TITLE: BIM for Cost Estimating and the Benefits of 4D/5D Modeling


Peter Starnes and Jay Mezher

Mott MacDonald

Peter Starnes: Peter has more than 25 years of experience in maritime civil engineering for infrastructure and transportation projects. He champions the use of Building Information Modeling (BIM) processes and provides leadership and guidance for collaborative working. He acts as information manager on BIM projects to ISO:19650, and devises and monitors suitable workflows for BIM processes, tailored to the needs of the project. Peter manages a team of BIM coordinators and is responsible for ensuring consistent quality and on-time delivery of technical models.

Jay Mezher NCARB, AIA: Mr. Mezher is a licensed architect and an experienced digital design and delivery professional, he serves as a director on advanced BIM/VDC/Digital Delivery topics, specific to the Transportation, Energy and Water Sectors. Mr. Mezher currently serves as the North America South America (NASA) Regional Digital Delivery Leader. With more than 18 years at a major engineering firm, Mr. Mezher has participated in projects including the BART Silicon Valley Phase II Extension, California High-Speed Rail, Alaskan Way Viaduct Replacement, SR 520 Floating Bridge (Seattle), Amtrak B&P Tunnel (Baltimore), East Side Access, Second Avenue Subway, LaGuardia International Airport, Eurasia Tunnel (Istanbul), and many others. Mr. Mezher has published articles and given presentations on BIM and virtual design and has taught at the Autodesk University conference and at George Mason University. He was honored for the innovative use of BIM and design software at the 2013 NCE International Tunneling Awards and has won awards for his work on the Alaskan Way Viaduct Replacement Program.

Synopsis: Peter Starnes and Jay Mezher discuss how BIM models can be used to bring greater confidence and clarity to the constructability and cost estimating process during design and construction phases. What is required to develop accurate quantity take off from 3D models and what are the benefits and limitations of adding time and cost dimensions.
