In the wave of industrial intelligent manufacturing upgrades, the quality of the tender list for new factory projects directly affects investment controllability, construction efficiency, and subsequent performance quality. The new factory project of Guangdong Sanmu Automotive Electronics Co., Ltd., as a key project in the regional automotive electronics industry upgrade, has attracted great attention for the professionalism and accuracy of its general contracting tender list. Shenzhen Ruijie, relying on its full-process cost control capabilities and in-depth service experience, efficiently completed the review of the list, solving project challenges with professional strength and creating a benchmark model for the review of industrial project lists.

Project Breakthrough: Precisely Tackling Complex Challenges
The re-examination task of the tender list for the Sanmu Automobile new factory project faced multiple challenges from the very beginning: First, tight schedule and heavy workload—the original plan was to complete data collection in 3 days and finalize it within 15 days, and the previous tender list review had an inconsistent format, with complicated pricing methods and quantity calculation software, increasing the difficulty of verification; Second, the original list had systemic defects, using the Yida priced list that led to chaotic formatting and complex subdivision, with more than 60 items missing or wrongly opened, and over 80 quantity errors, posing potential risks for subsequent construction and settlement; Third, the entire bidding process involved coordination among multiple departments such as engineering, design, procurement, and cost, and any disconnection in any link could affect the progress of key milestones.
In response to the above challenges, Shenzhen Ruijie quickly formed a specialized service team and established a multi-level organizational structure consisting of 'tender evaluation experts, front-end and back-end technical teams, project managers, and internal audit groups,' creating an efficient response mechanism. During the operation process, they innovatively adopted the 'back-to-back quantity calculation' model, synchronously coordinating multiple departments to overcome bottlenecks: closely following the design drawings to clarify technical standards through Q&A, confirming the boundaries of the tender scope with procurement, aligning the list format and pricing rules with costs, and verifying technical requirements beyond the drawings with the engineering team. The entire process from data integration to finalizing the list was completed in just 21 days, ensuring control over key milestones.
List Renewal: Value Reconstruction from Complexity to Precision
Shenzhen Ruijie, with the core goal of 'simplifying complexity and ensuring precise compliance,' has systematically optimized the original list, achieving a comprehensive upgrade from form to content. The specific results are shown in the table below:

Taking the pile foundation project as an example, the original bill of quantities omitted more than 6,000 meters of 600PHC piles at positions #3 and #4, and 1,787 m³ of C40 concrete for the basement project. After quantity extraction analysis and precise calculation by Ruijie, all items were corrected. For special projects such as doors, windows, and curtain walls, by breaking down the composition of 'labor, materials, machinery, management, and profit' and researching real-time market prices, a traceable unit price analysis table was created, completely resolving the original bill's issues of 'inflated prices and unclear composition.'

Precise Pricing Control: Building Based on Market-Aligned Cost Benchmarks
Through market inquiries and benchmarking against similar projects, Ruijie has prepared a project control price that is at the mid-level of the market. This not only fully considers the current competitive construction market and the industry's trend of winning bids with low profits but also provides the owner with a reliable baseline for bid analysis. Looking at the bidding results, the quotes from the six bidding units all reasonably fluctuated around the estimated price, with the highest quote deviating from the reasonable price by 7.28%, fully validating the scientific rationality of the control price.
Efficient Q&A: Checklist completion rate reaches 98.5%
Facing the project's high complexity, Ruijie followed up on bidding questions throughout the process, ultimately responding to only about 40 questions in the final list, achieving a 98.5% completion rate for the list in a large general contracting project. For key questions such as 'missed items in road earthwork' and 'scope of exterior wall lighting,' the company coordinated with the owner and the designer to quickly clarify boundaries, avoiding disputes during later contract performance.
Strictly Maintain Confidentiality: Ensuring Fair and Just Bidding
As an absolutely confidential core result, the control price adopts a confidentiality mechanism of 'single-person management, scheduled sending' — only the project’s direct contact retains the result, and it is sent to the owner's designated email at a specified time before bidding, thereby eliminating the risk of bid floor leakage from the process and ensuring the fairness and rigor of the bidding process.
Value-Added Empowerment: Upholding Value in the Review Process
While completing the core task of checklist re-review, Shenzhen Ruijie, based on a full project lifecycle perspective, accurately identifies potential risks in cost management and proposes systematic optimization suggestions, highlighting the core values of 'reducing costs, reducing risks, improving quality, and increasing efficiency'.
Target Cost and Dynamic Tracking: In response to the lack of target costs in the early stages of the project and the absence of dynamic updates during the process, it is recommended to set an investment cap and establish a real-time cost tracking mechanism to avoid the risk of overspending and overpayment.
Contract terms deepened: corrected errors in the agreed payment method, added clauses limiting over-reporting deductions, clarified the visa change process, and reduced settlement disputes from the source.
Visa management closed-loop: Implement the 'monthly clearing and settlement' system, requiring visas to have clear descriptions of the matters, responsibility determination, and calculation of work quantities. If not reported within the time limit, they will automatically become void, preventing contractors from falsifying documents and from clustering of visa requests.

Benchmark Insights: Professional Paradigm for Re-examining Tender Lists
The re-examination practice of the Sanmu Automobile new factory project provides a replicable professional model for the re-examination of industrial project bidding lists, highlighting Shenzhen Ruijie's core capabilities in this field:
At the technical and methodological level: the 'back-to-back quantity calculation, multi-department collaboration' model can effectively solve the problems of chaotic quantity lists and inconsistent standards, and is especially suitable for large-scale industrial projects with multiple professional intersections;
Quality control level: From template standardization and format optimization to detailed verification and unit price analysis, the all-dimensional audit process can systematically solve the problem of 'errors, omissions, and missing items,' improving the accuracy of the list.
Service assurance level: The service system of 'rapid response team, confidentiality mechanism, and Q&A closed loop' not only ensures that the milestones of urgent projects are controllable but also upholds the fairness of bidding and the baseline quality of the list.
From efficiently breaking through challenges head-on, to reconstructing value through refreshed checklists, and then to upholding value through professional details, Shenzhen Ruijie, with the mission of 'Connecting trust with care, achieving quality life,' has solidified the core foundation of the bidding stage for the Sanmu Automobile new factory project. In the future, Ruijie will continue to deepen its efforts, helping enterprises achieve the core goals of 'reducing costs, lowering risks, improving quality, and increasing efficiency.'
