Insurance on a Fireproof Water Tank.

Insurance on a Fireproof Water Tank.

The cost of insurance on a steel water tank and tower of the Victor Talking Machine Company, Camden, N. J., was reduced by enclosing the tower legs and horizontal braces in concrete. The 100,000-gallon tank was carried with its bottom 125 feet above the ground. Old buildings adjoined the tower on both sides, and the indemnity insurance covering possible damage to them in case of collapse of the unfireproofed tower, was quoted at $500 per year. E. G. Perrot stated before the National Association of Cement Users that it was decided to fireproof the structure at a cost of $4,000 and dispense with insurance. At 6 per cent, this gives a carrying charge of only $240 per year, and at the same time the tower is protected from the elements and is considered absolutely fireproof. The rod diagonals were not fireproofed, and heavy reinforced concrete kneebraces were built in to take the load if the rods were rendered ineffective by fire.
