ABSTRACT

When a new hospital construction project is tendered, there exists risk of cost, budge deviation whether the budget preparation of the organization responsible for the project or the preparation of the construction company before participating in the bidding. Therefore, during the construction cost estimation process, various possible factors must be evaluated carefully to ensure the accuracy and reliability of the cost estimation. In the past, the most common method of estimating used empirical rules, assuming and calculating the approximate quantity of materials based on experience, and then multiplying by the appropriate unit price to obtain the project cost. However, this method is easily affected by human factors. This leads to incorrect assessment of expected profits. If construction costs are underestimated, it may lead to insufficient funds during the project, affecting the quality and safety of the project, and creating a crisis that requires additional funds or affects the progress of the project.
Therefore, this study takes the hospital construction project as an example, divides the construction cost into five estimation modules: foundation engineering, structural engineering, exterior wall decoration engineering, door and window engineering and the total amount above the ground floor, and uses the regression equation to estimate the module For verification, we use the reasonable contracting price in the past as the benchmark cost to calculate the standard deviation of the estimated cost. Finally, we analyze and select the most accurate indicator factor in the estimation module as the best estimation parameter.The research results show that the best estimated parameter for the foundation engineering cost of a hospital building is the number of parking lots, the best estimated parameter for the structural engineering cost is the number of beds, the best estimated parameter for the exterior wall decoration project cost is the building area, and the cost of door and window engineering. The best estimated parameter for the total cost above the ground floor is the floor area above the ground.To sum up, the construction cost estimation of the hospital constructed in this study can use the four parameters of parking number, number of hospital beds, building area and area above the ground to quickly and accurately estimate the construction cost of the hospital construction project. Decision makers can set profits reasonably so that funds can be allocated more effectively.
