Motivations

2

Todays Market Value as US GDP$1.77 Trillion (13.4%) construction existingCommercialResidentialIndustrialInfrastructure$0.81 Trillion (6.1%) construction new ResidentialCommercial

3

Environmental Big Picture39% Primary US energy use38% CO2 emissions72% US electrical consumption14% All potable water40% Global raw materials25% Solid waste construction & demolition

4

Hang-ups to Wider Green AdoptionPerceived as added feature added costExperience is keyNo one-size-fits-all answerMany paths to greenPoorly defined goals at the onset

5

Greening Commercial Buildings26% lower energy usage13% lower maintenance costs33% lower greenhouse gas emissions27% higher occupant satisfaction

6

The Facts about Health and Production$17-48 Billion in healthcare cost savings$20-160 Billion in worker performanceIn the US, 90% of our time is spent indoorsIndoor pollution levels x10 higher than outdoorsPoor ventilation + higher CO2 concentrations, lead to Sick Building Syndrome

7

A Path to Attainment

Understanding Existing BuildingsVerify or generate documentationRecord operational needs / wantsLEED for existing buildingsDefine goalsQA/QCKeeping Records

The Importance of BIMBuilding Information Modeling (BIM) is a building design method that uses a database of coordinated, graphically rich, internally consistent, computable information in three-dimensional models for design, engineering, construction and facility management.

BIM will permanently change the AEC professions by 2015

Including universities, clients, design codes, contracts, insurance policies, global recruitment of staff, work process and many other aspects.

BIM bandwagon The nations largest architecture, engineering, and construction companies are on the BIM bandwagon in a big way

Getting the work done

Scanning WorkflowEstablish survey controlScan from multiple locationsRegister data to local datum

Scanning to BIM WorkflowRegistered point cloud modelspaceFit to

ArchitecturalStructuralMEP

Making the BIMTruView of actual point cloud

Object Modeling from Point Cloud

Measure a large number of points on the surface of an object

Point clouds themselves are generally not directly usable in most 3D applications

17

Object Modeling from Point Cloud

Converted to triangle mesh triangle models, NURBS surface NURBS models, or CAD models

Uses include: clash detection, interferences, retro-fit, and process simulations etc.

18

Modeled object fit to cloud Fitting algorithms use parts tables based on published specifications

Including geometric data (e.g., dimensions), derived properties (e.g., surface area, mass), and nominal information for each standard "part".

19

Modeled object fit to point cloud

Standard tables include the AISC (American Institute of Steel Construction) for structural shapes

20

Model object metadata

Export model objects to ASCII / DXF / COE (Cyclone Object Exchange)Support - AutoCAD, MicroStation via Cyclone COE Data
