The document discusses Building Information Modeling (BIM) and its relevance for quantity surveyors and project managers. It provides an overview of BIM, including Level 2 Commercial Suite standards, Employers Information Requirements, and BIM protocols. It also discusses measurement standards like NRM 1-3. The document notes that effective communication is important when quantity surveyors extract cost information from BIM models, as design software and model structure may not directly align with measurement needs. It suggests gaining understanding of how designers approach projects and being aware of any data lost during file exports.

32. Helpful Hints – Quantity Surveyor
• Gain a basic understanding / appreciation of how designers
approach / structure a project
• Understand any work-around or limitations of the design
software
• Appreciate not everything is modelled
• May have to develop measurement libraries to extract and
interpret quantities / data from model for immediate use
• Be aware of any data ‘lost in translation’ between file exports

33. Helpful Hints – Designers
• Additional information may be needed to be inputted into
model in order for quantity take off to be completed from a 3d
model
• Unlikely that model data / structure will be compatible for
quantity take off in line with NRM’s.
• Unlikely that model data / structure can be broken into work
package structures of trade packages.

34. Helpful Hints - All
• Communication is vital
• Be clear about what your requirements are – retrospective /
abortive work is frustrating and costly
• Be honest! - Don’t over/under exaggerate your capabilities
• Sit with your team and review all aspects of models and the
required outputs together
