The estimation of engineering costs plays a significant role in various phases of engineering projects.However,traditional estimation methods suffer from issues such as lack of precision,poor comparability,and low levels of informatization.As a response to these challenges,emerging technologies,often based on statistical or machine learning methods,have introduced new perspectives to engineering cost estimation.Nevertheless,they still face limitations such as a narrow range of calculation methods and inflexibility in the results.To address these issues,this paper proposes an advanced engineering cost estimation system aimed at enhancing flexibility,scalability,comparability,and accuracy in estimation.The system design is based on a modular approach,integrating various estimation methods as atomic operators.It combines top-down decomposition and bottom-up aggregation to estimate engineering costs comprehensively.Furthermore,a related intelligent system is designed.Future research will continue to optimize the system,further elevating its level of intelligence.This engineering cost estimation system will provide a reliable tool for project management and decision-making,contributing novel perspectives and methodologies to the field of engineering estimation.
Mainland construction enterprises have made significant contributions to Hong Kong's infrastructure construction.While Hong Kong continues to develop infrastructure construction,it becomes a problem for mainland enterprises to represent their advantages in bidding for public works in Hong Kong and accurately and efficiently calculate bidding price.The measurement rules for Hong Kong projects are complex,and consulting firms are highly professional.These bidding proposals could only be generated after carefully predict,plan,calculate,and analyze the cost of the project.Bidding team must pay attention to the analysis of the main resource inputs,spare no effort to refine the bidding technical and economic plans,and improve the competitiveness of enterprises,in order to ensure that Mainland enterprises are invincible in the fierce international competitive market.This article analyzes the key points of reviewing the Hong Kong public bidding document and proposes two suggested methods for bidding quotation.
各省、自治区、直辖市、新疆生产建设兵团社会信用体系建设牵头部门、招标投标指导协调部门: 当前,一些地方通过信用评价、信用评分等方式设置招标投标隐性壁垒,破坏公平竞争的市场环境,阻碍全国统一大市场建设,必须坚决纠正规范.
Engineering cost management is a key difficulty in EPC project management.Due to the professionalism and complex structure of construction projects,engineering cost control has become even more difficult.In order to solve this problem,a third-party consulting agency is introduced.Third party consulting agencies can promote deep participation from all parties,build a new collaborative mechanism,and promote the smooth progress of various stages of the project with high standards,thereby achieving effective engineering cost management and control.This article focuses on the characteristics of EPC projects,outlines the challenges faced by third-party consulting when participating in engineering cost management,and proposes a cost management collaboration mechanism based on third-party consulting participation.This mechanism constructs a clear collaborative management operation structure,which helps to solve existing problems.And combined with the EPC project of Minhang District Disease Prevention and Control Center,a detailed introduction was given to the practical application of collaborative management system,hoping to provide useful guidance for the application of third-party consulting in cost management and promote the development of the industry.
This paper uses quantitative analysis to compare the differences between skid-mounted equipment and non-skid equipment and the reasons for the differences from both technical and economic aspects.By collecting the application of various skid-mounted equipment in oil and gas fields and refining and chemical units,and scientifically analyzing the investment data of different types of skid-mounted equipment,the application status of skid-mounted equipment,price composition and the difference between skid-mounted equipment and non-skid-mounted equipment are summarized,and the applicable scope of different types of skid-mounted equipment is summarized and corresponding optimization suggestions are put forward.The research has formed three conclusions:first,the investment in skid-mounted equipment has increased year by year,and it has been widely used in oil and gas field surface engineering and oil refining and chemical engineering;second,on the whole,the investment in skid-mounted equipment is higher than that in non-skid equipment,mainly due to the increase in technical services,profits and other costs after the integration of skid-mounted equipment;third,considering the whole life cycle,the total cost of skid-mounted equipment is low,and it has the advantages of saving time and space.It is recommended to divide the scope of application according to the characteristics of various skid-mounted equipment.
