Motivations

Today’s Market Value as US GDP

$1.77 Trillion (13.4%) construction “existing” Commercial Residential Industrial Infrastructure

$0.81 Trillion (6.1%) construction “new” Residential Commercial

Environmental Big Picture

39% Primary US energy use 38% CO2 emissions 72% US electrical consumption 14% All potable water 40% Global raw materials 25% Solid waste construction & demolition

Hang-ups to Wider Green Adoption

Perceived as added feature added cost Experience is key No one-size-fits-all answer Many paths to green Poorly defined goals at the onset

Greening Commercial Buildings

26% lower energy usage 13% lower maintenance costs 33% lower greenhouse gas emissions 27% higher occupant satisfaction

The Facts about Health and Production

$17-48 Billion in healthcare cost savings $20-160 Billion in worker performance In the US, 90% of our time is spent indoors

Indoor pollution levels x10 higher than outdoors Poor ventilation + higher CO2 concentrations, lead to “Sick

Building Syndrome”

A Path to Attainment

Understanding Existing Buildings

Verify or generate documentation Record operational needs / wants LEED for existing buildings Define goals QA/QC Keeping Records

The Importance of BIM

Building 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 nation’s largest architecture, engineering, and construction companies are on the BIM bandwagon in a big way

Making the BIM

TruView 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

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.

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".

Modeled object “fit” to point cloud…

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

Model “object” metadata

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

Workflow Benefits

1. Exposing BIM to Facilities Management : BIM / CAD links to CAFM / GIS / O+M data

Locate SITE Locate BUILDING

Locate BUILDING QUADRANT§ Locate LEVEL

§ Locate ROOM§ Locate ASSET

§ Manage & Maintain§ Repair, Replace, Remove

2. BIM / CAD Translator – Rosetta Stone of Building Data: Normalize Data Flow between Authoring Tools: Revit, AutoCAD,

MicroStation, Excel, Access

Workflow Benefits

3. Manage and Validate – Comparer Edits made in CAFM to BIM model: Room, Space, Doors and FF+E Asset Data Export to COBie II

4. BIM Management – Kit of Parts for full Campus: BIM & CAD FF+E “Kit of Parts” for entire office / facility including O+M

docs data

5. Reduce Project BIM Size : Keep BIM “data” outside BIM Model Bidirectional Parameter data passed between BIM/CAD and Geo-

Database

Steps for Implementation of Full BIM Lifecycle Management

Analysis, Review & Documentation of Existing Facility Current Facility Management and Maintenance Workflow Modeling Existing Conditions (various reasons & LOD) Define BIM Overall Strategy

BIM Execution Plan for all New Projects Project Team, Models and Consultants Defined BIM Expectations BIM Standards Defined for all New Projects: Overall Facility "Kit of Parts“ Provide BIM Templates, Content and Workflow Provide Standard Conventions for Naming all Aspects of BIM

Establish Links and Workflow Between BIM / CAD with FM / GIS
