Modtech Holdings, Inc. (Company) (Nasdaq:MODT) recently completed a $15 million school project for the School Board of St. Lucie County, Florida.

Specification work began in February 2006, the first order was received in early March, and in early April the first units rolled off the production line. By the end of July, Modtech's 120,000 square-foot facility in Plant City, Florida, had constructed eight complete school additions, including a total of 174 classrooms, in different configurations including cafeterias, laboratories, and teacher planning areas.

Key to the success of the project was the use of side-stackable classrooms, a new design concept being offered by Modtech. Also contributing to the relatively short time-to-completion were the ongoing communications and contact between the Modtech operations team and the entire St. Lucie County facilities staff. Project Manager Mike Durette was particularly helpful in assuring that all requirements of the schools' principals and School Board were satisfactorily met.

Rich Dalia, Modtech regional sales manager in Florida, remarked, "The coordination and cooperation that were required to accomplish this feat is unparalleled in my 21 years of industry experience."
