Construction sites are inherently dynamic environments. Deliveries, transport, and workflows must be constantly coordinated to ensure smooth operations. Yet, despite careful planning, delays are common. Materials arrive late, resources like cranes or elevators reach capacity, and logistical bottlenecks stall construction progress. BIM2LOG solves these issues by taking planning to the next level: the method combines digital modeling with precise time and logistics management to make construction processes fully controllable. Below, we present five classic construction site challenges and how BIM2LOG solves them.
1. Transport bottlenecks: BIM support for cranes and elevators
Using an algorithm, the BIM2LOG planning method provides exact parameters that, when combined with the right material (BIM), at the right time (LEAN), and in the right place (LOG), allow for the precise simulation of all construction site logistics. Even during the planning phase, the model accounts for material flows, storage areas, and transport routes, ensuring resources are available exactly when needed. This predictive planning identifies potential bottlenecks early, continuously optimizing the construction process and preventing delays. The result: production efficiency gains of up to 20 percent.
In practice:
On construction sites where materials are frequently transported vertically, the lift plays a key role as well. Bottlenecks often occur, especially when multiple trades need to use the same elevator simultaneously. Through real-time analysis of lift demand, BIM2LOG ensures that capacity is always aligned with actual demand, keeping operations running smoothly.
2. Inefficient resource utilization: 4D simulation optimizes scheduling
At the heart of BIM2LOG is 4D simulation, which goes beyond building geometry to integrate the temporal dimension. This allows construction processes to be precisely visualized and simulated, enabling the creation of accurate schedules, efficient resource use, and the implementation of the right measures. A just-in-time delivery strategy ensures that materials reach the site exactly when needed. This coordinated logistics management reduces process costs by up to 25 percent.
In practice:
BIM2LOG calculates quantity flows with precise timing. This also makes it easier to predict crane utilization. While the crane is essential on many construction sites, its use is often not optimally planned, leading to overloading or downtime. BIM2LOG better aligns crane requirements with overall material flow, ensuring optimal utilization.
3. Planning doesn't match reality: Better coordination through digital networking
The continuous collection of real-time data enables BIM2LOG to dynamically adjust logistics processes throughout the construction phase. Sensors and digital monitoring methods analyze and optimize all processes in real time. Dashboards visualize project status and present target and actual values transparently, so that all parties involved always have a clear view of the current construction status. Deviations can be identified and corrected immediately. The “Cadmium” software solution supports this process by controlling, analyzing, and visualizing all data processes.
Why plans and reality drift apart
A common reason for bottlenecks lies deeper than what is visible on the construction site: every trade works with its own models, nomenclature, and data versions. If these deviate from one another, quantities, schedules, and material flows no longer align, and an inconspicuous data inconsistency turns into a real traffic jam on-site. BIM2LOG therefore first checks model data for data density, maturity, and the degree of networking, creating a consistent foundation through standardized nomenclature before schedules and logistics are even planned.
In practice:
During the construction of the Claraturm in Basel, a high-rise nearly 100 meters tall with only a single access point, a digital twin precisely mapped the entire construction process in advance. This allowed the complex material flow to be simulated before it became reality: from the scheduling of up to 32 truck arrivals per day and elevator usage to the utilization of storage areas. The planning matched reality so accurately that bottlenecks never even occurred.
“The digital twin of the Claraturm was almost error-free and thus served as an important basis for decision-making.” — Diego Frey, Halter AG
4. Material congestion and rework: The pull principle as a solution
In the traditional push principle, materials are delivered in advance, leading to unnecessary storage and longer transport routes. BIM2LOG replaces this with the efficient pull principle, where materials are only requested when they are actually needed. This just-in-time delivery strategy reduces both storage costs and transport routes, ensuring that logistics processes are precisely aligned with construction progress. This precise control reduces material waste by up to 10 percent.
In practice:
The construction of the Roche pRED research center in Basel demonstrates how consistently the pull principle can be implemented. Located in a densely built-up area, there was no on-site storage space available—a logistical challenge. Consequently, material could only be delivered if it was to be installed immediately. Deliveries were bundled via an upstream consolidation center and brought to the construction site just-in-time. The result: direct deliveries to the site dropped by 40 percent, while up to 80 truck movements per day were handled centrally via the consolidation center.
5. If your construction plan is still analog: BIM2LOG also digitizes existing projects
BIM2LOG is suitable not only for new builds but also for existing projects and renovations. For projects without an existing BIM model, the method offers a 2D-to-3D generator, which automatically converts traditional building plans into digital models. This flexibility allows BIM2LOG to be used in a wide variety of projects and enables the integration of existing buildings into digital planning. This makes BIM2LOG ideal for both new construction and the renovation of older buildings.
Conclusion: BIM2LOG takes construction planning to a new dimension
BIM2LOG represents a new standard in construction management. By combining model-based logistics planning, 4D simulation, real-time control, and the pull principle, the method creates highly efficient, coordinated construction logistics. Transforming construction sites into networked, data-driven production environments is no longer a vision, but a living reality with measurable benefits: higher productivity, lower costs, and more sustainable processes. BIM2LOG is a true game changer for the construction industry.
