How to manage requirements, building information modelling (BIM) coordination, changes and design knowledge
In this business area, the greatest value is created by a traceable chain of requirements and design data. It is recommended to start with a clearly bounded first process and expand the solution in stages.
The design service includes requirements clarification, development of discipline solutions, model coordination, checks and handover of documents to construction. At each stage it is important to maintain a clear solution version, responsibility and approval status.
An early decision determines subsequent quantities, cost, construction method and operational characteristics.
A change in one system can affect structures, architecture, quantities and construction sequence.
It is important to know not only the latest file, but also who, why and when approved a specific solution.
Reuse of details, calculations and solutions depends on their structure and approval status.
The design market is moving from separate models and drawings towards a process governed by requirements, versions and data quality rules. BIM value is increasingly assessed by whether model information is suitable for coordination, quantities, construction and subsequent asset use.
Functional, technical, budget, timeline and operational requirements are collected.
Design options are compared, decisions are justified and assumptions are recorded.
Models, calculations, specifications and interdependencies are developed.
Conflicts are checked, comments are recorded, and the impact of changes is assessed.
Rule-based and specialist review checks are carried out.
Models, documents and approved solutions of appropriate detail are prepared for further use.
Models, drawings, requirements and comments are kept in personal folders or emails, and the approved version is determined manually.
Drawings and models are created digitally, but requirements, comments and approvals are scattered across email and folders.
Project documents and model versions are kept in one environment, but discipline processes and data standards are not yet uniform.
Models, comments, responsibilities and validations are managed consistently, and standard objects and classifiers are standardised.
Customer requirements are linked to model elements, automated checks, quantities and the impact of changes.
Parametric models, AI and project history help to evaluate options, risks and solution suitability whilst maintaining expert control.
The greatest loss of design margin is often caused not by modelling, but by rework: changed requirements, conflicts detected late, and unclear approved versions. A traceable requirement-to-solution chain for a single project enables measurement of rework and coordination costs.
The first priority is the process for requirements, model coordination, comments, and approvals within a single project.
