Core Business Decision Tips:
1. Project Opportunity: The core civil engineering project for the ventilation system renovation at the Wuhushan Coal Mine of China Energy Group Wuhai Energy Company, including new ventilation fan rooms, power distribution rooms, air duct foundations, and site supporting facilities. This is a key project for upgrading coal mine safety production, with guaranteed funding, suitable for enterprises with experience in industrial and civil construction engineering.
2. Clear Entry Barriers:
Qualification Requirements: Must hold a Grade 3 or above General Contracting Qualification for Construction Engineering and a Work Safety Permit. Bidders without these cannot participate.
Corporate Performance: Must provide 2 construction engineering contracts dated from March 2021 onwards; this is a hard requirement.
Project Manager: Must assign a Grade 2 or above Constructor (Construction major) with a Category B certificate and have 1 project manager performance. Personnel cannot be borrowed; must be employees of the bidding company.
3. Special Points Regarding Schedule and Pricing:
The construction period is 210 days, but excludes the winter shutdown period. The actual construction cycle will span at least one winter, which must be fully considered in the schedule.
Night shift operations for underground coal mines have been canceled in Wuhai. This means all civil construction work can only be conducted during daytime, significantly impacting schedule planning and labor organization. This efficiency reduction and associated cost changes due to the inability to work at night must be considered in the bid price.
4. Tight Timeline:
Bid Document Purchase Deadline: 16:00, February 28, 2026 (8 days remaining).
Bid Submission Deadline: 09:00, March 11, 2026 (approximately 19 days of preparation time remaining, including bid preparation, CA certificate processing, personnel documentation organization, etc.).
5. Mandatory Fully Electronic Bidding:
Must operate through the Guoneng e-Bidding Platform; requires prior completion of supplier registration and CA digital certificate processing.
Must download and use the "Guoneng e-Bidding Document Preparation Tool" to prepare bid documents.
It is recommended to immediately initiate the registration and CA processing procedures to avoid delays affecting bidding.
6. High Information Transparency: During the bid opening and winning candidate publicity stages, corporate qualifications, performance, and project manager information will be disclosed. Performance information must be authentic and verifiable; false materials will lead to disqualification and potential blacklisting.
7. Competitive Landscape: This project is a medium-sized industrial civil engineering project. It is expected that construction enterprises with Grade 3 or above general contracting qualifications from Wuhai and surrounding areas (e.g., Ningxia, Western Inner Mongolia) will actively participate. Enterprises with experience in coal mine or industrial site construction, capable of properly planning daytime work schedules, and with experienced project managers will have an advantage.
8. Recommended Next Steps:
Immediately Self-check Qualifications: Confirm possession of Grade 3 or above General Contracting Qualification for Construction Engineering and a valid Work Safety Permit.
Immediately Verify Performance: Prepare scanned copies of 2 construction engineering contracts dated from March 2021 onwards, ensuring key information is clear.
Immediately Secure Project Manager: Confirm the validity of the proposed project manager's Constructor Certificate and Category B Certificate, and prepare proof documents for their 1 project manager performance.
Immediately Process CA Certificate: Log in to the Guoneng e-Bidding Platform and follow the instructions to process the CA digital certificate.
Immediately Purchase Documents: Complete the purchase of bidding documents before 16:00, February 28.
Carefully Study Technical Documents: Focus on reading "Chapter 7 Technical Standards and Requirements" to understand technical points for specialized works like slope protection, fan foundations, cable trenches, etc.
Develop Special Schedule Plan: Clearly reflect the impact of "daytime-only operations" on the construction period and corresponding measures in the construction organization design, and reasonably reflect related costs in the bid price.
