Project Summary

The National Aeronautics and Space Administration

(NASA) Ames Research Center at Moffett Field, in

the heart of Californias Silicon Valley, conducts crit-

ical research and development for the space agency,

with a primary focus on supercomputing, net-

working, and intelligent systems. Recently, NASA

Ames initiated work on the Sustainability Base, a

$20.6-million facility designed to surpass standards

for LEED Platinum sustainable design certification

and approach net-zero energy consumption. When

complete, it will be one of the federal systems

greenest buildings and the first new NASA Ames

facility in 20 years. NASA Ames selected William

McDonough + Partners (WM+P) as design architect

and AECOM as architect of record for the project.

The WM+P and AECOM team provided a robust

combination of programming, architecture, interiorand landscape design, and LEEDconsulting as

well as structural, civil, mechanical, electrical, and

plumbing engineering services. Swinerton Builders

served as general contractor.

The Challenge

The buildings design challenges included a com

radial geometry, an innovative steel-frame exo

eton, and numerous eco-friendly features, such

geothermal wells, natural ventilation, high-perf

mance wastewater treatment, and a photovolta

roof, which will provide 30 percent of the build

power. The facility, which will house administra

and research groups, will also feature an adapt

building control system and a flexible, open flo

plan. Our ultimate goal was to create a self-su

ing building that produces virtually all of the en

it consumes on-site, says June Grant, the proje

manager for AECOM.

Budgetary restrictions forced NASA Ames to

accelerate the project timeline or risk loss of fu

ing. We needed a common platform that woulenable us to produce the project in a very quick

time frame, says Grant. In particular, it was cr

that the structural engineers and architects be

constant communication.

June Grant Project Manager AECOM

On this project, AECOM team members were

ased in San Francisco, Moffett Field, and Orange

ounty, California; Albuquerque, New Mexico; and

hoenix, Arizona. To connect the geographically

ispersed team, AECOM relied upon Autodesk

uilding information modeling (BIM) solutions,

ncluding AutodeskRevitArchitecture soft-

ware and AutodeskRevitStructure software,

omplemented by AutodeskNavisworksManage

oftware, AutodeskEcotectAnalysis software,

nd tools based on the AutoCADplatform, such

s AutoCADMEP software. These powerful tools

elped provide the rapid responses we needed on

his complex, fast-track project, says Tom Horan,

ice president at AECOM and AECOMs site director

t NASA Ames. NASAs support for using BIM on

his project is in alignment with its mandate requir-

ng BIM use on all projects exceeding $10 million

hat are initiated after October 2010.

he Solution

o better obtain the full benefits of the BIM

pproach, design architect WM+P used Revit

rchitecture software to help develop the initial

model and perform preliminary structural and

mechanical studies before passing the model on

o AECOM. That enabled the engineers to move

orward, while we continued design work on the

xterior skin, says Alastair Reilly, director at WM+P.We were an integrated team working together in

eal time.

Revit Architecture was an ideal solution for the

buildings complex, radial geometry. Every poten-

tial design change had numerous implications,

says Horan. The BIM process, supported by Revit

Architecture, helped us understand those implica-

tions, communicate them to the other team mem-

bers, and make faster, more-informed decisions.

Revit Architecture also enabled AECOM to more

quickly examine and evaluate multiple design sce-

narios. For example, at one point during the design

process, rapidly rising material prices forced the

team to change the design in order to stay within

budget. The model enabled us to adjust the floor-

to-floor heights more quickly so that we were able

to save enough on material costs to help meet the

budget requirements, says Horan.

Link the Disciplines

One of the most visible aspects of the new facility

was its innovative steel-frame exoskeleton, which

required close coordination between the architects

and structural engineers, who were using Revit

Structure software. A common BIM software

platform enabled the architects to avoid duplicat-

ing the engineers work, says Horan. They could

more quickly see how structural changes impacted

the architecture.

