Shandong YunCang Cold Chain Park Project

The park comprises 8 independent cold storage units with a total floor area of approximately 320,000 m². This scale requires systematic coordination of structural schemes, phased construction organization, and delivery schedule management across multiple large cold stores, rather than simply replicating single-store experience. BICP was engaged to provide post-tensioned structural technical services for all 8 cold stores, centered on the Taiku long-span post-tensioned flat slab system, to systematically advance the construction of this large-scale cold storage cluster.

Unified standards with individual optimization. For the 8 cold stores of varying sizes and functions, BICP adopted a strategy of 'unified design standards, targeted optimization per building.' All cold stores use the same long-span post-tensioned flat slab technology, with uniform anchorage system specifications, concrete strength grades, and tendon specifications, reducing procurement complexity and quality control difficulty while facilitating future maintenance. At the individual level, designs were differentiated based on specific functional requirements (temperature zones, rack types, load standards) to ensure precise alignment with usage scenarios. Comprehensive 3D finite element analysis was performed for each cold store using imported software, combined with BICP's proprietary optimization algorithm to determine tendon layouts, ensuring calculation accuracy and optimization across the entire park. Construction organization for such a large cold storage cluster posed significant challenges: resource allocation required staggered scheduling of post-tensioning activities to avoid conflicts; quality control involved a park-level management system with dedicated technical supervisors for each store, centralized data collection for tensioning records and elongation measurements, and anomaly alerts; schedule coordination was maintained through continuous collaboration with the general contractor, dynamically adjusting construction plans to meet key milestones.

Project Background

Linyi is a major agricultural product distribution and logistics hub in China, with significant cold chain logistics demand. Leveraging this geographical advantage, Shandong YunCang Cold Chain Co., Ltd. planned a large-scale integrated cold chain park to serve agricultural product cold chain circulation, food refrigeration and distribution, and other businesses.

The park comprises 8 independent cold storage units with a total floor area of approximately 320,000 m². This scale requires systematic coordination of structural schemes, phased construction organization, and delivery schedule management across multiple large cold stores, rather than simply replicating single-store experience.

BICP was engaged to provide post-tensioned structural technical services for all 8 cold stores, centered on the Taiku long-span post-tensioned flat slab system, to systematically advance the construction of this large-scale cold storage cluster.

Technical Solution

Unified standards with individual optimization. For the 8 cold stores of varying sizes and functions, BICP adopted a strategy of 'unified design standards, targeted optimization per building.' All cold stores use the same long-span post-tensioned flat slab technology, with uniform anchorage system specifications, concrete strength grades, and tendon specifications, reducing procurement complexity and quality control difficulty while facilitating future maintenance.

At the individual level, designs were differentiated based on specific functional requirements (temperature zones, rack types, load standards) to ensure precise alignment with usage scenarios.

Comprehensive 3D finite element analysis. BICP performed detailed finite element analysis for each cold store using imported software, combined with its proprietary optimization algorithm to determine tendon layouts, ensuring calculation accuracy and optimization across the entire park.

Construction Organization

Concurrent construction of a large cold storage cluster posed significant challenges:

• Resource allocation: Multiple simultaneous stores required concentrated post-tensioning crews and equipment, necessitating staggered scheduling to avoid conflicts.
• Quality control: BICP established a park-level quality management system, with dedicated technical supervisors for each store, centralized data collection for tensioning records and elongation measurements, and anomaly alerts.
• Schedule coordination: BICP's project management team maintained continuous collaboration with the general contractor, dynamically adjusting construction plans to meet key milestones.

Delivered Value

Through 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.

Reference Significance

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.
