CHEC Port Construction Specifications · Central SOE Standards
CHEC Port Construction Standards (hereinafter referred to as "CHEC Standards") is a corporate-level technical standards and management specification system gradually developed by China Harbour Engineering Company Ltd. (CHEC) through decades of overseas port engineering EPC practice. It is not a single document, but rather a collective term for a series of internal standards, construction method guidelines, and operating procedures covering the entire lifecycle of port planning, survey and design, construction and build, quality acceptance, and operation and maintenance management. In nature, CHEC Standards qualify as corporate standards, yet a large number of their clauses directly reference or equivalently adopt Chinese national standards (GB) and industry standards (JTS), with adaptive adjustments made in overseas projects according to host-country conditions.
The rationale for their development can be understood from three perspectives:
First, the unique challenges of overseas port construction. Overseas projects face complex situations including highly variable hydrological and geological conditions, incomplete material supply chains, unfamiliarity with local standards systems, and owners' consultants often adopting Anglo-American standards. CHEC accumulated extensive adaptive experience through projects such as the Gwadar Port in Pakistan, the Hambantota Port in Sri Lanka, and the Lekki Deep Sea Port in Nigeria, creating an urgent need to systematize this experience.
Second, the impetus from the Belt and Road Initiative. As infrastructure connectivity projects increased, ports—as key nodes—saw their construction quality directly linked to national image and corporate reputation. Against this backdrop, CHEC Standards accelerated integration, forming a replicable and scalable technical management template.
Third, the inherent demand for Chinese standards to "go global." CHEC Standards serve as a bridge for exporting Chinese port engineering technical standards overseas. While respecting local regulations, they adopt mature Chinese technical solutions wherever possible to reduce communication costs and construction risks.
In terms of scope of application, CHEC Standards primarily apply to overseas port projects where CHEC serves as the EPC general contractor or construction general contractor, covering typical engineering types such as gravity quay walls, piled wharves, breakwaters, channel dredging, yard roads, and port area ancillary facilities. For domestic projects or sections of joint-venture projects where the owner designates other standards, tailoring or conversion is required per contract terms.
At the design level, CHEC Standards use the Chinese industry standard *Code for Design of Port and Waterway Engineering* (JTS series) as the core reference, but require the design team to complete a local condition adaptability assessment. The core logic is as follows:
| Design Element | Chinese Standard Reference | Overseas Adaptation Points |
|---|---|---|
| Hydrology & Meteorology | JTS 145 series | Must use local measured data or authoritative institution data; return periods must be confirmed with the owner |
| Geological Survey | JTS 147 series | Survey depth and density must meet international consultant review requirements |
| Structural Design | JTS 167 series | Load combinations must account for local seismic and wind requirements; recheck per Anglo-American standards when necessary |
| Material Specifications | GB/JTS material standards | Locally procured materials require equivalence assessment; rebar, cement, etc. must comply with mandatory certification of the host country |
At the construction level, CHEC Standards emphasize a dual-track approach of "process standardization + on-site adaptation." Typical construction methods include:
For quality control, the standards require establishing a three-tier inspection system: crew self-inspection, project department re-inspection, and company spot checks, along with third-party testing agencies for verification of key indicators. For projects where the owner designates Anglo-American standards, corresponding ITP (Inspection and Test Plan) requirements must also be satisfied.
Overseas project material management is a key chapter of CHEC Standards. Core requirements include:
1. Local procurement priority: Subject to meeting technical requirements, prioritize local materials to reduce costs and shorten schedules.
2. Equivalence substitution assessment: When local material standards differ from Chinese standards, comparative tests on mechanical properties and durability must be conducted, and an assessment report submitted to the owner for approval.
3. Key equipment control: Large crane vessels, pile driving vessels, concrete batching plants, and other equipment must have established ledgers, regular calibration, and certified operators.
4. Logistics and warehousing: Given the long overseas supply chains, the standards require establishing safety stock for critical materials and developing contingency plans.
