在工程量清单计价模式下,由于招标工程量与竣工工程量存在差异,投标单位采用不平衡报价,会导致建设管理单位存在超概算的风险。本文在深入分析投标单位投标策略的基础上,构建不平衡最优报价模型,得出投标单位的最优报价;然后以山西省某输变电工程为例,采用蒙特卡罗模拟法,构建了输变电工程造价风险评估模型,对建设管理单位所面临的风险进行了度量,并提出改进措施,以减少超概算发生的概率。研究结果对工程造价管理具有一定指导意义,可以规范招投标规则,使输变电工程建设健康、合理、可持续地发展。
在工程量清單計價模式下,由于招標工程量與竣工工程量存在差異,投標單位採用不平衡報價,會導緻建設管理單位存在超概算的風險。本文在深入分析投標單位投標策略的基礎上,構建不平衡最優報價模型,得齣投標單位的最優報價;然後以山西省某輸變電工程為例,採用矇特卡囉模擬法,構建瞭輸變電工程造價風險評估模型,對建設管理單位所麵臨的風險進行瞭度量,併提齣改進措施,以減少超概算髮生的概率。研究結果對工程造價管理具有一定指導意義,可以規範招投標規則,使輸變電工程建設健康、閤理、可持續地髮展。

In the bill-of-quantity mode, as there are some di- fferences between bidding engineering quantity and compl- eted engineering quantity, the unbalanced quotation adopted by bidding companies may lead to the probable risk to construc- tion companies. Based on the thorough analysis on the bidding strategies of bidding companies the optimal unbalanced biddi- ng model was built to acquire the optimum price quotation. Then, with Monte Carlo simulation method cost risk evaluati- on model of power transmission and transformation projects was built to measure the risk of construction companies. The appropriate measures were used according to the risk scale, which could minimize the happening of excess budgetary esti- mate. The research results have guiding significance to the en- gineering cost management, and wil standardize the bidding rules for the health, reasonable and sustainable development of the construction of power transmission and transformation pr- ojects.
