General contractor was Trepte Construction Co., of San Diego; and the masonry contractor was Custom Masonry, of La Mesa, Calif.
Hazard Products, Inc., San Diego manufacturer of concrete block, produced the 105,000 two-cell concrete block used in the structure. The block, specially fabricated for high-rise construction have a strength well over 3,000 psi. Over 50 different shapes and textures of 8 x 8 x 16" series block were used.
Designer J. V. Thompson said that the rapid construction of the 13-story building was "a tribute to a

dramatic and effective brand of teamwork between designers, engineers, contractors, and suppliers."
Typical of the time-saving innovations employed on the job was the method used to pump grout to the upper floors without installing a second pump at, perhaps, the seventh or eighth floor.
The problem was solved by pumping grout through a steel pipe, thereby reducing the friction that would have been evident in the conventional high-lift hose systems. Hoses were used, however, to distribute grout to work sites on each floor.
Another time-saving technique was devised by the masonry contractor and the block manufacturer. A complete "floor" of block was delivered from the Hazard plant to the job site the day following installation of ceiling-floor slabs. Blocks were pallatized and labeled for the rooms and areas where they were to be used.
Not only time but money was saved on the Catamaran Hotel project, according to Gene Trepte, of Trepte Construction Co.