CHEC Standards place HSE (Health, Safety, and Environment) management on par with engineering quality. Main requirements:
| Dimension | Core Requirements |
|---|---|
| Safety Management | Establish project-level HSE system, conduct hazard identification and tiered control, develop special plans for work at height, over water, and lifting operations |
| Environmental Management | Dredged spoil disposal must comply with local environmental regulations; environmental impact assessments required for ecologically sensitive marine areas |
| Community Management | Respect local cultural customs, prioritize local labor employment, establish community communication mechanisms |
| Emergency Management | Develop special emergency plans for typhoons, tsunamis, oil spills, etc., with regular drills |
The standards require acceptance at three levels: sub-item works acceptance, sub-divisional works acceptance, and unit works acceptance, ultimately forming a completion documentation package for handover to the owner. For overseas projects, additional considerations include:
| Comparison Dimension | CHEC Standards | Chinese National Standards (GB/JTS) | International Standards (e.g., BS, ASTM, PIANC) | Local Standards |
|---|---|---|---|---|
| Nature | Corporate standards system | National/industry mandatory or recommended | International general reference | Host country mandatory regulations |
| Scope of Application | CHEC overseas projects | Projects within China | Globally applicable | Within host country |
| Technical Maturity | Based on Chinese standards + overseas adaptation | Mature and comprehensive | Mature and comprehensive | Varies widely |
| Owner Acceptance | Requires communication and confirmation | Requires conversion for overseas projects | Widely accepted | Must be complied with |
| Usage Strategy | Chinese standards as the core, flexible adaptation | As technical basis | As cross-reference and supplement | As compliance baseline |
In practice, CHEC Standards typically adopt a hybrid strategy of "Chinese standards as the primary framework, international standards as cross-reference, and local standards as the compliance floor," with the specific proportion depending on contract terms and owner consultant requirements.
Scenario 1: Gwadar Port Expansion Project in Pakistan. This port is located along the Arabian Sea coast, with complex hydrological and geological conditions, and is situated in a sensitive area. CHEC adopted a combined gravity quay wall and breakwater solution during construction, facing high-temperature and high-salt-spray corrosive environments. Public reports indicate that the project conducted specialized research on material anti-corrosion and concrete mix design, demonstrating CHEC Standards' adaptability in extreme environments.
Scenario 2: Hambantota Port Project in Sri Lanka. This project was built in multiple phases, involving large caisson precasting and installation, channel dredging, and other works. CHEC adopted Chinese-standard caisson precasting techniques while adjusting armor unit design based on local wave conditions. Public information indicates that the project has become an important transshipment port in South Asia, validating the feasibility of CHEC Standards in deep-water port construction.
Scenario 3: Lekki Deep Sea Port Project in Nigeria. CHEC participated in the construction of this project, which is the first deep sea port in West Africa. The project faced challenges including soft ground foundations and long-period swells, with CHEC Standards providing technical support in soft ground treatment and pile foundation design. Public reports indicate that the project has been put into operation and has become one of the landmark projects of China-Africa cooperation.

Q1: Do CHEC Standards have legal effect?
A: CHEC Standards are internal corporate standards and do not have direct legal effect. However, in projects where CHEC serves as the general contractor, they are transformed into binding obligations on subcontractors and suppliers through contract clauses. Meanwhile, the Chinese national standards and local regulations referenced in the standards each carry their respective legal status.
Q2: What if an overseas owner does not accept Chinese standards?
A: This is a common challenge. Three strategies are typically adopted: first, provide comparative assessment reports between Chinese standards and Anglo-American standards to demonstrate technical equivalence; second, recheck key structures per the owner's designated standards; third, obtain verification reports from authoritative third-party institutions. For specifics, please refer to the project contract terms.
Q3: How to handle situations where local materials cannot meet Chinese standard requirements?
A: An equivalence substitution assessment procedure must be initiated, verifying through testing whether local materials meet design performance requirements. If they cannot, consider importing materials or adjusting the design solution, and submit to the owner for approval.
Q4: How do CHEC Standards interface with FIDIC contract conditions?
A: FIDIC is a contract management framework, while CHEC Standards are technical execution standards—they operate at different levels. Under FIDIC contracts, technical standards are typically stipulated in the "Specification Requirements" clause. CHEC Standards can serve as the contractor's technical solution basis but require the Engineer's approval.
Q5: How can one obtain the complete text of CHEC Standards?
A: CHEC Standards are internal corporate documents and are not publicly released. To understand specific technical clauses, it is recommended to use project cooperation channels or consult relevant published technical papers. For specifics, please refer to official documents.
1. Pre-contract review: Clarify the applicable technical standards system at the bidding stage, assess the gap between CHEC Standards and contract requirements, and develop adaptation plans in advance.
2. Establish a standards comparison table: For the host country, compile a three-way comparison table of Chinese standards, international standards, and local standards as a quick reference tool for design and construction.
3. Localization assessment first: Conduct early research on local materials, labor, and equipment resources, and develop an equivalence substitution assessment report template to shorten approval cycles.
4. Strengthen bilingual capabilities: Technical documents, acceptance materials, and communication records must all be bilingual in Chinese-English (or the local language) to reduce quality disputes caused by language differences.
5. Localize the HSE system: While following the CHEC HSE framework, embed local environmental and labor law requirements to avoid compliance risks.
6. Digital management tools: Adopt BIM, project management software, and other digital tools to achieve traceability and auditability of standard implementation processes.
7. Lessons-learned review mechanism: After each project, conduct a standards applicability review and feed new experience back into corporate standard revisions, forming a continuous improvement loop.
8. Early alignment with owner's consultants: Reach consensus on standard applicability with the owner's engineer at the design stage to avoid rework during construction.
