Estimating in construction has evolved since the beginning of Building Information Modeling (BIM). Receiving models in preconstruction has enabled construction estimators to understand a building better than ever. If models are not provided, having the virtual design and construction (VDC) team that we have enables us to quickly create models to understand and provide high-level overviews of spaces that need an estimate for a DD, SD, or even proposal estimates. Understanding how to prepare these models for an estimator is important, and details that they need are often overlooked. We've developed templates that correspond with what our estimators are looking for and how they want to see the information. Some techniques we use take any architectural model and make it usable in the estimating world, providing better-informed and better-understood estimates. This session features Revit.
- Understand the link between BIM and estimating
- Learn Revit-model data overview and organization techniques
- Learn about viewers for estimators that cannot or will not use Revit
- Get quick tips for preparing models for estimating
Melinda Hoffman is the virtual construction manager at LPCiminelli, one of the largest construction firms in upstate New York. Melinda leads all of the company's Building Information Modeling (BIM) and virtual design and construction (VDC) efforts, and she specializes in Revit software, Navisworks project review software, 3ds Max Design software, InfraWorks software, and visualization. She is the in-house Revit trainer and has presented Revit and BIM concepts to numerous clients and at conferences. She has been incorporating VDC and BIM in the construction industry to produce better quality projects, and she has been using 3D CAD products for the past 12 years.
Melinda Hoffman manages the emerging Virtual Design and Construction department at LPCiminelli, handling all the Building Information Modeling (BIM) mobile technology with a 5person staff. Her duties include training Revit software, aiding in prebid estimating and visualizations, managing workloads for staff, laser scanning to document existing conditions, managing model logistics, and scheduling and coordinating. She assists project teams with preconstruction services to establish and implement virtual construction procedures and techniques to assure timely modeling. She collaborates with the clients’ design teams and inhouse estimating on the use of models for 5D quantity takeoff and pricing. Hoffman leads clash detection and radio frequency interference (RFI) resolution with project teams during preconstruction efforts. Additionally, she assists with the creation of marketing visualizations to convey logistics plans during business development efforts.
