主 题：Project management Cost Significant Items(CSIs) Engineering costing Intelligent estimation
摘 要：Against the backdrop of rapid development in China’s construction and infrastructure sectors,discrepancies between project budgets and actual costs have become pronounced,manifesting in project overruns and suspensions,posing significant *** address inaccuracies in investment targets and operational complexities,this study focuses on a beam-bridge construction project in a district of Shijiazhuang city as a case *** upon historical analogs,the project employs a Work Breakdown Structure(WBS)to decompose the engineering *** on theories of Cost Significant(CS)and Whole Life Costing(WLC),the study constructs Cost Significant Items(CSIs)and develops a CNN-BiLSTM-Attention neural network for nonlinear *** identifying significant cost drivers in engineering projects,this paper presents a streamlined cost estimation method that significantly reduces computational burdens,simplifies data collection processes,and optimizes data analysis and forecasting,thereby enhancing prediction ***,validation with real-world cost fluctuation data demonstrates minor errors,meeting predictive requirements across project execution phases.
