通过梳理天津输变电工程中顶管项目常见的典型技术方案,利用市政定额编制对应不同典型方案的顶管施工图预算,提取并量化各方案的主要造价影响因素,研究制定不同技术条件下顶管工程造价预测模型,并将该模型运用于输变电工程可研估算、初设概算、招投标、结算等全过程造价管控中,由此提高输变电工程全过程造价精益化管理水平。 By combing the typical typical technical solutions of the pipe jacking project in Tianjin power transmission and transformation project, the budget of pipe jacking plans corresponding to different typical schemes is formulated by the municipal fixed quota, the main cost influencing factors of each scheme are extracted and quantified, This model is applied to the cost control of feasibility study, initial estimation, bidding and bidding, settlement and so on, thus improving the lean management level of the whole process of transmission and distribution project.
