METRICS 1. Avoided Rework – $15,000 to rework concrete & ductwork – Schedule benefits 2. Condensed Steel Schedule – $30,000 in crane costs & GC’s Submittals Fabrication Material Delay Submittals & Fabrication Design and Submittals Integrated Metrics & Results COSTS 1. Minor Model Creation Costs 2. ~$15,000 Software Costs 3. No Additional Hardware Costs 4. No Additional Process Time Metrics & Results MODEL WEAKNESSES Non-BIM Schedule Rework Issues BIM Schedule Construction Efficient Construction Operations Construction Time Savings • Not practical to model every detail • Models can contain errors • Non-model details can create problems • Updates are lacking after coordination • Contractors may not build per model New Soffits Lessons Learned Not Modeled AV Conduits 3. Avoided Scaffold Costs – $10,000 Savings – Schedule Benefit METRICS 4. CM Time Savings – Better & Quicker Understanding – Less End of Project Issues Metrics & Results AGENDA Barton Malow BIM Philosophy South Lawn Overview Metrics & Results Lessons Learned New BIM Applications CONTRACT LANGUAGE • What? – What systems should be modeled? – What level of detail is needed? – What is the purpose of the models? • When? – When should the first models be completed? – When should updated models be shared? – Is an as-built model required? • How? – Which file types are accepted? – How are models to submitted? – Who integrates and reviews files?
