When work started last summer on the seven-story, $35-million expansion of the Sandestin Beach Hilton Hotel, Destin, Fla., contractor Roy Anderson Co., Gulfport, Miss., was faced with the task of adding 200 rooms and 60,000 square feet of commercial and meeting space. Clearly, the job would be formwork-intensive, requiring many different wall lengths, several elevator shafts and a multitude of pilasters.
John Prine, project superintendent for Roy Anderson, reviewed his options for wall forming and decided to go with the Manto system manufactured by Safway Steel Products Inc., Waukesha, Wis. With only two main components -- steel-framed panels and clamps to align the panels and act as walers -- the wall forms can be assembled quickly and have few loose parts. Another advantage of the system is its strength. Cross ribs spaced 11.8 inches on-center on the backside of each panel provide enough support that the manufacturer rates the system for loadings up to 1,650 pounds per square foot. This means workers can place concrete for a full panel height in a single continuous pour.
