Construction Site Logistics Management · Engineering Logistics
Site Logistics Management (SLM) refers to the management activities of planning, organizing, coordinating, and controlling the entire process of materials at a construction project site and its surrounding areas—from arrival and receipt, on-site storage, secondary handling, and process-based distribution, through to waste removal and demobilization. It is distinct from macro-level supply chain logistics (which focuses on procurement, international shipping, and customs clearance), as it concentrates on the efficiency of physical flows in the "last mile" and even the "last hundred meters" at the site.
In the context of overseas EPC general contracting, site logistics management is typically led by the general contractor, coordinating subcontractors, suppliers, local transportation resources, warehousing teams, and construction crews to form a closed loop of "arrival—warehousing—requisition—distribution—demobilization."
The reason site logistics management for overseas projects has been singled out and increasingly standardized stems from the following practical pressures:
| Driving Factor | Specific Manifestation |
|---|---|
| Geographic and regulatory complexity | Multiple national ports, customs, and right-of-way restrictions; high volatility in material arrival times |
| Constrained site conditions | Limited space, unpaved roads, extreme weather; high difficulty in storage and handling |
| Numerous interfaces | Involvement of owners, supervisors, subcontractors, local communities, military/police security, and other parties |
| Cost sensitivity | On-site secondary handling and idle time often account for 20%–40% of total logistics costs |
| Safety and compliance | Hazardous chemicals, heavy equipment, and bonded materials must comply with local regulations |
| Digitalization trends | BIM, IoT, RFID, and GPS dispatch systems are progressively being deployed at site level |
As a result, an increasing number of overseas general contractors under central state-owned enterprises are separating site logistics management from the "construction organization design" to form a dedicated management plan.

The starting point of site logistics management is the Logistics General Layout. It must be designed in coordination with the construction general layout, temporary facility layout, and safety access routes.
List of core elements:
Key point: The logistics general layout is not drawn once and fixed; it should be dynamically adjusted according to construction phases (foundation phase, structural phase, installation phase, and commissioning phase each differ).
The "entry gate" of site logistics determines all subsequent efficiency. The following standard process is recommended:
| Step | Key Actions | Responsible Party |
|---|---|---|
| Arrival appointment | Supplier declares vehicle number, materials, and time 48h in advance | Supplier/Logistics Coordinator |
| Gate verification | Check PO, packing list, and seals | Security/Logistics |
| Unloading guidance | Guide to designated areas to avoid road blockage | Site Logistics Team |
| Unpacking inspection | Quantity, appearance, accompanying documents | QC/Warehouse Keeper |
| System entry | WMS/ERP entry, RFID tagging | Warehouse Keeper |
| Exception handling | Shortage, overage, damage, wrong delivery | Procurement/Supplier |
Common pain points: Concentrated arrival times causing unloading queues; discrepancies between documents and physical goods leading to vehicle detention fees; inconsistent acceptance standards causing repeated unpacking.
Overseas site warehousing is typically categorized as:
Inventory control should adopt ABC classification + safety stock + turnover rate monitoring:
Key indicators: inventory turnover rate, slow-moving material ratio, book-to-physical accuracy rate, requisition timeliness rate.
Secondary handling is a cost black hole in site logistics. Management essentials:
> Empirical data: Shifting from requisition to delivery can reduce crew waiting time by 15%–30% (varies by project).
Site logistics does not end at "entry." Reverse logistics includes:
Compliance reminder: If bonded materials or temporarily imported equipment are not demobilized or written off as required, customs penalties may be triggered. Continuous coordination with customs brokers is essential.

| Comparison Dimension | Chinese National/Industry Standards | International Standards (e.g., ISO Series, FIDIC-Related Clauses) | Local Standards |
|---|---|---|---|
| Focus | Construction organization, safe and civilized construction | Contractual logistics responsibilities, risk transfer | Customs, right-of-way, environmental protection, labor |
| Level of logistics detail | Mostly embedded in construction organization design | Contract and interface-oriented; limited site-level detail | Compliance and permitting-focused |
| Warehousing requirements | Clear zoning and fire protection provisions | Per contract and owner specifications | Strict requirements for hazardous chemicals and bonded warehouses |
| Document language | Primarily Chinese | Primarily English | Local language + English |
| Application recommendation | As internal management baseline | As contractual performance basis | Must be satisfied with priority |
> For specific standard numbers, please refer to official documents and contract technical annexes.
Integration approach: Use local regulations as the bottom line, international contracts as the framework, and Chinese national standards as internal operating procedures—applying all three in combination.

Materials for such projects are largely shipped from China to Karachi Port, then transported overland to the site. Site logistics must address: port congestion, inland transport security, on-site unloading queues, and multi-subcontractor requisition conflicts. Public reports indicate that such projects commonly adopt a three-tier system of "port forward warehouse + site central warehouse + subcontractor secondary warehouse."
Industrial park projects in Indonesia are often located in remote areas with poor road conditions and long rainy seasons. Site logistics priorities include: road maintenance, pre-positioning inventory for the rainy season, barge-to-truck transfer coordination, and local community relations. According to public reports, several industrial parks have adopted enclosed logistics dispatch and GPS vehicle monitoring.
Middle East projects generally require high-standard HSE and bonded warehousing. Site logistics must satisfy: high-temperature work windows, special permits for hazardous chemicals, joint acceptance by owner/supervisor, and bonded material write-off. Public reports show that such projects often establish dual-track management with an independent logistics contractor and the general contractor's logistics department.

Q1: Which department of the general contractor should lead site logistics management?
A: A common practice is for the construction department/project management office to lead, with procurement, warehousing, HSE, and customs brokers coordinating. Some central state-owned enterprises establish an independent "Logistics Department." The key is to designate a single accountable person.
Q2: If materials fail acceptance upon arrival, who bears the vehicle detention fee?
A: It depends on contract terms. Generally, if caused by the supplier, the supplier bears it; if caused by insufficient on-site unloading capacity, the general contractor bears it. It is recommended to specify this clearly in the procurement contract.
Q3: What are the most common problems in on-site management of bonded materials?
A: Book-to-physical discrepancies, overdue write-offs, and unauthorized use. Dedicated personnel and separate accounts are needed, with regular reconciliation against customs data.
Q4: How can on-site secondary handling costs be controlled?
A: The core is to reduce the number of handling operations. This is achieved through logistics general layout optimization, a delivery system, distribution kanban, and shared tools and equipment.
Q5: Are digital systems (WMS/RFID) worth deploying at overseas sites?
A: It depends on project scale and network conditions. Large multi-section projects yield obvious benefits; small projects can transition with Excel + QR codes first. Pay attention to local network and data compliance.

1. Draw the logistics general layout first, then the construction general layout—both must be reviewed jointly.
2. Establish a single logistics coordination window to avoid subcontractors acting independently and causing site congestion.
3. Implement a delivery system, gradually reducing crew self-requisition to minimize idle time.
4. ABC classification + cycle counting—focus limited manpower on high-value materials.
5. Dedicated warehouse, accounts, and personnel for bonded/hazardous materials, with monthly reconciliation with customs brokers.
6. Arrival appointment system—suppliers declare in advance to reduce vehicle detention and queuing.
7. Plan reverse logistics in advance—establish processes for demobilization, waste, and write-off at the project's early stage.
8. Indicator-based management: inventory turnover rate, book-to-physical accuracy rate, distribution timeliness rate, and vehicle detention duration—review monthly.
> The above recommendations are common industry practices. For specific implementation, please combine with project contracts, host country regulations, and owner specifications.
