Background 

With the rapid development of China's economy and urbanization, the number of high-rise buildings and old residential communities is increasing rapidly. Secondary water supply has become an indispensable part of urban water supply.

At the same time, in order to promote the development of the secondary water supply industry, China has promulgated a number of relevant policies to support, encourage and standardize the secondary water supply industry. For example, the "Notice on Strengthening and Improving the Construction and Management of Secondary Water Supply Facilities for Urban Residents to Ensure Water Quality Safety" jointly issued by four national ministries and commissions, etc. The secondary water supply industry has ushered in a golden opportunity for vigorous development and is presenting a thriving scene.

However, regardless of whether it is a high-rise building or an old residential community, the traditional construction methods of secondary water supply all have the same difficulties and pain points. Issues such as tight construction schedules, heavy tasks, relatively high material losses, a high rate of rework, construction inconvenience due to insufficient construction space, noise and dust pollution, and disturbing the residents have been plaguing many construction units.

In view of this, Flangco Water has applied BIM technology to the construction of secondary water supply projects and introduced a comprehensive BIM prefabricated solution. This solution effectively addresses various problems encountered in secondary water supply projects, making the construction safer, more stable, and more efficient! It also helps to reduce costs, increase benefits, and enhance the financial viability!

Benefits of BIM Application

Building Information Modeling(BIM), namely Building Information Modeling technology, is a multi-dimensional model information integration technology that integrates various technologies such as Computer-Aided Design (CAD), Computer-Aided Manufacturing (CAM), and Computer-Aided Engineering (CAE). It is a digital carrier and visual expression of the physical characteristics and functional characteristic information of construction projects.

Based on three-dimensional digital technology, BIM is an engineering data model that integrates various relevant information of engineering projects. It provides coordinated, internally consistent, and computationally analyzable information for design, construction, and operation and maintenance. It can be applied to various stages of water affairs engineering, including planning, surveying, design, construction, operation and maintenance, etc. It enables data sharing among all parties involved in the whole life cycle of water affairs engineering based on the same multi-dimensional building information model, providing technical guarantees for data connectivity, intelligent construction, and the construction of smart water affairs.

 BIM DESGIN 

1.Collision Detection:
Collision detection is an important symbol of the transition from the 2D era to the 3D era. Through comprehensive "3D review", a large number of problems hidden in the design can be discovered. Theoretically, all kinds of collisions can be eliminated 100% before the actual construction, reducing rework, shortening the construction period, and saving costs.

Flangco's comprehensive BIM prefabricated solution, through its powerful pipeline comprehensive design capabilities and digital management of the building model, realizes integrated management and collaborative work for various aspects such as the building structure, equipment, and pipelines. It can synchronize in real time and accurately optimize and adjust the drawing scheme, effectively avoiding problems such as pipeline intersection collisions in the later stage.

2.Reserved Holes:
BIM design can automatically generate sleeves of corresponding sizes at the pipe penetration positions. If there is a requirement for passing through the wall, the wall-penetrating area can be set in advance, and the wall-penetrating range of this area can be automatically determined, reducing the workload of frequent verification of structural openings between the equipment specialty and the structural specialty. The BIM pump room design is intuitive, makes full use of the space, can reasonably utilize the clear height of the pump room, and effectively avoids prominent structures such as beams and columns for the water tank manholes and ventilation holes.

3.Clear Height Analysis:
Through the simulation of pre-construction in BIM design, the clear height of each area can be vividly, intuitively and accurately represented. According to the clear height requirements of each area and the pipeline arrangement scheme, a clear height analysis is carried out. Parts that do not meet the clear height requirements, functional and aesthetic needs are discovered in advance and corresponding adjustments are made to avoid design changes in the later stage.

4.Clearance Optimization:
According to the primary deepening results of the pipeline comprehensive design, check whether the clear height of the pipeline fitting area meets the specification and usage requirements. By optimizing the spatial layout, it is ensured that the clear height meets the requirements. Discover and solve problems in advance, improve the design quality, reduce construction changes, and save costs for the construction unit.

5.Layout Optimization:
Based on the overall layout requirements, BIM design proposes solutions to eliminate collision points and solve problems such as "errors, omissions, collisions, and deficiencies". At the same time, it can reasonably adjust the routes, elevations of each pipeline, and the positions of pipeline fittings and valves, etc., and optimize the overall layout of the comprehensive pipelines to make them neater, more beautiful, convenient for installation and operation.

6.Hanger Optimization:
Using the 3D model creation function, BIM design conducts a reasonable 3D layout of the pipelines of each installation specialty in this project. It not only meets the specification requirements but also satisfies the requirements of the construction space. It is beautiful and regular, and can also provide technical data for prefabrication and comprehensive hangers.

 BIM Prefabricated Installation 

Flangco's BIM prefabricated installation involves adding information such as various equipment models, dimensions, and installation spaces in a 3D model. Through digital management, a prefabricated solution for the production and installation of secondary water supply equipment with accurate data is designed, and demand information such as the dimensions and positioning of pipelines and supports at various locations is accurately outputted. It truly realizes the prefabrication of modules in the factory and the prefabricated installation at the construction site, effectively avoiding excessive material losses and saving construction costs.
