How are we doing this?CommunicationDefine the correct level of detail and abstractionMutually crafting a process that has enhanced an integrated practice approach, while further strengthening our relationships

ObjectivesEliminate Miscommunication / Uncertainty / ReworkEnhanceCoordination / Analysis / Program Validation

What Has Been Accomplished?

Reduction in field changes, tightened subcontractor bids, and improved information flow throughout the design and construction process.

Clarity in design communications based on BIM visualization platforms. Three dimensional presentations of information allow everyone to see the project components and how they work together. This quickly and clearly conveys ideas and intent.

Higher quality design that is not delayed during construction because of rework.

What Has Been Accomplished?Ability to identify collisions

Ability to visualize what is being built in a simulated environment resulting in fewer errors and corrections in the field

Higher reliability of expected field conditions, allowing for opportunity to do more prefabrication or materials offsite, which is usually of a higher quality at a lower cost

The ability to do more what if scenarios, such as looking at various sequencing options, site logistics, hosting alternatives, cost, etc.