This level of connectivity helped increase design

accuracy. For example, when the structural engineer

adjusted a piece of steel, Revit Architecture auto-

matically flagged the change, informing the project

manager that the connections no longer worke

For added design accuracy, the team conducted

weekly clash detection with Navisworks Manag

Attain the Highest Efficiency Standards

Our clients goal was never simply to get to LEED

Platinum, says Horan. That was understood as a

baseline. Right from the start, AECOM examined

local climatic conditions and how the sun moved

across the sky throughout the year, searching for

ways to take advantage of passive solar lighting in

the building. To help meet the projects exactingsustainability standards, AECOM exported data

from the model to a variety of analysis software

applications, including Ecotect Analysis. AECOM

used these tools to compare the performance of the

lighting layout against the teams goals, designing,

fine tuning, and analyzing in a constant loop.

Traditional office spaces hide behind high walls,

says Grant. To encourage collaboration, AECOM

wanted to introduce a new culture of lower

walls and open spaces. With data from the Revit

Architecture model, AECOM used Ecotect Ana

to investigate how far sunlight would extend in

the buildings open workspaces. That helped u

determine the impact that lower partition wall

would have on energy consumption and gave u

valuable feedback about the design.

WM+P also utilized information from the RevitArchitecture model, using Ecotect Analysis to b

understand the cost impacts of its design decis

particularly around floor-to-ceiling heights and

gration of daylight into the design. We were a

to optimize the daylighting, making sure that w

we created worked for the benefit of the buildi

from both an engineering and cost standpoint,

Reilly. Ecotect Analysis helped us study the im

of potential design changes faster, more effect

and earlier in the design process.

ncrease Coordination

During construction, which began in August 2009,

he contractor, Swinerton Builders, imported the

evit Architecture model into Navisworks Manage

oftware, using it as the foundation for further

ash detection. Our mechanical, electrical, and

lumbing; fire protection; and sprinkler system

ubcontractors created models using AutoCAD

MEP and other CAD tools, says Daniel Gonzales,

EED AP, corporate manager of virtual design and

onstruction at Swinerton Builders. Twice a month,

we imported all of these models into Navisworks

Manage and performed clash detection, using the

evit Architecture model as background.

winerton has fully adopted model-based coordina-

on. In past projects, these bimonthly coordination

meetings required members of the contracting

eam to gather in a conference room around a light

able. A single meeting could last up to five hours,

ot including travel time, says Gonzales. With help

rom Navisworks Manage, Swinerton and the sub-

ontractors were able to conduct online coordina-

on meetings that typically lasted no more than 90

minutes. Use of Navisworks Manage is standard

ractice at Swinerton. It provides a tremendous

ompetitive advantage.

s the design developed, AECOM exported the

evit model to a third-party application for energy

nalysis by the teams high-performance build-

ng engineers, who supplied feedback on window

zes and locations, helping the team validate the

esign direction. We were able to fine-tune the

esign within a very short time frame, says Grant.

Typically, on a project like this, you would not have

chance to do that much benchmark testing to

make sure you are performing according to your tar-

ets. Revit Architecture software and its ability to

alk to other applications helped make the process

elatively easy.

howcase the Future

ASA Ames wanted the completed building to

erve as a platform for experimentation with

dvanced technologies. One such technology is the

uildings integrated control system. The build-

ng was designed to operate as an intelligent unit,

where the shading devices, lights, windows, andentilation are all driven by monitoring devices and

omputers, says Horan.

ucescan help NASA Ames reduce energy usage.

or example, to prepare a conference room for a

reviously scheduled meeting, the system can fac-

or in current weather conditions and the number

f people in attendance and adjust the thermostat

he Result

onstruction on the project is scheduled for

ompletion in early 2011. Using Autodesk BIM

olutions, we completed the drawings and design in

bout nine monthshalf the time originally sched-

led for this project, says Grant.

Autodesk BIM solutions were a crucial component

in both the production of the design documents and

in the analysis required to evaluate our recommen-

dations, says Grant. They were the tools of choice

for communication because they help facilitate

dialogue and coordination within the design team.

We were very impressed.

WM+P shared Grants viewpoint. Although geo-

graphically quite dispersed, the team was integrated

through the BIM process and the model, says Reilly.

We were very happy with the results.

With as many offices as we have within AECOM,

the ability to collaborate is a top priority, says Brion

Boucher, AIA, LEED AP, the associate vice president

and director of design technologies for AECOMs

Planning Design + Development Group. The BIM

process helps us to utilize our best resources and

expertise from anywhere within the company to

deliver a consistent, high-quality product to our cli-ents. BIM is a very important initiative at AECOM.
