The Dynamic Weighing System for Construction Sites – Low Speed WIM

Logistics Management of Large Construction Sites: Safety and Control H24 with BISON low speed Dynamic Weighing

The logistical management of a large, multi-year construction site – such as those for the construction of maxi-infrastructures, tunnels, dams or major roadways – poses a complex challenge. Every day, hundreds of trucks enter and leave carrying earth, aggregates and materials of high commercial value.

In operational settings of this scale, monitoring transits with traditional static weighing methods means slowing down work, employing a lot of dedicated staff and leaving room for possible shortages.

To meet the safety, efficiency and cost-cutting needs of construction companies, iWIM has developed BISON LS Control (Low Speed Control), the innovative dynamic weighing system (Weigh-In-Motion) designed to revolutionize access control at large construction sites.

The Weigh-In-Motion (Weigh-In-Motion) Revolution.

The LS Control model makes it possible to weigh trucks and heavy vehicles in motion (up to 20 km/h), eliminating the queues and waiting times typical of traditional weighbridges. Installed at access gates, the system instantaneously records vehicle weight (total and single axle), speed and number of axles, ensuring a continuous and uninterrupted logistics flow.

Why is BISON WIM for low speed Control the ideal alternative to the weighbridge for large infrastructure works? Here are the strategic advantages.

  1. Total control of incoming and outgoing vehicles, H24

Large construction sites almost never stop. BISON LS Control is designed to run completely autonomously 24/7. Whether it is dawn, midnight or a public holiday, every single vehicle that crosses the threshold of the construction site is weighed and recorded in real time. This ensures absolute traceability of material flows, optimizing both incoming and outgoing yard management.

  1. Immediate cost reduction and software integration

A traditional truck scale requires the constant presence of personnel in the garret to record loads, validate transport documents, and manage access. In an active H24 construction site, this translates into high shift costs.

Being a fully automated weighing system, LS Control does the job autonomously. The data recorded at each transit are transmitted directly to the customer’s servers-they can be easily integrated into existing information systems, enabling simplified information management.

This is a crucial advantage in achieving rapid integration without the need for costly customization. This allows staff to be redeployed to more productive tasks and to achieve drastic savings in operating costs.

  1. Material theft prevention and maximum security

When handling huge quantities of aggregates and raw materials for years, the risk of theft, unauthorized dumping, or discrepancies on loads is high.

With the BISON LS Control system you have the mathematical certainty Of what goes in and what comes out. By integrating the weighing system with ANPR cameras (for automatic license plate reading) and context cameras, each transit is photographed and associated with its exact weight. This automation eliminates human error and serves as a powerful deterrent against theft.

The power of Bisonte technology: extreme efficiency for construction sites

In addition to its management advantages, the system is distinguished by the unique technical features of the BISON family, which are perfect for heavy-duty, ever-changing work environments such as large construction sites:

  • Exceptional durability and minimal maintenance: The system is constructed of austenitic stainless steel, designed to withstand even the harshest conditions. With no moving mechanical components, maintenance is kept to a minimum.
  • Invulnerable fiber optic sensors: The system is immune to temperature variations that usually plague electronic systems. Snow and mud do not affect the performance of the Bisonte system, which remains stable and reliable in all weather conditions. In addition, the use of optical fiber confers high immunity to electromagnetic fields.
  • Safety without compromise: Bisonte is free of electrical cables or electronic devices under the plates, eliminating any risk of electrocution.
  • Long-distance communication: The system uses fiber optics to transmit data up to a distance of 10 km without the need for signal regeneration. This allows the datalogger to be installed even in locations remote from the measurement site.
  • Long-term calibration: The need for Bisonte system calibration is required only every 4-5 years, providing significant cost savings and business continuity.
  • Maximum flexibility in installation and asphalting: The system can be installed on existing roads without the need for resurfacing, even on surfaces with an International Regularity Index (IRI) of up to 4 mm/m. In addition, a unique advantage of the Bisonte system is the possibility of resurfacing without removing the weighing plates.
  • Rapid relocation and repositioning: The Bisonte system is designed to be easily repositioned. If necessary, the plates can be moved to a new installation site, proving to be a versatile solution that is perfectly suited to the needs of expansions or future construction sites.

In infrastructure projects that last for years, logistical efficiency makes a difference on the final profit margin. Relying on the BISON LS Control dynamic weighing system means choosing an advanced technology that pays for itself over time, cutting unnecessary costs, zeroing out queues at the gates, simplifying maintenance and armoring the construction site against material shortages.
