The Three Key Elements of BIM Planning for Design Firms
Talents, Processes, and Delivery Models
In recent years, the rise of BIM (Building Information Modeling) in the industry has led many design firms to develop a group of BIM experts, often emerging from passionate enthusiasts. These specialists have addressed some of the limitations of BIM tools—especially the lack of localization—and have applied BIM partially or fully in various projects, often producing results focused on BIM visualization. Consequently, both the scale and quality of works showcased in industry BIM competitions have steadily improved.
However, only a few design firms have successfully integrated BIM as an inherent part of their enterprise productivity. This suggests that many companies remain caught in some common misconceptions about BIM implementation.
While it is important to consider external factors such as tool completeness, owner maturity, and BIM standards, Chinese design firms, given the rapid growth of China’s construction sector and significant market potential (especially for leading enterprises), must adopt a forward-thinking approach to enterprise-level BIM planning.
When it comes to BIM planning, three essential elements are indispensable for design firms. A systematic and comprehensive approach to these elements involves developing BIM implementation standards tailored to the enterprise, based on the China BIM Standard Framework System (CBIMS) released by the BIM research group at Tsinghua University. This process also draws upon the Implementation Guidance Manual for CBIMS in the Design Industry (tentative title), jointly developed by Tsinghua University and Dongjing Tianyuan/isBIM, while aligning with the company’s actual situation.
The Basic Framework for BIM Implementation Standards Includes:
Based on the CBIMS framework, BIM planning for design firms should address the following four core areas:
1. Establishing Enterprise BIM Design Resource Standards
1) Define and re-examine personnel roles under the new BIM design model. This includes roles such as enterprise-level BIM chief engineer, BIM project manager, and BIM design assistant. Given that BIM represents a revolution in engineering, talent shortages are inevitable. Companies may adopt flexible talent strategies—for example, hiring external consultants as BIM chief engineers, outsourcing BIM design assistants, while focusing on cultivating BIM project managers internally.
2) Adjust or redefine the organizational structure to accommodate new and expanded roles. For instance, many firms should enhance their solution rooms by adding more content and adjusting fee structures for BIM-based solutions, linking these directly to business operations.
3) One major barrier to BIM adoption is the lack of comprehensive component resource libraries. Responsibility for developing these libraries should rest with the enterprise rather than individual projects. Establishing component resource coding simultaneously can create added value after delivering BIM-based design results.
4) The absence of standardized data exchange and storage protocols is another significant challenge. While national and industry standards emphasize that data standards should not be dictated by software vendors, in the absence of widely accepted third-party standards, enterprises can pragmatically adopt mainstream software data formats as structural data standards—a practical, simple, and cost-effective solution.
5) Additional standards related to design resources—such as hardware specifications, network environments, file naming conventions, and supporting information systems—can be planned and implemented by specialized firms.
2. Developing BIM Design Behavior Standards Suitable for the Company
When discussing BIM design behavior standards, modeling standards are often the first to come to mind. However, the core lies in re-engineering the design process itself. BIM’s impact extends beyond deliverables; it transforms design workflows significantly.
1) First, revisit existing design behavior nodes under the traditional 2D design model, then plan new design processes aligned with BIM characteristics.
2) Modeling standards form the foundation but must serve deliverables. The value added at different design stages in BIM workflows needs to be clearly defined first, forming the basis for modeling standards that go beyond mere visual quality.
3) BIM mode minimizes additional work for collision detection and pipeline synthesis. Defining these checkpoints early helps identify and resolve design errors promptly.
4) Projects executed under enterprise BIM design behavior standards tend to achieve higher quality, assuming all other factors are equal.
3. Reassessing and Developing Design Delivery Standards (Internal and External) in BIM Mode
Delivery standards and design behavior standards are closely linked and form two critical pillars of enterprise BIM standards.
1) Similar to behavior standards, start by thoroughly reviewing deliverables under traditional 2D design modes and their phased outputs. Then clarify the relationship between BIM design outputs and conventional deliverables. For example, understanding how BIM models complement 2D drawings and identifying new deliverables under BIM that enhance design value. BIM models provide clearer, more precise explanations than 2D drawings, facilitating accurate material takeoffs and enabling 5D modeling. However, achieving this requires not only reusing BIM models but also innovating business models driven by enterprise management.
2) BIM-driven design process reengineering changes the definition of design content, which naturally alters deliverables. For instance, BIM-based deliverables offer greater value in detailed construction design and improve project budget management. The question remains: can processed BIM models be accepted as construction deliverables?
3) Despite the clear benefits of BIM deliverables, challenges arise due to their differences from current drawing standards, which often favor schematic representations. This precision gap can create temporary obstacles, requiring firms to develop counterstrategies. The recommended approach is to absorb these differences through reasonable additional costs and offset them through business innovation.
4) Ultimately, delivery standards must ensure that BIM-driven changes to design outputs serve as a foundation for deepening the firm’s operations, not just as a showcase of technical capability.
4. Collaborative Work Standards Based on BIM
Design firms have long followed principles of collaboration and developed standards to regulate team behavior and deliverables. Establishing an enterprise-wide collaborative work environment and clear regulations is fundamental to these standards. Different design models impact collaboration effectiveness, but the key lies in the firm’s understanding of collaboration and the creation of corresponding environments and policies.
1) Both the external reference approach in 2D tools like AutoCAD and the working set method used by BIM tools such as Revit support collaboration, but they are seldom fully utilized by firms. The primary factor enabling collaboration is the enterprise’s own mechanisms—specifically, well-defined and enforceable design habits.
2) Unrealistic expectations of an ideal collaborative information environment often hinder BIM adoption. For most firms, the foundational step toward collaboration is achieving centralized, complete, and networked management of design project data.
3) The essence of collaboration is ensuring the uniqueness of original data for every design deliverable. In BIM mode, the BIM project manager’s planning for data deliverables is especially critical and must align with the enterprise’s collaboration standards. For example, many firms struggle to maintain unique source data for all design drawings.
4) Developing collaborative work standards involves defining regulations and cultivating habits within the firm. While mature technical solutions exist, they are not yet fully applied. Pursuing overly idealistic goals often leads to implementation difficulties.
