Building Information Model • A Building Information Model is a data-rich, object orientated, intelligent and parametric digital representation of a facility, from which views and data appropriate to various users’ needs can be extracted and analyzed to generate information that can be used to make decisions and improve the process of delivering and maintaining the facility. • A parametric feature based modeler is a CAD software package that uses either constructive solid geometry or Boundary Representation that allows users to refer to features instead of the underlying geometry.
Building Information Modeling • Building Information Modeling is the process of creating intelligent models that will be shared across multiple platforms and with many different entities. These entities may include designers, builders, subcontractors, fabricators, machine operators, owners, and facility managers. Each entity is responsible for sharing information in a collaborative effort both upstream and downstream from their area of responsibility.
When Should I use BIM? Answer: When it Makes Since
BIM Use Prior to Award of Contract Understanding of Project (Sinking Hoist Model)
BIM Use Prior to Award of Contract • Presentations • Sequence of Work • Constructability Reviews • Logistics and Material Lay-down
BIM Use - Preconstruction • Collision Detection • Coordinating work with other trades
BIM Use - Preconstruction • Quantity Surveys • Revit Scheduling Tool
BIM Use - Preconstruction Estimating 3rd Party Estimating Software
BIM Use - Preconstruction • Project Scheduling • Navisworks Timeliner • Can you meet the schedule? • “What if?” Scenarios
BIM Use – Procurement • Project Models • Base Model for … • Lift Drawings • Formwork Drawings • Rebar Fabrication
Concrete Lift (Fabrication) Models • Each Concrete Pour a Separate Element or Group • POUR SPECIFIC QUANTITIES • EMBEDS • PENETRATIONS • DIMENSIONS
