Most contractors today are familiar with the use of two way radio systems by producers of ready mixed concrete to facilitate communication between batching plants and the truck mixer fleets. Not so familiar is the fact that contractors themselves are also adapting this excellent communications method to their own needs. For example, Richard Carter and Son is a concrete forming and pouring outfit in the residential construction field. With the bulk of business occurring in two peak seasons, keeping the customers happy could become one big headache. The company has three top notch supervisors and a general manager who struggle constantly with the problem of operating in about four different places at once. The solution proved to be a two way radio system that keeps the field men in constant touch with the office. The system works fine and it is doing an excellent job. With mobile radios in the supervisors' vehicles about 30% more of their time is spent where it is needed.
