4 Course Description This presentation will focus on the successful utilization of VDC Deliverables in the design process of a 55 story high-end residential building in Manhattan. The main design concept was derived from extensive view analysis with the objective to maximize views, thus to maximize the condo and rental value. The architectural response to the view analysis is a sculptural freeformed tower corresponding to views. This presentation will allow for attendees to understand owner-derived priorities, recognize flexibility of a VDC work-flow, and identify value brought to projects through use of VDC solutions.

5 Learning Objectives At the end of this presentation, attendees will be able to: Attendees will be able to understand owner-derived priorities. Attendees will be able to recognize flexibility of a VDC workflow. Attendees will be able to identify value brought to the project through the use of VDC solutions.

26 Challenge Unit Packer Maximize revenue through optimal combination of unit types and sizes. Solution Unit Packer provided most efficient arrangement of unit types based on client s knowledge of unit type needs and profit margins.

27 Design Objectives

28 Unit Packer Step 1: Extract view values to spreadsheet

29 Unit Packer Step 3: Map values to floor plate perimeter

30 Unit Packer Step 4: Repeat until Desired Unit Mix is met. = 52 = 102 = 51

31 Summary Collaborative design process Client: view, unit, market values Architect: computational evaluation, form making Time- and cost-efficient deep analysis View values Multiple layout options Building envelope Better Decision Making

32 Design Concept Curve gradually transitions responding to views Balcony depth increases with distance views

33 Challenge Sculptural form Coordinate unique conditions efficiently Solution Scripted Master Model

40 Example 2/4: Maintaining Alternatives Maximum Flexibility Façade Alternatives A B C Double Ridge Smooth Stepped

41 Example 3/4: Optimized POINT CLOUD Tight Control / Tight Deadlines

42 Example 4/4: Fine-tuning Constraints Better Decisions # of curved panels COST EFFICIENCY MASTER MODEL ZONING BALANCED SOLUTION Maximize gross area FABRICATION CONSTRAINTS Avoid small radii
