the bidding stage modularization feasibility assessment method of the decision system in the bidding process of construction work

摘要

The present invention is to review the bid feasibility by using a dedicated application for related data after the construction bid announcement, (1) ITB review step of reviewing the tender notice (ITB) announced by the construction client; (2) the initial investigation stage; (3) bid feasibility review stage; (4) a feed step; (5) preparation of technical bid (TP) and calculation of construction cost; It provides a decision-making system for the bidding stage of construction construction, characterized in that it comprises a Between steps (1) and (2), (G1) Based on the bidding notice (ITB) reviewed in step (1), major ITB review items including construction details and quantity are selected, filtered by ITB review criteria including risk and profitability, and a predetermined standard is passed. (2) provides a decision-making system for the bidding stage of the construction construction, characterized in that it includes; Between steps (2) and (3), (G2) Select the main initial investigation review items including detailed construction details and detailed quantities reviewed in step (2) above, filter by initial survey review criteria items including risk and profitability, and go to step (3) when the predetermined criteria pass It provides a decision-making system of the bidding stage of construction construction, characterized in that it includes; the second stage of the gate passing. Also, In the decision-making system of the construction bidding stage to review the bid feasibility by using the dedicated application for the relevant data after the construction bid announcement, categories including schedules, costs, and site characteristics; Detailed elements including time reduction, cost, and cash flow that are classified and linked under the category; Consists of including, The category and the detailed element provide a modular method for the initial bidding stage in the decision making system of the construction construction bidding stage, characterized in that each of the categories and the detailed elements are quantitatively quantified by numerically assigned a predetermined weight. together, The details are It is characterized in that it is selected as a specific value and modularized, Provided is a modularization method for the initial bidding stage in the decision making system of the construction construction bidding stage, characterized in that the weight and the specific numerical value are multiplied to become a weighted score. And in the decision-making system of the construction construction bidding stage to review the bid feasibility by using the dedicated application for the relevant data after the construction bid announcement, (1) a manufacturing shop selection step in which the preconditions including the sales of the manufacturing company and the factory size are input and the manufacturing company is selected; (2) a module condition input step of inputting module conditions including road width and turning angle; (3) a module constraint condition determining step of determining a final module condition by comparing the module conditions; (4) a module design step of deriving a free module list by creating a module list and applying module variables considering the ratio and size; Provides a bidding stage modularization method in the decision-making system of the construction construction bidding stage, characterized in that it comprises a After step (4), (5) a module list input step of inputting a BOQ (Bill of Quantity) for each free module list by combining the design quantity of the module corresponding part; (6) a production and transportation cost calculation step of calculating the module quantity and module production cost based on the BOQ (Bill of Quantity); It provides a method for modularizing the bidding stage in the decision-making system of the construction construction bidding stage, characterized in that it comprises a. And in the decision-making system of the construction construction bidding stage to review the bid feasibility by using the dedicated application for the relevant data after the construction bid announcement, (1) a manufacturing shop selection step in which the preconditions including the sales of the manufacturing company and the factory size are input and the manufacturing company is selected; (2) a module condition input step of inputting module conditions including road width and turning angle; (3) a module constraint condition determining step of determining a final module condition by comparing the module conditions; (4) a module design step of deriving a free module list by creating a module list and applying module variables considering the ratio and size; It is characterized in that it comprises a Wr : road width, θ: rotation angle, r : turning radius, L: module length, W: module width The modular condition provides a method for modularizing the bidding stage in the decision-making system of the construction construction bidding stage, characterized in that determined by the above formula. together, In the decision-making system of the construction bidding stage to review the bid feasibility by using the dedicated application for the relevant data after the construction bid announcement, (1) Function rearranging step of organizing functions including functional nouns and functional verbs according to cost classification items (CBS); (2) an idea addition step of adding an idea, which is an additional item according to a function, according to the cost classification item (CBS); (3) an idea evaluation step in which a quantitative value is assigned to each evaluation item including functionality, economic feasibility, safety, and environmental characteristics in a state in which a predetermined weight is assigned; (4) an alternative materialization step of presenting a plurality of alternatives by calculating a plurality of life cycle costs (LCC, life cycle cost) that can be compared according to the cost classification item (CBS); (5) a target determination step of determining an optimal alternative among the plurality of alternatives; Provides a VE decision-making system in the decision-making system of the construction bidding stage, characterized in that it comprises The step (4) is, It provides a VE decision-making system in the decision-making system of the construction bidding stage, characterized in that the performance is scored numerically based on the importance and the evaluation grade for each evaluation item.
