Design trends
Technology executes design more efficiently with less conflict
By Candy McCampbell
Design technology is changing the way south central architects
and contractors interact at the jobsite.
E-mail, three-dimensional drawings, interactive Web sites
and video conferencing are just a few of the technological
tools that architects and contractors use to execute design
more efficiently and with less conflict.
For example, at the Richard Sheppard Arnold U.S. Courthouse
in Little Rock, technology helped the mechanical and electrical
subcontractors stop on-the-job conflicts before they started.
"They used computer-aided design to produce drawings
and had a series of meetings to discuss the coordination of
work - the routing of pipes, conduit, HVAC vents," said
Michael Barker, project manager for Caddell Construction Co.
Inc., the general contractor.
"This was months before we started on the above-ceiling
work. It limits the number of conflicts we have during installation."
Electronic filing formats were also used at the site, said
John Greer Jr., a designer with architect Witsell Evans Rasco
of Little Rock. Drawings and specs were scanned as tiff and
pdf files, then posted to a closed Web site where contractors
could download and print whatever they want, he added.
The SmithGroup in Detroit, designer of a new research building
being built
at St. Jude Children's Hospital in Memphis, has relied extensively
on technology to communicate with contractor Skanska USA Building
Group at the site.
"If there is an issue in the field, we have the ability
to take a digital photo and e-mail it, then have a realistic
discussion," said Tim York, Skanska project manager.
"We don't have to wait three days until the architect
can get down here. We can make more informed decisions with
real information."
The architect can "instantly see what the other person
is talking about," said Tom Winkeljohn, project architect.
"We can easily discuss it simultaneously."
Five years ago, the parties were sending drawings back and
forth via FedEx, but today they can make changes in real time
from multiple locations using video conferencing, York said.
"Our cell phones, computers, e-mail and PalmPilots enable
us to communicate as much as we need to," said Steve
Kinzler, CEO of the Wilcox Group, a Little Rock architecture
firm.
"With e-mails now, we can ask questions of one another,
and with copies going to 12 people, someone might say 'I know
something about that.' It becomes an electronic communications
network" that accommodates input from several perspectives,
he said.
Technology, including 3-D modeling, "helps us with engineers,
and vice versa," Kinzler added. "We can really coordinate
our drawings back and forth better."
At first, architects were slow to give up the use of two-dimensional
drawings to illustrate a three-dimensional building, said
Chris Giattina, principal in Giattina Fisher Aycock Architects
in Birmingham.
"We were slow at grasping a fundamental change staring
us in the face, one that would completely change the way we
do business," he said.
The 3-D building information model allows architects, clients,
construction managers and other design team members to see
a column's depth and width, or to observe the structural needs
of a high-rise building.
Stephen Kulinski, principal at Gresham Smith and Partners,
an architect and engineering firm in Nashville, calls 3-D
modeling "the no-surprise school of design."
"It's easier to visualize," he said. "The
accuracy of a drawing is a whole lot higher now that everything
is done with computer."
PowerPoint and 3-D drawings are tools that Bruce Wood, partner
in JH&H Architects in Jackson, Miss., counts on, especially
for college and university building projects.
He stores photos of buildings that would work on a campus
and calls them up in client meetings to show what's out there.
"It's a great design tool," he said. "It helps
in consensus-building to show them immediately."
Three-dimensional software, for example, can show a client
how a church steeple would look with lighting at various wattages
and at different places on the structure.
"The process still takes as long, but it allows us to
make better decisions," Wood added. "We're making
decisions based on precise information instead of an educated
guess."
John Madole, senior project manager for American Constructors
Inc., general contractor for the Schermerhorn Symphony Center
in Nashville, said the ability of architects to communicate
three-dimensional designs to contractors at the jobsite "has
dramatically impacted the way we communicate."
The Schermerhorn's 28 designers are scattered across the
country.
"Most of our correspondence is now e-mail and pdf files,"
Madole said. "We receive it from designers in that fashion
and we transfer electronically to subcontractors and vendors
daily."
American Constructors also uses a modeling program so subs
can trouble-shoot problems that might not be apparent in the
drawings.
The subs' weekly meetings serve an important purpose, said
Randy Nale, senior project manager at Earl Swensson Associates
in Nashville, architect of record for the center.
"It avoids problems in the field because they're thinking
it through," Nale added. "They are all conscious"
of other trades working in the same area.
"One of the most important aspects of an architect's
job is to be an effective communicator," said Marshall
Anderson, principal in ArchitectureWorks in Birmingham.
"To that end, computers have made information - be it
product research, drawing files, 3-D models, or day-to-day
communication - much more accessible."
Jeff Carrico, vice president of White Spunner Construction
in Mobile, Ala., and project manager for the RSA Battle House
Hotel renovation in Mobile, said he doesn't know how a construction
team would function without communication.
"The Battle House is handled primarily by e-mail - the
architect, the design architect and engineers are in different
states," he said. All staff members carry a BlackBerry,
especially in the field to be alert to the arrival of new
design documents.
Jack Blake, associate principal at Thompson, Ventulett, Stainback
& Associates in Atlanta, architect for the Battle House
project, said technology has improved the speed of communication
and enabled quicker decision-making.
"We did 3-D modeling of the tower and the entire city,
so the owner could see what his tower would look like in the
city, the components of the building, the interior, the details,"
he said. That also was "conveyed to the contractor so
they could see how they were supposed to look," Blake
added.
A Web site will soon become a "must" at the jobsite.
"I've found that Web-based project management and e-mails
lead to more detailed and documented communication between
all parties," said Joseph Crain, principal in Guild Hardy
Architects in Biloxi, Miss.
Gresham Smith and Partners' Kulinski said a Web site has
"all of the correspondence, all of the drawings, any
of the information related to that job. I can put in information
the contractor can access and the contractor can put in information
that I can access."
