Marty Corrado, project executive for field operations in Skanska USA Building Inc.’s Nashville office, knows this better than most contractors. He went out on a limb to bring multitrade prefab to a Dayton, Ohio, hospital project in what is considered the most ambitious effort to date in the U.S.

“There has to be a better way to build our buildings,” says Corrado, who describes himself as someone who likes “to push people to ‘work outside the box’ ” and not always fall back on old routines.

After careful study of Skanska’s multitrade prefab operation in London, Corrado set up a prefab operation in a rented warehouse in Dayton so workers could build 178 identical patient rooms and 120 overhead corridor utility racks. The components ultimately were trucked to and lifted by crane onto the 484,000-sq-ft Miami Valley Hospital Southeast Hospital Addition.

Multitrade Prefab具有单贸易预制措施的所有优势：受控环境，提高工人安全性和提高的生产率。该方法还消除了在事物顺序合作的行业中的草皮战，并最大程度地减少了浪费。

But multitrade prefab changes a project’s rhythm. For example, certain design decisions had to be accelerated several months, says Tim Fishking, a principal in the Columbus, Ohio, office of architect NBBJ.

这就是为什么要使多层预制措施取得成功，全队合作和制作态度的态度，必须是必须的。他补充说，他非常支持他希望多局预制的想法是他的过程。

In the end, Corrado’s strategy cut more than two months off the schedule and 1% to 2% off the cost of the 12-story hospital, which opened in December.

Corrado thinks the approach is going to spread like wildfire. “This is going to revamp the entire hospital delivery process as we know it,” he says.

Skanska already is using the process on two more hospitals: one in Miami, Fla., and one in Western Virginia. But Corrado has set his sights beyond medical centers. “We are now evaluating every project we pursue to determine how the multitrade prefab approach will fit,” he says.

由于对这个想法的最初抵制，科拉多说，他经常感觉像一只猫，里面有一条长长的尾巴，里面装满了摇椅。但是反对者激发了他证明他们是错误的。他说：“当周围的几乎每个人都告诉您不会做一些工作很有趣。”

“Marty has always been a risk taker,” says his father, Vince Corrado, chairman of the board of Shook Construction, Dayton. The MVH project was a joint venture of Skanska and Shook.

The elder Corrado counts his son’s skills as a communicator and listener and his great sense of humor as keys to the operation’s success. “Marty was able to bring together both union and non-union tradespeople for the common good of the project,” he says.
