Application of BIM Technology in electrical and mechanical engineering of commercial buildings


Now when the detailed design construction drawing is produced, it is only after the model has passed the inspection that the model is used to produce the construction drawing

.

There are also the material statistics of the project, the three position plane and vertical section views of the key parts of the project, and the construction simulation

.

Solution: the BIM visualization function is used for pipeline collision detection to minimize the on-site pipeline collision and rework at the first time, reflect the cost reduction and efficiency increase in the most practical way, and practice the concept of low-carbon construction

.

What is the application of Bim in mechanical and electrical installation industry? The application of two-dimensional plan and three-dimensional model at different levels can be arranged according to the project situation, the owner’s requirements and the construction period

.

It has the characteristics of visualization, coordination, simulation, optimization and plotting

.

Project Description: B4, B3 and B2 floors are garage (B4 floor is civil air defense material warehouse and personnel shelter in wartime), B1 floor is equipment room, B1 mezzanine is self-propelled garage and power transformation and distribution room, water pump room, reclaimed water room, etc

.

It also includes air conditioning fresh air system, air conditioning supply and return air system, air conditioning ventilation system, fire ventilation system, air conditioning water system, domestic water supply system, domestic hot water system, domestic sewage system, power transformation and distribution and emergency power supply system, power distribution system, lighting system, intelligent lighting control system, integrated wiring system, radio and television wiring system, bas building and automatic control system System, fan coil control system, sound reinforcement system, cable TV system and other systems

.

Therefore, we can use the model to prefabricate, improve work efficiency, and facilitate the maintenance of owners in the future, so as to play the role of data and information sharing

.

04 construction simulation progress control with BIM model can achieve four-dimensional simulation

.

It includes the synthesis of pipelines, the collision between pipelines and building structures, and the generation of collision detection report

.

02 pipeline comprehensive problem: how to cooperate with civil engineering and Decoration Specialty in real time and make rational use of installation space has always been a difficult problem for the industry

.

Solution: BIM professional software can be used at the beginning of the project to carry out the in-depth design of mechanical and electrical specialty

.

In this process, we should often communicate with the design and construction units

.

It can not only intuitively reflect the interface and sequence of construction, so as to make the construction coordination between general contracting and various professional construction clear; through the combination of four-dimensional construction simulation and construction organization scheme, it can make the arrangement of equipment and materials mobilization, labor allocation, mechanical layout and other work become the most effective and economic

.

03 BIM model of prefabrication can be used and modified repeatedly, and all kinds of accessories models of mechanical and electrical specialty are described accurately

.

Later stage: the design and layout of fine decoration is a more detailed model and its application in later operation and maintenance management Through collision between air ducts, collision between cable tray and air duct and beam solved by pipe bending, collision between bridge and water pipe solved by adjusting elevation, collision between air and water pipes after adjustment, plane, three-dimensional and section views of the ground floor of the refrigerator room after adjustment, and material statistics of three-dimensional, elevation and section views of the equipment in the machine room presentation.

.

the ground is divided into North and South towers, more than three floors are linked by corridor, 1 F is exhibition room, office area and fire control room; 2f-19f includes office area, meeting room and dining area; 20f is rest room, meeting room, elevator and other mechanical and electrical rooms; refrigeration room and heat exchange station of air conditioning and hot water are located on B1 floor

.

Make our model practical, and lay the foundation for later application in management

.

Check the communication between the drawings and the Design Institute, and go to the construction site to communicate with the construction personnel

.

Mechanical and electrical, architectural, structural BIM model: from the beginning to get the drawings to do the preparatory work and project template customization, clear the short-term goals and long-term goals

.

The equipment hoisting scheme and some important construction steps can now be clearly displayed to the owner and the approval party in the form of four-dimensional simulation

.

In the comprehensive process, it can meet the requirements of various national specifications, meet the requirements of system use, avoid redundant pipe fittings as far as possible, reduce system resistance, reserve enough maintenance space, consider the purchase and production of actual pipe fittings, and consider the production and installation of supports and hangers

.

Medium term: through the collaborative work mode of central file project, realize the collaborative work of architecture, structure and mechanical and electrical disciplines, which can update the model in real time, coordinate various problems among disciplines, communicate in time, find and solve problems

.

BIM is based on the relevant information data of the construction project as the basis of the model to establish the building model, and simulate the real information of the building through digital information simulation

.

01 collision detection problem: 2D drawings can not fully reflect the possibility of collision among individuals, specialties and systems; at the same time, due to the unpredictability of discrete behavior of 2D design, designers will miss some problems of pipeline collision

.

The layout of key equipment room should consider the rationality of space and aesthetic feasibility
