Shenzhen

On April 2, the Shenzhen Municipal Bureau of Housing and Construction issued a notice titled "On the Work Related to the Functional Optimization and Launch of the Shenzhen Construction Project Survey and Design Management System":

The notice clearly requires:

All newly built (approved, verified and filed) engineering projects (with an investment of more than 10 million yuan and a construction area of more than 1,000 square meters) must submit the BIM model through the management system after the BIM model is created.    

Shanghai

In addition, as early as February this year, Shanghai launched the BIM review system:

   

According to the requirements of relevant municipal documents, starting from February 1, 2024, the municipal engineering approval system launched theBIMmodel technology intelligent assisted review subsystem. The details are as follows:

         
1. System Functions and Trial Scope

(1) System Functions 

The system functions include Building Information Model intelligent assisted review (hereinafter referred to as "BIM Review") and structural discipline 2D intelligent assisted review (hereinafter referred to as "Structural 2D Review"). (The following only explains the BIM Review; for the structural discipline 2D intelligent assisted review, you can download the attachment to view the original text.)

BIM Review is the intelligent assisted review of certain specification indicators 12 for disciplines such as architecture, structure (load review), water supply and drainage, HVAC, and electrical, implemented on the BIM models of building construction projects.

          

(2) Trial Scope 

The trial scope of the BIM Review is the newly built, renovated, and expanded building construction projects in this municipality that should implement BIM technology applications.

Pudong New Area may, according to the actual conditions of promoting high-level reform and opening up, expand the trial scope, extend the review functions, and carry out pioneering trials.

              

         
2. Trial Period

Starting from February 1, 2024, projects within the trial scope must be uploaded; past projects may be submitted voluntarily.

          

Why BIM Drawing Review?

          

A word from the editor: Building drawing review is a multi-discipline comprehensive inspection of architectural design drawings, and is a necessary step before construction. The depth and scope of drawing review will, to a certain extent, affect the quality, safety, cost, and progress of construction.

          

BIM drawing review is an entry-level application in BIM technology application. It mainly refers to using BIM technology to perform clash and specification checks after multi-discipline integration of the building 3D model, quickly, accurately, and comprehensively identifying errors, omissions, clashes, and deficiencies in the design drawings, minimizing construction rework, saving costs, and ensuring a smooth transition of the construction project from the design side to the construction side.    

          

Drawing review involves the interests of multiple parties: the project owner, the designer, and the contractor. Through drawing review, mutual conflicts between building components can be predicted in advance and communicated visually, improving collaboration among project staff and achieving significant economic benefits.BIM drawing review can eliminate about 90% of drawing errors; reduce about 60% of construction rework and corresponding material losses; speed up construction progress by about 10%; greatly improve model accuracy; and enhance the efficiency of contract quantity calculation.
