Key contract clauses are missing or ambiguously worded, leading to major disputes during performance.
Construction contracts are legal documents governing the rights and obligations between the employer and the contractor. The completeness and clarity of contract clauses directly affect whether the contract can be performed smoothly. In actual projects, missing or ambiguously worded contract clauses are a common cause of performance disputes. The scope of works and interfaces are not clearly defined, and the contract does not accurately describe the specific scope of the contracted works and the interface demarcation with other sections. The change management procedure is not clearly agreed, and the contract does not specify in detail how design changes are proposed and the approval process. The price adjustment mechanism is missing or too general, with no mechanism agreed for price adjustments caused by fluctuations in material prices. Liability for breach is unbalanced: the employer sets strict liquidated damages for the contractor's breaches but lacks corresponding provisions for its own breaches. From a standards perspective, GF-2017-0201 "Construction Contract for Construction Projects (Model Text)" provides a standard template for the general clauses of construction contracts, but some tenderers simplify or modify contract clauses on their own, resulting in contract defects. From the perspective of operational impact, the direct consequence of missing or vague key contract clauses is frequent disputes during performance. At the settlement stage, the ambiguities in contract clauses often become the focus of bargaining between the parties. From a cost data perspective, the amount of cost disputes caused by unclear contract clauses typically accounts for 3%-8% of the total contract price, and litigation and arbitration costs are 10%-20% of the disputed amount. The core measures to solve such problems include mandatory use of the model contract texts recommended by the state or industry, and establishment of a contract review and countersignature system, with the project manager, legal personnel, commercial lead and the responsible executive reviewing and countersigning level by level. From the systems engineering perspective of engineering management, solving this problem requires coordinated advancement across four dimensions: institutional design, process control, technical support and culture building. At the institutional design level, clear responsibility boundaries and operating procedures must be established, translating regulatory requirements into executable job responsibilities and work standards. At the process control level, full-lifecycle quality supervision and dynamic correction must be implemented to ensure that the work results of each stage meet the expected objectives. At the technical support level, information-based methods and intelligent tools should be actively introduced to improve the precision and efficiency of management. At the culture building level, quality awareness and compliance awareness must be cultivated among all staff to create an organizational atmosphere that pursues excellence. Only by organically combining these four dimensions can the recurring common quality defects and persistent management problems in engineering construction be fundamentally solved, achieving continuous improvement and excellent performance in project management.
