Enclosure engineering is a kind of facility that isolates the construction site from the external environment and makes the construction site a relatively closed and isolated space. Depending on the construction site and conditions, the specific setting of the enclosure project will also be different. Generally speaking, the construction project must be fully enclosed, and the height of the main road or the largest place in the urban area shall not be less than 25 meters, other places shall not be less than 18 meters. The so-called semi-closed refers to the establishment of enclosures on two or three sides, and one or both sides are open to facilitate the entry and exit of construction machinery and materials.
How to set up the specific should be determined according to the bidding documents, drawings, on-site environment, and construction organization design under the condition of ensuring safety. For example, if a municipal project is carrying out road maintenance in a downtown area, it is necessary to enclose the fence to ensure that no pedestrians will enter the road and cause danger. In the case of a new road in the suburbs, only one side of the fence and one gate need to be set up at the junction of the old and new roads, and the other three sides can be left unsealed.
1. Determine the scope of the projectBefore the preparation of the cost of the enclosure project, it is first necessary to clarify the specific scope and requirements of the project. This includes determining the type, height, material, color, size, etc. of the enclosure, as well as the specific content of the construction, such as foundation treatment, installation method, transportation method, etc.
2. Collect information.
In order to ensure the accuracy and completeness of the preparation of project cost, it is necessary to collect relevant information and data. This includes:Construction drawings and design instructions:The construction drawings are the basis for the preparation of the project cost, which provides information such as the specific structure and size of the enclosure project. The design description provides information such as specific requirements and standards for fencing works.
Bill of Quantities:The bill of quantities provides information such as the quantity and specifications of the various sub-items of the enclosure project.
Material ** Information:Material information provides information on the market and situation of various materials. Labor Cost Information:Labor cost information provides information such as labor cost standards and market standards for different types of work.
Additional Fee Information:Other cost information provides information such as the standard and amount of other costs that may be incurred during construction.
3. Calculate the engineering quantityAccording to the construction drawings and design instructions, combined with the bill of quantities, the calculation and statistics of each sub-project of the enclosure project. This includes the number and size of the various components of the enclosure (e.g., columns, beams, wall panels, etc.).
Fourth, determine the materials**According to the material information and the actual needs of the enclosure project, determine the required materials of various materials. This includes the quality, specifications, quantity, etc. of the material.
5. Calculate labor costs.
According to the labor cost information and the actual demand of the fence project, determine the required labor cost. This includes the workload and wage rates for each type of work. 6. Consider other expenses
According to the information of other costs and the actual situation of the enclosure project, consider the other costs that may be incurred. This includes construction machinery usage fees, transportation costs, insurance fees, etc.
7. Determine the cost of the project
Through the calculation and evaluation of the engineering quantity, materials, labor costs and other expenses of the enclosure project, combined with the relevant pricing standards and regulations, the total cost of the enclosure project is determined. In this process, it is necessary to consider factors such as market competition and risk, and make reasonable adjustments and corrections to the project cost.
