Engineering by BICP
Design analysis for large industrial floors under heavy loads, forklift traffic, AGV operations and demanding service conditions.
What we solve
Most industrial floor failures are joint and crack failures. Each card below opens the engineering behind the problem and the design questions that decide the outcome.
Closely spaced contraction joints multiply the places where a floor can spall, curl and ravel. Jointless design starts by asking how many joints the slab really needs.
Read the engineering →Hard-wheeled forklifts hammer unprotected joint edges until the arris breaks down. Load transfer and edge protection decide how long a joint survives.
Read the engineering →Shrinkage, restraint and thermal movement drive random cracking in large panels. Reinforcement strategy and post-tensioning options change the outcome.
Read the engineering →Automated vehicles register every joint and step as a disturbance. Joint spacing, joint detail and flatness have to be designed for the fleet, not for the concrete.
Read the engineering →Rack post loads, wheel loads and their spacing govern slab thickness and the demand on the subgrade. Load cases must come from the real racking and equipment layout.
Read the engineering →Freezer floors move with every temperature cycle and sit on insulation with a different stiffness. Thermal effects change joint design, curing and detailing at doors and thresholds.

Engineering is the first service BICP provides on any international project. It is scoped and delivered independently of any product supply.
Feasibility, concept or early design, before the floor is fixed by the structural package.
Concept to detailed design, in coordination with the local design team and the engineer of record.
Whenever the slab system itself is still open: new build, extension or replacement floor.
Detailed design and pre-construction, once the joint layout is agreed.
Applications
The same joint and crack problems take different forms in different buildings. Each application page sets out the risks, the loads, what a jointless design must analyse and where joints still remain.

Clients come to BICP with a floor problem. BICP analyses the floor and settles the design route. Where construction or functional joints must remain, they are designed properly, and where an armoured joint is justified it is manufactured and supplied by SHENTE.
Projects
Selected projects that show the floor conditions BICP has worked with: large areas, joint reduction, heavy loads, forklift traffic, cold storage and automated logistics.
Post-completion, under the -60°C operating environment, the post-tensioned structure and BICP-ST anchorage system have maintained stable performance through subsequent periodic inspections. The large-span column layout effectively reduces internal columns, improving racking layout for national reserve goods and enhancing warehouse management efficiency. This project is a representative engineering practice for BICP in -60°C ultra-low temperature cold storage, validating the applicability of the BICP-ST anchorage system under such conditions and providing a reference for similar ultra-low temperature storage projects (e.g., aquatic product cold storage, specialty food storage) during anchorage system selection.
View project →Cold StorageUpon completion, the owner compared Phase II (B4, B5) with Phase I. The 12 m × 10 m large-span scheme reduced the number of internal columns by over 60% for the same floor area, increased usable storage volume by approximately 40%, and significantly improved rack layout flexibility and forklift maneuverability. Compared to traditional waffle slab systems, the structural depth of each floor was significantly reduced, lowering the effective refrigerated volume and positively impacting operational energy consumption. The project received the First Prize for Scientific and Technological Progress from the China Federation of Logistics & Purchasing and the Sichuan Civil Engineering Li Bing Award, recognizing its engineering value. This project is a representative early application of BICP's Taiku system in cold chain warehouses, validating the feasibility of large-span post-tensioned flat slabs for cold storage structures and providing a reference for structural selection in similar future projects. For investors evaluating large-span schemes during planning, refer to the 'Cold Storage Structural Scheme Preliminary Parameter Comparison' or contact BICP's technical team for preliminary consultation.
View project →Cold StorageThe large-span post-tensioned flat slab system effectively reduced the number of internal columns on each floor, improving rack layout flexibility for multiple temperature zones and enhancing warehouse management efficiency. The floor height advantage of the post-tensioned flat slab system, compounded across 12 stories, positively impacted overall building height and volumetric efficiency. This project represents a benchmark engineering practice by BICP in high-rise cold chain buildings (12 stories, 68.1 m), validating the applicability of large-span post-tensioned flat slab systems in managing cumulative vertical loads, coordinating inter-story drift, and ensuring long-term prestress performance. It provides a valuable engineering reference for structural system selection in similar high-rise cold chain storage projects.
View project →Cold StorageUpon project completion, the 12.7m large column spacing scheme reduced the number of internal columns while providing ample structural space for flexible arrangement of intelligent racking and automated equipment, improving effective storage capacity utilization and rack layout flexibility, meeting the owner's operational requirements for high-standard modern cold chain facilities. This project is a representative engineering practice of BICP's Taiku system in the Beijing market and a reference case for the application of large-span post-tensioned cold storage in urban logistics hub scenarios. It demonstrates the methodology of deep integration between rack system BIM collaborative design and structural system selection, as well as the technical review pathway for special structures under strict urban approval environments, making it suitable for reference by cold chain construction investors in Beijing and similar first-tier cities.
View project →Cold StorageThrough systematic execution, the cold storage cluster completed structural construction and acceptance in phases. The long-span post-tensioned flat slab solution reduced column count and increased effective storage capacity in each store, achieving the planned overall storage density. The uniform structural standards across all 8 stores also simplified later maintenance: maintenance personnel gained better understanding of structural characteristics and requirements, improving efficiency in troubleshooting and handling potential issues. This project demonstrates BICP's systematic delivery capability for large-scale cold chain parks. The methodology of 'park-level unified technical standards plus individual optimization' provides a reference logic for structural selection and construction organization of multi-store cold chain parks, suitable for investors and general contractors of large cold chain facilities.

Large warehouse floors crack mainly because drying shrinkage and temperature movement are restrained by the subgrade, by reinforcement, or by the slab's own geometry. Crack control comes from managing that restraint through panel size, reinforcement or post-tensioning, and curing, not from the concrete mix alone.
Read the answer →25 September 2026A jointless industrial floor is built as large reinforced or post-tensioned panels with construction joints only, instead of the tight grid of saw-cut joints used in conventional slabs. It suits large, heavily trafficked floors where joint maintenance, not the concrete itself, is the main source of downtime.

Read the answer →13 May 2026For the same post-tensioned cold storage warehouse, using the equivalent frame method versus 3D finite element analysis can result in a 15% or more difference in steel and concrete quantities. This article details the three limitations of the equivalent frame method (ignoring bidirectional interaction, averaging stress concentrations, and lacking global PT optimization) and the precision advantages of 3D FEA combined with BICP's proprietary PT optimization algorithm. It also explains the engineering validation behind the two core data points: "15% cost savings and 3x efficiency improvement."
