabouts and potentially hazardous situations.

3. Integration with other systems

The RFID tool and equipment tracking software can integrate with other systems in construction, including building information modeling (BIM) and cloud-based systems. This integration allows for real-time updates and information retrieval, reducing on-site loss and theft while enabling centralized records that incorporate location and status data. The benefits of integration include increased efficiency, improved asset management, and reduced costs.

For instance, a BIM-based cyber-physical system can be used for the automated monitoring of buildings during their regular operation, generating information that is then used to update the digital model and support facility managers in making decisions.

4. Ability to track items at all stages of the construction process

The RFID tool and equipment tracking software can provide construction professionals with a comprehensive solution to track items at all stages of the construction process. From the moment items are received on the job site until they are returned to the warehouse, RFID technology can help manage the status and location of each item.

5. Ability to track items across multiple locations

RFID tool and equipment tracking software is a powerful tool that helps construction companies keep track of their assets across multiple locations. Here’s how it works:

Real-time tracking

  • RFID technology enables real-time tracking of tools and equipment, allowing users to see their location and status at any given time.
  • This means that if a tool is moved from one location to another, the system will update automatically, giving users the most up-to-date information possible.

Centralized records

  • RFID tracking software enables centralized records that incorporate location and status data, making it easy to keep track of tools and equipment across multiple locations.
  • This means that if a tool is checked out from one location and moved to another, the system will update automatically, giving users a complete record of its movements.

6. Ability to track items with different types of RFID tags

There are different types of RFID tags available, each with its own benefits and drawbacks. In this explanation, we will discuss the importance of being able to track items with different types of RFID tags in construction tools and equipment tracking software, provide examples of these different types of tags, and suggest a writing structure that includes an introduction, detailed explanation, and conclusion.

Different types of RFID tags have varying capabilities and are suited for different tracking purposes. Passive RFID tags, for example, do not have a built-in power supply and only become active when in the presence of an RFID reader. These tags are less expensive and can be used for tracking items with short-range distances. Active RFID tags, on the other hand, have a built-in power supply, are active all the time, and can be used for tracking items with longer-range distances.

7. Ability to track items with different types of RFID readers

A tool and equipment tracking software’s ability to track items with different types of RFID readers is crucial in construction. It allows for the efficient and accurate tracking of materials, workers, and equipment, leading to better project management and cost savings. Here are some examples of different types of RFID readers and how they can be used in construction:

  1. SmartX HUB Mobile RFID reader: This reader can be used by an auditor or authorized staff to find specific sets of assets that are reported as missing from previous audits or counts. It ignores all other tags, making it easier to locate missing items.
  2. Automated readers mounted in facilities exit or entry doors: These readers can track assets with great read speed, with up to 400 items identified per second when moved in both directions. This makes it easier to monitor the movement of materials and equipment in and out of the construction site.
  3. Different readers attached to different locations: This approach allows for the tracking of materials in multiple storage sites. By typing in the information about the item, the exact location of the item can be revealed because it was scanned and keyed in.
