Requirement

As a leading construction solution provider in New Zealand, POWERPAC offers a variety of facilities and  equipment to numerous construction sites. In addition to construction-related equipment, it also includes  entrance control and time attendance equipment. Generally, construction sites use various styles of access  control systems installed at their entrances. The site environment can vary greatly and is often harsher than that  of offices, with equipment exposed to dust and rain. For the access control system to function effectively, it must  meet certain specifications, which often increases costs. However, construction sites are inherently temporary;  once a project is completed, all equipment must be dismantled. As a supplier, POWERPAC seeks a more costeffective method that minimizes waste. POWERPAC's idea is to adopt a rental model akin to office copying  equipment, leasing access control and attendance equipment to contractors. This approach can lower costs for  contractor clients, making POWERPAC's services more attractive, while also allowing for equipment recovery,  thereby increasing return on investment. To achieve this goal, access control and attendance equipment must  be mobile and relocatable. A feasible method is to utilize containers, commonly used on construction sites as  temporary offices and storage rooms, taking advantage of their easy transport characteristics, making them ideal  for port installations at site entrances. To become an ideal entrance control and time & attendance management  system, it must possess various functionalities:

Precise Identity Authentication

Large construction sites often have a significant number of different workers entering and exiting, which poses challenges for attendance and security. The high volume of staff makes it difficult to ensure that the person clocking in is indeed themselves. Relying on security personnel for visual identification can easily lead to mistakes, resulting in issues such as buddy punching, which negatively affects human resource management efficiency. Moreover, failing to accurately identify entrants can create security loopholes, allowing unauthorized individuals easy access, leading to potential dangers or losses. Therefore, relevant regulations often require contractors to maintain accurate records of entries and exits. Thus, a reliable method for accurately identifying entrants is crucial for improving human resource efficiency, attendance management, security, and compliance with legal requirements.

Operational Efficiency

With a large number of employees entering and exiting daily, inefficiency in this process can severely disrupt construction operations. Thus, while ensuring precise identity verification, it is also essential to ensure that the system operates quickly and smoothly.

Adaptability to Harsh Environments

Unlike indoor office settings, construction sites are greatly influenced by weather conditions. Factors such as wind, rain, and even snow must be considered, and the cleanliness of the site is generally lower, with more dust and debris. Therefore, equipment used on construction sites must be more robust and durable to withstand harsh and variable environments.

Challenges

Wiring Difficulty

Security or attendance equipment cannot simply be installed in one place and considered operational. For proper functionality, equipment must connect to power and a transmission network. For fixed installations, this is not overly complicated. However, if the systems are installed in movable containers, every installation requires complex wiring, which can reduce installation efficiency and ultimately increase costs, contradicting the goal of cost-effectiveness and decreasing the attractiveness to potential customers.

Equipment Size and Container Capacity

The equipment required by POWERPAC needs to achieve high-strength access control to prevent illegal entry, including direct intrusion and tailgating. This often cannot be easily achieved with standard half-height turnstiles commonly found at railway stations. Full-height barriers are needed for comprehensive protection. However, the environmental differences at construction sites can be substantial, and not all sites have enough space to place a 20-foot container as an entrance. Therefore, some containers may not have openings on both ends but only at the front and back, allowing them to be positioned vertically as entrances. Some containers may even need to be reduced to 10 feet in length. Full-height turnstiles are large, making it difficult to fit them into relatively confined spaces.

Solution Details

ZKTeco’s Entrance Control  and Time & Attendance System Installed on Containers

ZKTeco provides a customized integrated entrance control and attendance system solution for customers, including the FHT2300D full-height turnstile and SpeedFace-M4 biometric authentication terminal, connected to the ZKBio CVSecurity comprehensive security management software platform for centralized management of entrance control and attendance.

The FHT2300D and SpeedFace M4 are not installed at  specific sites of POWERPAC's clients but are located  within containers owned by the clients, becoming a  movable entrance control and attendance system.

Biometric Authentication of Identity for Entrance Control and Attendance

POWERPAC places the entire container at the  construction site as the entrance. All employees  entering the site must pre-register their employee  and facial recognition data in ZKBio CVSecurity.  While employees are issued RFID staff cards, they  do not need to swipe cards for identification when  entering or exiting the site; they only need to scan  their faces at the SpeedFace M4, which will perform  facial recognition and matching. Upon verifying their  identity and permissions, they will be granted access.

Integration with Existing Human Resource Systems

Considering that POWERPAC already has an effective human resource management system, the most cost-effective approach is to integrate ZKBio CVSecurity with their existing MS SQL database via a direct link. This enables real-time transmission of attendance records to POWERPAC's MS SQL server, allowing human resource staff to obtain timely attendance data without manually collecting it from the attendance system.

FHT2300D Turnstile Customization

ZKTeco customizes the FHT2300D for different container sizes to fit each container's layout. For example, in a sufficiently spacious 20-foot container, the arm can be extended to create a wider passage while still preventing tailgating. In a narrower 10-foot container, overlapping sections of two FHT2300D units used for entry and exit can be shared, thereby reducing the space occupied by both sets of equipment inside the container.
